Embodiment

[0050] Such as figure 2 As shown, a narrowband wireless signal monitoring device for load management terminal detection includes a radio station 1, a modem 2, a main control unit 3 and a display 4, and the main control unit 3 is respectively connected to the radio station 1, modem 2 and display 4, so The station 1 described above is connected to the modem 2. Considering that the communication between the terminal and the main station mainly depends on the narrowband radio signal with a frequency of 230MHz, a radio station, a modem, a main control unit, and a display are combined to form a monitoring device capable of receiving narrowband radio signals with a peripheral frequency of 230MHz. The basic working principle is: under the control of the main control unit, the radio station and the modem receive space signals, analyze the signals, and transmit the signals to the supporting software for storage for analysis and judgment.

[0051] Station 1 adopts a conventional digita...

Abstract

The invention relates to a narrow-band wireless signal monitoring method and a device thereof for detecting a load management terminal. The method comprises the following steps of: 1) a master control unit selects a broadcasting station channel, sets a broadcasting station working mode and sets the frequency deviation of a modem; 2) the broadcasting station carries out space exploration to a narrow-band wireless signal, captures a message signal transmitted between a master station and the load management terminal, and transmits the message signal to the modem for analysis; and 3) the modem transmits the analyzed signal to the master control unit, and the master control unit monitors and stores the analyzed message information according to the broadcasting station working mode, and transmits the analyzed message information to a display. The device comprises the broadcasting station, the modem, the master control unit and the display, wherein the master control unit is respectively connected with the broadcasting station, the modem and the display, and the broadcasting station is connected with the modem. Compared with the prior art, the method and the device are characterized by that the communication technology is combined with the computer software and hardware technology, and the signal can be effectively monitored without interference in real time in the detection process.

Description

technical field [0001] The invention relates to radio communication technology, computer software, and microchip hardware technology in load management terminal detection, in particular to a narrowband wireless signal monitoring method and device for load management terminal detection. Background technique [0002] The load management terminal (hereinafter referred to as the terminal) is a reused component in the power load management system. It is used to implement data collection, control, monitoring, meter reading, etc. for the power consumption of the client. It is a set of multiple control and management functions. In-situ installation. The integrity and stability of terminal functions will directly affect the operation performance of the entire load management system, so performance testing and quality control of network-connected terminals will be a very important step. The detection work is carried out in a simulation environment that simulates the actual master sta...
