Automatic seek wire system device on described a kind of experiment porch, is characterized in that between described liquid crystal touch screen and data acquisition board also arranging the relay group.
Automatic seek wire system device on above-mentioned a kind of experiment porch, comprise system processing unit and connected transformer, transformer is connected with air switch, the system processing unit output terminal connects auxiliary reclay and AC control board successively, AC control board is connected with liquid crystal touch screen with air switch respectively, the output terminal connected system processing unit of described liquid crystal touch screen, arrange data acquisition board between liquid crystal touch screen and system processing unit.The utility model is by adopting above-mentioned technology; between system processing unit and liquid crystal touch screen, data acquisition board is set; judge by data acquisition board whether liquid crystal touch screen works; be whether wiring is correct; feed back to system processing unit; if wiring error; system processing unit is by controlling AC control board; make to control the liquid crystal touch screen outage; until wiring is when correct, then switches on, can automatically protect equipment and personal safety; make to examine the teacher to free fully the line inspection work that workload is huge and easily make mistakes, also facilitated teacher's management.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 1-air switch, 2-transformer, 3-system processing unit, 4-relay group, 5-liquid crystal touch screen, 6-data acquisition board, 7-auxiliary reclay, 8-AC control board.
Embodiment
Below in conjunction with Figure of description, the utility model will be further described:
As shown in Figure 1, automatic seek wire system device on a kind of experiment porch, comprise system processing unit 3 and connected transformer 2, transformer 2 is connected with air switch 1 and controls its energising or outage by air switch 1, described system processing unit 3 output terminals connect auxiliary reclay 7 and AC control board 8 successively, AC control board 8 is connected with liquid crystal touch screen 5 with air switch 1 respectively, the output terminal connected system processing unit 3 of described liquid crystal touch screen 5, between liquid crystal touch screen 5 and system processing unit 3, data acquisition board 6 is set, between described liquid crystal touch screen 5 and data acquisition board 6, relay group 4 also is set, air switch 1 of the present invention and AC control board 8, the mode of connection of liquid crystal touch screen 5 grades is three-phase four-wire system.
As shown in the figure, the course of work of the present utility model is: first open air switch 1, transformer 2 energisings, transformer 2 passes through to system processing unit 3, system processing unit 3 of the present utility model is the single-chip microcomputer STM32 of STMicw Electronics based on the Cortex-M3 kernel, STM32 controls AC control board 8 by auxiliary reclay 7, make the liquid crystal touch screen 5 on bench panel must not alternating current, student's liquid crystal touch screen on deck plate by experiment selects examination question, then enter experiment model, the student starts wiring, after the student has connect line on bench panel, click automatic line inspection button, whether the current student's wiring of detection is correct automatically by data acquisition board 6 application algorithms for STM32, and teacher computer is opened host computer and is seen that can monitor which bar line of student has connect more, that line has connect less, so repeatedly, after student's wiring is entirely true, STM32 is by controlling auxiliary reclay 7 and AC control board 8, make experiment table obtain electric, liquid crystal touch screen 5 can operate, at this moment the student may press " start button ", make whole experimental loop energising, the observation experiment phenomenon.
The utility model also arranges the relay group 4 that relay group 4 arranges alternating current 220V between liquid crystal touch screen 5 and data acquisition board 6, main is that major loop and data acquisition board 6 in order to make wiring on test panel separates, in order to avoid major loop causes damage to weak electricity systems such as data collection plate 6 and master control borads after connecting interchange 380V electricity, improve security performance.
Automatic seek wire system of the present utility model is mainly used in and exchanges in the forceful electric power experiment, before experimental loop powers on, search misconnection according to experiment content, connect more, the line connect less also uploads in the host computer of teacher's PC, only have when experimental wiring is entirely true and during by line inspection button, experimental loop (AC power) just can be allowed to energising, thereby avoided the damage of equipment to reach the injury to personal safety, and the reserved expansion of system is connected to Ethernet interface, 232 serial ports, 2.4GHz the various communication interfaces such as frequency range wireless module, be convenient to finally be built into the experimentation on network management chamber, it can be applicable to the maintenance electrician, Machine Tool Electric Appliance, PLC, servomotor, the relay contact, the experiment porchs such as building.
