Valve intelligent management control system based on internet of things

Abstract

The invention discloses a valve intelligent management control system based on internet of things. The valve intelligent management control system comprises a plurality of valves, a system server anda mobile terminal, wherein the valves comprise a control unit and a communication unit, the control unit is connected with an alarm module, a first driving module and a second driving module correspondingly, the communication unit is connected with a valve state detection unit and a lock state detection unit correspondingly and is connected with the system server, and the mobile terminal is connected with the system server and the control unit correspondingly. The valve intelligent management control system based on the internet of things has the advantages that states of the valves and valvelocks can be monitored and controlled simultaneously, managers are made to master state information of the valves and locks comprehensively, changing of structures of existing valves is not needed, the locks are additionally installed on the basis of the existing valves directly, and the valve total cost is effectively reduced.

Description

technical field [0001] The invention relates to a valve management and control system, in particular to an intelligent valve management and control system based on the Internet of Things. Background technique [0002] In the water conservancy and hydropower industry, hundreds of valves of various forms are needed. Valves are pipeline accessories used to open and close pipelines and control flow direction. Valves are directly connected to pipelines. The existing status of traditional valves cannot be monitored. , when the valve is abnormal and cannot be reminded in time, manual statistics and manual switching are required. When the number of valves is large, it is easy to make mistakes. The switching of some larger valves is generally controlled by the valve handwheel. The valve handwheel needs to be manually rotated by the staff. Some important installation occasions need to use locks to lock the valve to prevent idlers from opening and closing the valve by turning the valve...

[0002] In the water conservancy and hydropower industry, hundreds of valves of various forms are needed. Valves are pipeline accessories used to open and close pipelines and control flow direction. Valves are directly connected to pipelines. The existing status of traditional valves cannot be monitored. , when the valve is abnormal and cannot be reminded in time, manual statistics and manual switching are required. When the number of valves is large, it is easy to make mistakes. The switching of some larger valves is generally controlled by the valve handwheel. The valve handwheel needs to be manually rotated by the staff. Some important installation occasions need to use locks to lock the valve to prevent idlers from opening and closing the valve by turning the valve handwheel by mistake, causing unnecessary financial losses and even safety accidents

[0003] On the road towards automation, valve denso is already a relatively common technology. The opening and closing of valves can be controlled remotely through the control system. However, for valves with locks, denso valves still inevitably need Open and close the valve on site. The valve lock is nothing more than the traditional mechanical lock using a key to unlock and the current electronic lock. The advantage of the mechanical lock is that it is cheap and the unlocking method is stable. However, for some valves, the quantity For many water conservancy and hydropower enterprises, it often happens that the operation and maintenance operators carry a tool bag with a pile of heavy chain locks, metal padlocks and safety signs in the bag, and register the metal one by one when operating in the underground factory. Number the keys of the padlock, and carefully put these keys back into the "second-class key cabinet" immediately after the operation is completed. The convenience of the lock switch is low, time-consuming and laborious

The electronic lock is an electronic product that controls the circuit or chip work through password input, thereby controlling the closing of the mechanical switch, and completing the tasks of unlocking and locking. Although it overcomes the disadvantages of less passwords and poor convenience of use in mechanical coded locks, both fingerprint coded locks and digital coded locks require the cooperation of professional processing chips and sensors to achieve switch requirements. The high cost is not suitable for pumped storage power plants and other applicable occasions with hundreds of valves
