Accompanying drawing explanation
Fig. 1 is the structural representation that in the utility model, the petrol service station secondary oil gas based on power carrier is recovered in line monitoring system;
Fig. 2 is the structural representation of data trap;
Fig. 3 is the power carrier connection diagram that in Fig. 1, petrol service station secondary oil gas is recovered in line monitoring system.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
Shown in Fig. 1, the petrol service station secondary oil gas based on power carrier is recovered in line monitoring system, comprises gas flow counter, pressure transformer, data trap and monitoring equipment.
When practical application, gas flow counter is serially connected in the return line of nozzle in fuel charger, reclaims the flow of oil gas for measuring nozzle, and each or two nozzles configure a gas flow counter; Pressure transformer is by being connected on by threeway on the return-air house steward of the nearest fuel charger of oil tank or being arranged on the freeing pipe of oil tank, and for measuring the pressure of gas recovery system for oil and oil tank, whole petrol service station is installed a pressure transformer; Data trap is arranged on fuel charger inside, when the nozzle quantity of installing on every fuel charger is less than or equal to four, a data trap is installed in every fuel charger; When the nozzle quantity of installing is greater than four, need additionally installation data collector again on every fuel charger; Data trap is for gathering the oiling traffic pulse of the gas flow impulse singla of corresponding gas flow counter, the pressure signal of pressure transformer and fuel charger, gas liquid ratio when on-line monitoring nozzle refuels at every turn, and according to the leakproofness of pressure data judgement gas recovery system for oil; Gas flow counter and pressure transformer are connected respectively on data trap, and gas flow counter and pressure transformer are used for providing original signal for gas liquid ratio, liquid hinder isoparametric measurement; It is indoor that monitoring equipment is arranged on petrol service station, and whole petrol service station is installed a monitoring equipment.
As shown in Figure 2, data trap mainly partly consists of central controller, CPLD counting unit, memory cell and relay etc., can access at most 4 tunnels oiling impulse singlas, 4 road gas flow signals, No. 2 pressure transformer signals simultaneously, and there are 4 road relay output end mouths and two groups of data transmit-receive ports.Central controller adopts ARM microprocessor, and because the counting unit in microprocessor is limited, the utility model adopts CPLD counting unit to come pulse signals to carry out pretreatment, and CPLD counting unit is directly transferred to ARM by the data on flows after processing.The outgoing current of pressure transformer is 4～20mA, uses standard resistance to be converted to after voltage signal, by the built-in A and D converter of ARM, this signal is converted into digital quantity and processes.Acting as while finding system exception of relay output end mouth, is forced shutdown the power supply of this road binders rifle.Memory cell is used a slice E
2rOM realizes, and is mainly used to the data that arrange of storage of collected device.Owing to generally having the existence of a plurality of data traps in same petrol service station, therefore with an address toggle switch, indicate its address, address toggle switch is connected on central controller.
As shown in Figure 3, the built-in 24V Switching Power Supply of data trap, the alternating current in fuel charger can be converted into direct current (DC) is also internal circuit power supply.Between data trap and power carrier communication module, by serial ports, be connected, the power lead of power carrier communication module is directly connected with 220V source of AC.Indoor Video machine adopts an industrial touch-control all-in-one machine to realize, and monitoring equipment is connected with power carrier communication module by serial ports, can carry out communication by supply line and each data trap.Monitoring equipment regularly obtains gas liquid ratio data and pressure data from each data trap, when finding that oil gas is recovered in line monitoring system and sends alerting signal when abnormal and remind petrol service station operating personal to take corresponding measure, and can store, process, transmit data and check for supervisory management zone.
When practical application; the equipment of petrol service station inside can be connected between different phases conventionally; therefore the power carrier signal of data trap just can only be transmitted by specific phase line; in order to allow each can intercommunication between mutually; need to electronics carrier communication be installed across phase device at supply line end, the power carrier signal between each phase is forwarded and relaying.Indoor Video machine in use, only need access power carrier module any 220V supply line, and power carrier module can the RS232 serial ports by standard forward carrier signal, and monitoring equipment only need to operate serial ports.
Certainly; more than explanation is only preferred embodiment of the present utility model; the utility model is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the instruction of this specification sheets; that makes is allly equal to alternative, obvious form of distortion, within all dropping on the essential scope of this specification sheets, ought to be subject to protection of the present utility model.
