Description

technical field

[0001] The invention relates to the technical field of equipment power protection, in particular to a method and system for controlling power supply of equipment. Background technique

[0002] The relay is an electrical control device, which is an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity meets the specified requirements. The relay has an interactive relationship between the control system and the controlled system, and plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit.

[0003] In traditional fish farming, it is necessary to manually go to the site to check the working status of the equipment, and manually control the switches of related farming equipment (such as aerators and feeders) through traditional relays, which often requires a lot of labor costs. Moreover, related farming equipme...

Examples

Embodiment 1

[0047] Embodiment 1 provides a device power control system. Such as figure 1 As shown, the equipment power control system includes a control module 1, a Modbus-RTU communication module 2, a relay module 3, an intermediate relay module 4, a current acquisition module 5, a power module 6 and a power module 7.

[0048] Optionally, the Modbus-RTU communication module 2 is connected to the control module 1, the current acquisition module 5 and the relay module 3 respectively. The intermediate relay module 4 is connected to the current acquisition module 5 , the relay module 3 and the power module 6 respectively. The electricity consumption module 7 is connected with the current acquisition module 5 and the power supply module 6 .

[0049] The working principle of the device power supply control system provided in Embodiment 1 may be as follows:

[0050] After the control module 1 is connected to the Modbus-RTU communication module 2, the control module 1 can send a current query...

Embodiment 2

[0071] Embodiment 2 provides a device power control method, which can be applied to the device power control system in Embodiment 1 above. combine Figure 1-2 As shown, the device power control method may include the following steps:

[0072] S11. The control module 1 sends a current query command and a level query command to the Modbus-RTU communication module 2 .

[0073] In a specific implementation process, the current query instruction is used to obtain the current value collected by the current collection module 5 , and the level query instruction is used to obtain the level state value of the relay module 3 .

[0074] In a specific implementation process, the current query command and the level status query command can be Modbus-RTU protocol commands.

[0075] In a specific implementation process, the control module 1 can regularly send the current query command and the level query command to the Modbus-RTU communication module 2 through the RS485 protocol.
