Description

Technical Field

[0001] This invention relates to the field of child safety monitoring devices, specifically to a child monitoring watch with a water immersion alarm function and its usage method. Background Technology

[0002] Child monitoring watches typically integrate functions such as positioning, communication, and alarms. They can obtain the child's current location through the positioning module and send alerts to the monitoring device when the child leaves a preset area or when an abnormal situation occurs. Existing child monitoring watches already have a certain monitoring function in scenarios such as children going out, going to school, and playing. However, they still have insufficient specificity in scenarios near bodies of water such as rivers, lakes, reservoirs, ponds, and the sea. Existing devices mostly focus on location viewing or ordinary electronic fence alerts, and usually cannot combine water location information to determine whether a child is approaching the water, nor can they provide effective water risk warnings before a child falls into the water. At the same time, some devices have the water fall detection function enabled for a long time, which can easily cause false triggers when washing hands, getting wet in the rain, playing in water, or splashing water briefly. When the detection function is turned off, it may not be able to respond in time to the actual risk of falling into the water.

[0003] Furthermore, existing child monitoring watches typically rely on sound alerts, vibration alerts, or sending location information to the monitoring device to trigger alarms after a child falls into water. While these methods provide some degree of remote notification, in real-world rescue scenarios, factors such as water currents, struggling, obstructions, and insufficient light can make it difficult for on-site personnel to quickly pinpoint the child's location in the water. Simply relying on electronic positioning or sound alarms is insufficient to meet the needs of rapid on-site search. Therefore, there is an urgent need for a child monitoring watch that can selectively activate water identification based on the distance between the child and the water, issue warnings when the child is near the water, trigger an alarm after water identification, and simultaneously assist in visual positioning at the scene.

[0012] Preferably, the water-fall recognition module is used to determine the dye discharge status based on the watch's motion data, and the dye discharge status includes a stopped discharge status, an intermittent discharge status, or a continuous discharge status.

[0013] Preferably, the alarm module is used to output a second alarm signal after receiving the identification signal, and the communication module is used to send a second alarm message to the monitoring terminal, the second alarm message including the watch location information.

[0014] In a second aspect of the present invention, a method for using a child monitoring watch with water-fall detection function is provided, comprising the following steps: S1, obtain the watch's location information through the positioning module; S2, the processing module receives the watch's location information and calculates the distance between the watch body and the water area based on the watch's location information and the water area location information in the database; when the distance is less than a preset threshold, the processing module activates the water fall detection module and generates a first warning signal; S3, the alarm module outputs a first prompt based on the first warning signal, or the communication module sends the first warning alarm information to the monitoring terminal; S4, the communication module receives the control command sent by the monitoring terminal, the processing module controls the first prompt to stop or maintain according to the control command, and continues to determine whether to activate the water fall detection module according to the watch location information and the water area location information; S5, the water-drop detection module identifies whether the watch body is in water when it is activated, and generates a detection signal when it identifies that the watch body is in water; S6, the alarm module receives the identification signal and outputs a second alarm signal, and the communication module sends a second alarm message to the monitoring terminal, the second alarm message including the watch location information; S7, the water-dropping recognition module acquires the watch's motion data and controls the discharge of dye based on the watch's motion data to form a visual positioning mark when the watch body is in water.

[0015] One or more technical solutions provided in this application have at least the following technical effects or advantages: This invention provides a child monitoring watch with a water ingress alarm function and its usage method. The watch's location information is obtained through a positioning module, and the processing module calculates the distance between the watch and the water location information using water location information in a database. When the distance is less than a preset threshold, the water ingress detection module is activated, ensuring that the module only enters detection mode when the child approaches the water and stops detection when the child moves away from the water, thereby reducing the probability of invalid detection and false alarms in non-water scenarios. Simultaneously, the processing module generates a first warning signal when the child approaches the water, the alarm module outputs a first alert, and the communication module sends the first warning alarm information to the monitoring device, enabling both the child and the guardian to be aware of the water risk before the child falls into the water. It can also receive control commands sent by the monitoring terminal, enabling the processing module to control the first warning to stop or maintain. After the first warning stops, it continues to determine whether to activate the water fall detection module based on the watch's location information and the water area location information, to prevent the water fall detection function from failing after the warning is lifted. After the water fall detection module detects that the watch is in the water, the alarm module outputs a second alarm signal, and the communication module sends the second alarm information, including the watch's location information, to the monitoring terminal. Furthermore, the water fall detection module can control the discharge of dye based on the watch's movement data to form a visual positioning mark in the water, thereby realizing hierarchical linkage of proximity warning, water fall detection alarm, and on-site auxiliary positioning, improving the reliability of monitoring and rescue efficiency for children in water-risk scenarios.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0021] like Figures 1 to 11 As shown, the child monitoring watch with water ingress alarm function and its usage method include a watch body 1, a positioning module 11, a processing module 12, an alarm module 13, and a water ingress detection module 14. The watch body 1, as the main structure worn by the child, carries the positioning module 11, processing module 12, alarm module 13, water ingress detection module 14, and communication module 15. The positioning module 11 is connected to the watch body 1 and is used to obtain the watch's location information. The watch's location information can be the current geographical location of the watch body 1, such as latitude and longitude, real-time positioning point, or other data that can characterize the location of the watch body 1. The processing module 12 receives the watch's location information obtained by the positioning module 11. The processing module 12 is connected to a database 121, which includes water area location information. The water area location information can include the boundary location information, center location information, outline range information, or surrounding preset buffer area information of water bodies such as rivers, lakes, reservoirs, ponds, seashores, and swimming pools. The processing module 12 calculates the distance between the watch body 1 and the water area location information based on the watch's location information and the water area location information, and activates the water ingress detection module 14 when the distance is less than a preset threshold. The water-drop detection module 14 identifies whether the watch body 1 is in water when it is activated, and stops water-drop detection when it is not activated. The alarm module 13 receives the identification signal output by the water-drop detection module 14 and alarms when the watch body 1 is in water.

[0022] In actual use, the child wears the watch body 1 during daily activities. The positioning module 11 continuously or intermittently acquires the watch's location information and sends it to the processing module 12. The processing module 12 reads the water area location information from the database 121 and matches the watch's location information with the water area boundary location information, outline range information, or preset buffer area information in the database 121. Specifically, the processing module 12 can calculate the distance between the real-time positioning point of the watch body 1 and the nearest water area boundary, or it can determine whether the real-time positioning point has fallen into the preset buffer area around the water area. If the real-time positioning point is outside the water area buffer area, or the distance between the watch body 1 and the nearest water area boundary is not less than a preset threshold, the processing module 12 determines that the child has not entered the water risk area, and the water fall detection module 14 remains in an inactive state. At this time, the internal mechanical parts of the water-falling recognition module 14 are also in a non-working state. The electromagnet 1494 maintains its attraction to the annular tube 1492, the annular tube 1492 remains in a blocked position, and the opening 1496 of the annular tube is not connected to the discharge hole 1411 of the first housing and the water inlet hole 1491 of the third housing. The sealing plate 144 restricts the position of the lever 142, and even if the eccentric wheel 145 is subjected to slight daily shaking, it will not drive the lever 142 to form an effective discharge action through the sleeve 143. If the processing module 12 determines that the distance between the watch body 1 and the water area is less than a preset threshold, the water-falling recognition module 14 is activated, and the water-falling recognition module 14 enters the waiting recognition state. At this time, the watch body 1 only enters the recognition preparation stage after approaching the water area, and does not directly determine that the child has fallen into the water, nor does it directly release dye; only after the water-falling recognition module 14 further recognizes that the watch body 1 is in the water and generates a recognition signal will the alarm module 13 execute an alarm based on the recognition signal.

[0023] In this embodiment, the processing module 12 generates a first warning signal when the distance between the watch body 1 and the water location information is less than a preset threshold, and the alarm module 13 outputs a first alert based on the first warning signal. The first warning signal is generated by the processing module 12 based on the location distance judgment result, indicating that the watch body 1 has entered a preset risk range near the water. The first alert is used to remind the child before they fall into the water, and is an early warning for the approaching water stage, which is different from the alarm after the water fall detection module 14 confirms that the watch body 1 is in the water.

[0024] In actual use, the processing module 12 calculates the distance based on the watch location information obtained by the positioning module 11 and the water area location information in the database 121. This distance can be the shortest distance from the real-time positioning point of the watch body 1 to the boundary of the water area, or it can be the distance from the real-time positioning point of the watch body 1 to the outer edge of the preset water area or the boundary of the buffer zone. When the calculated distance is less than the preset threshold, the processing module 12 generates a first warning signal. After receiving the first warning signal, the alarm module 13 outputs a first prompt to indicate that the child has approached the water area. During this stage, the water-falling recognition module 14 can enter the waiting state, but the dye discharge structure in the water-falling recognition module 14 still does not perform the discharge action. Specifically, the electromagnet 1494 continues to attract the annular tube 1492, the annular tube 1492 is still in the blocked position, the annular tube opening 1496 is not connected to the first housing discharge hole 1411 and the third housing water inlet hole 1491, the sealing plate 144 continues to restrict the lever 142, and the eccentric wheel 145 and the sleeve 143 do not drive the lever 142 to discharge the dye. This separates the "near water warning" from the "confirmed fall into water alarm," preventing children from accidentally triggering the dye discharge or a second alarm simply by approaching the water.

[0025] In this embodiment, the first alert is a vibration alert. The alarm module 13 includes a vibration motor 131, which generates vibration based on the first warning signal. The vibration motor 131 is located inside the watch body 1, and the vibration generated by the vibration motor 131 can be transmitted to the child's wrist through the watch body 1. The first alert is a vibration alert, which can prevent children from missing the alert information when they have not looked at the display interface or when the ambient noise is loud, making it suitable for children's outdoor activities and scenarios near water.

[0026] In actual use, after the processing module 12 generates the first warning signal, the alarm module 13 controls the vibration motor 131 to start. The vibration motor 131 drives the watch body 1 to vibrate, and the child can sense the vibration through their wrist and realize that they are approaching water. At this time, the vibration motor 131 is performing the first stage of warning reminder, and does not mean that the water identification module 14 has confirmed that the watch body 1 is in the water. The corresponding mechanical parts remain in a restricted state: the electromagnet 1494 remains energized and attracts the annular tube 1492, the annular tube 1492 does not rotate effectively, the opening 1496 of the annular tube is not connected to the discharge hole 1411 of the first housing and the water inlet hole 1491 of the third housing, the sealing plate 144 continues to restrict the lever 142, and the eccentric wheel 145 will not drive the lever 142 to discharge material through the sleeve 143 even if it is affected by the normal swing of the child's wrist. Through this setting, the first reminder can remind the child to stay away from the water in a tactile way, while avoiding the direct discharge action of the water identification module 14 when approaching the water.

[0027] In this embodiment, the child monitoring watch also includes a communication module 15, which is used to send a first warning alarm message to the monitoring terminal 2 when the processing module 12 generates a first warning signal. The monitoring terminal 2 can be a guardian's mobile phone, a monitoring terminal APP, or a monitoring platform. The first warning alarm message may include one or more of the following: watch location information, proximity to water warning information, and trigger time information, used to notify the guardian that the child has entered a preset risk range near water.

[0028] In actual use, when the processing module 12 determines that the distance between the watch body 1 and the water area location information is less than a preset threshold, the processing module 12 generates a first warning signal. On the one hand, the alarm module 13 can output a first prompt based on the first warning signal; on the other hand, the communication module 15 sends the first warning alarm information to the monitoring terminal 2. After the guardian learns through the monitoring terminal 2 that the child has approached the water area, they can promptly check the child's location, provide voice reminders, or intervene on-site. The first warning alarm information sent at this stage is for the approaching water area stage, not the second alarm information after confirming the fall into the water. At this time, the discharge execution structure in the water identification module 14 still does not discharge the dye, the electromagnet 1494 is not de-energized due to simply sending the first warning alarm information, the annular tube 1492 is still attracted and fixed, the notch 1493 and the annular tube opening 1496 still maintain the initial blocking correspondence state, no discharge connection path is formed between the first housing discharge hole 1411 and the third housing water inlet hole 1491, and the lever 142 and the eccentric wheel 145 are still in the non-discharge state. This allows for simultaneous vibration alerts on the child's end and remote alerts on the monitoring end, while avoiding accidental triggering of the mechanical material discharge structure.

[0029] In this embodiment, the communication module 15 is also used to receive control commands sent by the monitoring terminal 2, and the processing module 12 is used to control the first prompt to stop or maintain according to the control commands. The control commands are used to manage the first prompt during the approach to water phase. When the guardian is already near the child and confirms that the current scene is under control, they can send a control command through the monitoring terminal 2 to make the processing module 12 control the first prompt to stop; if the guardian believes that the risk still exists, they can also maintain the first prompt.

[0030] In actual use, after receiving the first warning alarm information, the monitoring terminal 2 sends a control command to the communication module 15 according to the situation on site. The communication module 15 receives the control command and passes it to the processing module 12. If the control command is used to stop the first warning, the processing module 12 controls the alarm module 13 to stop the first warning, for example, to stop the vibration motor 131 from vibrating; if the control command is used to maintain the first warning, the processing module 12 controls the alarm module 13 to continue outputting the first warning. This control command only changes the output state of the first warning and does not directly change the identification state of the water-falling recognition module 14 based on its position. That is, even if the first warning stops, as long as the processing module 12 continues to determine that the watch body 1 is still near the water, the water-falling recognition module 14 can still remain in the activated or identification state. In this state, the electromagnet 1494 remains attracted and fixed to the annular tube 1492, the annular tube 1492 does not open the discharge channel, the annular tube opening 1496 is not connected to the first housing discharge hole 1411 and the third housing water inlet hole 1491, the sealing plate 144 still restricts the lever 142, and the eccentric wheel 145 does not perform an effective discharge action. This avoids the first warning affecting wear for a long time, and also prevents the water-drop recognition safety logic from failing due to the removal of vibration.

[0031] In this embodiment, the processing module 12 is used to continue determining whether to activate the water-fall detection module 14 based on the watch's location information and the water area location information after the first prompt stops. This setting is used to distinguish between "first prompt stops" and "water-fall detection module 14 is off". Whether the first prompt stops is determined by the control command sent by the monitoring terminal 2, while whether the water-fall detection module 14 is activated is still determined by the distance between the watch body 1 and the water area location information.

[0032] In actual use, after the guardian sends a control command through the monitoring terminal 2 to stop the first prompt, the processing module 12 continues to receive the watch location information obtained by the positioning module 11 and continues to call the water area location information in the database 121 for distance judgment. If the distance from the real-time positioning point to the water area boundary is still less than the preset threshold, or if the real-time positioning point is still within the preset buffer area around the water area, the processing module 12 continues to keep the water fall recognition module 14 in the start or waiting recognition state; if the real-time positioning point has moved away from the water area and the distance is no longer less than the preset threshold, the processing module 12 can make the water fall recognition module 14 stop water fall recognition. During this process, if the water fall recognition module 14 is only in the waiting recognition state after approaching the water area and no water entry trigger occurs, the electromagnet 1494 still holds the annular tube 1492, and the annular tube 1492 still blocks the discharge channel; if the watch body 1 is actually in the water and enters the water entry trigger process, the electromagnet 1494 is de-energized, causing the annular tube 1492 to release the adsorption fixation and rotate under water pressure. This ensures that after the first prompt is canceled, the system still determines whether to retain the water fall recognition capability based on the real-time position.

[0033] In this embodiment, the water-drop detection module 14 is configured to acquire watch movement data and control dye discharge based on the watch movement data to form a visual positioning mark when the watch body 1 is submerged in water. As a specific embodiment, the water-drop detection module 14 includes a first housing 141, a first housing discharge hole 1411, a lever 142, a sleeve 143, a sealing plate 144, an eccentric wheel 145, a second housing 146, a ratchet 147, a pawl 148, a third housing 149, a third housing water inlet 1491, an annular tube 1492, a notch 1493, an electromagnet 1494, a Hall sensor 1495, an annular tube opening 1496, and a disassembly assembly 3. The first housing 141 forms the main housing space of the water-drop detection module 14. The first housing 141 contains the lever 142, a portion of the sleeve 143, the sealing plate 144, and the dye. The lever 142 has a semi-circular design, with one end located on one side of the sealing plate 144 and the other end corresponding to the dye accumulation area. The sealing plate 144 is used to restrict the position of the lever 142 when not in operation, and also to block the dye, preventing the dye from being accidentally discharged during daily wear. The sleeve 143 is connected to the lever 142 and extends from the inside of the first housing 141 to the outside of the first housing 141. The eccentric wheel 145 is located outside the sleeve 143. When a child's hand moves or the watch body 1 shakes, the eccentric wheel 145 can drive the sleeve 143 to rotate, and the sleeve 143 further drives the lever 142 inside the first housing 141 to rotate, thereby causing the lever 142 to push the dye.

[0034] In actual use, when the watch body 1 is in daily wear, the water-drop detection module 14 does not perform the discharge action. The dye in the first housing 141 is restricted by the blocking state of the sealing plate 144 and the annular tube 1492. The lever 142 is restricted to the initial position by the sealing plate 144. Even if the eccentric wheel 145 is slightly shaken by normal activities, it will not drive the lever 142 to effectively push the dye. The third housing 149 is set on the outer wall of the first housing 141. The water inlet 1491 of the third housing corresponds to the discharge hole 1411 of the first housing. The annular tube 1492 is set inside the third housing 149. The annular tube 1492 is provided with a notch 1493 and an annular tube opening 1496. The notch 1493 is used to make the annular tube 1492 form a non-complete annular structure and cooperate with the initial blocking position. The annular tube opening 1496 is used to connect the water inlet 1491 of the third housing and the discharge hole 1411 of the first housing after the annular tube 1492 is rotated to the preset opening position. Under normal conditions, the electromagnet 1494 attracts the annular tube 1492, keeping the annular tube 1492 fixed. The opening 1496 of the annular tube is misaligned with the water inlet 1491 of the third housing and the discharge hole 1411 of the first housing, with the water inlet 1491 of the third housing and the discharge hole 1411 of the first housing blocked by the wall of the annular tube 1492. When entering the vicinity of water, the processing module 12 activates the water-fall detection module 14, but does not immediately de-energize the electromagnet 1494; only after the water-fall detection module 14 enters the water-entry triggering process is the electromagnet 1494 de-energized, and the annular tube 1492 released from its attraction and fixation. When the watch body 1 is actually in water, the external water body exerts water pressure on the annular tube 1492 through the water inlet 1491 of the third housing, pushing the annular tube 1492 to rotate clockwise. When the opening 1496 of the annular tube is connected to the water inlet 1491 of the third housing and the discharge hole 1411 of the first housing, a dye discharge channel is formed. Subsequently, the child's hand sways left and right in the water, causing the eccentric wheel 145 to rotate. This rotation, through the sleeve 143, drives the paddle 142 to rotate. The paddle 142 pushes the dye accumulated inside the first housing 141, which is then discharged into the external water body through the discharge hole 1411 of the first housing, the annular pipe opening 1496, and the water inlet hole 1491 of the third housing, forming a visual positioning mark.

[0035] In this embodiment, the water-drop detection module 14 is used to determine the dye discharge status based on the watch's motion data. The dye discharge status includes a stopped discharge status, an intermittent discharge status, or a continuous discharge status. The watch's motion data can be reflected by the rotation status of the eccentric wheel 145, which includes rotation angle, rotation frequency, or rotation duration. The second housing 146 is located at the position where the sleeve 143 extends to the outside of the first housing 141. The eccentric wheel 145 is connected to the sleeve 143, and a ratchet 147 is provided on the eccentric wheel 145. A pawl 148 is provided inside the second housing 146. The ratchet 147 and the pawl 148 cooperate to limit the eccentric wheel 145 to rotate unidirectionally in a preset direction. The disassembly assembly 3 includes a slot 31 and a buckle 32. The slot 31 is equidistantly opened on the second housing 146, and the buckle 32 is connected to the watch body 1 at the position corresponding to the slot 31. The buckle 32 and the slot 31 engage, allowing the mechanical part of the water-drop detection module 14 to be detachably connected to the watch body 1.

[0036] In actual use, when the watch body 1 is far from water or the water-drop detection module 14 is not in an effective working state, the electromagnet 1494 attracts the annular tube 1492, the annular tube 1492 blocks the discharge channel, the sealing plate 144 restricts the lever 142, and the eccentric wheel 145 will not form an effective discharge drive, so the dye discharge state is a stopped discharge state. When the watch body 1 is in water and the child's hand is intermittently shaken, the eccentric wheel 145 rotates intermittently under the shaking action. The ratchet 147 and the pawl 148 cause the eccentric wheel 145 to rotate only clockwise. The eccentric wheel 145 drives the lever 142 to intermittently push the dye through the sleeve 143, so that the dye is discharged in an intermittent manner. At this time, the dye discharge state is an intermittent discharge state. When a child is struggling in the water or the watch body 1 is continuously shaken by the continuous water flow and limb movement, the eccentric wheel 145 rotates continuously or nearly continuously in a clockwise direction. The sleeve 143 continuously drives the lever 142 to move, and the lever 142 continuously pushes the dye out. At this time, the dye is continuously discharged. The ratchet 147 and pawl 148 restrict the eccentric wheel 145 from reversing, which can prevent the lever 142 from reversing and causing the dye to revert or the discharge to be interrupted. After the water-drop recognition module 14 completes one recognition and discharge, the user can release the latch 32 from the slot 31, remove the mechanical parts, including the second housing 146, from the watch body 1, and replace the mechanical parts of the water-drop recognition module 14 with a new one. This avoids disassembling the positioning module 11, processing module 12, alarm module 13, and communication module 15, improving maintenance convenience.

[0037] In this embodiment, the alarm module 13 outputs a second alarm signal after receiving the identification signal, and the communication module 15 sends a second alarm message to the monitoring terminal 2. The second alarm message includes the watch's location information. The second alarm signal is different from the first alert during the near-water phase. The second alarm signal corresponds to the alarm state after the water-falling identification module 14 has identified that the watch body 1 is in water or has generated a valid water-falling identification action. The Hall sensor 1495 is disposed inside the watch body 1 and is arranged corresponding to the rotation path of the eccentric wheel 145. The Hall sensor 1495 outputs an identification signal when the eccentric wheel 145 rotates to a preset sensing position. The Hall sensor 1495 generates the identification signal by sensing the rotation position of the eccentric wheel 145 or the sensing state in cooperation with the eccentric wheel 145, without needing to have direct contact with the eccentric wheel 145.

[0038] In actual use, after the watch body 1 falls into water, the water immersion recognition module 14 enters the effective recognition process. Upon water immersion trigger, the electromagnet 1494 is de-energized, the annular tube 1492 releases its adsorption and rotates clockwise under water pressure, connecting the annular tube opening 1496 with the third housing water inlet 1491 and the first housing discharge hole 1411, opening the discharge channel. The child's hand movement causes the eccentric wheel 145 to rotate, and the eccentric wheel 145, through the sleeve 143, drives the paddle 142 to push the dye out. Simultaneously, the eccentric wheel 145 rotates unidirectionally clockwise with the cooperation of the ratchet 147 and pawl 148. When the eccentric wheel 145 rotates to the preset sensing position, the Hall sensor 1495 senses this state and outputs a recognition signal. After receiving the recognition signal, the alarm module 13 outputs a second alarm signal, and the communication module 15 simultaneously sends a second alarm message to the monitoring terminal 2. The second alarm message includes the watch's location information, allowing the guardian to know the child's location. This second alarm process is based on the identification signal already generated by the water-falling identification module 14. It goes a step further than simply being near water for early warning and can be used for alarm and location notification after actual water fall.

[0039] In this embodiment, the method of using the child monitoring watch with water-fall detection function is applied to the child monitoring watch according to any one of claims 1 to 9. The method includes: acquiring watch location information through positioning module 11; processing module 12 receiving watch location information and calculating the distance between watch body 1 and water location information based on watch location information and water location information in database 121; when the distance is less than a preset threshold, processing module 12 activates water fall detection module 14 and generates a first warning signal; alarm module 13 outputs a first prompt based on the first warning signal, or communication module 15 sends a first warning alarm message to monitoring terminal 2; communication module 15 receives control instructions sent by monitoring terminal 2, processing module 12 controls the first prompt to stop or remain based on the control instructions, and continues to determine whether to activate water fall detection module 14 based on watch location information and water location information; water fall detection module 14 identifies whether watch body 1 is in water when activated, and generates an identification signal when watch body 1 is in water; alarm module 13 receives the identification signal and outputs a second alarm signal, communication module 15 sends a second alarm message to monitoring terminal 2; water fall detection module 14 acquires watch motion data and controls dye discharge based on watch motion data to form a visual positioning mark when watch body 1 is in water.

[0040] In actual use, after a child wears the watch body 1, the positioning module 11 first obtains the watch's location information. The processing module 12 then determines whether the child is near the water based on the watch's location information and the water location information in the database 121. If the child is not near the water, the water-falling detection module 14 remains inactive. The electromagnet 1494 attracts the annular tube 1492, which blocks the discharge channel. The sealing plate 144 restricts the lever 142, and the eccentric wheel 145 does not perform an effective discharge action. If the child is near the water, the processing module 12 activates the water-falling detection module 14 and generates a first warning signal. The alarm module 13 outputs a first alert, and the communication module 15 sends the first warning alarm information to the monitoring terminal 2. The guardian can send control commands through the monitoring terminal 2 to stop or maintain the first alert, but the processing module 12 continues to determine whether to activate the water-falling detection module 14 based on the watch's location information and the water location information. If the child subsequently falls into the water, the water ingress detection module 14 will enter effective detection: before the water ingress trigger, the electromagnet 1494 will still maintain its attraction to the annular tube 1492, and the discharge channel will be closed; after the water ingress trigger, the electromagnet 1494 will be de-energized, and the annular tube 1492 will rotate clockwise under the action of water pressure, so that the opening 1496 of the annular tube is connected to the water inlet 1491 of the third housing and the discharge hole 1411 of the first housing; the child's hand shaking will cause the eccentric wheel 145 to rotate clockwise in one direction, and the eccentric wheel 145 will drive the paddle 142 through the sleeve 143 to push the dye out; when the eccentric wheel 145 rotates to the preset sensing position of the Hall sensor 1495, the Hall sensor 1495 will output a recognition signal, the alarm module 13 will output a second alarm signal, and the communication module 15 will send a second alarm message including the watch's location information to the monitoring terminal 2. After completing one water immersion detection and dye discharge, the clip 32 in the disassembly assembly 3 can disengage from the slot 31, allowing the mechanical part of the water immersion detection module 14 to be removed from the watch body 1 and replaced. This method enables early warning when approaching water, mechanical identification after water immersion, visual location of the dye, remote alarm notification, and rapid replacement after triggering.

[0041] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
