Detailed description of the invention
For making object of the invention process, technical scheme and advantage clearer, below in conjunction with the present inventionAccompanying drawing in embodiment, is further described in more detail the technical scheme in the embodiment of the present invention. AttachedIn figure, same or similar label represents same or similar element or has identical or similar from start to finishThe element of function. Described embodiment is the present invention's part embodiment, instead of whole enforcementExample. Be exemplary below by the embodiment being described with reference to the drawings, be intended to for explaining the present invention, andCan not be interpreted as limitation of the present invention. Based on the embodiment in the present invention, those of ordinary skill in the artDo not make the every other embodiment obtaining under creative work prerequisite, all belonging to the present invention's protectionScope. Below in conjunction with accompanying drawing, embodiments of the invention are elaborated.
In description of the invention, it will be appreciated that term " " center ", " longitudinally ", " horizontal strokeTo ", 'fornt', 'back', " left side ", " right side ", " vertically ", " level ", " top ",The orientation of the instruction such as " end " " interior ", " outward " or position relationship are based on orientation shown in the drawings or positionPutting relation, is only the present invention for convenience of description and simplified characterization, instead of the dress of instruction or hint indicationPut or element must have specific orientation, with specific orientation structure and operation, therefore can not be interpreted asLimiting the scope of the invention.
The object of the invention is the active control technology in order to realize passive load(ing) point, for aircaft configuration intensityIn process of the test, the mutual switching of multi-channel output signal, reaches test necessary requirement, and similar after beingProblem provides good technical support.
The invention provides a kind of vertical sensor output signal switch controller of false wheel of having led, mainly comprise:
Relay, comprises two inputs and an output, between first input end and output, arrangesThere is normally opened contact, between the second input and output, be provided with normally-closed contact;
Control module, for controlling the conversion between described normally opened contact and described normally-closed contact;
The first input signal, for monitoring sensor signal, connects described first input end;
The second input signal, is to have led the vertical sensor signal of false wheel, connects described the second input.
Preferably, described control module comprise power supply and be connected on described power supply and described relay betweenControl signal input, when described control signal input has signal when input, described power supply with described in continueElectrical equipment is communicated with, otherwise disconnects.
First it should be noted that, as shown in Figure 2, this relay 2 comprises three to the relay that the present invention adoptsGroup contact, 3,6,9 are respectively the common port of three groups of contacts, wherein, C3---C2, C6---C5, C9---C10Be three groups of normally opened contacts; C3---C4, C6---C7, C9---C8 is three groups of normally opened contacts. Standby at oneSelect in embodiment, also can be set to four groups of contacts, such as selecting HH54P relay.
Be understandable that the relay in main vertical sensor output signal switch controller of false wheel of the present inventionDevice can be also other signal switching apparatus, and as shown in Figure 1, it only need to be in input signal 1 and inputBetween signal 2, select one as output, this is because in the prior art, only plays false wheel by masterVertical sensor signal is as control, such as only having input signal 2, when its value of feedback and theoretical value differ veryWhen large, need to carry out ACTIVE CONTROL by supervision sensor signal, therefore, the invention provides another road input,Be provided with and monitor that sensor, as input signal 1, like this, utilizes simple circuit, a small amount of element,Can solve the problem that the input signal between multichannel is switched, effectively ensure that test loads essenceDegree.
Refer again to Fig. 2, in the present embodiment, first of the socket cut-in relay 2 of supervision sensor signalInput 1, i.e. C2, C5, C10 position, has led false socket cut-in relay of taking turns vertical sensor signalThe second input 4 of 2, i.e. C4, C7, C8 position, the output of the socket cut-in relay 2 of output signalEnd 3, i.e. C3, C6, C9 position, C1 and the C11 position of the socket cut-in relay of power supply 8, andBetween power supply 8 and relay 2, be parallel with control signal input 6, carry out on/off as switchControl, be understandable that the preferred 24V power supply of the present embodiment.
In addition, the present embodiment has also added indicator lamp in control module, at power supply 8 and relay 2Between be parallel with and switch display lamp 5 and power on light 7, power on light 7 is directly communicated with power supply 8,All the time in lighting lamp state, switch between display lamp 5 and power supply 8 and separate by control signal input 6,While only having control signal input 6 to have signal input, just can light.
Therefore, adopt after foregoing circuit connected mode, in the time of test pressurization, the power on light of this controller7 will light, and at this moment, if when control inputs signal is " 1 ", 24V power supply is relay power supply, relayOutput signal is input signal 1, switches display lamp 5 simultaneously and forms loop with 24V power supply, switches display lamp5 light; When control inputs signal is " 0 ", 24V power supply is not to relay power supply, relay output signalFor input signal 2, switch display lamp 5 and go out. According to test needs, can increase again a relay, defeatedEntering signal increases two-way, and output signal can increase by a road again, by that analogy.
It should be noted that in addition, in the present invention, the described signal of carrying to control signal input is certainlyDynamic control signal, plays false wheel vertical load spectrum by described master and controls.
For carrying out smoothly of guarantee test, multichannel input signal switch controller series connection Access Control is returnedLu Zhong. Need in control system, set the time of conversion according to test, then be exported by the numeral of control systemControl the break-make of 24V power supply signal, thereby realize the selection of relay to output signal, Field Force can be bySwitch display lamp and can directly watch the exporting of input signal channel on output Shi Na road.
The advantage or the good effect that compared with prior art have are as follows:
A) utilize simple circuit, a small amount of element, makes in engineering, and this equipment can in time to how logicalInput signal between road switches, and has effectively ensured test loading accuracy;
B) device is simple, is easy to install; Show and understand, be convenient to check;
C) processing technology is simple, changes easy, with low cost;
D) checkout gear does not affect the performance of existing system.
Main vertical sensor output signal switch controller of false wheel of the present invention, increases Liao Yi road and monitors sensorThe passive load(ing) point active control technology of signal input, solved owing to lead vacation and taken turns vertical sensor feedbackLittle more a lot of and cause exporting inaccurate defect than theoretical value. Mode by relay is to two-way input signalSelect input, more convenient, and the control signal of its control relay is automatic control information,Determined by loading spectrum, can facilitate to such an extent that reach this object by programming.
Finally it is to be noted: above embodiment is only in order to technical scheme of the present invention to be described, but not rightIts restriction. Although the present invention is had been described in detail with reference to previous embodiment, the common skill of this areaArt personnel are to be understood that: its technical scheme that still can record aforementioned each embodiment is modified,Or part technical characterictic is wherein equal to replacement; And these amendments or replacement do not make correspondingThe essence of technical scheme departs from the spirit and scope of various embodiments of the present invention technical scheme.
