Embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
With reference to Fig. 1, be the process flow diagram of a kind of road monitoring method one embodiment of the present invention.
The crossing supervising device detects the traffic lights signal by radio port in the road monitoring method in the embodiment of the invention, for example: by wifi or bluetooth and other radio ports.When traffic lights signal indication red light was bright, the crossing supervising device is in treated shooting state, triggers when this moment, vehicle speeded through a red light line ball and takes.
Step S101, signal lamp red light are bright, send first switching signal by radio port to the crossing supervising device;
Wireless transmitter module acquired signal lamp on/off information is installed on the signal lamp, makes switching signal and be transmitted to the crossing supervising device by radio port.Radio port in the embodiment of the invention can be radio ports such as wifi or bluetooth.
Step S102, crossing supervising device switch to according to first switching signal and treat shooting state;
When the signal lamp red light was bright, the indication of first switching signal of transmission was in red light phase this moment, and the crossing supervising device switches to treats shooting state, and trigger the crossing supervising device and take this moment when vehicle speeds through a red light line ball.
Step S103, signal lamp red light go out, and send second switching signal by radio port to the crossing supervising device;
S101 is similar with step, and the wireless transmitter module on the signal lamp is made second switching signal and is transmitted to the crossing supervising device by radio port after collecting the relevant information that red light goes out.
Step S104, crossing supervising device switch to holding state according to second switching signal.
When the crossing supervising device received second switching signal that indication this moment, red light went out, the switch operating state was to holding state, even vehicle line ball crossing supervising device is not taken yet at this moment.
When switching by traffic lights generation signal lamp, the present invention sends switching signal to the crossing supervising device by radio port, make and need not connect up between crossing supervising device and the traffic lights, do not need to have saved the construction working amount and can not disturbed yet because of environmental problem by Video Detection yet.
Fig. 2 is the process flow diagram of a kind of another embodiment of road monitoring method of the present invention.
The corresponding embodiment of Fig. 1 can be applied in the monitoring of bicycle road, can adopt the embodiment of the invention to monitor when multilane is monitored.
Step S201, when the signal lamp red light is bright, send first switching signal carry the track sign to the crossing supervising device by radio port;
When described signal lamp is the multilane signal lamp, when arbitrary red light is bright, send first switching signal of carrying the track sign to the crossing supervising device by radio port; For example certain bar road comprises the craspedodrome and two tracks of turning left, and this moment, the Through Lane red light went out, and the left turn lane red light is bright; When the left turn lane red light is bright, send first switching signal of carrying the left turn lane sign to the crossing supervising device.
Step S202, crossing supervising device switch to according to first switching signal and treat shooting state;
The crossing supervising device switches to according to first switching signal of carrying the track sign and treats shooting state, takes when described track identifies the vehicle line ball in corresponding track.
The crossing supervising device switches to according to first switching signal of carrying the left turn lane sign and treats shooting state, and at this moment, the crossing supervising device is not taken during the through vehicles line ball, and the crossing supervising device is taken when left turn lane vehicle line ball.
Step S203, when the signal lamp red light goes out entirely, send second switching signal to the crossing supervising device by radio port;
When turning left and the two track red lights of keeping straight on when all going out, signal lamp can send two second switching signals to the crossing supervising device by radio port.
Step S204, crossing supervising device switch to holding state according to second switching signal.
When the situation of multilane monitoring occurring, second switching signal that the crossing supervising device only gets access to track quantity respective amount just can switch to holding state.In embodiments of the present invention, when the crossing supervising device gets access to two second switching signals, do not take even switch to holding state vehicle line ball this moment crossing supervising device yet.
