Problems solved by technology

[0002] The road condition at the intersection where the curve connects is complex, such as a coal mine transportation line. A intersection involves multiple lines crossing and there are curves. The traditional red and green light display system has a narrow visual range, and it is easy for drivers to fail to find the signal in time.
In view of this situation, at present, the main measures are to limit the driving speed and install curve alarms to solve safety problems. Some places rely on telephones and on-site cadres to direct transportation and production work. However, the above measures also have a large range of blind spots and cannot fully guarantee the passage of vehicles. Safety
[0003] In addition, the light signal of the traditional signal light is instructed according to the set program. It is easy to wait for the red light when there is no vehicle at the intersection, which affects the traffic efficiency.

Embodiment 1

[0040] Driving route at a fork such as figure 1Shown: There are two entrances in the picture: A and B, because M is equal to the number of entrances, so M is 2; there is one exit in the picture: C, N is equal to the number of exits, so N is 1; there are two routes in the picture : A to C, B to C. Set up LED traffic lights for drivers to observe in front of the entrances of the two curved roads, and set trigger equipment at the entrance of the fork. The trigger equipment in this embodiment is a wire pantograph scraping signal terminal. The corresponding trigger relay in the controller is energized; the wire collecting pantograph scraping signal terminals are respectively set at the exit. The operating voltage of the cable pantograph scraping signal terminal is DC100V, and the operating voltage of the LED traffic lights is AC220V.

[0041] combine Figure 1 to Figure 6 As shown, each route is explained in detail:

[0042] Vehicles traveling from A to C, before entering the i...

Embodiment 2

[0045] The driving route of a fork in a coal mine is as follows: Figure 7 Shown: There are 3 entrances in the picture: E1, E4, E5, so M is 3; there are 3 exits in the picture: E2, E3, E5, so N is 3; there are four routes in the picture: E1 to E3, E4 to E2, E4 to E5, E5 to E3. In particular, E5 is not only the entrance from E5 to E3, but also the exit from E4 to E5, so E5 is provided with two trigger devices, one is connected to the coil part of the trigger relay, and the other is connected to the coil part of the release relay. Like Embodiment 1, LED traffic lights for drivers to observe are arranged in front of the entrances of the two curved roads, and a trigger device is set at the entrance of the fork. The trigger device in this embodiment is a wire pantograph scraping signal terminal. After the vehicle passes through the terminal, the corresponding trigger relay in the main controller is energized; the cable pantograph scraping signal terminal is respectively set at the...

Abstract

The invention relates to an automatic signal system and provides an automatic signal system at a fork. The automatic signal system at the fork aims to improve vehicle traffic efficiency and guarantee driving safety of vehicles at the curve fork. The automatic signal system at the fork comprises entrance triggering devices, exit triggering devices, traffic light equipment and a master control box, wherein the entrance triggering devices are arranged in front of entrances of the fork, the exit triggering devices are arranged at exits of the fork, and the traffic light equipment is arranged in front of the fork. The master control box comprises M triggering relays, N removal relays and M control relays, wherein M refers to the number of the entrances, and N refers to the number of the exits. Coil parts of the triggering relays are connected with the entrance triggering devices arranged at the entrances of the fork, coil parts of the removal relays are connected with the exit triggering devices arranged at the exits of the fork, and contact parts of the control relays are connected with the traffic light equipment. The automatic signal system at the fork is suitable for curve forks.

Description

technical field [0001] The invention relates to an automatic signal system, in particular to a fork automatic signal system. Background technique [0002] The road condition at the intersection where the curve connects is complex, such as a coal mine transportation line, where multiple lines intersect and there are curves at an intersection, the traditional red and green light display system has a narrow visual range, and it is easy for drivers to fail to find the signal in time. In view of this situation, at present, the main measures are to limit the driving speed and install curve alarms to solve safety problems. Some places rely on telephones and cadres to direct the transportation and production work on the spot. However, the above measures also have a large range of blind spots and cannot completely guarantee the passage of vehicles. Safety. [0003] In addition, the light signal of the traditional signal light is instructed according to the set program. It is easy to...
