Abstract
The utility model discloses a detection circuit board for a matrix panel. The detection circuit board comprises a detection loop, wherein the detection loop comprises a power supply and two relays which are connected in series, each of the relays is connected with a voltage-stabilizing diode in parallel, and normally-open switches of the two relays are connected with an output point of the matrix panel. The detection circuit board can be used for detecting various kinds of matrix panels, and has the advantages of simple structure, convenient detection and low cost.
Description
Technical field
The utility model relates to a kind of wiring board, is specifically related to a kind of matrix panel detection line plate, for all kinds of responsible numerically-controlled machine matrix panels are carried out to functional test.
Background technology
Along with lathe function from strength to strength, at practical function, again under cost-saving requirement, increasing customer selecting is used the numerically-controlled machine with matrix manipulation panel.Use matrix panel to bring a lot of whiles easily but to the verification band of matrix panel, to serve inconvenience.
At present, panel manufacturer generally has two kinds to the method for calibration of matrix panel, the first is to carry out verification according to the principle of matrix panel, respectively corresponding 2 addresses, the two ends of the input and output point of matrix panel, use the method for common access deconcentrator, detect like this one and input or output signal and just have two fixing corresponding signals and show, quality that like this can detection line plate, but this kind of method needs the input/output point on one-time detection matrix panel, detect slow, time and effort consuming.
Second method is to use corresponding system, inputs corresponding trace routine, and then system output detections result judges that the quality of wiring board, the method are detection methods the most conveniently at present.But many times, the first wiring board of producing always exists certain quality for topic, when use system detects, if run into quality problems, often occur burning out the phenomenon that fuse even burns out visual plant, as burn out I/O module ，Gei company and bring about great losses; In addition, if there is the system of often not using, this kind of method is just not easy to use.
Summary of the invention
The utility model object is to provide a kind of all kinds of matrix panels, the matrix panel detection line plate that easy to detect, cost is low of detecting.
For achieving the above object, the technical solution adopted in the utility model is: a kind of matrix panel detection line plate, comprise and detect loop, described detection loop comprises power supply, two relays of serial connection, described in each, relay is in parallel with a voltage stabilizing diode, and described in two, the normal open switch of relay and the output point of matrix panel are connected.
In technique scheme, described relay is provided with light emitting diode.
Above-mentioned matrix panel comprises that with detection line plate several detect loop, and each components and parts are welded on detection line plate, and described detection line plate is provided with cattle horn socket, for docking with matrix panel.
Preferably, described relay is selected 12V DC relay.
In technique scheme, described power supply is 24V direct supply.
In technique scheme, described voltage stabilizing diode is 12V voltage stabilizing diode.
It is example that the list of take detects loop, and principle of work of the present utility model is as follows:
When an input signal is connected, P1, D1 connect, relay K M1, KM2 average voltage under the effect of voltage stabilizing diode.After relay work, corresponding relay normally open switch is closed, and output point Y1 connects.Meanwhile, relay obtains when electric, the lumination of light emitting diode on it, thus break down in which bar loop of finding matrix panel.
Because technique scheme is used, the advantage that the utility model compared with prior art has is:
1. the utility model can be used for detecting all kinds of matrix panels, simple in structure, easy to detect, cost is low.
2. centre of the present utility model, with the form access of deconcentrator, is detected as long as the aviation socket of matrix panel is docked with the cattle horn socket of detection line plate like this, and plug is convenient.
Accompanying drawing explanation
Fig. 1 is the principle schematic in single detection loop in the utility model embodiment mono-;
Fig. 2 is the wiring diagram of the utility model embodiment mono-.
Wherein: 1, power supply; 2, relay; 3, voltage stabilizing diode; 4, the output point of matrix panel; 5, cattle horn socket.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
Embodiment mono-: a kind of matrix panel detection line plate, comprise and detect loop, shown in Figure 1, described detection loop comprises power supply 1, two relays 2 of serial connection, described in each, relay 2 is in parallel with a voltage stabilizing diode 3, and described in two, the normal open switch of relay 2 and the output point of matrix panel 4 are connected.
Wherein, described in two, relay 2 is respectively KM1 and KM2, and the output point 4 of matrix panel is counted Y1.
Described relay 2 is provided with light emitting diode.
As shown in Figure 2, above-mentioned matrix panel comprises that with detection line plate 15 are detected loop, and each components and parts are welded on detection line plate, and described detection line plate is provided with cattle horn socket 5, for docking with matrix panel.
In the present embodiment, described relay 2 is selected 12V DC relay.Described power supply 1 is 24V direct supply.Described voltage stabilizing diode 3 is 12V voltage stabilizing diode.
It is example that the list of take detects loop, and the principle of work of the utility model embodiment mono-is as follows:
When an input signal is connected, P1, D1 connect, relay K M1, KM2 average voltage under the effect of voltage stabilizing diode.After relay work, corresponding relay normally open switch is closed, and output point Y1 connects.Meanwhile, relay obtains when electric, the lumination of light emitting diode on it, thus break down in which bar loop of finding matrix panel.
The utility model can be used for detecting all kinds of matrix panels, simple in structure, easy to detect, cost is low.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvement or replacement, these improvement or replacement also should be considered as protection domain of the present utility model.
