It consists of a program counter, an instruction register, an instruction decoder, a timing generator and an operation controller. When raising livestock and poultry, the environment needs to be controlled, so an environmental controller is used. Therefore, a shell is used to perform positioning and protection operations on the controller.

[0003] The prior art application number is 202120888272.5, which discloses a waterproof controller housing for a refrigeration environment, including a front shell and a rear shell that are detachably connected to each other, the front shell is in a "T" shape as a whole, and is mainly composed of a front panel and a rear groove cavity, and water retaining ribs are formed around the front panel at the connection between the two, and a guide groove I is provided above the rear groove cavity at the connection between the two; the rear shell is in an inverted "U" shape as a whole, and is installed at the free end of the rear groove cavity of the front shell, forming a seam with the front shell on the side, and a circle of guide grooves II is provided on the side of the rear shell, and the assembled guide groove is located in the rear groove cavity. The utility model has excellent waterproof performance, can prevent water from penetrating into the circuit board in all directions, can extend the service life of the product, reduce the risk of short circuit of the product due to use in a humid environment, and greatly enhance the safety of terminal equipment and personnel.

[0004] The waterproof controller housing for a refrigeration environment proposed in the above application has excellent waterproof performance during use, which can prevent water from seeping into the circuit board and extend the service life. However, when it needs to be disassembled for inspection and repair, it is inconvenient to disassemble and assemble it, which is inconvenient for subsequent repair and maintenance operations by staff, affecting the normal use of the housing.
