Description

Technical Field

[0001] The utility model relates to the technical field of safety devices, in particular to a portable multi-functional outdoor safety device. Background Technique

[0002] When corresponding personnel go to areas with relatively harsh outdoor environments (such as rarely visited mountains, forests, etc., which vary), for outdoor travel or performing work tasks, for safety reasons, they often need to carry some lighting and other auxiliary safety devices with them.

[0003] In the existing technology, the functions of corresponding personal outdoor safety devices are relatively single, generally only having outdoor lighting and active warning functions (such as turning on the power switch when encountering harmful animals, and the alarm sounding to scare and drive away the animals, etc.). In actual situations, various outdoor environments are changeable, and the existing personal outdoor safety devices cannot effectively meet the safety needs, which are specifically reflected as follows. First, it does not have the function of actively prompting remote relevant management personnel when corresponding personnel fall from a height or encounter an emergency. In this way, when various accidents occur to corresponding personnel, due to lack of timely assistance, unpredictable consequences will be caused; Second, it does not have the function of actively detecting and prompting wild animals, etc. When a threatening animal approaches and is not discovered in time, due to the inability to get a warning in advance and relatively little reaction time, there is a probability of being injured by the animal. To sum up, it is very necessary to provide a personal outdoor safety device that is convenient to carry and use and has multiple functions. Summary of the Utility Model

[0004] In order to overcome the drawbacks of the existing personal outdoor safety device due to its structure limitations as described in the background technique, the utility model provides a safety device with a simple and compact structure, convenient to use, based on the existing mature single-chip microcomputer module technology with a Wi-Fi module. In application, under the joint action of relevant mechanisms, it can not only provide lighting function for users, but also can collect the temperature and air pressure data of the corresponding outdoor environment of users in real time, and can also monitor in real time whether there are harmful animals approaching. When a harmful animal approaches, it can actively emit an alarm sound and a stroboscopic light to scare and drive it away, and can actively prompt remote relevant management personnel to arrive at the scene for rescue in time when the user falls from a height or the user encounters an emergency and needs assistance, etc.

The periphery of the middle part of the housing 1 is an open structure. The lighting LED lamp module H and the alarm lamp module H1 are installed in the middle part inside the housing 1 from top to bottom. The millimeter-wave detection module W2 is installed at the upper end inside the housing 1; the two poles of the storage battery G1 and the two ends of the charging socket CZ1 are respectively connected by wires (when the storage battery G1 is out of power, an external power charger plug can be inserted into the charging socket to charge the storage battery G1), and are connected in series through the power switch S1 and the power inputs of the communication and positioning module W1, the millimeter-wave detection module W2, the single-chip microcomputer module W, the barometric pressure and temperature sensor W6 (the detection surface is outside the opening at the corresponding position of the housing, which is conducive to detecting the external barometric pressure and temperature), the electronic compass W7, and the distress switch D1 (connected to the positive pole of the storage battery G1) are connected by wires; the multiple control power output terminals 3 and 4, 5 and 6, 7 and 8 of the single-chip microcomputer module W are respectively connected to the power input terminals of the lighting drive circuit module W4 (a power switch S is connected in series), the power input terminal of the alarm lamp module H1, and the power input terminal of the voltage regulation module W5 by wires. The power output terminal of the lighting drive circuit module W4 is connected to the power input terminal of the lighting LED lamp module H by wires. The power output terminal of the voltage regulation module W5 is connected to the power input terminal of the piezoelectric buzzer B by wires; the signal output terminal 9 port of the single-chip microcomputer module W is connected to the signal input terminal of the communication and positioning module W1 through an SPI data line. The signal output terminals of the millimeter-wave detection module W2, the barometric pressure and temperature sensor W6, and the electronic compass W7 are respectively connected to the signal input ports 10, 11, and 12 of the single-chip microcomputer module W through SPI data lines. The signal output terminal of the distress switch D1 is connected to the trigger signal input terminal 13 port of the single-chip microcomputer module W by wires.

[0017] Figure 1 , 2As shown, around the outer side of the middle part of the housing and surrounding the alarm light module H1 is a transparent protective cover 101 (the outer side of the lighting LED lamp module H does not have a transparent protective cover 101). There are sound transmission holes 102 around the lower end of the housing (to facilitate the transmission of the sound emitted by the piezoelectric buzzer B). The four detection surfaces of the millimeter-wave detection module W2 are located around the upper end inside the housing 1. A condenser hood 103 is installed at the upper end inside the housing. The light-emitting surface of the lighting LED lamp module H is located below the condenser position at the lower end of the condenser hood 103, and a transparent sealed glass 104 is installed at the upper end of the condenser hood. The display interface of the OLED display screen of the single-chip microcomputer module W, multiple operation buttons, the power switches S and S1, and the handle of the distress switch D1 are respectively located outside multiple openings and apertures at the front end of the housing 1. A permanent magnet sheet 2 is adhesively bonded to the lower end of the housing (to facilitate suction on the upper part of the vehicle roof or other objects made of steel materials for use in detecting the approach of animals).

[0018] Figure 1 、 2As shown in the figure, after the power switch S1 is turned on, the communication and positioning module W1, the millimeter-wave detection module W2, the single-chip microcomputer module W, the air pressure and temperature sensor W6, the electronic compass W7, and the distress switch D1 are powered on and work. When the user needs lighting at night, the power switch S is turned on. Then, the signal power output by the single-chip microcomputer module enters the power input terminal of the lighting drive circuit module W4. The user adjusts the dimming button D2 of the single-chip microcomputer module W itself, which can adjust the duty cycle signal voltage entering the lighting drive circuit module W4, and further achieve the purpose of adjusting the power supply voltage of the lighting LED lamp module H. In this way, the lighting LED lamp module H can achieve the purpose of lighting with different brightness levels (the light emitted by the lighting LED lamp module H is collected by the condenser cover and emitted from the front end of the housing). After the air pressure and temperature sensor W6 is powered on and works, it can detect the surrounding air pressure (the pressure is smaller at higher altitudes and vice versa) and temperature signals in real time, and transmit this signal to one of the signal input terminals of the single-chip microcomputer W; after the millimeter-wave detection module W2 (the frequency of the radar wave is 5.8G) is powered on and works, it can detect in real time whether there are harmful animals approaching within a range of 30 meters in the circumferential direction (this functional mode is to reduce the influence of the user himself on the operation of the millimeter-wave detection module W2. Generally, the device is installed about 30 meters away from the user himself, in a position where harmful animals are relatively likely to approach; then, the user uses the existing mature mobile phone APP technology to send a closing control signal through the mobile phone Wi-Fi module. After the Wi-Fi module of the single-chip microcomputer module receives the closing control signal, it controls the millimeter-wave detection module W2 to be powered on and work. When subsequent disarming is required, the user sends an open control signal through the mobile phone Wi-Fi module. After the Wi-Fi module of the single-chip microcomputer module receives the open control signal, it controls the millimeter-wave detection module W2 to lose power and stop working; controlling the output and power-off of devices with Wi-Fi modules through the Wi-Fi module of the mobile phone APP is an existing mature technology, and this application does not claim any protection for this technical solution). After the millimeter-wave detection module W2 detects that an animal (or other person) is approaching, it can output a signal to the second signal input terminal of the single-chip microcomputer W; after the electronic compass W7 is powered on, it will detect the user's azimuth data in real time and output the signal to the third signal input terminal of the single-chip microcomputer W; in actual situations, the user can also press the distress switch D1 (SOS switch) in case of an emergency. Then, the SOS distress signal enters the trigger signal input terminal 13 of the single-chip microcomputer module W.The above-mentioned air pressure, temperature, whether there is an animal approaching, azimuth data, or the SOS distress signal are processed by the single-chip microcomputer module W and then transmitted wirelessly through the communication and positioning module W1. After the relevant management personnel at the remote end receive the corresponding signal through the PC or smartphone application around them, they can timely understand the specific situation and environmental data (including location data) of the user, and notify the relevant nearby personnel or relevant management departments in a timely manner according to specific needs to wait for on-site rescue, etc. (by observing the relevant data, when the air pressure changes sharply from low to high, it means that the user or the device may have accidentally fallen from a height). It should be noted that the communication and positioning module W1 transmits and receives data, and the PC or smartphone displays the relevant data, which are existing mature Internet of Things data transceiver technologies. This application does not claim any protection for the communication and positioning module to transmit and receive data, or the PC or smartphone to display the relevant data. This application only uses the communication and positioning module W1 to receive and the PC or smartphone to display the relevant data of the user on-site.

[0019] Figure 1 、 2 As shown in 2 , in this application, when an animal approaches, after the millimeter-wave detection module W2 outputs a signal, the signal output end of the single-chip microcomputer will output a control power signal to the power input ends of the alarm light module H1 and the voltage adjustment module W5. The alarm light module H1 is powered on and emits a flashing light signal. At the same time, the voltage adjustment module W5 raises the 3.3V voltage signal input by the single-chip microcomputer module to about 12V to drive the piezoelectric buzzer B to emit a loud alarm sound. Under the action of the flashing light signal and the alarm sound, it can effectively warn and drive away the approaching animals, etc., reducing the probability of the user being injured.
