Natural gas alarm based on NB-IoT technology

Abstract

The invention provides a natural gas alarm based on a NB-IoT technology. The natural gas alarm comprises an alarm electric control valve and an alarm system. The alarm system comprises a power supplymodule, a semiconductor sensor, an acousto-optical module, a NB-IoT wireless module and a microprocessor. The microprocessor compares the natural gas concentration data collected by the semiconductorsensor and the preset warning value. When the microprocessor determines that the natural gas concentration data collected by the semiconductor sensor exceeds the warning value, the acousto-optical module and the NB-IoT wireless module transmit the natural gas concentration data exceeding the warning value to a monitoring end. If the microprocessor cannot get the response from the monitoring terminal within the set time, the microprocessor sends a driving signal to the electric control valve, and the electric control valve is closed. The natural gas alarm provided by the invention has the advantages that the NB-IoT wireless module is used as a remote data transmission module, has the advantages of convenient networking and long service life, and is suitable for large-scale use; the naturalgas alarm is provided with the electric control valve which automatically blocks natural gas leakage; and the safety performance is higher.

Description

technical field [0001] The invention relates to an alarm, in particular to a natural gas alarm based on NB-IoT technology. Background technique [0002] At present, residential buildings, factories, and commercial buildings generally use natural gas as energy for cooking, heating, and hot water. Due to various reasons such as improper use, aging of natural gas pipelines and unqualified gas cookers, natural gas leakage often occurs. If this leakage cannot be detected in time, it will easily cause huge property losses and casualties. Therefore, natural gas users generally install natural gas alarms to prevent natural gas leakage. Existing natural gas alarms generally use microprocessors to connect sensor modules and alarm modules, and determine whether there are potential safety hazards by calculating data from the sensor modules. The module performs alarm and uses GSM card or ZigBee technology for remote alarm. Due to the high power consumption of the GSM card or ZigBee wire...

Due to various reasons such as improper use, aging of natural gas pipelines and unqualified gas cookers, natural gas leakage often occurs. If this leakage cannot be discovered in time, it will easily cause huge property losses and casualties.

Therefore, natural gas users generally install natural gas alarms to prevent natural gas leakage. Existing natural gas alarms generally use microprocessors to connect sensor modules and alarm modules, and determine whether there are potential safety hazards by calculating data from the sensor modules. The module performs alarm and uses GSM card or ZigBee technology for remote alarm. Due to the high power consumption of the GSM card or ZigBee wireless transmission module, the short service life, the high cost of data network upload, it is not conducive to large-scale use, and there is no one on site or the personnel are unconscious. In the case of a natural gas leak, it cannot be dealt with in time, nor can it be notified to others to deal with the scene in time, and it is impossible to effectively prevent the occurrence of natural gas leakage safety accidents
