Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of floor scales, in particular to a floor scale device with a monitoring function. Background Art
[0002] Weighbridge, also known as truck scale, is a large scale installed on the ground. It is usually used to weigh the tonnage of truck cargo. It is the main weighing equipment used for bulk cargo measurement in factories, mines, and businesses. Weighbridge can be divided into I-beam weighbridge, T-beam weighbridge, L-beam steel weighbridge, U-beam weighbridge, channel steel weighbridge, reinforced concrete weighbridge according to the scale structure. It can be divided into digital weighbridge and analog weighbridge according to the sensor type.
[0003] The floor scale includes a weighing platform with a weighing sensor arranged underneath. When a vehicle enters the weighing platform, the vehicle's gravity causes the elastic body of the weighing sensor to undergo elastic deformation, causing the impedance of the strain gauge bridge attached to the elastic body to lose balance, thereby outputting an electrical signal proportional to the weight value. The signal is then processed by the amplifier, A / D converter, microprocessor and other electronic components inside the sensor to output a digital signal, which is then transmitted through a repeater to the weighing display instrument to directly display the weight and other data.
[0004] With respect to the above-mentioned related technologies, the applicant believes that in the related technologies, when the driver drives the vehicle onto the scale for weighing, it is inconvenient for the driver to determine whether the vehicle is completely located directly above the scale due to the driver's blind spot. Sometimes the vehicle does not completely drive onto the scale, resulting in inaccurate weighing data of the vehicle. Therefore, manual supervision of the vehicle weighing process is usually required, which takes up human resources. Utility Model Content
[0005] The utility model aims to provide a floor scale device with a monitoring function, which can replace manual monitoring of weighed vehicles to a certain extent, thereby helping to reduce the occupation of human resources.
[0006] The utility model is realized by the following technical solutions:
[0007] A floor scale device with a monitoring function includes a weighing platform and a weighing sensor located below the weighing platform, a controller and an alarm device. The weighing platform is provided with pressure plates on the ground at both ends along the direction of vehicle travel, and both of the pressure plates are close to the weighing platform. Pressure sensors are provided below the two pressure plates. The pressure sensors, weighing sensors and alarm device are electrically connected to the controller respectively. The alarm device is used to alarm when the vehicle is pressed on the pressure plate.
[0008] Furthermore, license plate recognition cameras are arranged on the ground at both ends of the weighing platform along the vehicle's traveling direction, one of the license plate recognition cameras is used to recognize the license plate number at the front end of the vehicle, and the other license plate recognition camera is used to recognize the license plate number at the rear end of the vehicle, and the license plate recognition cameras are electrically connected to the controller.
[0009] Furthermore, barrier gates are provided on the ground at both ends of the weighing platform along the vehicle travel direction, and the barrier gates are electrically connected to the controller.
[0010] Furthermore, it also includes a weighing printer arranged on one side of the weighing platform, and the weighing printer is electrically connected to the controller.
[0011] Furthermore, a mounting platform is provided on the ground at one end of the weighing platform along the vehicle travel direction, the weighing printer is located on the mounting platform, and the weighing printer is located on the side of the weighing platform close to the driver of the vehicle after loading.
[0012] Furthermore, a protective shed is provided on the mounting platform, and the protective shed is used to shield the weighing printer.
[0013] Compared with the prior art, the utility model has the following advantages and beneficial effects:
[0014] 1. When the vehicle is weighed, if the tires of the vehicle are pressed on the pressure plate, it means that the vehicle has not yet completely driven to the top of the weighing platform. The pressure sensor transmits the signal to the controller, and the controller controls the alarm device to send an alarm signal to remind the vehicle driver that the vehicle has not completely driven to the weighing platform until the tires of the vehicle are away from the pressure plate and all the tires of the vehicle are on the weighing platform between the two pressure plates. At this time, the alarm device stops the alarm and the weighing operation can be started. To a certain extent, it replaces the manual supervision process of the weighed vehicle, reduces the waste of human resources, and can facilitate the driver to weigh the vehicle correctly.
