With the development of technology, positioning systems with better accuracy are also on the market, however, there is a problem in integration between new and old systems, and therefore, it is common to set new positioning systems in the same field in a manner of replacing old positioning systems with new positioning systems, so that the old positioning systems cannot be continuously utilized, and transceivers need to be more densely set when setting new positioning systems, thereby increasing the cost. In addition, in some cases, existing positioning systems may determine the location of an electronic device held by a medical person, and in some cases, the electronic device may be operated by the medical person to issue an alarm, and after the emergency condition is resolved, the electronic device issuing the alarm may not be systematically managed.

Fig. 1 illustrates an exemplary operational scenario of an event state management system 110, including a block diagram of components of the event state management system 110, and a plurality of terminal devices 120 in data connection with the event state management system 110, according to some embodiments of the present disclosure. In other operating environments, the number of terminal devices 120 connected to the event state management system 110 is not limited to that disclosed in fig. 1.
In the embodiment, the event management system 110 may include a first electronic device 111', a second electronic device 111, a first location system 112, a second location system 113, a communication module 114, a database 115, a display unit 116, a processing unit 117, an input unit 118, and a first event database 119.
In another embodiment, the number of the first and second electronic devices 111', 111 may be two or more.
In this embodiment, the first (second) electronic device 111' (111) is implemented as a wearable device that can be worn on a subject. In one use case, the body carrying the first (second) electronic device 111' (111) can be moved within a field. In the use case, the field may be the first floor of a hospital. The body may be a human body, a device, or a mobile device. In the use case, the first electronic device 111' is worn by doctor a, and the second electronic device 111 is mounted on an emergency equipment that can be moved on the first floor.
In this embodiment, the first electronic device 111 ' has an operation element 111 ' a and an output module 111 ' B, and the first electronic device 111 ' sends a transmission signal and an alarm signal when the operation element 111 ' a is operated. In some cases, the operating element 111' a may be implemented as a button.

In this embodiment, the transmission signal indicates the identity data of the first electronic device 111'. In some cases, the identity data of the first electronic device 111 'may be a tag of the first electronic device 111'. In some cases, the tag is a "1".
In this embodiment, the second electronic device 111' continuously and intermittently sends a transmission signal. Intermittent signaling (i.e., non-continuous) is suitable for applications that are sensitive to power consumption, such as mobile devices operating on their own batteries. In this embodiment, the second electronic device 111 sends a transmission signal every transmission time interval. In some cases, the transmission time interval may be one second. In this embodiment, the transmission signal indicates the identity data of the second electronic device 111. In some cases, the identity data of the second electronic device 111 may be a tag of the second electronic device 111. In one use case, the tag is "2".
In this embodiment, the first location system 112 may include a plurality of first transceivers 112A, a first positioning engine 112B, and a database 112C.
The first transceivers 112A are disposed in the field at intervals. Each first transceiver 112A is configured to receive a transmission signal and an alarm signal from the first electronic device 111' and a transmission signal from the second electronic device 111. In this embodiment, the first transceiver 112A is disposed in a first positioning range of the field, so that the first transceiver 112A can receive the transmission signal from the first (second) electronic device 111 ' (111) and the alarm signal from the first electronic device 111 ' only when the first (second) electronic device 111 ' (111) is located in the first positioning range. In a usage scenario, the first location range is, for example, ward a, ward B, ward C, ward D, ward E, and ward F of the floor.
Each first transceiver 112A generates a Received Signal Strength Indicator (RSSI) according to the transmission Signal when receiving the transmission Signal, and transmits the RSSI, identity data indicating the identity of the first transceiver 112A, and identity data indicating the identity of the first (second) electronic device 111' (111) to the first positioning engine 112B.
In addition to the location or coordinates on the surface, the first transceiver 112A and the floor height may also be recorded when the first transceiver 112A is configured, and these data are stored in a database (e.g., database 112C) used by the first positioning engine 112B as a reference for positioning.
The first positioning engine 112B may be an electronic module comprising the necessary hardware, software, or firmware configured to communicate with the first transceiver 112A and configured to generate first location data corresponding to the first (second) electronic device 111 '(111) based on the RSSI received from the first transceiver 112A, identity data indicating the identity of the first transceiver 112A, and identity data indicating the identity of the first (second) electronic device 111' (111), and store the first location data to the database 112C. In this embodiment, the first position data not only indicates the floor height data corresponding to the field, the identity of the first (second) electronic device 111 '(111), and the location of the first (second) electronic device 111' (111) in the field, but also indicates the first timestamp. Following the aforementioned usage scenario, the first location data corresponding to the first electronic device 111 ' indicates the tag "1" of the first electronic device 111 ' and the coordinates of the first electronic device 111 ', and indicates "first floor" (floor height data).
In this embodiment, the second location system 113 may include a plurality of second transceivers 113A, a second positioning engine 113B and a database 113C.
The second transceivers 113A are disposed in the field at intervals, and each second transceiver 113A is configured to receive the transmitted signal from the second electronic device 111. In this embodiment, the second transceiver 113A is disposed in a second positioning range of the field, so that the second transceiver 113A can receive the transmitted signal from the second electronic device 111 only when the second electronic device 111 is located in the second positioning range. In the aforementioned use scenario, the second location range is, for example, the A, C, E patient room of the floor. Thus, in the aforementioned use scenario, the first positioning range and the second positioning range have an overlapping region, A, C, E wards, and the first positioning range is different from the overlapping region, B, D, F wards. It should be noted that, although the foregoing usage scenarios have been described as examples where the first positioning range covers the second positioning range, in other usage scenarios, the second positioning range may not be covered by the first positioning range.
Each second transceiver 113A generates an angle signal according to the transmission signal when receiving the transmission signal from the second electronic device 111, and transmits the angle signal, the identity data indicating the identity of the second transceiver 113A, and the identity data indicating the identity of the second electronic device 111 to the second positioning engine 113B, so as to position the second electronic device 111.
The second receiver 113A uses an Angle of Arrival (AOA) method to locate the second electronic device 111. Unlike the first transceiver 112A, the second receiver 113A has a built-in antenna with directivity, and the first transceiver 112A uses an antenna without directivity. When a second receiver 113A receives the transmission signal of the second electronic device 111, an angle signal is generated, and another second receiver 113A also generates another angle signal at the same time when receiving the transmission signal of the second electronic device 111, the second positioning engine 113B determines a straight line with the second receiver 113A as a starting point on a 2D plane according to the angle signals transmitted by at least two second receivers 113A and the height data of the two second receivers 113A, and an intersection point of the two straight lines is the position of the second electronic device 111.
In addition to the position or coordinates of the second receiver 113A on the floor, the height of the second receiver 113A and the floor must be recorded when the second receiver 113A is deployed, and the data is stored in a database (e.g., database 113C) used by the second positioning engine 113B as a reference for positioning.
The second positioning engine 113B may be an electronic module containing the necessary hardware, software, or firmware and configured to generate a second location data corresponding to the second electronic device 111 based on the angle signal received from the second transceiver 113A, the identity data indicative of the identity of the second transceiver 113A, and the identity data indicative of the identity of the second electronic device 111, and store the second location data to the database 113C. The second location data not only indicates the floor height data corresponding to the field, the identity of the second electronic device 111, and the location of the second electronic device 111 in the field, but also indicates a second timestamp. Following the aforementioned usage scenario, the second location data corresponding to the second electronic device 111 indicates the tag "2" of the second electronic device 111 and the coordinates of the second electronic device 111, and indicates "first floor" (floor height data).
In the present embodiment, the first location system 112 is different from the second location system 113. In the embodiment, the first location system 112 can receive the transmission signals from the second electronic device 111 and the first electronic device 111 ', and the second location system 113 can receive the transmission signal from the second electronic device 111 but can not receive the transmission signal from the first electronic device 111'. In some cases, the cost of the second location system 113 is relatively higher than the cost of the first location system 112, and the accuracy of the second location data generated by the second location system 113 is relatively higher than the accuracy of the first location data generated by the first location system 112.
In this embodiment, the communication module 114 may be an electronic module including necessary hardware, software, or firmware configured to connect to the first location system 112 and the second location system 113 via a suitable communication network 130 and configured to connect to the end device 120 via a suitable communication network 140, wherein the suitable communication network 130(140) may include at least one of wired and wireless media.
The database 115 may include one or more storage devices configured to store the identity data of the first and second electronic devices 111 ', 111, a plurality of identity data corresponding to a plurality of subjects wearing the first and second electronic devices 111', 111, respectively, and a plurality of plan view data. The identity data of the first (second) electronic device 111 '(111) uniquely corresponds to said first (second) electronic device 111' (111). In some cases, the identity data of the first (second) electronic device 111' (111) is a tag. Following the previous example, the label corresponding to the second electronic device 111 is "2", and the label corresponding to the first electronic device 111' is "1". In the present embodiment, the identity data of the first (second) electronic device 111' (111) corresponds to one of the identity data of the subject. Following the previous example, the identification data of the subject corresponding to the label "2" indicates "emergency equipment", and the identification data of the subject corresponding to the label "1" indicates "doctor a". In the present embodiment, each piece of plan view data is associated with a plan view of a field.
The display unit 116 is, for example, a display screen.
The processing unit 117 is in data connection with the communication module 114, the database 115, the display unit 116, and the input unit 118. The processing unit 117 may be an electronic module, such as a server, that includes one or more hardware, software, or firmware. The servers may be in a centralized configuration or in a decentralized cluster arrangement. The processing unit 117 is configured to read the first and second location data stored in the first and second location systems 112 and 113 respectively corresponding to the second electronic device 111 and the first location data stored in the first location system 112 corresponding to the first electronic device 111' via the communication module 114 every predetermined period. In the present embodiment, the predetermined period may be 1 second. The processing unit 117 is configured to determine one of the first and second read position data as current position data. The processing unit 117 is further configured to store the determined current location data in the database 115. In some cases, the processing unit 117 is configured to replace the current location data already stored in the database 115 with the current location data.
The processing unit 117 is configured to control the content displayed by the display unit 116. In the present embodiment, the processing unit 117 is configured to control the display unit 116 to display the plan view of the field and the position of the first (second) electronic device 111' (111) in the plan view according to the plan view data and the current position data read from the database 115.
In this embodiment, the processing unit 117 is configured to return a location reply in response to a location request from one of the terminal devices 120 and corresponding to one of the first and second electronic devices 111', 111. The location reply is related to the current location data and the plan view data corresponding to the one of the first and second electronic devices 111', 111. In this embodiment, the location request indicates the identity data of the one of the first and second electronic devices 111', 111, so that the processing unit 117 can select the corresponding plan view data, the corresponding identity data of the main body, and the current location data.
On the other hand, when receiving the alarm signal from the first electronic device 111 ', the first location system 112 transmits the alarm signal to the processing unit 117, so that the processing unit 117 causes the display unit 116 to display the location of the first electronic device 111' in the field and an alarm related to the alarm signal according to the current location data and the alarm signal. In one embodiment, after the emergency situation is resolved, the background (for example, the processing unit 117) issues an emergency information resolving command, and sends the command to the first electronic device 111 'sending the information through the first transceiver 112A, so as to instruct the first electronic device 111' to resolve the emergency signal, so that the output module 111 'B of the first electronic device 111' does not send an alarm signal. In the embodiment, when the first electronic device 111' does not receive the emergency information release instruction, the transmission of the transmission signal and the alarm signal is stopped for ten minutes.
In the present embodiment, the input unit 118 is configured for manual operation. In some embodiments, the input unit 118 may include a keyboard or a touch panel.
In the present embodiment, the first event database 119 is configured to store a plurality of files. The files respectively correspond to the first electronic devices 111'. Each file indicates a state of the corresponding first electronic device 111'. In some embodiments, each profile may indicate that the corresponding first electronic device 111' is in the first state or the second state. In one case, the first state may represent that the body wearing the first electronic device 111 'is in an emergency state, and the first state may represent that the body wearing the first electronic device 111' is in a non-emergency state.
In the present embodiment, the terminal device 120 is configured to be in data connection with the event management system 110 via a communication network 140. The terminal device 120 is configured to transmit a location request corresponding to one of the first and second electronic devices 111', 111 to the processing unit 117. In some cases, the terminal device 120 is configured to display a plan view, a corresponding position of the first (second) electronic device 111 '(111) in the plan view, identity data of a subject wearing the first (second) electronic device 111' (111), and a timestamp in the current position data according to the position reply received from the processing unit 117. In some cases, the terminal device 120 may be implemented as a smart phone, a notebook computer, a personal computer, or a tablet computer, etc. In the aforementioned use scenario, the terminal device 120 is held by medical personnel of the hospital.
Fig. 2 schematically shows a plan view 210 displayed by the terminal device 120. Following the previous example, the plan view presents the first floor corresponding to the hospital including the a ward, the B ward, the C ward, the D ward, the E ward, the F ward, and the image 211 presents the location of the a doctor wearing the first electronic device 111' in the plan view 210.
FIG. 3 illustrates a flow chart of a positioning procedure of an event state management method implemented by some illustrative event state management systems according to the present disclosure.
The positioning process is described below with reference to fig. 1 and fig. 3, and taking the second electronic device 111 as an example.
First, as shown in the process S301, the processing unit 117 reads first position data corresponding to the second electronic device 111 from the first position system 112 and second position data corresponding to the second electronic device 111 from the second position system 113.
In step S302, the processing unit 117 determines whether the second electronic device 111 is located in an overlapping area of the first positioning range covered by the first position system 112 and the second positioning range covered by the second position system 113. If so, i.e. the processing unit 117 determines that the second electronic device 111 is located in the overlapping area, the flow proceeds to step S303. If the result is negative, that is, the processing unit 117 determines that the second electronic device 111 is located in one of the first and second positioning ranges and is not located in the overlapping area, the process proceeds to step S304.
In this embodiment, in the process S302, the processing unit 117 determines that the second electronic device 111 is located in the overlapping region when it is determined that the time difference between the first and second timestamps indicated by the read first and second position data is not greater than a threshold time interval, and determines that the second electronic device 111 is not located in the overlapping region when it is determined that the time difference between the first and second timestamps is greater than the threshold time interval. In this embodiment, the threshold time interval is, for example, 1 second.
In the process S303, the processing unit 117 determines that the second position data corresponds to the current position data of the second electronic device 111. In other words, when the second electronic device 111 is not in the overlapping area, the processing unit 117 determines the second position data with higher accuracy as the current data.
In step S304, the processing unit 117 determines that the first or the second position data is the current position data based on selecting one of the first and the second time stamps which is closest to the current time.
Next, the processing unit 117 stores the current position data to the database 115 when determining the current position data.
The foregoing processes S301 to S304 are described below in an exemplary practical scenario.
In the actual situation, the first aid device equipped with the second electronic device 111 stays in ward a between 9 am and 10 am, and then leaves ward a and enters ward B at 10 am on the same day, and stays in ward B for 1 hour.
In the practical scenario, at 9 am, the transmission signal transmitted by the second electronic device 111 is received by the first location system 112 and the second location system 113, so that the first location system 112 and the second location system 113 respectively generate and store the first location data and the second location data corresponding to the second electronic device 111, and the first timestamp and the second timestamp of the first location data and the second location data respectively indicate "09: 00'.
In the actual situation, at 9 am, the processing unit 117 determines that the second electronic device 111 is located in the overlapped area in the process S301, and therefore the flow proceeds to the process S303, and the processing unit 117 uses the second location data as the current location data, so that the current location data indicates "first floor", "2", and "09: 00', and the coordinates of the second electronic device 111 in ward A.
In the actual scenario, at 10 am and half, the transmission signal sent by the second electronic device 111 will only be received by the first location system 112, so that the first location system 112 generates and stores first location data corresponding to the second electronic device 111, the first location data having a first timestamp indicating "10: 30'. Meanwhile, since the transmission signal transmitted by the second electronic device 111 cannot be received by the second location system 113 after 10 am, the second timestamp of the latest second location data stored by the second location system 113 indicates "10: 00'. Therefore, at 10 am, the processing unit 13 compares the latest first position data with the latest second position data, and determines that the first timestamp "10: 30 "and a second timestamp" 10: 00 "is 0.5 hours, which is greater than the threshold time interval, so that the process proceeds to step S304, the processing unit 117 uses the corresponding first location data as the current location data, so that the current location data indicates" first floor "," 2 "," 10: 30 ", and the coordinates of the second electronic device 111 in the B ward.
FIG. 4 sets forth a flow chart of an event state management program of the event state management method implemented by some illustrative event state management systems according to the present disclosure.
The positioning process is described below with reference to fig. 1 and 4, and taking the first electronic device 111' as an example.
First, as shown in step S401, the first location system 112 updates the file corresponding to the identity data of the first electronic device 111 'in the first event database when receiving the alarm signal from the first electronic device 111'. In some cases, when the main body wearing the first electronic device 111 'has an emergency and operates the operating element 111' a of the first electronic device 111 ', so that the first electronic device 111' sends an alarm signal, the first location system 112 updates the state of the file corresponding to the identity data of the first electronic device 111 'to indicate the first state, that is, the main body wearing the first electronic device 111' is in the emergency state.
Next, as shown in step S402, the input unit 118 causes the processing unit 117 to transmit update data to the first location system, where the update data indicates the identity data of the first electronic device 111'. In some cases, the guard releases the emergency situation of the main body wearing the first electronic device 111 ', and operates the input unit 118 to cause the processing unit 117 to read the first location system 112 and cause the first display unit 116 to display the state corresponding to the first electronic device 111'. Then, the operation input unit 118 causes the processing unit 117 to update the state indicated by the file.
Next, as shown in step S403, when receiving the update data from the processing unit 117, the first location system 112 updates a file corresponding to the identity data of the first electronic device 111 'in the first event database 119 according to the update data, and sends an emergency release command indicating the identity data of the first electronic device 111'. In some cases, the state indicated by the file is updated from the first state to the second state, i.e., the main body wearing the first electronic device 111' is in a non-emergency state.
Next, as shown in step S404, when receiving the emergency release information command sent from the first location system, the first electronic device 111' determines whether its identity data is identical to the identity data indicated by the emergency release information command. If so, the flow proceeds to the process S405, otherwise, the flow ends.
In the process S405, the output module 111 'B of the first electronic device 111' stops outputting. In some cases, the first electronic device 111 'turns off the LED lighting module included in the output module 111' B.
It should be noted that in other embodiments, the second location system 113 may also be connected to a second event database, so that the second location system 113 can also apply the aforementioned processes S401 to S405.
In summary, the first location system 112 updates a file corresponding to the identity data of the first electronic device 111 'in the first event database 119 when receiving the update data from the processing unit 117, and the first electronic device 111' stops outputting the output module 111 'B of the first electronic device 111' when determining that the identity data indicated by the emergency release information command received from the first location system 112 is identical to the identity data of the first electronic device 111 ', so as to systematically update the state of the first electronic device 111'. In addition, the processing unit 117 can determine whether the second electronic device 111 is located in the overlapping area according to the first and second timestamps, so as to determine one of the first and second location data as the current location data, thereby making full use of the first and second location systems 112 and 113 without removing the first location system 112 or the second location system 113, and further obtaining a preferred location of the second electronic device 111.
The foregoing is by way of example only, and not limiting. It is intended that all equivalent modifications or variations without departing from the spirit and scope of the present invention shall be included in the appended claims.
However, the above description is only a preferred embodiment of the present invention, and should not be taken as limiting the scope of the invention, which is defined by the appended claims and the description of the invention.
