Description

Technical Field

[0001] The utility model belongs to the technical field of lighting control, and particularly relates to a new type of remote control light-off system. Background Art

[0002] The main reason for the emergence of light-off devices in the current market is that some users did not consider installing intelligent remote control switches or double-control switches during decoration. When there is a need for remote control of turning off lights, a remote control mechanical switch has emerged, which can remotely control the turning on and off of lights.

[0003] Remote control switches are mainly divided into infrared remote control switches and radio frequency remote control switches, and both types of remote control switches have their own deficiencies: infrared remote control switches have high power consumption, high standby power consumption, require frequent charging or battery replacement, weak anti-environmental interference ability, and need to match the direction during application; radio frequency remote control switches have high standby power consumption, require frequent charging or battery replacement, and affect the battery life. Content of the Utility Model

[0004] The purpose of the utility model is to provide a new type of remote control light-off system to solve the deficiencies of the existing two types of remote control switches.

[0005] The technical solution adopted by the utility model is as follows:

[0006] A new type of remote control light-off system includes a light-off device and a remote control. The remote control includes a first battery, a key switch, and a radio frequency signal source that are electrically connected in sequence. The light-off device includes a second battery, a radio frequency energy receiver, an MCU, a load switch, and a servo. The second battery, the load switch, and the servo are electrically connected in sequence. The radio frequency energy receiver, the MCU, and the load switch are electrically connected in sequence. The second battery is electrically connected to the MCU, the MCU is electrically connected to the servo, and the radio frequency signal source and the radio frequency energy receiver establish a signal connection.

[0007] Further, the model of the MCU is STM32L051C8T6 or STM32L031G6U6.

[0008] Further, the radio frequency energy receiver is connected to an IO pin of the MCU through a diode, and the radio frequency energy receiver is directly connected to another IO pin of the MCU.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] The wireless remote control switch based on radio frequency energy transmission of the present utility model has no standby power consumption of the communication unit. The second battery is normally closed connected to the servo. Only when the MCU controls the load switch to conduct during remote control of turning off the light, the second battery supplies power to the servo, avoiding the standby power consumption of the second battery supplying power to the servo in the normally open state. Through the cooperation of the radio frequency signal source, the radio frequency energy receiver and the load switch, remote control of turning off the light with low standby power consumption is achieved. In addition, the remote control light-off system does not require a communication chip and will not generate communication standby power consumption, which can solve the problems of high standby power consumption, short switch life, and high frequency of charging and replacing batteries of the current light-off devices on the market.

[0016] The following will further describe the present utility model in detail with reference to the drawings. The following embodiments are explanations of the present utility model, and the present utility model is not limited to the following embodiments.

[0017] Embodiment: As Figures 1 to 2As shown in the figure, a new type of remote control light-off system includes a light-off device 2 and a remote control 1. The remote control 1 includes a first battery 11, a key switch 12, and a radio frequency signal source 13 that are electrically connected in sequence. The light-off device 2 includes a second battery 21, a radio frequency energy receiver 22, an MCU 23, a load switch 24, and a servo 25. The second battery 21, the load switch 24, and the servo 25 are electrically connected in sequence. The radio frequency energy receiver 22, the MCU 23, and the load switch 24 are electrically connected in sequence. The second battery 21 is electrically connected to the MCU 23. The MCU 23 is electrically connected to the servo 25. A signal connection is established between the radio frequency signal source 13 and the radio frequency energy receiver 22.

[0018] The model of the MCU 23 is STM32L051C8T6 or STM32L031G6U6.

[0019] The radio frequency energy receiver 22 is connected to an IO pin of the MCU 23 through a diode, and the radio frequency energy receiver 22 is directly connected to another IO pin of the MCU 23.

[0020] The radio frequency energy receiver 22 is connected to any one IO pin of the MCU 23 through a diode. Define this pin as pin A. The radio frequency energy receiver 22 is directly connected to another IO pin of the MCU 23. Define this pin as pin B. The first battery 11 supplies power to the radio frequency signal source 13 through the key switch 12. The second battery 21 is connected to the power supply pin of the MCU 23. The second battery 21 supplies power to the MCU 23 and the load switch 24 respectively. The load switch 24 is connected to another IO pin of the MCU 23. The MCU 23 controls the conduction and cut-off of the load switch 24, and thus controls whether the second battery 21 supplies power to the servo 25. The MCU 23 is in a sleep state by default. When the user presses the key switch 12, the first battery 11 supplies power to the radio frequency signal source 13. The radio frequency signal source 13 emits radio frequency energy. After the radio frequency energy receiver 22 receives the radio frequency energy emitted by the radio frequency signal source 13, the radio frequency energy receiver 22 outputs a wake-up voltage to wake up the MCU 23. When pin A receives the wake-up voltage, the MCU 23 pulls down the voltage of pin B directly connected to the radio frequency energy receiver 22 for 1 second. Pin B switches from the analog input mode to the push-pull output mode to prevent the key from failing due to the user pressing the key switch 12 multiple times in a short period. Then the MCU 23 controls the load switch 24 to conduct, and the second battery 21 supplies power to the servo 25 through the load switch 24. The servo 25 is connected to another IO pin of the MCU 23. The MCU 23 controls the servo 25 to achieve a state flip. The servo 25 flips to toggle the wall switch of the light, thus turning off the light. After turning off the light, pin B switches back to the analog input mode, waiting for the next voltage signal from the radio frequency energy receiver 22. The voltage of pin B is no longer pulled down. The MCU 23 records the current on / off state of the light. The load switch 24 is turned off, the servo 25 stops working, and the MCU 23 also enters the sleep state again, waiting for the next wake-up signal.

[0021] The wireless remote control switch based on radio frequency energy transmission of the present utility model has no standby power consumption of the communication unit. The second battery 21 is normally closed with the servo 25, and the second battery 21 only supplies power to the servo 25 after the MCU 23 controls the load switch 24 to conduct when remotely controlling to turn off the light, avoiding the standby power consumption of the second battery 21 for constantly supplying power to the servo 25. Through the cooperation of the radio frequency signal source 13, the radio frequency energy receiver 22 and the load switch 24, remote control of turning off the light with low standby power consumption is achieved. In addition, the remote control light-off system does not require a communication chip and will not generate communication standby power consumption, and can solve the problems of high standby power consumption, short switch life, and high charging and battery replacement frequencies of the current light-off devices on the market.

[0022] Wireless radio frequency energy transmission technology is a technology that uses radio waves for energy transmission. This technology can transmit electrical energy from the transmitting source to the receiving device without using physical connection lines. Although the wireless radio frequency energy transmission has large spatial losses, using this technology as a means of energy wake-up can effectively reduce or eliminate the standby power consumption of the wireless remote control switch, extend the service life, and reduce the charging and battery replacement frequencies. There is currently no wireless remote control switch based on wireless radio frequency energy transmission technology on the market.

[0023] The above embodiments are only exemplary descriptions of the present utility model and do not limit its protection scope. Those skilled in the art can also make partial changes to it, as long as they do not exceed the spiritual essence of the present utility model, they are within the protection scope of the present utility model.
