Description
Technical Field
The invention belongs to the technical field of safety monitoring, and relates to a control method of a gas alarm and shutoff device.
Background
At present, in order to guarantee the safety of gas, a domestic policy of coming out installs a gas safety intelligent detection device, and the function of the gas safety intelligent detection device is used for gas and is detected for a gas pipeline in real time. The intelligent judgment is carried out on the gas due to use or pipeline leakage, the gas valve in the gas meter is closed due to interference, information is uploaded to a management department, a user and a manager are reminded to predict in advance and process in time, and accidents caused by the gas leakage are avoided. The existing method for closing the valve by a gas alarm is characterized in that the gas alarm is connected with a pipeline gas valve in a wired mode to control and close the pipeline gas valve. And secondly, the gas pipeline valve is controlled to be closed through triggering NB-lot narrowband internet of things communication of the gas alarm. And thirdly, triggering Bluetooth communication through a gas alarm to close an electric control valve in the gas meter. The first gas alarm end needs to be connected with a 220V power supply for power supply, and is in wired transmission numerical control, high in material cost and construction cost, and the active electric control valve for pipeline installation has potential safety hazards and cannot upload information. The second gas alarm end also needs 220V power supply, wireless NB-lot transmission numerical control, material cost is higher, installation and construction cost is high, and the active electric control valve of pipeline installation has the potential safety hazard, can upload information. The third gas alarm end also needs to be connected with a 220V power supply for power supply, wireless Bluetooth communication is realized, the receiving end needs to be supplied with power by an independent battery, the power consumption is high, the material cost is higher, if the Bluetooth module is connected with a battery in the gas meter, power cannot be supplied for a long time, so that the normal work of the gas meter is prevented from being influenced, and information can be uploaded through NB-lot in the gas meter. The three methods for solving the problem that the gas valve is closed by gas alarm are all derived from information judgment of an alarm end, compensation judgment is not added, the solving method is high in material cost and construction cost, the pipeline installation valve has connection hidden danger, data uploading is limited, gas operation and management are not facilitated, and the method is not the optimal solution.
Disclosure of Invention
The invention aims to solve the technical problem of disclosing a safety control method of a gas alarm and shutoff device, which can utilize a battery as a power supply to supply power, thereby improving the safety and reliability of the gas alarm and shutoff.
The technical scheme for solving the technical problems is that a gas alarm and a shutoff device are formed by a gas alarm and an Internet of things gas meter, the gas alarm is a signal transmitting end, a temperature sensor, a CPU and a radio frequency module are arranged in the gas alarm, the scene temperature limit value, whether a system is normal or not, the electric quantity of a power supply battery and other states are judged, and then information is sent out in a wireless mode through the radio frequency module (independent battery power supply); the Internet of things gas meter is a signal receiving end, a receiving module receives the gas meter (self-powered battery), whether the gas condition is normal is calculated by adopting a sleep, awakening, detection, receiving and sleep circulating working mode, the judged gas condition is sent to an instruction gas meter receiving module, a valve is closed according to an instruction, whether data information is uploaded to a management platform is judged, the receiving module supplies power to an independent battery (3.7V/500 mAh/year) or takes a gas meter battery for auxiliary power supply, and the information is uploaded to the management platform through NB-lot in the meter.
In a cyclic working mode of sleeping, awakening, detecting, receiving and sleeping, the idle interval time between two adjacent data packets of a signal transmitting end and the idle interval time is less than the receiving time of a receiving end; the sending time of the signal transmitting end is longer than the receiving period of the receiving end, and the receiving period is the sum of the awakening time, the receiving time and the sleeping time.
The transmitting and receiving method can effectively save electric energy, thereby realizing an independent battery power supply mode, closing the gas under the condition of no power grid power supply and avoiding secondary accidents, and the transmitting and receiving method has the characteristics of low equipment and installation construction cost by adopting a wireless transmission mode, no danger hidden danger of a closed valve in the gas meter, convenient control and management of data uploading, accurate and complete received information, intelligence, low cost, low power consumption, high stability and large Internet of things.
Description of the drawings:
fig. 1 is a diagram of information transmission and reception according to the present invention.
The specific implementation mode is as follows:
the invention finally achieves the effects of minimizing power consumption and stabilizing reception in the modes of sleeping, awakening, receiving and sleeping.
When data is transmitted, one data packet is 1ms, the interval between every two adjacent data packets is 0.5ms, 10 data packets are transmitted by one group of data, the total transmission time is 14.5ms, the total time of every two adjacent data packets is 2.5ms, the receiving time when the data is received is longer than the total time of every two adjacent data packets, the receiving time is set to be 3ms, and at least one complete data packet can be received by the two data packets. The waking, receiving and sleeping are a data receiving period, the total time of the receiving period is less than the total sending time of a group of data, the receiving period is set to be 13.5ms, each group of data can be in the receiving period, and at least one complete data packet can be received without losing the data. The awakening time can be set to be 1ms, and the rest 9.5ms is in a sleep state, so that the ultra-low mode operation is realized, and the power consumption is reduced.
