Abstract
Description
Technical Field
[0001] This utility model relates to the field of control unit technology, specifically to a main control unit structure. Background Technology
[0002] With the development of industrial automation, power monitoring and other fields, the requirements for control units are becoming increasingly demanding. Existing control units have certain limitations in terms of functional integration, signal processing accuracy, and network communication stability, making it difficult to meet the diverse needs of complex industrial environments.
[0003] Currently, common control units typically consist of multiple functional modules, such as a main control board, communication board, temperature acquisition board, and power control board. However, the integration between these modules is low, resulting in a large control unit size and inconvenient installation and maintenance. For example, the connection between the main control board and the temperature acquisition board, power control board, etc., often requires a large number of cables, which not only increases the complexity of the system but also easily introduces electromagnetic interference, affecting the accurate transmission of signals.
[0004] Therefore, a main control unit structure is proposed. Utility Model Content
[0005] The purpose of this utility model is to provide a main control unit structure in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0007] A main control unit structure includes a base box and an upper box, which are plugged into each other. Wiring conduits are provided on both side walls of the base box, and current acquisition sensors are fitted onto the surface of the conduits. A main control unit module assembly is housed inside the base box and the upper box. The main control unit module assembly has two sets of controller signal wiring ports, used for inputting and outputting control signals, respectively. The main control unit module assembly also includes a bus internet port, a controller station number display, and a controller station number selection button.
[0008] Furthermore, the main control unit module includes a power board and a current acquisition board vertically inserted into the bottom box, and a temperature acquisition board is connected to the power board and the current acquisition board. Two sets of controller signal wiring ports are fixedly installed on the temperature acquisition board. A communication control board is fixedly connected to the temperature acquisition board, and a controller main control board is fixedly connected to the communication control board. The bus internet port, controller station number display, and controller station number selection button are located on the controller main control board and are plugged into the top surface of the bottom box. The wiring conduit is connected to the power board and the current acquisition board.
[0009] Furthermore, multiple sets of heat dissipation holes are provided on both sides of the bottom box, and mounting protrusions are installed on both sides of the bottom box, with mounting holes provided on the mounting protrusions.
[0010] Furthermore, the bottom surface of the base box has a mounting groove, and a guide rail mounting buckle is provided in the mounting groove.
[0011] Furthermore, two sets of controller terminal covers are hinged to the top surface of the upper box, and the two sets of controller terminal covers are respectively set to correspond to the two sets of controller signal wiring ports.
[0012] Furthermore, the inner wall of the bottom box is provided with a buckle protrusion, and the surface of the upper box is provided with a buckle groove. When the bottom box and the upper box are closed, the buckle protrusion and the buckle groove are engaged.
[0013] The beneficial effects of this utility model are as follows:
[0014] By plugging the bottom box and the top box together, and integrating the main control unit module components inside, a modular design is achieved. This not only makes the control unit smaller and easier to install in a small space, but also greatly simplifies the maintenance process.
[0015] By integrating a power board, current acquisition board, temperature acquisition board, communication control board, and controller main control board, and through two sets of controller signal wiring ports, bus Internet port, controller station number display, and controller station number selection button, the system realizes signal input, output, and network communication functions. The highly integrated design reduces the cable connections between modules, reduces the complexity of the system and the risk of electromagnetic interference, and improves the stability of signal transmission.
[0016] By installing a current acquisition sensor on the surface of the conduit, real-time current data can be collected from the power conductors passing through the conduit. This enables the control unit to accurately monitor the operating status of the power system, detect abnormal currents in a timely manner, and provide strong protection for the safe operation of the system.
