rtu-besturingssysteem
The rtu control system is referred to as rtu, and the Chinese name is: remote telemetry terminal. It is a device that mainly integrates remote control and data transmission. It usually has DI (switch input), DO (switch output), AI (analog input), AO (analog output) interface, which can remotely control the switch. Control current output, etc.
This type of product also has many network types, such as 4G, LoRa, Ethernet, NB-iot, GPRS, etc. However, as of 2021, GPRS has gradually faded out of our field of vision, and currently it is mainly based on 4G rtu-besturingssysteem .
The RTU control system products developed by Zongheng Intelligent Control have: (1) The realization of safety, reliability and stability, especially reliable and stable operation, protection, collection, control, display and other functional programs Software; (2) Achieve good communication between system devices; (3) Effectively realize various functions of RTU.
It also has the following key technologies:
1. Wireless testing technology for displacement, load and pressure: using high-precision, zero-drift load, displacement sensors and micro-mechanical wireless electronic technology, with compact structure, light weight, easy installation, able to adapt to harsh working environments in the field, and measurement accuracy errors ≤1%;
2. Low energy consumption technology: Using the latest low energy consumption main control chip and corresponding energy-saving control program and lithium-ion battery, the power consumption of the instrument during normal operation is μA level. Without external power supply, it can work normally for more than 2a. Achieve zero maintenance work goals.
3. Data wireless transmission technology: RTU has built-in GPRS wireless data transmission module and digital signal transmission technology, which can realize remote monitoring of all data of a single well such as power diagram, pressure, flow, temperature, etc. and the start, stop and speed regulation of oil wells through wireless means. Control and data transmission are fast, accurate and reliable, especially suitable for mountainous areas, hills, swamps, lakes, deserts and other environments.
Main functions of rtu control system
(1) Data collection: collect pressure, flow, displacement, load, stroke, etc.;
(2) Data transmission: The collected data is transmitted wirelessly;
(3) Data monitoring: The host computer monitors data and controls the actions of the equipment;
