Problems solved by technology
However, the gas company removes the gas alarm from the user's home and sends it to the quality inspection department for quality inspection. After passing the quality inspection, it needs to be installed in the user's home again, and the quality inspection operation is performed once a year, which leads to the gas company's lack of control over the gas alarm. Quality inspection consumes a lot of manpower and material resources
In addition, the gas alarm is offline and has poor real-time performance

Embodiment approach
[0050] In this solution, the learning of historical data is performed by the server of the gas enterprise, and the gas alarm actively or passively obtains the optimized calibration model from the server of the gas enterprise. In one embodiment, the gas enterprise server can learn from the historical data uploaded by each gas alarm, and the optimized calibration model is only used for the gas alarm. In another embodiment, since the gas enterprise server will receive the historical data uploaded by each gas alarm, when the gas enterprise server optimizes the calibration model according to the historical data, it can be based on all the gas alarms connected to it. The uploaded historical data is used to learn and optimize the calibration model. The optimized calibration model can be used by all gas alarms, which can reduce the calculation load of the gas server. Furthermore, in another embodiment, since the gas enterprise server will receive the historical data uploaded by each g...

The invention relates to an online self-calibration gas alarm device and a calibration method thereof. The gas alarm device comprises a gas detection unit, a control unit, an alarm body, a control unit, a communication module and a self-calibration module. The control unit communicates with a gas enterprise server through the communication module and acquires a calibration coefficient or a calibration model from the gas enterprise server; and the self-calibration module carries out automatic calibration according to the calibration coefficient or the calibration model. According to the invention, the gas alarm device can communicate with the gas enterprise server to obtain the calibration coefficient and automatic calibration is carried out to realize online automatic calibration, so thatthe gas alarm device does not need to be dismounted and mounted again an thus the manpower and material resources are greatly reduced and the labor cost needed by calibration is lowered.
Description
technical field [0001] The invention relates to the technical field of gas, in particular to an online self-calibration gas alarm and a calibration method thereof. Background technique [0002] In urban residential quarters, most families use natural gas, and the gas company will also install gas alarms in the homes. When gas leaks, the alarm will be triggered to alarm to ensure the safety of people's lives and property. In order to ensure the safe use of gas, the "Measurement Law" stipulates that gas alarms must be sent to the quality inspection department for annual inspection every year. However, the gas company removes the gas alarm from the user's home and sends it to the quality inspection department for quality inspection. After passing the quality inspection, it needs to be installed in the user's home again, and the quality inspection operation is performed once a year, which leads to the gas company's lack of control over the gas alarm. Quality inspection consumes...
