Weather-proof composite physical quantity collector

Abstract

The invention provides a weather-proof composite physical quantity collector. The collector comprises a joint module, an analog-to-digital conversion module, a control module and a wireless transceiving module; the joint module comprises various types of sensor connecting joints and is used for connecting each sensor and acquiring sensing signals; the analog-to-digital conversion module is connected with the joint module, receives the sensing signals and converts analog signals in the sensing signals into digital signals; the control module is connected with the analog-to-digital conversion module and is used for receiving the digital signals and converting the digital signals into physical quantities; and the wireless transceiving module is connected with the control module and is used for wirelessly transmitting the physical quantities. The system is low in power consumption, high in integration level, suitable for long-term monitoring of the field monitoring environment of a power transmission line, low in cost, just occupies small space on a tower, needs few installation and debugging procedures, needs few components and is convenient to overhaul and remove faults.

Description

technical field [0001] The invention relates to the field of on-line monitoring of power transmission lines, in particular to a weather-resistant composite physical quantity collector. Background technique [0002] With the advent of the digital power grid era, there is an increasingly urgent demand for online monitoring technology for transmission lines. The existing on-line monitoring technology of transmission lines has the following problems: First, the on-line monitoring equipment has low stability and poor weather resistance, and the online normal operation time often cannot exceed one year. Second, the operating environment of transmission lines is harsher than that of bridges, buildings and other engineering structures, while some online monitoring equipment has low precision and poor stability, while other online monitoring equipment has high costs and high tariffs for returning to the factory for maintenance, resulting in The types of on-line monitoring equipment ...

Problems solved by technology

The existing on-line monitoring technology of transmission lines has the following problems: First, the on-line monitoring equipment has low stability and poor weather resistance, and the online normal operation time often cannot exceed one year. Second, the operating environment of transmission lines is harsher than that of bridges, buildings and other engineering structures, while some online monitoring equipment has low precision and poor stability, while other online monitoring equipment has high costs and high tariffs for returning to the factory for maintenance, resulting in The types of on-line monitoring equipment that are truly suitable for transmission lines are scarce; third, the equipment integration is not high, and the connection and installation method is not suitable for the structure of the transmission line body; fourth, the power consumption of the equipment does not match the installed power supply system, resulting in rechargeable batteries. Unreasonable use reduces the time for stable system operation
