Concrete, described wireless signal transmitter comprises load module, the processing module that transmits and transmitter module, and described signal processing module is connected with transmitter module with load module respectively.
Concrete, described load module is one or more in keyboard, touch-screen and voice input device.
The control mode that adopts multiple control modes to combine in this programme, the control module that also can adopt rocker lever to be combined with button, its advantage is to make operator to simulate the mode of operation in cab, directly by the rocking bar control tower machine arranging on handle, similar with the control rocking bar in cab, make operator can adapt to faster remote control and control.
Concrete, described in the processing module that transmits comprise coding unit, carrier modulation unit and the signal amplification unit connecting successively.
Concrete, described transmitter module is emitting antenna.
Concrete, described wireless signal receiver comprises reception signal processing module and output circuit, described output circuit is connected with driver module with reception signal processing module respectively.
Concrete, described reception signal processing module comprises signal amplification unit, demodulating unit, decoding unit and the driver element connecting successively.
Concrete, also comprising electric protection module and detent, described electric protection module is connected with driving circuit, and described detent is connected with transmission module respectively at driving circuit.
The object that electric protection module is set is; when tower machine possesses manual control and wireless remote control control simultaneously; can only allow at one time a kind of control mode to control tower machine, avoid meeting accident, therefore need electric protection module to carry out electric lock operation.
Concrete, described electric protection module is switch.
The advantage that switch is set is, installs after inside and outside switch, and inside and outside control circuit board philosophy is controlled manually and remote control, and when switch is during at interior location, the work of internal control circuit plate, can only realize manual operation; When switch is externally during position, the work of external control circuit plate, can only realize straighforward operation; And by controller, circuit is carried out to electrical interlocks, guarantee the safe operation of crane.
Concrete, described wireless signal transmitter is provided with limit switch, starts module and alarm module.
The beneficial effects of the utility model are, have improved work efficiency, and operating personnel can independent judgment, thereby accuracy, the continuity of operation were significantly improved than in the past; Also save commander's link, thereby avoided the improper misunderstanding causing due to commander; Operator can be in commander's angle operation, see clearly more intuitively by article hoisting field condition, avoid in addition tower crane operation person insecurity in pilothouse under inclement weather, and operator's work high above the ground and commander link up wrong and cause unnecessary accident, in remote control situation, also can realize a people and control many tower machines.
Accompanying drawing explanation
Fig. 1 is the theory diagram of wireless remote controller of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, describe the technical solution of the utility model in detail:
As shown in Figure 1, wireless remote controller for tower crane described in the utility model, comprise wireless signal transmitter, wireless signal receiver, driver module, delay control circuit and transmission module, described wireless signal transmitter matches and is connected by wireless signal with wireless signal receiver, and described driver module is connected with wireless signal receiver, transmission module and delay control circuit respectively.Operator can realize the repertoire by manual drive tower machine operation person hands-operation by straighforward operation, can complete simultaneously tower machine forward, backward, upwards, downwards, left, to the right, location and gearshift; Be specially: according to the actual needs of tower machine work, corresponding button in push key circuit, produce thus one group of binary data code, under the control of the processing module that transmits, a string data code is sent to modulator circuit from cell encoder, digital signal is converted to the simulating signal of transmitting on carrier current channel in modulator circuit.This simulating signal enters radiating circuit via interface circuit, and goes out by transmission antennas transmit.Signal receiving processing module is received after the next carrier signal of Digiplex transmitting, via receiving circuit and interface circuit, is entered demodulator circuit.Demodulation is contrary with modulation, recovers data code from carrier wave.Data code after demodulation is sent into decoder circuit, demoder is delivered to decoder circuit by understanding correct code signal, after decoder for decoding, by driver module, drive corresponding relay to work, thereby control tower machine transmission module carries out transmission, just completed thus button remote control tower machine and carried out work.
