Fig. 1 is a schematic structural diagram of a monitoring device according to an embodiment of the present invention, and according to an aspect of the present invention, the monitoring device includes:
a controller 10, and a positioning module 20, a sensing module 30 and a communication module 40 each 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;
illustratively, as shown in fig. 1, a core component of the monitoring device is a controller 10, the controller 10 may be a Micro Controller Unit (MCU), which is also called a single-chip microcomputer or a single-chip microcomputer, and circuits with various functions may be integrated on a single chip to form a chip-level computer, so as to perform different combination control for different applications.
The controller 10 is coupled to a plurality of modules including a positioning module 20, a sensing module 30, and a communication module 40. The positioning module 20 is used for positioning, specifically, there are various ways to trigger the positioning module 20 to position the current position, and the positioning module 20 may be used to position the device immediately after the monitoring apparatus is started, or may be used to position the device when the device is restarted, or may be used to manually reposition when the acceleration sensor 32 of the monitoring device detects that the device is started later, and the positioning module 20 may be triggered to work under various conditions, so as to ensure that the monitoring apparatus can obtain the most accurate geographic position at present.
Specifically, in order to increase the positioning accuracy and ensure that the current geographic position can be positioned in various applications, the monitoring device is provided with a plurality of positioning modules, and when the positioning module 20 performs positioning, at least one positioning signal of the monitoring device needs to be acquired and transmitted to the controller 10, so as to wait for the processing of the controller 10, and store the current position information or send the current position information to the corresponding device. The setting of multiple location module not only can improve the accuracy of location, still is applicable to various scenes, even also can use in remote position and fix a position through orientation module 20.
The sensing module 30 continuously senses a first moving state associated with a target object within a preset area and a second moving state associated with the monitoring apparatus after the monitoring apparatus is started, and transmits the sensed first moving state and second moving state to the controller 10;
the sensing module 30 is provided with various sensors for collecting information data, the sensors are a detecting device capable of sensing the measured information and converting the sensed information into electrical signals or other information in a required form according to a certain rule for outputting, so as to meet the requirements of information transmission, processing, storage, display, recording, control, etc., and in many apparatuses, the sensors are the prerequisite for realizing automatic detection and automatic control.
When the monitoring device is detected to be activated, some sensors in the sensing module 30 are activated correspondingly and continue to sense. In this embodiment, the sensing module 30 continuously detects a specific target in a preset area, wherein the monitoring device can be placed near the doorway or in a position with a relatively large number of radiation areas. The preset area may be a specific room, or corridor, and generally includes a location where the target object appears most frequently. Specifically, at least two important pieces of information need to be acquired.
One of the information is a first moving state corresponding to the target object in the preset area, and the moving state of the target object reflected by the first moving state, for example, when the target object is an old person, the moving track of the old person, the number of times the old person appears in a specific place, the time length of the old person at some positions such as a sofa table, and which room the old person is currently in can be determined according to the first moving state.
The other information is a second moving state corresponding to the monitoring device, and besides the motion state of the target object is acquired, the stable existence of the monitoring device also needs to be ensured. When the position of the monitoring device is abnormal, in order to ensure that the state of the target object can be known in time, the abnormal condition of the monitoring device needs to be determined in time. For example, when the monitoring device is automatically or manually separated from the installation position, or manually damaged, the abnormal condition of the monitoring device can be known in time through the second moving state obtained by the sensing module 30, so that the stability of the monitoring device is ensured.
After the sensing module 30 collects the information related to the first moving state and the second moving state, the information is transmitted to the controller 10, so that the controller 10 can analyze and process the data.
The controller 10 determines position information of the monitoring apparatus 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 alarm information to the communication module 40 if it is determined that an abnormality occurs, wherein the alarm information includes the position information;
for example, after obtaining at least one positioning signal sent by the positioning module 20, the controller 10 processes the positioning signal to determine the position information of the monitoring device, stores the position information in a local memory, and may also transmit the current geographic position to a background management device such as a cloud platform, a management platform, a target terminal device, and the like through a communication system.
After receiving the first moving state and the second moving state output by the sensing module 30, the controller 10 determines the motion condition of the target object according to the first moving state, and determines whether there is an abnormal state, such as that the target object is not detected continuously or the target object is not moved continuously at an unreasonable position. Similarly, the controller 10 analyzes whether the monitoring device is displaced or detached, or the like, according to the second movement state.
If any abnormal state is detected by the controller 10, alarm information is sent to the communication module 40 if it is determined that an abnormality has occurred. When an abnormal state occurs, in order to ensure that the background management device determines the place where the abnormality occurs in time, the controller 10 loads the current position information in the alarm information, and needs to accurately report the specific abnormal situation in addition to the position information, so that the background manager can analyze the specific abnormal situation in time after receiving the information.
And the communication module 40 sends the alarm information to a background management device on a preset communication link.
For example, the communication module 40 may communicate with the outside to send various information to the background management device, and may also receive various information sent by the background management device. When an abnormal condition occurs, the communication module 40 sends the alarm information to the background management device on a preset communication link.
Further, 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.
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. Under the condition that the monitoring equipment has network signals, the GPS positioning module 21 can be started to carry out positioning; a SIM (Subscriber Identity Module) card may be installed in the monitoring device, where the SIM card is an IC card held by a mobile Subscriber of the GSM system, and is also called a Subscriber Identity Module (SIM), and when the SIM card has a signal, the location of the monitoring device may be located by the wireless base station locating Module 22. When the monitoring equipment is connected with the WIFI hotspot, the WIFI positioning module 23 can be started to position.
When the monitoring device triggers the positioning function, the signal strengths of the current three positioning modules are 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 this application, even in remote area, monitoring device also can acquire the signal of a location module at least, when not having the WIFI focus, can fix a position through GPS location module 21 and wireless base station location module 22, even do not have the flow signal, can also fix a position according to mobile network, uses wireless base station location module 22 to confirm current geographical position. When detecting special personage's safety problem through monitored control system, in case abnormal situation appears, it is very important to confirm the place that appears unusually in the shortest time, and positional information is confirmed through multiple location module to this application, and the position when the guarantee can both in time send abnormal state under various circumstances provides the guarantee for guaranteeing special personage's safety.
Further, 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 position information according to the positioning signal corresponding to the target positioning module.
For example, after receiving the second positioning signal and the third positioning signal of the first positioning signal corresponding to the three positioning modules, the controller 10 performs a comparative analysis on the signal strengths of the three positioning signals, determines the positioning module with the highest signal strength as the target positioning module, and then obtains the positioning signal corresponding to the target positioning module, and analyzes the positioning signal to obtain the position information of the monitoring device. In practical application, the position information can be determined according to the three positioning signals at the same time, and then the obtained position information is compared to obtain the most accurate position. The positioning can be carried out again after the preset time, and the results of multiple positioning are compared to obtain the accurate position. For the mode of acquiring the position, a plurality of positioning modes can be combined according to 3 positioning modules, and the positioning mode is not limited in the invention.
Further, the sensing module 30 includes an infrared sensor 31, and the infrared sensor 31 continuously detects infrared waves in the preset region after the monitoring device is started, determines the first moving state associated with the target object according to the detection result, and transmits the first moving state to the controller 10.
Illustratively, the sensing module 30 includes an infrared sensor 31, and the infrared sensor 31 is a sensor for performing data processing by using infrared rays, and has the advantage of high sensitivity. Infrared is the abbreviation of infrared, and as long as the temperature of all objects in nature is higher than the absolute temperature (-273 ℃), molecules and atoms move irregularly, and the surface of the object radiates infrared continuously. Infrared is an electromagnetic wave having a wavelength in the range of 760nm to 1mm, and is not visible to the human eye. The infrared sensor 31 is a sensing device that detects infrared rays radiated from the surface of an object and not seen by the human eye.
The infrared sensor 31 needs to continuously detect infrared waves in the preset area after the monitoring device is started, detect the current position of the target object, and then transmit the first moving state to the controller 10. The controller 10 analyzes the activity state of the target object based on the stored position data. And specifically, determining the moving state of the target object according to the analysis result.
Further, in a case where infrared waves radiated by the target object in the preset region are not detected for a first preset time period, and/or in a case where a displacement amount of the target object in the preset region is detected to be lower than a preset first displacement threshold value in a second preset time period, the infrared sensor 31 determines that the first movement state associated with the target object is "abnormal".
Illustratively, the controller 10 analyzes the data collected by the infrared sensor 31 to determine whether the data is in an abnormal state, and specifically, at least two abnormal situations can be detected.
The first is that the target object does not continuously appear in the preset area, and may be that the target object has an abnormal condition at a position where the monitoring device does not detect the target object, and the controller 10 determines that the first moving state associated with the target object is "abnormal" in a case that the infrared wave radiated by the target object in the preset area is not detected continuously for a first preset time period.
Alternatively, in the case where an abnormality occurs in the target object in the detection area, for example, the target object falls into the living room and cannot act, or the target object acts abnormally, and the movement position is small, that is, in the case where the amount of displacement of the target object in the preset area is detected to be lower than the preset first displacement threshold value within the second preset time period, the infrared sensor 31 determines that the first movement state associated with the target object is "abnormal".
Further, the sensing module 30 further includes an acceleration sensor 32, the acceleration sensor 32 continuously senses the displacement of the monitoring device, and determines that the second movement state associated with the monitoring device is "abnormal" if the sensed displacement is greater than a preset second displacement threshold.
For example, in order to detect the displacement of the monitoring device, the sensing module 30 further includes an acceleration sensor 32, the acceleration sensor 32 continuously senses the displacement of the monitoring device during the use of the monitoring device, and the moving speed and the moving distance measured by the acceleration sensor 32 are zero in the static state. Wherein, in case 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, it is determined that the second moving state associated with the monitoring device is an "abnormal" state. For example, if the acceleration sensor 32 is tilted and opened or removed without authorization, it is judged that the monitoring device is abnormal.
Further, the controller 10 determines that an abnormality occurs and transmits the alarm information to the communication module 40 in a case where the first movement state is "abnormal" or the second movement state is "abnormal".
For example, in order to enable the monitor to acquire the abnormal state as early as possible, the controller 10, when determining any abnormal state, sends the specific condition of the abnormality to the communication module 40, and further sends an alarm message to the background monitoring device through the communication module 40. Specifically, the "abnormality" is that the first movement state is "abnormality" or that the second movement state is "abnormality".
Further, the monitoring device further includes a manual alarm mechanism 50 electrically connected to the controller 10, the manual alarm mechanism 50 sends a manual alarm indication to the controller 10 after receiving a 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 position information.
Illustratively, the monitoring device is capable of automatically alarming upon detection of an abnormal condition, and also has a manual alarm module, which incorporates a manual alarm mechanism 50. The manual alert mechanism 50 may be triggered when the target object seeks help by itself noticing a physical abnormality or an unmanageable condition. Wherein the manual alarm mechanism 50 may be designed as a special SOS button or alarm pull cord or ring for easy pulling.
Further, the monitoring device further includes a voice alarm module 60 electrically connected to the controller 10, the voice alarm module 60 sends a voice alarm instruction to the controller 10 after recognizing a preset keyword in the voice sent by the target object, and the controller 10 sends voice alarm information to the communication module 40 after receiving the voice alarm instruction, wherein the voice alarm information also includes the location information.

The voice alarm module 60 may recognize preset keywords, such as "save life" and "please alarm", and may preset dialect keywords in addition to preset keywords of mandarin. When the voice alarm module 60 recognizes a preset keyword in the voice uttered by the target object, it sends a voice alarm instruction to the controller 10 according to the content of the keyword uttered by the target object. The controller 10 sends voice alarm information to the communication module 40 after receiving the voice alarm indication. Wherein, in order to obtain the geographical position of the help seeker in time, the voice alarm information also comprises the position information.

The monitoring device is further provided with a voice call module 70, and the voice call module 70 can be used for making and receiving calls. When the controller 10 sends any alarm information, the call for help is made through the voice call module 70. The alarm information may be various, and may be automatic alarm information, or may be manual alarm information sent by the target object through the manual alarm mechanism 50, or may be a preset target telephone number that is triggered by the voice call module 70 during the voice alarm information, where the target telephone number may be a telephone number of a background administrator, or a telephone number of an emergency contact, or may be a telephone number of 120, an emergency call.
