Background technology
At present, the highway refueling station industry development that China Petrochemical Industry, PetroChina Company Limited. be main body of take is rapid, but the many employings of the oil tank of these refuelling stations are buried, and petrol station various model monitors used are also just accomplished the Real-Time Monitoring of outside fuel-displaced situation, this just causes the leakage of underground oil storage pot bottom to be difficult to be discovered, not only cause larger leakage of oil economic loss and environmental pollution, and hold fire hazardous and blast.
The TLS-2 monitor that refuelling station was used under the existing China Petrochemical Industry/PetroChina Company Limited. in Areas in Shanghai City of take is example, the warning function that it the carries realization that only limits to just can be triggered when low oil level, high water stage appear in buried storage tank, the trigger alarm function not if there is oil level fluctuation among a small circle is regarded as normal phenomenon, cannot remind relevant staff's on-the-spot hidden danger of investigating that arrives in the very nick of time when this just causes tank surface to occur seepage or has stolen behavior to occur after staff comes off duty.
Summary of the invention
The present invention be directed to existing monitoring device and can only detect the data such as liquid level in oil tank, volume, can not be in the problem of oil tank PetroChina Company Limited. volume generation ANOMALOUS VARIATIONS alarm, a kind of heavy wool tank data fusion leakage warning device and data processing method have been proposed, can realize the system that storage tank leakage monitoring technology can realize leakage warning function, once tank body leakage, can give the alarm immediately, remind the operator on duty of refuelling station to check oil tank situation, get rid of in time the generation of potential safety hazard or the behavior of prevention stolen.
Technical scheme of the present invention is: a kind of heavy wool tank data fusion leakage warning device, comprise casing,, direct supply, audible-visual annunciator, casing front has alarm lamp, normal run indicator, power switch, non-self-locking test button, gear to set button, box house is single-chip computer control system, and there are RS232 port, outlet, audible-visual annunciator connector in casing side; Single-chip computer control system comprises the minimum control system of single-chip microcomputer, RS232 serial communication modular, audible-visual annunciator drive circuit module, LED diode circuit module and function button module; The minimum control system of single-chip microcomputer, by RS232 serial communication modular, the external refuelling station of RS232 port monitoring instrument, is carried out data communication; Send out the non-self-locking test button of self-test signal and set button and function button module input key signal to the minimum control system of single-chip microcomputer, set the gear of warning value, the minimum control system output of single-chip microcomputer control signal is controlled alarm lamp, normal run indicator; The minimum control system output of single-chip microcomputer control signal is controlled external audible-visual annunciator by audible-visual annunciator drive circuit module, and direct supply is powered to single-chip computer control system by casing outlet.
A kind of data processing method of heavy wool tank data fusion leakage warning device, gear is set by key assignments warning value and is sent into the minimum control system of single-chip microcomputer, the minimum control system of single-chip microcomputer gathers refuelling station's monitoring instrument data, each oil tank primary data reading is one by one decoded as initial floating data, and after filtering with merge after each oil tank primary data be stored in single-chip microcomputer internal storage unit; When wave phenomenon appears in oil tank level, tank leakage warning device is by comparing each oil tank real time data through data filtering and after merging and the primary data in storage unit, when being less than the warning value setting, fiducial value is considered to normal fluctuation, when being greater than the warning value setting, fiducial value is considered to unusual fluctuations, unusual fluctuations phenomenon occurs, and output alarm signal drives audible-visual annunciator by audible-visual annunciator drive circuit module.
Beneficial effect of the present invention is: heavy wool tank data fusion leakage warning device of the present invention and data processing method, can, in Real-Time Monitoring refuelling station oil tank level, detect exactly gasoline volume in tank body and whether ANOMALOUS VARIATIONS occur and determine whether to report to the police.Realized and controlled the diversified and intelligent of function, simplified circuit, reduced cost, improved stability, and can improve degree of accuracy by Data Fusion, at current energy scarcity, in the situation of oil supply anxiety, these works have good application prospect at energy field.
