Abstract
The utility model discloses a simple module lightning stroke counter, and relates to the filed of lightning protection micro-electronic technology. Most of the traditional lightning stroke counters are double-module in width, can not be installed due to the original oversize structural dimension, and require alternate current for power supply, so that volume, cost, safety and stronger EMC (Electro Magnetic Compatibility) should be considered. The lightning stroke counter provided by the utility model is single-module in width, adopts the outline being a structure of 18mm, facilitates the engineering installation in more occasions due to the single-module dimension, and adopts battery for power supply and shielding display, thereby avoiding too much consideration for safety and EMC.
Description
Technical field
The utility model relates to lightning protection device and single-chip microcomputer microelectronics technology, relates in particular to a kind of monolithic processor controlled thunder and lightning counter.
Background technology
In recent years; The thunder and lightning disaster is the serious disaster in the China and even the whole world always, and the same with other most of disasteies, the mankind can not change its generation; Can only reduce its infringement through other defensive measure, so grown related industries such as lightning protection electronics and lightening protection engineering.Present lightning arrester is through Zinc-oxide piezoresistor mostly; Gas-discharge tube; The transient state diode comes lightning current is released, and each major company is also to through-current capacity, and very big effort has been made in the optimization of technical parameters such as residual voltage; Present lightning arrester all is through-flow with greatly, and low residual voltage is that target designs.
Because the waveform of lightning current comprises that peak value and wavelength all are indefinite, no matter is 8/20 or 10/350 model; It all is a kind of theoretical value; Add various devices continuous wearing out at the scene, accident still emerges in an endless stream, so the monitoring of thunder and lightning disaster just seems important.In various monitoring, the record of thunder and lightning number of times is a most basic a kind of pattern, and all big enterprises extensively dispose this function in the lightning protection box of oneself, and after accident took place, the thunder and lightning number of times can be used as effective foundation that accident responsibility is divided.In the present electric power and the project installation of lightning protection, all widely used is standardized module, all is the device with the normal width of 18mm*N.The benefit of bringing like this is: each module is conversion producer arbitrarily, because all products of each producer all satisfy the standard of 18mm*N, it only needs the wide guide rail of 35mm just can accomplish installation.Aspect the thunder and lightning counter, also there are a lot of producers to release the product of this modular, still great majority all are that the bimodulus piece is wide, i.e. the width of 36mm.Such size shows slightly excessive; If in the lightning protection box of a no counter module own, add this function again; Just can't install because of original physical dimension design problem probably, thereby largely must limit to counter module and sell as independent product.
The electronic type counter can be divided into segmentation liquid crystal counter and charactron counter again according to the difference of display device.Segmentation liquid crystal counter exploitation difficulty, cost are too for thunder and lightning producer; Therefore high most manufacturers all develop the thunder and lightning counter of digital tubular type, and for the such display mode of charactron, the problem that at first will consider is exactly a power supply.The electric current of charactron is a milliampere level, and it is far from being enough under the normal situation that shows of charactron, depending merely on battery, must introduce AC power, and will consider volume, cost, security, stronger problems such as Electro Magnetic Compatibility EMC after introducing AC power.
Summary of the invention
For said problem the utility model above solving provides a kind of single module thunder and lightning counter.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
A kind of single module thunder and lightning counter; Comprise control chip, charactron, sensor for countering and PCB printed board; It is characterized in that: the standard single mode piece with 18mm is wide is made external structure; Charactron adopts shielding to show, power supply adopts powered battery, by the interruption of sensor for countering or the interrupt enable control chip of button.
The demonstration of the utility model adopts double figures sign indicating number pipe to show.
The supplying cell of the utility model adopts 3V, volume to be not more than any battery of 51 x, 23 x 15mm.
The control chip of the utility model is the single-chip microcomputer of 3V, does not work at ordinary times, depends merely on the interruption of sensor for countering or the interruption of button and activates.
The utility model comprises one by key control, and is short in showing, long by zero clearing.
Effective effect:
One, adopts wide standard single mode piece thunder and lightning counter and the standardized module size of 18mm to be equal to, be convenient to install conversion, and impel counter module to sell as independent product.
Two, adopt shielding to show, can save a large amount of power consumptions.
Three, adopt powered battery, must not consider stronger problems such as Electro Magnetic Compatibility EMC.

Fig. 3 single module thunder and lightning counter workflow diagram.
Embodiment
To combine accompanying drawing and embodiment that the utility model is done further to describe below.
Embodiment one
A button is set, and control chip is in dormant state under the normality, not video data; Regularly show a period of time after pushing button, the length of time can be according to actual conditions and opinion, and the demonstration time is adjustable; Be generally about 5s; This button also has second function, promptly lets show the original state that resets to " 00 ", and two kinds of functions are distinguished through the time length of pressing.So, depend merely on battery and just can support the running that it is not less than 5 years.
Embodiment two
Aspect signals collecting, adopt traditional magnet ring socket mode, a lead and a magnet ring just can be made a sensor for countering, again with sensor sleeve on the PE of leakage current line, be very easy on the project installation.
Embodiment three
Single module thunder and lightning counter is installed on the lightning-protection module of the lightning current of need releasing, and on the ground wire like surge protector, initial counting electric current is 1kA (8/20 μ s).
Claims (5)
1. single module thunder and lightning counter; Comprise control chip, charactron, sensor for countering and PCB printed board; It is characterized in that: the standard single mode piece with 18mm is wide is made external structure; The charactron shielding shows, adopts powered battery, depends merely on the interruption of sensor for countering or the interruption of button and activates control chip.
