Detailed description of the invention
A kind of oil-level measurement instrument, it is characterised in that include controller, sensor, ultrasonic emitting circuit, ultrasound wave reception circuit and launch change-over circuit; Wherein sensor is connected with controller; Ultrasonic emitting circuit is connected with controller; Ultrasound wave receives circuit and is connected with controller; Ultrasonic emitting circuit is connected with launching change-over circuit.
A kind of oil-level measurement instrument of the present invention, described controller is provided with RS232 serial communication interface, and serial communication circuit adopts MAX232 chip to carry out level conversion. Described controller adopts chip processor AT89S51 single-chip microcomputer. Power of SCM System voltage is 5V, and the excitation pulse signal that single-chip microcomputer sends is the 5V square-wave signal of about 8, and square-wave signal, through audion Q2, amplifies boosting to drive ultrasound probe to work then through transformator. Described sensor is temperature sensor. Described temperature sensor is digital temperature sensor. Described digital temperature sensor adopts DS18B20 digital temperature sensor, and direct current 5V powers, and monobus exports, pull-up resistor R6=4.7k ��, and monolithic can reading number temperature value by an I/O mouth. It is integrated with on CX20106 chip that described ultrasound wave receives circuit, and integrated chip CX20106 plays a significantly greater role in acceptance division parallel circuit. CX20106 is a widely used infrared ray detection reception special chip. Utilize ultrasound wave as infomation detection means, to realize the oil level detection in oil recovery factory's oil storage tank, and use method of least square to be analyzed measurement data processing. Being launched ultrasound wave by hyperacoustic emitter, sound wave runs into barrier back reflection, ultrasonic receiver receive echo. Measure and send train of pulse to the transmission time receiving echo-signal from ultrasound wave, owing to ultrasound wave transmission speed in same medium is constant, so according to time and the velocity of sound, so that it may calculate measurement distance. Sensor is not directly contacted with tested crude oil, and this measuring method has significantly high using value, particularly in middle-size and small-size oilfield exploitation enterprise. Installing input low, every a bite oil storage tank of oil recovery field will install a set of ultrasonic detector, the total quantity of oil storage tank is very big, so, put into low is very attractive for oil field. Next to that safe and reliable, crude oil has very strong volatility, and what it volatilized there are many imflammable gas. Certainty of measurement is high, and oil storage tank cross section is big, and certainty of measurement is low, will cause very big measurement error. Easy for installation, ultrasound wave oil-level measurement instrument volume is little, and in-site installation is very convenient.
