Embodiment 1 of the present invention provides an intelligent switch control device, which can be installed in an intelligent building and networked with other identical intelligent switch control devices in the intelligent building. For ease of description, the embodiment of the present invention refers to the relays and loads connected to the intelligent switch control device of this embodiment as local relays and local loads, and the relays and loads connected to other intelligent switch control devices are referred to as remote relays and remote loads. load.

As shown in Figure 1, the intelligent switch control device provided in this embodiment includes:

The button group 12 , the relay group 14 corresponding to the button group 12 , the short-distance transmission module 16 and the CPU 18 , the CPU 18 is connected to the button group 12 , the relay group 14 and the short-distance transmission module 16 .

Each relay of the relay group 14 is a local relay, which is used to connect home appliances such as lighting lamps, intelligent curtains, and fans. Each button in the button group 12 is 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, and one or more buttons of the button group 12 can also be set to interact with other intelligent switches. The keys in the control device are paired to realize the control of the remote relay when the keys of the intelligent switch control device of this embodiment are operated.

For example, the central processing unit 18 is used to judge whether the operated buttons in the button group 12 are currently used to control the local load or to control the remote load. Control the state of the relay corresponding to the local load. When the operated button is currently used to control the remote load, the remote control command is sent to other intelligent switch control devices connected to the remote load through the short-distance transmission module 16. After receiving the remote control instruction, other intelligent switch control devices control the state of the relay corresponding to the load connected to it (that is, the above-mentioned remote load).

When networking multiple intelligent switch control devices, the network can be established according to the installation area. For example, the intelligent switch control devices installed on the first floor form the first network, and the intelligent switch control devices installed on the second floor form the second network. Second group network.

If other intelligent switch control devices where the remote relay is located are in the same network as the intelligent switch control device of this embodiment, the central processing unit 18 sends the above remote control instructions to other intelligent switch control devices through the short-distance transmission module 16 .

The serial bus module 17 is used for sending the remote control instruction to other intelligent switch control devices when the central processing unit 18 determines that the operated key is currently used to control a remote load. For example, if the smart switch control device where the remote relay is located is not in the same network as the smart switch control device of this embodiment, the central processing unit 18 sends the remote control command to other smart switch control devices through the serial bus module 17 .

Through the above method, even if the transmission distance of the short-distance transmission module 16 is limited, or the wall is blocked, it is convenient to use the local key to remotely control the remote load.

For example, when the local load power of one or more relays in the access relay group 14 is adjustable (such as LED lighting), the relay is also connected to the power adjustment circuit, and under the trigger of the corresponding power adjustment key 19, the central processing unit 18 can control parameters such as the output current or voltage of the power regulation circuit, and then adjust the power of the local load, for example, the brightness of the LED lighting lamp.

Optionally, the intelligent switch control device of this embodiment also includes an address dial group 15, connected to the central processing unit 18, for setting the address code, and sending the address code to the central processing unit 18, the address code is used to determine The transmission frequency band of the short-distance transmission module 16 . Using the address dial group 15, the same transmission frequency band can be set for the short-distance transmission modules 16 of the same network to facilitate mutual receiving and sending remote control instructions, and through the address dial group, the networking mode can be easily adjusted, for example As long as the dialing switch of the address dialing group 15 is used to change the dialing address, the intelligent switch control device of this embodiment can be transferred from the current networking to other networking.

Optionally, the intelligent switch control device of this embodiment further includes a set of indicator lights 13 corresponding to the set of keys 12, and each indicator light of the set of indicator lights 13 is respectively connected to the central processing unit 18 for displaying the operation status of each key. Specifically, the central processing unit 18 adjusts the display state of the corresponding indicator group according to the operation state of each key. Each indicator light can be arranged on the back of the corresponding button. When a certain button is operated, the indicator light on the back will emit light through the button, which can indicate which button is currently being operated.

Of course, assuming that the intelligent switch control device in this embodiment is the first intelligent switch control device, the first intelligent control device can also receive other intelligent switch control devices (such as the second The remote control command sent by the intelligent switch control device), and judge whether the remote control command matches the key on it, if it matches, control the state of the local relay corresponding to the key matching the remote control command, if not, pass the short-distance transmission module Or the serial bus module sends the remote control command to other intelligent switch control devices (such as the third intelligent switch control device), so that other intelligent switch control devices control the state of their relay groups, and then control the access to the other intelligent switch control devices. the state of the load.
