Problems solved by technology
[0003] However, when performing on-site wiring, the wiring work of devices using communication chips usually also includes wiring the high-voltage terminals of the wiring port (so as to access high-voltage signals), and the number of terminals of the wiring port is also large, so the wiring It is easy for staff to make wiring mistakes, especially connecting the high-voltage signal corresponding to the high-voltage terminal to the low-voltage terminal.
Similar wiring errors can easily lead to damage to the communication chip inside the device, resulting in the failure of the device as a whole, which can easily cause users to be dissatisfied with the quality of the device.

The invention relates to a device with a wiring protection function and a control method thereof, and belongs to the technical field of wiring protection. The device comprises a switch part arranged between a communication chip and a low-voltage wiring terminal, a controller used for controlling the on and off of the switch part, and a voltage detection module used for detecting a voltage signal which is accessed by the low-voltage wiring terminal from the outside; wherein the controller is configured to determine whether the low-voltage wiring terminal is correctly coupled to the low-voltagecommunication bus based on the voltage signal detected by the voltage detection module, control the switch part to be off under the condition that the determination result is no, and control the switch part to be on under the condition that the determination result is yes.
Description
technical field [0001] The invention belongs to the technical field of wiring protection, and relates to a device with a wiring protection function and a control method thereof. Background technique [0002] When wiring on site, it is necessary to wire many devices using communication chips (such as various control terminals and monitoring terminals using communication chips based on RS485 protocol), including wiring many terminals of the device's wiring port, and of course Connect the low-voltage terminals corresponding to the communication chip of the connection port of the device. Under the condition that the wiring is completely correct, many devices can work normally. For example, the communication chips of each device work together to realize the information transmission between multiple devices. [0003] However, when performing on-site wiring, the wiring work of devices using communication chips usually also includes wiring the high-voltage terminals of the wiring p...
