[0038] The present application will be further described in detail below with reference to the accompanying drawings.

[0039] Reference Figure 1 and Figure 2 This application discloses an RTU controller, including a housing 1, a processing module 2, and a circuit board 3.

[0040] The housing 1 has a mounting cavity 11. The mounting cavity 11 includes a mounting groove 111 and a plurality of mounting areas 112. The plurality of mounting areas 112 surround the mounting groove 111.

[0041] The processing module 2 is installed in the mounting slot 111. Multiple circuit boards 3 are provided, each corresponding to a mounting area 112. The circuit boards 3 are installed in the mounting area 112 such that multiple circuit boards 3 surround the processing module 2.

[0042] The RTU controller also includes a data cable 4. A port is provided on the circuit board 3. One end of the data cable 4 is connected to the port, and the other end of the data cable 4 is connected to the processing module 2 to enable data transmission between the circuit board 3 and the processing module 2.

[0043] In one embodiment: the data cable 4 is flexible. The circuit board 3 is first installed in the mounting area 112, with the port of the circuit board 3 facing the opening of the mounting cavity 11, and then the data cable 4 is connected.

[0044] In the embodiments of this application: Refer to Figure 2 and Figure 3 The data cable 4 is fixedly connected to the housing 1. One end of the data cable 4 corresponds to the mounting area 112, and the other end of the data cable 4 corresponds to the mounting groove 111. For example, the data cable 4 is embedded in the material of the housing 1, and the end of the data cable 4 extends out to form a contact. The port of the circuit board 3 is away from the opening of the mounting cavity 11, and the circuit board 3 is installed in the mounting area 112. Then the port of the circuit board 3 is connected to one end of the data cable 4.

[0045] To ensure that circuit board 3 is installed correctly so that its port is connected to data cable 4.

[0046] When circuit board 3 is axially symmetric or centrally symmetric, circuit board 3 is provided with a foolproof notch. For example, fan-shaped, arc-shaped, regular pentagon, isosceles trapezoid, and isosceles triangle are axially symmetric; parallelogram, circle, and regular hexagon are centrally symmetric.

[0047] Circuit board 3 can also be a non-axisymmetric or non-centrally symmetric shape. For example, a trapezoid (excluding isosceles trapezoids), a triangle (excluding isosceles triangles), and circuit board 3 (A) in the attached diagram.

[0048] Preferably, the circuit board 3 has two adjacent sides that are not perpendicular, so that the circuit board 3 is a non-axisymmetric and non-central symmetric shape, thereby improving its recognizability.

[0049] The implementation principle of an RTU controller in this application embodiment is as follows: modular installation is achieved, and if a circuit of a certain function is damaged, only the corresponding circuit board 3 needs to be disassembled and reassembled to complete the repair.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
