Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 1, Fig. 1 is the structural representation of the utility model high pressure alarm set, and is as shown in Figure 1; It is installed on the gloves inside that operation is used, and the purpose of doing like this is where hi-line shaft tower maintainer is no matter climb to; As long as the place that hand touches; Near just can understanding whether the electrification in high voltage object is arranged, if detect the safe voltage that the voltage of electrified body is higher than human body, this high pressure alarm set will send alerting signal and point out at once.Said device comprises pre-process circuit 1, AD converter 2, microprocessor 3 and the battery 6 that is connected with microprocessor 3 respectively, hummer 4 and a plurality of LED lamp 5 that connects successively.
The effect of brief description various piece:
Pre-process circuit 1 is used for electromagnetic induction signal is carried out pre-service.Please combine to consult Fig. 2; Fig. 2 is the circuit diagram of pre-process circuit in the utility model high pressure alarm set; As shown in Figure 2; Said pre-process circuit specifically comprises inductive coil L, operational amplifier U1, resistance R 1, diode D1, diode D2, diode D3 and capacitor C 1, and wherein, first end of operational amplifier U1 is connected with the anode of diode D3 and an end of resistance R 1 respectively; The negative electrode of diode D3 is connected with said AD converter with an end of capacitor C 1 respectively, the other end ground connection of capacitor C 1; Second end of operational amplifier U1 is connected with the other end of resistance R 1, the end of inductive coil L, the negative electrode of diode D1 and the anode of diode D2 respectively; The 3rd end of operational amplifier U1 is connected with the other end of inductive coil L, the anode of diode D1 and the negative electrode of diode D2 respectively; The 4th end of operational amplifier U1 is connected with GND; The five terminal of operational amplifier U1 is connected with anode.In the present embodiment, inductive coil L produces induction current during near the alternating electromagnetic field environment, and this induction current at first tentatively amplifies through operational amplifier U1; And, prevent that via diode D1 and diode D2 overtension from burning operational amplifier U1 through calculating the adjusting magnification ratio as degenerative resistance R 1, carry out rectification through diode D3 again; Because the unidirectional conducting effect of diode D3 has been a unidirectional voltage via capacitor C 1, the effect of capacitor C 1 is filtering; At last, obtain stable voltage signal, so that this voltage signal is inserted AD converter at the OUT delivery outlet; The numerical value that microcontroller is exported AD converter is analyzed, and repeats no more at this.
Should be noted that; Said inductive coil L is made up of the thin copper wire coiling, and does not contain magnetic core in the middle of the coil of this inductive coil L, in addition; Because employed coil is soft and be rich in toughness; Present embodiment is fixed in the palm part of gloves with this inductive coil L, preferably is installed on the palm back side, does not like this influence the comfort level of gloves.
