The utility model has following actively useful effect:
The utility model adopts distributed control structure, monolithic unit cooperation way, and this device has the advantages that cost is low, reliability is high, opening is good.
Description of drawings:
Fig. 1 is a structured flowchart of the present utility model.
Fig. 2 is the utility model data acquisition unit structural drawing.
Fig. 3 is the utility model main control unit and data acquisition unit group connection diagram.
Embodiment:
Below in conjunction with accompanying drawing structural principle of the present utility model, principle of work are explained in detail.
With reference to Fig. 1, a kind of SCM Based distributed monitoring device, comprise the data acquisition unit group, the data input pin connection device group of data acquisition unit group, the data output end of data acquisition unit group connects main control unit 2 by serial communication interface, at least two data collecting unit 3 composition data groups of acquisition units, at least two equipment 4 constitution equipment groups, main control unit 2 is connected to Ethernet by ethernet controller, top management machine 1 also links to each other with Ethernet, and realization main control unit 2 is connected with top management machine 1.
With reference to Fig. 2, equipment 4 comprises filtering circuit 6, photoelectric isolating circuit 9, the analog quantity of input inserts filtering circuit 6, the output terminal of filtering circuit 6 links to each other with the input end of multi-way switch 7, the input end of the output termination A/D modular converter 8 of multi-way switch 7, the output terminal of A/D modular converter 8 links to each other with single-chip microcomputer 5 by data bus; The switching value of input connects photoelectric isolating circuit 9, and the output terminal of photoelectric isolating circuit 9 links to each other with the input end of latch 10, and the output terminal of latch 10 links to each other with single-chip microcomputer 5 by data bus; The switching value of single-chip microcomputer 5 outputs connects photoelectric isolating circuit 11, the output relay termination 12 of photoelectric isolating circuit 11; Watchdog module 13, serial communication module 14 and memory module 15 chips link to each other with single-chip microcomputer 5.
With reference to Fig. 3, main control unit 2 links to each other with the data acquisition unit group by serial line interface RS_485, adopts the multi-computer communication mode to connect, and the RS_485 interface chip adopts MAX3085.The A of the MAX3085 of main control unit 2 end and B end link to each other with the B end with the A end of the MAX3085 of each data acquisition unit 3 respectively, and between the A of main control unit end and the B end and the A of first data acquisition unit 3 holds and B connects the resistance of 120 Ω between holding respectively.
Principle of work of the present utility model is as follows:
During equipment 4 work; each data acquisition unit 3 is realized the collection of 15 road input analog amounts and 16 road input switch amounts respectively; and whether working properly according to collection result and system operational parameters judgment device, if equipment breaks down, send control signal corresponding equipment 4 is protected.
Main control unit 2 is finished the demonstration of the real-time demonstration of all data acquisition units 3 data and time recording, the inquiry of historical data, time and system's setting, is resetted and function such as the setting of equipment operation parameter, password setting, system time are proofreaied and correct, required collecting unit is provided with.The user is the number of specified data collecting unit 3 as required, and revises the number of desired data collecting unit 3 in system is provided with, and 2 data acquisition units to customer requirements of main control unit carry out operations such as 3 data transmission and demonstration.
