Description

Technical Field

[0001] The invention relates to the technical field of vibration alarms, and in particular to a vibration alarm device based on a MEMS sensor. Background Art

[0002] MEMS sensors can sense external vibration signals and convert them into electrical signals. These sensors usually contain tiny movable structures. When subjected to vibration, their electrical properties such as capacitance, resistance or inductance will change. The electrical signal output by the sensor is relatively weak and may contain noise. It needs to be amplified, filtered and shaped by the signal processing circuit to extract useful vibration feature information. The alarm output module sends an alarm signal to the remote monitoring equipment through the communication module to attract the attention of relevant personnel. In short, the vibration alarm device based on MEMS sensors realizes timely and accurate alarm function by accurately sensing vibration, effectively processing signals and accurately judging thresholds, and is often used for anti-theft.

The vibration is sensed by the vibration sensor, and an electrical signal is generated after the vibration is sensed. The analysis circuit receives the signal for analysis and processing, determines the amplitude of the vibration according to the preset logic, and controls the alarm to sound an alarm when the vibration amplitude is greater than the preset value, so as to realize a sensitive vibration alarm.

When someone approaches, it will transmit an abnormal signal to the controller. At this time, the vibration alarm will vibrate and there is a risk of theft, thereby sounding an alarm. The principle of the pyroelectric sensor's sensitivity to changes in human body temperature is that the human body is a good infrared radiation source, whose body temperature is usually constant and will continuously radiate infrared rays in a specific wavelength range.

The outer surfaces of the multiple receiving tubes 205 are fixedly connected to the observation tubes 206, and the inner walls of the multiple observation tubes 206 are fixedly installed with a primary magnifying glass 208. A plurality of observation holes 310 are provided on the outer surface of one side of the protective cover 301 near the slide groove 309, and the inner walls of the multiple observation holes 310 are fixedly installed with a secondary magnifying glass 207, and one end of each observation tube 206 is fixedly connected to one end of each observation hole 310.

[0036] In this embodiment, when in use, the main body component 1 and the cover body component 3 are installed together to form a complete vibration alarm device. The installation position of the lubricating component 2 corresponds to the position of the main spring 108. After the vibration alarm device has been used for a long time, the main spring 108 inside it will be fatigued and worn. Before the fixing box 201 is installed on the protective cover 301, the lubricating oil bursting bead 210 wrapped with lubricating oil is placed between the inner walls of each receiving tube 205. When placed, it is tightly plugged, and there is friction between the outer leather of the bursting bead and the inner wall of the receiving tube 205. Therefore, the lubricating oil bursting bead 210 itself will not fall off. A layer of color-changing test paper 209 is set on the outside of the lubricating oil bursting bead 210. The color-changing test paper 209 is close to the receiving tube 205. The pipe 205 is placed, and the maintenance time is set during use. When the maintenance time is reached, the push block 216 is pressed and pushed forward. When pushing, it should be along the inner wall of the movable groove 215, and the pushing speed should be slow, and the distance pushed at one time should be short. This is because the length of each adjustment rod 212 is different, and the shortest length is set to the first adjustment rod 212. In the initial state, the distance between each rear adjustment rod 212 and the adjacent movable block 211 is increased. Then, by pushing the push block 216, the slider 217 can be driven to slide inside the movable groove 215 and the slide groove 309, and at the same time, the fixing ring 218 and the connecting rod 220 can be driven to move. When moving, the first adjustment rod 212 is installed The scraper 214 installed will pass through the top of the lubricating oil bursting bead 210, scratch the lubricating oil bursting bead 210, and make the internal lubricating oil leak out. The leaked lubricating oil will flow into the delivery pipe 204 from the corresponding position of the receiving pipe 205, and reach the connecting pipe 202 after passing through the delivery pipe 204, and finally drip from each leakage nozzle 203 onto the main spring 108 and its metal mounting plate, thereby achieving lubrication maintenance of the main spring 108 and its metal mounting plate, avoiding the situation in the prior art that the main spring 108 is fatigued and worn after long-term use and affecting the use, and there is no need to disassemble the entire vibration alarm device for maintenance, thereby improving convenience. Among them, the size of the receiving pipe 205 and the lubricating oil bursting bead 210 can be selected to have a larger capacity In addition, the lubricating oil flowing out will soak the color-changing test paper 209. The color-changing test paper 209 chooses to use the moisture detection test paper in oil, which will change color after being soaked by the lubricating oil. At this time, since the observation tube 206 is connected to the receiving tube 205, the color of the color-changing test paper 209 will be magnified by the primary magnifying glass 208 when it changes, and the secondary magnifying glass 207 will magnify the content displayed by the primary magnifying glass 208 again, so that the user can very intuitively observe whether the lubricating oil has been used. When it is necessary to scratch the lubricating oil bursting beads 210 at different positions, it is only necessary to push the push block 216. Whether the lubricating oil bursting beads 210 are successfully scratched each time only needs to be observed through the secondary magnifying glass 207 on the observation hole 310.The multiple lubricating oil bursting beads 210 are provided here to facilitate indirect lubrication maintenance in multiple time periods, so that a large amount of lubricating oil will not enter the interior of the vibration alarm and cause damage to the electronic component board 107.

Since strong winds and human shaking will cause the vibration alarm to vibrate, thereby sounding an alarm, the vibration alarm is mostly used for anti-theft. The vibration caused by strong winds does not belong to theft, which will cause the vibration alarm to misjudge. Therefore, a pyroelectric sensor 106 and a controller 109 are set on the mounting plate 105, and the two are electrically connected, and the controller 109 is electrically connected to the controller 109. 09 is also electrically connected to the electronic components on the electronic component board 107.

When someone approaches, the abnormal signal is transmitted to the controller 109. At this time, the vibration alarm vibrates and there is a risk of theft, thereby sounding an alarm. The principle that the pyroelectric sensor 106 is sensitive to changes in human body temperature is that the human body is a good infrared radiation source, whose body temperature is usually constant and will continuously radiate infrared rays in a specific wavelength range. The pyroelectric material in the pyroelectric sensor 106 has a unique spontaneous polarization characteristic. When it receives infrared rays radiated by the human body, the material temperature will change.

Most of the heat generated inside the vibration alarm will be absorbed by the heat conduction plate 311, and then dissipated through the heat dissipation port 305. At the same time, the fixed mesh plate 307 also has a heat dissipation effect. A waterproof and breathable membrane 304 of matching size is laid on the fixed mesh plate 307, and then the closed mesh plate 303 is clamped on the outside of the card frame 306, so that the waterproof and breathable membrane 304 is tightened. The waterproof and breathable membrane 304 has a unique microporous structure, which can effectively prevent the entry of liquid water while allowing gas molecules to pass through, including air molecules required for sound propagation. It can achieve the waterproof function while basically not affecting the outward propagation of sound. When it needs to be removed, the closed mesh plate 303 is taken out with the help of the groove 308.

[0043] The method of use and working principle of the device: When in use, the main body component 1 and the cover body component 3 are installed together to form a complete vibration alarm device. The installation position of the lubricating component 2 corresponds to the position of the main spring 108. After the vibration alarm device has been used for a long time, the main spring 108 inside it will be fatigued and worn. Before installing the fixing box 201 on the protective cover 301, the lubricating oil bursting bead 210 wrapped with lubricating oil is placed between the inner walls of each receiving tube 205. When placed, it is tightly plugged, and there is friction between the outer leather of the bursting bead and the inner wall of the receiving tube 205, so the lubricating oil bursting bead 210 itself will not fall off. A layer of color-changing test paper 209 is set on the outside of the lubricating oil bursting bead 210. The color-changing test paper 209 is It is placed close to the receiving tube 205, and the maintenance time is set during use. When the maintenance time is reached, the push block 216 is pressed to push the push block 216 forward. When pushing, it should be along the inner wall of the movable groove 215, and the pushing speed should be slow, and the distance pushed at one time should be short. This is because the length of each adjustment rod 212 is different, and the shortest length is set to the first adjustment rod 212. In the initial state, the distance between each rear adjustment rod 212 and the adjacent movable block 211 is increased. Then, by pushing the push block 216, the slider 217 can be driven to slide inside the movable groove 215 and the slide groove 309, and at the same time, the fixing ring 218 and the connecting rod 220 can be driven to move. When moving, the first adjustment rod 212 The installed scraper 214 will pass through the top of the lubricating oil bursting bead 210, scratch the lubricating oil bursting bead 210, and make the internal lubricating oil leak out. The leaked lubricating oil will flow into the delivery pipe 204 from the corresponding receiving pipe 205, and reach the connecting pipe 202 after passing through the delivery pipe 204, and finally drip from each leakage nozzle 203 onto the main spring 108 and its metal mounting plate. Among them, the size of the receiving pipe 205 and the lubricating oil bursting bead 210 can be selected with a larger capacity. In addition, the lubricating oil that flows out will soak the color-changing test paper 209. The color-changing test paper 209 chooses to use the oil moisture detection test paper, which will change color after being soaked by the lubricating oil. At this time, since the observation tube 206 is connected to the receiving pipe 205, the color-changing test paper 209 When the color of changes, it will be magnified by the primary magnifying glass 208, and the secondary magnifying glass 207 will magnify the content displayed by the primary magnifying glass 208 again, so that the user can very intuitively observe whether the lubricating oil has been used. When it is necessary to scratch the lubricating oil bursting beads 210 at different positions, it is only necessary to push the push block 216. Whether the lubricating oil bursting beads 210 are successfully scratched each time can be observed through the secondary magnifying glass 207 on the observation hole 310. The multiple lubricating oil bursting beads 210 are arranged here to facilitate indirect lubrication maintenance in multiple time periods, and will not cause a large amount of lubricating oil to enter the interior of the vibration alarm to damage the electronic component board 107.

Strong wind and human shaking will cause the vibration alarm to vibrate, thereby sounding an alarm. The vibration alarm is mostly used for anti-theft. The vibration caused by strong wind does not belong to theft, which will cause the vibration alarm to misjudge. Therefore, a pyroelectric sensor 106 and a controller 109 are arranged on the mounting plate 105, and the two are electrically connected, and the controller 109 is also electrically connected to the electronic components on the electronic component board 107. The pyroelectric sensor 106 is sensitive to changes in human body temperature and can be used to detect the approach of a person. When someone approaches, the abnormal signal is transmitted to the controller 109. At this time, the vibration alarm vibrates and there is a risk of being stolen, thereby sounding an alarm. Among them, the principle that the pyroelectric sensor 106 is sensitive to changes in human body temperature is: the human body is a good The infrared radiation source of the human body usually has a constant body temperature and will continuously radiate infrared rays of a specific wavelength range. The pyroelectric material in the pyroelectric sensor 106 has a unique spontaneous polarization characteristic. When it receives infrared rays radiated by the human body, the material temperature will change. When in use, by matching the protective cover 301 with the fixed shell 101, and making each threaded hole 102 and the mounting hole 302 correspond, and then using the fastening screw 5 to pass through the mounting hole 302 and screw it into the threaded hole 102, the installation between the protective cover 301 and the fixed shell 101 is completed. Most of the heat generated inside the vibration alarm will be absorbed by the heat conducting plate 311, and then dissipated through the heat dissipation port 305. At the same time, the fixed mesh plate 307 also has a heat dissipation effect. A waterproof and breathable membrane 304 of matching size is laid on the fixed mesh plate 307, and then the closed mesh plate 303 is clamped on the outside of the card frame 306, so that the waterproof and breathable membrane 304 is tightened. When it needs to be removed, the closed mesh plate 303 is taken out with the help of the pull groove 308. ,
