Main control module 001 and auxiliary control module 002 all include power module, and power module includes working power supply and stand-by power supply, guarantees main control module 001 and auxiliary control module 002 normal power supply at ordinary times and emergency power supply.
The main control module 001 and the auxiliary control module 002 both adopt a 51-chip microcomputer as a control core, technicians use professional skills to program the 51-chip microcomputer into relevant programming languages, when the intelligent charging limit angle valve 1 is legally disassembled and assembled, firstly, liquefied gas in the liquefied gas steel cylinder 2 is ensured to be emptied, when the intelligent charging limit angle valve is disassembled, the technicians can use an inflation gun matched with a radio frequency identification unit to carry out identification and authentication, after the authentication is passed, the intelligent charging limit angle valve 1 is in a normal charging state, meanwhile, the main control module 001 sends a legal signal to the auxiliary control module 002, the auxiliary control module 002 controls the electromagnetic valve 5 to be in a circulation state, compressed air is filled into the intelligent charging limit angle valve 1 through the inflation gun, the compressed air sequentially enters the first flow passage and the second flow passage after passing through the intelligent charging limit angle valve 1, and when the air pressure reaches a certain value, the pneumatic piston 6 overcomes the resistance of the compression spring 13 and moves downwards under the action, and pushes a pair of adsorption boxes 7 to move downwards, and the limiting part of the adsorption box 7 gradually leaves the sliding hole and loses the limitation on the limiting magnetic ball 8, after the adsorption box 7 moves downwards to the state that a press switch 12 is contacted with a trigger rod 14 and is started, a micro power supply 11 is electrified to an electromagnet 10, the electromagnet 10 is electrified and magnetized, and then the limiting magnetic ball 8 is sucked from the anti-dismantling clamping groove and is mutually adsorbed, at the moment, the combined valve seat 3 does not have the limiting and anti-dismantling function on the anti-dismantling cylinder 4 any more, namely, a technician can adopt the existing means to dismantle the intelligent charging limiting angle valve 1 from the upper valve seat 301, during installation, the limiting magnetic ball 8 is adsorbed by the electromagnet 10 by the same means, the description is not expanded, and finally, after the charging of the charging gun stops, because the limiting magnetic ball 8 is spherical, even if the magnetic attraction of the electromagnet 10 on the limiting magnetic ball 8 is very large, the electromagnet 10 and the limiting magnetic ball 8 can realize the relative sliding in the vertical direction, when the adsorption box 7 is pushed to rise to the triggering rod 14 under the elastic force of the compression spring 13 and the push switch 12 is not pushed any more, the micro power supply 11 is powered off to the electromagnet 10, and the limiting magnetic ball 8 is reset under the elastic force of the reset snap spring 9 to be clamped into the anti-disassembly clamping groove again to realize fixation after the magnetic attraction force is lost.
When illegal disassembly and assembly of a lawbreaker are encountered, two specific cases can be distinguished:
1. and (3) illegal violence dismounting: that is, lawless persons forcibly disassemble and assemble when lacking corresponding equipment and means, the liquefied gas steel cylinder 2 is scrapped due to the consequence, so that when illegal violence disassembly and assembly is performed, the pressure sensor 17 can inevitably detect large pressure change and send the pressure change to the auxiliary control module 002, the auxiliary control module 002 sends an illegal disassembly and assembly signal to the cloud server 004 through the communication module 003, technicians at service points under the installation and wiring of the cloud server 004 can see and alarm on the spot, and the lawless persons can be prevented from continuing violence disassembly and assembly.
2. And (3) illegal and reasonable disassembly and assembly: that is, lawless persons have corresponding devices and means to detach the intelligent charging limiting angle valve 1 and the anti-detaching cylinder 4 without destroying the liquefied gas steel cylinder 2 and then recover the liquefied gas steel cylinder 2, but the auxiliary control module 002 does not control the solenoid valve 5 to be in a circulation state when not receiving the legal request of the main control module 001, that is, even if lawless persons want to recycle the liquefied gas steel cylinder 2 without damaging the liquefied gas steel cylinder 2, the use of the liquefied gas steel cylinder 2 can be realized only under the cooperation of the intelligent charging limiting angle valve 1 by using the second anti-detaching component as a last barrier, and when the lawless persons want to move the liquefied gas steel cylinder 2, the GPS positioning chip 18 in the solenoid valve 5 can also send the position information to the cloud server 004 in real time, and finally, the position information is tracked by offline technical personnel or police.
Therefore, no matter any one of the situations occurs, lawless persons cannot easily achieve the effect, tight protection on the liquefied gas steel cylinder 2 can be achieved, loss of the liquefied gas steel cylinder 2 is reduced, the internet of things technology can be applied to the traditional liquefied gas industry, informatization transformation of the industry is achieved, the industry management level is improved, meanwhile, the liquefied gas steel cylinder is effectively prevented from being illegally dismantled by the lawless persons to cause loss of the steel cylinder, further, the possibility that the liquefied gas market is disturbed and life and property safety of people is threatened occurs is achieved, safe use of the liquefied gas steel cylinder is improved on the basis of achieving intelligent charging limiting, and safe liquefied gas is provided for the market and people.
The foregoing is only a preferred embodiment of the present invention; the scope of the invention is not limited thereto. Any person skilled in the art should be able to cover the technical scope of the present invention by equivalent or modified solutions and modifications within the technical scope of the present invention.
