In this embodiment, the authentication component includes a signal transmitter and a signal receiver, where the signal transmitter and the signal receiver are respectively disposed on the transmitter 2 and the sensor 1, that is, based on the detachable structure of the transmitter 2 and the sensor 1 of the blood glucose detection device 100, the authentication component is disposed on the transmitter 2 and the sensor 1, so that the signal transmitter is disposed on the sensor 1, and the signal receiver is disposed on the transmitter 2, for example, when the transmitter 2 is connected to the sensor 1, that is, when the blood glucose detection device 100 is in a connected state, the signal receiver receives a signal transmitted by the signal transmitter, and the signal transmitter and the signal receiver mutually authenticate to achieve pairing and authentication between the transmitter 2 and the sensor 1, and of course, it is also possible to dispose the signal receiver on the sensor 1, and dispose the signal transmitter on the transmitter 2 to achieve pairing and authentication between the transmitter 2 and the sensor 1, which is not limited herein.

It can be understood that by setting the signal transmitter and the signal receiver, the current connection state of the transmitter 2 and the sensor 1 can be monitored in real time through the signal strength and the bit error rate between the signal transmitter and the signal receiver, and when the signal strength is lower than the threshold value or the bit error rate exceeds the limit value, an alarm is triggered, which indicates that the circuit between the transmitter 2 and the sensor 1 is in a virtual connection or disconnection state at this time, that is, the circuit between the first conductive member 12 and the second conductive member 22 is unstable, so that the stable connection between the transmitter 2 and the sensor 1 is effectively improved, and the accuracy and the continuity of the blood glucose detection device 100 during detection are improved.

Meanwhile, by arranging the signal transmitter and the signal receiver, the situation that only the authorized sensor 1 and the authorized sensor 2 can be paired for use is ensured, and the transmitter 2 and the sensor 1 are prevented from being connected by mistake, for example, mutual interference is generated between the transmitters 2 and the sensors 1 in a plurality of blood sugar detection devices 100, so that errors and influences exist in detection results, and after the transmitter 2 is separated from the sensor 1 by a certain distance, the position of the transmitter 2 can be conveniently known by a user through the signal connection between the signal transmitter and the signal receiver.
