Description
Technical field
The present invention relates to telepilot field, be specifically related to a kind of telepilot that uses simulant electronic switch.
Background technology
In the automated production process of the products such as air-conditioning, colour TV, Set Top Box, often need to use equipment to carry out automatic remote control to produced product, to automatically carry out inspection and the test of product.At present, different product need to be used different telepilots, is difficult to use different product of a telepilot control; Or, need to utilize the original remote controller chip of product and program to transform use.
Existing telepilot takes remote controller key to replace the Digital Signals chip that uses a teleswitch.Traditional method is to use triode and relay, but because the process chip of telepilot is matrix form scanning button, therefore can not use triode design electronic switch.And if use relay to make electronic switch, because mechanical contact when contact of relay exists shake, remote controller chip will report an error while processing, and can not use.Therefore, the method for generally implementing is at present, with mechanical depression bar replacement people's finger, by controller, to carry out automatic remote control.This method system complex, cost is high, poor for applicability.
Summary of the invention
For addressing the above problem, the invention provides a kind of telepilot that uses simulant electronic switch, comprise signaling conversion circuit, analog switching ic, remote controller chip; Outside peripheral control unit is connected with the control signal input end of analog switching ic by signaling conversion circuit, being connected with remote controller chip input end by gauge tap pin of analog switching ic;
The output signal of described peripheral control unit, by being converted to the control signal of analog switching ic control signal input end after signaling conversion circuit, described control signal control simulation switch integrated circuit is connected and disconnection by gauge tap pin and remote controller chip input end.
Further, when the output signal of described peripheral control unit is converted to high level through signaling conversion circuit, analog switching ic is connected with remote controller chip input end by gauge tap pin; When being converted to low level time, analog switching ic is disconnected by gauge tap pin and remote controller chip input end.
Further, the output signal of described peripheral control unit is 24V, by being converted to high level 3.3V or low level 0V after signaling conversion circuit.
Further, electrical isolation between analog switching ic control signal input end and controlled switch pin.
Further, the conducting resistance of the controlled switch pin of analog switching ic is less than 10 ohm.
Beneficial effect of the present invention is:
1. from outside digital I/O control signal, through signaling conversion circuit, convert the operable high level signal of simulant electronic switch to.This signal is added to the control end input end of simulant electronic switch, and the controlled making pin of simulant electronic switch is just connected.The conducting resistance of the controlled making pin of simulant electronic switch is below 10 ohm, and the control signal input pin of simulant electronic switch and isolating completely with controlled making pin.So can substitute completely.
2. traditional remote controller goes to control cylinder or driven by motor mechanical shaft by button with signal, system complex, and fault is high, difficult in maintenance.The present invention uses control signal control electronic switching, and principle is simple, dependable performance.
3. the control time of traditional remote controller is limited by motor or cylinder mainly, and the used time is longer.The present invention adopts integrated circuit, and signal transmission is fast, is quick on the draw quick.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present invention.
Embodiment
The invention provides and a kind ofly new replace the use a teleswitch telepilot of chip of artificial button with simulant electronic switch, this telepilot is simple, reliable, can realize at a high speed and using.
Fig. 1 is principle of the invention block diagram.Described telepilot comprises signaling conversion circuit, analog switching ic, remote controller chip; Outside peripheral control unit is connected with the control signal input end of analog switching ic by signaling conversion circuit, being connected with remote controller chip input end by gauge tap pin of analog switching ic.
Signal transmission relation is: the output signal of described peripheral control unit, by being converted to the control signal of analog switching ic control signal input end after signaling conversion circuit, described control signal control simulation switch integrated circuit is connected and disconnection by gauge tap pin and remote controller chip input end.
Particularly, be, from the output signal of peripheral control unit, be converted to 3.3V after by signaling conversion circuit, be added to analog switching ic control signal input pin, this signal high level 3.3V will make the controlled making pin of simulant electronic switch: A pin and the conducting of Y pin, the low level 0V of this signal will make its A pin and Y pin disconnect.The A pin of simulant electronic switch and Y pin, be connected with P pin and the D pin of remote controller chip respectively, thereby realized the function of pressing or discharge rear connecting and disconnecting remote controller chip P pin and D pin with external control signal replacement button.Described peripheral control unit can be PLC controller.
It should be noted that necessary electrical isolation between the control signal of simulant electronic switch and controlled switch pin A and Y; Conducting resistance between simulant electronic switch A pin and Y pin must be with regard to enough little (being generally less than 10 ohm, much smaller than the resistance value of remote controller key conducting); Off resistance between simulant electronic switch A pin and Y pin must be just enough large.
Compare and use traditional automatic remote-control device, the present invention has following advantage.
1. from outside digital I/O control signal, through signaling conversion circuit, convert the operable high level signal of simulant electronic switch to.This signal is added to the control end input end of simulant electronic switch, and the controlled making pin of simulant electronic switch is just connected.The conducting resistance of the controlled making pin of simulant electronic switch is below 10 ohm, and the control signal input pin of simulant electronic switch and isolating completely with controlled making pin.So can substitute completely.
2. traditional remote controller goes to control cylinder or driven by motor mechanical shaft by button with signal, system complex, and fault is high, difficult in maintenance.Native system is used control signal control electronic switching, and principle is simple, dependable performance.
3. the control time of traditional remote controller is limited by motor or cylinder mainly, and the used time is longer.The present invention adopts integrated circuit, and signal transmission is fast, is quick on the draw quick.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
