According to the invention, control of time of the traffic light can be performed via automatic induction of flow, artificial control of time of the traffic light can be performed under a special situation or in an emergency, reasonable planning on road traffic can be realized, artificial adjustment on emergencies can be performed, and more rationalization and humanization are realized.

Description

A kind of flow sensing traffic lights

Technical field

The invention belongs to the electronic installation technical field, particularly a kind of flow sensing traffic lights.

Background technology

The fast development in city makes the quantity of automobile continue to increase, urban transportation also becomes and blocks up day by day, some situation is the excessive traffic jam that causes of vehicle flowrate, automatically the traffic lights device of inductive flow has been arranged at present, can control the time of traffic lights according to the flow on the road, but first, existing traffic lights induction installation all is automatic, and program all configures, and control center can't adapt to the site traffic situation to program adjustment when the situation of running into need be made adjustment; The second, when traffic accident or emergency occurring, the traffic police can not control traffic lights according to field condition.

Summary of the invention

The present invention is directed to the defective of background technology, proposed a kind of flow sensing traffic lights, both kept automatic inductive flow and carried out the control of traffic lights time, control center can have better adaptability according to the traffic change flow control program at scene simultaneously; Can when special or emergency condition occurring, the traffic police can reasonably plan road traffic at the time of field condition control traffic lights again, run into adjusting that emergency situations can be artificial, rationalize more, hommization.

In order to solve the problems of the technologies described above, the technical solution used in the present invention is:

A kind of flow sensing traffic lights, comprise pushbutton switch, power module, wireless transmitter module, wireless receiving module, flow sensor, single chip machine controlling circuit, LED traffic lights and The Cloud Terrace camera, wherein, power module links to each other with pushbutton switch, power module is powered to single-chip microcomputer when pushbutton switch is closed, and powers to other parts by single-chip microcomputer; Wireless transmitter module links to each other with wireless receiving module, single chip machine controlling circuit respectively with power module, wireless receiving module, flow sensor, the LED traffic lights link to each other with the The Cloud Terrace camera, described single chip machine controlling circuit also communicates with traffic control control center.

As further prioritization scheme of the present invention, also comprise the GSM communication module that links to each other with single chip machine controlling circuit.

The present invention adopts above technical scheme compared with prior art, has following technique effect:

The first, kept the function that existing induction traffic lights can be regulated the time automatically according to traffic, also increased multiple control modes such as Long-distance Control, wireless remote control, GSM control, flow control, control mode is more flexible;

The second, adopt single chip circuit to control, be convenient to follow-up function upgrading;

Three, according to flow efficient real time control traffic lights, at utmost bring into play the handling capacity of highway.

Description of drawings

Fig. 1 is functional-block diagram of the present invention.

Embodiment

Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated:

The invention provides a kind of flow sensing traffic lights, as shown in Figure 1, comprise pushbutton switch, power module, wireless transmitter module, wireless receiving module, flow sensor, single chip machine controlling circuit, the LED traffic lights, traffic control control center and The Cloud Terrace camera, wherein, pushbutton switch links to each other with power module, power module is the single chip machine controlling circuit power supply, and be responsible for the power supply of entire circuit by single chip machine controlling circuit, wireless transmitter module links to each other by communication with wireless receiving module, single chip machine controlling circuit respectively with power module, wireless receiving module, flow sensor, the LED traffic lights, the The Cloud Terrace camera links to each other.Described single chip machine controlling circuit also connects the GSM communication module, utilizes this GSM communication module and traffic control control center to carry out communication.

Provide control mode and the course of work of flow sensing traffic lights below:

The user presses the button switch, and power module is powered to system, enters holding state after the single chip machine controlling circuit initialization.

Under the normal condition, write light on and off order and the perdurability of LED traffic lights routine in the single-chip computer control system in advance.The The Cloud Terrace camera has The Cloud Terrace, the range of observation that changes the The Cloud Terrace camera can rotate by the Long-distance Control The Cloud Terrace in traffic control control center, by the The Cloud Terrace camera, traffic control control center can understand the current magnitude of traffic flow in real time, and there are three kinds of control modes in traffic control control center then:

A, traffic control control center directly import light on and off order and the perdurability that instruction changes the LED traffic lights;

B, traffic control control center control light on and off order and the perdurability of LED traffic lights synchronously, in real time according to real-time flow information input instruction;

C, traffic control control center start the flow sensor control mode.

Flow sensor sends flow information to single chip machine controlling circuit after detecting the flow of two road direction, single chip machine controlling circuit judges that through computing which vehicle flow is big, can increase the turn-on time of the big road green light of flow then, alleviate traffic pressure, big vehicle flow is still very big if flow sensor detects flow, single chip machine controlling circuit can continue to increase the turn-on time of the big road green light of flow, just no longer changes light on and off order and the perdurability of LED traffic lights when the flow of two roads is equally big.

Traffic-police can also use wireless transmitter module emission remote signal at the scene, after wireless receiving module receives remote signal, send control signal to single chip machine controlling circuit, single chip machine controlling circuit is alleviated traffic pressure according to light on and off order and the perdurability of instruction change LED traffic lights.

If make traffic control control center be connected interruption with the operation circuit of traffic lights for some reason, traffic control control center can also send the control note to the GSM communication module by GSM network (global system for mobile communications), changes light on and off order and the perdurability of LED traffic lights according to flow.
