[0025] Figure 1 A schematic diagram of the structure of a monitoring device provided by an embodiment of the present invention. According to one aspect of the present invention, the present invention provides a monitoring device, the monitoring device comprising:

[0026] A controller 10 and a positioning module 20, a sensor module 30 and a communication module 40, each of which is electrically connected to the controller 10; the positioning module 20 acquires at least one positioning signal of the monitoring device after the monitoring device is started, and transmits the at least one positioning signal to the controller 10;

[0027] For example, Figure 1 As shown, the core component of the monitoring device is the controller 10, which can be a microcontroller unit (MCU). MCU is also called a single-chip microcomputer or a single-chip microcomputer. It can integrate circuits with various functions on a single chip to form a chip-level computer to perform different combination controls for different application scenarios.

[0028] The controller 10 is connected to a plurality of modules, including a positioning module 20, a sensor module 30 and a communication module 40. The positioning module 20 is used for positioning. Specifically, there are multiple ways to trigger the positioning module 20 to locate the current position. The device can be located immediately after the monitoring device is started, or when the device is restarted, or the positioning function is started after the acceleration sensor 32 of the monitoring device detects that the device is being moved, or it can be relocated manually. Multiple situations can trigger the positioning module 20 to work to ensure that the monitoring device can obtain the most accurate current geographical location.

[0029] Specifically, in order to increase the accuracy of positioning and ensure that the current geographical location can be positioned in various application scenarios, a variety of positioning modules are set in the monitoring device. When the positioning module 20 performs positioning, it is necessary to obtain at least one positioning signal of the monitoring device and transmit at least one positioning signal to the controller 10 for processing by the controller 10, storing the current location information or sending it to the corresponding device. The setting of multiple positioning modules can not only improve the accuracy of positioning, but also be applicable to various scenarios. Even in remote locations, positioning can be performed through the positioning module 20.

[0030] The sensing module 30 continuously senses a first movement state associated with a target object in a preset area and a second movement state associated with the monitoring device after the monitoring device is started, and transmits the sensed first movement state and second movement state to the controller 10;

[0031] Exemplarily, a variety of sensors are provided on the sensing module 30 for collecting information data. The sensor is a detection device that can sense the information being measured and can convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control. In many devices, sensors are the prerequisite for realizing automatic detection and automatic control.

[0032] When the monitoring device is detected to be activated, some sensors in the sensor module 30 are activated accordingly and continue to sense. In this solution, the sensor module 30 continuously detects specific targets in the preset area, wherein the monitoring device can be placed near the door or in a location with a large radiation area. The preset area can be a specific room or corridor, generally including the location where the target object appears most frequently. Specifically, at least two important information needs to be obtained.

[0033] One of the information is the first movement state corresponding to the target object in the preset area. The first movement state reflects the motion state of the target object. For example, when the target object is an elderly person, the activity trajectory of the elderly person, the number of times the elderly person appears in a specific location, the length of time the elderly person stays in certain positions such as the sofa or table, and which room the elderly person is currently in, etc. can be determined based on the first movement state.

[0034] Another piece of information is the second movement state corresponding to the monitoring device. In addition to obtaining the movement state of the target object, it is also necessary to ensure the stable existence of the monitoring device. When the position of the monitoring device is abnormal, in order to ensure that the state of the target object can be understood in time, it is necessary to promptly determine the abnormal situation of the monitoring device. For example, when the monitoring device automatically or manually leaves the installation position, or is artificially damaged, the second movement state obtained by the sensor module 30 can promptly understand the abnormal situation of the monitoring device, thereby ensuring the stability of the monitoring device.

[0035] After the sensor module 30 collects information related to the first movement state and the second movement state, it transmits the information to the controller 10, so that the controller 10 analyzes and processes the data.

[0036] The controller 10 determines the location information of the monitoring device based on the at least one positioning signal, determines whether an abnormality occurs according to the first movement state and the second movement state, and sends an alarm message to the communication module 40 when it is determined that an abnormality occurs, wherein the alarm message includes the location information;

[0037] Exemplarily, after obtaining at least one positioning signal sent by the positioning module 20, the controller 10 processes the positioning signal to determine the location information of the monitoring device, and stores the location information in the local memory. It can also transmit the current geographic location to the cloud platform, management platform, target terminal equipment and other background management devices through the communication system.

[0038] After receiving the first movement state and the second movement state output by the sensor module 30, the controller 10 determines the movement of the target object according to the first movement state, and judges whether there is an abnormal state, such as the target object is continuously not detected, or the target object is continuously not moving at an unreasonable position. Similarly, the controller 10 analyzes whether the monitoring device is displaced or disassembled according to the second movement state.

[0039] If the controller 10 detects any abnormal state, it will send an alarm message to the communication module 40 when it is determined that an abnormality has occurred. When an abnormal state occurs, in order to ensure that the background management device can promptly determine the location where the abnormality has occurred, the controller 10 loads the current location information in the alarm message. In addition to the location information, the specific abnormal situation needs to be accurately reported so that the background manager can promptly analyze the specific situation of the abnormality after receiving the information.

[0040] The communication module 40 sends the alarm information to the background management device on a preset communication link.

[0041] Exemplarily, the communication module 40 can communicate with the outside world, send various information to the background management device, and also receive various information sent by the background management device. When an abnormal situation occurs, the communication module 40 sends the alarm information to the background management device on a preset communication link.

[0042] Furthermore, the positioning module 20 includes a GPS positioning module 21, a wireless base station positioning module 22 and a WIFI positioning module 23, wherein, after the monitoring device is started, the GPS positioning module 21 transmits a first positioning signal with a first signal strength to the controller 10, the mobile base station positioning module transmits a second positioning signal with a second signal strength to the controller 10, and the WIFI positioning module 23 transmits a third positioning signal with a third signal strength to the controller 10.

[0043] Exemplarily, the positioning module 20 includes three modules, specifically a GPS positioning module 21, a wireless base station positioning module 22, and a WIFI positioning module 23. When the monitoring device has a network signal, the GPS positioning module 21 can be enabled for positioning; a SIM (Subscriber Identity Module) card can also be installed in the monitoring device. The SIM card is an IC card held by a mobile user of the GSM system, also known as a user identification card. When the SIM card has a signal, the position of the monitoring device can be located through the wireless base station positioning module 22. When the monitoring device is connected to a WIFI hotspot, the WIFI positioning module 23 can also be enabled for positioning.

[0044] When the monitoring device triggers the positioning function, the signal strength of the three current positioning modules is detected. Specifically, the GPS positioning module 21 transmits a first positioning signal with a first signal strength to the controller 10, the mobile base station positioning module transmits a second positioning signal with a second signal strength to the controller 10, and the WIFI positioning module 23 transmits a third positioning signal with a third signal strength to the controller 10. In the present application, even in remote areas, the monitoring device can at least obtain the signal of one positioning module. When there is no WIFI hotspot, positioning can be performed through the GPS positioning module 21 and the wireless base station positioning module 22. Even if there is no traffic signal, positioning can be performed based on the mobile network, and the wireless base station positioning module 22 is used to determine the current geographical location. When the monitoring system detects the safety of special people, once an abnormal condition occurs, it is very important to determine the location of the abnormality in the shortest time. The present application determines the location information through a variety of positioning modules to ensure that the location of the abnormal state can be sent in time under various circumstances, which provides a guarantee for ensuring the safety of special people.

[0045] Furthermore, after receiving the first positioning signal, the second positioning signal and the third positioning signal, the controller 10 determines the positioning module with the highest signal strength as the target positioning module, and determines the location information according to the positioning signal corresponding to the target positioning module.

[0046] Exemplarily, after receiving the first positioning signal, the second positioning signal and the third positioning signal corresponding to the three positioning modules, the controller 10 compares and analyzes the signal strengths of the three positioning signals, determines that the positioning module with the highest signal strength is the target positioning module, and then obtains the positioning signal corresponding to the target positioning module, and analyzes it to obtain the location information of the monitoring device. In practical applications, the location information can also be determined based on the three positioning signals at the same time, and then the obtained location information can be compared to obtain the most accurate location. Positioning can also be performed again after a preset time, and the results of multiple positioning can be compared to obtain the accurate location. As for the method of obtaining the position, a variety of positioning methods can be combined according to the three positioning modules, and the present invention does not limit the positioning method.

[0047] Furthermore, the sensing module 30 includes an infrared sensor 31, which continuously detects infrared waves in the preset area after the monitoring device is started, determines the first movement state associated with the target object based on the detection result, and transmits the first movement state to the controller 10.

[0048] Exemplarily, the sensing module 30 includes an infrared sensor 31, which is a sensor that uses infrared rays to process data and has the advantage of high sensitivity. Infrared is the abbreviation of infrared rays. All objects in nature, as long as the temperature is higher than the absolute temperature (-273°C), have irregular movement of molecules and atoms, and their surfaces continuously radiate infrared rays. Infrared rays are a type of electromagnetic wave with a wavelength range of 760nm to 1mm, which is invisible to the human eye. The infrared sensor 31 is a sensing device that detects infrared rays radiated from the surface of an object that are invisible to the human eye.

[0049] After the monitoring device is started, the infrared sensor 31 needs to continuously detect the infrared waves in the preset area, detect the current position of the target object, and then transmit the first movement state to the controller 10. The controller 10 analyzes the activity state of the target object according to the stored position data. Specifically, the movement state of the target object is determined according to the analysis result.

[0050] Further, when the infrared waves radiated by the target object in the preset area are not detected continuously within the first preset time period, and / or when the displacement of the target object in the preset area is detected to be lower than a preset first displacement threshold within the second preset time period, the infrared sensor 31 determines that the first movement state associated with the target object is "abnormal".

[0051] Exemplarily, the controller 10 analyzes the data collected by the infrared sensor 31 to determine whether it is an abnormal state. Specifically, at least two abnormal situations can be detected.

[0052] The first is that the target object continues to fail to appear in the preset area. It may be that an abnormal situation occurs in the target object at a position that cannot be detected by the monitoring device. The controller 10 analyzes that the infrared waves radiated by the target object in the preset area have not been detected for a long time within the first preset time period, and determines that the first movement state associated with the target object is "abnormal".

[0053] Another situation is that the target object has an abnormality in the detection area, such as falling down in the living room and being unable to move, or moving abnormally, and moving very little. That is, when the displacement of the target object in the preset area is detected to be lower than the preset first displacement threshold within the second preset time period, the infrared sensor 31 determines that the first movement state associated with the target object is "abnormal".

[0054] Furthermore, the sensing module 30 also includes an acceleration sensor 32, which continuously senses the displacement of the monitoring device, and determines that the second movement state associated with the monitoring device is "abnormal" when the sensed displacement is greater than a preset second displacement threshold.

[0055] Exemplarily, in order to detect the displacement of the monitoring device, the sensor module 30 also includes an acceleration sensor 32. During the use of the monitoring device, the acceleration sensor 32 continuously senses the displacement of the monitoring device. In a stationary state, the moving speed and moving distance measured by the acceleration sensor 32 are both zero. Wherein, when the acceleration sensor 32 detects that the current moving speed is not zero, or the sensed displacement is greater than a preset second displacement threshold, the second moving state associated with the monitoring device is determined to be an "abnormal" state. For example, when the acceleration sensor 32 is tilted, opened or disassembled without authorization, it is determined that the monitoring device is abnormal.

[0056] Further, the controller 10 determines that an abnormality occurs and sends the alarm information to the communication module 40 when the first moving state is “abnormal” or the second moving state is “abnormal”.

[0057] Exemplarily, in order to enable the monitor to obtain the abnormal state as early as possible, the controller 10 sends the specific situation of the abnormality to the communication module 40 when determining any abnormal state, and then sends an alarm message to the background monitoring device through the communication module 40. Specifically, "abnormal" means that the first movement state is "abnormal" or the second movement state is "abnormal".

[0058] Furthermore, the monitoring device also includes a manual alarm mechanism 50 electrically connected to the controller 10, and the manual alarm mechanism 50 sends a manual alarm indication to the controller 10 after receiving the manual alarm operation performed by the target object, and the controller 10 sends manual alarm information to the communication module 40 after receiving the manual alarm indication, wherein the manual alarm information also includes the location information.

[0059] For example, the monitoring device can automatically alarm when an abnormal state is detected. The monitoring device also has a manual alarm mode, and the monitoring device integrates a manual alarm mechanism 50. When the target object himself perceives that the body is abnormal or an unmanageable situation occurs and asks for help, the manual alarm mechanism 50 can be triggered. Among them, the manual alarm mechanism 50 can be designed as a specific SOS button or an alarm pull rope or pull ring that is easy to pull.

[0060] Furthermore, the monitoring device also includes a voice alarm module 60 electrically connected to the controller 10, and the voice alarm module 60 sends a voice alarm indication to the controller 10 after recognizing preset keywords in the voice emitted by the target object, and the controller 10 sends voice alarm information to the communication module 40 after receiving the voice alarm indication, wherein the voice alarm information also includes the location information.

[0061] Exemplarily, the monitoring device can also be used for voice alarm, and the voice alarm module 60 is electrically connected to the controller 10. The voice alarm module 60 can recognize preset keywords, such as "help" and "please call the police". In addition to the preset keywords in Mandarin, dialect keywords can also be preset. When the voice alarm module 60 recognizes the preset keywords in the voice emitted by the target object, it sends a voice alarm indication to the controller 10 according to the content of the keywords emitted by the target object. After receiving the voice alarm indication, the controller 10 sends a voice alarm message to the communication module 40. In order to obtain the geographical location of the person seeking help in a timely manner, the voice alarm message also includes the location information.

[0062] Furthermore, the monitoring device also includes a voice call module 70 electrically connected to the controller 10. When the controller 10 sends the alarm information, and / or the manual alarm information, and / or the voice alarm information to the communication module 40, the voice call module 70 is triggered to automatically dial a preset target phone number.

[0063] Exemplarily, the monitoring device is also provided with a voice call module 70, which can be used to make or receive calls. However, when the controller 10 issues any alarm information, a distress call is made through the voice call module 70. There are many types of alarm information, which can be an automatic alarm alarm information, a manual alarm information issued by the target object through the manual alarm mechanism 50, or a voice alarm information that triggers the voice call module 70 to automatically dial a preset target phone. The target phone can be the phone of the backend administrator, or the phone of the emergency contact, or 120, an emergency phone.

[0064] Furthermore, the monitoring device also includes a display module 80 electrically connected to the controller 10, and the controller 10 transmits the prefabricated information to the display module 80 after receiving the prefabricated information pushed from the background management device via the communication module 40, and the display module 80 displays the prefabricated information to the target object after receiving the prefabricated information.

[0065] Exemplarily, in order to facilitate the target object to understand important information about living habits, a display module 80 is provided on the monitoring device to display prefabricated information pushed by the background management device, such as weather forecast. Data collected by the sensor, such as indoor temperature and humidity, can also be displayed. Among them, the prefabricated information is the information sent by the background management device to the communication module 40, and the communication module 40 forwards it to the display module 80. In addition, a photosensitive sensor can also be installed on the monitoring device, and the brightness of the display screen of the display module 80 can be adjusted according to the brightness information of the space collected by the photosensitive sensor to ensure that the prefabricated information can be clearly displayed at any time or light.

[0066] Furthermore, the preset communication link is a communication link based on a narrowband Internet of Things communication protocol.

[0067] For example, Narrow Band Internet of Things (NB-IoT) is an important branch of the Internet of Everything. Narrow Band Internet of Things builds a cellular network and consumes less bandwidth. It is an emerging technology in the field of Internet of Things. It supports cellular data connection of low-power devices in the wide area network and supports efficient connection of devices with long standby time and high network connection requirements. The communication link of the monitoring device of the present application is a communication link based on the narrowband Internet of Things communication protocol, which can achieve efficient and stable data transmission under long standby time.
