Abstract
Description
Technical Field
[0001] The present application relates to the field of building construction, and in particular to a floor scale. Background Art
[0002] At construction sites, weighing scales are often set up. When a transport vehicle enters the construction site, it must first drive onto the weighing scale to be weighed before unloading, so as to quickly obtain the weight of the transport vehicle.
[0003] When using the floor scale, the staff needs to first determine the model of the transport vehicle, and then weigh the transport vehicle to determine whether the transport vehicle is overweight. The staff needs to check closely to determine the model of the transport vehicle, which wastes manpower. The work process has multiple steps and is cumbersome. In addition, the staff needs to be close to the transport vehicle, which has high labor costs. Utility Model Content
[0004] In order to improve the problem of wasting manpower in judging whether a transport vehicle is overweight, the present application provides a floor scale.
[0005] The present application provides a weighbridge, which adopts the following technical solution:
[0006] A floor scale comprises a load-bearing platform for weighing a transport vehicle to obtain weight data, wherein a distance measuring module is arranged on the load-bearing platform, and the distance measuring module is used to measure the wheelbase of the transport vehicle to obtain vehicle model data, a weight threshold is determined by the vehicle model data and a preset model threshold, and whether the transport vehicle is overweight is determined by the weight data and the weight threshold.
[0007] By adopting the above technical solution, the model of the transport vehicle is automatically determined by the axle spacing, and then the weight data is compared with the weight threshold corresponding to the vehicle model to determine whether the transport vehicle is overweight. This reduces the probability of the transport vehicle working in the dust all year round, resulting in the maximum load on the vehicle being obscured by dust and difficult to see, making it difficult for staff to judge whether it is overweight. At the same time, the vehicle model can be identified more accurately, reducing the probability of errors in image recognition when there is soil or other impurities adhering to the vehicle shell. There is no need for staff to stay by the scale all year round, which reduces labor costs, improves convenience, and is more efficient.
[0008] Optionally, the ranging module includes a plurality of ranging plates arranged on the supporting platform and a plurality of pressure sensors for detecting the pressure exerted on the ranging plates, and the plurality of pressure sensors are arranged at different positions of the ranging plates to detect the position of the wheel pressing on the ranging plates.
[0009] By adopting the above technical solution, the contact position between the wheel and the distance measuring plate can be calculated through a plurality of pressure sensors at different positions, which is the position of the axle, which is convenient and quick.
[0010] Optionally, a plurality of the distance measuring plates are distributed along the direction in which the transport vehicle drives onto the load-bearing platform, and the length of the distance measuring plates along the distribution direction is smaller than the minimum wheelbase of the transport vehicle model adapted to the load-bearing platform.
[0011] By adopting the above technical solution, the probability of two axle wheels pressing on one distance measuring plate, which makes calculation difficult, is reduced, and the calculation accuracy is improved.
[0012] Optionally, the ranging module includes a processor for performing data processing and a database for storing data for the processor to call, the database being used to store the weight threshold and position data of the pressure sensor, the pressure sensor obtaining a pressure signal, the processor receiving the pressure signal and weight data, and reading the weight threshold and position data from the database to determine whether the transport vehicle is overweight and obtain a result signal.
[0013] By adopting the above technical solution, data can be stored and called through the database, and data can be calculated and processed through the processor, which is convenient and fast.
[0014] Optionally, an alarm module is included to receive the result signal and output a corresponding alarm signal to the staff through the result signal.
[0015] By adopting the above technical solution, when the load is overloaded, the workers and drivers are reminded by an alarm signal, which is more obvious and reduces the risk of drivers leaving the construction site due to negligence.
[0016] Optionally, an intercepting plate and a control component for controlling the lifting of the intercepting plate are arranged on the carrying platform, the intercepting plate is used to block the front wheels of the transport vehicle, and the control component is used to receive the result signal to control the intercepting plate accordingly.
[0017] By adopting the above technical solution, the position of the front wheel of the transport vehicle is limited by the intercepting plate, so that the position of the wheel of the transport vehicle can fall on the corresponding distance measuring plate, thereby improving efficiency.
[0018] Optionally, the bearing platform includes a bearing platform and a bearing sensor, the distance measuring module and the interception plate are both arranged on the upper end surface of the bearing platform, and the bearing sensor is used to detect the pressure exerted on the bearing platform to obtain the weight data.
[0019] By adopting the above technical solution, the entire load-bearing platform is detected by the load-bearing sensor to obtain weight data, thereby reducing the probability of deviation in the result of adding multiple pressure signals due to uneven force on the ranging plate, thereby improving accuracy.

A rising sensor is provided on the inclined block, and the rising sensor is used to detect the pressure on the upper end surface of the inclined block, and obtain a rising signal to output to the processor to control the lifting and lowering of the intercepting plate.
[0021] By adopting the above technical solution, the inclined block senses the transport vehicle entering or leaving the load-bearing platform, thereby controlling the lifting of the interception plate, which is more automated, convenient and fast, and improves efficiency.
[0022] Optionally, a transmission module is included to receive the result signal and remotely transmit the result signal to a staff member.
[0023] By adopting the above technical solution, the result signal can be transmitted remotely, making it convenient for staff to check.

At least four pressure sensors 22 are installed on each ranging plate 21, and the four pressure sensors 22 are installed on the four corners of the lower end surface of the ranging plate 21. The pressure sensors 22 are used to detect the pressure exerted on the ranging plate 21 and obtain a pressure signal. In this embodiment, the pressure sensors 22 can be pressure sensors.
[0035] Reference Figure 2, multiple distance measuring plates 21 are distributed along the direction of the transport vehicle driving onto the load platform 13, that is, the distribution direction of the distance measuring plates 21 is parallel to the length direction of the load platform 13, the direction parallel to the length direction of the distance measuring plates 21 and the load platform 13 is the length direction, and the direction perpendicular to the length direction of the distance measuring plates 21 and the load platform 13 is the width direction. In this embodiment, the width of the distance measuring plates 21 is greater than the length, and the length of the distance measuring plates 21 itself is less than the minimum wheelbase of the transport vehicle model adapted to the load platform 13. For example, the load platform 13 can adapt to three large transport vehicles, and the wheelbases of the three large transport vehicles are 1m, 1.1m, and 1.2m respectively, then the length of the distance measuring plates 21 needs to be less than or equal to 1m.
[0036] Reference Figure 1 and Figure 2 A lifting groove 132 is provided on the upper end surface of the carrying platform 13, and the lifting groove 132 is located at the end position of the length direction of the carrying platform 13. The intercepting plate 11 is lifted and lowered in the lifting groove 132, and a control member 12 for controlling the lifting and lowering of the intercepting plate 11 is also installed at the bottom of the lifting groove 132. In this embodiment, the control member 12 can be a cylinder, and the telescopic rod of the control member 12 is connected to the lower end surface of the intercepting plate 11. The telescopic rod of the control member 12 is lifted up and down along the opening direction of the lifting groove 132. When the telescopic rod of the control member 12 controls the intercepting plate 11 to descend to the lowest position, the upper end surface of the intercepting plate 11 and the opening surface of the lifting groove 132 are flush with the upper end surface of the carrying platform 13, and the intercepting plate 11 is used to block the front wheels of the transport vehicle.
[0037] Reference Figure 1 and Figure 2 Two inclined blocks 15 are installed on the edge of the load-bearing platform 13. The two inclined blocks 15 are respectively installed at the two ends of the length direction of the load-bearing platform 13. The upper end surface of the inclined block 15 is inclined.

[0038] The ranging module 2 includes a processor 23 for data processing and a database 24 for storing data and for the processor 23 to call. The database 24 is used to store threshold data such as weight threshold and position data of the pressure sensor 22.

When the alarm module 3 receives the result signal indicating overweight, it outputs the corresponding alarm signal. In this embodiment, the alarm module 3 can use a device that emits color light or sound, such as a color lamp or a buzzer. After receiving the result signal, the transmission module 31 remotely outputs the result signal to a designated terminal device for viewing by the staff.
[0040] The processor 23 may include a central processing unit such as a CPU or MPU or a host system built around a CPU or MPU, including hardware or software. After the meter has a processor 23, people can freely control the metering instrument by programming so that it can run according to people's wishes.

[0042] The implementation principle of a weighbridge in the embodiment of the present application is as follows: when a transport vehicle presses on the inclined block 15 and opens onto the load platform 13, the rising sensor 151 detects pressure, obtains a rising signal and outputs it to the processor 23, the processor 23 outputs a result signal indicating the rise to the control component 12, and the control component 12 lifts the interception plate 11 to block the transport vehicle after receiving the result signal. When the driver feels that the front wheel is blocked, the vehicle stops. At this time, the wheel presses on the distance measuring plate 21, and a distance measuring plate 21 is pressed by at most two wheels on the same axle. At this time, multiple pressure sensors 22 obtain multiple pressure signals, and the processor 23 then obtains the pressure signal from the database. The position data is read from the calculation to obtain the position of the axle. For example, if the four pressure signals are 5000N, 5000N, 10000N, and 10000N, and the position data of the four pressure sensors 22 are (0,0), (4,0), (0,1), and (4,-1), respectively, since the length direction of the axle is parallel to the width direction of the distance measuring plate 21, the four pressure sensors 22 can be equivalent to two for calculation, and the coordinates of the axle are the coordinates of the contact between the wheel and the distance measuring plate 21. Assuming that the position coordinates of the axle are x and the pressure of the wheel are y, the formula can be obtained: Therefore, it can be obtained that x=2 / 3, y=15000, so the position of the axle is on the axis (0.67,0) of the distance measuring plate 21, and the length direction of this axis is parallel to the length direction of the distance measuring plate 21. The positions of other axles can be calculated based on other pressure signals, and then the spacing between adjacent axles can be calculated. Combined with the vehicle model threshold stored in the database 24, the vehicle model data can be obtained. The vehicle model data obtained by combining the model threshold can be obtained by table lookup, for example (the spacing between adjacent axles is 1m, 2m, 1m, 1m, respectively, and the model is A), (the spacing between adjacent axles is 1.1m, 2m, 1.1m, 1.1m, respectively, and the model is B). At this time, the vehicle model data can be obtained by table lookup based on the spacing between adjacent axles; by carrying the sensor element 14 performs pressure detection on the entire load-bearing platform 13 to obtain weight data, and then obtains the weight threshold value from the database 24 by table lookup according to the vehicle model data, and then compares the weight data with the weight threshold value to determine whether the transport vehicle is overweight. If it is not overweight, a result signal indicating that it is not overweight is output to the control component 12, and the control component 12 controls the interception plate 11 to descend for the transport vehicle to pass. At this time, the transport vehicle presses over the inclined block 15 to open the load-bearing platform 13, and the rising sensor 151 is pressurized again to obtain a rising signal to the processor 23. When the rising sensor 151, the pressure sensor 22 and the load-bearing sensor 14 are not pressurized, it indicates that the transport vehicle has left. At this time, the processor 23 outputs a result signal to the control component 12, and the control component 12 controls the interception plate 11 to rise to block the next transport vehicle.
[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
