Description
Technical field
The present invention relates to field of remote-control unit, be specifically related to a kind of telepilot using simulant electronic switch.
Background technology
In the automated production process of the products such as air-conditioning, colour TV, Set Top Box, use equipment is often needed to carry out automatic remote control to produced product, automatically to carry out inspection and the test of product.At present, different product needs to use different telepilots, is difficult to use telepilot and controls a different product; Or, need to utilize the original remote controller chip of product and program to carry out transformation and use.
Existing telepilot takes remote controller key to replace Digital Signals to use a teleswitch chip.Traditional method uses triode and relay, but due to the process chip of telepilot be matrix form scanning button, triode therefore can not be used to design electronic switch.And if use relay make electronic switch, due to relay mechanical contact contact time exist shake, will report an error during remote controller chip process, can not use.Therefore, the method generally implemented at present is, replaces the finger of people, carry out automatic remote control by controller with the depression bar of machinery.This method system is complicated, and cost is high, poor for applicability.
Summary of the invention
For solving the problem, the invention provides a kind of telepilot using simulant electronic switch, comprising signaling conversion circuit, simulant electronic switch integrated circuit, remote controller chip; Outside peripheral control unit is connected with the control signal input end of simulant electronic switch integrated circuit by signaling conversion circuit, being connected with remote controller chip input end by gauge tap pin of simulant electronic switch integrated circuit;
The output signal of described peripheral control unit, by being converted to the control signal of simulant electronic switch integrated circuit control signal input end after signaling conversion circuit, described control signal control simulation electronic switch integrated circuit is by the connection of gauge tap pin and remote controller chip input end and disconnection.
Further, the output signal of described peripheral control unit is through signaling conversion circuit is converted to high level time, and simulant electronic switch integrated circuit is connected with remote controller chip input end by gauge tap pin; In time being converted to low level, simulant electronic switch integrated circuit 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 simulant electronic switch integrated circuit control signal input end and controlled switch pin.
Further, the conducting resistance of the controlled switch pin of simulant electronic switch integrated circuit is less than 10 ohm.
Beneficial effect of the present invention is:
1., from the digital I/O control signal of outside, 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 completely isolated with controlled making pin.So can substitute completely.
2. traditional remote controller signal goes control cylinder or driven by motor mechanical shaft by button, and system complex, fault is high, difficult in maintenance.The present invention uses control signal to control electronic switching, and principle is simple, dependable performance.
3. the control time of traditional remote controller mainly limits by motor or cylinder, and the used time is longer.The present invention adopts integrated circuit, and Signal transmissions is fast, is quick on the draw quick.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present invention.
Embodiment
The invention provides a kind of newly replace artificial button to use a teleswitch the telepilot of chip with simulant electronic switch, this telepilot is simple, reliable, can realize using at a high speed.
Fig. 1 is principle of the invention block diagram.Described telepilot comprises signaling conversion circuit, simulant electronic switch integrated circuit, remote controller chip; Outside peripheral control unit is connected with the control signal input end of simulant electronic switch integrated circuit by signaling conversion circuit, being connected with remote controller chip input end by gauge tap pin of simulant electronic switch integrated circuit.
Signal transmissions closes: the output signal of described peripheral control unit, by being converted to the control signal of simulant electronic switch integrated circuit control signal input end after signaling conversion circuit, described control signal control simulation electronic switch integrated circuit is by the connection of gauge tap pin and remote controller chip input end and disconnection.
Specifically, namely be, from the output signal of peripheral control unit by being converted to 3.3V after signaling conversion circuit, be added to simulant electronic switch integrated circuit 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, and 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 the P pin of remote controller chip and D pin respectively, thus achieve and replace button press or discharge the function of rear connecting and disconnecting remote controller chip P pin and D pin by external control signal.Described peripheral control unit can be PLC.
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 just enough little (being generally less than 10 ohm, the resistance value much smaller than 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 the digital I/O control signal of outside, 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 completely isolated with controlled making pin.So can substitute completely.
2. traditional remote controller signal goes control cylinder or driven by motor mechanical shaft by button, and system complex, fault is high, difficult in maintenance.Native system uses control signal to control electronic switching, and principle is simple, dependable performance.
3. the control time of traditional remote controller mainly limits by motor or cylinder, and the used time is longer.The present invention adopts integrated circuit, and Signal transmissions 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 amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
