Description

The carrier wave of automobile transmits and control

System of the present invention is relevant with the automobile electrical circuit, more detailed it, refer to that especially a kind of carrier wave of automobile transmits and control.Belong to the method and apparatus that the automobile circuit signal transmits and controls.

Generally speaking, the outfit of automobile all has sound equipment, car light, Warning light, the demist heater wire, rain brush or the like, must rely on battery power supply in the car, single passive equipment is done the action of control battery by switch, as shown in Figure 1, be that general automobile is connected on a switch and the car light at the two poles of the earth respectively with the electric wire that is connected in power supply, or power supply connection electric wire is connected on rain brush and the switch, each forms a loop, when being used as the motor-car light switch, car light can be done action bright or that put out, when start rain brush switch, the action that rain brush is also stirred or stopped, other is such as Warning light, the demist heater wire, sound equipment or the air cleaner that installs additional voluntarily, respectively form a loop between Car Burglar Alarm etc., all similar and power supply; Thus, under cover many electric wires in car, operator's saddle the place ahead is provided with many switches, and electric wire is many and complicated and disorderly, switch is set position difference in the each place, if install other current consuming apparatus (as branner, Car Burglar Alarm etc.) voluntarily additional, because car does not possess relevant circuit, dress could assemble in must being torn open, not only bother, also may destroy interior dress, even influence electric loop, disturb the normal operation of automobile.

Main purpose of the present invention is: provide a kind of carrier wave of automobile to transmit and control, it can simplify complicated disorderly electric wire in the present automobile, and utilize power lead to be written into high-frequency signals, control command is sent, make the signal checking circuit of holding power lead in addition, according to instruction control peripheral vehicle equipment, need not distribution or extra power supply.

The carrier wave of a kind of automobile of the present invention transmits and control, and it is power supply, power consumption peripheral equipment and the power lead that comprises in the car, and this power lead connects power supply supply power consumption peripheral equipment power supply; It is characterized in that: between each power consumption peripheral equipment and power lead, respectively be written into a signal checking circuit, and each signal checking circuit is controlled by a controller entirely, utilizing holds power lead to be written into high-frequency signals in addition, sending high-frequency signals to power lead signal by controller uploads, control command is sent, received and to the power consumption peripheral equipment of its correspondence, according to instruction control power consumption peripheral equipment by one of power lead signal checking circuit, simplify distribution, switch in view of the above, the purpose of reach easy assembling, easily controlling.

Advantage of the present invention is: each power consumption electrical equipment in just can Control of Automobile on a controller, simplified electric appliance wiring and switch in the car greatly, and assembling is simple, controls easily, and is easy to maintenance.

The present invention has following accompanying drawing:

Fig. 1 connects the schematic flow sheet of equipment for circuitry lines in the known automobile.

Fig. 2 establishes power lead and schematic block follow diagram thereof for the present invention connects.

Fig. 3 is applied to the schematic flow sheet of rain brush, car light and additional branner for the present invention.

Fig. 4 is the present invention's plan sketch that distributes in automobile.

Number in the figure is as follows:

10. controller 11. signal checking circuit

12. power consumption peripheral equipment 20. power supplys

Now lift preferred embodiment and conjunction with figs. is described as follows:

At first, see also Fig. 2 and cooperate Fig. 3, shown in Figure 4, the carrier wave of a kind of automobile of the present invention transmits and control, it is the power supply 20 that includes in the car, power consumption peripheral equipment 12, a power lead and a controller 10, this power consumption peripheral equipment 12 can contain sound equipment, rain brush, car light, de-fog, branner etc., except power supply 20 1 ends are connected to the power consumption peripheral equipment 12 with power lead, power supply 20 is held in addition in addition with power lead line one controller 10, controller 10 can send the rf carrier signal on power lead, this power lead is connected to a signal checking circuit 11, this signal checking circuit 11 links to single power consumption peripheral equipment 12 separately, each power consumption peripheral equipment 12 all is connected with a signal checking circuit 11, and each signal checking circuit 11 is subjected to this controller 10 controls entirely;

By above-mentioned device combination, the carrier wave of a kind of automobile of the present invention transmits and control, when controller 10 sends a rf carrier signal, this rf carrier signal is uploaded through power lead, control command is sent, after the signal checking circuit 11 on the power lead detects acceptance, to its cooresponding power consumption peripheral equipment 12, according to instruction control power consumption peripheral equipment 12; Therefore, steerman is as long as make needed instruction control on a controller 10, sending of the high-frequency signals that these are different to different signal checking circuit 11, and start each power consumption peripheral equipment 12, when on high-frequency signals sends, being stated from power lead to each signal checking circuit 11, only (its scope can between 1MHZ to 80MHZ) be just received signal checking on the characteristic frequency that signal checking circuit 11 sets, its power consumption peripheral equipment 12 is made instruction, so can utilize a controller 10, respectively power consumption peripheral equipment 12 is made the action of control, can simplify the assembling of power lead, remove many switches and be equipped with, make steerman can on a controller, operate power consumption peripheral equipment in the multiple automobile.

If in the time of will additionally adding in the entrucking other power consumption peripheral equipment 12, as air cleaner, as long as this branner is parallel to other power consumption peripheral equipment 12, and install a signal checking circuit 11 additional, can link on the controller 10, the rf carrier signal control that same controlled device 10 is sent, by its signal checking circuit 11, according to the open and close of instruction control branner and intensity etc., and need not write in reply assorted distribution or extra power supply, can not destroy the interior dress of former factory, also not influence the electric loop in the automobile, not disturb the normal operation of automobile.

Claims (1)

1, a kind of carrier wave of automobile transmits and control, and it is power supply, power consumption peripheral equipment and the power lead that comprises in the car, and this power lead connects power supply supply power consumption peripheral equipment power supply; It is characterized in that: between each power consumption peripheral equipment and power lead, respectively be written into a signal checking circuit, and each signal checking circuit is controlled by a controller entirely, utilizing holds power lead to be written into high-frequency signals in addition, sending high-frequency signals to power lead signal by controller uploads, control command is sent, receive and to the power consumption peripheral equipment of its correspondence, according to this power consumption peripheral equipment of instruction control by one of power lead signal checking circuit.
