Embodiment
Describe the preferred embodiments of the present invention in detail below in conjunction with accompanying drawing.
Embodiment one
The present invention has disclosed the number percent that a kind of indicator fault diagnosis system can detect the white lamp luminous point of indicator fault, submits to alert data to require the maintainer to safeguard replacing when it reaches certain threshold value.White lamp is made up of a lot of small lamp bulbs, in circuit design, the present invention is designed to the triplets series connection with it, and then many groups are in parallel, so its total current of passing through is subjected to the influence of lamp pearl quantity, the circuit at its place will no longer include electric current and pass through after the lamp pearl fault, and corresponding total current also reduces thereupon.Around this principle, our fault diagnosis module just can pass through the analytical sampling data, and the out of order lamp pearl of approximate calculating accounts for the number percent of total lamp pearl quantity, thereby reaches the purpose that fault number percent is accurately reported to the police.
Particularly, see also Fig. 1, described indicator comprises pilot lamp 20, and pilot lamp 20 comprises some groups of lamp pearls.Every group of lamp pearl comprises a lamp pearl or a plurality of lamp pearl that is cascaded, and each organizes the parallel connection of lamp pearl.
Described fault diagnosis system comprises the pilot lamp diagnostic module, can be used for judging the fault whether pilot lamp 20 of indicator exists needs to report to the police; Described fault diagnosis system comprises: detecting unit 11, fault analysis unit 12.
Detecting unit 11 is in order to detect the current/voltage of described indicator pilot lamp.
In the present embodiment, the resistance of every group of lamp pearl is identical in the pilot lamp 20.Each connects a resistance r after organizing the parallel connection of lamp pearl, and described detecting unit detects the voltage U at resistance r two ends when using; Obtain simultaneously and respectively organize the voltage U of lamp pearl when all intact
0Trouble light pearl group percentages is (U
0-U)/U
0
As shown in Figure 3, white lamp is made up of a lot of small lamp bulbs, and in circuit design, we are designed to the triplets series connection with it, and then many groups are in parallel.We know according to circuit knowledge, and the voltage at its circuit two ends of parallel circuit equates, simultaneously because the configuration of every street lamp pearl is identical, so the current i on its each road equates the total current I that it passes through
Just often=i * n (wherein n is the total quantity of parallel circuit).This shows that the size of total current I is subjected to lamp pearl number affects, the circuit at its place will no longer include electric current and pass through after the lamp pearl fault, and corresponding total current also reduces thereupon, suppose to have m cluster of lamps, ornamental pearl fault, at this moment total current I
During fault=i * (n-m), so just be easy to obtain: fault percentages=(I
Just often-I
During fault)/I
Just often
In the use of reality, general be difficult to directly electric current be sampled obtain its numerical value, so present embodiment adopts the mode at a small resistance of total current place serial connection, the magnitude of voltage at resistance two ends is sampled, thereby try to achieve the size of total current indirectly.As shown in Figure 4, the value with U represents small resistance two ends sampled voltage then can obtain total current I
Just often=U
Just often/ r, I
During fault=U
During fault/ r asks the formula of fault number percent with these two formula substitution preambles, then can obtain: fault percentages=(U
Just often-U
During fault)/U
Just often
According to the above principle, fault diagnosis module just can pass through analytical sampling gained voltage data, and the out of order lamp pearl of approximate calculating accounts for the number percent of total lamp pearl quantity, thereby reaches the purpose that white lamp failure number percent is reported to the police.
In addition, described fault diagnosis system can also be carried out analysis and judgement to the sampled data that signal sample circuit is submitted to, whether the identification display driver circuit exists unusually, and if any unusually then this abnormal data being submitted to the communication processing module, being packed by it encapsulates and send.
Such as its display driver employing of digital viewing area is the mode of dynamic scan, any one constantly all has only one digit number sign indicating number position to be scanned the circuit gating, that is to say that any time has only the pin of a figure case to have electric current to pass through, fault diagnosis system judges whether an above pin has electric current whether to have fault by the driving circuit that just can know digital viewing area as long as the sampled data that signal sample circuit is submitted to is analyzed at any time so.
Its display driver of digital viewing area adopts is that (with Fig. 5 is example for the mode of dynamic scan, to be exactly driving circuit light in Fig. 5 bit digital one with the very short time interval to so-called dynamic scan successively, be that certain is carved with when specific and has only one-bit digital to be lighted, when such time interval is enough short, because the eye storage characteristic of human eye, will can not differentiate the on and off of figure case, seem similarly to be that three figure cases are put light yellow simultaneously), any one constantly all has only one digit number sign indicating number position to be scanned the circuit gating, that is to say that any time has only the pin of a figure case to have electric current to pass through.
Sampling with white indicating light is similar, in the use of reality, general very difficult directly electric current the sampling obtained its numerical value, and in using, this only need know whether that electric current passes through, do not need to know its concrete numerical value fully, therefore present embodiment has designed a voltage sample change-over circuit, and it can be Transistor-Transistor Logic level (being expressed as logical and disconnected two states) with the CMOS level conversion that samples, and so only need make judgement to the Transistor-Transistor Logic level that obtains and get final product.
