[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0030] This utility model discloses a device for power line carrier communication control, such as... Figure 1 , Figure 2 As shown, it includes an upper cover 1, a base 3, a power line carrier circuit board 2, and signal lines; the upper cover 1 is positioned above the base 3, and the base 3 has a groove inside, in which the power line carrier circuit board 2 is placed.
[0031] The base 3 has two power line holes 4 on each side for passing AC power lines; the base 3 also has two signal line holes 5 on one side for passing signal lines. One end of the signal line passes through the signal line hole 5 and connects to the power line carrier circuit board 2, while the other end is used to connect to the electrical equipment.
[0032] The top cover 1 is equipped with a pairing button 11 and multiple pressing buttons 12. The pairing button 11 is connected to the power line carrier circuit board 2 and is used to trigger the power line carrier circuit board 2 to enter pairing mode. Before communication, the device and the controller confirm each other's identities and establish a communication link through a specific protocol. Pairing can be physically triggered by pressing the pairing button 11 (or by pressing it briefly after power-on), or it can be automatically triggered after the device is powered on. The form is not fixed. Its function is to cause a change in the level of the corresponding pin inside the device, triggering the firmware logic. The device broadcasts a specific signal to declare that it is in a pairable state. This pairable state has a time limit. If pairing is not completed within a certain time, the pairing state will be reversed.
[0033] The number and position of the multiple crimp keys 12 correspond one-to-one with the power line holes 4 and signal line holes 5. In this embodiment, there are six crimp keys 12, with two crimp keys 12 distributed at one end of the upper cover 1 and four crimp keys 12 distributed at the other end of the upper cover 1.
[0034] The power line carrier circuit board 2 is used to connect to an external AC power line; the power line carrier circuit board 2 is used to demodulate the signal on the AC power line and output it to the electrical equipment; and to modulate the status information of the electrical equipment and load it onto the AC power line.
[0035] The power line carrier circuit board 2 is provided with a plurality of elastic conductive mechanisms 6 corresponding one-to-one with the crimp key 12; one end of the elastic conductive mechanism 6 is elastically connected to the power line carrier circuit board 2, and the other end is connected to the crimp key 12, with a gap between it and the power line carrier circuit board 2 for passing through AC power lines or signal lines.
[0036] The crimp key 12 can be moved up and down. When the crimp key 12 is pressed, it causes the elastic conductive mechanism 6 to clamp the AC power line or signal line downwards, thus connecting the power line or signal line to the power line carrier circuit board 2. When the crimp key 12 is released, the elastic conductive mechanism 6 moves downwards under the action of the rebound force and releases, at which point the AC power line or signal line can be removed.
[0037] The upper cover 1 has six rectangular fastening holes 13, evenly distributed on both sides along its length, for secure fastening with the base 3. The base 3 has six fastening keys 31 evenly distributed on both sides along its length, corresponding one-to-one with the positions of the fastening holes 13. Each fastening key 31 includes an upper leaf and a lower leaf, with the upper leaf connecting above the lower leaf and protruding outwards at the connection point. After the upper cover 1 is fastened onto the base 3, the upper leaf engages with the fastening hole 13.
[0038] In this embodiment, a power line carrier module (PLC) is installed on the power line carrier circuit board 2. This module has two functional parts: a power supply part and a data transmission processing part. The power supply part is used to convert AC (220V) into low-voltage DC output through different switching power supply topologies. Different switching power supply topologies can meet the power input requirements of different countries and regions, such as 220V / 120V. This solution uses RC power supply. The power output mainly supplies power to the MCU main control unit and related control chips. The power line carrier power supply part is composed of rectifier circuits, inductors, capacitors, PCB boards and other components. The data transmission processing module can demodulate the carrier signal loaded on the power line. The demodulated control signal acts on electronic switches such as thyristors or relays to turn AC on / off, or output control signals corresponding to the device, such as (0-10V, PWM, DALI, etc.). It is composed of MCU, resistors, capacitors, inductors, signal conversion chips, thyristors or relays and other electronic switches and other components.
[0039] Installation process:
[0040] The AC power lines of the controller and the electrical equipment are respectively connected to the power line holes 4 on both sides of the base 3. One end of the signal line is connected to the signal line hole 5, and the other end is connected to the electrical equipment. Pressing the crimp button 12 causes the other end of the elastic conductive mechanism 6 to press downward, clamping the AC power line and the signal line. Then, resetting the crimp button 12 causes the elastic conductive mechanism 6 to move upward under the action of the rebound force and return to its initial state. This utility model can install wires without the aid of other tools, improving installation efficiency. The wiring is completed, and the installation of the power line carrier communication sub-node is also completed.
[0041] Work process:
[0042] In this embodiment of the wiring device, the power line carrier circuit board 2 demodulates the control signal loaded onto the power line by the controller and outputs a control signal. This signal can be a switching signal for the AC power line or a control command based on a specific control protocol, such as 0-10V, PWM, DALI, etc. The control signal is then transmitted to the electrical equipment via a signal line. When the remote controller is activated, the equipment operates according to the corresponding control command.
