In order to further understand feature of the present invention and technology contents, refer to following detailed description for the present invention and accompanying drawing, but accompanying drawing only provides reference and explanation use, is not used for being limited the present invention.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, by the specific embodiment of the present invention describe in detail, will make technical scheme of the present invention and other beneficial effect apparent.
In accompanying drawing,
Fig. 1 is the circuit diagram of the circuit of automatic detection power interface of the present invention;
Fig. 2 is the process flow diagram of the method for automatic detection safe grating power interface of the present invention.
Embodiment
For further setting forth the technological means and effect thereof that the present invention takes, be described in detail below in conjunction with the preferred embodiments of the present invention and accompanying drawing thereof.
Refer to Fig. 1, first the present invention provides a kind of circuit of automatic detection power interface, comprising: often open push button SB1, normally opened contact KA1, auxiliary reclay coil KA and pilot lamp HL1.
The described push button SB1 and auxiliary reclay coil KA that often opens is series between the first connection terminal 1 and the second connection terminal 2, and described normally opened contact KA1 and pilot lamp HL1 is series between the first connection terminal 1 and the second connection terminal 2; One wire L connects described auxiliary reclay coil KA and normally opened contact KA1, and makes described auxiliary reclay coil KA in parallel with pilot lamp HL1.
First, second connection terminal 1,2 described is respectively used to the high level interface end and the low level interface end that connect power interface to be detected, and wherein, the first connection terminal 1 is for connecting the high level interface end of power interface to be detected; Second connection terminal 2 is for connecting the low level interface end of power interface to be detected.Think that the power interface that the safe grating in automated storage and retrieval system is powered is example, described high level interface end and low level interface end are respectively DC24V and hold and hold with 0V.
Further, described auxiliary reclay coil KA and pilot lamp HL1 forms the auxiliary reclay of DC24V tape light, and the available model of auxiliary reclay of described DC24V tape light is as Japanese fuji HH52P-L/DC24V.
Refer to Fig. 2, composition graphs 1, on the basis of the circuit of above-mentioned automatic detection power interface, the present invention also provides a kind of method of automatic detection safe grating power interface, comprises the steps:
Step 1, provide the circuit of an above-mentioned automatic detection safe grating power interface as shown in Figure 1, herein no longer repeated description.
Step 2, occur abnormal when certain safe grating; the safe grating power interface corresponding with it is doubtful to go wrong; automated storage and retrieval system prompting " safe grating mistake " when shutting down; this safe grating is transferred to standby power supply interface, first, second connection terminal 1,2 of the circuit of described automatic detection safe grating power interface is connected respectively high level interface end and the low level interface end of the doubtful safe grating power interface gone wrong.
Step 3, press and describedly often open after push button SB1 makes it closed, then unclamp and make this often open push button SB1 to automatically reset.
If described pilot lamp HL1 is always bright, then judge that the described doubtful safe grating power interface gone wrong is normal.In such cases, this course of work automatically detecting safe grating power interface circuit is: press the described push button SB1 that often opens when making it closed, described auxiliary reclay coil KA and power supply are connected, and obtain electric self-locking, normally opened contact KA1 is closed, and described pilot lamp HL1 is bright; Unclamp and describedly often open after push button SB1 makes it automatically reset, described auxiliary reclay coil KA still forms loop by closed normally opened contact KA1 and power supply, make auxiliary reclay coil KA keep self-locking state always, described pilot lamp HL1 is always bright, thus can always bright accurately to determine the described doubtful safe grating power interface gone wrong normal according to described pilot lamp HL1.
If described pilot lamp HL1 goes out always or first bright after go out, then judge that the described doubtful safe grating power interface gone wrong is abnormal.
Being gone out by described pilot lamp HL1 always, to determine the described doubtful safe grating power interface that goes wrong abnormal, as in the situations such as open circuit, this course of work automatically detecting safe grating power interface circuit is: press the described push button SB1 that often opens when making it closed, if safe grating power interface is in the OFF state of open circuit, described auxiliary reclay coil KA will can not self-locking because obtaining externally fed, normally opened contact KA1 disconnects, and pilot lamp HL1 goes out; Unclamp and describedly often open after push button SB1 makes it automatically reset, described pilot lamp HL1 goes out always.After this, even if described safe grating power interface recovers the ON state of normal power-up, because the described push button SB1 that often opens is reset to off-state, described normally opened contact KA1 is also in off-state, described auxiliary reclay KA cannot with power supply connect cannot obtain electric, described pilot lamp HL1 can not be automatically bright again, thus can go out according to described pilot lamp HL1 that accurately to determine the described doubtful safe grating power interface that goes wrong abnormal always.
Go out after first bright by described pilot lamp HL1 and judge that the described doubtful safe grating power interface gone wrong is abnormal, as in the situations such as loose contact, the described doubtful safe grating power interface gone wrong is in the state of ON-OFF-ON, this course of work automatically detecting safe grating power interface circuit is: press the described push button SB1 that often opens when making it closed, described auxiliary reclay coil KA and power supply are connected, obtain electric self-locking, make normally opened contact KA1 of short duration closed, described pilot lamp HL1 is first bright; Unclamping the described push button SB1 that often opens makes it automatically reset to off-state, and pilot lamp HL1 keeps bright state because of the KA self-locking of auxiliary reclay coil; Subsequently, because the loose contact of safe grating power interface, be OFF state by ON state transfer, described auxiliary reclay coil KA and power supply disconnect, and then auxiliary reclay coil KA dead electricity removes self-locking, and normally opened contact KA1 disconnects, and pilot lamp HL1 goes out.After this, even if described safe grating power interface recovers normal ON state, because the described push button SB1 that often opens is reset to off-state, described normally opened contact KA1 is also in off-state, described auxiliary reclay KA cannot connect with power supply and cannot obtain electric, and described pilot lamp HL1 can not be automatically bright again.That is, again press operating personnel and describedly often open before push button SB1 makes normally opened contact KA1 closed, described pilot lamp HL1 will keep the state of going out.Thus can first bright according to described pilot lamp HL1 after go out that accurately to determine the described doubtful safe grating power interface gone wrong abnormal.
In sum, the circuit of automatic detection power interface of the present invention and the method for detection safe grating power interface, can accurately judge whether the power interface of safe grating goes wrong according to bright, the state of going out of pilot lamp in testing circuit, simple and convenient, contribute to the reason accurately judging safe grating exception, promote fault handling efficiency.
The above, for the person of ordinary skill of the art, can make other various corresponding change and distortion according to technical scheme of the present invention and technical conceive, and all these change and be out of shape the protection domain that all should belong to the claims in the present invention.
