Description
Technical field
The utility model relates to a kind of emptying safety monitor that is applied to the refuelling station, and this emptying safety monitor is monitored the liquid level and the temperature of fluid, and send warning when liquid level is too high or too low in order in refuelling station's emptying process, belongs to the oil tank monitoring technical field.
Background technology
The security control of refuelling station's emptying process is the important step of gasoline station management.The product oil of refuelling station generally is by the product oil transport vehicle oil to be transported to the refuelling station from oil depot, then product oil is discharged in the storage tank of refuelling station.In the emptying process, if the staff at the emptying scene does not know the liquid level of product oil storage tank, oil spill accident takes place possibly then.The storage tank measurement monitoring system of current refuelling station can show the fluid level condition of storage tank, but the storage tank measurement monitoring system of refuelling station all is installed in the pulpit, and on-the-spot staff can't be known the fluid level condition of storage tank.
The storage tank measurement monitoring system of refuelling station, because system is less, general uneasy harness has the other instrument of the jar of explosion prevention function.The other instrument of day tank that is used for the refuelling station at present is also very simple, has only the liquid level of demonstration function, does not have control function and warning function.Even therefore a jar other instrument has been installed, also just indicate the product oil height of storage tank, the situation of superelevation appears, can not automatically close inlet valve.
Given this, we are necessary to design a kind of security monitoring instrument that can be applicable to the refuelling station.
Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, and a kind of security control instrument that can monitor oil product liquid level and temperature in the refuelling station is provided, and this instrument has explosion prevention function, can be applied to the explosive area of refuelling station.
The purpose of this utility model is achieved by following technical proposals:

The beneficial effects of the utility model are: this emptying safety monitor can be applied to the liquid level that the refuelling station measured and showed product tank in real time.When in the storage tank during the super setting value of product oil liquid level, this instrument has warning function and output signal inlet valve pass valve function; When finished product oil level height was lower than setting value, this instrument had warning function.
Description of drawings
Fig. 1 is the structural representation of emptying safety monitor.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the structural representation of emptying safety monitor.As shown in Figure 1, this emptying safety monitor comprises: power panel, safe screen, control panel, LCD display.
Described power panel is the power pack of emptying safety monitor, in order to each consumer in the emptying safety monitor is powered.
Described control panel is the major control part of emptying safety monitor.At least include control chip and data-storing chip on this control panel.This control chip is in order to control each equipment in the emptying safety monitor.The limit value that this data-storing chip is reported to the police in order to the superelevation of the configuration data of storage system and storage tank and the limit value of ultralow warning.This control panel links to each other with the liquid level instrument by safe screen.
Described safe screen is the electrical isolation plate, and it realizes the data transmission between control panel and the liquid level instrument on the one hand, realizes the electrical isolation between control panel and the liquid level instrument on the other hand.Why between control panel and liquid level instrument, safe screen be set, mainly be because liquid level instrument zone of living in belongs to the hazardous location, and the liquid level instrument itself is an inbeing safe explosion prevention equipment, the emptying safety monitor is to isolate explosion-proof type equipment, so need by this safe screen to guarantee the electrical isolation between control panel and the liquid level instrument.Described LCD display links to each other with control panel, and innage, water height, temperature, jar height in order to show the oil tank that the emptying safety monitor is managed reach parameters such as alarm setting value.
On described control panel, be provided with inlet valve interface and alarm interface, in order to connect the inlet valve and the alarm of oil tank, so that the Monitoring Data that control panel can be passed back according to the liquid level instrument is timely controlled inlet valve and alarm.
The emptying safety monitor of this spline structure has the function of the liquid level of real-time measurement and demonstration product tank in refuelling station's refueling process.When in the storage tank during the super setting value of product oil liquid level, this instrument has warning function and output signal inlet valve pass valve function; When finished product oil level height was lower than setting value, this instrument had warning function.The state of a plurality of product oil storage tanks can be measured and show to this equipment simultaneously, to adapt to different refuelling stations.
Because the designed emptying safety monitor of the utility model is operated in this zone that explosion danger is arranged, refuelling station.Therefore, we also are arranged with the explosion-resistant enclosure that one deck is isolated explosion-proof type at the skin of this emptying safety monitor.
In addition, we also are provided with the chip that resets with watchdog function on described control panel, are used for preventing the program fleet of control chip, and phenomenons such as system in case of system halt occur, to improve system reliability.
In addition, this control panel also links to each other with host computer by communication interface, is uploaded to host computer in order to the Monitoring Data of product oil that the liquid level instrument is measured, or accepts the configuration of host computer.Simultaneously, in order to improve system reliability, also can pass through the signalization isolation module between this control panel and the host computer, thereby further strengthen the security of this equipment with the electrical isolation between realization control panel and the host computer.
What in the present embodiment, described control chip adopted is the LM3S1138 chip of Luminary company.What described safe screen adopted is that model is the safety barrier circuit of GS8093B-EX.What described LCD display adopted is that model is the display of LR080AR.What described Signal Spacing module adopted is the RSM485CT chip.
In sum, the designed emptying safety monitor of the utility model can be applied to the liquid level that the refuelling station measured and showed product tank in real time.When in the storage tank during the super setting value of product oil liquid level, this instrument has warning function and output signal inlet valve pass valve function; When finished product oil level height was lower than setting value, this instrument had warning function.Persons skilled in the art are within any not creative transformation of doing under this design philosophy all should be considered as protection domain at this patent.
