In view of the problem that the number of remote controllers increases synchronously with the number of receivers in ordinary one-to-one wireless remote control systems, the remote controllers are inconvenient to keep and easy to confuse, a solution of N-in-one wireless remote control system is proposed. The practical circuit of N-in-one remote controller is given. There are usually two methods to realize N-in-one remote control and make a remote controller have the function of selecting one address from N addresses: one is the direct selection method and the other is the cyclic selection method. The four-in-one remote control system designed and manufactured based on the multi-address cyclic selection method has been successfully used for the remote control adjustment of four digital display boards in the Daqing Oilfield Power Dispatching Center in May 2009. The N-in-one wireless remote control system is particularly suitable for occasions where there are multiple receivers in the same application space and each receiver can execute multiple remote control commands.
