The following detailed description, in conjunction with specific accompanying drawings, illustrates the invention.
[0030] refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the thermal control instrument provided in the embodiments of this application; Figure 2 An electrical block diagram of a thermal control instrument provided in an embodiment of this application.
[0031] exist Figure 1 and Figure 2 This application provides a thermal control instrument, including: an instrument housing 1, wherein,
[0032] The instrument housing is provided with a first chamber, a second chamber, and a third chamber.

[0036] The sensor interface is used to connect external sensors;
[0037] An output interface 5 is installed on the side wall of the third chamber.
[0038] The output interface is used to output control signals.
[0039] In the above technical solution, by setting up an instrument housing, the instrument housing is provided with a first chamber, a second chamber, and a third chamber. The first chamber is provided with a control module, and a display screen and a communication module are provided on the side wall of the first chamber. The display screen is used to display thermal parameters and operation menus. A sensor interface is installed on the side wall of the second chamber for connecting external sensors. An output interface is installed on the side wall of the third chamber for outputting control signals. This improves the control accuracy and response speed of the thermal power plant production process.
[0040] Specifically, the beneficial effects include:
[0041] 1. Improve control precision
[0042] This thermal control instrument rationally partitions the control module, sensor interface, and output interface by independently setting up a first, second, and third chamber. This partitioned design effectively reduces electromagnetic interference between different functional modules, ensuring that the control module can more accurately receive data from the sensors and accurately calculate and output control signals according to preset algorithms, thereby significantly improving the control accuracy of thermal parameters such as temperature, pressure, and flow rate during the production process of thermal power plants.
[0043] The display screen can show thermal parameters and operation menus in real time and accurately. Operators can make more precise parameter adjustments and equipment control based on this accurate data, which further improves the control accuracy of the entire system.
[0044] 2. Enhanced response speed
[0045] The sensor interface is directly mounted on the side wall of the second chamber, which shortens the signal transmission path between the sensor and the control module, reduces the delay in the signal transmission process, and enables the control module to obtain the thermal parameter change information collected by the external sensor more quickly.
[0046] After receiving the sensor signal, the control module can quickly process it and generate the corresponding control signal, which is then output in a timely manner through the output interface on the side wall of the third chamber. This enables rapid control of the actuator, thereby effectively improving the response speed of the thermal power plant's production process, better adapting to dynamic changes in the production process, and ensuring the stable operation of the production process.
[0047] 3. Easy to maintain and manage
[0048] The compartmentalized design allows each functional module inside the instrument to operate relatively independently. When a module in a particular compartment malfunctions, maintenance personnel can more easily locate and repair it without having to disassemble the entire instrument on a large scale, which greatly shortens maintenance time and reduces maintenance costs.
[0049] The communication module facilitates data interaction between the instrument and the host computer or other control systems. Operators can obtain the instrument's operating status and thermal parameters in real time through the remote monitoring and management platform, enabling remote configuration, parameter adjustment, and fault diagnosis of the instrument, thereby improving the management efficiency and maintenance convenience of the instrument.
[0050] 4. Improve system reliability
[0051] The rational chamber layout and modular design improve the instrument's anti-interference ability and stability, reduce the probability of instrument failure caused by external environmental factors or internal electromagnetic interference, ensure the reliability of thermal parameter control during the production process of thermal power plants, reduce the risk of production accidents caused by instrument failure, and ensure the safety and continuity of production.
