Telemetry remote control system remote control lifting bracket

Time：2020-11-13 View：

Telemetry remote control system is one of the systems needed by remote control lift rod. Use telemetry technology to realize remote measurement, control and monitoring system. In the telemetry remote control system, the measuring device and actuator are set near the controlled object, and the measured values of the controlled object parameters are sent to the remote measurement and control station through the telemetry channel, the control command of the measurement and control station is also sent to the actuator through the telemetry channel.

 

Basic knowledge

 

Telemetry
The technology of transmitting the short distance measurement value of object parameters to the remote measuring station to realize the long distance measurement. Telemetry is a comprehensive technology using sensing technology, communication technology and data processing technology. Telemetry is mainly used for centralized detection of scattered or inaccessible tested objects, such as remote distance, harsh environment, or high-speed motion. Telemetry is widely used in national economy, scientific research, military technology and so on. Using telemetry can realize centralized monitoring, improve automation level, improve labor productivity, improve working conditions and improve scheduling quality. Telemetry provides an important testing method for scientific research, which makes it difficult to carry out actual measurement research projects and obtain important dynamic performance data.

 

Remote control
The technology of controlling long-distance controlled objects through communication media. It consists of operating device, coding device, transmitting device, channel, receiving device, decoding device, executing mechanism, etc. According to the channel medium, it is divided into wired remote control, wireless remote control and optical remote control; According to the transmission mode of the control signal, it is divided into single channel remote control and multi-channel remote control, etc. Controlled objects are divided into medium-sized (such as factories, power stations, etc.) and decentralized (such as transmission lines, etc.) according to their distribution locations.

Current situation and prospect
Although the remote control and telemetry industry has occupied a large number of markets in economic, military, scientific research and other fields, there are still many markets waiting for it to develop. The implementation of the Western Development Strategy provides a huge new market for the remote control and telemetry industry. Many areas in the West are vast and sparsely populated, and their working and living environments are extremely harsh, which brings many difficulties to economic development. Using remote control and telemetry technology can improve people's working conditions, reduce field work, and monitor and control equipment which is far apart and scattered in harsh environment in a comfortable room with air conditioning. There are abundant water resources, oil and gas resources in the West. In the development of these energy resources, the establishment of unattended hydrological observation system, various water conservancy facilities, the monitoring and management of hydropower facilities and power network operating conditions and the monitoring of oil and gas pipelines are all markets to be occupied by the remote control and telemetry industry. Monitoring of environmental pollution in environmental protection, monitoring and management of high-grade highways in traffic facilities construction, monitoring and management of various pipe networks such as water, electricity, gas and heat in newly built towns, automatic monitoring of production lines in newly-built factories and mines and so on are all broad markets of remote control and telemetry industry.
With the vigorous development of urban public utilities, it is required to strengthen the development of sensors, increase their types, improve their accuracy and quality, and improve the reliability and accuracy of monitoring systems, in order to improve the security of the monitored pipe network and the scientificity of resource scheduling management; It is required to network the monitoring system of the urban public utility network, establish a regional office network, and uniformly schedule the resources of the monitored pipe network, reasonable utilization. These demands to improve the monitoring level of urban public utilities network have opened another market for remote control and telemetry industry.
