Abstract
The utility model discloses an intelligence liquid level automatic control device which adopts the technology of a single chip microcomputer to design an essential safety anti-explosion instrument according to the anti-explosion requirement of GB3836.1-83 and GB3836.4-83. The intelligence liquid level automatic control device has the functions of self-correction, detection, analogue display, self control, etc. The intelligence liquid level automatic control device adopts serial data to communicate, and simplify the junction cable. The utility model which has low cost is suitable for the liquid level automatic control of oil depots, gas stations, and oil tanks.
Description
The utility model discloses a kind of intelligent liquid level auto-controlling apparatus that is used for oil depot and storage tank liquid level control aspect, refuelling station, particularly a kind of application single-chip microcomputer technology, intelligent liquid level auto-controlling apparatus with detection, analysis, demonstration, control function.
At present, the storage tank of each oil depot, refuelling station will manually monitor liquid level when the input oil product, after liquid level reaches the upper limit, and the manual-lock motor.Use the utility model trace routine and requirement are solidified into software, give full play to the effect of single-chip microcomputer, replaced manually-operated, solved detection, demonstration and the automatic control of oil tank level in the oil transportation process preferably, saved manpower, avoided accident.
The utility model purpose is the applying electronic computer technology according to GB3836.4-83, the GB3836.1-83 requirement, and design is adapted at using in the explosion environment, has the oil tank level intelligent controller of multiple functions such as automatic detection, analysis, demonstration, control.
The utility model is finished in the following manner: with 8031 single-chip microcomputers is core, connect with detection signalling generator on being installed in oil tank by cable, detect on the signalling generator 8 floats are housed, tank diameter is divided into 8 five equilibriums, how much what float floated has reacted liquid level just, after floating, sends by float signal and teletransmission to main frame, main frame demonstrates liquid level with this signal Processing, when liquid level meets and exceeds in limited time, send cutoff command, so just finished automatic control of liquid level.
The utility model is owing to combine electronic technology and mechanical technique together, solved the problems such as detection, control, demonstration of oil tank level preferably.So simple in structure, easy to install, the reliability height.The example structure that will be described in detail below adopt, cost is lower, helps applying.
Below with reference to accompanying drawing the utility model is described in further detail:
Figure one is the utility model structural representation.
Figure two is the utility model host circuit figure.
Figure three is that the utility model detects the signalling generator circuit diagram.
Figure four is the utility model power supply and safety barrier circuit diagram
With reference to figure one, one is equipped with 8031 single-chip microcomputers is the main frame 1 that core is furnished with the LED diode displaying, detecting the signal Processing that signalling generator 2 is sent here, and the simulation of driving LED light emitting diode demonstrates liquid level, and detecting signalling generator can increase and decrease as required in 1 to 8 each scope.Intrinsic safety electric source 3 is powered to main frame by cable 5, and host computer control motor signal is sent to power supply, again by cable 6 control motors.
With reference to figure two, host circuit figure forms the main frame ultimate system by 80C31,74HC373,27C32.Constitute motor storage tank corresponding selection circuit by 74HC30 and combined switch, to adapt to the needs of the corresponding different motors of different oil tanks, form liquid level simulation display circuit by 74HC164,74HC374,74HC138, LED light emitting diode, form serial line interface by MC1413 and photoelectrical coupler, with the data double-way communication of control signalling generator.At first detection of code is delivered to the detection signalling generator after the start by the serial port output terminal, send the serial port input end back to by detecting signalling generator again, main frame compares detection of code of exporting and the data analysis of reading back, and it is correct and intact to check whether all joint sockets connect, and definite storage tank that should show.If socket is connected with the problem alarm indication, carry out operate as normal after, read by the serial port input end detecting the signal that signalling generator sends here, carry out logical process then, the driving LED simulation shows again.
With reference to figure three, detect the signalling generator circuit and form by parallel input string line output shift register and tongue tube, adhesive tongue tube K when float floats puts low level with the parallel input end of 4014 correspondences, and by the displacement form data serial is exported.
With reference to figure four, be host power supply and safety barrier circuit.Main frame and detection signalling generator are designed to inbeing safe explosion prevention equipment by GB3836.1-83, GB3836.4-83, and its power supply is supplied with through the associate device zena's safety barrier output of intrinsic safety.What mark the reliability assembly in the drawings is the safety barrier circuit.Power unit is installed in non-explosion-proof place, and main frame and detection signalling generator can be installed in explosive place and use.
Claims (2)
1, by main frame 1, the intelligent liquid level auto-controlling apparatus that detects signalling generator 2, power supply 3, constitute, it is characterized in that: with 8031 single-chip microcomputers be core by cable with detect signalling generator serial telecommunication, on main frame, be provided with the simulating display screen that the LED light emitting diode is formed.
2, according to the described intelligent liquid level auto-controlling apparatus of claim 1, it is characterized in that: power supply and safety barrier circuit 3 are installed in harbor, and power to main frame by cable, and main frame and detection signalling generator can be worked in explosive atmosphere.
