Technical field
The utility model relates to a kind of industrial radio remote controller.
Background technology
Industrial radio remote controller is used for the operation of remote control commercial unit, usually form by transmitter and receiver, its transmitter and receiver of current industrial radio remote controller still adopts the single-simplex operation pattern, and the employing of the base band of the base band of transmitter and receiver all is monokaryon (microprocessors).Finish the scanning of pushbutton switch by the microprocessor in the transmitter base band, form the serial command sign indicating number, chnnel coding is carried out in instruction, form the data stream of emission; Radiofrequency signal enters the receiving cable of receiver, sends into the baseband circuit of receiver again and handles, and result is carried out by instruction execution unit, finishes the control to equipment.This telepilot is because transmitter and receiver adopts the single-simplex operation pattern, when there is interference in receiver, transmitter can not disturb differentiation, when having co-channel interference on the working channel, can not eliminate and disturb or withdraw from interference channel, therefore the major defect of this telepilot is that interference free performance is poor, especially anti-co-channel interference poor performance.Along with various commercial units become increasingly complex, control accuracy requires more and more higher, and uses the situation of several telepilots also can constantly occur simultaneously with several equipment of occasion, and therefore present this industrial radio remote controller can not satisfy the needs of industrial remote control.
The utility model content
The purpose of this utility model is to provide a kind of anti-interference type industrial radio remote controller of good in anti-interference performance.
This anti-interference type industrial radio remote controller that the utility model provides, comprise the transmitter and receiver that adopts secondary modulation, this transmitter and receiver comprises that respectively one contains the base band of microprocessor, described transmitter and receiver also respectively has a broadband receiver, transmitter and receiver base band separately all is designed to also contain the dual-core architecture of a digital signal processor, and described broadband receiver contains quadrature receiver, broadband operational amplifier, oscillator, frequency synthesizer at least; By the microprocessor in the transmitter base band key command is formed the serial command sign indicating number, after by digital signal processor telecommand being carried out spread spectrum, carry out the command channel coding by microprocessor again, form data streams, launch by transmission channel, the signal that broadband receiver receives carries out characteristics of signals by digital signal processor to be handled and analyzes, by the microprocessor guiding, through the transmission channel modulation channel to clear channel; The broadband receiver of receiver adapts to transmitting of transmitter and adjusts the channel that receives, the signal of broadband receiver being sent here by the digital signal processor in the receiver base band carries out characteristic processing and analysis, guiding by microprocessor, by the receiving cable of receiver the secondary demodulation signal that receives is input to digital signal processor and carries out spread spectrum demodulation, and be converted to the control signal of operating equipment by microprocessor, by interface circuit control signal is passed to instruction execution unit.
Because the utility model has all used broadband receiver in transmitter and receiver, what therefore the utility model adopted is the transmission duplex pattern, transmitter uses broadband receiver to make can help transmitter self adaptation judgement undesired signal characteristics, and is transformed into new clear channel work.Applicable broadband receiver technology in receiver can make receiver self-adaptation transmitter and adjusts the channel of reception, reaches the purpose of anti-co-channel interference.The base band of transmitter and receiver all is designed to dual-core architecture (digital signal processor and a microprocessor) working method, can improve signal handling capacity, carry out Signal Processing by Digital Signal Processing, analyze the characteristic of received signal, simultaneously the instruction and data that receives is handled, security fault appears in anti-locking system, the employing of double-core technology is technical in secondary modulation in addition, can increase spread spectrum to telecommand, further play the effect of anti-co-channel interference, such as: spread spectrum is got spread processing gain 10dB, reach the about 3dB of anti-co-channel interference in theory, when being the strong 3dB of the power ratio available signal power of co-channel interference signal, the system that can not influence normally receives.Therefore the utlity model has extraordinary interference free performance, especially anti-co-channel interference can satisfy the operation of commercial unit under the various complex situations.
