Embodiment 1

[0024] Such as figure 1 As shown, the cable well safety operation monitoring system and monitoring method based on network communication technology include an on-site module 1 installed in the cable well and a control module 2 remotely connected to the on-site module. The on-site module and the control module are connected through a network communication device 3 connections, the local module 1 includes an acquisition unit 2, a monitoring unit 3 and an alarm unit 4, the control module 2 includes a server 5 and a data processor 6 connected thereto, and a memory 7, and the network communication device includes a transmission unit 8 and an information exchange interface 9.

[0025] The acquisition unit includes an environmental information acquisition unit and a cable operation information acquisition unit. The environmental information acquisition unit includes a vibration sensor 10, a smoke sensor 11, and a temperature sensor 12 distributed in the cable shaft. The cable operati...

Embodiment 2

[0032] The cable well safety operation monitoring system and monitoring method based on network communication technology are different from Embodiment 1 in that the infrared camera is installed with a preset pan / tilt, and the load-bearing of the pan / tilt is considered when selecting, that is, the support of the protective cover. Total weight, emergency LED lighting and temperature control and alarm devices are installed in the outer protective cover to ensure the safe operation of the instrument. The user can set multiple pre-selected observation positions for the preset pan / tilt, which is convenient for the device to work on the power equipment automatically or manually. status monitoring.

[0033] At the same time, since the infrared image does not conform to the human visual system, the monitoring device can also add a visible light camera, use the fusion technology of visible light and infrared image, through image registration and data fusion, to obtain a composite image w...

Embodiment 3

[0038] The cable shaft safety operation monitoring system and monitoring method based on network communication technology are different from Embodiment 1 or 2 in that the temperature measurement module for measuring the core temperature at the cable joint is made of bimetallic temperature measurement material, and the temperature measurement module includes The temperature-sensing bimetal, single-chip microcomputer, analog-to-digital conversion chip and signal filter device mainly express the temperature signal in the form of a current signal, and then send it to the single-chip microcomputer for sampling after filtering, amplification and analog-to-digital conversion. Since the temperature measurement module will be interfered by a lot of clutter or power frequency noise during the temperature sampling process, a low-pass filter can be set to ensure the accuracy of the signal, and then the filtered signal will be amplified to achieve subsequent processing module call.

Abstract

The invention provides a cable well safety operation monitoring system and monitoring method based on the network communication technology. The system comprises an on-site module installed in a cable well, and a control module remotely connected with the on-site module. The on-site module is connected with the control module through a network communication device. The on-site module comprises a collecting module, a monitoring unit and an alarming unit. The control module comprises a server, a data processor and a memorizer, wherein the data processor and the memorizer are connected with the server. The network communication device comprises a transmission unit and an information exchanging interface. By means of the cable well safety operation monitoring system and monitoring method, various types of environment information in the cable well can be monitored, all-direction monitoring can be carried out on the cable running information, an improved suggestion or scheme can be generated according to the monitoring information, and a reliable basis and scheme are provided for a management target of the intelligent cable well detection.

Description

technical field [0001] The invention relates to the technical field of cable well safety operation monitoring, in particular to a cable well safety operation monitoring system and a monitoring method based on network communication technology. Background technique [0002] The cable well is a node closely related to people's production and life in the power system, and it plays a huge and irreplaceable role. With the rapid development of urbanization, the cable derrick has become the main component of the urban power grid. In order to ensure reliability and continuously improve the safety margin, the cost of line construction has been increasing year by year. However, in actual work, there are still many cables running with faults, causing explosions, fires and other accidents, causing huge losses and impacts on the power sector and society. [0003] The Chinese patent with the application number 201020632038.8 relates to an intelligent cable trench and well online monit...
