[0040] In the embodiment, when the user pushes the sealing cover 5 upward, the rotating arm 6 rotates clockwise with the sealing cover 5, and drives the rotating shaft 9 and the torsional spring 10, at this time, the torsional spring 10 is tightened due to the force, when the external reading equipment is connected into the analog input port 2, the cable of the equipment provides support for the sealing cover 5, so that the torsional spring 10 can continue to be tightened, when the external reading equipment is taken out from the analog input port 2, the sealing cover 5 loses the support, so that the torsional spring 10 can release the pressure to drive the rotating shaft 9 and the rotating arm 6 to rotate counterclockwise, so as to make the sealing cover 5 cover the plug-in port 13 again.

[0045] In combination with Embodiment One and Embodiment Two, the working principle of the multi-channel analog input / output assembly is as follows:

[0046] First, when it is needed to connect an external device to the multi-channel analog input / output assembly, the user can first find the corresponding analog input port 2. At this time, the wire insertion port 13 of the analog input port 2 is covered by the sealing cover 5 to prevent dust from entering. The user can press the pressing plate 4 to make the other end of the sealing cover 5 be raised upward by using the lever principle, and then dislodge the sealing cover 5 from the wire insertion port 13.

[0047] With the dislodging of the sealing cover 5, the limiting block 11 is disengaged from the docking opening 12, and the torsional spring 10 is in a compressed state. Then, the connecting head of the external device is inserted into the interface 15 of the analog input port 2. After the connection is completed, the cable of the device connecting head provides certain support to the sealing cover 5, so that the torsional spring 10 remains in a tightened state. When the device connecting head is pulled out, the torsional spring 10 releases energy immediately, drives the rotating arm 6 to rotate counterclockwise through the rotating shaft 9, and finally makes the sealing cover 5 cover the wire insertion port 13 again. The limiting block 11 and the docking opening 12 are embedded, thereby achieving a good sealing effect.

[0048] In the case where multiple analog input ports 2 work simultaneously, each port can independently receive analog signals such as current or voltage signals from different devices. These signals are then converted into digital signals through AD conversion and related chip processing, and are transmitted to the control system through the bus communication port 3. The control system processes and controls according to the received digital signals, thereby realizing the parallel work of multiple devices and the efficient transmission of data.

[0049] In addition, the multi-channel analog input / output assembly also has high reliability and durability. The rubber inner ring 14 outside the interface 15 not only improves the tightness between the connecting head and the interface, but also can resist vibration and impact to a certain extent, ensuring the stability and safety of the connection. At the same time, the sealing cover 5 and the flip assembly can maintain the sealing and cleanliness of the port.
