The utility model can use a single DC power supply with the voltage of 12V to supply electricity. The additionally provided switch circuit can determine that whether the power supply energizes the main integrated block circuit or according to the state of a switch set, and thus the purpose of electricity saving is achieved. In addition, cipher can be sent to the memory storage circuit through the main integrated block circuit after set, and code data can not be lost because of the electric exhaustion of a battery. The utility model provides great convenience for users.

Description

A kind of telepilot

The utility model relates to a kind of telepilot that is used to control electronic product, specifically the improvement that the electronic circuit of telepilot is carried out.

Because electronic product generally use in daily life, sometimes the user need carry several telepilots, to control as garage iron rolling door, door lock for vehicle, air conditioner, the electric product that colour TV etc. are different, recently the someone designs the telepilot of improvement, can adopt single remote controller to set the different password of many groups, with the different receiving trap of difference remote control, bring sizable facility to the user, but because the telepilot domestic demand stores the multiple cipher that the user sets, main ic circuit in this telepilot runs off for avoiding the interior keying material of its RAM, almost continuation is supplied to power supply, therefore the user needs the frequent battery of changing, in case otherwise power drain and in time do not change battery, keying material just runs off in virtually, cause the user to operate, and do not open the door, or need all reset the puzzlement of password, its inconvenience is well imagined, another deficiency is the battery that 2 kinds of different voltages are housed in the considerable part telepilot, 12V voltage is used for signal transmission circuit, 3V specializes in main ic circuit to use, when the 12V undertension, remote control distance can shorten, the user more easily knows needs to change battery, if during the power shortage of 3V, Chang Yinwu early warning and cause keying material to disappear.

But the purpose of this utility model is to provide a kind of power saving, and the telepilot that can avoid the password in the main ic circuit to run off.

The technical solution of the utility model is achieved in that a kind of telepilot, it comprises housing, is contained in the plurality of keys on the housing, be contained in the telechiric device in the housing, this telechiric device mainly by direct supply behind electric resistance partial pressure, be connected to main ic circuit through diode, resistance again, main ic circuit also is connected with mu balanced circuit, S1-S5 switches set, radiating circuit, radiating circuit is connected with direct supply, it is characterized in that: be provided with on-off circuit between direct supply and main ic circuit, main ic circuit also is connected with the memory storage circuit.

The utility model compared with prior art has the following advantages:

1, owing between direct supply and main ic circuit, is provided with on-off circuit, whether this on-off circuit detector switch button S5 is automatically pressed by pressure, whether power to main ic circuit action with decision, and if when in the time of setting, pressing again by other arbitrary button S1-S4, will cut off power supply automatically, to reach the purpose of power saving.

2, for reaching the power saving purpose and avoiding the keying material in the main ic circuit to run off, when the keying material setting is finished, promptly can be stored in the memory storage circuit that is connected with main ic circuit automatically, when this telepilot is started shooting again, main ic circuit promptly can be grabbed back the keying material in the memory storage circuit earlier, so that control.

3, power supply adopts single 12V direct supply, saves the 3V battery of adorning in addition in quite a few telepilot of specializing in main ic circuit.

Fig. 1 is the circuit diagram of the utility model one embodiment

Below in conjunction with accompanying drawing present embodiment is further described.

The utility model mainly comprises housing, be contained in the plurality of keys on the housing, be contained in the telechiric device in the housing, this telechiric device mainly by the 12V direct supply after resistance R 5, R6 dividing potential drop, be connected to the RB3 end that model is W74C250 master's ic circuit 1 through diode D1, resistance R 2 again, the vdd terminal of main ic circuit 1 also is connected with the OUT end of mu balanced circuit 3; The RB0 end of main ic circuit is connected with radiating circuit 2 by resistance 1; The RC0 of main ic circuit, RC1, RC2, RC3 end is connected with button S1, the S2 of switches set 4, the end of S3, S4 respectively, and the other end of S1, S2, S3, S4 mutually and connect; The RD0 end of main ic circuit is connected with the end of the button S5 of switches set 4, and the other end of button S5 is connected with an end of resistance R 5; Direct supply also is connected with radiating circuit 2, being characterized as of its difference and prior art: be provided with on-off circuit 5 at direct supply and 1 of main ic circuit, this on-off circuit 5 is made up of two transistors, concrete connected mode is: the emitter of a transistor Q1 links to each other with an end (positive pole) of power supply, and its collector is connected with the input end (IN) of mu balanced circuit 3; The base stage of another transistor Q2 is connected with the end of diode D1, its grounded emitter, the base stage of transistor Q1 is connected with the collector of transistor Q2, in order to strengthen two bufferings between the transistors connection, also can add a resistance R 3 in the base stage of transistor Q1 and the inter-collector of transistor Q2; Main ic circuit also is connected with memory storage circuit 6, this memory storage circuit 6 is selected the 93C46 integrated package for use, it adopts with the connected mode of main ic circuit: the VDD3 of main integrated package, RD3, RE0, RE1, RE2 end are connected the VSS end ground connection in the memory storage circuit with VDD, D0, CK, CS, D1 end in the memory storage circuit 6 respectively.

The course of work of the present utility model is as follows: the 12V direct supply is through resistance R 5, R6 dividing potential drop, when switch key S5 is pressed when being path, the A point voltage is 3V, be connected to the base stage of transistor Q2 through diode D1, make transistor Q2 conducting, related transistor Q1 conducting, the 1N end acquisition voltage of mu balanced circuit 3 of making, and making its OUT end can stablize output 3V voltage, the vdd terminal that supplies main ic circuit is so that main ic circuit operate as normal; The pin RB3 of main simultaneously ic circuit also will export 3V voltage, make transistor Q2 after switch ammonium key S5 is decontroled by the user, can continue to keep the conducting of transistor Q2 and Q1 and the power supply of mu balanced circuit, and when main ic circuit in the time of qualifications (for example five minutes) as if obtaining any button S1-S4 in pin RC0-RC3 termination does not have the state that is pressed, be that VCC1 voltage can't be sent to main ic circuit, just can change the output of RB3 end and become electronegative potential, force transistor Q2 to open circuit, the related transistor Q1 that makes opens circuit, the OUT end of mu balanced circuit becomes electronegative potential, main ic circuit just can't move, and does not consume electricity, enters power down mode.Button S1-S5 in the switches set of the present utility model is for setting or the operator password use, when setting code, main ic circuit transfers to keying material in the EEPROM memory storage circuit thereupon and stores, so after entering power down mode, when as long as push switch S5 starts shooting again, main ic circuit just can be with the keying material in the EEPROM memory storage circuit, grabbed in the RAM that gets back to itself in advance, therefore, even the power drain of battery, keying material will because of can refresh memory function, still can complete preservation and do not run off, its power saving mode also can make the user must frequently not change battery.
