Intelligent ventilation operation system based on gas meter and remote intelligent control method

Abstract

The invention relates to an intelligent ventilation operation system based on a gas meter and a method for achieving remote intelligent control. The system comprises a PC, upper computer control software, a ventilation operation frame and a to-be-tested gas meter. The PC and the upper computer control software are used for generating and issuing a ventilation test flow configuration instruction and a remote control instruction; the ventilation operation frame comprises a ventilation valve switch control main board corresponding to the gas meter to be tested; the ventilation valve switches on and off the control mainboard; and the controller is used for receiving and analyzing the flow configuration instruction and the remote control instruction, controlling the on-off of the correspondingventilation valve switch on the ventilation operation frame according to the remote control instruction, and testing the ventilation operation flow of the corresponding to-be-tested gas meter according to the flow configuration instruction. By adopting the system and the method provided by the invention, the manpower is saved, and the accuracy of the test process is also improved.

Description

technical field [0001] The invention relates to the technical field of program control, in particular to an intelligent ventilation operation system based on a gas meter and a method for realizing remote intelligent control. Background technique [0002] In the existing gas meter test process, the gas meter needs to be ventilated first, and then its stability and durability, as well as the accuracy of electromechanical errors, should be tested. The gas meter ventilation operating device used mainly includes blower, ventilation pipe, ventilation valve switch and other components, which are used to simulate gas meter ventilation counting and performance testing. Among them, the ventilation valve switch specifically adopts a motor valve, and the motor valve is a valve driven by a motor, which is used to control the on-off switch of the gas flow, and the gas flow rate is controlled according to the length of time the valve is energized. However, the current ventilation operatio...

AI Technical Summary

Problems solved by technology

[0003] 1) Manual on-site operation is required, but sometimes it needs to run for dozens or even hundreds of hours, and it ends when the tester is inconvenient to close the valve or the ventilation operation requires a process test, and the test process is difficult to contact

[0004] 2) On-site operation is not only difficult to implement, but also wastes the time of the testers, and the long-term running noise will also cause damage to the hearing of the testers

[0005] 3) Manual control of the ventilation operation process, there is a large process error
