Description
Technical field
Isolate memory type thunder and lightning counter but the utility model discloses a kind of photoelectricity, belong to thunder and lightning signals collecting field.
Background technology
In the lightning protection field, use traditional SPD to protect distribution, signal system far can not satisfy people's requirement according to GB50057, GB50343.
Find by retrieval, the thunder and lightning counting technology uses LC, triode, transformer formation transformer feedback formula oscillator that electric capacity is charged at present, and the light on and off of the pilot lamp in the dependence charging indication show whether be struck by lightning, perhaps utilize wireless sensing module to realize the distance reception data, under electromagnetic field of high frequency environment around the thunderbolt passage, wireless telecommunications are subject to disturb, and receiving terminal misoperation can occur, transmit weak points such as data are inaccurate.
Therefore develop a kind of being suitable for and be used, and the thunder and lightning counting appliance of record that can be safe and reliable and demonstration thunder and lightning time of origin and number of times there is very big practical application meaning with traditional SPD.
The utility model content
The technical vulnerability of aspects such as present thunder and lightning counter safe reliability is low in order to solve for the utility model, unmanned plane interactive interface, nothing storage, but provide a kind of photoelectricity to isolate memory type thunder and lightning counter.This thunder and lightning counter is suitable to be installed in the multifunctional lightning protection case or to cooperate lightning-protection module to be installed in to show and remember in the power supply panel box exact date that SPD is moved because of being struck by lightning and time (being accurate to second) and the number of times (automatically reseting after can writing down 99 times) that moves.Can utilize this thunder and lightning counter to analyze the frequency, time that the infield attacks by thunder and lightning waits and formulates concrete protectiving scheme.
The utility model is adopted following technical scheme by its technical matters of solution:
But a kind of photoelectricity is isolated memory type thunder and lightning counter, comprises supply module, single chip processing module, signal acquisition module, digital display module, reservoir and button; Supply module is used for providing stable direct current supply to single chip processing module; Single chip processing module is sent digital display module after being used to gather thunder and lightning signal, processing; Signal acquisition module is used for transmitting signal to single chip processing module; The numeral display module is used for operation, the data of display button; Storer is used to store data; Button is used to regulate and control storer; Signal acquisition module, single chip processing module and digital display module are linked in sequence, and supply module also is connected with single chip processing module, and reservoir is connected with single chip processing module is two-way respectively with button.
Described supply module comprises transformer, rectifier bridge and electric capacity, and transformer becomes alternating current about 7V with the 220V voltage transitions, gives the power supply of single-chip microcomputer liquid crystal by rectifier bridge and capacitor filtering with the direct current that the alternating current of 5V converts to about 5V.
Described signal acquisition module is linked in sequence by mutual inductor, current rectifying and wave filtering circuit and photoelectricity coupled circuit and forms.
The beneficial effects of the utility model are as follows:
1, adopt the supply module of isolating, and this module is protected, stability is high.
2, the device safe and reliable, because of the error count possibility that misoperation causes minimum.
3, thunder and lightning and weak current part are formed secondary isolation by coil, optocoupler, make single-chip microcomputer drop to minimum because of the excessive possibility that wrecks of the thunder and lightning on the circuit.
4, adopt LCD to show, designed friendly man-machine interface, make things convenient for the user to check, delete, store data.

Embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is described in further detail:
As shown in Figure 1, signal acquisition module is linked in sequence by mutual inductor, current rectifying and wave filtering circuit and photoelectricity coupled circuit and forms.Current rectifying and wave filtering circuit comprises rectifier bridge and electric capacity.The pulse voltage signal of mutual inductor induction produces the external interrupt that pulse signal is given single-chip microcomputer by optic coupling element at first by rectifier bridge and electric capacity rectifying and wave-filtering, realizes the collecting part of thunder and lightning signal.Select for use the mutual inductor (but self manufacture) of different sizes that lightening pulse is changed into weak electric signal according to the size that circuit is attacked by thunder and lightning may.
As shown in Figure 2, realize operations such as the reading of data, modification by three buttons and a storer (24c256); Realize the demonstration of data by LCD (12864).As SPD during because of thunderbolt conducting leakage current, can be on the SPD ground wire by the lightning current more than 90%, therefore utilize a mutual inductor (adjustable) that lightning current signals is changed into voltage pulse signal, and by an optocoupler, isolate issuable pulse high level, change into and give single-chip microcomputer less than the level of 5V and carry out computing; Time of coming real time record single-chip microcomputer received pulse by the DS12C887 clock chip, and number of times and time shown by 12864 liquid crystal displays, and can operate this system, carry out the calling of data, delete, operation such as demonstration by four buttons.
As shown in Figure 3, but a kind of photoelectricity is isolated memory type thunder and lightning counter, comprises supply module, single chip processing module, signal acquisition module, digital display module, reservoir and button; Supply module is used for providing stable direct current supply to single chip processing module; Single chip processing module is sent digital display module after being used to gather thunder and lightning signal, processing; Signal acquisition module is used for transmitting signal to single chip processing module; The numeral display module is used for operation, the data of display button; Storer is used to store data; Button is used to regulate and control storer; Signal acquisition module, single chip processing module and digital display module are linked in sequence, and supply module also is connected with single chip processing module, and reservoir is connected with single chip processing module is two-way respectively with button.
Described supply module comprises transformer, rectifier bridge and electric capacity, and transformer becomes alternating current about 7V with the 220V voltage transitions, gives power supplies such as single-chip microcomputer liquid crystal by rectifier bridge and capacitor filtering with the direct current that the alternating current of 5V converts to about 5V.
