Description

Remote control unlocking device

Technical Field

The utility model relates to a remote control field of unblanking, concretely relates to remote control unlocking means.

Background

The switch is an electronic component which opens a circuit, interrupts current or enables the current to flow to other circuits, and in a daily life environment, the current is allowed or forbidden to flow through the on-off control of the switch, so that the aim of controlling the starting or the closing of various lighting lamps or other various electronic equipment is further fulfilled, and the electronic equipment is controlled to enter or stop the running state.

In a traditional switch, the wiring design of an electronic circuit is mostly carried out on a wall body or the ground, and then the switch is fixed at a certain position, so that the installation process of the switch and the function of controlling other electronic equipment by the switch are realized. However, this switch arrangement

There are the following disadvantages:

1. the method comprises the following steps that a pre-wiring design is needed, a circuit is embedded in a wall body or a ground part in advance, then a switch is fixedly installed, once the wiring design is wrong in the wiring process or the switch position is not proper in the switch installation process, the whole circuit, the wall body and the like are needed to be installed and arranged again, the switch position is adjusted to be complex, and the position adjustment cost is high;

2. in the traditional indoor lamp switch, because a wall body is fixedly arranged, and the position is too high or the distance is too far, and the like, special people such as old people and children cannot effectively turn on or off the lamp through the switch;

3. in daily office or home environments, an individual needs to turn off various electronic devices and can only go to the corresponding switch position for control, and cannot realize remote turning on and off, so that the amount of exercise of the human body is increased;

4. the traditional switch is directly connected with a wire circuit, and the risk of incomplete alternating current cutoff exists after the switch is turned on and turned off;

5. the switch position is not adjustable, and the earlier stage process that realizes the switch installation is loaded down with trivial details, unable removal, and the flexibility ratio is low.

Therefore, in order to solve the above problems, a remote unlocking device is required.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model aims at overcoming the defect among the prior art, provide a remote control unlocking means, can solve effectual solution remote control switch to and the complicated problem of installation procedure.

The utility model discloses a remote control unlocking device, which comprises a transmitting end and a receiving end;

the transmitting end comprises a power supply, a switch key, an LED display lamp, an LDO, a radio frequency transmitting chip and a main controller, the output end of the power supply is connected with the input end of the LDO, the output end of the LDO is respectively connected with the input ends of the radio frequency transmitting chip and the main controller, the output end of the main controller is respectively connected with the input ends of the switch key, the LED display lamp and the radio frequency transmitting chip, and the radio frequency transmitting chip is connected with a transmitting antenna;

the receiving end includes LDO, radio frequency receiving chip and master controller, the output of LDO with the input of radio frequency receiving chip and master controller is connected, the output of master controller is connected with the input of radio frequency receiving chip respectively, receiving antenna is connected to radio frequency receiving chip, the output and the outside input of controlled equipment of LDO and master controller are connected.

Preferably, the input end of the radio frequency transmitting chip of the transmitting end is connected in series with a high pass filter and a low pass filter to form a band pass filter.

Preferably, the input end of the radio frequency receiving chip of the receiving end is connected in series with a low pass filter.
