Wiring diagram of the intelligent distributed power manager

1. Introduction to Intelligent Distributed Power Manager:
The intelligent distributed power manager, also known as the "power controller", is a very important part of the conference central control system, because there are some devices in the conference central control system that cannot be directly controlled by the central control host. When it comes to controlling the power on and off of this part of the equipment, it is necessary to use the intelligent distributed power manager for power management.
Second, the working principle of intelligent distributed power manager:
The main components of the intelligent distributed power manager are controlled templates and strong relays. The RS-232 port of the intelligent distributed power manager is connected to the COM port of the conference console through a 9-pin serial interface cable.
When the power manager is operated through the touch screen, the conference console sends control data to the power manager. After receiving these control data, the intelligent distributed power manager interprets the data and performs actions relative to the data.
The strong relay of the intelligent distributed power manager has two states, normally open and normally closed, and the strong relay is connected to the live wire of the power line of the equipment, which plays a role as a power switch. The power switch is controlled by the touch screen through the conference central control host.
3. The connection mode between the intelligent distributed power manager and other devices:
1. The connection between the intelligent distributed power manager and the projection screen:
In order to realize the two functions of the projection screen up and down, two strong relays are required. The projection screen actually uses a forward and reverse motor to realize the lifting of the projection screen, and this motor has 3 power interfaces. Therefore, we connect the common end of the motor to the neutral line of the power supply, and the other two binding posts are connected to the normally open end of the strong relay and then to the live wire of the power supply.
Through the programming of the conference central control host and the central control power controller processor, the jog control of the two strong relays is realized.
2. Connection between the intelligent distributed power manager and the display
Connect the neutral power end of the monitor directly to the neutral wire of the power supply, connect the power end of the live wire to the normally open terminal of the strong relay, and then connect it to the live wire of the power supply.
Through programming and the control of the central control host of the conference, the control of this normally open and normally closed switching is realized.
