Switch tool analogue means 200 is connected by netting twine or Serial Port Line with the host computer 100.
Processor 202 can use existing equipment realization in the prior art, in one embodiment, the processor
202 can be DSP (Digital Signal Processing, digital signal processor) or FPGA (Field-
Programmable Gate Array, field programmable gate array) etc..Processor 202 needs to obtain each switch to be simulated
With the folding condition (switch tool state i.e. described below or the folding condition of switch tool) of disconnecting link.The folding shape of switch
State includes switch and is off in closure state and switch, the folding condition of disconnecting link include disconnecting link be in closure state with
Disconnecting link is off.Folding condition is typically represented with numeral 1 or numeral 0, such as represents that switch is in closed form with 1
State, represent that switch is off, it is necessary to illustrate with 0, the utility model makes restriction not to this, and folding condition is also
It can be represented with other forms, such as metric form represents.
The mode that processor 202 obtains the folding condition of each switch tool to be simulated has many kinds.For example, at one
In embodiment, the processor 202 obtains the folding condition of each switch tool to be simulated from the host computer 100, to obtaining
The folding condition of each switch tool taken is decoded, and the folding condition of decoded each switch tool is sent into institute
State first switch amount output circuit 203.Host computer 100 stores the whole switch tool states to have been tested, for example, to be surveyed
The switch of examination has two, then the folding condition all switched has 00,01,10 and 11, and these switch tool states can be with form
It is stored in etc. form in host computer 100, when needing to be tested, host computer 100 is by whole switch tool states one of storage
One interval sends or is all sent to processor 202, and processor 202 enters to the switch tool state in the form that receives
Row decoding, is then sent to first switch amount output circuit 203 by decoded information.The whole switch tool shapes to be tested
State can use human-edited's form to realize, can also use existing switching value combinatorial logic state realization side in the prior art

Whole switch tool states human-edited's form can be used to realize, existing switching value group in the prior art can also be used
Logical state implementation automatically generates, and the utility model makes restriction not to this.
In addition, the operational order of correlation is also sent to the processor by the host computer 100 by host computer interface 201
202, after the processor 202 carries out relevant treatment according to the operational order, response results are returned into the host computer
100, wherein the operational order include enabled instruction and/or pair when instruction etc., result can be start whether it is successful with
And pair when whether successfully etc..Pass through host computer 100 and carry out dependent instruction and assign, you can automatically testing each needs that tests to open
Close the folding condition of disconnecting link.
Processor 202 sends the division state of related switch disconnecting link to first switch amount output circuit 203, for simulating reality
The folding condition of border related switch disconnecting link.After first switch amount output circuit 203 receives the folding condition of each switch tool,
Output and the one-to-one voltage of folding condition of each switch tool.For example, in one embodiment, if switch or disconnecting link
In closure state (such as processor 101 export numeral 1), the first switch amount output circuit 203 is to the second switch
Measure output circuit 204 export high level, the second switch amount output circuit 204 by the high level be amplified to it is described to be measured
Try the voltage that equipment 300 matches and output；If switch or disconnecting link are off (such as processor 101 exports numeral 0),
The first switch amount output circuit 203 exports low level 0V, the second switch to the second switch amount output circuit 204
It is low level 0V to measure the voltage that output circuit 204 exports.It should be noted that the utility model does not export to first switch amount
The concrete numerical value for the low pressure that circuit 203 exports is limited.

Level can be 24V/48V/110V/220V, low level 0V.It should be noted that the utility model is not to second switch
The concrete numerical value for the voltage that amount output circuit 204 amplifies makes restriction.
In conventional art, equipment 300 to be tested is the virtual unit realized by software, by different switch tools
Corresponding manual set is carried out, realizes the test to virtual unit, has area due to virtual unit or with actual physical unit
Not, therefore the scheme in conventional art can not the whole switch tool process of accurate simulation.Therefore, for the defect, in a reality
Apply in example, the equipment 300 to be tested is actual control protective unit；The second switch amount output circuit 204 with it is described
Control protective unit is connected, the voltage matches of its voltage exported and the control protective unit.Switch tool analogue means 200
It is directly connected to what is tested with actual physics device, thus it is more true, being capable of the whole switch tool process of accurate simulation.Need
It is noted that equipment to be tested 300 of the present utility model is not intended to limit then control protective unit, if desired for other devices
Tested, the utility model can also be other actual devices.
Second switch amount output circuit 204 is connected with the equipment to be tested of reality, due to electric needed for equipment 300 to be tested
Pressure is certain, and second switch amount output circuit 204 can export the voltage of a variety of numerical value, therefore is specifically being tested
When, related voltage can be exported, according to the needs of actual equipment to be tested for being matched with equipment 300 to be tested.Such as Fig. 2
Shown, in one embodiment, switch tool analogue means also includes being connected to the second switch amount output circuit 204 and institute
The toggle switch 206 between equipment 300 to be tested is stated, the second switch amount output circuit 204 passes through the toggle switch 206
Adjust the voltage swing of its output.
For example, if actual control protective unit input voltage is 24V, second switch is adjusted by toggle switch 206
It is 24V to measure the high level that output circuit 204 exports；If actual control protective unit input voltage is 48V, opened by dial-up
The high level for closing the output of 206 regulation second switch amount output circuit 204 is 48V；If actual control protective unit input voltage
Then it is 110V by the high level of the output of the regulation second switch amount of toggle switch 206 output circuit 204 for 110V；If actual
Control protective unit input voltage is 220V, then the height of the output of second switch amount output circuit 204 is adjusted by toggle switch 206
Level is 220V.
Automatically the whole switch tool states to be tested can be enumerated on host computer, are implemented by the utility model
