[0002] When carrying out large-scale projects such as stage construction, a large number of terminal devices need to be deployed. Taking indoor stage construction as an example, cameras, lights, sound systems, sensors, ventilation equipment, etc. need to be deployed in all directions according to the angle requirements.

Detailed Implementation

[0013] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] Please see Figures 1-3 This embodiment discloses a relay control panel adapted to multiple terminals, comprising: The power supply terminal is connected to an external power supply, and the central control chip is electrically connected to the power supply terminal to obtain operating current; The input port of the central control chip is electrically connected to the control buttons and the communication port to receive control signals; Control signals include node start, node stop, and runtime; The output pins of the central control chip are electrically connected to the relay to supply operating current to the relay according to the control signal; The control button module is mapped to a relay.

[0015] In this embodiment, a single relay control panel can connect to multiple electrical devices and perform local control of the electrical devices, or achieve remote control through wired / wireless connection, so as to realize real-time start / stop control of specific electrical devices.

[0016] Alternatively, based on the start / stop node and runtime carried in the control signal, combined with the device clock, timed start / stop control can be implemented for specific electrical equipment.

[0017] As can be seen, based on the relay control panel, multiple electrical devices such as lights can be controlled in a comprehensive manner, reducing the number of control terminals. This also significantly reduces the amount of wiring work, reduces the probability of errors, and shortens the operation time.

[0018] As an optional implementation, the relay includes a control coil that responds to a control signal, a common terminal controlled by the control coil, and normally closed and normally open terminals respectively disposed on both sides of the common terminal. The common terminal and normally closed terminal are normally connected, the normally open terminal is left floating, and the relay is turned off; When the control coil is driven by a control signal, it attracts the common terminal and the normally open terminal to conduct, while the normally closed terminal is left floating, thus turning on the relay and supplying power to the electrical equipment connected to it.

[0019] Here, the relay is normally off, and only supplies power to the electrical equipment when driven by a control signal.

[0020] As an optional implementation, the terminal electrical equipment includes at least lighting fixtures, audio equipment, cameras, sensors, and ventilation equipment.

[0021] As an optional implementation, the control buttons are used to receive local input control signals and perform power-on / power-off control on their corresponding relays.

[0022] As an optional implementation, the communication port includes a communication socket and a communication antenna; The communication port is used to insert a communication cable to obtain control signals for wired transmission; The communication antenna is used to receive control signals transmitted wirelessly.

[0023] As an optional implementation, the central control chip communicates with the MQTT server via a communication port.

[0024] As an optional implementation, the remote terminal device connects remotely to the central control chip via an MQTT server to remotely transmit control signals.

[0025] Here, in addition to local control by pressing control buttons on the relay control panel, remote multi-terminal control can also be achieved through wired / wireless means, significantly improving the redundancy and versatility of the control scheme.

[0026] Compared with the prior art, this embodiment has the following beneficial effects: In this embodiment, a single relay control panel can connect to multiple electrical devices and control them locally or remotely via wired / wireless connections, significantly reducing the amount of wiring work in multi-device scenarios, reducing the probability of errors, and shortening the operation time.
