Technical Field
[0001] The utility model belongs to the technical field of weighing, and particularly relates to a weighing device for weighing trucks passing over a weighing scale. Background Art
[0002] The vehicle ground sensing system for weighing trucks passing over a weighing scale is an important means for managing vehicles entering and leaving the weighing scale. It can effectively intercept illegally weighed vehicles or release legally weighed vehicles.
[0003] Currently, the most commonly used method is to issue an IC card to each vehicle entering the weighing scale. When a vehicle enters, the IC card needs to be held near the card reader installed at the vehicle entrance close to the card reading area. After the card reader recognizes the card, the gate will be automatically opened by the card reader controller, and the vehicle can drive onto the weighing scale. When the vehicle finishes weighing and drives out, it needs to hand back the IC card. Since the vehicle needs to stop and swipe the card every time it enters and exits the weighing scale, a long queue for swiping cards will occur, which is not only cumbersome but also not conducive to the efficient operation of the weighing scale.
[0004] There is also the following method in the prior art, that is, when the vehicle arrives at the door, the camera will take pictures and scan the vehicle to collect information and then open the door, and then close the door after the vehicle passes. This solution is not applicable to restricting the order of weighed vehicles on the weighing scale to weigh stably. It has defects. If both the front and rear doors of the weighing scale collect information through camera scanning, it takes too much time and the efficiency is low.
[0005] In view of the above factors, the present utility model provides a weighing device for weighing trucks passing over a weighing scale, which can record and monitor all vehicles entering and leaving the weighing scale, is convenient, fast, safe and reliable, and ensures the safety of the weighing scale for entry and exit.

[0035] An image acquisition device is arranged along the driving mode of the weighbridge 1, and the image acquisition device includes a first acquisition end 5 and a second acquisition end 6;
[0036] The induction device 4 is electrically connected to the main controller, and the first barrier gate 2 and the second barrier gate 3 are electrically connected to the main controller.
[0037] In the use state, the opening of the first barrier gate 2 and the second barrier gate 3 is controlled by the main controller. There is a control cabinet or an independent control room 7 on one side of the weighbridge. The main controller is arranged in the control cabinet or the independent control room 7, and the main controller is a PC.
[0038] In order to facilitate weighing and out-of-weighbridge reminder by setting a vehicle detector coil in the use state, the induction device 4 is a vehicle detector coil, and the vehicle detector coil is in a rectangular shape or an 8-shaped shape.
[0039] When the front wheels of the vehicle being weighed pass through the vehicle detector coil, the main controller controls the first barrier gate 2 to open.
[0040] When the vehicle being weighed finishes weighing, the main controller controls the second barrier gate 3 to open. When the vehicle being weighed drives out of the weighbridge and passes through the vehicle detector coil at the exit position, after the rear wheels of the vehicle drive out of the vehicle detector coil and the main controller no longer receives the change of the vehicle detector coil, the main controller controls the second barrier gate 3 to close.
[0041] In order to facilitate determining the wheel position of the vehicle being weighed by setting an electronic weighing monitor in the use state, the induction device 4 is an electronic weighing monitor. The electronic weighing monitors are symmetrically arranged, and the width of the electronic weighing monitor covers the vehicle wheel body.
