Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is a hardware system structure schematic diagram of the present utility model.
Fig. 2 is the flow chart of control program of the present utility model.
Among the figure: 1 is that display, 2 is that central processing unit, 3 is that coffret, 4 is that memory, 5 is that power-supply system and backup power system, 6 are that alarm, 7 is that air-introduced machine current signal acquisition interface, 8 is an inlet outlet pressure differential signals collecting interface.
The specific embodiment
As shown in Figure 1, the utility model fiber bag precipitator operational efficiency monitoring device, comprise: display 1, central processing unit 2, coffret 3, memory 4, power-supply system and backup power system 5, alarm 6, air-introduced machine current signal acquisition interface 7 and inlet outlet pressure differential signals collecting interface 8, central processing unit 2 links to each other with display 1, alarm 6, coffret 3, memory 4, air-introduced machine current signal acquisition interface 7, inlet outlet pressure differential signals collecting interface 8 respectively by lead, carries out the internal data communication; Power-supply system and backup power system 5 link to each other with display 1, central processing unit 2, alarm 6, coffret 3, memory 4, air-introduced machine current signal acquisition interface 7, inlet outlet pressure differential signals collecting interface 8 respectively by lead, to its power supply.After if power supply is power down, backup power system still can be given display 1, central processing unit 2, alarm 6, coffret 3, memory 4, air-introduced machine current signal acquisition interface 7,8 power supplies of inlet outlet pressure differential signals collecting interface.
Current signal collector and air-introduced machine current signal acquisition interface 7 link to each other by lead, and pressure difference signal collector and inlet outlet pressure differential signals collecting interface 8 link to each other by lead, carry out the external data communication.
Its data transmission procedure is: after air-introduced machine current signal acquisition interface 7 and inlet outlet pressure differential signals collecting interface 8 are gathered real time data respectively, data are passed to central processing unit 2, through dividing 4 the tunnel to transmit new control command after central processing unit 2 computings, wherein one the tunnel pass to alarm 6, the second the tunnel passes to memory 4, and Third Road passes to coffret 3, the four tunnel and passes to display 1, by display 1 video data, so periodic duty.
Current signal collector and pressure difference signal collector all adopt Signal Isolation Technology, and Signal Isolation Technology is all adopted in the input and output of computer system data, and the output of power-supply system and backup power system 5 also is connected with isolated gate and isolates.
Fig. 2 is the flow chart of the control program of computer system shown in Figure 1; At first, air-introduced machine current signal acquisition interface 7 is carried out real-time [collection of air-introduced machine current signal], by [current signal isolation processing] analog signal is changed into after the data signal and is stored in [air-introduced machine rated current] signal in the memory 4 and together enters [rate of load condensate judgement] and judge; Simultaneously, inlet outlet pressure differential signals collecting interface 8 carries out real-time [inlet outlet pressure differential signals collecting], by [pressure signal isolation processing] analog signal is changed into after the data signal and is stored in [inlet and outlet pressure standard value] signal in the memory 4 and together enters [pressure reduction judgement] and judge; Normal as [rate of load condensate judgement] or [pressure reduction judgement], then enter [operational efficiency judgement], extraordinary or [pressure reduction judgement] nothing pressure or superpressure then enter [synthetic determination] as [rate of load condensate judgement]; After [operational efficiency judgement], also enter [synthetic determination]; After entering [synthetic determination], decision data divides three the tunnel, and the first via enters [warning], and the second the tunnel enters [prompting operation suggestion], and Third Road enters [showing the efficiency of dust collection grade]; Extraordinary or [pressure reduction judgement] nothing pressure or superpressure as [rate of load condensate judgement], then [warning] and [prompting operation suggestion], as [rate of load condensate judgement] or [pressure reduction judgement] normally, and after having carried out [operational efficiency judgement], then [demonstration efficiency of dust collection grade].
