Problems solved by technology

At present, the intelligent controller of the drainage device has little display information, simple communication, and low precision. The human-machine interface of the drainage device is simple, and the drainage control is simple. Generally, it is qualitative drainage, and the drainage flow cannot be automatically adjusted. The accuracy is not high and reliable. poor sex

Embodiment Construction

[0019] Such as figure 1 As shown, an automatic drainage device includes an intelligent controller, a loop control module, and a drainage branch; the intelligent controller is connected to an intelligent sensor for collecting stray current data, a loop control module, and an integrated automation center through a field bus. It is connected with the microcomputer management system through the Ethernet interface, and the loop control module is connected with the drainage branch. The intelligent controller uploads the stray current related data collected by the smart sensor to the microcomputer management system through the Ethernet; completes the signal transmission conversion between the smart sensor and the integrated automation system through the field bus, and performs real-time monitoring of the collected stray current related data; The operation of the drainage branch is controlled by the loop control module. When the drainage branch is working, the loop control module real...

Abstract

The invention discloses an automatic drainage device and a control method thereof, which relate to the field of the monitoring and protection of stray current in subway systems. The automatic drainage device comprises an intelligent controller, a loop control module and drainage branches, wherein the intelligent controller is connected with an intelligent sensor, the loop control module and a comprehensive automatic center respectively through a field bus, and is connected with a microcomputer management system through an Ethernet interface. The control method comprises the following steps that: the intelligent controller communicates with the intelligent sensor through the field bus so as to acquire stray current related data, uploads the stray current related data which is acquired by the intelligent sensor to the microcomputer management system through the Ethernet, and accomplishes signal transmission conversion between the intelligent sensor and the comprehensive automation system through the field bus; the acquired stray current related data is monitored in real time; and the acquired stray current related data is analyzed, and whether to perform drainage control on the processed data or not is judged according to the processed data. The invention has the advantages that: the method is high in real-time performance, information transmission stability is achieved, and the automatic drainage device and the control method thereof can be widely applied to stray current corrosion monitoring and protection systems for subways.

Description

technical field [0001] The invention relates to the field of monitoring and protection of stray currents in subway systems, in particular to an automatic drainage device and a control method thereof. Background technique [0002] Urban rail transit adopts the DC traction power supply method of running rail return, which will inevitably generate stray current. Due to the effect of stray current, it will cause electrolytic corrosion of buried metal, which is not only fast, but also often appears on the metal surface. Deep perforation corrosion with catastrophic consequences. Therefore, it is necessary to monitor the stray current in real time and protect the buried metal. [0003] At present, the monitoring and protection of stray currents in subways are generally carried out separately. Data related to stray currents are collected through sensors and uploaded to the intelligent controller. The intelligent controller communicates with the monitoring center. The monitoring cen...
