Fig. 1 is the electronic lead seal device structured flowchart of measurement instrument in the embodiment of the present invention.
Fig. 2 is the electronic lead sealing method flow diagram of measurement instrument in the embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in Figure 1, the electronic lead seal device of the measurement instrument in the present embodiment, comprise the central processing unit 1 be arranged in measurement instrument housing, power supply 2, storer 3, photosensitive processing module 4 and communication module 5, also comprise the touch switch 6 being arranged on measurement instrument housing junction.Power supply 2, storer 3, photosensitive processing module 4, touch switch 6, communication module 5 are connected with central processing unit 1 respectively, and photosensitive processing module 4, touch switch 6 are also connected with power supply 2 respectively.
Central processing unit 1 is for the computing to various Detection Information.
Power supply 2 is for the power supply of central processing unit 1.Various different power supply 2 can be selected according to different demands in use, in the present embodiment, select battery to power.
Storer 3 is for storage data.
Photosensitive processing module 4 is for the treatment of the light change information in measurement instrument housing, and this photosensitive processing module 4 can select existing optical detection circuit, also directly can use by selective light dependent sensor finished product, selects light sensor in the present embodiment.Usually, be enclosed environment in normal measurement instrument housing, inside is in dark state, when cheating device is installed in measurement instrument, need to open measurement instrument housing, then extraneous light can enter in apparatus shell, and the photosensitive processing module 4 of housing can detect light change information, thus can find the orcible entry information of housing in the case.
Touch switch 6 can select closed type switch or open type switch, selects normally closed property to touch and open the light in the present embodiment.Touch switch 6 is arranged on measurement instrument housing junction, and under normal conditions, involutory housing extruding touch switch 6, then touch switch 6 is in normally open to measurement instrument housing.When measurement instrument housing is opened, touch switch 6 action is upspring, then touch switch 6 is in normally off.Thus the orcible entry information of housing also can be found according to the state change of trigger switch
Communication module 5 destroys information for transmitting lead sealing, can by the orcible entry information of housing by this communication module 5, i.e. the destruction information of lead sealing is sent on the server of supervision department, thus realizes the supervision to measurement instrument cheating.
As shown in Figure 2, the lead sealing method of the measurement instrument in the present embodiment, namely when measurement instrument housing is opened, touch switch 6 action, the on off state of touch switch 6 changes formation switch actuating signals, and in the present embodiment, touch switch 6 becomes normally off from normally open.Photosensitive processing module 4 detects that light change forms light sensation variable signal simultaneously.Now the switch actuating signals of touch switch 6, the light sensation variable signal of photosensitive processing module 4 or signal that both occur simultaneously all can turn-on powers 2, thus power supply 2 is powered for central processing unit 1.
Thereupon, central processing unit 1 works, central processing unit 1 receives the switch actuating signals of touch switch 6 and the light sensation variable signal of photosensitive processing module 4, and the light sensation variable signal of the switch actuating signals of touch switch 6 and photosensitive processing module 4 is stored in storer 3, thus formed housing open recorded information.When measurement instrument is energized use again, the recorded information of opening of housing is sent on the server of supervision department by communication module 5 by central processing unit 1, thus realizes the warning to cheating.
Photosensitive processing module 4 and touch switch 6 are used in the present embodiment, when can avoid installing separately touch switch 6 on the one hand, poly-talented lawless person dissects measurement instrument from interface position simultaneously, thus destroys the lead seal function of touch switch 6 from interface.On the other hand, can avoid lawless person in darkroom, disassemble the housing of measurement instrument, and photosensitive processing module 4 effectively can not play its lead seal function, but in Work Safety Office to disassemble difficulty also very large.The photosensitive processing module 4 of conbined usage and touch switch 6, can mutually make up respective shortcoming, when destroying touch switch 6 by disassembling interface, photosensitive processing module 4 can play its lead seal function, the housing disassembling measurement instrument in darkroom can trigger touch switch 6, so then makes this electronic lead sealing effect more reliable.
The electronic lead seal device of this measurement instrument and lead sealing method can be used in weighing instrument, also can be used in other measuring instruments, instrument, applied range.
