[0016] The data interaction module includes a second master control chip, a data receiving module and a first network module. The input terminal of the data receiving module is wirelessly connected to the output terminal of the data sending module of the plurality of data acquisition modules. The output terminal of the data receiving module is electrically connected to the input terminal of the second master control chip.

[0017] The data sending module and the data receiving module in this embodiment both use LORA modules, specifically SX1280 type chips. The SX1280 chip is a high-performance LORA Internet of Things wireless transceiver developed by Semtech Company, widely used in long-distance, low-power communication scenarios. The SX1280 series uses advanced radio frequency technology, with excellent linearity and anti-interference performance, becoming a leader in the 2.4GHz frequency band. It integrates time-of-flight calculation function, which is unprecedented in the ISM frequency band, significantly improving the positioning accuracy and communication security in complex environments, especially in key applications such as logistics tracking and personnel safety monitoring. The LORA module in the data sending module is enabled in data transmission (or sending) mode, and its input terminal is connected to the output terminal of the first master control chip to transmit data to the LORA module, and then the collected data is sent out by the antenna of the LORA module. The LORA module in the data receiving module is enabled in data receiving mode, and its antenna is used to receive the collected data sent by the data sending module. The output terminal of the data receiving module is connected to the input terminal of the second master control chip.

According to the circuit diagram, when the output end (PA7 pin) of the first master control chip outputs a low level, the transistor does not conduct, the coil of the electromagnetic relay does not conduct, and the normally closed end of the electromagnetic relay is closed. At this time, the medical equipment can form a loop and is in a conductive state. When the output end (PA7 pin) of the first master control chip outputs a high level, the transistor conducts, the coil of the electromagnetic relay conducts, the normally closed end of the electromagnetic relay is opened, and the normally open end is closed. At this time, the medical equipment cannot form a loop and is in a non-conductive state.
