[0038] like Figure 1As shown, the high-precision dynamic and static weighing method provided in the first aspect of this embodiment can be executed by, but is not limited to, a computer device with certain computing resources, such as a personal computer (PC, referring to a multi-purpose computer with a size, price and performance suitable for personal use; desktops, laptops, small laptops, tablets and ultrabooks are all personal computers), smart phones, personal digital assistants (PAD), wearable devices or platform servers and other electronic devices, so as to obtain static data and dynamic data of the vehicle through the image acquisition device, wherein the static data includes license plate data and vehicle type, and the dynamic data includes the driving path and driving speed of the vehicle within a preset range; retrieve the preset driving path and preset driving speed matching the vehicle type; when the driving path is within the preset driving path and the driving speed is at the preset driving speed, control the limiter arranged on the outer periphery and bottom of the load-bearing scale body to retract; obtain the weighing data collected by the weighing sensor, bind the weighing data with the license plate data, and send the vehicle weighing result to the display terminal; control the road gate to open to facilitate the passage of the vehicle. Based on the remote automatic weighing, combined with the vehicle type and vehicle status, the vehicle weighing is guided, thus improving the weighing accuracy of the scale. Figure 1 As shown, the high-precision dynamic and static weighing method may include but is not limited to the following steps S11 to S15. It is clear that the limiter is an electric support structure for resisting the load-bearing scale body, and after the load-bearing scale body reaches the weighing condition, the resisting force is adjusted to enable the load-bearing scale body to weigh.

[0039] Step S11, acquiring static data and dynamic data of the vehicle through an image acquisition device, wherein the static data includes license plate data and vehicle type, and the dynamic data includes the driving path and driving speed of the vehicle within a preset range;

[0040] In step S11, the image acquisition device may be a camera or other imaging device, which may be arranged in front, behind, left and / or right of the weighbridge, so as to monitor the position of the vehicle relative to the weighbridge; for example, the camera is arranged in front of the vehicle entering the weighbridge, and the relative position of the vehicle entering the weighbridge and the time corresponding to the position are photographed in real time, and the driving path and driving speed of the vehicle within a preset range are calculated. The preset area may be a specific area preset around the weighbridge, that is, the area with a high probability of the vehicle entering the weighbridge. At the same time, the type of vehicle corresponding to the vehicle, that is, the conventional configuration of the vehicle, is identified through the recorded image; and the license plate data of the vehicle may be identified through image recognition technology.

[0041] Step S12, retrieving a preset driving path and a preset driving speed that match the vehicle type;

[0042] According to the acquired vehicle type, the preset driving path and preset driving speed matching the vehicle type are obtained from the pre-stored list, so as to guide the vehicle to enter the scale for weighing according to the preset driving path and driving speed; it is clear that when the vehicle type is obtained, the wheelbase and center of gravity of the vehicle can be judged, so the vehicle can be more accurately guided into the most suitable weighing area for weighing.

[0043] Step S13, when the driving path is within the preset driving path and the driving speed is at the preset driving speed, controlling the limit members arranged on the outer periphery and the bottom of the load-bearing scale body to retract;

[0044] In order to prevent vehicles from violently entering the weighing scale, limiters are set to support the weighing scale to prevent vehicles from squeezing the weighing scale; when the driving path is within the preset driving path and the driving speed is at the preset driving speed, the vehicle weighing is in the best state, that is, the limiters set on the periphery and bottom of the load-bearing scale body are controlled to shrink, so that the gravity sensor can collect weighing data.

[0045] Step S14, obtaining the weighing data collected by the weighing sensor, binding the weighing data with the license plate data, and sending the vehicle weighing result to the display terminal;

[0046] The weighing data collected by the weighing sensor needs to be bound to the vehicle's license plate data, and the weighing result is sent to the display end for display; it is clear that the display end can include multiple displays; for example, a floor scale display and a service center display for verification by the weighing vehicle driver and administrator.

[0047] Step S15, obtaining the weighing data collected by the weighing sensor, binding the weighing data with the license plate data, and sending the vehicle weighing result to the display terminal.

[0048] After the weighing data is collected, the license plate data is bound to the weighing data and sent to the display end, which can be the display end at the scale and the display end of the service end, for the vehicle driver to confirm or the service end personnel to review, and the vehicle's weighing data is recorded at the same time.

[0049] Therefore, based on the high-precision dynamic and static weighing method described in the aforementioned steps S11 to S15, a solution is provided for guiding vehicle weighing based on remote automatic weighing and combining the vehicle type and vehicle status to improve the accuracy of weighing on the scale, namely, obtaining the static data and dynamic data of the vehicle through an image acquisition device; retrieving the preset driving path and preset driving speed that match the vehicle type; when the driving path is within the preset driving path and the driving speed is at the preset driving speed, controlling the limiter set on the outer periphery and bottom of the load-bearing scale to retract; obtaining the weighing data collected by the weighing sensor, binding the weighing data with the license plate data, and sending the vehicle weighing result to the display terminal; and controlling the gate to open. Based on remote automatic weighing, combining the vehicle type and vehicle status to guide vehicle weighing improves the accuracy of weighing on the scale; thereby solving the problems of low operating efficiency and high error rate of traditional scales, and the need for manual review of whether the vehicle is cheating in remote automatic weighing, which wastes human resources and cannot guarantee the accuracy of weighing on the scale.

[0052] In this embodiment, when the driving path is not within the preset driving path and / or the driving speed is not within the preset driving speed, the limiting members arranged on the outer periphery and the bottom of the load-bearing scale are controlled to hold the load-bearing scale body to prevent the vehicle from damaging the scale; when it is detected that the vehicle is within the preset driving path and the driving speed is at the preset driving speed, the limiting members arranged on the outer periphery and the bottom of the load-bearing scale body are controlled to retract to weigh the vehicle.
