Therefore, based on the great increase of the demand of the 5G communication module, the existing 5G communication module detection device has poor compatibility, low detection efficiency and complex operation, and cannot meet the requirement of mass production detection.
In the prior art, PC is used as a core to develop upper computer test software, test records and test results are stored in a local file. The test base plate and the 5G tested module adopt different forms of interfaces for communication (USB, RS232 interface, RS485, CAN interface and the like are arranged), and most of the test base plates are only suitable for customized 5G communication module test, and the prior art scheme is shown in figure 1.
The whole testing flow of the detection device is that the PC end is communicated with the testing bottom plate (USB, ethernet and the like are adopted), the PC end is a main control center, and the PC end is mainly responsible for reading the configuration file of the detection scheme, controlling the detection flow, and locally storing the detection result and the detection record. The test base board is responsible for executing the test items and the test flows scheduled by the PC side. Detection of the 5G communication module is completed through frequent interaction of detection information between the test board and the PC end, but the prior art scheme has the following defects:
1. In the prior art, the test function is basically bound with hardware, if a detection item is newly added, the test function is correlated with the hardware, the function expansion of the test base plate is inflexible, the aim of upgrading the function of the whole system can not be achieved by upgrading the adaptive test software, and the later maintenance workload is large;
2. the PC terminal modifies the configuration file and modifies the detection scheme to have complex operation, large maintenance workload and relatively low efficiency; the detection result and the detection record are stored locally at the PC end, and centralized management is not performed;
3. A detection device needs to be provided with a computer and a display, and has high cost and poor portability;
4. Different interfaces of the 5G communication modules are different (generally, a USB port form, a CAN bus form, an RS485 interface form, an RS232 interface form and the like) and are difficult to be compatible with each other, and the flexibility is poor, so that the detection cost is high.
The information disclosed in this background section is only for enhancement of understanding of the general background of the utility model and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art.
