Abstract
The utility model discloses an on-line management system for the safety of storage tanks, which comprises a data centre server, a PLC (programmable logic controller) and sensors of the storage tanks, wherein the data centre server is connected with the PLC and is additionally connected with an Internet; and the PLC is respectively connected with signal output ends of the sensors of the storage tanks. The on-line management system has the advantages that through collecting, processing and intensively displaying information of operating parameters of the storage tanks, various data of oil products of the storage tanks are monitored and managed in real time, so time and labor are saved; monitoring data are accurate and the information can be obtained at the first time when the storage tanks encounter safety problems, so bigger safety accidents caused by the negligence of personnel are avoided; besides, storage tank operating records within a year can be reviewed; and in addition, the on-line management system has a simple framework, runs steadily and has high cost performance.
Description
[technical field]
The utility model relates to the storage tank safety monitoring technology, relates in particular to a kind of storage tank safety online management system that carries out safety management through on-line monitoring storage tank parameter.
[background technology]
The As China's oil industrial expansion, the increase of crude oil, finished oil reserves, domestic large-scale oil depot, oil tank battery get more and more.Petrol storage tank that these oil and petrochemical industry are medium-and-large-sized and storage tank are often concentrated in a large number and are disposed, in case have an accident causing huge personnel and property damage.
At present; State's implode or event of fire frequently take place, and have caused immeasurable loss for country, collective and individual, are that its security protection measure is not in place mostly and cause blast or event of fire; Perhaps safety defense monitoring system is paid little attention to and caused; Therefore country more and more payes attention to the fire fighting monitoring in inflammable and explosive place, requires also more and more strictness, so the automatic monitoring of the security protection of oil depot is paid attention to by people with the information management automation system day by day.In order to adapt to this development tendency, fire hazard and the leakage of inflammable liquid monitoring actual needs special according to oil depot should in time make up the safety on line monitor control system to the oil depot storage tank.
The safety monitoring work of present oil depot storage tank; Basically be to adopt the artificial DeviceMode that uses, carry out the storage tank check, the integrity of storage tank is assessed and predicted according to the API653 standard; And to the parts or the position of deterioration; Propose the maintenance suggestion, make it can continue safely to be on active service, check is carried out up to next time.
The weak point of prior art:
Manual pick is tested to storage tank according to the API653 standard with check implement, and formality is loaded down with trivial details, especially under a lot of situation of the storage tank quantity of oil tank battery, carries out storage tank is monitored with manpower merely, and efficient is lower, and because of artificial reason, the omission ratio is also higher.
[utility model content]
The technical matters that the utility model will solve provides a kind of storage tank safety online management system.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is that a kind of storage tank safety online management system comprises data center server, programmable logic controller (PLC) and tank sensor; Data center server is connected with programmable logic controller (PLC), and data center server also is connected with the Internet network; Programmable logic controller (PLC) is connected with the signal output part of tank sensor respectively.
As preferably, data center server is connected with programmable logic controller (PLC) through the tcp/ip communication mode.
Preferred as further, programmable logic controller (PLC) is connected with the signal output part of tank sensor through the RS485 serial bus respectively.
Preferred as further, tank sensor comprise appended sensor on the sensor that is installed on the storage tank and the storage tank instrument; The storage tank instrument comprises magnetostrictive liquid level apparatus, jar other table, explosion-proof liquid level transmitter.
The beneficial effect of the utility model is:
This system monitors and manage each association of storage tank oil product in real time through the storage tank trip information is carried out acquisition process and centralized displaying, and is time saving and energy saving; Monitoring data is accurate, can be when storage tank safety goes wrong the very first time obtain message, avoid because personnel's carelessness causes bigger safety misadventure; And can review the storage tank logout in a year; And framework is simple, and is stable, and cost performance is high.
[description of drawings]
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model storage tank safety online management system embodiment.
[specific embodiment]
As shown in Figure 1, present embodiment has all been installed the monitoring sensor and the measuring instrument that has sensor of exportable monitoring data signal, the latter such as magnetostrictive liquid level apparatus, jar other table, explosion-proof liquid level transmitter on the storage tank of required monitoring 1 and storage tank 2.The signal output part of these sensors sends a signal to programmable logic controller (PLC) (calling PLC in the following text) through the unification of RS485 serial bus; After handling, be sent to data center server, finally represent to the user through the Internet network with the form of WEB through data center server through ICP/IP protocol through PLC.The user can check the operational factor of storage tank through Telnet, in time grasps the safety case of storage tank.
According to aforesaid way, present embodiment can be monitored the multiple operational factor of a plurality of storage tanks simultaneously.
Present embodiment can be realized following function:
1) monitor the storage tank state in real time: display interface, monitor mean temperature and volume under storage tank oil level, water level, temperature, the liquid level in real time, parameters such as weight can provide various report form showings.
2) storage tank state Realtime Alerts: oil level bound, water level upper limit alarm.
3) inquiry and preservation historic state and incident: real time recording is preserved storage tank historic state, data such as oil level, position, boundary, temperature, volume, weight; Preserve and the inquiry time of fire alarming, the date of alert event and parameter at that time, data preservation 1 year have taken place in inquiry.
4) system parameter is set and is revised: tank battery, and single jar of setting, the oil product kind, safe altitude, the benchmark zero point of liquid level circle position and height alarming value are revised the date, revise people etc.
