Embodiment Construction
[0014] The technical scheme adopted by the present invention to solve the technical problem includes two parts of hardware and software.
[0015] Hardware part: The main control and processing system controller of this system adopts TI company's digital signal controller TMS320F2812, which has 120MHz high-speed processing capability, 32-bit processing unit, and 32-bit cumulative operation in a single instruction cycle, which can meet the needs of applications for faster code development Processor performance requirements with integrated advanced controllers. Taking the six tube parent displacement monitoring points as an example, the overall block diagram of the system is shown in Figure 3. It mainly includes (1) main control and processing unit module, (2) auxiliary control and processing unit module, (3) laser ranging module, (4) temperature and humidity measurement module, (5) industrial computer. Communication between modules: RS485 communication is used between (1) and (...

The invention relates to a method for monitoring overhead tube bus displacement and provides a supporting type overhead tube bus displacement monitoring device and a monitoring method. Infrared laser is transmitted to a reflector through a laser infrared distance measurement sensor, a distance between a tube bus end and a laser head is measured, and the tube bus horizontal displacement amount is measured through calculation. A calculation formula is (shown in description). The supporting type overhead tube bus displacement online monitoring method can check thermal-stretching cold-contraction change data and a curve of a tube bus within a time period on the ground in real time, establish a mathematic model, perform pre-warning on stuck phenomena occurred between the bus and a wire clamp and between an expansion joint and the wire clamp due to thermal stretching and cold contraction of the tube bus and detect whether the tube bus can freely perform thermal stretching and cold contraction on the wire clamp or not.
Description
technical field [0001] The invention relates to a displacement monitoring system of a support type overhead pipe parent. Background technique [0002] Most of the high-voltage substations are unattended. The power station has multiple sections of tube brackets. Under the influence of different climates (such as high temperature, heat, rain, snow and freezing), the tube brackets move due to thermal expansion and contraction. The friction between the tube brackets and the brackets will cause the lower The supporting porcelain bottle is subject to greater stress, which shortens the service life of the porcelain bottle. [0003] The existing method for monitoring the displacement of the tube parent is mainly to indicate the position of the tube parent by installing a self-made dial and pointer for manual observation. Due to the high position of the pipe mother and the strong electric field environment, considering the safety factor, the telescope is often used to observe the po...
