Embodiment
The need for meeting 1 self-raising tower crane completion different location, different task, the present invention is from liter is tower
Heavy-duty machine remote control system includes 4 kinds of remote controls (can be further added by according to need of work several, each can be made into multiple), this 4 kinds
The circuit structure of remote control is identical, and simply working frequency is different.Dual-audio instruction signal generating circuit in remote control
Core parts are dual tone phone machine dialing integrated circuit WE9178, and the input of keyboard uses single contact 4*4 keyboards.Its key with
Double-audio signal has one-to-one relationship.Wherein there is a key to be set to priority key.Oneself is risen when needing to use remote control
When derrick crane is operated, the priority key should be pressed first, other function keys are then pressed again, otherwise with remote control pair
It is invalid that self-raising tower crane carries out operation.When multiple remote controls are operated to same self-raising tower crane, press first
The remote control of priority key obtains the right to use to the self-raising tower crane, and the other remote controls for not obtaining the right to use are sent
Instruction ignore.As defined in being completed when the remote control for obtaining the right to use first after task, it is necessary to press a priority key again, release
It is rivals in a contest the right to use of the self-raising tower crane, so as to other staff using other remote controls to the self-raising tower crane
It is remotely controlled operation.This just efficiently solves and the use of self-raising tower crane is competed and interfered with each other between each remote control
The problem of.The function of other each keys can connect according to solid-state relay SSR output ends in romote controlled receiving system circuit in remote control
Depending on the function of the hand switch contact of the self-raising tower crane connect.
In normal operating, by any one function key, then WE9178 output end T will export corresponding dual-audio letter
Number, the pin of FDD400-1 modules 5 through being capacitively coupled in dual-audio transmitting command signals circuit.FDD400-1 modules and its periphery
Circuit constitutes radio signal radiating circuit, and double-audio signal is exported after being modulated by FDD400-1 inside modules circuit from 8 pin.
When romote controlled receiving system does not receive command signal, YN9101 four output ends do not have decoding data output, after
Electrical equipment ZS-01F can not work.The normally-closed contact conducting of relay, makes four each control ends of bilateral analog switch CD4066 all
Low level, analog switch is closed;The normally opened contact of relay is off, and makes each control of signal transmitting switch circuit
Input is high level, and each analog switch is in the conduction state, remote control command signal input circuit be in etc. instruction to be received
Signal condition.
Analog switch in any instant, each road instruction transmitting switch circuit only has wherein is in closure state all the way, its
Analog switch in its three tunnel instruction transmitting switch circuit is off, it is seen that any instant command decoder can only be to it
In all the way command signal enter row decoding.
First via control relay circuit is controlled by first via dual-audio command signal decoding circuit in romote controlled receiving system,
It controls the first via to instruct the break-make of the analog switch in transmitting switch circuit again simultaneously, and controls second road signal to pass respectively
Defeated on-off circuit, the 3rd road signal transmitting switch circuit, an analog switch in the 4th road signal transmitting switch circuit it is logical
It is disconnected, when first via remote control signal receiver circuit receives the corresponding signal of priority key so that first via dual-audio instruction letter
Four bit instruction data of number decoding circuit output are 1111, the director data be transferred in first via control relay circuit with
Door input, its output end is high level, so that the relay in first via control relay circuit obtains electric work, first
Analog switch conducting in road instruction transmitting switch circuit, while second road signal transmitting switch circuit, the 3rd road signal transmission
The disconnection of on-off circuit, an analog switch in the 4th road signal transmitting switch circuit, so only first via remote signal
The command signal that receiving circuit is received can control self-raising tower crane to work, and other three roads remote control signal receiver circuits are received
Command signal can not be transferred to command decoder input, it is clear that self-raising tower crane can not be controlled to work.Work as the first via
Remote control signal receiver circuit receives nonpreemption key（Operate the function key of self-raising tower crane work）Corresponding dual-audio
During command signal so that four bit instruction data of first via dual-audio command signal decoding circuit output are not all 1, the instruction number
According to be transferred in first via control relay circuit with door input, its output end be low level so that the first via after
Relay electric-loss in electrical apparatus control circuit is stopped, because relay ZS-01F has movement memory, contact self-locking, static state
The features such as not power consumption, bistable state, thus relay electric-loss be stopped after contacts status with electric work when contacts status
Identical, remote control being capable of normal operating self-raising tower crane by first via remote control signal receiver circuit.When first via remote control
When the corresponding remote control of signal receiving circuit no longer operates self-raising tower crane, it is necessary to press priority key, when the first via is distant
When control signal receiving circuit receives priority key corresponding signal so that first via dual-audio command signal decoding circuit is exported
Four bit instruction data be 1111, the director data be transferred in first via control relay circuit with door input, its is defeated
It is high level to go out end, so that the relay in first via control relay circuit obtains electric work, the contact shape of the relay
State is overturn, so as to discharge the control to self-raising tower crane, now other remote controls can be by pressing priority
Key is obtained to normal operating self-raising tower crane after the control of self-raising tower crane, in a word any moment can only have one
Individual obtain can operate self-raising tower crane to the remote control of the priority of self-raising tower crane.
