1. In the choice of the switch, the switch with multiple transmit and receive antennas is selected, which reduces the drop rate, that is, MIMO technology. This technology combines with OFDM and space-time coding technology to realize spatial diversity and frequency diversity. Time diversity. Realize anti-interference in airspace, frequency domain and time domain. At the same time, the channel capacity provided by MIMO is large, which provides a large range of variation for data and anti-interference in the speed domain. 2. Channel selection, in the case of a large number of production lines, in order to prevent communication failures, select different channels for them, avoiding the repetition of the channel. 3. Add a power amplifier to the AP main station to increase the power of the transmitted signal. 4. Place the AP master station in the middle of the track to increase the communication distance between the AP master station and the two tractors. 5. If it still doesn't work, you need to change the communication method. The wireless communication method can meet most industrial environments, but occasionally, there will be occasional dropped calls, such as the equipment we debugged in Qingyuan. v The industrial environment of the equipment is relatively complicated. There is a large substation outside the workshop. The electromagnetic signal is very complicated and the mobile phone signal is weak. In the production line of this workshop, we have adopted the above measures, although improvements have been made. However, there will still be occasional dropouts, which is not allowed in industrial situations where stability is high. Finally, we have to change the communication method, using optical communication, adding at both ends of the track. The glazing communication module adds an optical communication module to the two tractors, and the optical communication module at both ends of the track and the controller take the DP communication mode, thus completely solving the problem of electromagnetic interference.
