Problems solved by technology
[0003] At present, the communication performance of the computer is one of the important performances of the computer, so it is necessary to detect the strength of the computer communication signal. However, due to the different installation positions of the signal receiving devices, it is difficult to obtain the accurate signal emitted by the computer to be tested, and it is impossible to perform performance tests on computers operating under high temperature conditions.

The invention discloses a communication performance test system which comprises an electromagnetic shielding chamber, a wave absorbing material, an annular track, a platform to be tested, a receivingplatform, a signal receiving device, a humidifying device, a humidity sensor, a central processing device, a frequency spectrum tester, a signal analyzer, a display device, an image acquisition moduleand an image processing module. According to the communication performance test system, the signal receiving device collects signals transmitted by the computer to be tested at different positions inthe electromagnetic shielding chamber; Meanwhile, a humidity sensor and a humidifying device are used for controlling the humidity in the electromagnetic shielding chamber, and the humidity in the electromagnetic shielding chamber can be set according to the requirements of experimenters so as to test the highest humidity of the computer to be tested, which can operate normally.
Description
technical field [0001] The invention relates to the technical field of computer testing, in particular to a communication performance testing system. Background technique [0002] Computer communication network is a new communication method formed by the combination of computer technology and communication technology, mainly to meet the needs of data transmission. It is a communication system formed by connecting multiple computer terminals and ancillary hardware devices (routers, switches) with different geographical locations and independent functions with communication links, and equipped with corresponding network software to realize resource sharing in the communication process. It can not only meet the data and file transmission needs of an enterprise, company, school and office in a local area, but also can exchange, store and process information in a country or even the whole world, and can provide integrated voice, data and image Sexual services are the only way fo...
