Description

Technical Field

[0001] The utility model relates to the technical field of truck weighing equipment, in particular to an anti-cheating weighing scale. Background Art

[0002] A floor scale, also known as an electronic truck scale, is a device used for weighing bulk cargo. During the transportation of bulk materials like ore and coal, floor scales accurately and quickly measure vehicle loads, ensuring the accuracy and fairness of measurement data. Constructed primarily of reinforced concrete, these scales are equipped with load cells, display instruments, computers, and printers. Their durability and high load-bearing capacity make them widely used in mines, ports, and other locations.

[0003] For example, the Chinese authorized patent with announcement number CN217637615U, "A floor scale device for weighing and measuring heavy trucks", includes a supporting platform and a weighing sensor. The bottom of the supporting platform is provided with a base, a cavity is provided in the base, and a buffer mechanism is provided in the cavity. The buffer mechanism is evenly arranged along the length direction of the base. The buffer mechanism includes a support column, a sliding rod, and a sliding seat. The bottom of the support column is provided with a connecting disk, one end of the sliding rod is hinged to the connecting disk, and the other end of the sliding rod is hinged to the sliding seat, and a sliding groove is provided in the base.

[0004] The above-mentioned existing weighing scale system cannot accurately determine whether the vehicle is fully weighed, and its anti-cheating ability is low. Common cheating methods include: 1. After the front vehicle is fully weighed, the front wheels of the rear vehicle are also weighed at the same time, making the weight of the goods weighed much larger than the actual weight; 2. The driver weighs at a certain speed, and after being fully weighed, the driver suddenly slams on the brakes. At this time, due to inertia, the vehicle will generate a strong impact force on the weighing scale, which also causes the weight of the goods to be much larger than the actual weight. This inaccurate weighing behavior that is larger than the actual weight can easily cause drivers to transport less goods or steal goods, causing huge economic losses to the company. Therefore, it does not meet existing needs. In response to this, we have proposed an anti-cheating weighing scale. Summary of the Invention

[0005] The purpose of the utility model is to provide an anti-cheating weighing scale to solve the problem raised in the above background technology that truck drivers change the actual weight of the truck on the weighing scale due to personal intentions, causing economic losses to the company.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] See also Figure 1-2 The utility model provides an embodiment of an anti-cheating floor scale, comprising a floor scale body 1, a weighing platform 2 being provided at the middle position of the upper end surface of the floor scale body 1; and further comprising:

[0024] The gantry 3 is arranged above the scale body 1, and the longitudinal frames on both sides of the gantry 3 are fixed to the scale body 1 by bolts. The bottom of the horizontal frame on the gantry 3 is installed with an array radar 4, and the array radar 4 is located directly above the weighing platform 2;

[0025] The central controller cabinet 9 is located on one side of the scale body 1 and has a built-in control chip. A display screen 10 is installed above the central controller cabinet 9, and the input end of the display screen 10 is electrically connected to the output end of the control chip. The control chip receives input signals from equipment such as the scale, array radar, infrared radiation device, and camera. It uses a built-in algorithm to analyze vehicle status, location information, weight data, etc. to determine whether there is cheating behavior. If an abnormality is found, the voice prompt device is immediately triggered to issue a warning and record relevant evidence for subsequent processing. At the same time, the central controller is also responsible for uploading data such as weighing results and surveillance videos to a server or remote monitoring center to achieve remote monitoring and management.

[0026] When in use, the array radar 4 transmits electromagnetic waves and receives reflected signals to calculate the distance and angle between the truck and the radar, forming a three-dimensional image of the vehicle. Each truck needs to be measured twice: the volume and weight are measured when empty and fully loaded. The empty measurements are recorded as m1 and v1, and the fully loaded measurements are recorded as m2 and v2. The weight of the cargo is obtained as (m2-m1) and the volume of the cargo is obtained as (v2-v1). If (m2-m1) / (v2-v1) is a normal value, it means that the cargo data loaded on the truck is the real value and there is no cheating. If (m2-m1) / (v2-v1) is less than or greater than the normal value, it means that the cargo data loaded on the truck contains false components and there is cheating. At this time, an alarm is issued through the control chip to notify the staff to handle it. Since the anti-cheating software built into the control chip is a prior art, it will not be described in detail.

[0027] See also Figure 1 and Figure 2 , infrared radiation devices 5 are provided on both sides of the entrance and exit of the weighing scale body 1, and the output end of the infrared radiation device 5 is electrically connected to the input end of the control chip, providing accurate position detection when the vehicle enters and leaves the weighing scale area, and assisting in judging whether the vehicle is fully weighed. It consists of a transmitter and a receiver, which are installed on both sides of the gantry 3 to form one or more invisible infrared barriers. When the vehicle passes completely, it will block or interrupt the infrared beam, the receiver detects the signal change, and transmits this information to the central controller. By using a combination of multiple sets of infrared radiation devices, the position of the vehicle can be accurately determined, and cheating behaviors such as incomplete weighing of trucks and increased counterweights on vehicles can be avoided, thereby ensuring the authenticity of transaction data.

[0028] See also Figure 1 and Figure 2 A warning light 6 and a voice prompt device 7 are respectively provided on one side of the gantry 3. The voice prompt device 7 is located below the warning light 6, and the input ends of the warning light 6 and the voice prompt device 7 are electrically connected to the output end of the control chip. According to the instructions of the central controller, operation guidance and violation warnings are provided to the driver. After receiving the signal from the central controller, the preset voice message is played, such as "Please drive slowly and weigh completely", "The vehicle position is incorrect, please readjust", etc., to enhance the human-computer interaction experience and improve the operation standardization.

[0029] See also Figure 1 and Figure 2 A camera 8 is also installed on one side of the entrance to the scale body 1. The image output terminal of the camera 8 is electrically connected to the input terminal of the control chip. The camera records the entire process of the vehicle weighing, which serves as a basis for subsequent verification and prevents cheating. The high-definition camera monitors and records the vehicle and the scale area in real time. The video data is transmitted wirelessly to the central controller or remote monitoring center for management personnel to view at any time.
