The sensors in this embodiment can be in wired communication or wireless communication with the control host, and if the sensors are in wireless communication, a wireless communication module (including signal transmitting, signal receiving and signal basic processing function modules are integrated), which can be purchased in the market, and belongs to a mature application product

The utility model sets a limit cross bar on the fork road and a prompt warning lamp on the main road side: when a vehicle runs from a fork road to a main road, the sensor A is triggered in advance, and a warning lamp on the side of the main road immediately flashes; three seconds (or other set time) later, the row-restricting cross bar is opened; after the vehicle leaves the sensor B, the limit cross rod is automatically closed, and the warning light on the main road stops flashing after a delay of a few seconds. In the process, the vehicles on the main road can see the flashing of the prompt warning lamp, and the vehicles entering the cross road can be known, so that the speed can be controlled and the situation of the crossing can be attended to. After a vehicle on a road is parked (or slowly moved) for a certain time, not only is a reminding alarm obtained, but also the traffic speed is controlled well, so that potential safety hazards can be reduced greatly; when a vehicle enters the fork road from the main road, the sensor B is triggered by the traveling of the vehicle, the travel limiting cross rod is automatically opened, and after the vehicle leaves the sensor A, the travel limiting cross rod is automatically closed.

The middle limit horizontal rod is provided with a manual opening and closing horizontal rod: in order to prevent major accidents caused by mistaken collision of the cross bars, the cross bars are designed into a limited-movement cross bar which is automatically opened and closed by electric power and a manual opening and closing cross bar, and the electric opening and closing part is controlled by the sensors A and B, so that the working mode is as described above. The manual opening and closing of the cross rod part adopts a spring slight locking mechanism, so that wind power cannot act, but manpower can act easily; even if the vehicle is collided by mistake, the large damage can not be caused. The automatic control device can also pass through the manual opening and closing device after the automatic control function fails, specifically, under the normal state, the torsion spring pulls the manual opening and closing cross rod to lean against the limiting backup plate so as to keep the transverse state, and when a person bends the manual opening and closing cross rod by 90 degrees, the manual opening and closing cross rod is fixed by 90 degrees through the plug pin jack.

In the utility model, the sensor C is arranged at the joint of the automatic opening and closing part and the manual opening and closing part of the limited-movement cross rod, when the limited-movement cross rod and the manual opening and closing part are opened by external force, if the limited-movement cross rod and the manual opening and closing part still do not return to a normal station after a certain time, the sensor C can send an abnormal signal to a control center system through a control host, each set of devices is documented in the system in advance, and after receiving the abnormal signal, the system can immediately give an alarm and accurately report the abnormal position. At this time, the personnel can be arranged by a traffic management, a transport management or other operation service mechanisms to go to the abnormal position for checking and repairing. The control host machine is internally provided with a warning horn, and when the control host machine sends an abnormal signal to the control center, the warning horn simultaneously sends warning words such as 'system fault, careful passing', and the like, and after the abnormality is repaired, the warning horn is automatically released.

The whole system of the utility model can be powered by solar energy or wind energy.

The device is mainly suitable for the cross road which is not suitable for mounting traffic lights and has a narrow road surface (the recommended width is within 6 meters), particularly for village areas, and places where some road surfaces are only 1-2 meters wide, but motorcycles and electric vehicles can often appear. For the fork road with the width smaller than 3 meters, a unilateral device is arranged.

As shown in fig. 1. The sensor A and the sensor B are arranged at the roadside at the two ends of the passing-in fork road to control the passing-out fork road to drive in and out

The sensors of the main road are sensors A and the sensors capable of releasing the main road vehicles to drive to the fork road are sensors B, and each sensor is two in one group. When no vehicle exists, the two groups of sensors respectively send and receive signals, and the whole device is in a closed state. When a car passes, the signal transmission and the signal reception between the sensors are blocked, and the host can recognize that the car passes and start working. When the vehicle is driven from the fork road to the main road, the system: (1) the reminding warning lamp is turned on, and the warning lamp flashes to warn to remind the vehicles on the main road to pass carefully; (2) starting a time delay opening function, opening the row limiting cross bar after 3 seconds (or other preset time), and slowly passing the vehicle after slightly waiting; (3) after the vehicle is driven away, the travel limiting cross rod is automatically closed, and the system is reset. Thus, the speed of the vehicle entering the main road is relatively low, and the safety is greatly improved.

Fig. 2 is a schematic diagram of the automatic opening of the horizontal bar, and the normal passing of the vehicle is not affected at all.

Fig. 3 is a schematic view of the manually opened and closed crossbar portion. When the system fails, the manual opening and closing part on the limit cross bar can be opened manually, and the vehicle can still normally pass as shown in the figure.

When a vehicle does not notice the front cross rod and other prompt marks or does not wait for the preset automatic opening time, the manual opening and closing cross rod can be crashed when the vehicle passes through forcefully, and the manual opening and closing part of the manual opening and closing cross rod is made of light aluminum alloy, so that the vehicle is not damaged greatly even if the vehicle collides with the manual opening and closing part. The manual opening and closing part and the automatic opening and closing part are connected through a spring slight locking mechanism, the degree of tightness is that the opening can not be realized under natural external force such as wind force, and the manual opening and closing part can be easily opened when being manually operated or impacted, so that the error impact loss is reduced as much as possible.

In order to prevent the traffic accident caused by false running of the front limit cross bar when the running vehicle is not clear, a sub sensor a is arranged at a distance of 50-100 meters in front of the limit cross bar, and once the sub sensor senses that the running vehicle passes by, a voice broadcasting device arranged on the sub sensor a simultaneously broadcasts a voice prompt: the passing vehicles notice that the front is provided with the intersection, the speed of the passing vehicles is reduced, the content of voice broadcasting is designed in advance, and the triggering signals are played, so that the vehicles can be well reminded of reducing the speed, the impact bar accidents are avoided, and in the embodiment, the sensors and the voice broadcasting devices provide sufficient time for the speed reduction of the vehicles, so that the impact bar accidents basically cannot occur.

It is also necessary to provide a limit rail in this embodiment, i.e. to limit the speed reduction of passing vehicles for human intervention.

The manual opening and closing cross rod and the limit cross rod can be opened and closed by +/-90 degrees according to a preset program, and the automatic function is opened along the forward direction every time so as to facilitate the passing of vehicles.

The whole system is controlled by a microcomputer, and a self-developed special chip is used to ensure safety and reliability.

The signal transmission among the control host, the sensor and the warning lamp is wireless transmission and wired transmission, and can be specifically determined according to the road surface condition. The signal transmission of the sensor C and the control center system is carried out by a mobile telephone network, so that the system is efficient, practical and low in cost.
