Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, system of the present invention comprises: controlling center and a plurality of control sub-station.Controlling center is a control center, and each control sub-station is controlled corresponding one group of direction board.Described one group of direction board comprises right road direction board and left road direction board.Each direction board comprises normal traffic pilot lamp, left traffic pilot lamp, right traffic pilot lamp and malfunction indicator lamp.
Adopt the RS485 communication modes between controlling center and control sub-station.The controlling center capacity: 15 groups of control sub-stations of maximum support, use toggle switch to select the control capacity of controlling center correspondence.
Controlling center comprises four-way switch, No. four relays and a 4-bit DIP switch; Control sub-station comprises No. eight relays and No. eight relays pilot lamp of returning to school.
After powering on and move, controlling center just detects the state of four-way switch in real time, the normal traffic pilot lamp of the corresponding control of four-way switch, left traffic pilot lamp, right traffic pilot lamp and malfunction indicator lamp.Four-way switch connects the shift knob of controller panel, when the shift knob of panel touches, controlling center received the corresponding button signal and sent corresponding control command by the RS485 bus to control sub-station this moment, each control sub-station receives the control command of controlling center and resolves control command, the state of the corresponding track direction board that the output control sub-station is controlled, control sub-station reads the state of returning to school and the storage of controlling center relay output in real time, controlling center sends after this control command just with the taking turn relay that the reads control sub-station state of returning to school regularly at interval in 10 seconds, so that the correctness that the inquiry control sub-station is carried out, when the state of returning to school and the virtual condition of finding certain control sub-station have not simultaneously, controlling center is just reported to the police by relay control fault pilot lamp, up to reading the correct state of returning to school of control sub-station.
As shown in Figure 2, controlling center flow process of the present invention is as follows:
Step 1: controlling center detects and has or not control signal, if do not have, returns step 1, continues to detect; If have, enter into step 2;
Step 2: controlling center is resolved control command, forwards step 3 to;
Wherein, the described controlling center of step 2 is resolved control command, and the concrete practice is as follows:
Step 3: controlling center forwards step 4 to by the RS485 transmitting control commands;
Step 4: each control sub-station receives the control command of controlling center, responds and carry out this control command, i.e. the actuating of relay of control sub-station.Get back to step 1.
Fig. 3 is a controlling center panel synoptic diagram, comprises connection terminal 1, connection terminal 2, connection terminal 3 and toggle switch.Each connection terminal and toggle switch are defined as:
(1) connection terminal 1
(2) connection terminal 2
(3) connection terminal 3
