A wireless gateway scheme with multiple frequencies working in parallel

Most wireless chips on the market can only work on one frequency at a time. If a single wireless device needs to receive multiple frequency signals, the device can only be controlled to continuously switch frequencies and detect signals on each working frequency band. This method is not only time-consuming and complicated, but also because the device cannot receive signals of the other frequency when the device is in one of the frequencies, it is easy to cause data loss.

The multi-channel parallel gateway uses the way of paralleling multiple wireless devices to realize fast, switch-free, and stable communication multi-frequency wireless reception.

The parallel gateway includes a receiving part and a transmitting part.

The structure of the receiving part is to connect multiple wireless receiving modules with different frequencies in parallel, and collect the received wireless data through a multi-level single-chip microcomputer, and use the serial port TXD to output to the external device to realize multiple wireless parallel reception.

The implementation is as follows:

1.According to the required frequency channel N, prepare N wireless receiving modules, and place each module in channel 1, channel 2...channel N in turn.

2.Connect the output terminals of the two wireless modules to a single-chip microcomputer in turn to form the first-level output.

3.The two outputs of the first-level single-chip microcomputer are connected to a second-level single-chip microcomputer in turn.

4.When the single-chip microcomputer collects the complete data of any channel of the previous level, it is output to the next-level MCU.

5.Repeat the two outputs of the previous stage to the next stage until the final output is 1.
