The beneficial effects of the utility model are: the utility model has adopted the intelligent trouble that is independent of outside teleseme control mainboard to detect the diagnosis plate, this intelligent trouble detects the duty that the diagnosis plate can detect each parts in traffic signal controlling machine in real time, comprise and detect whether abnormal of light fixture drive plate, the detection signal machine is controlled whether abnormal of mainboard, detects whether abnormal and the phase conflicts situation is detected of DETECTION OF TRAFFIC PARAMETERS plate.When certain or some parts being detected and break down, generate failure code and also show.Therefore, the traffic signal controlling machine with intelligent trouble diagnosis function described in the utility model can effectively carry out Real-Time Monitoring to traffic signal controlling machine, is convenient to the staff traffic control situation is understood in real time and processed.
Description of drawings
In order to make the purpose of this utility model, technical scheme and beneficial effect clearer, the invention provides following accompanying drawing and describe:
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
Fig. 1 is the structural representation with traffic signal controlling machine of intelligent trouble diagnosis function described in the utility model, comprises that a block signal machine is controlled mainboard, communication module, polylith DETECTION OF TRAFFIC PARAMETERS plate, polylith light fixture drive plate and an intelligent trouble detect the diagnosis plate; Intelligent trouble detects the diagnosis plate and comprises level switch module, data analysis module, communication interface and display interface.
Described communication module is used for realizing communicating by letter of traffic signal controlling machine and remote control center, comprises: the command information that the control information of described teleseme control mainboard is sent to remote control center, receiving remote control terminal.
When traffic signal controlling machine is in running order, the DETECTION OF TRAFFIC PARAMETERS plate can detect every traffic parameter at crossing, these parameters include but not limited to the speed of a motor vehicle, vehicle flowrate and the time occupancy in each track, and testing result is sent to teleseme control mainboard.Teleseme is analyzed result after controlling the testing result that mainboard receives each DETECTION OF TRAFFIC PARAMETERS plate, and according to analysis result to light fixture drive plate output control signal, control the action of light fixture drive plate; Simultaneously, teleseme control mainboard also is sent to intelligent trouble with the control signal of exporting and detects the data analysis module of diagnosing in plate.
