Problems solved by technology

[0003] However, the above-mentioned detection scheme has the following technical defects: 1. A special signal generator is required to provide detection signals, and the cost is relatively high; 2. If there are antennas with multiple frequency bands, multiple signal generators need to be configured, which will not only greatly Increase the cost, and multiple signal generators are likely to cause cross-intermodulat

Abstract

The invention discloses an antenna connection detection method. The method comprises the following steps: transmitting a signal through a transmitting antenna of a wireless module; scanning the intensity of sideband noise and/or harmonic signals received by a receiving antenna of the wireless module; the sideband noise and the harmonic signal are generated by a signal transmitted by the transmitting antenna; and analyzing the strength of the sideband noise and/or harmonic signal received by the receiving antenna to obtain the connection state of the transmitting antenna and the receiving antenna. According to the method, the sideband noise generated by the signal transmitted by the wireless module and the harmonic signal replace an external signal generator to serve as an information source, so that the detection cost can be reduced, and the detection accuracy can be improved. The invention further discloses an antenna connection detection device and equipment and a computer readable storage medium which all have the above technical effects.

Description

technical field [0001] The present application relates to the field of wireless communication technologies, and in particular, to an antenna connection detection method; and also to an antenna connection detection apparatus, device, and computer-readable storage medium. Background technique [0002] Mobile communication has entered the era of 4G and 5G, and the frequency bands of wireless products are more and more complex, which makes the wireless system of wireless products more modularized into wireless modules. The wireless module needs to complete various tests and verifications before leaving the factory to ensure that the conduction index meets the requirements. During the production test of the wireless module, it is necessary to detect the connectivity of the antenna to determine whether the wireless system assembly is normal. refer to figure 1 As shown, the current method of detecting the wireless module is roughly as follows: prepare the signal generator and con...
