Description
Technical Field
[0001] The utility model relates to a single-lane electronic queuing passing command device, belonging to the technical field of traffic control devices. Background Technique
[0002] Due to considerations such as cost and site limitations, some weighbridges in factories and mines can only use a single weighbridge to weigh empty and loaded transport vehicles at the same time. When the transportation operation is heavy, individual vehicles cutting in line and rushing through easily cause traffic jams. When necessary, manual traffic command is also required, and it is very dangerous for the command personnel to walk through the traffic flow.
[0003] The use of a PLC system has a high investment. During on-site debugging, the frequency converters are mostly started and stopped in a remote control mode. If it is changed to local panel operation, it is impossible to eliminate control circuit faults and faults of the control terminals of the frequency converters themselves, and repeated troubleshooting and testing are required, consuming a large amount of time and manpower.

[0015] A single-lane electronic queuing and passing command device includes a straight-bar gate 1, traffic lights 2, a vehicle detector, a diffuse reflection type infrared proximity switch, an intermediate relay, a disconnection delay relay, and a reset button SB. One end of a single-platform combined truck scale 3 is the direction for empty trucks to get on the scale, and the other end is the direction for loaded trucks to get on the scale. There are two sets each of the straight-bar gate 1, traffic lights 2, vehicle detector, and diffuse reflection type infrared proximity switch, which are respectively installed at both ends of the single-platform combined truck scale 3; the diffuse reflection type infrared proximity switch is connected to the disconnection delay relay through the vehicle detector and the intermediate relay, the output end of the disconnection delay relay is connected to the straight-bar gate 1, and the intermediate relay controls the traffic lights 2; the reset button SB is connected to the intermediate relay.
[0016] The diffuse reflection type infrared proximity switch includes an empty-truck proximity switch SQ1 and a loaded-truck proximity switch SQ2. The empty-truck proximity switch SQ1 is set at one end of the single-platform combined truck scale 3 in the direction for empty trucks to get on the scale, and the loaded-truck proximity switch SQ2 is set at one end of the single-platform combined truck scale 3 in the direction for loaded trucks to get on the scale.
[0017] There are two disconnection delay relays, which are respectively an empty-lane gate lifting signal disconnection delay relay KT1 and a loaded-lane gate lifting signal disconnection delay relay KT2. The empty-lane gate lifting signal disconnection delay relay KT1 and the loaded-lane gate lifting signal disconnection delay relay KT2 are respectively connected to the empty-truck proximity switch SQ1 and the loaded-truck proximity switch SQ2.
[0018] There are two sets of the traffic lights 2, which are respectively a red light 21 in the loaded-truck direction and a green light 23 in the empty-truck direction, and a red light 22 in the empty-truck direction and a green light 24 in the loaded-truck direction. The red light 21 in the loaded-truck direction and the green light 23 in the empty-truck direction are set at one end of the single-platform combined truck scale 3 in the direction for empty trucks to get on the scale, and the red light 22 in the empty-truck direction and the green light 24 in the loaded-truck direction are set at one end of the single-platform combined truck scale 3 in the direction for loaded trucks to get on the scale.
[0019] There are three intermediate relays, which are respectively a weighing indication relay KA1, an empty-truck indication relay KA2, and a loaded-truck indication relay KA3. The reset button SB is respectively connected to the weighing indication relay KA1, the empty-truck indication relay KA2, and the loaded-truck indication relay KA3; the empty-truck indication relay KA2 is connected to the red light 21 in the loaded-truck direction and the green light 23 in the empty-truck direction, and the loaded-truck indication relay KA3 is connected to the red light 22 in the empty-truck direction and the green light 24 in the loaded-truck direction.
[0020] In practical applications, the working process is as follows:
[0021] 1. One end of the single-platform combined truck scale 3 is the direction for empty trucks to get on the scale, and the other end is the direction for loaded trucks to get on the scale.
[0022] 2. The straight-bar gate 1, traffic lights 2, and diffuse reflection type infrared proximity switches are installed at both ends of the single-scale multiplexed truck scale 3. When there is no vehicle at both ends of the single-scale multiplexed truck scale 3, the straight-bar gate 1 is default in the lowered state, and the traffic lights are in the green light state. At this time, the weighing indication relay KA1, the empty vehicle indication relay KA2, and the heavy vehicle indication relay KA3 are all in the non-energized state. The empty lane gate lift signal disconnect delay relay KT1 and the heavy lane gate lift signal disconnect delay relay KT2 are in the reset state;
[0023] 3. When the diffuse reflection type infrared proximity switch at the empty vehicle on-board direction end of the single-scale multiplexed truck scale 3 detects an approaching vehicle, the empty vehicle proximity switch SQ1 operates, the empty vehicle indication relay KA2 energizes and triggers the operation of the empty lane gate lift signal disconnect delay relay KT1. The straight-bar gate at the empty vehicle on-board direction end lifts up, the green light 23 at the empty vehicle direction lights up, and the red light 21 at the heavy vehicle direction goes out. The green light 24 at the heavy vehicle direction at the heavy vehicle on-board direction end goes out, and the red light 22 at the empty vehicle direction lights up. The vehicle drives onto the scale. When it passes the vehicle detector, the straight-bar gate drops;
[0024] 4. When the diffuse reflection type infrared proximity switch at the heavy vehicle on-board direction end of the truck scale detects an approaching vehicle, the heavy vehicle proximity switch SQ2 operates, the heavy vehicle indication relay KA3 energizes and triggers the operation of the heavy lane gate lift signal disconnect delay relay KT2. The straight-bar gate at the heavy vehicle on-board direction end lifts up, the green light 24 at the heavy vehicle direction lights up, and the red light 21 at the heavy vehicle direction at the empty vehicle on-board direction end lights up. The vehicle drives onto the scale. When it passes the vehicle detector, the straight-bar gate drops;
[0025] 5. After the vehicle weighing on the truck scale is completed, the weighbridge operator presses the reset button SB;
[0026] 6. After the reset button SB is pressed, the weighing indication relay KA1 energizes. If there is no vehicle at both ends of the single-scale multiplexed truck scale, the empty vehicle indication relay KA2 resets and the heavy vehicle indication relay KA3 resets, then the green lights 23 at the empty vehicle direction and 24 at the heavy vehicle direction both light up;
[0027] 7. When the reset button SB is pressed, if the diffuse reflection type infrared proximity switch at the empty vehicle on-board direction end of the single-scale multiplexed truck scale detects an approaching vehicle, repeat step 3. If the diffuse reflection type infrared proximity switch at the heavy vehicle on-board direction end of the truck scale detects an approaching vehicle, repeat step 4;
[0028] The passing rule for both ends of the single-scale multiplexed truck scale is preemptive, and the vehicle in the direction of the first arrival passes first. If vehicles continuously arrive on one side, they queue up to pass. This utility model only has several relays and a small amount of wiring, is applicable to the single-scale multiplexed weighbridge house, and can realize the alternate weighing of vehicles at both ends of the weighbridge or the sequential weighing of vehicles at one end of the weighbridge without on-site personnel command.
