[0029] The lamp control module comprises a first AC-DC power module, a second AC-DC power module and a direct-current digital lamp control module, the input end of the first AC-DC power module is used for connecting 220V alternating current, the output end of the first AC-DC power module is connected with the direct-current digital lamp control module to provide DC12V working voltage; the input end of the second AC-DC power module is connected with 220V alternating current, and the output end of the second AC-DC power module is connected with the direct-current digital lamp control module to provide DC48V driving voltage; the direct-current digital lamp control module controls the driving of the lamps and lanterns outside the power distribution box through a group of DC48V power line carrier to turn on and off and dim;
[0030] The input end of the third AC-DC power module is connected with 220V alternating current, and the output end is used for the power supply of socket, curtain motor and VRV air conditioner;
[0031] The RCU main module includes an AC 220V line and a DC 48V line, an input end of the AC 220V line is used for connecting 220V alternating current, the AC 220V line has two output ends, one of the output ends outputs 220V alternating current to connect an external 220V alternating current socket, and the other output end outputs 12V direct current by an internal AC-DC circuit to supply power to an air conditioning panel, a scene panel, a door magnet, a probe and a dry contact device outside a distribution box through a wiring terminal; an input end of the DC 48V line is connected with one of the output ends of the third AC-DC power module, and an output end of the DC 48V line is used for connecting an external direct current exhaust fan.

[0034] Energy saving and environmental protection: compared with the traditional alternating current power supply mode, the low-voltage direct current power supply mode can better adapt to the use of renewable energy such as solar energy and wind energy, so that the overall power supply system is more energy saving and environmental protection.
[0035] Good dimming performance: compared with the alternating current power supply mode, the low-voltage direct current power supply mode can better realize the dimming function of the lighting system, so that the lighting effect is more flexible and diverse.
[0036] Cost saving: reducing construction cost, the direct current dimming mode only needs one set of power line to realize the control and power supply of the direct current lamps in the guest room, compared with the traditional DALI dimming (a proper noun) and 0-10V dimming (a proper noun) which need two sets of lines (one set of power line and one set of signal line), greatly saving the pipeline cost and labor cost.
[0037] In one embodiment, the first AC-DC power module is a DC 12V working power AC-DC power module: used for working power supply of the direct current digital lamp control module; 220V alternating current is input into the module, and 12V direct current of the module is output to the direct current digital lamp control module; the second AC-DC power module is a DC 48V / 480W AC-DC power module: used for power supply of the lamp driving control part circuit in the direct current digital lamp control module; 220V alternating current is input into the module, and 48V direct current of the module is output to the direct current digital lamp control module.

The 12V direct current output from the first AC-DC power module (12V working power supply) is input to the direct current digital lamp control module, so that the direct current digital lamp control module normally enters the working state. At the same time, the 48V direct current output from the second AC-DC power module (48V / 480W) is input to the direct current digital lamp control module, and the lamp outside the distribution box is driven and powered through the control of the direct current digital lamp control module. The module outputs 48V direct current to the same lamp and drive, and only one set of power lines is required.

The output end of the fourth AC-DC power module is used for powering the direct current television and direct current controlled socket outside the distribution box. The RCU main module is connected with the alternating current contactor to control the conduction and disconnection of the alternating current contactor. When the RCU main module fails, the conduction and disconnection of the alternating current contactor cannot be controlled. Therefore, whether the RCU main module fails can also be judged by whether the alternating current contactor can be conducted and disconnected.
[0042] In one embodiment, the AC contactor is used to turn on or turn off the power supply of the fourth AC-DC power module (48V / 1200W) by 220V AC. The on or off of the AC contactor is controlled by the RCU main module; 220V AC input to the AC contactor, the AC contactor outputs 220V AC to the fourth AC-DC power module (48V / 1200W); the fourth AC-DC power module (48V / 1200W): for the power supply of the DC TV, the DC controlled socket and other external color devices of the distribution box; the 220V AC output from the AC contactor is input to the module, and the 48V DC output of the module is output to the DC TV, the DC controlled socket and other external devices of the distribution box.

[0044] The working process of the low-voltage direct-current room power distribution control integrated box is as follows:
[0045] ① Direct-current digital lamp control module (for example, HQ-DC-2M model of Bonchi Intelligent Technology): 220V AC power supply is converted to 12V and 48V through the first AC-DC power module (12V working power supply) and the second AC-DC power module (48V / 480W) to provide working voltage and lamp driving working voltage for the direct-current digital lamp control module, respectively; the direct-current digital lamp control module controls the on-off and dimming of the lamp driving outside the distribution box through a set of 48V power line carrier;
[0046] ② RCU main module (for example, BZ-HU003A-S model of Bonchi Intelligent Technology): 220V AC power supply is input to the RCU main module and output from three parts. The 220V AC socket outside the distribution box is powered through the relay closure. The AC contactor control signal is released and closed through the relay to make the AC contactor in the power-off state (release state) and the power-on state (action state), thereby controlling whether the AC contactor outputs 220V AC. The internal AC-DC circuit outputs 12V, which is supplied to the air conditioning panel, scene panel, door magnet, probe, dry contact and other devices outside the distribution box through the terminal;
[0047] ③AC contactor: 220V AC power is input to the fourth AC-DC power module (48V / 1200W) through the AC contactor to convert 220V AC power to 48V to power the DC TV and DC controlled socket outside the distribution box. The AC contactor only acts as a switch and is used to indirectly control the opening and closing of the DC TV and the DC controlled socket.
[0048] ④Communication network: when the DC digital lamp control module needs to communicate with the RCU master module, it communicates through the 485 communication network. When the RCU master module communicates with the panel, door magnet, probe and other devices outside the distribution box, it communicates through the 485 communication network. When the RCU master module needs to upload data to the cloud or the cloud issues data to the RCU master module, it communicates through the Ethernet network to the floor switch. The RCU master module can issue commands to the air conditioning panel outside the distribution box, which then controls the DC air conditioner outside the distribution box, or the air conditioning panel outside the distribution box directly controls the DC air conditioner outside the distribution box.
[0049] ⑤Third AC-DC power module (48V / 600W): 220V AC power is converted to 48V by the AC-DC power module to power the 48V constant power socket, 48V constant power curtain motor, 48V constant power DC air conditioner outside the distribution box, and the DC exhaust fan outside the distribution box through the RCU master module control relay closure.
