The utility model which separates control from execution, enhances refuelling safety, and improves work environments is composed of an ultrasonic signal transmitter and an ultrasonic signal receiver. The utility model is characterized in that the ultrasonic signal transmitter is formed by that an oscillation circuit, a synthesizer A1, an ultrasonic transmitting head D1 and other electric appliances are connected with each other, wherein, the oscillation circuit is composed of an encoding integrated circuit U1, control switches K1 to K4 which are positioned at the input terminal of U1, resistors R1, R2 and a capacitor C1, and the synthesizer A1 synthesizes carrier signals generated by the oscillation circuit and output signals of encoding integration; the ultrasonic signal receiver is formed by that an amplifying circuit, a filtering circuit, an ultrasonic receiver D2 and other electric appliances are connected with each other, wherein, the amplifying circuit is composed of a decoding integrated circuit U2 and a triode T3, and the filtering circuit is composed of a capacitor C2 and a resistor R20.
Description
The utility model is the distant controller of a kind of petrol service station refueling control equipment, particularly gas filed.
The bunkering facilities of past petrol service station adopts the mechanical flow counting machine to control oiling more, in recent years, someone has invented " the quantitative automatic electric controller of fuel charger ", also there is the people that microcomputer is used for the gas filed automatic guidance, known to the designer, representational as Chinese patent No. 90211352.6 " the quantitative automatic electric controllers of fuel charger " and No. 91222958.6 " petrol service station microcomputer automatic control devices " etc.The bunkering facilities of these electric control, gas filed accuracy rate and gas filed work efficiency have been improved, but control all is to adopt wired mode, be unfavorable for separating of fuel charger and control cabin, for further improving the oiling work efficiency, improve and refuel and the controlled separation degree,, wish in the practice and can carry out remote control fuel charger to improve the gas filed fire savety and to improve the gas filed working environment.
The purpose of this utility model just provides a kind of remote controller that is applicable to computer or electron steering fuel charger.It separates control command and control (computer or electron steering) and execution machinery, and control command is decoded by the receiver of remote-control sytem reception that is added on the controller by the projector emission of remote controller again, will instruct input controller, control to carry out the machinery execution.
The utility model adopts the carrier of super sonic as control command, transmits and receives by hypracoustic, realizes above-mentioned remote operated purpose.Concrete technical scheme is: a kind of fuel charger ultrasonic remote control device, form by ultrasonic signal emitters and ultrasonic signal receptor, it is characterized in that: ultrasonic signal emitters is by the integrated circuit U 1 of coding, be positioned at the master cock K1～K4 of U1 input end, resistance R 1, R2, the oscillating circuit that capacitor C 1 constitutes, electrical equipment connections such as a synthesizer A1 that the oscillating circuit carrier signal that produces and the integrated output signal of encoding is synthetic and a ultrasonic emitting D1 form, control command inputs to U1 by K1～K4, U1 is according to the instruction of input, after by the software of having compiled and edited control command advance being handled, exporting synthesizer A1 to is penetrated by the ultrasonic emitting hair, master cock K1～K4 can be different and different according to selected U1, can be more than also being less than 4, and can constitute the input of a plurality of instructions by it, specifically decide by the needs of selected U1 and control; Filter circuit that the amplifying circuit that the ultrasonic signal receptor is made of decoding integrated circuit U2, aerotron T3, capacitor C 2 resistance R 20 constitute and the connection of ultrasonic receiver D2 electrical equipment form.The decoding software of decoding integrated circuit U2 is corresponding with coding, and through the defeated refueling control device of the control signal after the decoding, the control fuel charger refuels.
Such scheme of the present utility model has simply been realized the purpose of inventing, and circuit structure is simple, and dependable performance is with low cost.
Embodiment of the present utility model and description of drawings are in conjunction with being described as follows:
Fig. 1 is the block scheme that the utility model is used;
Fig. 2 is the scheme circuit of the utility model embodiment projector;
Fig. 3 is the scheme circuit of the utility model embodiment receptor.
Embodiment of the present utility model as shown in the figure, the signal input of the integrated circuit U 1 of the coding of ultrasonic signal emitters is by the power supply V that is connected in master cock K1～K4 back and through two component compressive resistance R5～R8, R9～R12 dividing potential drop constitutes, and power supply V is through master cock K1～K4 and distinguish forward-, series conducting diode B3～B6 with it to integrated circuit U 1 of coding and oscillating circuit power supply.Like this, only when control signal was imported, power supply was just given the power supply of U1 and oscillating circuit, and makes it work, and complete machine does not quit work when having the signal input, with brownout.NAND gate A2, A3, A4 connect respectively between the R1 of ultrasonic signal emitters oscillating circuit, R2, the C1 and on the mouth of oscillating circuit, to improve vibration, synthesizer A1 also is a NAND gate, have only when U1 and oscillating circuit have signal simultaneously, could realize carrier wave and promote a ultrasonic emitting D1 emission by NAND gate.The transistor amplifier of ultrasonic signal receptor constitutes the aerotron see-saw circuit by aerotron T3, R21, the connection of R22 electrical equipment.Integrated circuit U 1 of the coding of present embodiment and decoding integrated circuit U2 adopt PT2262 and PT2272-M6 integrated circuit respectively.A ultrasonic emitting D1 and a reception D2 are prior arts, have off-the-shelf to purchase, Gu no longer explanation.
