Abstract
The utility model relates to a LCD warning metal detector that discolours in a poor light, including a CPU and rather than the LCD liquid crystal display, metal detection function block, power module and the warning subassembly that link to each other, CPU still be connected with the backlight of the different colours of a plurality of groups. The utility model discloses it shows that different colour screens are shaded the more use of convenience of customers in various different environment to survey the result according to the difference in the detection.
Description
Technical field
the utility model relates to metal detector field, particularly a kind of LCD backlight variable color warning metal detector.
Background technology
Metal detector can be applicable to multiple field, and militarily, metal detector can be used for detecting metallic mine; In security fields, the weapon and tool used in crime carried with or hide can be detected; In archaeology, the ancient tomb of burying metal can be detected, find gold, silver, treasures and jewels in ancient tomb and jewellery or other metallic articles; In engineering, can be used for Underground metal embedded object, such as pipeline, pipeline etc.; In ore prospecting, can be used to detect and find rusty gold particle; Industrial, can be used for on-line monitoring, as removed cotton, coal, the metal sundries etc. in food.Metal detector also can be used as the apparatus carrying out teenager's defence education and activity to popularize scientific knowledge, also to can yet be regarded as interesting games for play, particularly recent years, personal interest metalloid detector is popularized by American-European countries on a large scale, and metal detection activity is developed the part becoming outdoor exercises.
But existing metal detector all only has a kind of backlight, different result of detections all can only rely on the prompting such as text importing or loudspeaker, but sound decibel is limited exigent occasion be obviously not suitable for loudspeaker report to the police, if only rely on text importing prompting to need operating personnel to detect while note the display screen of detector, bring very big inconvenience to detection operations.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of LCD backlight variable color warning metal detector, backlight LED is arranged and adopts multiple color LED combination, according to different result of detection display different colours screen backlight in detection, can the use of more convenient user in various varying environment.
The utility model adopts following scheme to realize: a kind of LCD backlight variable color warning metal detector, comprises a CPU and coupled LCD liquid crystal display screen, metal detection function assembly, supply module and alarm assemblies; Described CPU is also connected with the backlight of some groups of different colours, lights a kind of colour backlight source when metal detector normally works, and when metal or warning or other situations being detected, correspondence lights different colours backlight.
Further, described backlight is LED backlight.
Further, described supply module comprises power supply switch circuit and coupled solar module and battery module.
Backlight LED arranges and adopts multiple color LED combination by the utility model, according to different result of detection display different colours screen backlight in detection, and can the use of more convenient user in various varying environment.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, present embodiments provide a kind of LCD backlight variable color warning metal detector, comprise a CPU and coupled LCD liquid crystal display screen, metal detection function assembly, supply module and alarm assemblies; Described CPU is also connected with the backlight of some groups of different colours, and for LCD screen is configured with 2 groups of backlight LEDs 1 and LED2 in Fig. 1, wherein LED1 is green LED backlight, and LED2 is red LED backlight.
In the present embodiment, described backlight is LED backlight.
Especially, in the present embodiment, described supply module comprises power supply switch circuit and coupled solar module and battery module, in the place having sunlight, solar cell automatic charging, entering the inferior place not having sunlight, preferentially use accumulator, when accumulator does not have electricity, conversion uses the solar cell charged.
Preferably, metal detection signal is transferred to CPU input end from the metal detection function assembly figure, and CPU lights according to testing result control LED1 green when metal not detected, and LED2 redness is extinguished; When metal being detected, control LED1 green is extinguished, and LED2 redness is lighted.
In sum, backlight LED arranges and adopts multiple color LED combination by the utility model, according to different result of detection display different colours screen backlight in detection, and can the use of more convenient user in various varying environment.
It is worth mentioning that, to these are only in the utility model embodiment a preferably embodiment.But the utility model is not limited to above-mentioned embodiment, all any equalizations done by the utility model scheme change and modify, and when the function produced does not exceed the scope of this programme, all belong to protection domain of the present utility model.
