MCU converts the TDS value of liquid 400 in the pipe through analyzing this signal of telecommunication to judge whether intraductal liquid is physiological saline according to the TDS value. If the liquid in the tube is not normal saline, the alarm is wrong.

As shown in fig. 1, the light emitting unit 100 is a light emitting LED, and the light receiving unit 200 is a photosensitive receiving tube. The core original paper of the photosensitive receiving tube is a photosensitive resistor, when the light of the light-emitting LED irradiates the photosensitive resistor of the photosensitive receiving tube, the resistance value of the photosensitive resistor becomes small, in a limited range, the reduction degree of the resistance value is in direct proportion to the intensity of the light irradiation, namely the stronger the light, the smaller the resistance value is, and the photosensitive receiving tube converts the light signal into an electric signal by utilizing the characteristic of the photosensitive resistor.

Thus, in use, the water pump needs to be turned on so that liquid enters the tube. After the liquid in the pipe is judged, as an optional control mode: if the liquid in the tube is normal saline, the liquid in the tube can be sprayed out, if the liquid in the tube is not normal saline, the liquid in the tube can not be sprayed out, and an error is reported for prompting.

As shown in fig. 3, which shows an alternative control mode, first, initialization is followed by the following steps:

step 1, starting a light emission unit and a water pump, wherein the water pump is used for outputting liquid into a pipe; the light emitted by the light emitting unit is received by the light receiving unit and converts an optical signal into an electric signal;

step 2, ADC data acquisition is carried out on the electric signals in the step 1;

step 3, filtering the data in the step 2;

step 4, converting the data subjected to the filtering processing in the step 3 to obtain a TDS value of the liquid in the pipe;

step 5, judging whether the liquid in the pipe is normal saline or not according to the TDS value;

if yes, the water pump continues to output liquid, if not, the water pump is closed, and an error is reported for prompting. Convenient operation, easy observation for users and strong practicability.

In step 5, if the liquid in the tube is judged to be normal saline according to the TDS value, the water pump continues to output the liquid, whether water spraying is finished or not is detected in real time, if the water spraying is finished, concentration monitoring of the liquid in the tube is also finished, and if the water spraying is not finished, the steps 1-5 are carried out again. Continuous and real-time detection is realized, and the use reliability of the liquid is further improved.
