speeds of ultrasonic waves in different media, the distance between a transmitting surface and a reflecting surface of the ultrasonic sensor is fixed, the ultrasonic probe (transmit-receive integration) sends out sound wave pulse to reflecting baffle plate and then reflects back to the probe, where TOF method is used to measure time, TOF distance measurement method belongs to two-way distance measurement technology, it mainly uses signal in two asynchronous transceivers, where we use reflection surface mode to measure the distance between nodes, colloquially speaking, by transmitting infrared light source to the measured object, after the light wave is reflected back by the object, collected by sensor, system calculates the distance between the measured object and camera by calculating the pulse difference or time difference of the received light wave, we use reflection surface where the ultrasonic wave is controlled by MCU (micro control unit), and sent out from transducer, through fixed length flight pipeline, touch opposite reflection surface, then returned, received by sensor and transferred to MCU (micro control unit), further, the propagation speed of the current ultrasonic wave in the medium is calculated, the average flight Time (TOF) is calculated through a plurality of times of circulation, in a solution with fixed temperature and ammonia nitrogen concentration, TOF is almost fixed, the propagation speed of the ultrasonic wave is different in different mediums or different ammonia nitrogen concentrations, the propagation speed of the ultrasonic wave is different in the performance of the reaction in our equipment, namely the transmission and receiving flight time, so that the identification can be carried out, the maximum difficulty of carrying out water quality detection by using the TOF method is two, the first is that an ultrasonic wave propagation standard curve graph under different concentrations and temperatures is established, only a standard comparison is carried out on the curve with enough stability and accuracy, whether the current water quality is qualified can be accurately judged, and then the influence on the ultrasonic wave propagation speed is carried out under different temperatures, the second is that the detection time is set up by a large amount of data analysis, because the fixed-length flight pipeline is not very long, generally about five to ten centimeters, under the distance, the time is very short relative to the propagation speed of the ultrasonic wave, generally the time is in the nanosecond range, the ultrasonic propagation speed reflects the change of ammonia nitrogen concentration, the water quality of different ammonia nitrogen concentrations is quite sensitive, the time deviation is several tens of nanoseconds, the time acquisition is required to be accurate enough and stable enough, the ultrasonic wave control and detection chip with high precision and high sensitivity is adopted to control the emission of the ultrasonic wave in the solution, the time is strictly matched with the MCU (micro control unit), the reflected ultrasonic wave is also strictly matched with the MCU (micro control unit), the system error is reduced, the wiring of the whole circuit board is processed with equal length on the drawing, the control and detection are processed on algorithm in the MCU (micro control unit), the data are specially obtained, the data are filtered and washed, the data are obtained twice, the data are fitted for the time is most close to the real data, and the data are obtained through the curve fitting is carried out twice, and the best fitting is carried out for the time.
