When testing the transmission performance of the mobile terminal, the signal transmitted by the mobile terminal 102 to be tested is received by the antenna 103. Since the radiation intensity around the mobile terminal 102 to be tested is not uniform, the radiation intensity in some parts is high, and the radiation intensity in some parts is small , therefore, when the performance of the mobile terminal to be tested is normal, if the radiation intensity of this antenna is low, there will be a problem of false detection, and the mobile terminal with normal performance will be falsely detected as a defective product, thereby reducing the productivity
Equally, when testing the receiving performance of the mobile terminal, the signal transmitted by the antenna 103 is received by the mobile terminal 102 to be tested. Since the signal strength around the antenna 103 is not uniform, some parts have a large radiation intensity, and some parts have a small radiation intensity. Therefore, when the performance of the mobile terminal to be tested is normal, if the location of the mobile terminal to be tested is a position with a low radiation intensity of the antenna, the problem of false detection will occur, and the mobile terminal with normal performance will be falsely detected. into defective products, thereby reducing production efficiency

The invention discloses a signal detection device and a method and system for detecting the receiving and transmitting performance of a mobile terminal. According to the specific execution mode, the signal detection device comprises a shielding box, at least two test antennas, at least one device used for equally distributing and transmitting one path of input signals to all the test antennas and at least one device used for combining the signals received by all the antennas into one path of signals and outputting the signals, wherein the shielding box is used for containing a mobile terminal to be detected and the test antennas, and the test antennas are used for transmitting or receiving the signals and are arranged in the shielding box respectively. By the adoption of the signal detection device, a more accurate test result can be obtained on the condition of not changing the number of input or output interfaces, and the problem that a mobile terminal with normal performance is mistakenly tested as a bad product is avoided, so that the production efficiency is improved.
