In the present embodiment, the location system 113 is data coupled to the monitoring devices 111. The location system 113 can include an electronic module of hardware, software, or firmware, and is configured to receive the notification signal and estimate the wearable sensor 112 relative to the notification signal using a suitable indoor positioning method.

The location system 113 is further configured to select one of the monitoring devices 111 as a target monitoring device (eg, the monitoring device 111') according to the position of the wearable sensor 112 relative to the field, and transmit the consistent energy. The signal is sent to the target monitoring device (e.g., monitoring device 111'). In the present embodiment, the target monitoring device (e.g., monitoring device 111') is the monitoring device 111 (e.g., monitoring device 111') of the monitoring device 111 that is closest to the wearable sensor 112.

In some examples utilizing the received signal strength localization method, the location system 113 can include a plurality of receivers 113a spaced apart from each other in the field and a server 113b coupled to the receivers 113a. The receiver 113a is configured to receive the notification signal from the wearable sensor 112 and generate information about the received signal strength based on the notification signal.

In this way, the use of solar power technology can effectively utilize the light energy generated by the 24-hour fluorescent lamp in the hospital, reduce the external energy consumption and continue to provide stable power for the image, and achieve continuous monitoring.

Figure 2 exemplarily illustrates a monitoring method that can be implemented by some systems. The following is a description of how the monitoring method is implemented by the monitoring system 110 described above with reference to FIGS. 1 and 2.

First, as in the procedure S201, when the wearable sensor 112 determines that the user has fallen, the notification signal is transmitted.

Then, when the notification signal is received, the location system 113 estimates the location of the wearable sensor 112 according to the notification signal, and the monitoring device according to the position of the wearable sensor 112. One of the 111 acts as a target monitoring device (e.g., monitoring device 111').

In the process S203, the location system 113 transmits a consistent energy signal to the target monitoring device (e.g., monitoring device 111').

Then, as the program S204, when the target monitoring device (for example, the monitoring device 111') receives the enabling signal from the location system 113, the image capturing module 111b of the target monitoring device (eg, the monitoring device 111') The shooting mode is operated in response to the enable signal.

In step S205, the image capturing module 111b of the target monitoring device (e.g., monitoring device 111') captures the field to generate image data.

Finally, in step S206, the processing unit 111c transmits a first alert notification to the terminal device 120 when it is determined that the field has a human body and the human body meets a first predetermined condition. In some implementations, the first alert notification is related to a location of the wearable sensor 112 relative to the field. In an operation, the display unit 121 of the terminal device 120 displays the location of the patient wearing the wearable sensor 112 relative to the hospital or the ward according to the first alert notification.

In this embodiment, before the process S206, the processing unit 111c defines a target area in the image according to the image data. In some examples, the processing unit 111c identifies the occupied area of a bed of the field in the image, and the target area is defined as excluding other areas outside the occupied area of the bed, such as other areas, for example The area occupied by the ground.

In this embodiment, the first predetermined condition includes not only the human body fall in the image, but also the human body in the image is located in the target area, and the human body is in a lying state for more than a predetermined period of time. It should be noted that the first predetermined condition includes the range of the bed that the user must not be located in the field, which can reduce the chance that the user is mistakenly judged to fall when lying down to the bed. In addition, the first predetermined condition includes that the user is lying flat for more than a predetermined period of time, so that the chance of being mistakenly judged to be a fall due to the user's embarrassment can be reduced.

It should be noted that, in an operating environment, the image capturing module 111b of all the monitoring devices 111 can be set to be in the sleep mode during the daytime, and when the program S201 to the program S204 occur, only the wearable is closest to the wearable The monitoring device 111 of the sensor 112 is switched to operate in the shooting mode, which saves power. In other embodiments, the image capturing module 111b may be configured to operate only in the shooting mode. Thus, although the programs S201 to S204 can be omitted, the power is relatively consumed.

It should be noted that merely relying on the wearable sensor 112 to determine whether the user falls or not to decide whether to issue the first warning notice may result in a false positive. For example, when the wearable sensor 112 is detached from the user, or the user is lying down on the bed, the wearable sensor 112 may determine that the user has fallen. In this regard, the present embodiment performs the second determination by the process S205 to the process S207, thereby avoiding the improper notification caused by the misjudgment of the wearable sensor 112.

In addition, when the image capturing module 111b is operated in the shooting mode, the processing unit 111 is further configured to transmit a second warning notification to the terminal when determining that the human body meets a second predetermined condition according to the image data. Device 120. The second predetermined condition includes the body temperature of the human body being below a predetermined low temperature threshold. Thus, when the patient loses temperature, the medical staff holding the terminal device 120 can take appropriate countermeasures against the patient in time.

In summary, the monitoring system 110 can transmit the first alert notification to the terminal device 120 by determining that the human body in the image data generated by the image capturing module 111b meets the first predetermined condition, so that the holding or operating can be notified in time. The medical staff or family members of the terminal device are advantageous for emergency treatment. In addition, the power supply unit 111d can effectively utilize the light energy generated by the 24-hour fluorescent lamp in the hospital to achieve the effect of power saving.

The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the present invention are intended to be included in the scope of the appended claims.
