Description of drawings
Fig. 1 is a fundamental diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
The present invention includes microprocessor 1; Its working clock frequency reaches 60Mhz, and the US/OS-II real time operating system is adopted in software programming, constitutes the embedded controller of a high speed.
Vehicle detection input interface 2 is connected with microprocessor 1 input end; Vehicle detection technology relatively more commonly used at present has the toroid winding vehicle detection, infrared detection, detections of radar, Microwave Measurement, laser detection.The most commonly used is the toroid winding vehicle detection, and this detecting device basically all is that passive photoelectricity is isolated output.This design of Controller has 16 road photoelectricity to isolate the digital quantity input, and the output of 12V direct supply is provided simultaneously.Passive photoelectricity be can better be adapted to and the wagon detector of output and the vehicle detecting sensor of various dry contact output isolated; Because detecting input interface 2, this 16 road vehicles belongs to the photoelectricity isolation with controller core MCU fully; And each interface all is independently to import, so the vehicle detecting sensor of the also compatible 12V-24V output of controller.Design 16 road vehicles and detect input interface, can be good at adapting to the crossroad of two-way Four-Lane Road or the crossroad in unidirectional 4 tracks.
Red signal input interface 3 is connected with microprocessor 1 input end; Conventional traffic light signal all is that the 220V alternating current directly drives traffic lights.For compatible this 220V red signal, Acquisition Circuit also is directly to carry out the 220V alternating current to pacify and return capacitance decompression, rectification, filtering directly to detect.This detection mode is utilized the relay auxiliary node to connect low-voltage signal and is advanced acquisition controller after driving relay than conventional 220V alternating current, and perhaps directly adding easy DC power supplier carries out high voltage variable low pressure, and the mode of gathering is again compared.There is the action delay of relay in the relay conversion, and the action energising of general relay is moved less than 40ms, and transfers electric return action to extend less than 50ms.Though only how many influences the time delays less than 50ms can not cause to the capturing system that makes a dash across the red light.Yet in the work of high speed motion, these two times can constantly prolong variation along with the prolongation of relay working time.Have a strong impact on the stability of system; Use common stabilized voltage supply to carry out the processing that 220V changes low-voltage signal, have the phenomenon of this power on time-delay and power down time-delay equally.All there is a big capacitor filtering common stabilized voltage supply inside, adds the time-delay that time-delay that transformer (inductive load) causes just can reach 3s-5s.Handle though on software, can carry out the lead of this time-delay, yet from having lost the control requirement of synchronous acquisition in essence and fully.
When the present invention gathers red signal, only use peace to return the direct step-down of electric capacity, rectification to supply the collection of ARM7 microprocessor again.Be greatly improved on the picking rate, install and use more convenient reliably, realized the synchronous acquisition of crossing traffic light signal fully.
External light source detects input interface 4, is connected with microprocessor 1 input end; Consider that control main board is applied to electronic police light filling system at night, consider that from the angle of energy-conserving and environment-protective the present invention uses 10 A/D converter to carry out the external light source intensity detection, software set light filling parameter.Join and the time of making a dash across the red light is carried out the light filling at night.
The advantage of control bus of the present invention:
1, a pair of N structure:
Can connect a plurality of controllers of the present invention through a control bus, a pair of transmission line, the N collection plate, a plurality of signals of transmitted in both directions, this makes wiring simple, and construction period is short, and the low wiring of erected cost is easy.Only need to add if increase the road junction roadway increase, only need parallel being articulated to that new plate address is set on the cable, need not to set up new cable.
2, reliability is high:
The digital data transmission antijamming capability is strong, and precision is high, need not to adopt measure anti-interference and the raising precision, thereby has reduced cost.
3, controllable state:
The operator both can understand the working condition of field apparatus or on-the-spot camera in the pulpit; Also can adjust its parameter; Also measurable or trouble-shooting is in operator's remote monitoring and controllable state all the time, has improved reliability, controllability and the maintainability of system.
4, decentralised control:
Integrated camera light filling, capture control function, just can constitute control loop, realized decentralised control completely, improved reliability, autonomy and the dirigibility of system through on-the-spot red signal, wagon detector.
Electric police grasp shoot light filling system, the practical annular ground induction coil of vehicle detection inserts the vehicle monitoring device and detects in real time, and carries out the detection of red signal, and considering does not simultaneously need light filling to add the detection of external light source intensity daytime.On daytime, when vehicle made a dash across the red light through annular ground induction coil under the red signal, control panel output just triggered the high definition camera with regard to mouth and captures; At night, when vehicle made a dash across the red light through annular ground induction coil under the red signal, control panel output just triggered the high definition camera with regard to mouth and captures, and triggers the stroboscopic lamp light filling simultaneously.
Capture card signal output interface 7 is connected with microprocessor 1 output terminal; 16 road vehicles detection signals and the input of 8 road red light detection signals are input to inner 724IO Acquisition Circuit synchronously, with the output of 50 pin flat cable interfaces, supply the collection of 724IO capture card.The output of this interface is in order to consider that more present company's upper computer softwares still depend on 724 IO capture cards to the use of these signals.Backward, superseded stage that sort signal collection, use-pattern have belonged in the use of total system.50 pin flat cable signal limitations the distance (in the 1M) between industrial computer and the collection plate, system has also increased the cost of 724 IO cards, and requires front end must place industrial computer.Cause project construction greatly, the difficulty of maintenance.
The above only is a preferred implementation of the present invention; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the principle of the invention, can also make some improvement and retouching, these improvement and retouching also should be regarded as protection of the present invention.
