Abstract
The utility model discloses a kind of grip gear detection device, comprise wire harness (1) and control capsule (4), the test hole that wire harness is offered by control capsule side is connected with the inner structure of control capsule, also comprise gearshift display device (2), gear magnitude of voltage telltale (3) and circuit card (5), gearshift display device, gear magnitude of voltage telltale is all placed in the upper surface of control capsule, circuit card is placed in the inside of control capsule, be connected with wire harness, electronic component on circuit card comprises A and D converter, micro controller system and LED charactron, micro controller system input end is connected with A and D converter, mouth is connected with LED charactron, this device is by converting the scope of standard gear voltage to numerical value write-in program, numerical value in the number signal value read by micro controller system and program contrasts, and by LED numeral method at gearshift display device, on gear magnitude of voltage telltale, intuitively can see whether gear and magnitude of voltage mate, judge that whether grip is qualified.
Description
Technical field
The utility model relates to a kind of detecting device, specifically a kind of grip gear detection device.
Background technology
Adjustable potentiometer is common grip gear detector, its principle of work is the matching detection of gear and magnitude of voltage, the i.e. a certain gear magnitude of voltage that has it corresponding, but in actual use, because physical construction is in manufacture with install and inevitably there is error, even if just cause the grip of same batch also to there is certain difference, difference little and the use that can meet grip in range ability, but what difference was large just easily causes gear and magnitude of voltage not to mate, the judgement refueling or subtract oil made by controller according to this inaccurate magnitude of voltage, not only testing goal can not be reached, even also construction machinery and equipment can be damaged.
In the face of the problems referred to above, also attempt the detection carrying out grip gear by following two kinds of methods, but still there is obvious defect:
1) assemble after with the output voltage of each grade of multi-meter amount, see that output voltage is not or not in the scope of place gear.This method detects precisely, but operation is upper loaded down with trivial details, and each gear tests one time incessantly, and also higher to the requirement of multi-meter precision.
2) test is gone above the main frame directly receiving auxiliary products.This method is directly perceived, and testing result is very clear, but batch manufacturing can not take again client, and there is tested one by one.
Summary of the invention
The utility model provides a kind of grip gear detection device, effectively can detect that whether detection grip is qualified, and easy to operate, and accuracy is high.
For achieving the above object, this grip gear detection device, comprise wire harness and control capsule, the test hole that wire harness is offered by control capsule side is connected with the inner structure of control capsule, also comprise gearshift display device, gear magnitude of voltage telltale and circuit card, described gearshift display device, gear magnitude of voltage telltale is all placed in the upper surface of control capsule, described circuit card is placed in the inside of control capsule, and be connected with wire harness, electronic component on circuit card comprises A and D converter, micro controller system and LED charactron, the input end of micro controller system is connected with A and D converter, mouth is connected with LED charactron.
Further, also comprise buzzer phone, described buzzer phone is connected with the mouth of micro controller system.
Compared with existing installation, this grip gear detection device is by converting the scope of standard gear voltage to numerical value write-in program, numerical value in the number signal value read by micro controller system and program contrasts, and by LED numeral method on gearshift display device, gear magnitude of voltage telltale, can see whether gear and magnitude of voltage mate intuitively, judge that whether grip gear is qualified, overcome the defect that existing physical construction exists when detecting to a great extent, precision is high, and facilitates feasible; Buzzer phone is as another device of pointing out off-grade, and when the grip magnitude of voltage detected is not in gear bands, buzzer phone will be reported to the police, and the application of auditory tone cues further increases judging efficiency and the accuracy of operating personal.
Accompanying drawing explanation
Fig. 1 is the constructional drawing of this utility model;
Fig. 2 is circuit card fundamental diagram.
In figure: 1, wire harness, 2, gearshift display device, 3, gear magnitude of voltage telltale, 4, control capsule, 5, circuit card.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As illustrated in fig. 1 and 2, this grip gear detection device, comprise wire harness 1 and control capsule 4, the test hole that wire harness 1 is offered by control capsule 4 side is connected with the inner structure of control capsule 4, also comprise gearshift display device 2, gear magnitude of voltage telltale 3 and circuit card 5, described gearshift display device 2, gear magnitude of voltage telltale 3 is all placed in the upper surface of control capsule 4, described circuit card 5 is placed in the inside of control capsule 4, and be connected with wire harness 1, electronic component on circuit card 5 comprises A and D converter, micro controller system and LED charactron, the input end of micro controller system is connected with A and D converter, mouth is connected with LED charactron.
Further, this device also comprises buzzer phone, and described buzzer phone is connected with the mouth of micro controller system, when gear and magnitude of voltage do not mate, buzzer phone meeting alarm, causes the attention of operating personal, improves detection efficiency and the precision of inferior-quality grip further.
By wire harness 1 with grip to inserting, grip output voltage values, the magnitude of voltage collected is converted to digital signal by A and D converter, convert the scope of standard gear voltage to digital value and write-in program again, by micro controller system, the digital value in the external digital signal value read and program is contrasted.In gear bands, the gearshift display device 2 connected by LED charactron and gear magnitude of voltage telltale 3 normally display current gear and current voltage value; Not in gear bands, the gearshift display device 2 connected by LED charactron and gear magnitude of voltage telltale 3 show "--" and current voltage value, buzzer warning prompting simultaneously.
Claims (2)
1. a grip gear detection device, comprise wire harness (1) and control capsule (4), the test hole that wire harness (1) is offered by control capsule (4) side is connected with the inner structure of control capsule (4), it is characterized in that, also comprise gearshift display device (2), gear magnitude of voltage telltale (3) and circuit card (5), described gearshift display device (2), gear magnitude of voltage telltale (3) is all placed in the upper surface of control capsule (4), described circuit card (5) is placed in the inside of control capsule (4), be connected with wire harness (1), electronic component on circuit card (5) comprises A and D converter, micro controller system and LED charactron, the input end of micro controller system is connected with A and D converter, mouth is connected with LED charactron.
