Embodiment 1
[0026] Such as figure 1 As shown, this embodiment provides an electronic scale identification system, including a detection device 1 and an electronic scale 2 . The detection device 1 is provided with a display, a transmitter, and a data receiving unit; the display can be a display screen, or a device that can display data verification results such as an indicator light. The transmitter can be an infrared receiver, and the communication is realized through an infrared carrier. The data receiving part is an infrared receiving part, and the communication is realized through an infrared carrier. The electronic scale 2 is provided with a receiver and a data sending part, and the receiver can also be an infrared receiver, and the communication is realized through an infrared carrier. The data sending part can also be an infrared sending part, and the communication is realized through an infrared carrier. The electronic scale sets a program on the chip that responds to the access...

The invention relates to the field of electronic scale management, and provides an electronic scale identity recognition system which comprises an electronic scale and a detection device. The electronic scale is provided with a receiver and a data sending part; the detection device is provided with a display, a transmitter corresponding to the receiver and a data receiving part corresponding to the data transmitting part; the electronic scale is provided with a program which responds to access of the detection device and outputs verification data, and the detection device is provided with a corresponding program internal code; and the display is used for displaying the result of the verification data. Through the technical scheme of the detection device, the electronic scale, the program, the machine code, the data encryption and decryption processing device, the display device and the like which are matched with one another, the detection result accuracy is high, the program is not easily tampered, in addition, a user can use the system without professional skills, the operation is simple, and the user can identify whether the electronic scale is tampered or not only by using the detection device to irradiate the electronic scale.
Description
technical field [0001] The invention relates to the field of electronic scale management, and more specifically, to an electronic scale identification system. Background technique [0002] Today's common electronic scale tampering method is to change the pin (I / O port) level of the MCU by tampering with the main chip (MCU) program of the electronic scale, by adding a remote control circuit or directly pressing a button from the keyboard, according to I / O port level status, jump to the tampering program to run, and get the tampering result. It is very convenient to exit the tampering program and return to normal through the remote control or keyboard. In such a situation, it is difficult for regulators to find evidence of tampering. [0003] For electronic scales equipped with remote tampering devices, the additional circuits can be found after dismantling the machine, and the manufacturer's technical verification and verification report can be used as an auxiliary basis f...
