Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the application provides a method for inquiring state information, which can be applied to any intelligent home (which can be called as a first intelligent home) in a wireless mesh network. The intelligent home can be an intelligent refrigerator, an intelligent fan, an intelligent lamp and the like, and the embodiment of the application is not limited. In the embodiment of the application, each smart home in the preset area can form a wireless mesh network. For example, smart homes in a user's home may form a wireless mesh network. Specifically, each smart home can be provided with a communication module, and the communication module can carry a mesh protocol stack. After each intelligent home is started, each intelligent home can establish a wireless mesh network based on a communication module carrying a mesh protocol stack. Any strategy for establishing a wireless mesh network in the prior art may be applied to the embodiment of the present application, and the embodiment of the present application does not limit this.
In an example, node role assignment may be performed first, where a smart home (such as a smart router) capable of directly connecting to the internet is assigned as a root node, and the root node scans the signal strength and the node device type of a node to be assigned, and a device with higher signal strength, which can meet the requirement of forwarding data and is not low in power consumption is assigned as an intermediate node, otherwise, it is assigned as a leaf node. The distributed intermediate nodes scan the rest nodes to be distributed, and the node types are distributed according to the signal intensity and the equipment types, so that the establishment of the wireless mesh network is completed after all the node types are distributed layer by layer.
The following describes in detail a method for querying status information provided in an embodiment of the present application with reference to a specific implementation manner, and as shown in fig. 1, the specific steps are as follows:
step 101, receiving a first state synchronization message sent by other smart homes in a wireless mesh network.
The first state synchronization message contains state information of other intelligent homes.
In the embodiment of the application, each smart home can form a wireless mesh network. Fig. 2 shows a wireless mesh network provided in an embodiment of the present application. Each smart home in the wireless mesh network may communicate with any other smart home, for example, a certain intermediate node in the wireless mesh network may communicate with other nodes connected thereto, and the leaf nodes may communicate with the intermediate node and may communicate with a node at a further remote end through the intermediate node.
The intelligent home in the wireless mesh network can send own state information to other intelligent homes. In one case, when each smart home comes online, each smart home may acquire its own status information and broadcast the status information to other smart homes in the wireless mesh network, so that each smart home stores the status information of all smart homes in the wireless mesh network. In another case, when the device status of a certain smart home in the wireless mesh network changes, the smart home may also broadcast the status information to other smart homes in the wireless mesh network, so that each smart home updates the status information of the smart home.
In the embodiment of the application, each smart home can send the state information through the state synchronization message. The protocol used by the status synchronization message may be determined by a skilled person, and the embodiment of the present application is not limited. After receiving the state synchronization message (i.e., the first state synchronization message) sent by other smart homes, the first smart home may analyze the first state synchronization message to obtain the state information included in the first state synchronization message.
And step 102, updating a local equipment state table according to the state information of the equipment and the received state information of other intelligent homes.
In the embodiment of the application, the first smart home can update the local device state table according to the state information of the device and the received state information of other smart homes, so that the local device state table is consistent with the device state tables of other smart homes.
The equipment state table can be established in each intelligent home, and the equipment state table is used for storing state information of each intelligent home in the wireless mesh network. As shown in the first table,
watch 1
Referring to table one, the device status table may contain a device status table and a status log table. And each behavior of the equipment state table is state information of the intelligent home. That is, the status information may specifically include a device status and a status log.
The device state may specifically include an intelligent home device identifier and all states of the intelligent home from the start to the current time, and the state log may include a change time when the device state changes, the device identifier, and the changed device state.
The device identification may be a device identifier, a physical address, etc. The device state may include device switches, device functions, and the like. For example, a smart home is an appliance, and the device status may include an on/off status, an operation mode, a fault condition, and the like. If the smart home is a sensor, the device state may be an event detection result of the sensor; if the smart home is a gateway device, the device status may be a network connection status, a network speed, etc.
Taking the intelligent lamp as an example, the device states of the intelligent lamp 1 are as follows in sequence: closing, opening and closing; the corresponding log entry may be: 20: 00 smart lamp 1 off, 20: 10 smart lamp 1 on, 22: 00 smart lamp 1 is off.
Optionally, the updating of the device status table may be specifically divided into the following two cases.
In the first situation, each smart home is in an initialization state, and in this situation, the first smart home directly stores the state information of the device and the received state information of other smart homes in a local device state table.
In the embodiment of the application, the initial equipment state table in the smart home is empty, and when each smart home is online, initialization is performed, for example, a wireless mesh network is established, and then the equipment state table is initialized. Each smart home acquires its own state information, stores the current state information of the device in a local device state table, and broadcasts the state information to other smart homes in the wireless mesh network. After receiving the state information sent by other smart homes, the first smart home can store the received state information of other smart homes in a local device state table. The process of broadcasting the status information will be described in detail later.
And in the second situation, each intelligent home is in an operating state, and at the moment, the first state synchronization message is a state synchronization message sent by other intelligent homes after the state is changed. In this case, the first smart home updates the state information corresponding to the other smart homes in the device state table to the state information in the first state synchronization message. And the first smart home can judge whether the equipment state of the first smart home changes, and if the equipment state of the first smart home changes, the state information corresponding to the equipment in the equipment state table is updated according to the changed equipment state.
In the embodiment of the application, when each smart home is in an operating state, the equipment state may be changed, for example, the smart refrigerator is changed from a power saving mode to a quick-freezing mode. When the device state of a certain smart home in the wireless mesh network changes, the smart home may also broadcast the state information to other smart homes in the wireless mesh network. After receiving the state information sent by other intelligent homes, the first intelligent home updates the state information corresponding to the intelligent home in the equipment state table into the state information in the first state synchronization message. The process of broadcasting the status information will be described in detail later.
Meanwhile, the first smart home can also monitor the state of the device in real time, and can judge whether the state information of the device changes, and if so, the state information corresponding to the device in the device state table is updated according to the changed state of the device. Specifically, the changed device status may be added to the device status table, and the change time when the device status is changed is recorded, so as to generate a status log for the device status and add the status log to the status log table.
Based on the above processing procedure, each smart home may store state information of all smart homes in the wireless mesh network.
And 103, sending the stored equipment state table to the upper computer when receiving a state query request sent by the upper computer.
In this embodiment, the upper computer may be a terminal having data processing and communication functions, for example, may be a terminal device of a user or a terminal device used by a technician. When the upper computer needs to perform state query, the queried target smart home can be determined firstly. The target intelligent home can be randomly selected by the upper computer or can be intelligent equipment with the maximum signal intensity detected by the upper computer. And then, the upper computer sends a query request to the target smart home. And the target intelligent home sends the stored equipment state table to the upper computer.
Therefore, the state information of all the intelligent homes in the wireless mesh network is stored in each intelligent home, so that when the upper computer queries the equipment state, the upper computer does not need to request the state of each intelligent home, only the equipment state table of one intelligent home needs to be queried, the network delay encountered during the query of the upper computer is reduced, and the required network bandwidth is also reduced.
Optionally, taking the first smart home as an example, the embodiment of the present application further provides a process of broadcasting the status information by the smart home, which is specifically as follows.
In view of the first situation, when the first smart home is online, the state information of the device is acquired, and a second state synchronization message is sent to other smart homes in the wireless mesh network, where the second state synchronization message includes the state information of the device, so that the other smart homes update their own device state tables.
In the embodiment of the application, after the wireless mesh network is established, the communication module of each smart home acquires the current equipment state, generates the state log aiming at the equipment state, and stores the equipment state and the state log into the corresponding table entry of the equipment. At this time, the device state table of each smart home only contains its own state information.
To complete the device status table, each smart home in the wireless mesh network broadcasts its own status information. Therefore, each smart home broadcasts its own state information after delaying for a random period of time.
In view of the second situation, after the first smart home is on line, if it is detected that the device state of the device changes, a third state synchronization message is sent to other smart homes in the wireless mesh network, where the third state synchronization message includes state information of the device, so that the other smart homes update their device state tables.
In the embodiment of the application, when the equipment state of the first smart home is changed, the smart home updates the state information of the first smart home and broadcasts the updated state information. After receiving the update message, other smart homes update the local device state table according to the state information in the update message, so that all the device state tables locally stored in the devices in the network are synchronized. Thus, each device will have a real-time status of the other devices.
Optionally, due to the existence of network delay, the arrival times of the messages may be inconsistent, and even in the case of poor wireless conditions or network environments, there may be a possibility of packet loss. Therefore, the device state table of each smart home may be inconsistent. In order to avoid asynchronization of the equipment state table caused by packet loss, the communication module of each intelligent home can regularly request other intelligent homes to compare the equipment state table, and therefore synchronization of the equipment state table is achieved. As shown in fig. 3, the specific process includes the following steps.
Step 301, detecting signal intensity of other smart homes, and determining a second smart home with the largest signal intensity.
In the embodiment of the application, first intelligent house can detect the signal strength of other intelligent houses, wherein, this signal strength can be wifi signal strength, bluetooth signal strength etc.. Then, the first smart home may determine the smart home (second smart home) with the greatest signal strength.
Step 302, a first comparison request containing a device state table is sent to a target home device, so that a second smart home determines whether state information to be updated exists in the device state table of the first smart home according to the device state table stored in the second smart home, and if so, an update message is sent to the first smart home, wherein the update message contains content information corresponding to the state information to be updated in the second smart home.
In this embodiment of the application, the first smart home may send a comparison request to the target home device, where the comparison request includes a device state table (for convenience of distinguishing, it may be referred to as a first device state table) stored by the first smart home device. After receiving the comparison request, the second smart home determines whether the state information to be updated exists in the device state table of the first smart home according to a device state table (which may be referred to as a second device state table for convenience of distinction) stored in the second smart home, and if so, sends an update message to the first smart home, wherein the update message includes content information corresponding to the state information to be updated in the second smart home. If not, no processing is required,
and 303, receiving an update message sent by the second smart home, and updating the state information to be updated according to the content information in the update message.
In the embodiment of the application, the first smart home may receive the update message sent by the second smart home, then obtain the content information in the update message, and modify the entry corresponding to the state information to be updated in the first device state table into the content information in the update message.
Optionally, the manner of determining whether the state information to be updated exists may be various, and the embodiment of the present application provides two possible implementation manners.
The first mode can be judged through the state log. Specifically, for each smart home, a first state log corresponding to the smart home in a first device state table is compared with a second state log corresponding to the smart home in a second device state table. Then, the update time of the status log is obtained, wherein the update time is the change time closest to the current time in the status log.
And if the updating time of the first state log is before the updating time of the second state log, the first equipment state table is not updated in time, and the second intelligent home determines the state information corresponding to the intelligent home as the state information to be updated. And the second smart home sends an update message to the first smart home, wherein the update message contains content information corresponding to the state information to be updated in the second smart home, so that the first smart home can update the state information.
And if the updating time of the first state log is later than that of the second state log, the second equipment state table is not updated in time, and the second intelligent home updates the state information of the intelligent home in the second equipment state table into the state information of the intelligent home in the first equipment state table.
If the update time of the first status log is the same as the update time of the second status log, no processing is performed.
For example, the smart home a stores a device state table a, the smart home B stores a device state table B, and the smart home a sends a comparison request to the smart home B. In the equipment state table a, the equipment states of the intelligent lamp 1 are as follows in sequence: closing and opening; the corresponding log entry may be: 20: 00 smart lamp 1 off, 20: 10 the smart lamp 1 is switched on. In the equipment state table B, the equipment states of the intelligent lamp 1 are as follows in sequence: closing, opening and closing; the corresponding log entry may be: 20: 00 smart lamp 1 off, 20: 10 smart lamp 1 on, 22: 00 smart lamp 1 is off. Determining that the state information to be updated exists in the equipment state table a, and then sending the state information of the intelligent lamp 1 to the intelligent home A.
And in the second mode, the judgment can be carried out according to the equipment state. Specifically, for each smart home, a first device state sequence corresponding to the smart home in a first device state table is compared with a second device state sequence corresponding to the smart home in a second device state table. Then, the update time of the status log is obtained, wherein the update time is the change time closest to the current time in the status log.
If the number of the equipment states contained in the first equipment state sequence is smaller than the number of the equipment states contained in the second equipment state sequence, it is indicated that the first equipment state table is not updated in time, and the second intelligent home determines the state information corresponding to the intelligent home as the state information to be updated. And the second smart home sends an update message to the first smart home, wherein the update message contains content information corresponding to the state information to be updated in the second smart home, so that the first smart home can update the state information.
If the number of the equipment states contained in the first equipment state sequence is larger than the number of the equipment states contained in the second equipment state sequence, it is indicated that the second equipment state table is not updated in time, and the second intelligent home updates the state information of the intelligent home in the second equipment state table into the state information of the intelligent home in the first equipment state table.
If the number of device states included in the first device state sequence is equal to the number of device states included in the second device state sequence, no processing is performed.
For example, the smart home a stores a device state table a, the smart home B stores a device state table B, and the smart home a sends a comparison request to the smart home B. In the equipment state table a, the equipment states of the intelligent lamp 1 are as follows in sequence: closing and opening. In the equipment state table B, the equipment states of the intelligent lamp 1 are as follows in sequence: closing, opening and closing. Determining that the state information to be updated exists in the equipment state table a, and then sending the state information of the intelligent lamp 1 to the intelligent home A.
Similarly, the first smart home may also receive a comparison request sent by another smart home, and then perform comparison, where the specific comparison process is similar to the above process, and is not described herein again.
