Abstract
The utility model discloses a color changing light pillar indication alarm device. A casing of the device is provided with a color changing light pillar circuit board which is composed of two rows of LED tube cores with different colors, and a purpose-made grating face board, and the poles of the two rows of tube cores share one cathode or one anode. Through the arranged drive circuit, the utility model can individually control the LED tube cores with different colors within the set value range, that is to say, the light pillars with different colors can be displayed on the purpose-made grating face board according to the set range value, thereby, the purpose of alarm is obtained.
Description
The utility model belongs to the technology of instrument and meter field.
Alarm is the important instrument in the industrial control process.Traditional warning indicating instrument generally is divided into two big classes, and a class is the moving-coil pointer instrument, and another kind of is the light beam alarming instrument.The moving-coil pointer instrument adopts mechanical structure, and dependence is stirred pointer and come the regulation alarm range.This accuracy of instrument is lower, and can't realize distant surveillance, so eliminated gradually.The light beam alarming instrument generally adds special bright spot on light beam, perhaps adopt pilot lamp to glimmer and indicate warning.Since to bear higher curtage when adopting special bright spot or pilot lamp flicker indication, be easy to cause the early stage depletion of bright spot, thereby serviceable life is shorter.
The present invention is intended to overcome the problems referred to above, provides a kind of long service life, the indication of reporting to the police is directly perceived and changeable colour light band alarm indicator accurately.
The technical solution of the utility model is: according to green, yellow, the red three kinds of different colours of industrial controlling indicate respectively normally, the requirement of early warning, warning, designed by the changeable colour beam circuit board formed of LED tube cores of two row's different colours and special original screen panel, two comb cores one are cloudy extremely altogether or positive altogether.By set driving circuit, the LED tube core of the different colours in the range of set value is controlled respectively, like this, and can be on special original screen panel, by demonstrating the light beam of different color in the numerical range that sets, thereby reach the purpose of warning.
Through the utility model novel structure after the above-mentioned design, the indication of reporting to the police is directly perceived, accurately, it can not only make the operator accurately understand, grasp in good time situation in the industrial control process, and can play the effect of early warning to the operator, help the operator and carry out preventive measure, stop the generation of accident.
Concrete structure of the present utility model is as shown in drawings:
Fig. 1 is a contour structures synoptic diagram of the present utility model
Fig. 2 is the cut-away view of the utility model light beam case
Fig. 3 is the theory diagram of the utility model driving circuit
Below in conjunction with accompanying drawing specific embodiments of the present utility model is elaborated:
The changeable colour light band alarm indicator contains a casing 1, in casing 1, is provided with driving circuit.On casing 1, be provided with light beam display panel 2, on panel 2, be provided with changeable colour beam circuit board 3 and grating cover plate 4.On changeable colour beam circuit board 3, LED tube core 5, one rows that are provided with two row's different colours are the red LED tube core, and another is arranged and is the green LED tube core, and two comb cores 5 one are cloudy extremely altogether or positive altogether.On grating cover plate 4, be provided with grating 6, the width of grating 6 is 3.6～5mm, grating 6 is 3--4.0mm with the spacing of beam circuit board 3.
Being arranged at driving circuit in the casing 1 contains a signal converter, two and sets comparer and two drivers and two setting values.Signal converter is transformed into corresponding normal voltage signal with the signal voltage Vi or the marking current Ii of input.Setting comparer I is connected with red LED tube core on controlling and driving R driver and the beam circuit board; Setting comparer II is connected with green LED tube core on controlling and driving G driver and the beam circuit board.Setting value 1 is for to obtain and the corresponding voltage of early warning value from voltage stabilizing reference power supply dividing potential drop.Setting value 2 is for to obtain and the corresponding voltage of alarming value from voltage stabilizing reference power supply dividing potential drop.
Working method of the present utility model is: input voltage signal Vi or current signal Ii through signal converter outputting standard signal, compare this standard signal and setting value.Just often, set comparer II output high level, make the green LED tube core on the G driver conducting beam circuit board show that the expression system is in normal condition, the light beam luminous zone shows green.When input signal is higher than (or being lower than) setting value 1, set comparer I output high level, the red LED tube core on the R driver conducting beam circuit board is shown.At this moment, red, the green LED tube core of two rows is lighted simultaneously, causes that colourity changes, and the luminous zone of light beam shows orange-yellow, and the expression system enters alert status, and relay signal output simultaneously reminds the staff to note, performs corresponding preliminary work.
When input voltage signal Vi or current signal Ii when the standard signal of signal converter output continues to be higher than (or being lower than) setting value 1, and when being higher than (or being lower than) setting value 2, then R driver conducting red LED tube core continues to show, simultaneously because setting value 2 output low levels are closed the G driver, the green LED tube core does not show, then the luminous zone of light beam shows red, the expression system enters alarm condition, relay signal is exported simultaneously, thereby has realized the light beam variable color indication warning under the different operating state.
