Brief description of the drawings
Fig. 1 is the general principle block diagram for the rectification cabinet controller that the present embodiment provides.
Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it is to be understood that reading the content of the utility model instruction
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
Fig. 1 is the general principle block diagram for the rectification cabinet controller that the present embodiment provides, and described rectification cabinet controller includes
Arm processor, the output end of arm processor connection digital quantity input module, the input and analog quantity of digital output module
The output end of input module, arm processor are also connected with alarm.
In the present embodiment, the input of 10 railway digital amounts of configuration, the output of 10 railway digital amounts and 4 road analog inputs.
Output end of the contactor of four groups of blower fans in rectifier cabinet respectively with digital output module all the way is connected, and demagnetization is opened
Output ends of the Q also with digital output module all the way is closed to be connected.A rotation sensor is equipped with each blower fan, it is each to rotate sensing
Input of the device respectively with digital quantity input module all the way is connected.
Wind-warm syndrome detection sensor is in rectifier cabinet, wind-warm syndrome detection sensor and the input of Analog input mModule all the way
Connection.
Arm processor is connected by Ethernet interface with host computer, and arm processor also passes through serial ports and outside display screen
Connection.
The groundwork process of rectification cabinet controller that the present embodiment provides is：Each rectifier cabinet sets a rectifier cabinet control
Device processed, when arm processor receives the conjunction degaussing switch order of host computer, arm processor will send 500ms pulse
Signal, degaussing switch Q is closed, while close the first contactor of the first blower fan.After 7s, the feedback letter of detection the first blower fan rotation
Number DI1, if can't detect the feedback signal of the first blower fan rotation, now think the first fan trouble, separate the first wind automatically
The first contactor of machine.The second contactor of the blower fan of adhesive second after 2s, the second blower fan of control is powered, after 7s, detects the second wind
The feedback signal DI2 that machine rotates, if can't detect the feedback signal of the second blower fan rotation, illustrate the second blower fan also failure.With
This analogizes, and is sequentially switched to the 3rd blower fan and four fan device, if Quan Buzhuan, by warning draught fan failure.
