A kind of independent yellow control device that dodges of teleseme; Comprise first control chip; Its output terminal links to each other the output termination amber light L of independent yellow sudden strain of a muscle driving circuit with the input end of second control chip of signal lamp driver module 2, the independent yellow input end that dodges driving circuit respectively.The described independent yellow driving circuit that dodges adopts bidirectional triode thyristor BTA1, and the one of which end is through amber light L connecting to neutral line N, the other end line L that starts to exchange fire, and the output terminal of control termination first control chip of bidirectional triode thyristor BTA1, as shown in Figure 1.
As shown in Figure 1; The independent yellow teleseme that dodges control device with teleseme; Comprise teleseme main control module 1, signal lamp driver module 2 and the independent yellow control device 3 that dodges, between second control chip of teleseme main control module 1, signal lamp driver module 2, independent yellow first control chip that dodges control device 3 through the data communication bus communication.Independent yellow other functional module co-ordinations of dodging control device 3 and teleseme can separating signal machine main control module 1 and signal lamp driver module 2, signal lamp is carried out Huang dodge and control.
As shown in Figure 1, described signal lamp driver module 2 comprises second control chip, and the output terminal of second control chip links to each other with the input end of driving circuit, and the output terminal of driving circuit links to each other with amber light L.Described driving circuit adopts bidirectional triode thyristor BTA2, and the one of which end is through amber light L connecting to neutral line N, the other end line L that starts to exchange fire, the output terminal of control termination second control chip of bidirectional triode thyristor BTA2.The output terminal of described driving circuit links to each other with red light, green light respectively, and signal lamp driver module 2 is a driver module red, yellow, green light.A teleseme is controlled a plurality of driver modules; A driver module can only be controlled limited red, yellow, green light, and under normal conditions, a driver module can be controlled 4 red, yellow, green lights; A crossing has 16 reddish yellows green usually; 4 driver modules just, when any driver module broke down, the independent yellow control device 3 that dodges all moved.
Below in conjunction with Fig. 1 the present invention is further described.
The independent yellow control device 3 that dodges need be when teleseme main control module 1 and signal lamp driver module 2 faults, the control of taking over signal lamp, and this requires independent yellow sudden strain of a muscle control device 3 to have three functions:
1, have monitoring function, can pilot signal machine main control module 1 with signal lamp driver module 2, when they can't be worked, the independent yellow control device 3 that dodges can be learnt automatically, thereby get into independent yellow sudden strain of a muscle state;
2, the function that has 2 work of stop light driver module; When teleseme main control module 1 or certain signal lamp driver module 2 fault; The independent yellow control device 3 that dodges is taken over signal lamp driving power; Get into independent yellow sudden strain of a muscle state, other signal lamp driver modules 2 of going back operate as normal must quit work, otherwise it is chaotic to cause signal lamp to drive;
3, the independent yellow control device 3 that dodges can carry out light on and off work by all amber light L of cyclic drive belisha beacon when getting into independent yellow sudden strain of a muscle state, and the cycle is about 1 second, the light on and off time half and half.
For the independent yellow teleseme that dodges control device 3 is installed, must be data bus formula framework teleseme, promptly teleseme main control module 1 is controlled each drive plate and is carried out work through bus and each drive plate communication, and independent yellow sudden strain of a muscle control device 3 is also in the incoming communication bus.
During teleseme work, receive the return data that issues data and each drive plate of teleseme main control module 1 always.If do not receive the data that issue of teleseme main control module 1; Or the return data of signal lamp driver module 2; Just think teleseme main control module 1 fault or certain signal lamp driver module 2 fault, the independent yellow control device 3 that dodges begins to take over the signal lamp control, gets into independent yellow sudden strain of a muscle state.
After getting into independent yellow sudden strain of a muscle state, the independent yellow control device 3 that dodges says the word for all signal lamp driver modules 2, requires signal lamp driver module 2 to stop the driving work to signal lamp.Owing to possibly be the yellow arcing fault of independence that the bus communication fault of certain signal lamp driver module 2 causes; So can't send order for signal lamp driver module 2 through bus; Must be through the enable of other I/O signal as 2 work of signal lamp driver module, the independent yellow control module 3 of dodging quits work through controlling this pin command signal lamp driver module 2.
After getting into independent yellow sudden strain of a muscle state; Independent yellow first control chip that dodges control device 3 begins to carry out timework, the break-make of signal lamp is controlled signal lamp light on and off half and half second through the independent yellow driving circuit that dodges; Dodge because carry out Huang this moment; Red light and green light are not worked, so the independent yellow driving circuit that dodges only meets amber light L, need not red light and green light are controlled.Amber light L is driven by signal lamp driver module 2 when operate as normal; Drive by the independent yellow control device 3 that dodges during independent yellow sudden strain of a muscle state; So amber light L is driven by two devices; So the driving of two devices output should be attempted by on the amber light L, can only there be a device to carry out driving work in two same times of device.
In sum, this independent yellow 3 of control device that dodge is applicable to the teleseme of teleseme main control module 1 through data bus control signal lamp driver module 2 types, and data bus must insert by multiple spot, such as the RS485 bus.During operate as normal, teleseme main control module 1 sends order data and gives signal lamp driver module 2, and signal lamp driver module 2 drives all signal lamp work.Insert bus, the order data of monitoring signal machine main control module 1, and the reply data of signal lamp driver module 2 to the independent yellow communication interface that dodges control device 3.If teleseme main control module 1 damages or signal lamp driver module 2 damages; 3 monitorings of independent yellow sudden strain of a muscle control device are less than these data; The independent yellow control device 3 that dodges passes through an I/O port output command, after all drive plates receive this I/O port command, and the driving work of stop light; The independent yellow control device 3 that dodges receives the amber light control, and individual drive amber light L carries out Huang and dodges control.
