Description

Power consumption information acquisition interactive communication detector

Technical Field

The utility model relates to the technical field of power consumption information acquisition terminals, in particular to a power consumption information acquisition interactive communication detector.

Background

The demand of people in modern society for automation and intellectualization is higher and higher, and an electricity consumption information acquisition system is constructed comprehensively, so that all power users and gateways can be covered comprehensively, the online monitoring of the electricity consumption information of the users by a metering device is realized, and basic data is provided for related systems timely, completely and accurately. Along with the continuous construction of the electricity consumption information acquisition system, more and more acquisition terminal devices are arranged in the system, and the workload of newly assembling, operating and maintaining field devices is also larger and larger.

The uplink communication of the acquisition terminal mainly uses four networks, namely a public network of three operators of China Mobile, China Unicom and China telecom and a 1.8G electric power wireless private network, and the signal intensity basically meets the communication requirement of the acquisition terminal. In the process of newly installing, operating and maintaining a field terminal, because the fault processing workload caused by the signal problem accounts for more than 50%, the previous signal processing problem mainly depends on experience or adopts an elimination method of replacing equipment, an effective test link is lacked for invisible signals, details such as whether the signals reach the standard, whether the antenna installation position is reasonable, whether the feeder loss is overlarge and the like are fuzzy, and a series of subsequent weak signal and no signal faults are often caused.

The existing signal measuring instruments comprise field intensity instruments, frequency spectrometers and other equipment, which are widely used by companies outside the power industries such as mobile, telecommunication, Unicom, broadcasting and television, but the equipment has poor universality in the field of power wireless communication, and part of the equipment has large volume and is inconvenient to carry due to alternating current power supply. The existing measuring instrument can only test the signal intensity, has some defects in functions of full signal measurement, signal pre-response test, pre-response interaction and the like, and is very inconvenient to carry a plurality of signal measuring instruments to a site during application.

And (3) full signal measurement: in the scene is used on the scene, collection terminal uses operator public network and the wireless private network of 1.8G electric power to go upward the communication, can't know in advance which kind of network of this use can ensure terminal normal communication in the installation maintenance process, can only pass through experience in the past or change the SIM card test by one, lead to the waste of manpower and materials time, also bring great work degree of difficulty for inexperienced new staff.

Signal preconditioning test: in a field application scene, part of terminals are installed in a basement, and no communicable signal exists in the basement, so that the terminal antenna cannot be installed in the basement, and the antenna needs to be led to the ground through a long signal extension feeder to be installed. When an extension line is placed, the situation that signal attenuation is too large due to too long extension feeder lines often occurs, and the stability of terminal communication is affected.

Signal pre-answer test: in a field application scene, after part of terminals are subjected to signal testing, it is found that the testing values are more critical and may be different, and accurate judgment cannot be made, so that whether the antenna can be installed cannot be determined. If the terminal and the acquisition system cannot normally communicate after the antenna feeder is installed subsequently, the antenna needs to be reworked, and the field workload is greatly increased.

Through market research, no detection instrument capable of simultaneously measuring three public network operator signals and 1.8G power wireless private network signals exists in the current market, application layer message communication interaction with a power utilization acquisition system master station cannot be realized, and a plurality of problems such as power uplink communication protocols cannot be supported. At present, no special detecting instrument for testing the electric information acquisition terminal signal exists.
