Example Embodiment

[0030] Embodiment 1 is basically as attached figure 1 Shown: An intelligent prevention and control method for metering prevention and control, including the following steps:

[0031] In the scanning and receiving step, the radio wave signal within the width of the target frequency band (100-1000MHz) is divided into three separated signal frequency bands, and three FM receiving modules corresponding to the signal frequency bands are set up, and the FM receiving modules periodically check the corresponding signal frequency bands. The radio signal is continuously sampled and received as an integer value. The continuous integer value can be understood as dividing 100-1000MHz into 901 integer values, and each FM receiving module only periodically receives the radio signals of these 300 (or 301) integer-valued frequencies. Each FM receiving module is connected to a corresponding processing module, and the processing module analyzes the signal strength received by the corresponding ...

[0045] Example 2

[0046] Compared with Embodiment 1, the only difference is that between the interference determination step and the alarm prompt step, a high voltage protection step is also included. After the review processing module determines that the weighing result has been modified, the storage module, the single-chip microcomputer and the weight sensor The two ends are respectively grounded, and the circuit between the weight sensor and the storage module, the storage module and the single-chip microcomputer uses piezoelectric ceramics for high-voltage stimulation.

[0047] In this embodiment, a system for implementing the above method is also disclosed. Compared with the system in Embodiment 1, the only difference is that it also includes a high-voltage protection module, which is arranged between the weight sensor and the storage module. 1. On the circuit between the storage module and the single-chip microcomputer, after the review processing module determines that...

[0048] Example 3

[0049] Compared with Embodiment 1, the only difference is that a central processing module is selected, and the specific signal can be selected from the I3 series processing chip of the existing PC computer, plus some peripheral circuits. Of course, in the present embodiment, the adopted It is a PC computer, and the processing module corresponding to each FM receiving module is respectively connected to the PC computer, so that the PC computer is connected to the display module, and the display module displays the frequency of the signal currently judged as environmental interference. Setting up a PC can make the work of each FM receiving module more coordinated, avoiding the same situation where multiple FM receiving modules require the transmitting module to transmit interference signals of different frequencies at the same time, so that the computing power of the PC can be used.

Abstract

The patent belongs to the field of wagon balance control, and specifically discloses an intelligent control method for controlling measurement aiming at the technical problem that an existing measurement control instrument is slow in scanning speed and easy to misreport when executing scan with the frequency bandwidth width of 100-1000MHZ. The method comprises the following steps of a scan receiving step, specifically including dividing an electric wave signal into at least two signal frequency bands in a target frequency bandwidth width, and setting frequency modulation receiving modules corresponding to the signal frequency bands, wherein the frequency modulation receiving modules periodically perform continuous sampling and receiving on the electric wave signals within the corresponding signal frequency bands, respectively, each frequency modulation receiving module is connected with a corresponding processing module, each processing module analyzes the strength of the signal received by the corresponding frequency modulation receiving module, and when the strength of the electric wave signal at specified frequency exceeds a threshold, the processing module analyzes the electric wave signal at the frequency; a scan determination step; an interference prevention and control step; and an interference determination step.

Description

technical field [0001] The invention relates to the field of weighbridge prevention and control, in particular to an intelligent prevention and control method for metering prevention and control. Background technique [0002] At present, all enterprises and factories that need to weigh goods involving steel, coal, cement, etc. will use weighbridges to measure. But now some criminals, driven by profit, spend a lot of money to develop a device that can remotely control the weighbridge, so that the displayed data can be increased or decreased, so as to achieve the purpose of making huge profits. [0003] The weighbridge mainly uses a pressure sensor (or strain gauge bridge, weight sensor or load cell, etc.) to convert the measured weight into electricity and transmit it to the single-chip microcomputer, and then the single-chip microcomputer drives a display device to display the weight. come out. Lawbreakers secretly install a receiving device between the tablet sensor and t...
