Abstract
The utility model provides a novel solar ultrasonic liquid level measuring instrument for an oil storage tank, which utilizes the ultrasonic echo ranging principle to achieve liquid level measurement, a high-range ultrasonic probe to expand the device measuring range, an NRF905 wireless data transmission chip block to achieve wireless data acquisition and a solar panel fixed at the top of the oil storage tank to supply direct current for a measuring device. The novel solar ultrasonic liquid level measuring instrument adopts the structure that a transmit-receive integrated ultrasonic sensor and a temperature sensor are respectively fixed at corresponding positions in the oil storage tank. When the system works, a singlechip provides an excitation signal for the ultrasonic sensor, and receives and processes a signal returned by the ultrasonic wave; the transmit-receive time difference of the ultrasonic wave and air temperature in the tank are analyzed to figure out the liquid level and the amount of oil remaining in the tank; all the measured parameters are sent to a handheld display device through a data transmitting module and a data receiving module and displayed by a liquid crystal display module; and when the parameters in the tank are abnormal, an alarm device is started to remind staff of dealing with the problem in time.
Description
Technical field:
The utility model relates to a kind of novel storage tank solar energy ultrasound wave fluid level measuring instrument.
Background technology:
Traditional storage tank metering method adopts manually metering mostly, and metering method inefficiency, precision are not high.Therefore be necessary to develop a kind of high-accuracy intelligent level gauging instrument.The ultrasonic liquid level measuring appearance then is a kind of selection preferably.The ultrasonic level gage range that uses at present all has only about 5m mostly; And general in the last few years large-scale floating roof tank jar is high all about 12m; Be difficult to satisfy the measuring requirement of large-scale oil storage tank; The traditional liquid level WT-MSR adopts the 220V Alternating Current Power Supply more simultaneously, and potential safety hazard is bigger, and complex circuit between measurement mechanism and easy ageing are damaged.To the deficiency of conventional ultrasonic wave fluid level measuring gauge, the utility model will use the high range ultrasonic probe, guarantee under the prerequisite of measuring accuracy the measurement range of lifting gear greatly.Change the traditional energy supply simultaneously, use green, safe sun power as energy resource supply.And the use wireless data transmission technology is changed the loaded down with trivial details of instrument wiring in the past, realizes the wireless collection of data, and is convenient and swift.
Summary of the invention:
The purpose of the utility model provides a kind of novel storage tank solar energy ultrasound wave fluid level measuring instrument.
The utility model solves the technical scheme that its technical matters adopted: it comprises several measuring terminals (1) and a hand-held display device (2); Measuring terminals (1) mainly by the solar panel that is fixed on the storage tank top (3) and Ni-MH battery (4), be fixed on the inner ultrasonic sensor (5) of storage tank and temperature sensor (6) and main control circuit (7) and data transmission blocks (8) and form, hand display device (2) and mainly form by data reception module (9), LCD (10), switching push button (11) and alarm (12).Utilize the ultrasonic echo range measurement principle to carry out contactless level gauging, utilize the measurement range of high range ultrasonic probe lifting gear, utilize NRF905 wireless data transmission chip to realize the wireless collection of data between measuring terminals and hand-held display device.Total system is made up of several measuring terminals and a hand-held display device; Measuring terminals is mainly sent by solar powered, temperature detection, temperature compensation, data and five modules of main control circuit are formed, and hand-held display device is mainly by Data Receiving, liquid crystal display, three modules of reporting to the police are formed automatically.
Solar panel is fixed on the storage tank top, and being connected to chargeable Ni-MH battery through driving circuit is that measuring terminals provides direct current.Transceiving integrated high range ultrasonic sensor is fixed on the storage tank inner tip; Temperature sensor is separately fixed at storage tank inner bottom part, middle part and top; And be connected respectively on the main control circuit oil plant temperature and air themperature when temperature sensor can detect measuring terminals work.Single-chip microcomputer in the main control circuit is that ultrasonic sensor provides pumping signal, and the ultrasonic signal that returns of reception, processes sensor.Ultrasonic signal is transmitted into the mistiming of reception and the distance dependent of barrier; The ultrasound wave that has just sent for fear of the direct reception of sensor; Can behind the emission ultrasound wave, one section time-delay be set; Single-chip microcomputer can calculate liquid level, the storage tank Fuel Oil Remaining through analyzing ultrasonic emitting to a mistiming of returning and a jar interior air themperature.Through data transmission, receiver module the parameters that records is sent to hand-held display device with the radiowave form, show through LCD MODULE again, carry out alert program simultaneously, reach and detect the purpose that unites two into one with monitoring.
The beneficial effect of the utility model is: utilize solar power supply circuit to cooperate rechargeable nickel-hydrogen battery, realized all weather operations of measurement mechanism, environmental protection.Utilize the ability to work of high range ultrasonic probe lifting gear, make it to be applicable to large-scale oil storage tank.Utilize NRF905 wireless data transmission chip to realize the wireless collection of data, convenient and swift.With respect to traditional ultrasonic liquid-level measurement meter, this device has environmental protection, super large range, advantages such as data acquisition.
Description of drawings:
Fig. 1 is novel storage tank solar energy ultrasound wave fluid level measuring instrument synoptic diagram.
Embodiment:
Be described further below in conjunction with accompanying drawing the utility model.
Among the figure, the 1-measuring terminals, 2-hands display device, 3-solar panel, 4-Ni-MH battery; The 5-ultrasonic sensor, 6-temperature sensor, 7-main control circuit, 8-data transmission blocks; The 9-data reception module, 10-LCD, 11-switching push button, 12-alarm.
The utility model uses solar powered technology, is that device is independent of external environment condition and running automatically, environmental protection.The utility model has adopted the high range ultrasonic probe again, has overcome the limitation that conventional ultrasonic wave liquid level gauge measurement range has only 5m.Use NRF905 wireless data transmission chip to realize the wireless collection of data, with tradition and liquid level gauge smaller volume, easy for installation, simple to operate.The utility model is significant with intellectuality to the robotization that improves the storage tank level gauging.
