Description
Technical field
The utility model relates to a kind of control system of urban track traffic, specifically a kind of control system based on PLC orbit traffic direct current traction rectifier.
Background technology
In today that Urban Rail Transit Development has a extensive future, a lot of main equipment all needs to possess real-time monitoring, signals collecting and information and the function such as to upload.Designing quick, stable, a reliable control system is one of basic demand of Urban Railway Substation automated system, is the prerequisite realizing the urban transportation operational management function.Along with the development fast of urban track traffic automated system, need reliable control system equally, but control system of the prior art due to vibrational power flow unreasonable, make that its integrated level is poor, monitoring reliability can not be guaranteed, the requirement of Urban Railway Substation automated system can not be met.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of control system of rational in infrastructure, Monitoring Data is accurate, reliability is high PLC orbit traffic direct current traction rectifier.
In order to solve the problems of the technologies described above, the control system of PLC orbit traffic direct current traction rectifier of the present utility model, comprise PLC module, PLC module connection status signal input module, status signal output module, temperature collect module and display unit, other one end of status signal load module is connected with electric power system unit, and temperature collect module is connected with temperature sensor.
Described temperature sensor is set to two or more, and each temperature sensor is all connected on temperature collect module.
Described PLC module also connects PSCADA system.
After adopting above-mentioned structure, due to PLC module and the status signal load module be connected with PLC module, status signal output module, the temperature collect module of setting, temperature sensors etc. can settling signal collection, information be uploaded and real-time monitoring to equipment, its vibrational power flow is reasonable, signals collecting precision is high, reliability is high, good stability, meets the requirement of Urban Rail Transit Development.
Accompanying drawing explanation
Fig. 1 is the theory diagram of the control system of the utility model PLC orbit traffic direct current traction rectifier.
Embodiment
Below in conjunction with the drawings and specific embodiments, to the control system of PLC orbit traffic direct current traction rectifier of the present utility model, comprise PLC module, PLC module connection status signal input module, status signal output module, temperature collect module and display unit, other one end of described status signal load module is connected with electric power system unit, temperature collect module is connected with temperature sensor, temperature sensor is set to two or more, and each temperature sensor is all connected on temperature collect module.Communicate to the real-time monitoring of rectifier internal signal by PLC with display unit, real-time status signal can be shown on screen, comprise the state of each fuse, the state of reporting to the police, the state of tripping operation, real time temperature, failure message etc., uploading of information is completed: adopt MODBUS-RTU agreement local information to be uploaded to backstage PSCADA system, realize remote real-time monitoring by PLC module.Its principle of work is as follows:
By the digital quantity input port of PLC, state signal collecting is inner to PLC, carry out signal transacting and logical operation fast by the CPU of PLC; Combined by all fault-signals, all trip signal combinations, the combination of diode protection fuse alerting signal and trip signal, is then exported status signal by PLC digital output mouth; The analog quantity input of PLC can be used for gathering voltage, current signal, and the collection of temperature signal also needs temperature collect module to be translated into voltage signal to be gathered by PLC again, and carries out signal transacting in PLC inside to it; Adopt 5.7 cun of large color screen display units to monitor in real time all signals, by Siemens PPI agreement and plc communication, realize data sharing.Screen can be seen the state of all fuse signals, the real time temperature of rectifier, fault-signal, trip signal, failure logging information etc., PLC adopts MODBUS-RTU agreement, combine with backstage and control PSCADA system and communicate, local information is all uploaded, realizes remote real-time monitoring.
