Further detailed description is done to the present invention with reference to embodiment.
Embodiment
With reference to Fig. 1, the electrical experimentses platform wiring of the present embodiment is corrected errors monitoring system, including can simulate sum with simultaneous transmission
Communication system between the experimental wiring hole of word signal and connecting line, microcontroller and PC and microcontroller.
With reference to Fig. 1, it is described can simultaneous transmission analog and digital signal experimental wiring hole as shown in figure 1~6, it is described can
L in the experiment connecting line such as figure of simultaneous transmission analog and digital signal13It is shown.
With reference to Fig. 2, each wiring hole on experimental bench is designed as two parts, and two parts are electrically isolated from each other, one
It is divided into the connecting line wiring hole (in figure shown in thick line) of actual circuit, another part is digital signal line wiring hole (fine rule in figure
It is shown)；Each experiment connecting line is also classified into two parts, two parts mutual insulating, a part is the company of connection actual circuit
Wiring, another part are the signal wire for transmitting connection signal；It is used to connect actual circuit in experimental wiring hole and connecting line
Part and the wiring hole in traditional experiment platform it is identical with connecting line, for turning on actual circuit.Increased newly in experimental wiring hole
The signal wire of the transmission connection signal increased newly in the numeral letter zygonema wiring hole and connecting line that add collectively constitutes the signal of experimental bench
System,
The experimental bench circuit system of signal system and reality is electrically isolated completely to, by the original wiring for realizing simple function
Hole is substituted for the wiring hole for including two parts of signal wire wiring hole and connecting line wiring hole, and original wire is substituted for and included
Connecting line and the two-part wire of signal wire, so, during each line, the circuit of reality is not only connected, also by signal line
Connection.As long as wire and wiring hole are reasonable in design, for the student of experiment, it, which tests experience, can accomplish and improve preceding nothing
Any difference.
With reference to Fig. 1, an I/O port of the signal wire wiring hole of each wiring hole on experimental bench and microcontroller is connected
Connect, the determining program that can be corrected errors by the wiring in microcontroller differentiates whether current experimental wiring is correct, in microcontroller
Wiring discriminating program of correcting errors it is as shown in Figure 3.After experimental wiring is completed, it is each that experimental bench is gathered by microcontroller first
Annexation between connection jaws.As shown in Fig. 2 being now to gather the annexation between experimental wiring hole 1 and 3, now lead to
Cross microcontroller I/O port and export high level to wiring hole 1, because hole 1 connects with hole 3 by wire, then microcontroller connection wiring
The port in hole 3 can detect high level, and other Port detectings export less than high level, searching loop to each wiring hole
High level, the level state for detecting other wiring holes just may determine that connection status between all wiring holes.
Because to a fixed experiment, under correct experimental wiring mode, the annexation in each experimental wiring hole is not
Uniquely, but correspondingly the wiring hole annexation of correct wiring can be enumerated, all wiring between each wiring hole
Form is also enumerable.The wiring hole annexation of all corresponding correct wirings can be first stored in microcontroller
In, after the annexation that microcontroller judges between all wiring holes, by the annexation of current experiment wiring hole and
The correct wiring relation of storage contrasts one by one, if microcontroller judges that the wiring hole annexation of this experiment correctly connects to be all
Connect one kind in mode, the line that just may determine that this experiment be it is correct, it is opposite, if we judge certain classmate's
Experimental wiring mode is not belonging to any one in all correct connection modes, and we just may determine that the line of this classmate is
Mistake, it is necessary to rewiring.
Microcontroller determine current wiring it is whether correct after, microcontroller can be by between PC and microcontroller
Communication system, by the positive false information of the wiring of this experimental bench, the coupling part of wiring error is transmitted to PC ends for testing in experiment
Personnel check, and facilitate the junction board of butted line mistake to carry out wiring correction.On the other hand, if experiment renewal, correctly experiment
Wiring hole connected mode changes, then can be by the communication system between PC and microcontroller, will be newest correct with the keys of PC mono-
The mode of connection is all downloaded in each experimental bench.
In summary, the present invention is a set of automatic monitoring system of electrical experimentses Platform Designing, and experimental wiring is completed in student
Afterwards, check whether wiring is complete and correct automatically, on the one hand alleviate the workload that experimenter checks wiring, accelerate experiment
Progress, it is often more important that the device damage caused by experimental wiring mistake and personnel can be avoided to injure.
