Embodiment 1
[0034] Such as figure 1 As shown in FIG. 1 , it is a schematic flowchart of realizing that each wireless transmitting terminal has a different working frequency from other wireless transmitting terminals through frequency hopping in Embodiment 1 of the present invention. Before performing frequency hopping, it is first necessary to power on all wireless transmitters, and set a power-on time difference between the wireless transmitters, that is, the wireless transmitters are powered on in a corresponding order. The minimum allowable difference in power-on time is 1 ms.
[0035] In addition, each wireless transmitter also presets an initial operating frequency f0, so that after all wireless transmitters are turned on, each wireless transmitter will work at the initial operating frequency f0, which is equivalent to completing the initialization of the wireless transmitter. process.
[0036] After the wireless transmitter completes the initialization, it starts a process of freq...
Embodiment 2
[0047] Such as figure 2 As shown, it is a schematic flow diagram of realizing that each wireless sending end has a communication address different from other wireless sending ends by adding a communication address in the wireless data signal in Embodiment 2 of the present invention. The specific flow is as follows:
[0048] First of all, write a unique communication address in all wireless transmitters and wireless receivers. Specifically, by adding a communication address in the communication protocol between wireless transmitters and wireless receivers, all wireless transmitters The wireless receiving end and the wireless receiving end have their own different communication addresses, and the communication between the wireless sending end and the wireless receiving end is unique;
[0049] Secondly, when each wireless transmitting terminal sends a wireless data signal to the wireless receiving terminal, the communication address of the destination wireless receiving terminal...
