The frequency channel may be a frequency or a frequency band. Preferably, the signal transmitting module is configured to transmit wireless signals of a plurality of frequency channels. According to the preferred embodiment, one signal transmitting module can transmit signals to a plurality of signal receiving modules, so that one transmitting device can control a plurality of receiving devices (namely a plurality of engineering machines). In this embodiment, the signal receiving module on each construction machine receives one of the wireless signals of the plurality of channels, and the channels of the wireless signals received by the signal receiving modules on different construction machines are different, and when the channel set by the signal transmitting module, i.e., the transmitting device, is the same as the channel set by the signal receiving module, i.e., the receiving device, the transmitting device can control the receiving device, so that when a plurality of construction machines are simultaneously operating, each construction machine can be accurately controlled, and communication and control confusion can be prevented.
