[0033]The detection alarm system 35 includes a central processing unit 36, a data recording module 37, a pressure alarm module 38, a wireless transmission module 39, a mobile terminal 40, a troubleshooting module 41 and a data storage module 42, the output terminal of the central processing unit 36 and a data recording module The input end of 37 is electrically connected, the output end of the central processing unit 36 is electrically connected to the input end of the pressure alarm module 38, the output end of the central processing unit 36 is electrically connected to the input end of the wireless transmission module 39, and the output end of the central processing unit 36 is electrically connected It is signally connected to the input end of the mobile terminal 40, the output end of the central processing unit 36 is electrically connected to the input end of the troubleshooting module 41, and the output end of the central processing unit 36 is electrically connected to the input end of the data storage module 42.
[0034]The electrical components appearing in this article are all connected to the external main controller and 220V mains power, and the main controller can be a conventional known device that controls the computer.
[0035]Working principle: When in use, first drive the detection vehicle into the support plate 2, and then the motor 20 drives the support plate 2 to move horizontally through the threaded hole 26 and the threaded rod 27, while the gear 10 drives the rack drive plate 11 to move synchronously to one side , Through the cooperation of the third sliding groove 30 and the positioning slider 31, and the cooperation of the first sliding groove 12 and the first pulley 13, the support plate 2 is more stable when it moves. While detaching from the groove 7, the clamping block 28 slides to the sliding outlet 29, and the clamping rod 23 is disengaged from the clamping groove 21 by the gravity of the vehicle, and the first spring 15, the second spring 19 and the third spring 32 pair The support plate 2 carrying the vehicle provides a more stable support. The support plate 2 is pressed down and contacted with the load cell 6, and the weight of the vehicle is detected by the load cell 6. If it exceeds the set threshold, it will pass through the data recording module 37 and data The storage module 42 records and stores, and at the same time transmits the pressure alarm signal to the mobile terminal 40 through the wireless transmission module 39, which can remotely alarm the vehicle for pressure overweight. In addition, the fault inspection module 41 can perform fault detection on the detection alarm system module 35 to Ensure the accuracy of the vehicle weight detection during each vehicle inspection, and avoid problems with the detection system that affect the weighing detection of the vehicle.
[0036]It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply one of these entities or operations. There is any such actual relationship or order between. Moreover, the terms "include", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes those that are not explicitly listed Other elements of, or also include elements inherent to this process, method, article or equipment. If there are no more restrictions, the element defined by the sentence "including a..." does not exclude the existence of other identical elements in the process, method, article, or equipment including the element.
