Abstract:
1. A transmission method of the one-to-many 2.4G wireless computer peripheral communication device comprising a 2.4G wireless USB transmit-receive adapter connected with a USB interface of an intelligent appliance, and more than one 2.4G wireless computer peripheral cooperated with the USB transmit-receive adapter, comprising the following steps: (1) Presetting an occupied time period of each 2.4G wireless computer peripheral: pre-sort the 2.4G wireless computer peripherals and allocate an occupied time period for each of the 2.4G wireless computer peripherals according to the types thereof, take the sum of all the periods of occupied time period allocated to each peripheral as a preset cycle time, and then store corresponding information into the 2.4G wireless USB transmit-receive adapter and each 2.4G wireless computer peripheral; (2) Selecting a channel: after the 2.4G wireless USB transmit-receive adapter starting up, the 2.4G wireless USB transmit-receive adapter will send out testing packets of different channels circularly, pick out a channel with better communication quality according to the success rate of receiving testing packets thereof, and then carry out a calculation so as to determine a frequency hopping sequence; (3) Establishing a channel: based on the selected channel and pre-sorting of each peripheral, the 2.4G wireless USB transmit-receive adapter will send out different corresponding paging instructions at a periodic interval of preset cycle time; when the 2.4G wireless computer peripherals starting up, the 2.4G wireless computer peripherals will return a reply instruction after receiving a paging instruction; after receiving the reply instruction from a certain 2.4G wireless computer peripheral, the 2.4G wireless USB transmit-receive adapter will send a corresponding data information instruction to this 2.4G wireless computer peripheral during next cycle time, otherwise will continue to send out this paging instruction until build a communication channel with this 2.4G wireless computer peripheral; and (4) Transmitting data: after a certain 2.4G wireless computer peripheral receiving a data information instruction transmitted thereto, this 2.4G wireless computer peripheral will return a reply instruction or a reply instruction with data information during the occupied time period pre-allocated thereto, and then will be in standby mode before next cycle coming; after receiving the reply instruction from a certain 2.4G wireless computer peripheral, the 2.4G wireless USB transmit-receive adapter will send a next section of data information instructions to this 2.4G wireless computer peripheral during next cycle time, otherwise will continue to send out original data information instructions.
