Deng.In one embodiment, the folding condition (that is to say switch tool state described below) of switch tool is included at switch
In closure state, switch are off, disconnecting link is in closure state and disconnecting link is off.Folding condition is typically used
Numeral 1 or numeral 0 are represented, for example, represent that switch is in closure state with 1, represent that switch is off, it is necessary to say with 0
Bright, the present invention makes restriction not to this, and folding condition can also be represented with other forms, such as metric form table
Show.
The mode that processor 101 obtains the folding condition of each switch tool to be simulated has many kinds.For example, such as Fig. 2
Shown, in one embodiment, the processor 101 is connected with host computer 300, can be on switch tool analogue means 100
Host computer interface is set, and processor 101 is connected by the host computer interface with host computer 300.Optionally, the host computer interface

Pass has two, then whole on off states have 00,01,10 and 11, and these switch tool states can be stored in forms such as forms
In host computer 300, when needing to be tested, host computer 300 by whole switch tool states of storage be spaced one by one transmission or
The switch tool state that person is all sent in processor 101, the form that 101 pairs of processor is received is decoded, then
Decoded information is sent to first switch amount output circuit 102.The whole switch tool states to be tested can be used
Human-edited's form is realized, it would however also be possible to employ existing switching value combinatorial logic state implementation is given birth to automatically in the prior art
Into the present invention makes restriction not to this.
In another embodiment, processor 101 itself storage needs the folding condition for each switch tool simulated, respectively
The folding condition of individual switch tool can be with the storage of the forms such as form in the processor 101.The processor 101 is obtained from itself
Wait after the folding condition for each switch tool simulated, the folding condition of each switch tool of acquisition is decoded, and will
The folding condition of each decoded switch tool is sent to the first switch amount output circuit 102.Likewise, to be tested
Whole switch tool states can be realized using human-edited's form, it would however also be possible to employ existing switching value group in the prior art
Logical state implementation is automatically generated, and the present invention makes restriction not to this.
In addition, related operational order is also sent to the processor 101, the processor 101 by the host computer 300
Carried out according to the operational order after relevant treatment, response results are returned into the host computer 300, wherein the operational order
Including enabled instruction and/or pair when instruction etc., result can for start whether it is successful and pair when whether successfully etc..Pass through
Host computer 300 carries out assigning for dependent instruction, you can test each switch tool folding condition for needing to test automatically.
Processor 101 sends the division state of related switch disconnecting link to first switch amount output circuit 102, for simulating reality
The folding condition of border related switch disconnecting link.First switch amount output circuit 102 is received after 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 is in closure
State or disconnecting link are in closure state (such as processor 101 exports numeral 1), the first switch amount output circuit 102 to
The second switch amount output circuit 103 exports high level, and the second switch amount output circuit 103 amplifies the high level
To the voltage and output matched with the equipment 200 to be tested；If switch is off or disconnecting link is off
(such as processor 101 export numeral 0), the first switch amount output circuit 102 is to the second switch amount output circuit 103
Low level 0V is exported, the voltage of the second switch amount output circuit output is low level 0V.It should be noted that the present invention is simultaneously
The concrete numerical value for the low pressure not exported to first switch amount output circuit 102 is limited.
In one embodiment, as shown in figure 3, the programmable switch tool analogue means realized can also include being connected to
Isolation circuit 104 between the first switch amount output circuit 102 and the second switch amount output circuit 103.By every

Shown, in one embodiment, the programmable switch tool analogue means realized is also defeated including being connected to the second switch amount
The toggle switch 105 gone out between circuit 103 and the equipment to be tested 200, the second switch amount output circuit 103 passes through institute
State the voltage swing of its output of the regulation of toggle switch 105.
If for example, actual control protective unit input voltage is 24V, second switch is adjusted by toggle switch 105
The high level for measuring the output of output circuit 103 is 24V；If actual control protective unit input voltage is 48V, opened by dial-up
It is 48V to close 105 high level for adjusting the output of second switch amount output circuit 103；If actual control protective unit input voltage
For 110V, then the high level for adjusting the output of second switch amount output circuit 103 by toggle switch 105 is 110V；If actual
Control protective unit input voltage is 220V, then the height of the output of second switch amount output circuit 103 is adjusted by toggle switch 105
Level is 220V.
Automatically the whole switch tool states to be tested can be enumerated on host computer, pass through institute of the embodiment of the present invention
The switch tool analogue means provided carries out the automatic imitation of each switch tool state, so as to realize to be tested
The automatic test of equipment, it is to avoid the poor efficiency manually tested, improves operating efficiency.Further, since the present invention is implemented
