Embodiment one

Fig. 1 is a block diagram of an intelligent switch provided by Embodiment 1 of the present invention. The intelligent switch can be set in intelligent control networks such as intelligent buildings, and communicate with other intelligent switches in intelligent control networks such as intelligent buildings. Each intelligent switch can be connected to the corresponding load, so that the user can operate the nearby intelligent switch Control the local loads connected to the smart switch, or send load control signals to other smart switches, so that other smart switches control the state of the loads connected to it according to the load control signals, and realize remote control.

As shown in FIG. 1 , the smart switch provided in this embodiment includes: an address dial group 12 , an indicator light group 14 , and a central processing unit 18 . The address dial group 12 is used to set the address code, and the indicator light group 14 is used to correspondingly indicate the above address code. Specifically, the central processing unit 18 is used to receive the address code set by the address dial group 12 , and the indicator light group 14 is used to correspondingly indicate the address code under the control of the central processing unit 18 .

When multiple above-mentioned intelligent switches are installed in intelligent control networks such as intelligent buildings and intelligent home systems, the address code of the intelligent switch where it is located can be displayed through the corresponding indicator group, and the operator can intuitively observe the addresses of other intelligent switches. Code, so as to avoid setting the existing address code for the current smart switch, avoid communication failure, and quickly build a smart network; at the same time, it is not necessary to open the circuit board one by one to check the address code to troubleshoot the source of the fault during the maintenance process, avoiding complicated Easy to check and maintain.

Optionally, the smart switch of this embodiment also includes a button group 16 connected to the central processing unit 18 for triggering the central processing unit 18 to generate a load control signal, and the above-mentioned indicator light group 14 is also used for the control of the central processing unit 18 The lower part corresponds to the trigger state of the indicated button group 16 . As shown in FIG. 1 , when the central processing unit 18 determines that the button group 16 is triggered, it can control the corresponding indicator light 14 a to light up to indicate that the button 16 a is triggered.

Optionally, each key of the key group 14 is provided with an identification film 11 for identifying the local load and/or scene mode corresponding to the key. Each identification film 11 can be pasted on the surface of the corresponding key. For example, when the button 16a is used to trigger the smart switch to control the local load living room lamp, the words or patterns of "living room lamp" or other identification information may be printed on the identification film thereon. When the button 16b is used to trigger the smart switch to turn on scene one, the words or patterns or other identification information of "scene one: curtain off, bedroom light on, side light on" can be printed on the label film thereon. In this way, during the maintenance process, combined with the indicated address code and the display of the identification film, the fault range can be quickly determined and the maintenance efficiency can be improved. After the corresponding smart switch is checked by the code, the button 16b can be further checked, but the buttons that have nothing to do with the curtains do not need to be checked, and the scope of the check is very small.

Each local key in the key group 14 is specifically used to trigger the central processing unit 18 to control the state of the corresponding local relay, and then control the local load connected to the local relay. The central processing unit 18 is also used to control the state of the local relay corresponding to the load control signal for remote control when receiving the load control signal for remote control sent by other intelligent switches, and then control the local load.

For example, the central processing unit 18 is used to judge whether the operated buttons in the button group 14 are currently used to control local loads or are used to remotely control other intelligent switches. The state of the relay corresponding to the controlled local load, when the operated button is currently used for remote control of other smart switches, the load control signal is sent to the other smart switches via the short-distance wireless communication module 15 . After receiving the load control signal, other intelligent switch control devices control the state of the relay corresponding to the load connected to it.

Other smart switches send security scene control signals. For example, when the infrared device 20 senses that someone is approaching, the central processing unit 18 generates the security scene control signal and sends it to other smart switches through the short-distance wireless communication transmission module 15. Moreover, the central processing unit 18 is also used to control the load connected to the intelligent switch of this embodiment to be in a security state by controlling the on-off of the relay group 13 when receiving a signal of someone approaching.

For example, when the load of a relay connected to the relay group 13 is a curtain, and the curtain is in an open state under the security state, the central processing unit 18 controls the corresponding relay to close, so that the curtain is opened. As another example, when the load connected to another relay is a lighting lamp, and the lighting lamp flashes at a certain frequency in the security state, the central processing unit 18 controls the corresponding relay to close-open at a frequency, so that the lighting lamp flashing.

By installing an infrared device on the smart switch and controlling the load connected to it to be in a safe state according to the infrared sensing result, the smart switch can be used to control the load under normal conditions, and can be used as an alarm device in a safe state without additional control The cost is low, and the load connected to the smart switch is not easy to remove, and most of them are distributed in multiple positions in the space, which can realize the combination of various load states, and it is difficult for intruders to avoid, so the security effect is better.

Optionally, when the smart switch of this embodiment cannot transmit signals through the short-distance wireless communication module due to installation distance, wall barriers, etc., when the central processing unit 18 receives a signal that the infrared device 20 senses that someone is approaching, it will pass The serial bus communication module 17 sends security scene control signals to other smart switches communicating with the smart switch of this embodiment.

Optionally, the smart switch of this embodiment may also include a buzzer 21, which is connected to the central processing unit 18, and the central processing unit 18 is also used to trigger the buzzer 19 when receiving a signal that the infrared device senses that someone is approaching Buzzer alarm. Combining the buzzer alarm with the form of controlling the load to be in a security state further improves the security effect.

Optionally, the central processing unit 18 is also used to control the load connected to the smart switch of this embodiment to be in a safe state by controlling the on-off of the relay group 13 when receiving the security scene control signal sent by the above-mentioned other smart switches . Therefore, when a plurality of smart switches of this embodiment are set in a smart building, when the infrared device of any smart switch senses that someone is approaching, the smart switch will not only control the load connected to itself to be in a safe state, but also pass a short The distance wireless communication module or the serial bus communication module sends security scene control signals to other smart switches, and when other smart switches receive the security scene control signals, they can control the load connected to it to be in a security state.
