Description

Multi-sensor data acquisition and spread devices and safety monitoring systems

The present invention provides a multi-sensor data collection and propagation device and safety monitoring that lowers the false positive rate of electricity, gas, and fire through multiple sensors and provides curation information to effectively respond to various risks and prompt situation propagation in conjunction with it It's about the system.

A sensor or detector is used as an information detection device that converts physical energy such as temperature or light gas into an electrical signal. For example, a smoke sensor installed indoors for indoor fire recognition and detection is a device that detects smoke and outputs the detection result as an electrical signal, but the smoke sensor's sensitivity may vary depending on the ambient temperature and ambient humidity of the place where the smoke sensor is installed. When falling, the smoke sensor becomes difficult to function. This problem may be common to other sensors as well. For example, the detection result of the earth leakage sensor, the gas sensor, the temperature sensor, the humidity sensor, etc. may vary depending on the intervention of environmental factors. Therefore, all detection sensors installed in the field for various safety have been proposed for sensors that accurately detect the field condition without being affected by surrounding environmental factors, and normally output a detection signal according to the detection result to reduce the false positive rate, but the situation is insufficient. am.

For example, in order to prevent fire and gas poisoning accidents, it is necessary to install a fire detector and a gas poisoning detector, but the existing detectors use only a single sensor and have a high malfunction rate. About 30,000 firefighters were dispatched to the scene as a result. Malfunctions of fire detectors are divided into actual reports that do not detect fire and non-fire reports that operate in situations similar to fire. Composite detectors are sometimes used to compensate for the shortcomings of a single sensor, but the number of detectors is doubled and it is impossible to accurately determine the location of a fire. This is happening repeatedly. On the other hand, in order to reduce the false positive rate of fire detectors, several types of detectors are integrated and each detector detects a fire and can reduce the false positive rate problem when a fire is determined. In the case of installation and operation, there is a problem that various types of detectors must be distributed and managed, and the system member that recognizes or analyzes data output from the detectors and effectively propagates the occurrence of a fire in a timely manner is a problem.

Performance tests can be requested and used as update information, and various services can be provided based on the collected data for determining whether the multi-sensor fusion detector is operating or not.

There is an advantage in that it is possible to solve problems such as difficulties in maintenance and inspection, accident prevention and analysis of causes in case of accidents, and high system installation costs in the case of network-connected fire/gas detectors with a relatively simple configuration.
