[0052] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0053] Figure 1 is a structural schematic diagram of a vehicle scale weighing detection system provided by an embodiment of the present invention, such as Figure 1As shown, the system includes: an external monitoring device 10, a weighing module 20 and a track robot 30; the external monitoring device 10 is connected to the weighing module 20 for communication, and the weighing module 20 is connected to the track robot 30 for communication; the external monitoring device 10 is used to identify the vehicle information of the vehicle to be weighed and the external moving object in the weighing area; the weighing module 20 is used to determine whether the weighing requirements are met according to the vehicle information; if the weighing requirements are met, the gate is controlled to open; and when a weight signal is detected, a detection instruction is sent to the track robot 30;

[0054] The track robot 30 includes at least one extending detection arm 31 and an in-vehicle personnel detection module 32; the in-vehicle personnel detection module 32 is arranged on the extending detection arm 31; the track robot 30 is used to open the extending detection arm 31 according to the detection instruction so that the in-vehicle personnel detection module 32 can detect whether there is a person getting off the vehicle; the weighing module 20 is used to determine the weighing data of the vehicle to be weighed when the in-vehicle personnel detection module 32 detects that a person has got off the vehicle and the external monitoring device 10 has not identified an external moving object in the weighing area.

[0055] The external monitoring device 10 may be a radio frequency identifier or an external monitoring camera; the external monitoring device 10 may be used to identify the vehicle information of the vehicle to be weighed and the external moving objects in the weighing area; the vehicle information includes the vehicle license plate information and the vehicle material information; the weighing area is a standard weighing area designated for the vehicle to be weighed;

[0056] The weighing module 20 can be a digital weight sensor system that uses the principle of strain gauge measurement for weighing. The weighing module 20 can first read the vehicle information, such as the license plate information of the vehicle, and retrieve the weighing plan according to the license plate information of the vehicle; when the weighing plan meets the weighing requirements; control the gate to open; the vehicle to be weighed enters the weighing platform; when the weighing module 20 detects the weight signal, it sends a detection instruction to the rail robot 30. Among them, the weighing principle of the weighing module 20 is specifically as follows: a strain gauge is attached to the elastic body of the weighing sensor to form a Wheatstone bridge. When there is no load, the bridge is in a balanced state and the output is zero. When the elastic body is subjected to a load, each strain gauge will generate a strain proportional to the load, and the weight value loaded on the weighing platform can be measured by the output voltage.

[0057] The in-vehicle personnel detection module 32 in the track robot 30 can be an infrared detector, an ultrasonic radar, a camera, etc.; a plurality of extendable detection arms 31 can be provided according to different detection angles to improve the flexibility of the track robot; the specific number of the extendable detection arms 31 is not limited here.

[0058] In the prior art, infrared detectors, ultrasonic radars, or cameras are used to detect people inside the car from outside the car; when using infrared detectors to detect people inside the car, due to the influence of the external environment, when the ambient temperature and the human body temperature are close, the infrared radiation of the human body is easily blocked, which reduces the accuracy of the infrared detector in detecting people; or when using ultrasonic radar to detect people inside the car, due to the influence of the external environment, the resolution of the ultrasonic radar is poor, resulting in a decrease in the accuracy of the ultrasonic radar in detecting people; or when using a camera to detect people inside the car, the camera has high requirements for external light, resulting in a decrease in the accuracy of the camera in detecting people; in this solution, the track robot 30 opens the extension detection arm 31 when receiving the detection instruction, extends the extension detection arm 31 into the car, and uses the car occupant detection module 32 to detect whether there are people getting off the car. The process of detecting people inside the car avoids the influence of the external environment, thereby improving the detection accuracy of people in the cab. At the same time, when the in-vehicle personnel detection module 32 in the rail robot detects that someone has gotten off the vehicle and the external monitoring equipment 10 has not identified an external moving object, the weighing module 20 determines the weighing data of the vehicle to be weighed and completes the intelligent weighing of the weighing detection system.

[0065] Based on the same inventive concept, an embodiment of the present invention further provides a vehicle scale weighing detection method, which is applied to the vehicle scale weighing detection system described in the above embodiment.
