[0034] Specifically, support rods 1 are set at the vehicle parking line positions on both sides of the weighing scale, and a detection module 5 is set at the upper end of the support rod 1. After the driver parks the vehicle, the information of the radio frequency card is identified by the identification module 51, and the corresponding radio frequency card information and vehicle weight information are stored in the computer controlling the weighing scale through the communication module 52. After the vehicle is loaded or unloaded, the radio frequency card information and vehicle weight information are obtained again through the detection module 5 on the other side, and compared with the first time, the actual cargo capacity is obtained.

[0035] In this way, by installing the detection module 5, the computer controlling the scale automatically obtains the vehicle corresponding to the weight information measured by the matching scale, and broadcasts the weight through the broadcast module 53, thereby increasing the speed of the vehicle passing through the scale and improving work efficiency.

[0036] It should be understood that during weighing, the driver is located inside the vehicle. The upwardly opening card insertion port 3 is provided, and the driver inserts the card from top to bottom. The side closest to the driver is also provided with an outwardly flared curved surface to facilitate card insertion. Floor scales are often located outdoors. To prevent rainwater from affecting the detection module 5, the detection housing 4 is a sealed housing, and multiple water-permeable holes are provided at the bottom of the outer housing 2. Rainwater entering the card insertion port 3 flows out through the water-permeable holes. The weight is also broadcasted by the announcement module 53, allowing the driver to obtain weight information and promptly detect any errors or overloading.

[0037] In some feasible embodiments, the support rod 1 is in the shape of a rectangular rod, and the bottom of the support rod 1 is fixedly connected to the floor scale by bolts. The two support rods 1 are respectively arranged at the driver's parking positions in the two directions of vehicle entry and exit. The outer shell 2 is in the shape of a rectangular shell, and the card insertion port 3 includes a rectangular plate and an arc plate arranged relatively, and the rectangular plate and the arc plate are between the card insertion channel. The side of the detection shell 4 used for detection is parallel to the rectangular plate, and the rectangular plate is identified after the radio frequency card is inserted.

[0038] The detection module 5 includes an identification module 51, a communication module 52, and a broadcast module 53. The identification module 51 is a radio frequency card reader module. The communication module 52 establishes a connection with the computer that controls the weighing scale via wireless or wired signals. The radio frequency card can store information such as the vehicle's driver and license plate number. The communication module 52 transmits this information to the computer and records the corresponding weight information. The identification module 51 and the communication module 52 are both integrated modules of the prior art and will not be described in detail here. The broadcast module 53 includes a loudspeaker that obtains the weighing information through the communication module 52 and broadcasts it, allowing the driver to check and remind the driver that the weighing is complete.

[0039] As a specific implementation of an RFID card reader provided in the application, please refer to Figure 2 The support rod 1 includes a base rod 11, which is fixedly installed on the floor scale. A gear rod 12 is slidably installed in the base rod 11. A drive motor is fixedly installed on the upper end of the base rod 11. The output end of the drive motor is connected to a drive gear 13 that engages with the gear rod 12. The outer shell 2 is installed on the upper end of the gear rod 12.

[0040] In combination with specific usage scenarios, different trucks carry different cargo, and the corresponding driver's height is different. By setting a liftable support rod 1, it is easy to adjust the height of the support rod 1 to adapt to the use of different vehicles.

[0041] Furthermore, infrared sensing modules 54 are provided at both upper and lower ends of the outer shell 2 . The infrared sensing modules 54 are electrically connected to the driving motor. When the infrared sensing modules 54 are blocked, the driving motor drives the outer shell 2 to move in the blocked direction.

[0042] It should be understood that by setting up the infrared sensing module 54, when the height of the support rod 1 is not appropriate, the driver can block the signal of the infrared sensing module 54 by extending his hand, so that the drive motor drives the outer shell 2 to move in the blocked direction, which is convenient for the driver to adjust the support rod 1 independently and more convenient for the driver to use.

[0043] In some feasible embodiments, the base rod 11 is a rectangular rod, and a rectangular mounting box is fixedly installed on the upper end of the base rod 11. The driving gear 13 and the driving motor are installed in the mounting box. The gear rod 12 is a rectangular rod with one side set as a toothed surface. After passing through the mounting box, it can be slidably inserted into the base rod 11.

[0044] As a specific implementation of an RFID card reader provided in the application, please refer to Figure 1 and Figure 3 A plurality of connecting columns 21 are installed in the outer shell 2, and a sliding column 22 is slidably installed on the connecting column 21. A return spring 23 is provided between the connecting column 21 and the sliding column 22. The sliding column 22 is fixedly connected to the detection shell 4, and the connecting column 21 is perpendicular to the inserted radio frequency card.

[0045] It should be understood that after the RFID card is inserted, it approaches the identification module 51, thereby generating an induced current to interact with the identification module 51. By setting the sliding column 22 and the return spring 23, the detection shell 4 can be tightly fitted with the RFID card after the RFID card is inserted, which facilitates the acquisition of information.

[0046] Furthermore, a position sensor 55 is fixedly installed on the bottom of the detection housing 4 near the radio frequency card, and the position sensor 55 is electrically connected to a buzzer.

[0047] It should be understood that by setting the in-place sensor 55, after the radio frequency card is inserted into place, the buzzer will sound to remind the driver to insert the card into place, so as to facilitate the recognition module 51 to identify it.

[0048] In some feasible embodiments, the position sensor 55 may be an infrared sensor module.

[0049] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
