AI Technical Summary

Problems solved by technology

[0004] Among the existing public mobile inspection methods, there are also wireless networks, such as ZIGBEE networks, which generate low-precision synchronization signals. The data measured by this method has low synchronization accuracy, single trigger mode, no phase synchronization, and limited application range.
[0005] There are also existing ones that use GPS as a synchronization signal, such as patent CN103364698B, which uses a wireless sensor network and cooperates with GPS to generate a synchronization signal. This measurement method does not have phase synchronization, and its application has limitations.

Embodiment Construction

[0023] According to the difference between the detection mode of the phase acquisition module and the measurement mode of the patrol measurement module, the present invention can form different applications, such as partial discharge patrol inspection device and vibration patrol inspection device.

[0024] The partial discharge inspection device will be described below as an embodiment of the present invention.

[0025] The partial discharge inspection device is used to collect the data of partial ionization discharge of 50HZ high voltage, and its data can be used to analyze and locate insulation faults.

[0026] In this embodiment, the phase acquisition module is specifically used for power frequency zero-crossing point detection and outputs zero-phase pulses, which is called the power frequency phase acquisition module (103); the patrol measurement module is specifically used for detecting and measuring the ionization discharge pulse signal of high-voltage electricity , call...

Abstract

The invention relates to a wireless routing inspection apparatus with phase synchronization, which belongs to the technical field of electronic communication, and is applied to the field of intelligent instruments. The wireless routing inspection apparatus comprises a phase reference apparatus and a moving routing inspection apparatus. The phase reference apparatus adopts phase information of a reference and synchronizes with the moving routing inspection apparatus by virtue of a wireless phase synchronization main module, a wireless phase synchronous slave module in the moving routing inspection apparatus outputs a synchronous phase signal to a measurement module, and the measurement module acquires data according to the synchronous phase signal.

Description

technical field [0001] The invention belongs to the technical field of electronic communication and is applied to the field of intelligent instruments. Background technique [0002] The wireless inspection device is an instrument used for daily inspection of equipment operation status. By collecting information such as vibration, temperature, humidity, pressure, stress, light, voltage, current, electromagnetic field and other information of equipment, it assists technicians in judging the operation status of equipment and predicting Fault hidden dangers, predicting fault types and locating fault locations. [0003] Existing wireless inspection devices generally only have the function of data collection, and personnel hold the device to collect data at a possible fault point. This kind of data has no time information and phase information, which brings uncertainty to the judgment of faults. [0004] Among the existing public mobile inspection methods, some are based on wirel...
