Description

Technical Field

[0001] This invention relates to the field of personal safety monitoring technology, and in particular to a new personal safety monitoring device and its application method. Background Technology

[0002] Due to reasons such as children's work and studies, differences in living habits with children, and the passing of a spouse, there are a large number of empty-nest elderly people in society. If an empty-nest elderly person falls at home due to health reasons and cannot contact family members who are not at home via mobile phone, there is a risk that the fall may not receive timely assistance and the condition may worsen (for example, falling in the bathroom due to a slippery floor, or an elderly person with high blood pressure falling due to straining during bowel movements, causing a ruptured blood vessel in the brain).

[0003] In the existing technology, corresponding alarm mechanisms have emerged, which to some extent reduce the problem of empty-nest elderly not being able to get timely help when accidents occur. The current alarm mechanisms generally include the following types: (1) Active distress alarm (also known as telephone caller, which has a function to store up to six family members' phone numbers to be contacted before use). In application, when the elderly (not limited to the elderly) feel unwell, they can manually press the emergency button of the alarm, and the alarm will actively call one or more relatives at the remote end of the elderly (after dialing for a period of time, the alarm will automatically stop dialing and return to the initial state). The remote family members can rush home in time or notify other relatives nearby, community property management, etc. to provide timely rescue. This type of alarm can only realize the alarm function by the elderly manually operating the emergency button (and does not have the function of monitoring the safety of the elderly entering the bathroom and toilet). When the user falls suddenly at a certain distance from the alarm, the emergency button cannot be operated (even if the emergency button is wirelessly controlled, it cannot be guaranteed that the button can be pressed effectively when the elderly fall and cannot move). Therefore, it cannot be guaranteed that family members can still be contacted when falling, and its application has a major defect. (2) Video data analysis-based alarm: In this application, the camera collects images of the elderly’s activities at home. When the elderly person falls or has other abnormalities, the internal software unit analyzes and judges the data and then actively calls one or more relatives of the elderly person at a distance. Although this type of alarm does not require the elderly person to approach the alarm to operate the corresponding emergency button, the range of the image data collected by the camera is limited. It is impossible to install cameras in every room of the house. In particular, considering privacy issues, it is even more impossible to install cameras in bathrooms and toilets (if installed in the bathroom, the water vapor generated by showering will also prevent effective video collection; if installed in the toilet, the relevant software will not be able to distinguish whether the elderly person has fallen when squatting down to urinate or defecate). Therefore, its application range is relatively limited and it cannot achieve the effect of monitoring the safety of the elderly around the clock without blind spots. (3) Alarms based on millimeter-wave radar data analysis. These alarms solve the privacy problem to some extent. However, due to functional limitations, they cannot be effectively applied in bathrooms (bathroom water vapor will continuously absorb some of the energy of the millimeter-wave radar, causing signal attenuation, with a typical attenuation rate of 5~10 dB / km; it will also cause Rayleigh scattering and Mie scattering of millimeter-wave radar, causing some echo energy to deviate from the original path and reduce the target reflection intensity). They cannot determine whether the elderly have fallen when squatting down in the bathroom. Therefore, their application scope is relatively limited and cannot achieve the effect of monitoring the safety of the elderly around the clock without blind spots. (4) Alarms based on wearable devices. These alarms require the relevant alarm mechanism to be worn by the elderly, which will cause inconvenience to the elderly. Moreover, they cannot serve as a safety reminder when the elderly forget to wear them.Furthermore, none of the aforementioned alarm systems can actively monitor whether an accident has occurred while the elderly are asleep or indoors without detection mechanisms, nor can they monitor the safety of the elderly after they leave home (e.g., if an elderly person has an accident while out for a walk or shopping and does not return home). In reality, many falls at home occur in the bathroom or toilet (referred to as the bathroom throughout this article). Data from my country's disease surveillance system shows that approximately 50%–56% of home falls occur in the bathroom, covering the entire process of bathing and using the toilet. Specifically, about one-third of fractures in the elderly occur during toileting, with weakness in the lower limbs upon standing and lack of support being key contributing factors. Risk factors include: orthostatic hypotension caused by squatting and standing, cardiovascular events induced by straining during bowel movements, and lack of assistive devices (handrails / increased seats). The main reasons for this are: slippery floors leading to falls, sudden changes in water temperature causing blood pressure fluctuations, and steam-induced hypoxia and fainting (the main mechanisms are these). Therefore, it is very necessary to provide a personal safety monitoring device and its application method that not only has an active alarm function for the elderly, but also can monitor their safety in places such as bathrooms and toilets, including falls, and can also promptly notify family members to provide assistance if the elderly are not at home during a certain time period, in a location they pass through every day, or if they do not return home after leaving home at a certain time, indicating that the elderly may have experienced accidents at home or outside, including falls (including unconsciousness during sleep). Summary of the Invention

[0004] To overcome the shortcomings of existing home personal safety monitoring devices, which are limited by technology and have the drawbacks described in the background art, this invention provides a personal safety monitoring device and application method that does not require the installation of probes in every indoor area, has good privacy protection, and, with the joint action of relevant institutions, not only has the functions of active alarm for the elderly and alarm for combustible gas leaks in the home, but also can monitor the safety of the elderly when they enter private places such as bathrooms and toilets, including falls. It can also promptly notify family members to provide assistance if the elderly fall while showering or using the toilet, or if they are not present in their usual daily locations (such as the kitchen, living room, or bathroom) within a certain time period (including after normal sleep), or if they do not return home after leaving home for a certain period of time, indicating that the elderly may have experienced an accident at any location in the home or outside, such as a fall or sudden illness and unconsciousness during sleep. This reduces the risk of more serious consequences due to delayed rescue.

[0005] The technical solution adopted by this invention to solve its technical problem is: A personal safety monitoring device includes a wireless transmitting circuit module, a telephone caller, and also has a timing circuit, a combustible gas leak detection circuit, a timing detection circuit, a trigger circuit, and a wireless receiving circuit. The telephone caller, timing circuit, combustible gas leak detection circuit, trigger circuit, and wireless receiving circuit are fixedly installed in a component box, which is installed indoors. The power output terminal of the trigger circuit and the power input terminal of the timing circuit are electrically connected. The signal output terminals of the combustible gas leak detection circuit, wireless receiving circuit, and timing circuit are electrically connected to two contacts below the dial button of the telephone caller. The timing detection circuit is equipped with a reed switch and a magnet. The reed switch is installed inside a housing. The housing is fixedly installed on a door leaf, and the magnet is fixedly installed on a door frame. An application method of the personal safety monitoring device includes the following steps: S1: When the user experiences discomfort, they manually press the emergency button on the telephone caller or the transmit button on the wireless transmitting circuit module, and the telephone caller actively dials a remote number; S2: When a combustible gas leak occurs in the home, the combustible gas leak detection circuit triggers an on-site alarm and dials a remote number via the telephone caller; S3: The timing circuit automatically calls the remote person if the user does not pass the corresponding location within the set time, indicating an accident at home or outside. If the user passes the corresponding location before the set time period, indicating no accident at home or outside, no call is made. S4: If the user enters a specific room and closes the door for more than the set time without leaving, indicating an accident at home, the phone pager automatically calls the remote person. If the user leaves before the set time period, indicating no accident at home, no call is made.

[0006] Furthermore, the outer casing and component box can be installed magnetically; the moving and stationary contacts inside the reed switch are normally open.

[0007] Furthermore, the timing circuit includes a relay and a timing module that are electrically connected. The negative power input terminal of the timing module is connected to the trigger signal input terminal, the power output terminal of the timing module is connected to the negative power input terminal of the relay, and the positive power input terminal of the timing module is connected to the control power input terminal of the relay.

[0008] Furthermore, the wireless receiving circuit includes a wireless receiving circuit module and a relay that are electrically connected. The positive power input terminal of the relay is connected to the power output terminal of the wireless receiving circuit module, and the negative power input terminal of the relay is connected to the negative power input terminal of the wireless receiving circuit module.

[0009] Furthermore, the combustible gas leak detection circuit includes a combustible gas leak detector and a relay and an alarm that are electrically connected. The positive power input terminal of the relay and the alarm is connected to the power output terminal of the combustible gas leak detector, and the negative power input terminal of the relay and the alarm is connected to the negative power input terminal of the combustible gas leak detector.

[0010] Furthermore, the triggering circuit includes a pyroelectric detection module and a relay that are electrically connected. The power output terminal of the pyroelectric detection module is connected to the positive power input terminal of the relay, and the negative power input terminal of the pyroelectric detection module is connected to the negative power input terminal of the relay.

[0011] Furthermore, the timing detection circuit includes an electrically connected timing module, a wireless transmission circuit module A, a charging indication sub-circuit, and a power switch. The timing module, wireless transmission circuit module A, charging indication sub-circuit, power switch, and reed switch are installed together in the housing. One end of the reed switch is connected to one end of the power switch, the positive power input terminal of the wireless transmission circuit module A, and the positive power input terminal of the charging sub-circuit. The other end of the reed switch is connected to the other end of the power switch and the positive power input terminal of the timing module. The negative power input terminal and signal input terminal of the timing module are connected to the negative power input terminal of the charging sub-circuit. The power output terminal of the timing module is connected to the negative power input terminal of the wireless transmission circuit module A.

[0012] Furthermore, in the wireless transmission circuit module of the timing detection circuit, two contacts under one of the transmission buttons are electrically connected together.

[0013] Furthermore, the reed switch is located at one end of the inner side of the component box. After the door is closed, the magnetic force of the magnet acts on the reed switch, and the internal contacts of the reed switch close.

[0014] Furthermore, the charging sub-circuit of the timing detection circuit includes an adjustable resistor, a resistor, a transistor, and a light-emitting diode that are electrically connected. One end of the adjustable resistor is connected to one end of the first resistor and the positive terminal of the light-emitting diode. The other end of the adjustable resistor is connected to the base of the first transistor and one end of the second resistor. The collector of the first transistor is connected to the other end of the first resistor and the base of the second transistor. The collector of the second transistor is connected to one end of the third resistor. The other end of the third resistor is connected to the negative terminal of the light-emitting diode. The other end of the second resistor is connected to the emitters of both transistors.

[0015] Compared with existing technologies, the advantages of this invention are: It eliminates the need to install sensors in every indoor area, providing excellent privacy protection. The elderly can press the emergency button on the call button to remotely trigger an alarm. Due to its wireless transmission circuit, the elderly can control the call button from any location indoors, offering convenience. In the event of a flammable gas leak at home, it can not only provide on-site alarm but also promptly notify family members remotely via telephone. In particular, this invention can also monitor the safety of the elderly when they enter private areas such as bathrooms and toilets, including situations involving falls. If an elderly person falls while showering or using the toilet, or if they are not present in their usual daily routine (such as the kitchen, living room, or bathroom) within a certain timeframe (including after normal sleep), or if they do not return home after a certain period, it indicates a possible accident at home or outside, including falls, sudden illness during sleep, or unconsciousness. This allows for timely telephone alerts to family members to provide assistance, reducing the risk of more serious consequences due to delayed rescue. In summary, this invention has promising application prospects. Attached Figure Description

The component box 6 is fixed to the wall of an indoor passageway that people frequently pass through (e.g., an area with a high frequency of traffic flow). On the wall before entering the bathroom, living room, and kitchen (in this embodiment, it is installed on the wall before entering the bathroom), the height of component box 6 is lower than the height of a person (the probe of the pyroelectric detection module of the trigger circuit faces the passageway on the other side of the wall); there are two sets of the timing detection circuit 3 (not limited to two sets, one set is used for one bathroom and shower room, and multiple sets are used for multiple bathrooms and shower rooms; in this embodiment, two sets are installed). Each set of timing detection circuit is equipped with a reed switch GH and a permanent magnet block CT. The reed switch GH is installed on the circuit board inside the outer casing 31; the outer casing 31 is fixedly installed on the door leaf or door frame of the bathroom or shower room by adhesive or bolts (in this embodiment, it is installed on the left front side of the door leaf), and the magnet block CT is fixedly installed on the door frame or door leaf of the bathroom or shower room by adhesive or bolts (in this embodiment, it is installed on the right end of the left front side of the door frame).

[0024] Figure 1 , 2As shown in Figures 3, 4, and 5, a magnetic sheet or metal sheet can be installed on the rear side of the outer casing 31. A corresponding metal sheet or magnetic sheet is installed on the door frame or door leaf, and the outer casing 31 and the corresponding door frame or door leaf are attracted together by the magnetic sheet and metal sheet (making it convenient to remove the outer casing and then open the battery cover to take out the battery for charging). A magnetic sheet or metal sheet can also be installed on the rear side of the component box 6, and a corresponding metal sheet or magnetic sheet is installed on the wall. The component box and the wall are attracted together by the magnetic sheet and metal sheet. The moving and stationary contacts inside the reed switch GH are normally open. The wireless transmission circuit module T7 can also be installed inside the watch-shaped outer casing A, and can be worn on the wrist via a wristband (or carried on the body in any other way), making it convenient to press the transmit button of the wireless transmission circuit module T7 at any time. The timing circuit includes a relay J2 and a timing module T3 connected via circuit board wiring. The negative power input pin 2 of the timing module T3 is connected to the trigger signal input pin 3, and the negative power output pin 4 of the timing module T3 is connected to the negative power input pin of the relay J2.

The positive power input pin of the relay J4 is connected to the power output pin 3 of the wireless receiving circuit module T6, and the negative power input pin of the relay J4 is connected to the negative power input pin 2 of the wireless receiving circuit module T6. The combustible gas leak detection circuit includes a combustible gas leak detection module T2, a relay J1, and an alarm B connected via circuit board wiring. The positive power input terminals of relay J1 and alarm B are connected to pin 3 of the power output terminal of combustible gas leak detection module T2, and the negative power input terminals of relay J1 and alarm B are connected to pin 2 of the negative power input terminal of combustible gas leak detection module T2. The detection head of combustible gas leak detection module T2 is located outside the first opening at the front of component box 6 (for detecting external gas leaks). The triggering circuit includes a pyroelectric detection module T5 and a relay J3 connected via circuit board wiring. The positive power output terminal pin 3 of pyroelectric detection module T5 is connected to the positive power input terminal of relay J3, the negative power input terminal pin 2 of pyroelectric detection module T5 is connected to the negative power input terminal of relay J3, and the positive power input terminal pin 1 of pyroelectric detection module T5 is connected to the control power input terminal of relay J3. The detection head of pyroelectric detection module T5 is located outside the second opening at the front of component box 6 (for detecting people passing through indoor corridors).Each timing detection circuit includes a timing module T8, a wireless transmission circuit module AT9, a battery G1 (which can also use an AC-to-DC power supply module to power the reed switch, timing module, wireless transmission circuit module, etc.), a charging indication sub-circuit 32, and a power switch K1, all connected via circuit board wiring. The timing module T8, wireless transmission circuit module AT9, battery G1, charging indication sub-circuit 32, power switch K1, and reed switch GH are mounted together on the circuit board inside the housing 31. The reed switch GH is located on the left side inside the housing 31, and the moving contact is located on the right side of the left side inside the housing 31. The magnet CT is close to one side of the outer side of the housing 31 at a certain distance (2 mm). When the door is closed, the magnetic force of the magnet CT acts on the reed switch GH, and the internal contacts of the reed switch GH close (the reed switch GH and the magnet are on the same plane, about 3 mm apart). When the door is opened, the magnetic force of the magnet CT no longer acts on the reed switch GH, and the internal contacts of the reed switch GH open. The charging sub-circuit of the timing detection circuit includes an adjustable resistor RP, resistors R1, R2, R3, transistors Q1 and Q2, and a light-emitting diode VL connected via circuit board wiring. One end of the adjustable resistor RP is connected to one end of the first resistor R1 and the positive terminal of the light-emitting diode VL. The other end of the adjustable resistor RP is connected to the base of the first transistor Q1 and one end of the second resistor R3. The collector of the first transistor Q1 is connected to the other end of the first resistor R1 and the base of the second transistor Q2. The collector of the second transistor Q2 is connected to one end of the third resistor R2. The other end of the third resistor R2 is connected to the negative terminal of the light-emitting diode VL. The other end of the second resistor R3 is connected to the emitters of the two transistors Q1 and Q2. The light-emitting surface of the light-emitting diode VL is located outside the first opening at the front end of the housing 31. In the timing detection circuit, the positive terminal of the battery G1 is connected to one end of the reed switch GH, one end of the power switch K1, pin 1 of the positive power input terminal of the wireless transmitter circuit module AT9, and one end of the adjustable resistor RP of the charging sub-circuit.

Pin 2 of the negative power input terminal and pin 3 of the timing module T8 are connected to the negative terminal of the battery G1 and the emitters of the two transistors Q1 and Q2 of the charging sub-circuit. Pin 4 of the negative power output terminal of the timing module T8 is connected to pin 2 of the negative power input terminal of the wireless transmitter circuit module AT9. The two contacts under one of the transmit buttons S1 of the wireless transmitter circuit module AT9 are connected together by a wire. The handle of the power switch K1 is located outside the second opening at the front of the outer casing 31 (for the user to operate the power switch).

[0025] Figure 1 , 2As shown in Figures 3, 4, and 5, the power input terminals 1 and 2 of the regulated power supply T1 are connected to the two poles of the 220V AC power supply via wires. The power output terminals 3 and 4 of the power module T1 are connected to the power input terminals 1 and 2 of the telephone pager T4, the combustible gas leak detection module T2, the wireless receiving circuit module T6, and the pyroelectric detection module T3 of the trigger circuit via wires. The normally closed contact and negative power input terminal of the relay J3 at the power output terminal of the trigger circuit are connected to the power input terminals 1 and 2 of the timing module T3 of the timing circuit via wires. The control contact and normally open contact of the relay J1 at the signal output terminal of the gas detection circuit, the control contact and normally open contact of the relay J4 at the signal output terminal of the wireless receiving circuit, the control contact and normally open contact of the relay J2 at the signal output terminal of the timing circuit, and the two contacts below the emergency button SD of the telephone pager T4 via wires.

[0026] Figure 1 , 2As shown in Figures 3, 4, and 5, the application process of a personal safety monitoring device is as follows: After turning on the main power switch (after turning off the main power switch or unplugging the power plug of power module T1, the device will no longer monitor the elderly's daily activities), 220V AC power enters the power input terminal of power module T1. Pins 3 and 4 of power module T1 output a stable 5V DC power supply, which enters the power input terminals of the telephone pager T4, the combustible gas leak detection circuit, the wireless receiving circuit, and the trigger circuit. The above circuits then operate under power. This invention has an active alarm function similar to a regular telephone pager. Specifically... When an elderly person (not limited to the elderly) experiences discomfort, they can manually press the emergency button SD on the telephone call device T4. The telephone call device T4, under its own functional operation, can proactively dial one or more relatives remotely (after dialing for a period of time, the alarm automatically stops dialing and returns to its initial state). The remote family members can then promptly return home or notify other nearby relatives, community property management, etc., for timely assistance. In this invention, the elderly person can also manually press the first transmit button S1 of the wireless transmission circuit module T7 from any location indoors, at which point the wireless transmission circuit module T7 will transmit the first wireless closed signal. After receiving the first wireless closed signal, the wireless receiving circuit module T6 outputs a high level at pin 3, which enters the positive power input terminal of relay J4. Relay J4 is then energized, closing its control and normally open contacts. Since the control and normally open contacts of relay J4 are connected to the two contacts under the emergency button SD of the telephone pager T4, this is equivalent to a person pressing the emergency button SD. Under its own function, the telephone pager T4 can also actively make calls to one or more relatives of the elderly person remotely. Because the elderly person can wirelessly control the telephone pager alarm from any location indoors, it brings convenience to them. When there is no combustible gas leak in the home, pin 3 of the combustible gas leak detection module T2 does not output a high level, relay J1 will not be energized, and the pager T4 will not make calls to family members at a distance (at the same time, alarm B will not be energized). When a combustible gas leak occurs in the home and the leaking gas reaches the combustible gas leak detection module T2, pin 3 of the combustible gas leak detection module T2 outputs a high level, which enters the positive power input terminal of relay J1 and alarm B (alarm B is energized and sounds to alert elderly people in the home that there is a combustible gas leak and to be careful). As a result, relay J1 is energized and its control contact and normally open contact close. Since the control contact, normally open contact and the two contacts under the emergency button SD of pager T4 are connected respectively, this is equivalent to pressing the emergency button SD by hand. Under its own function, pager T4 will actively make calls to one or more relatives at a distance from the elderly person.

[0027] Figure 1 , 2As shown in Figures 3, 4, and 5, after the timing module T3 is powered on, under the action of its own circuit (the 5V power supply powers the power input pin 1 of the timing module T3 via the control contact and normally closed contact of relay J3), at certain intervals (the time is adjustable; specifically, before the first application, the installation technician or user should open the back cover of the component box and operate the corresponding button of the timing module T3 to adjust it according to the elderly person's usual nighttime sleep time (extend the time slightly to prevent false alarms). In this embodiment, it is adjusted to 9 hours. After the first adjustment, if the elderly person's corresponding habits do not change, no further adjustment is needed), the pin 3 of the timing module T3 outputs a high level to the positive power input terminal of relay J2. Thus, relay J2 is energized and its control contact and normally open contact close. Since the control contact, normally open contact, and two contacts under the emergency button SD of the telephone pager T4 are respectively connected, this is equivalent to a person pressing the emergency button SD. Under its own function, the telephone pager T4 will actively make a call to one or more relatives of the elderly person at a distance. In practice, during the 9-hour (not limited to 9-hour) accumulation period of the timing module T3, if the elderly person gets up at night or goes to the corresponding indoor area to do things (such as going to the toilet, cooking in the kitchen, etc.) and passes in front of the detector head of the pyroelectric detection module T5 (within a 70-degree fan-shaped area of ​​about two meters), the pyroelectric detection module T5 will output a high level from pin 3 under the action of its internal circuitry, which will enter the positive power input terminal of relay J3. Relay J3 will be energized and its control contact and normally closed contact will be open. In this way, the power input terminal of the timing module T3 will be de-energized, and the corresponding relay J2 will not be energized and will not be energized and will not be energized and will be closed. After the elderly person leaves the detection head area of ​​the pyroelectric detection module T5, pin 3 of the pyroelectric detection module T5 will stop outputting power to the positive power input terminal of relay J3. Relay J3 will be de-energized and its control contact and normally closed contact will close again. In this way, the power input terminal of the timing module T3 will be energized again and will start the next accumulation of time. Before the next 9-hour cumulative countdown expires, if the elderly person does not pass in front of the pyroelectric detection module T5 due to various unforeseen circumstances—that is, if the elderly person is not present in the corresponding location they pass through daily (such as the kitchen, living room, or bathroom) during the corresponding time period, or does not return home after leaving home for the corresponding time period (such as going out shopping)—the caller T4 will proactively make a call to one or more of the elderly person's relatives at a distance. Specifically, if the elderly person passes in front of the pyroelectric detection module T5 normally before the next cumulative countdown expires, the timing module T3 will restart the next 9-hour cumulative countdown (no call will be made before the countdown expires).As described above, if an elderly person returns home from home or elsewhere and passes through the corresponding locations within a normal timeframe (such as the kitchen and bathroom, which are routes the elderly person normally traverses several times a day), then the pager T4 will not make a call. However, if the elderly person experiences an accident at any location within the home or outside, such as a fall or sudden illness / coma during sleep, and has not passed through the corresponding location (in front of the probe head of the pyroelectric detection module T5) within the corresponding timeframe, the pager T4 will proactively call a family member remotely. It should be noted that although this invention detects accidents in other rooms of the home or outside the home through the timing module T3, and monitors whether the elderly person experiences a sudden illness / coma during sleep at intervals of several hours, it has significant practical value compared to existing technologies that cannot detect accidents in other rooms of the home without probes installed, or monitor whether the elderly person experiences a sudden illness / coma during sleep (some illnesses or falls resulting in fractures do not cause death or other serious consequences within a few hours).

[0028] Figure 1 , 2As shown in Figures 3, 4, and 5, when the elderly person does not enter the toilet or bathroom, the distance between the magnet CT and the reed switch GH is maintained, and the moving and stationary contacts inside the reed switch GH are open. Therefore, the wireless transmission circuit module AT9 will not transmit the first wireless closing signal. When the elderly person closes the door before entering the toilet or bathroom, the magnetic force of the magnet CT will act on the reed switch GH, causing the moving and stationary contacts inside the reed switch GH to close. In this way, the timing module T8 is powered on and starts working. After the timing module T8 is powered on, under the action of its own circuit, if the accumulated set time has not been reached on pin 4 (the time is adjustable; specifically, before the first use, the installation technician or user should open the back cover and operate the corresponding button of the timing module T8 to adjust it according to the time the elderly usually takes to enter the bathroom or toilet (extend it slightly beyond the normal time to prevent false alarms; after the first adjustment, if the elderly's habits do not change, no further adjustment is needed), for example, in this embodiment, the timing module T8 installed in front of the bathroom door has an accumulated time of 40 minutes, and the timing module T8 installed in front of the toilet door has an accumulated time of 20 minutes), then pin 4 of the corresponding timing module T8 will not output a low level. In this case, the wireless transmission circuit module AT9 will not transmit the first wireless closure signal, and the telephone pager T4 will not make a call to a family member at a distance. When an elderly person enters the bathroom or toilet and an accident occurs, and the door is not opened within a certain time, the timing module T8 will output a low level at pin 4 after the timer expires, which will then enter the negative power input terminal of the wireless transmission circuit module AT9. The wireless transmission circuit module AT9 will then be powered on. Since the two contacts under the first wireless signal transmitting button S1 of the wireless transmission circuit module AT9 are pre-connected (equivalent to a person pressing S1), the wireless transmission circuit module AT9 will then transmit the first wireless closed signal. After the wireless receiving circuit module T6 receives the first wireless closed signal, its pin 3 will output a high level, which will enter the positive power input terminal of the relay J4. The relay J4 will then be powered on and its control contact and normally open contact will close. Since the control contact, normally open contact, and two contacts under the emergency button SD of the telephone pager T4 are connected respectively, this is equivalent to a person pressing the emergency button SD. Under its own function, the telephone pager T4 can also actively make calls to one or more relatives of the elderly person remotely. As described above, if an elderly person enters the bathroom or toilet and an accident occurs, the telephone caller T4 will proactively and promptly dial a family member's mobile phone (achieving better timeliness compared to a timed alarm circuit). In this invention, if the elderly person does not have the habit of closing the bathroom or toilet door, they can turn on the power switch K1 before entering. The timer module T8 will then be powered on and will monitor the elderly person's safety inside the bathroom or toilet (the power switch K1 will be turned off after leaving the bathroom or toilet).

[0029] Figure 1 ,2 As shown in Figures 3, 4, and 5, when the battery G1 has sufficient charge (e.g., higher than 5V), the power output from the battery G1 is divided by the adjustable resistor RP and resistor R3 and enters the base voltage of transistor Q1, which is higher than 0.7V. Transistor Q1 conducts, and the collector outputs a low level that enters the base of transistor Q2. Transistor Q2 has no suitable forward bias voltage and is in the cutoff state. Therefore, the LED VL will not be energized and will light up, indicating that the battery G1 has sufficient charge and does not need to be charged temporarily. When the battery G1 is low on power (e.g., below 5V), the power output from battery G1 is divided by adjustable resistor RP and resistor R3 and enters the base voltage of transistor Q1, which is below 0.7V. Transistor Q1 is cut off, and its collector no longer outputs a low level to the base of transistor Q2. The base of transistor Q2 is given a suitable forward bias voltage through resistor R1 and is in a conducting state. Then, LED VL will be energized and light up to indicate that battery G1 is low on power and needs to be charged (resistor R2 reduces voltage and limits current). The user can then remove battery G1 for charging, ensuring stable and reliable operation of the equipment. (In actual use, when the door is not closed, the timing detection circuit is in a zero-power state. Even when the timing detection circuit is energized, its standby current is only about 1 mA. Therefore, under normal circumstances, battery G1 only needs to be charged once every six months, which is quite convenient.) Figure 4 , 5In this circuit, power module T1 is an AC 220V to DC 5V power module; relays J1, J2, J3, and J4 are DC 5V; wireless transmitting circuit modules T7, AT9, and T6 are wireless transmitting and receiving modules operating at a frequency of 433MHz, with a wireless signal transmission and reception range of 50 meters (two transmitters and one receiver); timing modules T3 and T8 are YYS-5V adjustable delay relay modules, each with two power input terminals (pins 1 and 2), one low-level start signal input terminal (pin 3, which is connected to pin 2), one low-level signal output terminal (pin 4), and five time setting switches. By operating these switches, the time interval between power outputs from the two power input terminals after power is received can be set (pin 4 can be set from 10 seconds to 24 hours). (Power is output after the sensor is activated). The pyroelectric detection module T5 is a small pyroelectric human infrared sensor module of model AM312. It has two power input terminals and one power output terminal. When there is a moving human signal in front of its detector head, the power output terminal will output power, and otherwise it will not output power. It has a detection distance adjustment knob. Adjusting to the left will shorten the detection distance, and adjusting to the right will lengthen the detection distance (maximum detection distance is 5 meters. In this embodiment, it is adjusted to about 2 meters). The reed switch GH is a normally open contact reed switch. The combustible gas detection module T2 is a combustible gas sensor of model MQ-7. It has two power input terminals and one power output terminal. When it is working, its detector head detects combustible gas. The power output terminal outputs power when the device is in use, and does not output power otherwise; the telephone pager T4 is model PA-207, which has an emergency button that can dial up to six phone numbers at once when pressed; the battery G1 is a 5V / 6Ah lithium battery (battery G is a 5V / 2Ah lithium battery); transistors Q1 and Q2 are model 9013 (NPN transistors); resistors R1, R2, and R3 have resistance values ​​of 100KΩ, 500Ω, and 7KΩ respectively; the adjustable resistor RP has a resistance value of 100KΩ (adjusted to 43KΩ in this embodiment); the LED VL is a red LED; the alarm B is a model SFM-27 active continuous audible buzzer alarm. All of the above electronic components are existing mature products, and their working principles will not be described in detail in this application.

[0030] Figure 1 , 2 As shown in Figures 3, 4, and 5, in this invention, the power output terminal of the timing module T8 of the timing detection circuit can also be directly connected to a relay via a wire. The relay control contact terminal and normally open contact terminal are connected to the two contacts under the emergency button SD of the telephone caller T4 via wires.

[0031] It is particularly important to note that various types of detectors, such as photoelectric reflective detectors, photoelectric through-beam switches, proximity switches, pyroelectric detection modules, radar human body detection modules, microwave detection modules, ultrasonic detectors, and mechanical contact switches (e.g., door closing switches with closed contacts and door opening switches with open contacts), are used to detect human entry into indoor areas (e.g., bathrooms, toilets, etc.). These detectors are then combined with relevant circuits and any timer to accumulate the timer readings. Upon completion of the timer, a wired or wireless alarm (e.g., telephone caller, SMS alarm module, telephone dialer alarm, wireless alarm, GPRS module, 4G and 5G alarm module) is used to alert relevant personnel via dialing or SMS. This serves as a safety monitoring system for human entry into specific areas of bathrooms or toilets; and photoelectric reflective detectors are also used. Various detectors, photoelectric switches, proximity switches, radar human body detection modules, microwave detection modules, ultrasonic detectors, and mechanical contact switches (such as door closing switches with closed contacts and door opening switches with open contacts) are used as detection heads. Then, any timer is controlled to accumulate the time it takes for a person to enter or leave a relevant area, causing the timer to restart the accumulation when a person approaches. This achieves the technical solution of monitoring for potential accidents such as falls or sudden illnesses and coma in the sleep, especially for the elderly, at any location within or outside the home. (This includes setting up detection mechanisms to detect burglars entering the house through doors or windows, detecting electrical leaks and fires, and combining this embodiment to detect the safety of people in the home, as well as reducing functions based on this application). The actual functions achieved are consistent with this application, and therefore all fall within the scope of protection of the claims of this invention. The actual product developed using this application has verified its reliable safety monitoring effect and is currently in the mass production implementation stage. Its market launch will bring significant social benefits and has good application prospects.

[0032] The foregoing has shown and described the basic principles and main features of the present invention, as well as its advantages. It will be apparent to those skilled in the art that the present invention is limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or basic characteristics. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in the embodiments can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
