[0002] In the published Chinese patent application, publication number: CN210270172U, patent name: A farm machinery positioning system based on the Internet of Things, although the prior art receives GPS message information through the main controller and parses the current longitude and latitude, speed, and obtains the longitude and latitude information and speed information of the farm machinery to be located, the main controller processes the current longitude and latitude and speed information of the farm machinery to be located according to the communication protocol and sends it to the communication module, the communication module uploads the processed information to the cloud server, and the cloud server stores the information. The prior art uses GPS for position positioning, and after obtaining the position information, the position information is transmitted to the cloud server through the communication module, thereby achieving the effect of position positioning. However, the prior art uses a single GPS to implement positioning. Since most of the elderly and young users are in indoor places, the accuracy of position positioning in indoor places is relatively low, which is not suitable for accurate positioning of elderly and young users.

[0003] In the published Chinese patent application, publication number: CN210533430U, patent name: A manhole cover safety monitoring system, although the existing technology can accurately locate the manhole cover through the positioning unit, and can accurately detect and calculate the posture angle of the manhole cover, it also adds functions such as toxic gas detection, underground environment prediction, mesh safety self-locking device based on toxic gas detection, data compression and transmission, and system low power consumption. However, the existing technology mainly uses Beidou / GPS dual-mode positioning module to achieve position positioning, which still has the above-mentioned problems. GPS is used for positioning.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0019] See also Figure 1 to Figure 2 The utility model provides a technical solution: a device for indoor positioning of a ward, which is worn on the wrist of the ward, and includes a shell 1, and grooves 11 are provided on the side walls at both ends of the shell 1, and support bars 12 are fixedly connected at both ends of the shell 1 and located in the grooves 11, and straps 2 for binding the wrists of the ward are provided on the two support bars 12.

[0020] The indoor positioning device for the guardian shown in the application can be tied to the wrist of the guardian through a strap 2. The outer wall of the indoor positioning device for the guardian can be engraved with the guardian's information, such as the guardian's home address, the guardian's name, the guardian's telephone number, etc., so as to prevent the outside helpers from not being able to obtain the relevant information of the guardian in time after the guardian is lost.

[0021] A button hole 3 is provided on the upper surface of the housing 1, and a button 4 is fixedly installed inside the housing 1 and near the button hole 3. A control board 5 is fixedly installed on the inner wall of the housing 1, and the sensing element on the back of the button 4 is electrically connected to the control board 5 through a wire. A GPS receiver 10 and a WIFI module 6 are respectively arranged inside the housing 1, and the GPS receiver 10 and the WIFI module 6 are both connected to the control board 5 through communication. The GPS receiver 10 is used to collect GPS message information containing current longitude and latitude and speed data, and transmit it to the control board 5. The WIFI module 6 is connected to at least one wireless router in communication and obtains a communicative network environment. The control board 5 queries the longitude and latitude information of the wireless router through the lbsLoc.request() function, and obtains the longitude and latitude information of at least one wireless router by calling the getMyLocCb() callback function.

[0022] Among them, the button 4 is placed inside the housing 1, and the touch end of the button 4 is slightly lower than the outer surface of the housing 1 to prevent the ward from accidentally touching the button 4. The control board 5 is equipped with software programs such as logic control programs and timing control programs to meet the implementation needs of the device shown in this application. The control board 5 can use a microprocessor or a single-chip microcomputer. The WIFI module 6 is used to enable the device shown in this application to communicate with at least one wireless router in the room where the ward is located, so that the device shown in this application can obtain a network environment for communication.

[0023] After obtaining a communicable network environment, the device shown in the present application obtains two types of location information. Among them, the GPS receiver 10 is used to collect GPS message information containing current longitude and latitude and speed data, and transmit it to the control board 5, so as to obtain location information A. The control board 5 queries the longitude and latitude information of the wireless router through the lbsLoc.request() function, and obtains at least one longitude and latitude information of the wireless router by calling the getMyLocCb() callback function. When the device shown in the present application is connected to multiple wireless routers for communication, the longitude and latitude information of the wireless routers of multiple wireless routers will be obtained, and one or more wireless router location information constitutes location information B. After the control board 5 obtains the location information A and the location information B, the two location information are compounded to obtain high-precision location information, which is also the indoor location of the ward, so as to obtain the precise location of the ward. The control board 5 transmits the location information of the ward to the guardian client, and the guardian can obtain the location of the ward in time.

[0024] Button 4 is used for the ward to subjectively send location information to the guardian, which can not only allow the guardian to obtain the location, but also achieve the effect of alarm. After the ward presses button 4, the control panel 5 sends the location to the guardian's client.

[0025] Specifically, a temperature sensor 9 and a pulse sensor 8 are fixedly mounted on the inner wall of the housing 1. The temperature sensor 9 and the pulse sensor 8 are both connected to the control board 5 for communication. The sensing elements of the temperature sensor 9 and the pulse sensor 8 are located on the bottom wall of the housing 1 and close to the wrist of the person being supervised. A waterproof film is provided on the sensing elements of the temperature sensor 9 and the pulse sensor 8. The waterproof film is used to achieve a waterproof effect.

[0026] Among them, the temperature sensor 9 is used to detect the body temperature of the ward. When the ward's body temperature rises and is in a feverish or sick state, the temperature sensor 9 sends a relevant electrical signal to the control board 5. The control board 5 responds to the temperature sensor 9. The control board 5 sends the ward's location information to the guardian client. After the guardian obtains the location information, the guardian further processes the alarm. The guardian can know in time whether the ward has a fever or is sick. The pulse sensor 8 is used to detect the pressure change when the ward's pulse beats, that is, to obtain the change in the ward's pulse beat, and to judge the ward's heart beat by the pulse beat frequency. When the pulse beat frequency reaches the set threshold, it is determined that the ward's heart is uncomfortable. The pulse sensor 8 sends a relevant electrical signal to the control board 5. The control board 5 responds to the pulse sensor 8. The control board 5 sends the ward's location information to the guardian client. After the guardian obtains the location information, the guardian further processes the alarm. The guardian can know in time whether the ward is unwell.

[0027] Specifically, an accelerometer 7 is disposed in the housing 1 , and the accelerometer 7 is communicatively connected to the control board 5 .

[0028] Among them, the accelerometer 7 is used to detect the acceleration change and motion state of the device shown in this application, so as to obtain the motion state of the ward, and then determine whether the ward has fallen. At the moment of falling, the device shown in this application worn by the ward moves rapidly. When the accelerometer 7 in the device shown in this application detects that the speed change in a short period of time reaches the set threshold, the accelerometer 7 sends a corresponding electrical signal to the control board 5, and the control board 5 responds to the accelerometer 7. The position information of the control board 5 is transmitted to the guardian client, and the guardian can know the location of the ward in time, and can take corresponding measures in time to ensure the safety of the ward.

[0029] Specifically, a battery pack 13 is fixedly installed inside the housing 1 , and the battery pack 13 is respectively connected to the control board 5 , the temperature sensor 9 , the pulse sensor 8 , the GPS receiver 10 , and the accelerometer 7 through conductive wires.

[0030] The battery pack 13 is used to supply power to the control board 5 , the temperature sensor 9 , the pulse sensor 8 , the GPS receiver 10 , and the accelerometer 7 .

[0031] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
