As shown in fig. 1 and 2, the rear ends of the front permanent magnet coils 41 and the front ends of the rear permanent magnet coils 102 have opposite polarities and have identical outer diameters. The control circuit comprises resistors R1 and R2, a capacitor C1, an NPN triode Q1, a relay K1 and a mercury switch W which are connected through circuit board wiring, wherein the positive power input end and the control power input end of the relay K1 are connected with one end of the mercury switch W, the other end of the mercury switch W is connected with one end of a first resistor R1, the other end of the first resistor R1 is connected with one end of a second resistor R2 and the positive electrode of the capacitor C1, the other end of the second resistor R2 is connected with the base electrode of the NPN triode Q1, the collector electrode of the NPN triode Q1 is connected with the negative power input end of the relay K1, and the emitter electrode of the NPN triode Q1 is connected with the negative electrode of the capacitor C1. The mercury switch W is a universal mercury switch, the mercury switch W is vertically welded on the circuit board, the mercury liquid level of the mercury switch W is positioned at the lower end in the shell of the mercury switch, two contacts are positioned at the upper end (the two contacts are spaced by 2 cm from the mercury liquid level), when a person runs normally, the mercury liquid level does not submerge the two contacts, and after the person falls down, the mercury liquid level contacts and submerges the two contacts. The pin 2 of the A1 negative power input end of the short message module is connected with the pin 3 of one of the signal input ends through a wire. The detection circuit comprises an adjustable resistor RP and a resistor R3 which are connected through circuit board wiring, and one end of the resistor R3 is connected with one end of the adjustable resistor RP.

Fig. 1 and 2 show that the novel head-wearing infrared thermal imaging glasses body has all other functions of common head-wearing infrared thermal imaging glasses, and a wearer can clearly see surrounding things under night conditions after wearing the glasses on the head; specifically, the head-wearing type infrared thermal imaging glasses body detects infrared specific wave band signals of object thermal radiation by using a photoelectric technology, converts the signals into images and figures which can be distinguished by human vision, is particularly applied to the fields of military and the like, and can further improve the night combat capability of the army. In the utility model, when the wearer needs to check the distance between the wearer and the target object (the power switch S1 is turned on), the rear end of the shell 4 and the lens barrel at the left end are attracted together through the front magnet ring 41 and the rear magnet ring 102 (the left eye of the wearer can see the distance data displayed by the display screen V; when the distance data is not needed to be checked, the shell is attracted together through the front magnet ring 41 and the attracting piece 103, and the eyes of the wearer can watch things). When the distance between the laser ranging module A2 and the target object is measured, the probe of the laser ranging module A2 is aligned with the target object, when the distance between the laser ranging module A2 and the target object is relatively far, the voltage signal output by the 3 feet of the signal output end is relatively large, when the distance between the laser ranging module A2 and the target object is relatively close, the voltage signal output by the 3 feet of the signal output end is relatively small, the voltage signal enters the positive power supply input end of the voltage display screen V after being divided by the adjustable resistor RP and the resistor R3, thus, when the distance between the wearer and the target object is relatively far, the number of the representing distance displayed by the voltage display screen V is relatively large (for example, the displayed number is 1.00V, then the distance between the representing distance and the object or the person is 100 m, and the displayed number is 0.25V, and the distance between the representing distance and the object or the person is 25 m), and when the distance between the wearer and the target object is relatively close, the number of the representing distance displayed by the voltage display screen V is relatively small. Through the above-mentioned, the utility model discloses just can conveniently observe the interval between self and specific article (including personnel).

As shown in fig. 1 and 2, when the wearer wears normally and does not fall to the ground, the mercury of the mercury switch W does not submerge the two contacts, so that the relay K1 does not get to be electrically attracted, and the short message module A1 does not get to be electrically operated to send a short message to a far-end related person. When a wearer falls to the ground accidentally, mercury of the mercury switch W can submerge the two contacts, so that the 12V power supply output by the storage battery G1 can be reduced in voltage by limiting through the resistor R1 to charge the capacitor C1, and in a period of time just started (for example, in 1 minute, the time is equal to 1.1 of the capacitance of the capacitor C1, the resistance value of the resistor R1 is equal to 1), when the capacitor C1 is not fully charged, the 12V power supply enters the NPN triode Q1 through limiting through the resistors R1 and R2 and reducing in voltage, the base electrode of the NPN triode Q1 is lower than 0.7V, the NPN triode Q1 cannot be conducted, the relay K1 still cannot be electrified and attracted, and the short message module A1 cannot be electrified to send a short message to a far-end related person. After a period of time (for example, more than 1 minute), when the capacitor C1 is fully charged, a 12V power supply is subjected to current-limiting and voltage-reducing through the resistors R1 and R2, and then enters the base electrode of the NPN triode Q1 to be higher than 0.7V, the NPN triode Q1 is conducted to conduct the collector electrode to output low level and enter the negative power supply input end of the relay K1, the relay K1 is electrified to attract the control power supply input end and the normally open contact end to be closed, further, the short message module A1 is electrified to send out a short message stored in the inside, after a mobile phone of a far-end related person (for example, an upper-level manager) receives the short message, the user can intuitively know which person is likely to have accidents according to the phone number of the sent short message, and the related person can rescue the wearer as timely as possible, so that unpredictable serious consequences caused by the rescue is reduced. The novel wearer can send a short message after falling to the ground and delaying for 1 minute, so that the problem that under extreme conditions, the wearer can submerge two contacts with mercury in the mercury switch W due to jumping and the like, and then the short message module A1 sends unnecessary short messages; because continuous jump can not cause capacitor C1 to charge in succession, so NPN triode Q1 can not switch on, short message module A1 just can not send the SMS by mistake yet, and the work is more reliable and stable. In fig. 2, relay K1 is a DC12V relay; the voltage display screen V is a small nixie tube display voltmeter (measuring range 12V); the resistance values of the resistors R1, R2 and R3 are 1.16M, 400K and 10K respectively; the capacitor C1 is an electrolytic capacitor of the model 47 mu F/25V; the model Q1 of the NPN triode is 9013; the mercury switch W is a glass shell universal mercury switch; the resistance value of the adjustable resistor RP is 470K (before the production of the embodiment, a technician needs to determine the resistance value of the adjustable resistor RP, specifically, when the distance between the laser ranging module A2 and an object is known, for example, the distance is 80 meters, then the technician adjusts the handle of the adjustable resistor RP left or right to make the resistance value become larger or smaller, when the resistance value of the adjustable resistor RP is adjusted to be larger, the voltage division is larger, and vice versa, the resistance value is adjusted to be in place when the voltage division is just adjusted to be 0.80V as shown by the voltmeter V, and the embodiment is adjusted to be 100K); the laser ranging module A2 is a small-sized laser ranging sensor of the model GJD-01, and is provided with two power input ends and a signal output end, and when the laser ranging sensor works, voltage signals with 0-10V change can be output along with different monitored distances; the short message module A1 and the short message module A3 are short message alarm modules of the model GSM800, the finished product of the short message alarm module is provided with two power input ends 1 and 2 pins, signal input ports 3-8 pins, after each signal input port inputs a low-level signal, the finished product of the short message alarm module can send a short message through a wireless mobile network, the short message alarm module stores the short message with the contents of 'people falling to the ground', and the like, and the short message alarm module can send a short message after the signal input port 3 pin of the short message alarm module is input with the low-level signal.
