With the rapid development of electronic technology, various electronic switches and lighting control system products have emerged on the market. Some are short-distance electronic switches that use infrared remote control, and some are bus-type centralized control and decentralized control lighting control system products. The electronic switch using infrared rays is easy to be blocked by objects because infrared rays cannot penetrate opaque obstacles such as walls, and the remote control distance is short; for bus-type lighting control products, communication lines need to be re-buried. Users cannot use it. Some lighting control system products also use the combination of advanced LCD screen display and button control for centralized control and centralized status display, but when there are many controlled lamps, the small LCD screen cannot display all of them The status of the controlled lamps is displayed, so the user must turn the page to find it during use, which brings inconvenience to the user. Moreover, the target of this product has certain limitations, and it is difficult for the elderly in the family to accept this type of complicated product.

The core module of the single-chip microcomputer of the control part adopts the MSP430F149 chip of TI Company as the microcontroller, and is composed of conventional components such as crystal oscillators, capacitors, and resistors in the periphery. The MSP430F149 chip has the advantages of low voltage power supply and low power consumption.

The memory of the control part adopts the EEPROM chip AT24LC32 of ATMEL Company. The EEPROM chip can record data when the power is off, and can be rewritten by the microcontroller. Use this chip to store various status information.

The single-chip microcomputer core module of the actuator part adopts the AVR series single-chip microcomputer ATMEGA8L chip of ATMEL Company as the microcontroller, and is composed of peripheral crystal oscillators, capacitors, resistors and other conventional components. The ATMEGA8L chip has powerful functions, fast running speed, and internal integration of EEPROM and other functions.

The wireless receiving/transmitting integrated module adopts the CC1100 chip of CHIPCON Company, and matches conventional components such as capacitors, resistors, crystal oscillators on its periphery, and realizes wireless receiving and transmitting of data through the programming control of the microcontroller. That is to realize two-way wireless communication between the control part and the execution part. The wireless receiving/transmitting integrated module has a transmitting power of 10mW, the receiving sensitivity can reach -105dBm, and the wireless transmission adopts the 433MHz frequency band.

The relay switch execution module adopts the relay JZC-49F of Xiamen Hongfa Electronics Co., Ltd. The relay is small in size and the contact load can reach 5A current. The relay is driven by a conventional 8050 triode to realize the on and off of the power supply of the controlled lamps.

The operation is mainly controlled by touch screen input. There are 14 key areas designed and allocated on the touch screen. Of course, 18 or even 32 key areas can also be designed according to actual use requirements. Each button area can be defined as on-off key, scene key, and dimming key. For example, 14 keys define 10 switch keys, 2 scene control keys, and 2 dimming keys (two direction keys for up and down dimming). After such a design arrangement, the 10-way controlled lamps can be remotely controlled wirelessly through the 10 switch keys intuitively on the touch screen. The dimming key is for the currently operating actuator. As long as the currently operating actuator is a dimming actuator, the brightness of the light can be adjusted through these two dimming keys. Use the scene key to switch to the pre-set scene, which is suitable for different lighting environments, such as home, dinner, TV, meeting guests, reading and other scenes.

The actuator integrates two functions of wireless communication and control. It is designed for renovated houses and is fully compatible with ordinary mechanical switches. During installation, it is only necessary to replace the original mechanical switch with a two-way wireless remote control switch to realize switch control of indoor lamps or small electrical appliances. The two-way wireless remote control switch can realize two-way communication with the two-way wireless remote control. It can be controlled by the remote control or used independently without the remote control. There are light touch buttons locally for related operations. There is a corresponding status indicator light on the actuator panel. When the lamp is turned on, the indicator light is off, and when the lamp is turned off, the indicator light is on and emits blue light.

Two-way wireless remote control switch actuator short press (press and hold less than 1 second) the local key for switch operation; two-way wireless remote control dimmer switch actuator short press (press and hold for less than 1 second) local key for switch operation, and the key duration is 1 to 5 Local cycle dimming in seconds, you can adjust the brightness of the light at will, and at the same time, it can remember the brightness of the light to realize different scene functions. The brightness value of the light is stored in the EEPROM memory built into the core circuit of the single-chip microcomputer, which can be maintained even if the system is powered off, so that it can be restored to the state before power-off after power-on again.

The working principle of controlling the power switch of lamps or electrical appliances through the two-way wireless remote control is as follows: When you want to control a certain lamp (for example, the first lamp), touch the button area 1 on the touch screen on the two-way wireless remote control with your hands. , the generated control signal is sent to the single-chip microcomputer, and the single-chip microcomputer first judges the current state of the first lamp. If it is currently on, it will send a close control signal through the wireless receiving/transmitting module, otherwise it will send an open control signal. All actuators can automatically receive this wireless signal. When the first actuator judges that it is calling itself, it will drive and execute according to the open or close command, and the local indicator light will also display the current status; other actuators judge If you don't call yourself, you don't make any response. After that, the No. 1 actuator sends out the current status information through the wireless receiving/transmitting module on the actuator, and the wireless two-way remote controller will display the status on the corresponding indicator light after receiving the status information.

The working principle of controlling the power switch of lamps or electrical appliances through the local buttons of the actuator is as follows: When you want to control a certain lamp (for example, the first lamp), you only need to press the local button. Turn off the light, otherwise turn on the light. At the same time, the local indicator light displays the corresponding state, and then the single-chip microcomputer of the actuator sends the current state information through the wireless receiving/transmitting module, and the wireless two-way remote controller will display the state on the corresponding indicator light after receiving this state information.
