Specific embodiment
Understand for the ease of those of ordinary skill in the art and implement the present invention, below in conjunction with the accompanying drawings and embodiment is to this
It is bright to be described in further detail, it will be appreciated that enforcement example described herein is merely to illustrate and explains the present invention, not
For limiting the present invention.
Because existing semaphore is in accordance with GB GB25280-2010, so the output of semaphore is all band output detection
Function.It is to report to the police to be intended to semaphore in unloaded output.We load according to this Simulations one and give semaphore output,
By gathering to signal output level, correspondence respective channel, with bus mode（RS485 or CAN）Transmit to Traffic signal post
The output board hung.So output board is taken parsing to make feedback and is judged for communication signal.So as to directly on Traffic signal post
Control signal lamp.This relates to following several technical indicators：
1., dual bus is controlled simultaneously.It is intended to RS485 and CAN to be selected in other words based on CAN according to user, 485 communications are simply auxiliary
Effect is helped, CAN failures are prevented.When CAN communication, 485 forbid.
2., export detection to report.Bus control unit（BCU）Output board is for directly control traffic lights.When lamp whether
Bus control unit control panel will normally be reported.Control panel one end is to connect semaphore to export and simulate an output.When certain
Road bus control unit finds lamp failure, can inform bus control unit control unit.Control unit will break simulation to semaphore
Output this part circuit.The original semaphore in crossing is made by zero load, while failure also oneself can be found to do degradation process.
3. the communication-type countdown interface of GB, is met.If bus communication control is all taken at crossing, then for crossing
Count-down device if communication-type or trigger-type, then bus control unit output board must also support such interface.Cause
There was only four lines in well casing for bus control unit.
4., communication speed is fast, and communication distance is remote.It can be to reach 300 meters of distance under 9600bps that RS485 is communicated.But
Frame and signal has 10ms delay times, due to human eye it is imperceptible, it is possible to allow time delay.And CAN exists
300 meters remote can be transmitted under 50Kbps baud rates, but communication time delay is less than 1ms.So scheme is taken based on CAN,
Supplemented by RS485.
5., main control chip collection and operating efficiency are fast；
This programme main control chip adopts STM32F103ZET6.The chip operation speed can reach 72Mhz.And using embedded
System, can quickly solve parallel data acquisition and processing function.
6., threading is few, transformation Bu Po roads, simple low cost of constructing；
This scheme walks four lines, or 5 for new crossing only needs to well casing（Standby one）, this addresses the problem and be constructed into
This.This four lines are respectively AC220V power lines（2）, with connection（Bus 2）.Output board is directly hung on signal lamp.
And main control unit is together with signal cabinet placement.By well casing 2 with power line, to signal lamp and output board powered operation,
Another both threads are communicated to output board, inform running status.
7., any a semaphore on the market is met；
Such problem essentially consists in all faulty reporting functions of all semaphores and degradation is processed, for the letter of interconnection type
Number machine all can report backstage and the process that degrades using failure.For single-point type all only takes degradation to process.It is all due to meet
Semaphore, so program can not be done according to datagram protocol on each signal trouble processing.Process aspect can only be simulation side
Face, i.e., to semaphore take load disconnect, that is, do not give semaphore output, such semaphore also can self-inspection know.
Based on above present situation, and technical problem, Fig. 2 and Fig. 3 is asked for an interview, a kind of bus transmission model control that the present invention is provided
Traffic signal lamp system, including semaphore and some bus control units (BCU)；If bus control unit by BCU input detection plate and
Dry BCU output boards composition, semaphore is connected with BCU inputs detection plate, and the traffic lights of all directions are equal（By phase-group）Match somebody with somebody
BCU output boards are equipped with, BCU input detection plates and some BCU output boards are connected by bus；BCU input detection plate simulations are negative
Carry to semaphore, detection signal machine state, then microprocessor processes judge, and are transferred to BCU with protocol mode by bus
Output board；Whether BCU output board analysis protocols, judge traffic lights in normal work, if be not at state, then report
BCU is input into detection plate, and BCU is input into detection plate according to reporting fault, makes break load output, and semaphore receives route failure report
Accuse, and respond.
The BCU inputs detection plate of the present embodiment connects semaphore output, and semaphore controls how many roads now, just connects how many road inspections
Survey to input detection plate, BCU inputs detection plate is placed in signal cabinet.Pipeline is walked using 4 lines for new crossing to connect
BCU output boards are connect, and for old crossing, cabling can be avoided, directly with former internal links line, select 4；Output board
