The invention discloses a system for achieving wireless target floor group-control selection through mobile terminal devices. The system comprises a lift control system, a lift wireless terminal receiving and transmitting host, a plurality of mobile wireless terminal receiving and transmitting devices, wherein the lift control system, the lift wireless terminal receiving and transmitting host and the mobile wireless terminal receiving and transmitting devices are connected in sequence. The lift wireless terminal receiving and transmitting host comprises a CAN communication module, a first microprocessor and a first wireless module, wherein the CAN communication module, the first microprocessor and the first wireless module are connected in sequence. Each mobile wireless terminal receiving and transmitting device comprises a second microprocessor, a second wireless module, an oscillator, a touch screen and a display device, wherein the second microprocessor is connected with the second wireless module, the oscillator, the touch screen and the display device. According to the system for achieving wireless target floor group-control selection through the mobile terminal devices, the wireless technology is combined with a lift, passengers achieve target floor selection through a human-machine interface in the manner that mobile wireless terminals are connected with the wireless terminal on the floor where a lift is located, the target floor selection efficiency can be effectively improved, and the situation that the passengers line up to select target floors when the passenger flow is large is avoided; and in this way, the efficiency of the lift is improved, and the overall lift taking time is shortened for the passengers.
