Abstract

The utility model discloses a single-lane two-way traffic signal lamp control device. It is mainly composed of two parts: vehicle detection device and main control device. A single-lane two-way traffic signal control device includes 4 sets of vehicle detection devices and 2 main control devices. Each group of vehicle detection devices includes a photoelectric transmitting platform 3 and a photoelectric receiving platform 2. Two groups of vehicle detection devices are placed on both sides of the entrance road at an interval of 2.5m, and two groups of vehicle detection devices and a group of master control are placed at each intersection device. The vehicle detection device detects that there is a vehicle passing through, and then transmits the signal to the wireless receiving module of the main control device at the A and B entrances through the wireless transmission module 8, and the wireless receiving module transmits the signal to the single-chip microcomputer. After the single-chip processing, the traffic is controlled by the driving circuit. The light of the signal lamp 6 is turned on and off, so as to achieve the purpose of controlling the orderly passage of single-lane vehicles. The device is simple in structure and low in cost, and is of great significance for solving the traffic problem of single-lane vehicles.

Description

Bicycle road opposing traffic traffic signals lamp control device

Technical field

The utility model belongs to traffic administration and control field, is specifically related to a kind of bicycle road opposing traffic traffic signals lamp control device.

Background technology

The bicycle road that the construction initial stage designs because vehicle flowrate is less is arranged in the reality, also have the bicycle roads that much caused by reasons such as constructing tunnel, traffic hazard, geologic hazards, the demand of opposing traffic is often being born in this track.Vehicle vehicle often occurs and fails the current order of rational allocation on this track in the driving process, meets in opposite directions and gets lodged in problem on the bicycle road, and this problem not only has a strong impact on the efficient of road circulation, also might further cause traffic hazard.

At bicycle road opposing traffic traffic jam issue, existing solution is manually to command and cooperate various emergent traffic aids, for example warning sign, roadblock etc.At the mountain road turning that geologic hazard easily takes place, then many employings arrange the methods of convex lens.All there are some drawbacks in these two kinds of methods, as convex lens are set can be subjected to weather and environmental limit, and artificial commander then can expend a large amount of manpower and materials, and commanding's safety is threatened.The present utility model a kind of bicycle road opposing traffic traffic signals lamp control device, it is arranged on 2 ports of one-way road, can be automatically change the traffic lights color according to the wagon flow situation, staff vehicles is current.

The utility model content

Bicycle of the present utility model road opposing traffic traffic signals lamp control device is mainly used in one-lane current commander.The utility model mainly is made of motor vehicle detector, master control set two large divisions, and a cover bicycle road opposing traffic traffic signals lamp control device comprises 4 groups of motor vehicle detectors and 2 master control sets.

One group of motor vehicle detector comprises the photoemission stand and photoelectricity receives each one of stand, the photoemission stand is that photoemission cell is installed on the mobile stand, photoelectricity receives stand except photoelectric receiving tube being installed on the mobile stand, and wireless module also is installed.During use photoemission stand and photoelectricity are received the both sides that stand is placed on road, when no vehicle passes through, the optoelectronic switch normally off, when having vehicle to pass through, optoelectronic switch disconnects.Wireless module can arrive master control set with the state transfer of optoelectronic switch.For fear of the interference of pedestrian or bicycle, two groups of motor vehicle detectors need be set a monitoring point detect the current of vehicle, and one section bicycle road need arrange a monitoring point respectively at two ports.The length of general automobile is more than 3m, and about bicycle 1.8m, therefore two groups of motor vehicle detectors are comparatively reasonable at a distance of the 2.5m placement.

Master control set mainly is configured to by wireless receipts module, single-chip microcomputer, driving circuit, traffic lights, transfer table.Wireless receipts module receives the vehicle pass-through information that receives wireless module transmission on the stand from photoelectricity, and information is transferred to single-chip microcomputer, after single-chip microcomputer is handled signal, the output control signal, through driving circuit, the light on and off of control traffic lights, staff vehicles current.

The utility model control thought is that the bicycle road can not allow two cars pass through in opposite directions simultaneously, and solution is: under normal circumstances two ports in bicycle road (A, B mouth) traffic signal light condition is green light.When A end had vehicle to enter earlier, A end traffic signal light condition kept green light constant, and B end traffic lights become red light, and by the B end, and the A end is when no longer including vehicle and continuing to enter up to vehicle, and B end traffic lights become green light by red light.When A, B two ends have been detected vehicle when entering simultaneously, this moment A, B end traffic lights at random an end become red light.When detecting two ends and have vehicle current continuously, system arranges the current cycle an of the best, and two crossings are alternately current, and this cycle generally is no more than 120s.

The utility model traffic lights adopt common road controlled traffic signal lamp, consider that the scene of traffic hazard has Unpredictability, and power supply of the present utility model can adopt accumulator or two kinds of powering modes of AC power according to demand.

Description of drawings

Fig. 2 is bicycle road opposing traffic traffic signals lamp control device control principle figure.

Fig. 3 is bicycle road opposing traffic traffic signals lamp control device application example.

Among the figure: 1 master control set moves stand; 2 motor vehicle detector photoelectricity receive stand; 3 motor vehicle detector photoemission stands; 4 switches; 5 controllers; 6 traffic lights; 7 photoelectric receiving tubes; 8 wireless modules; 9 photoemission cells; 10 fault highway sections; The 11A entrance; 12B entrance light motor vehicle detector; The 13B entrance; 14 bicycle roads; 15A entrance motor vehicle detector.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As a kind of embodiment of the present utility model, see also Fig. 3.Because the bicycle road 14 that fault forms for the vehicle that A entrance 11 and B entrance 13 are entered can smooth and easyly pass through, needs 4 groups of motor vehicle detectors and two master control sets to form a cover bicycle road opposing traffic traffic signals lamp control device and controls vehicle pass-through.Every group of motor vehicle detector comprises photoemission stand 3 and photoelectricity and receives stand 2 each, and two groups of motor vehicle detectors are placed in each road both sides, monitoring point 2.5m at interval, and 12,15 is respectively the motor vehicle detector group that is placed on A, B portal monitoring point.Master control set stand 1 is respectively put one at A entrance 11 and B entrance 13 places.Master control set has the sniffer of reception signal, the function of control signal lamp 6.

A, B porch traffic lights all are green light under the original state, pass through the A entrance as vehicle, and the B entrance does not have vehicle when passing through, motor vehicle detector group 15 has detected vehicle and has passed through, then by wireless module 8 signal is transferred to simultaneously the wireless receipts module of A, B entrance master control set, wireless receipts module is transferred to single-chip microcomputer with signal again, and single-chip microcomputer is handled and made the traffic lights of A porch become green light by driving circuit, and the traffic lights of B porch become red light.
