[0015] The following will combine the accompanying drawings to elaborate in detail on the specific embodiments of an abnormal alarm device provided in the embodiments of the present utility model. It should be noted that the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.
[0016] The embodiments of the present utility model provide an abnormal alarm device, as Figure 1 shown, which may include: an inertial sensor, at least one first comparator, and an alarm;
[0017] The inertial sensor is connected to the first input terminal a of the first comparator. The inertial sensor is disposed above the entry door and is configured to: detect the movement parameters of the entry door and transmit them to the first input terminal a of the first comparator; wherein, the movement parameters include at least one of: movement speed, movement acceleration, and angular velocity; the types of movement parameters detected by the inertial sensor are correspondingly set with at least one first comparator; that is to say, the inertial sensor is used to detect the movement of the entry door, so the inertial sensor is disposed above the entry door, and the inertial sensor can move according to the movement of the entry door, and the position of the inertial sensor is not fixed;
[0018] The second input terminal b of the first comparator is connected to the first reference terminal Vc1 for providing a first preset range. The output terminal of the first comparator is connected to the alarm. The first comparator is configured to: in response to the movement parameters of the corresponding entry door exceeding the first preset range, output a first signal to the alarm;
[0019] The alarm is configured to: in response to receiving the first signal, issue an abnormal warning.
[0020] Thus, by setting an inertial sensor on the entrance door, the inertial sensor can detect the movement parameters of the entrance door to reflect the state of the entrance door. The first comparator can output relevant signals to the alarm by comparing the size relationship between the movement parameters and the first preset range, so that the alarm can issue an abnormal warning, thereby timely reminding the owner or the surrounding neighbors and protecting the personal and property safety of the owner.
[0021] Among them, the first signal can be a high-level signal or a low-level signal, which can be specifically set according to actual needs and is not limited here. Taking the first signal as a high-level signal as an example, when the first comparator determines that the movement parameter exceeds the first preset range, it outputs a high-level signal to the alarm; when it determines that the movement parameter does not exceed the first preset range, it outputs a low-level signal to the alarm. The alarm issues an abnormal warning when receiving the high-level signal and may not issue an abnormal warning when receiving the low-level signal.
[0022] Exemplarily, the inertial sensor can be used to detect parameters such as speed, acceleration, and angular velocity. Therefore, the movement parameters detected by the inertial sensor can include at least one of the movement speed, movement acceleration, and angular velocity. Correspondingly, the inertial sensor includes at least one of a speed sensor, an acceleration sensor, and an angular velocity sensor. And, the number of types of sensors included in the inertial sensor is the same as the number of settings of the first comparator, and each sensor in the inertial sensor is correspondingly connected to a first comparator. In this way, the movement parameters detected by each type of inertial sensor can be output to the corresponding first comparator, so that the first comparator can determine whether the corresponding movement parameter exceeds the first preset range, thereby outputting the first signal to the alarm to achieve warning.
[0023] For example, when the inertial sensor only detects one movement parameter, such as but not limited to movement acceleration, the inertial sensor can be an acceleration sensor, and one first comparator can be set, not shown in the figure. Or, when the inertial sensor can detect multiple movement parameters, such as but not limited to movement acceleration and angular velocity, the inertial sensor can include an acceleration sensor and an angular velocity sensor. At this time, two first comparators can be set, and one of the first comparators is connected to the acceleration sensor, and the other first comparator is connected to the angular velocity sensor, not shown in the figure. Or, as Figure 2 shown, when the inertial sensor can detect the movement speed, movement acceleration, and angular velocity, the inertial sensor includes a speed sensor, an acceleration sensor, and an angular velocity sensor. Correspondingly, three first comparators are set, and these three first comparators are respectively connected to the speed sensor, the acceleration sensor, and the angular velocity sensor. That is to say, the number of settings of the first comparator can be determined according to the types of movement parameters that the inertial sensor can detect.
[0024] Further, when multiple first comparators are provided, the first reference terminals corresponding to different first comparators are different, and the first preset ranges provided by different first reference terminals are different. For example, in Figure 2 the first reference terminal connected to the topmost first comparator in the figure is denoted as Vc1, the first reference terminal connected to the middle first comparator in the figure is denoted as Vc2, and the first reference terminal connected to the bottommost first comparator in the figure is denoted as Vc3. The first preset ranges provided by Vc1, Vc2, and Vc3 are all different, so that each movement parameter has a corresponding first preset range, thereby increasing the accuracy of the judgment result.
[0025] Of course, the types of movement parameters detected by the inertial sensor are not limited to including movement speed, movement acceleration, and angular velocity, but may also include other parameters well-known to those skilled in the art that can reflect the movement of the entrance door, such as the tilt angle of the entrance door, etc., which can be specifically set according to actual needs and are not limited herein.
[0026] Exemplarily, as Figure 3 shown, the abnormal alarm device may further include: a sound sensor and a second comparator. The sound sensor is disposed above the entrance door. The sound sensor is connected to the first input terminal a of the second comparator. The sound sensor is configured to: detect the volume at the entrance door and transmit the detected volume to the first input terminal a of the second comparator;
[0027] The second input terminal b of the second comparator is connected to a second reference terminal Vc2 for providing a second preset range. The output terminal of the second comparator is connected to the alarm. The second comparator is configured to: in response to the volume at the entrance door exceeding the second preset range, output a second signal to the alarm;
[0028] The alarm is further configured to: in response to receiving the second signal, issue an abnormal warning.
[0029] In this way, the abnormal alarm device can not only detect the movement parameters of the entrance door, but also detect the volume at the entrance door, so as to detect whether an intrusion has occurred indoors from multiple angles, thereby increasing the accuracy of the judgment result.
[0030] Wherein, the second signal may be a high-level signal or a low-level signal, which can be specifically set according to actual needs and is not limited herein. Taking the second signal as a high-level signal as an example, when the second comparator determines that the volume exceeds the second preset range, it outputs a high-level signal to the alarm; when it determines that the volume does not exceed the second preset range, it outputs a low-level signal to the alarm. The alarm issues an abnormal warning when receiving the high-level signal and may not issue an abnormal warning when receiving the low-level signal.
[0031] And, since the alarm is respectively connected to the first comparator and the second comparator, it can be set to:
[0032] When the alarm receives at least one of the first signal and the second signal, an abnormal warning occurs.
[0033] Alternatively, when the alarm receives both the first signal and the second signal, an abnormal warning occurs. At this time, it is possible to avoid misjudgment caused by the master's unconventional operation resulting in the movement parameter exceeding the first preset range, and it is also possible to avoid misjudgment caused by the volume exceeding the second preset range due to multiple people talking around. Thus, an abnormal warning will only occur when the movement parameter exceeds the first preset range and the volume exceeds the second preset range, improving the accuracy of the judgment result and reducing the probability of misjudgment. Based on this, the following settings can be made:
[0034] Such as Figure 4 As shown, the abnormal alarm device may further include a logical AND. The first input terminal of the logical AND is connected to the output terminal of the first comparator, the second input terminal of the logical AND is connected to the output terminal of the second comparator, and the output terminal of the logical AND is connected to the alarm. The logical AND is configured to: in response to receiving the first signal and the second signal, output an alarm signal to the alarm. The alarm is specifically configured to: in response to receiving the alarm signal, issue an abnormal warning. In this way, through the processing of the logical AND, the alarm can be made to issue an abnormal warning only when the first signal and the second signal are received, thereby improving the accuracy of the judgment result and reducing the probability of misjudgment.
[0035] Exemplarily, as Figure 5 As shown, the abnormal alarm device may further include: a vibration sensor and a third comparator. The vibration sensor is disposed above the entrance door. The vibration sensor is configured to: detect the vibration frequency of the entrance door and output the detected vibration frequency to the first input terminal a of the third comparator;
[0036] The second input terminal b of the third comparator is connected to a third reference terminal Vc3 for providing a third preset range. The output terminal of the third comparator is connected to the alarm. The third comparator is configured to: in response to the detected vibration frequency exceeding the third preset range, output a third signal to the alarm;
[0037] The alarm is further configured to: in response to receiving the third signal, issue a vibration abnormal warning.
[0038] In this way, the vibration sensor can detect the vibration frequency of the entrance door caused by knocking. When the vibration frequency exceeds the third preset range, it indicates that someone is knocking abnormally. At this time, the alarm can issue a movement abnormal warning to alert people around.
[0039] Moreover, the vibration sensor can work before the inertial sensor and the sound sensor. For example, the vibration sensor first detects the vibration frequency of the entrance door and determines whether there is a stranger knocking abnormally based on this. In this case, if the host is at home, it can remind the host that there may be danger outside the entrance door, enabling the host to take safety measures in a timely manner. Then the inertial sensor detects the movement parameters of the entrance door, and the sound sensor detects the volume, so as to further determine whether an indoor intrusion has occurred. Of course, the vibration sensor, the inertial sensor, and the sound sensor can work simultaneously, which can be specifically set according to actual needs and is not limited here.
[0040] Among them, the third signal can be a high-level signal or a low-level signal, which can be specifically set according to actual needs and is not limited here. Taking the third signal as a high-level signal as an example, when the third comparator determines that the vibration frequency exceeds the third preset range, it outputs a high-level signal to the alarm; when it determines that the vibration frequency does not exceed the third preset range, it outputs a low-level signal to the alarm. The alarm issues a warning of abnormal vibration of the entrance door when receiving the high-level signal, and may not issue a warning of abnormal vibration of the entrance door when receiving the low-level signal.
[0041] Exemplarily, the settings of the first preset range, the second preset range, and the third preset range can be set according to the host's living habits to avoid warnings caused by the host knocking on the door, opening the door, or speaking, thereby improving the accuracy of the judgment result and reducing misjudgment.
[0042] Exemplarily, as Figure 5 shown, the abnormal alarm device may further include a wireless transceiver, which is respectively connected to the terminal device and the first comparator;
[0043] The first comparator is further configured to: in response to the movement parameters of the corresponding entrance door exceeding the first preset range, output a first signal to the wireless transceiver;
[0044] The wireless transceiver is configured to: in response to receiving the first signal, send a prompt signal to the terminal device.
[0045] Among them, when the terminal device is a smart terminal such as a mobile phone, a computer, a tablet, or a TV used by the host, a prompt can be sent to the terminal device through the wireless transceiver to remind the host that there may be danger currently; when the terminal device is a server of the monitoring center, a prompt can be sent to the server through the wireless transceiver so that the staff of the monitoring center can take safety measures in a timely manner.
[0046] Moreover, when there are multiple first comparators, the wireless transceiver can be connected to at least some of the first comparators, which can be specifically set according to actual needs to meet the requirements of different application scenarios.
[0047] Furthermore, the wireless transceiver is also connected to the alarm. In this case, the wireless transceiver is further configured to: receive the alarm cancellation signal sent by the terminal device and transmit the alarm cancellation signal to the alarm; the alarm is further configured to: in response to receiving the alarm cancellation signal, cancel the alarm. In this way, when the danger or false alarm is lifted in a timely manner, the terminal device and the wireless transceiver can control the alarm to stop alarming, so as to avoid causing adverse effects on the surrounding environment.
[0048] Of course, when the wireless transceiver is connected to the alarm, it can also be set that: when the alarm receives the first signal, it outputs a warning signal to the wireless transceiver, so that when the wireless transceiver receives the warning signal, it sends a prompt signal to the terminal device, which can improve the accuracy of the prompt and avoid false prompts.
[0049] Exemplarily, as Figure 5 shown, the abnormal alarm device may further include a door magnetic sensor, and the door magnetic sensor is connected to the inertial sensor. To avoid the drawing from being too complex, Figure 5 the connection relationship between the door magnetic sensor and the inertial sensor is not shown in the figure. The door magnetic sensor is configured to: in response to the entry door being opened, send a detection trigger signal to the inertial sensor; specifically, the inertial sensor is configured to: in response to receiving the detection trigger signal, detect the movement parameters of the entry door. And, the door magnetic sensor is further configured to: in response to the entry door not being opened, not send a detection trigger signal to the inertial sensor, so that when the inertial sensor does not receive the detection trigger signal, it does not start the detection function, which can reduce the power consumption of the abnormal alarm device. Of course, when the door magnetic sensor detects that the entry door is not opened, it can also send a standby signal to the inertial sensor, so that the inertial sensor is in a standby state and does not start detection, which can also reduce the power consumption of the abnormal alarm device.
[0050] And, the door magnetic sensor can also be connected to other sensors. For example, the door magnetic sensor is connected to at least one of a sound sensor and a vibration sensor. To avoid the drawing from being too complex, Figure 5 the connection relationship between the door magnetic sensor and the sound sensor and the vibration sensor is not shown in the figure. When the door magnetic sensor is connected to the sound sensor, the door magnetic sensor can also, in response to the entry door being opened, send a detection trigger signal to the sound sensor to enable the sound sensor to start detection; when the door magnetic sensor responds to the entry door not being opened, it does not send a detection trigger signal to the sound sensor or sends a standby signal to the sound sensor, so that the sound sensor does not start detection. When the door magnetic sensor is connected to the vibration sensor, the door magnetic sensor can also, in response to the entry door being opened, send a detection trigger signal to the vibration sensor to enable the vibration sensor to start detection; when the door magnetic sensor responds to the entry door not being opened, it does not send a detection trigger signal to the vibration sensor or sends a standby signal to the vibration sensor, so that the vibration sensor does not start detection. Thereby, the power consumption of the abnormal alarm device can be further reduced.
[0051] Among them, asFigure 5 As shown, the door magnetic sensor can include two parts. One part (i.e., the first part) can be installed above the door frame, and the other part (i.e., the second part) can be installed above the entry door. When the two parts are magnetically attracted, the entry door remains closed. When the two parts are separated, the entry door is opened. At this time, the second part detects the separation from the first part, so it can send a detection trigger signal to the inertial sensor to enable the inertial sensor to start the detection function. In specific implementation, the implementation manners of the first part and the second part can be set according to the actual situation, and the specific structures of the first part and the second part are not limited herein.
[0052] Exemplarily, as Figure 5 shown, the abnormal alarm device can further include: a power supply and a control switch. The control switch is respectively connected to the power supply, the inertial sensor, the first comparator, and the alarm;
[0053] The control switch is used for: in response to starting the alarm monitoring, respectively connecting the power supply to the inertial sensor, connecting the power supply to the first comparator, and connecting the power supply to the alarm; in response to closing the alarm monitoring, respectively cutting off the connection between the power supply and the inertial sensor, cutting off the connection between the power supply and the first comparator, and cutting off the connection between the power supply and the alarm.
[0054] It should be noted that, in order to avoid the drawings being too complex, in Figure 5 , only the power supply and the control switch are shown, but the connection relationships between the power supply and the control switch and other structures are not shown.
[0055] In this way, when starting the alarm monitoring, the power supply can supply power to various sensors, various comparators, the alarm, and the wireless transceiver to ensure that these devices can work normally, so as to ensure the normal operation of the abnormal alarm device. When it is not necessary to perform monitoring for a certain period of time due to certain special reasons, the connection relationship between the power supply and each device can be disconnected through the control switch, thereby closing the alarm monitoring to meet the needs of different application scenarios and improving the flexibility of the design.
[0056] Exemplarily, the alarm can include: a sound alarm, a light alarm, a voice alarm, etc. The alarm method can be set according to the actual needs to meet the needs of different application scenarios and improve the flexibility of the design.
[0057] Moreover, when the alarm determines when to issue a warning, it can be set to: issue a warning when receiving the corresponding signal sent by any one of the sensors; or, issue a warning when receiving the corresponding signals sent by multiple sensors; specifically, it can be set according to the actual needs, and it is not limited herein.
[0058] Exemplarily, in the embodiment of the present utility model, the door magnet can be built into the door frame, and other structures in the abnormal alarm device can be built into the entrance door, so as to realize the integration of the abnormal alarm device with the entrance door and the door frame.
[0059] Alternatively, the abnormal alarm device can include two housings. One housing is used to place the first part of the door magnet to form an independent device a, and other structures in the abnormal alarm device can be placed in the other housing to form another independent device b. The device a, device b, the entrance door, and the door frame are all independently arranged. When in use, the device a can be externally mounted on the door frame by means of hanging, pasting, etc., and the device b can be externally mounted on the entrance door by means of hanging, pasting, etc., so as to facilitate the installation, disassembly, and maintenance of the abnormal alarm device and improve the flexibility of use of the abnormal alarm device.
[0060] Certainly, when the abnormal alarm device does not include a door magnet, each structure in the abnormal alarm device can be integrated in a box body to form an independent device, so that the device can also be externally mounted on the entrance door by means of hanging, pasting, etc., so as to facilitate the installation, disassembly, and maintenance of the abnormal alarm device and improve the flexibility of use of the abnormal alarm device.
[0061] Moreover, when the abnormal alarm device includes a door magnet, the door magnet can be used to trigger various sensors to start the detection function. When no door magnet is provided, the control switch can be used to trigger various sensors to start the detection function. The specific implementation process can include:
[0062] The control switch can be implemented in the form of a mechanical switch, and the control switch can be arranged on the surface of the box body, so as to close the control switch when abnormal alarm monitoring is required, so as to connect the power supply with the inertial sensor, connect the power supply with the first comparator, and connect the power supply with the alarm. At this time, the inertial sensor starts to detect under the drive of the electric energy provided by the power supply, so as to start the alarm monitoring. When abnormal alarm monitoring is not required, the control switch is disconnected to cut off the power supply from the inertial sensor, cut off the power supply from the first comparator, and cut off the power supply from the alarm. At this time, the inertial sensor closes the detection, so as to turn off the alarm monitoring.
[0063] Alternatively, the control switch can also be connected to a wireless transceiver, and the closing and opening of the control switch can be controlled through a terminal device, so as to control the start and stop of the detection function of the inertial sensor, so as to realize wireless control.
[0064] It should be understood that for other sensors, such as a sound sensor and a vibration sensor, the triggering control method can be similar to that of the inertial sensor. The control switch can control whether the power supply is connected to these sensors, so as to control when these sensors start to detect and when to close the detection.
[0065] It should be noted that in the embodiments of the present utility model, the abnormal alarm device can be applied not only to the entry door, but also to structures such as windows, drawers, counters, etc. that need to be monitored. When applied to a window, the device installed on the entry door can be installed on an openable window. Or when applied to a drawer, the device installed on the entry door can be installed on the drawer. Or when applied to a counter, the device installed on the entry door can be installed on an openable cabinet door. Specifically, corresponding modifications can be made according to the actual situation, but the principle of alarm is basically similar and will not be elaborated here.
[0066] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these changes and modifications.
