Description
Technical field
The present invention relates to wireless network communication fields, in particular to for starting the nothing of each terminating machine when networking in zonule
Line power supply and mechanics of communication.
Background technique
Wireless data transmission technology has been more and more widely used in measurement and control area, and the feature of technology maximum is communication
Both sides save wiring, easy to maintain.Wireless data transmission technology provides flexible structure for the connection of modern test and control instrument and sets
Meter scheme, especially in some environment for being difficult to using conducting wire connection.The twin-stage TT&C system of this paper is consisting of a single chip microcomputer
Slave computer completes the collecting work of on-site signal, and transfers data to host computer (PC machine) by wireless communication module and carry out
It is further processed.Wireless data communication technology constantly heats up in industry control application at present, and various industries are being goed deep into wireless telecommunications.
Wireless communication technique completes point-to-point or point-to-multipoint data communication instead of data cable.Traditional signal cable transmission
The advantages of mode is that transmission speed is fast, and signal is isolated between each other.But since each signal occupies a bars cable, when
When station and more signal, the signal wire of occupancy is more, and construction wiring installation amount is big, not convenient for safeguarding.Once breaking down, overhaul non-
It is often inconvenient.With the continuous development of microelectric technique, wireless data transmission technology obtains more and more promotion and application, the skill
The maximum feature of art is that the both sides of communication can save wiring, has many advantages, such as at low cost, high reliablity, easy to maintain.But at present
The domestic and international technology is not also too many used in the computer measurement and control field.Host computer is realized using wireless data transmission technology
The transmission that signal is realized between communication and slave computer and spot sensor between slave computer, not only eliminates signal cable
And installation work, it so that the signal between system is transmitted and is connected greatly simplified.In industry control scene, the wireless connection of short distance
Have a wide range of applications demand, but a never good solution.Wireless communication technique is existing applied to industrial measurement and control
, it can reduce the difficulty and construction cost of construction, practical value with higher and preferable application prospect.The performance of its advantage
:
1. instead of the place that cable, especially cable used in the connection of a large amount of short distances can not reach, wireless communication has
Bigger advantage；
2. pervious application program can not make any or very little modification, upgrade cost is small；
3. being easily installed, safeguarding and extension；
4. reducing system building cost, this is also a distinguishing feature of wireless communication technique.
In recent years, wireless network becomes one of hot spot rapidly developed in industrial control field and industrial automation product not
The new growing point come.It is clear that configuration, installation, in terms of, the cost of wireless network is below wired network
Network.Mobile device can be easily accessed especially by wireless network, such as loading in logistics progress and transport are such as
According to wireless network, the working efficiency and accuracy of staff will be greatly improved.
In the zonule communication network being made of host and multiple wireless terminals, it may appear that need certain particular terminals
Captain's time is standby, but must recover immediately the case where communicating between host once receiving instruction.Under normal circumstances,
It is such it is standby be to realize in such a way that signal transmitter and receiver circuit in wireless terminal is powered operation always.If to
The machine time is longer, just has more electric energy to be consumed in the operation of signal transmitter and receiver circuit, if terminating machine quantity is more,
The waste of this electric energy is just more considerable.
The scheme taken to solve this problem at present, is mostly to be set as keeping by terminating machine in longer stand-by time
The operating condition that suspend mode but timing activate in short term, if receiving the signal of certain particular terminal machine of the selection of host transmission in activation,
The terminating machine starts and enters nominal situation；If terminating machine is not received by any selected letter in the certain time after activation
Number, then it returns in suspend mode, the activation signal transmitter and receiver circuit once again when next communication cycle.The shortcomings that this scheme,
It is to be in the state that can not be contacted in dormant period between terminating machine and host, if shortening dormant period to improve terminating machine response
Speed, then energy consumption is also higher.

The long code of machine characteristic, and by two it is soft enter/it is soft go out (SISO) decoder between carry out successive ignition and realize pseudorandom and translate
Code.His performance has obtained extensive concern and development considerably beyond other coding modes, and to current coding theory
Far-reaching influence is produced with research method, channel coding also enters a new stage therewith.
Further, the terminal node further includes accumulator, the wireless power which can will receive
It is used for after pulse storage to terminating machine short-duration power；Base station after sending wireless power pulse immediately send have identification coding to
The signal of specified particular terminal machine, corresponding terminating machine starts after receiving identification coding, into nominal situation.
Further, the wireless power transmit circuit is the controllable of transmitting 80 ~ 100kHz frequency electromagnetic wave
Resonance circuit, led to after rectifying and wave-filtering by alternating current one by transmitting coil and resonance capacitance group at shunt-resonant circuit,
And by the high frequency on-off of IGBT pipe control circuit to form voltage resonance in resonant tank.
