Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

Currently, when the sensor is mounted to the display, a plurality of separate sensor circuit boards of different types are typically connected to the main board of the complete machine. In this way, based on the fact that the number of the sensor circuit boards is large, insufficient interfaces of the whole machine main board can occur during wiring, wire pressing is required, and wire processing requirements, cost and reject ratio are all increased. In addition, because the communication interfaces of the sensors of different types are inconsistent, different adapting ports are needed for the whole machine main board, and the cost investment is high. The data acquired by the sensing element in the sensor circuit board is read through the whole machine main board, the read data cannot be directly used, the whole machine main board is required to process the data, and the operation load of the whole machine main board is increased; and data errors and leaks are likely to occur when item migration is performed. When a new sensor circuit board needs to be added, the driving code of the whole main board needs to be correspondingly modified, and the labor cost investment is high.

Currently, when the sensor is arranged on the display, a plurality of sensors can be integrated into a sensor box, and then the sensor box is connected with a main board of the whole machine. In actual use, the use of the same sensor box may result in redundant functions based on different requirements of different items, resulting in wasted resources. In addition, when the sensor type needs to be added to the sensor box, the hardware, the software and the structure of the sensor box need to be greatly changed, and thus high labor cost is required.
