Description

Technical Field

[0001] The present invention relates to the field of construction safety protection, and particularly to a mechanical trigger fall detection engineering operation wearable device, its alarm method, and a fall positioning and search and rescue device. Background Art

[0002] In construction, construction workers need to wear engineering operation wearable devices such as safety helmets with detection, alarm, and positioning functions. In the event of dangerous accidents such as construction safety accidents or accidental accidents, the engineering operation wearable devices give alarms and perform positioning, so that rescue personnel can timely discover the location of the construction workers in the dangerous accident through the positioning and alarm signals and rescue them. In this field, when construction workers fall to the ground in a dangerous accident, usually when triggering the alarm and positioning by a pressure sensor installed on the safety helmet, multiple pressure sensors need to be arranged on the safety helmet from different directions. On the one hand, the cost is high, and on the other hand, there are many wires. When a dangerous accident causes the construction worker to fall to the ground, the pressure sensor is easily damaged or the wires are damaged, resulting in an inability to accurately determine whether the construction worker has fallen to the ground, and thus the pressure sensor as a trigger signal for alarm and positioning is unreliable, and there will be a situation where it does not trigger. In addition, the pressure sensor is affected by the ambient temperature and will show a situation of false triggering, with poor reliability. And using image determination for alarms requires additional labor costs for monitoring, and the camera is not installed on the safety helmet, and there are also problems with unreliable camera judgments. Summary of the Invention

[0003] The object of the present invention is to provide a mechanical trigger fall detection engineering operation wearable device, its alarm method, and a fall positioning and search and rescue device to solve the problem of unreliable judgment of whether to trigger the positioning alarm signal through a pressure sensor when a construction worker falls to the ground in a dangerous accident.

[0004] To solve the above technical problems, the present invention provides a mechanical trigger fall detection engineering operation wearable device, including an engineering operation wearable device and a mechanical trigger fall detection device detachably arranged vertically thereon.

[0005] Further, in the mechanical trigger fall detection engineering operation wearable device provided by the present invention, the engineering operation wearable device is a safety helmet, and the mechanical trigger fall detection device is detachably installed on the brim of the safety helmet through a detection box.

[0006] Further, in the mechanical trigger fall detection engineering operation wearable device provided by the present invention, the mechanical trigger fall detection device includes:

[0007] A housing having two chambers;

[0008] An alarm module is installed in one of the chambers. The alarm module includes a rechargeable battery, a controller, and a locator connected thereto;

[0009] A trigger module is installed in another chamber. This chamber is divided into an upper bin and a lower bin by an insulating board. The trigger module includes a mechanical upper trigger module located in the upper bin and a mechanical lower trigger module located in the lower bin;

[0010] The mechanical upper trigger module includes a negative conductive ring plate, a positive electrode elastic sheet, and a swinging ball. The negative conductive ring plate is arranged around the inner wall of the upper part of the upper bin. The negative conductive ring plate is connected to the ground wire of the controller of the alarm module. There are multiple positive electrode elastic sheets, which are vertically distributed around the upper bin. The lower end of each positive electrode elastic sheet is fixed on the insulating board, and the upper end does not touch the top of the upper bin and is located within the area of the negative conductive ring plate to form a free end. Each positive electrode elastic sheet is connected to a control port of the controller of the alarm module. The swinging ball is located at the center of the positively elastic sheets distributed around. The swinging ball includes a spring and a metal ball connected to one end thereof. The other end of the spring is vertically connected to the insulating board. The metal ball does not touch the top of the upper bin and is located within the area of the negative conductive ring plate to form a free ball;

[0011] The mechanical lower trigger module includes a positive electrode metal ring, a suspended metal rod, and a negative electrode metal ring. The positive electrode metal ring is arranged at the center of the lower surface of the insulating board and is connected to another control port of the controller of the alarm module. The suspended metal rod is hinged on the positive electrode metal ring. The lower end of the suspended metal rod does not touch the bottom of the lower bin. The negative electrode metal ring is suspended on the insulating board and is connected to the ground wire of the controller of the alarm module;

[0012] When a construction worker wearing a mechanical trigger fall detection engineering operation wearable device falls, the swinging ball of the mechanical upper trigger module of the trigger module of the mechanical trigger fall detection device swings under the constraint of the lower end of the spring and impacts the positive electrode elastic sheet on the side where the falling direction is located, making it fit and contact the negative conductive ring plate on the corresponding side, so that the positive electrode elastic sheet and the negative conductive ring plate are in an on state. The controller determines that the mechanical upper trigger module is in an on state; at the same time, the suspended metal rod of the mechanical lower trigger module of the trigger module impacts the negative electrode metal ring on the side where the falling direction is located under the constraint generated at the upper end of the positive electrode metal ring to which it is hinged, making the suspended metal rod, the positive electrode metal ring, and the negative electrode metal ring in contact and in an on state. The controller determines that the mechanical lower trigger module is in an on state; when both the mechanical upper trigger module and the mechanical lower trigger module are in an on state, the controller generates a trigger signal to control the locator to send out a positioning alarm signal.

[0013] Furthermore, for the mechanical trigger fall detection engineering operation wearable device provided by the present invention, the trigger module further includes:

[0014] The manual trigger switch is set on the engineering operation wearable device and is connected to the controller of the mechanical trigger fall detection device.

[0015] Furthermore, for the mechanical trigger fall detection engineering operation wearable device provided by the present invention, the alarm module further includes:

[0016] A buzzer, connected to the controller;

[0017] An alarm lamp, connected to the controller.

[0018] Furthermore, for the engineering operation wearable device provided by the present invention, the alarm module of the mechanical trigger fall detection device further includes:

[0019] A dial switch is set on the engineering operation wearable device and is connected to the control loop of the alarm lamp between the controller of the mechanical trigger fall detection device.

[0020] Furthermore, for the mechanical trigger fall detection engineering operation wearable device provided by the present invention, the upper part of the positive electrode elastic sheet is a concave circular arc.

[0021] Furthermore, the mechanical trigger fall detection engineering operation wearable device provided by the present invention further includes:

[0022] A spare battery box is set on the engineering operation wearable device, and a spare battery is detachably installed therein. The spare battery is connected to the rechargeable battery of the alarm module of the mechanical trigger fall detection device in the detection box through an electric wire.

[0023] In order to solve the above technical problems, the present invention provides an alarm method for the above-mentioned mechanical trigger fall detection engineering operation wearable device.

[0024] Wear the mechanical trigger fall detection engineering operation wearable device on the head of the construction worker.

[0025] When the construction worker is performing normal construction operations, the mechanical trigger fall detection engineering operation wearable device and the mechanical trigger fall detection device therein are in a vertical state. The mechanical upper trigger module and the mechanical lower trigger module of the trigger module are in a disconnected state, and the controller does not generate a trigger signal. It is judged that the construction worker has not had a fall hazard accident, and the locator does not emit a positioning alarm signal.

[0026] When the construction worker is tilted but not fallen, the mechanical trigger fall detection engineering operation wearable device and the mechanical trigger fall detection device therein are in an inclined state towards one direction. Only one of the mechanical upper trigger module and the mechanical lower trigger module of the trigger module is in an on state, and the controller does not generate a trigger signal. It is judged that the construction worker has not had a fall hazard accident, and the locator does not emit a positioning alarm signal.

[0027] When the construction worker falls to the ground, when the mechanical trigger fall detection engineering operation wearable device and the mechanical trigger fall detection device therein change from the vertical state to the horizontal state, at least once the mechanical upper trigger module of the trigger module is in the on state, and the mechanical lower trigger module is in the on state. The controller generates a trigger signal, the controller determines that a dangerous accident has occurred to the construction worker falling to the ground, and the controller controls the locator to send a positioning alarm signal.

[0028] Compared with the prior art, the beneficial effects of the mechanical trigger fall detection engineering operation wearable device and its alarm method provided by the present invention are as follows:

[0029] When a dangerous accident occurs to a construction worker and the worker falls to the ground, when the mechanical trigger fall detection device of the mechanical trigger fall detection engineering operation wearable device is in the on state, it is used as a trigger signal for positioning and alarming. When the mechanical trigger fall detection device of the mechanical trigger fall detection engineering operation wearable device is in the off state, it is used as a non-trigger signal and no positioning and alarming is performed. Thus, when a dangerous accident occurs to a construction worker and the worker falls to the ground, the positioning alarm signal of the mechanical trigger fall detection engineering operation wearable device can be reliably triggered, avoiding the problem that when electronic components such as pressure sensors fall to the ground along with the construction worker, the circuit is damaged and no trigger signal is generated, or the electronic components are affected by temperature and generate a false trigger signal to send a positioning alarm signal during the normal work of the construction worker.

[0030] To solve the above technical problems, the present invention also provides a fall positioning and search and rescue device, which adopts the above-mentioned mechanical trigger fall detection engineering operation wearable device, including:

[0031] A mobile communication module, connected to the controller, is arranged in the mechanical trigger fall detection device, and is used for sending out the positioning alarm signal of the locator;

[0032] A remote alarm module, which is used for remotely receiving the positioning alarm signal of the engineering operation wearable device.

[0033] Compared with the prior art, the beneficial effects of the fall positioning and search and rescue device provided by the present invention are as follows:

[0034] The search and rescue personnel search for the construction worker who has fallen to the ground after a dangerous accident according to the positioning alarm signal sent by the mobile communication module of the mechanical trigger fall detection engineering operation wearable device received by the remote alarm module, so as to strive for rescue time when rescuing the construction worker who has fallen to the ground after a dangerous accident.

[0052] The present invention will be described in detail below with reference to the accompanying drawings: According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the accompanying drawings are all in a very simplified form and use non-precise scales, only for the purpose of conveniently and clearly assisting in explaining the embodiments of the present invention.

[0053] Please refer to Figures 1 to 9 , The embodiment of the present invention provides a mechanical trigger fall detection engineering operation wearable device, including an engineering operation wearable device 200 and a mechanical trigger fall detection device 100 detachably arranged vertically thereon. Among them, the engineering operation wearable device 200 is limited to safety helmets, clothes, trousers, belts, shoes, safety vests, etc., and cannot be a smart bracelet. The mechanical trigger fall detection device 100 is limited to being installed on the trunk part of the engineering operation wearable device 200 of construction workers and cannot be an arm. Figure 6 In the example, the engineering operation wearable device 200 is a safety helmet. At this time, the mechanical trigger fall detection device 100 is detachably installed on the brim of the safety helmet through the detection box 210. Among them, the mechanical trigger fall detection device 100 is installed on the detection box 210 in a modular design, which has the advantages of being disassembled and replaced and being convenient for maintenance.

[0054] For the mechanical trigger fall detection engineering operation wearable device 200 provided by the embodiment of the present invention, when a construction worker has a dangerous accident and falls to the ground, when the mechanical trigger fall detection device 100 of the mechanical trigger fall detection engineering operation wearable device 200 is in the on state, it is used as a trigger signal for positioning and alarming. When the mechanical trigger fall detection device 100 of the mechanical trigger fall detection engineering operation wearable device 200 is in the off state, it is used as a non-trigger signal and no positioning and alarming is performed. Thus, when a construction worker has a dangerous accident and falls to the ground, the positioning alarm signal of the mechanical trigger fall detection engineering operation wearable device 200 can be reliably triggered, avoiding the problem that when electronic components such as pressure sensors fall to the ground with construction workers, the circuit is damaged and no trigger signal is generated, or the electronic components are affected by temperature and generate false trigger signals during the normal work of construction workers to send out positioning alarm signals.

[0055] Please refer to Figures 1 to 4 , Figure 8, the mechanical trigger fall detection engineering operation wearable device 200 provided by the embodiment of the present invention, the mechanical trigger fall detection device 100 may include:

[0056] A housing 110 having two chambers 111. The two chambers 111 can be distributed left and right, or up and down. Under the condition of sufficient installation space, the two chambers 111 can be combined into one.

[0057] An alarm module 120 is installed in one of the chambers 111. The alarm module 120 includes a rechargeable battery 128, a controller 121 and a connected locator 122. The controller 121 controls the locator 122 to generate a positioning alarm signal according to the trigger signal. The rechargeable battery 128 supplies power to the controller 121. The controller 121 may also be connected to a buzzer 123 and an alarm light 124 and their combination. At this time, the controller 121 can control the buzzer 123 to emit a sound alarm signal and the alarm light 124 to emit a light alarm signal according to the trigger signal. The controller 121, the locator 122, the buzzer 123 and the alarm light 124 are usually carried by a printed circuit board to reduce the connecting wires. When the installation space is sufficient, the controller 121, the locator 122 and the buzzer 123 can also be arranged on different layers of the chamber 111 where they are located by wire layering and partitioning. In addition, the alarm light 124 can also be used for lighting. The controller 121 includes, but is not limited to, a single-chip microcomputer. The buzzer 123 and the alarm light 124 are both optional components to provide position guidance for on-site rescue. The locator 122 is a GPS positioning chip.

[0058] A trigger module 130 is installed in the other chamber 111. The chamber 111 is divided into an upper chamber and a lower chamber by an insulating plate 111. The trigger module 130 includes a mechanical upper trigger module 131 located in the upper chamber and a mechanical lower trigger module 132 located in the lower chamber.

[0059] Among them, the mechanical upper trigger module 131 includes a negative conductive ring piece 1311, a positive elastic piece 1312 with a certain elastic coefficient, and a swinging ball. The negative conductive ring piece 1311 is arranged around the inner wall of the upper part of the upper bin. The negative conductive ring piece 1311 is connected to the ground wire of the controller 121 of the alarm module 120. There are multiple positive elastic pieces 1312, which are vertically distributed around in the upper bin. The lower end of each positive elastic piece 1312 is fixed on the insulating board 111, and the upper end does not contact the top of the upper bin and is located within the area of the negative conductive ring piece 1311 to form a free end. Each positive elastic piece 1312 is connected to a control port of the controller 121 of the alarm module 120. The swinging ball is located at the center of the positively elastic pieces 1312 distributed around. The swinging ball includes a spring 1313 with a certain stiffness coefficient and a metal ball 1314 connected to one end thereof. The other end of the spring 1313 is vertically connected to the insulating board 111. The metal ball 1314 does not contact the top of the upper bin and is located within the area of the negative conductive ring piece 1311 to form a free ball.

[0060] Among them, the mechanical lower trigger module 132 includes a positive metal ring 1321, a suspended metal rod 122, and a negative metal ring 1323. The positive metal ring 1321 is arranged at the center of the lower surface of the insulating board 111 and is connected to another control port of the controller 121 of the alarm module 120. The suspended metal rod 122 is hinged on the positive metal ring 1321. The lower end of the suspended metal rod 122 does not contact the bottom of the lower bin. The negative metal ring 1323 is suspended on the insulating board 111 and is connected to the ground wire of the controller 121 of the alarm module 120.

[0061] Please refer to Figures 1 to 2 , when the construction worker wearing the mechanical trigger fall detection engineering operation wearable device 200 does not fall, the swinging ball of the mechanical upper trigger module 131 of the trigger module 130 is in a vertical state, and the metal ball 1314 of the swinging ball does not occur with each positive elastic piece 1312. The positive elastic piece 1312 and the negative conductive ring piece 1311 are in a disconnected state, and the controller determines that the mechanical upper trigger module 131 is in a disconnected state; the suspended metal rod 1322 of the mechanical lower trigger module 132 of the trigger module is in a suspended state and does not contact the negative metal ring 1323, so that the suspended metal rod 1322, the positive metal ring 1321, and the negative metal ring 1323 are in a disconnected state, and the controller 121 determines that the mechanical lower trigger module 132 is in a disconnected state.

[0062] Please refer to with emphasis Figure 5 and Figure 8, when a construction worker wearing the mechanical trigger fall detection engineering operation wearable device 200 topples over, the metal ball 1314 of the swinging ball of the mechanical upper trigger module 131 of the mechanical trigger fall detection device 100 inside it swings under the constraint of the lower end of the spring 1313 and impacts the positive elastic sheet 1312 on the side where the toppling direction is located, causing it to fit and contact the negative conductive ring sheet 1311 on the corresponding side, so that the positive elastic sheet 1312 and the negative conductive ring sheet 1311 are in a conducting state, and the controller 121 determines that the mechanical upper trigger module 131 is in a conducting state; at the same time, the suspended metal rod 122 of the mechanical lower trigger module 132 of the trigger module 130 impacts the negative metal ring 1323 on the side where the toppling direction is located under the constraint of the upper end of the positive metal ring 1321 to which it is hinged, so that the suspended metal rod 1322, the positive metal ring 1321 and the negative metal ring 1323 are in contact and in a conducting state, and the controller 121 determines that the mechanical lower trigger module 132 is in a conducting state. When both the mechanical upper trigger module 131 and the mechanical lower trigger module 132 are in a conducting state, the controller 121 generates a trigger signal to control the locator 122 to send out a positioning alarm signal. Among them, when the construction worker wearing the mechanical trigger fall detection engineering operation wearable device 200 is in a stable state after toppling over, the metal ball 1314 of the swinging ball returns to its original state under the elastic force of the spring 1313. At this time, the positive elastic sheet 1312 in contact with the negative conductive ring sheet 1311 returns to its original state, that is, neither the swinging ball nor the positive elastic sheet 1312 is in contact with the negative conductive ring sheet 1311. So as to perform secondary detection when the construction worker wearing the mechanical trigger fall detection engineering operation wearable device 200 topples over again or changes position when the dangerous accident has not stopped, and the controller 121 triggers the control locator 122 to send out a positioning alarm signal for the second time, so as to judge the toppling position of the construction worker according to the positioning alarm signal triggered last time, improving the accuracy and real-time performance of the positioning judgment of the construction worker in case of dangerous accidents.

[0063] The embodiment of the present invention also provides an alarm method according to the above-mentioned mechanical trigger fall detection engineering operation wearable device 200, including:

[0064] Step 401, wear the mechanical trigger fall detection engineering operation wearable device 200 on the body of a construction worker.

[0065] Step 402: When construction workers are performing normal construction operations, the mechanical trigger fall detection engineering operation wearable device 200 and the mechanical trigger fall detection device 100 therein are in a vertical state. The mechanical upper trigger module 131 and the mechanical lower trigger module 132 of the trigger module 130 are in a disconnected state, and the controller 121 does not generate a trigger signal. It is determined that the construction workers have not encountered a fall hazard accident, and the locator 122 does not emit a positioning alarm signal, as Figure 2 shown.

[0066] Step 403: When the construction workers are tilted but not fallen, the mechanical trigger fall detection engineering operation wearable device 200 and the mechanical trigger fall detection device 100 therein are in an inclined state towards one direction. Only one of the mechanical upper trigger module 131 and the mechanical lower trigger module 132 of the trigger module 130 is in an on state, and the controller 121 does not generate a trigger signal. It is determined that the construction workers have not encountered a fall hazard accident, and the locator 122 does not emit a positioning alarm signal.

[0067] Step 404: When the construction workers fall, when the mechanical trigger fall detection engineering operation wearable device 200 and the mechanical trigger fall detection device 100 therein change from a vertical state to a horizontal state, the mechanical upper trigger module 131 of the trigger module 130 is in an on state at least once, and the mechanical lower trigger module 132 is in an on state. The controller 121 generates a trigger signal. The controller 121 determines that the construction workers have encountered a fall hazard accident. The controller 121 controls the locator 122 to emit a positioning alarm signal, as Figure 5 shown.

[0068] For the mechanical trigger fall detection engineering operation wearable device 200 and its alarm method provided in the embodiment of the present invention, when the construction workers wearing the mechanical trigger fall detection engineering operation wearable device 200 are tilted but not fallen, one of the mechanical upper trigger module 131 and the mechanical lower trigger module 132 of the trigger module 130 is in an on state and the other is in an off state. At this time, the controller 121 does not generate a trigger signal to prevent the controller 121 from misjudging when the construction workers wearing the mechanical trigger fall detection engineering operation wearable device 200 are performing inclined operations and wrongly determining that the construction workers wearing the mechanical trigger fall detection engineering operation wearable device 200 have fallen. That is, for the mechanical trigger fall detection engineering operation wearable device 200 provided in the embodiment of the present invention, through the dual-channel judgment of the mechanical upper trigger module 131 and the mechanical lower trigger module 132, when both the mechanical upper and lower trigger modules are in an on state, it is determined that the construction workers wearing the mechanical trigger fall detection engineering operation wearable device 200 have fallen, generating a trigger signal, so that the controller 121 controls the locator 122 to emit a positioning alarm signal. It is not easy to misjudge and will not generate false trigger signals.

[0069] Please refer to Figure 6 and Figures 8 to 9 For the mechanical trigger fall detection engineering operation wearable device 200 and its alarm method provided by the embodiments of the present invention, the trigger module 130 may further include:

[0070] A manual trigger switch 133 is provided on the engineering operation wearable device 200 and is connected to the controller 121 of the mechanical trigger fall detection device 100. In the alarm method at this time, when the manual trigger switch 133 is closed, the controller 121 generates a trigger signal to control the locator 122 to send out a positioning alarm signal. The manual trigger switch 133 can actively trigger the positioning alarm through the manual trigger switch 133 when the mechanical trigger module fails to trigger the positioning alarm during the fall or collapse of construction workers in major safety accidents or accidents, and the construction workers are conscious and their arms can move. When the engineering operation wearable device 200 is a safety helmet, the manual trigger switch 133 is provided on one side of the left and right sides of the safety helmet. Pressing the manual trigger switch 133 again can cancel the active trigger alarm.

[0071] Please refer to Figure 7 and Figure 8 For the mechanical trigger fall detection engineering operation wearable device 200 and its alarm method provided by the embodiments of the present invention, the alarm module 120 of the mechanical trigger fall detection device 100 may further include:

[0072] A dial switch 127 is provided on the engineering operation wearable device 200 and is connected to the control loop of the controller 121 of the mechanical trigger fall detection device 100 and the alarm lamp 124. In the alarm method, the brightness of the alarm lamp 124 can be adjusted through the dial switch 127 at this time, so as to use the alarm lamp 124 as a lighting lamp to provide lighting for the fallen construction workers in the environment where they are located, and avoid secondary dangers in a dark environment.

[0073] Please refer to Figure 2 In order to improve the reliable contact between the positive electrode elastic piece 1312 and the metal ball 1314 of the swing ball, for the mechanical trigger fall detection engineering operation wearable device 200 provided by the embodiments of the present invention, the upper part of the positive electrode elastic piece 1312 is a concave circular arc. When the swing ball swings, the metal ball 1314 thereon can be limited within the concave circular arc of the positive electrode elastic piece 1312 and drive the positive electrode elastic piece 1312 to contact the negative conductive ring piece 1311. In order to improve the reliable connection of multiple positive electrode elastic pieces 1312, the positive electrode elastic piece 1312 is arranged on the insulating board 111 through an annular bottom plate (not shown). The annular bottom plate can ensure the integrity, installation convenience, and installation height consistency of each positive electrode elastic piece 1312.
