The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1 and fig. 2 together, fig. 1 is a flowchart illustrating a method for implementing emergency positioning based on a handheld terminal according to a first embodiment of the present invention, and fig. 2 is a schematic structural diagram illustrating a system for implementing emergency positioning based on a handheld terminal according to an embodiment of the present invention, wherein the method of fig. 1 is described on the system for implementing emergency positioning based on a handheld terminal of fig. 2. As shown in fig. 2, the emergency location system 1 of the present embodiment includes: a hand-held terminal 10, an emergency processing center 11, an auxiliary information processing system 12, a fire fighting system 13, a base station 14, a short message gateway 15 and an AML (Advanced Mobile Location, Chinese) server 16. The handheld terminal 10 includes, but is not limited to, a smart phone, a personal digital assistant, a tablet computer, an iPad, and the like. The emergency processing center 11 includes, but is not limited to, an emergency processing center of a hospital, a public security bureau, and a fire department, and is configured to answer an emergency call, make a corresponding instruction according to call content of the emergency call, and assign corresponding manpower or material resources for rescue. The auxiliary Information processing System 12 (hereinafter, referred to as "Enhanced Information System") may process Information such as GPS (Global Positioning System in chinese), WiFi, and base stations, perform calculation according to the Information such as GPS, WiFi, and base stations to determine an optimal Positioning result, generate a geographical image or text for display, and make a rescue plan through a specific algorithm. The fire protection system 13 includes, but is not limited to, a rescue device such as a fire truck, an ambulance, a police car, a ship, and the like. The AML server 16 is an advanced mobile positioning server, and can precisely position information such as GPS, WiFi, and base station through the handheld terminal 10 to generate a final positioning result, or transmit raw data of information such as GPS, WiFi, and base station to the auxiliary information processing system 12 for processing by using an operator network, and can store data, filter illegal information, and transmit data to EIS. In addition, the AML server 16 is an enhancement to traditional emergency voice positioning that provides a positioning accuracy of up to 5 meters, and in the worst case, a range of about 1.75 kilometers in radius.
As shown in fig. 1, the method for implementing emergency positioning based on a handheld terminal of this embodiment includes:
s11: and when the handheld terminal is in an emergency telephone call state, the voice call content of the handheld terminal user is sent to an emergency processing center.
When a user of the handheld terminal encounters an emergency, the user can dial the telephone number of the emergency processing center 11 through the handheld terminal 10 to ask the emergency processing center 11 for help in a voice call mode, such as dialing 119 when encountering a fire danger, dialing 110 when encountering kidnapping and the like to alarm and ask for help. When the user communicates with the handheld terminal 10, the emergency processing center 11 queries the current location of the user from the user to obtain the current location information of the user for rescue.
In the present embodiment, the hand-held terminal 10 transmits the contents of the voice call of the hand-held terminal user to the emergency processing center 11 through the base station 14 while in the emergency phone call state.
S12: and the handheld terminal synchronously starts a positioning function to acquire the current geographic position information of the handheld terminal when in an emergency telephone conversation state, and sends the geographic position information to the auxiliary information processing system through the short message.
The hand-held terminal 10 automatically triggers the location function when in an emergency phone call state. Preferably, the location function is initiated at the same time that the user places the emergency call. The current geographical position information of the handheld terminal 10 is obtained through the positioning function, and the geographical position information is sent to the auxiliary information processing system 12 through a short message, so that the auxiliary information processing system 12 positions the handheld terminal 10 according to the geographical position information and stores the positioning position.
The positioning functions of the handheld terminal 10 include, but are not limited to, base station positioning, WiFi positioning, GPS positioning, and thus the current geographic location information includes, but is not limited to, current base station location information, current WiFi location information, or current GPS location information. As shown in fig. 3, step S12 includes the further steps of:
s21: the base station location function is initiated.
S22: and starting the WiFi positioning function.
S23: and starting a GPS positioning function, and judging whether to acquire the current GPS position information within preset time.
The handheld terminal 10 turns on the base station positioning function, the WiFi positioning function, and the GPS positioning function at the same time when making an emergency call, and these three functions may be turned on at the same time or sequentially, which is not limited herein. The three positioning modes, i.e., the base station, the WiFi and the GPS, may call an Application Programming Interface (API) of the system to obtain the positioning information or obtain the positioning information through a software library ready by a third party, which is not described herein again. Therefore, the current base station position information of the handheld terminal 10 can be acquired through the base station 14, the current WiFi position information of the handheld terminal 10 can be further acquired through the WiFi positioning function, and the WiFi positioning function is turned off immediately after the current WiFi position information is acquired, so that the electric quantity can be saved, and the call of the rescuee can be kept under the emergency condition. However, because GPS positioning requires a longer time and consumes more power, in this embodiment, a time threshold is also preset, and the handheld terminal 10 further determines whether to acquire the current GPS location information within the preset time, if so, the process goes to step S24, and if not, the process goes to step S25.
S24: and the handheld terminal sends the current base station position information, the current WiFi position information and the current GPS position information to the auxiliary information processing system through short messages and closes the positioning function.
Within a preset time threshold, if the handheld terminal 10 successfully acquires the current GPS location information, the handheld terminal 10 packages the current base station location information, the current WiFi location information, and the current GPS location information and sends the current base station location information, the current WiFi location information, and the current GPS location information to the auxiliary information processing system 12 through a short message, and immediately turns off the GPS positioning function after acquiring the current GPS location information, so as to save electric power.
The handheld terminal 10 further processes the current location information of the base station, the current WiFi location information, or the current GPS location information to obtain an optimal positioning information result. The handheld terminal 10, such as a smart phone, processes the three positioning data by using a processing algorithm in the prior art, for example, an optimal positioning result is directly obtained according to the three positioning modes by a Google-carried tool under an android platform, which is not described herein again. In other embodiments, one or more of the current base station location information, the current WiFi location information, or the current GPS location information may also be sent to the assistant information processing system 12, and the assistant information processing system 12 processes the one or more data to obtain an optimal positioning result as the positioning location and stores the optimal positioning result.
S25: and the handheld terminal sends the current base station position information and the current WiFi position information to the auxiliary information processing system through the short message and closes the positioning function.
If the handheld terminal 10 fails to acquire the current GPS location information within the preset time threshold, only the current base station location information and the current WiFi location information are sent to the auxiliary information processing system 12, and after sending the short message, the positioning function is turned off to save electric power and ensure that the rescuee can make an emergency call. In other embodiments, only part of the successfully acquired location information may be sent to the auxiliary information processing system 12, and if no valid geographic location information is acquired in any of the three times of positioning, the positioning information is also sent to the auxiliary information processing system 12, so that the auxiliary information processing system 12 can immediately send information to the fire center 13, and the fire center 13 can quickly know that the current positioning is not successful, thereby wanting to know the geographic location of the rescuee through voice call or other means.
In this embodiment, as shown in fig. 4, the step of sending the geographical location information to the auxiliary information processing system 12 by the handheld terminal 10 through a short message further includes:
s31: and the handheld terminal sends the short message to the short message gateway through the base station.
S32: and the short message gateway forwards the short message to the AML server.
S33: the AML server further sends the short message to the auxiliary information processing system.
The handheld terminal 10 sends a short message to the short message gateway 15 through the base station 14, so that the position data of the base station 14 can be obtained. The short message gateway 15 forwards the short message to the AML server 16, where the AML server 16 is mainly used for storing AML data, where the AML server 16 stores one or more of current base station location information, current WiFi location information, or current GPS location information sent by the handheld terminal 10, or stores optimal positioning result data processed by the handheld terminal 10, filters illegal data, and sends the filtered data to the auxiliary information processing system 12, so that the auxiliary information processing system 12 further optimizes the data, thereby providing a positioning information with higher accuracy and more reliability.
In this embodiment, since the short message has the characteristics of wide coverage, high reliability, long-distance transmission, and the like, sending the positioning location information in the short message mode is an ideal choice. The short message gateway 15 belongs to an operator network and is responsible for forwarding the current geographical location information, and when the handheld terminal 10 is in an arrearage state, the operator network also can support forwarding of AML information (provided by an operator). In order to secure the life and property safety of the rescuee, when the handy terminal 10 is in the emergency phone call state, the contents of the voice call are transmitted to the emergency processing center 11 through the base station 14 regardless of whether the handy terminal 10 is in the defaulting state or not. Moreover, when the handheld terminal 10 is in the arrearage state, the current geographic location information may be sent to the short message gateway 15 by a short message, and the short message gateway 15 forwards the current geographic location information to the AML server 16, and the AML server 16 sends the current geographic location information to the auxiliary information processing system 12. It is noted that the positioning process of the geographic location information and the voice communication process are completely independent and can be performed simultaneously, so that the rescue command center can also quickly know the current geographic location of the rescuee under the condition that the rescuee is in a state of language obstruction or current geographic information cannot be described clearly, thereby quickly carrying out rescue and reducing the loss of lives and property of the rescuee.
S13: and the emergency processing center acquires the current position of the user according to the voice call content and sends the current position to the fire fighting system.
S14: the auxiliary information processing system sends the location position to the fire fighting system.
S15: and the fire fighting system determines an optimal rescue route according to the current position and the positioning position of the user.
In the embodiment, the emergency processing center 12 obtains the current location of the user according to the voice call content of the handheld terminal user, and sends the current location to the fire fighting system 13. Meanwhile, the auxiliary information processing system 12 also sends the positioning position to the fire fighting system 13, so that the fire fighting system 13 refers to four position messages, namely, the current position information of the user obtained according to the voice call, the current position information of the base station, the current WiFi position information and the current GPS position information provided by the auxiliary information processing system 12, and determines an optimal rescue route. In other embodiments, the auxiliary information processing system 12 may also perform optimization processing on the current base station location information, the current WiFi location information, and the current GPS location information in advance to obtain an optimal location position, and display the location position to the fire protection system 13 in the form of a geographical image, so that the fire protection system 13 can quickly make analysis and judgment according to the geographical image and the location described by the voice call to determine an optimal rescue route.
The implementation scenario of this embodiment is as follows:
when a user makes an emergency call (110, 119), the handheld terminal 10 detects the behavior, starts a positioning process, collects positioning information while the user is talking, sends the positioning information to the AML server 16 through a short message after the positioning information is completely collected, stores the positioning information in the AML server 16, sends the positioning information to the EIS 12 to select an optimal positioning result and presents the optimal positioning result to the fire fighting system 13 through images and texts, and the fire fighting system 13 makes a rescue scheme or directly arranges an optimal rescue path and a rescue mode through a specific algorithm.
In summary, in the method for implementing emergency positioning according to the embodiment, the handheld terminal user dials the emergency call to obtain the current position of the user, and the positioning function is simultaneously started to obtain the current geographic position information of the handheld terminal in the emergency call state to perform positioning to obtain the positioning position, so that the fire fighting system can quickly and accurately position the position of the rescued person by integrating the voice call and the positioning function, thereby determining the optimal rescue route and reducing the rescue time.
Referring to fig. 5, fig. 5 is a flowchart illustrating a method for implementing emergency positioning based on a handheld terminal according to a second embodiment of the present invention, which is further described in the method for implementing emergency positioning based on a handheld terminal according to the first embodiment. As shown in fig. 5, the method for implementing emergency positioning of the present embodiment includes:
s41: and the handheld terminal judges whether the electric quantity is lower than a preset threshold value when in an emergency telephone call state.
S42: the hand-held terminal only supports emergency call, and the voice call content of the hand-held terminal user is sent to the emergency processing center.
In this embodiment, when the handheld terminal user makes an emergency call in an emergency, the handheld terminal 10 simultaneously determines whether the power level is lower than a preset threshold, if so, step S42 is entered, the handheld terminal 10 only supports voice call, and the voice call content of the handheld terminal user is sent to the emergency processing center 11 through the base station 14. If not, the process proceeds to step S43.
Through the judgment of the electric quantity, only the emergency call is supported when the electric quantity is lower than a preset threshold value, and the positioning function is not started to save the electric quantity, so that the rescuee can keep talking.
S43: and the handheld terminal synchronously starts a positioning function to acquire the current geographical position information of the handheld terminal when in an emergency telephone conversation state.
S44: and judging whether the handheld terminal acquires the current geographic position information within a preset second time.
When the user of the handheld terminal makes an emergency telephone call and the power of the handheld terminal 10 is higher than or equal to a preset threshold value, the handheld terminal 10 automatically triggers a positioning function to obtain the current geographic location information of the handheld terminal 10. And further determines whether the handheld terminal 10 acquires the current geographic location information within a preset second time. If yes, the process proceeds to step S45. If not, the process proceeds to step S46.
In other embodiments, if the handheld terminal 10 re-places the emergency call after the second time has elapsed, the handheld terminal 10 restarts the location function to obtain the current geographic location information. If the hand-held terminal 10 re-dials the emergency call within the second time range, the positioning function is not restarted since the hand-held terminal 10 is still in the process of positioning.
S45: the handheld terminal judges whether the network service exists.
If the handheld terminal 10 acquires the current geographical location information within the preset second time, further determining whether the handheld terminal 10 has a network service, if so, entering step S46, and if not, entering step S47.
S46: and the handheld terminal sends the geographical position information to the auxiliary information processing system through the short message.
Wherein, if the handheld terminal 10 has network service, the geographical location information is sent to the auxiliary information processing system 12 by short message.
If the handheld terminal 10 does not obtain the current geographic location information within the preset second time, the handheld terminal 10 still sends the geographic location information to the auxiliary information processing system 12 through the short message. It should be noted that the content of the short message that does not acquire the geographical location information is not consistent with the content of the short message that acquires the geographical location information, and the short message that acquires the geographical location information may display the current geographical location information, for example, by displaying a geographical image or by displaying a field. The content of the short message for which the geographical location information is not acquired is displayed as "no information", so that the auxiliary information processing system 12 can acquire the location information of the rescuee from the content of the voice call or by other means according to the content of the short message.
S47: the handheld terminal judges whether the network service exists or not in a preset first time.
If it is detected that the handheld terminal 10 does not currently have the network service, it is further determined whether the handheld terminal 10 has the network service within a preset first time, and if so, the process goes to step S46 to send the geographical location information to the auxiliary information processing system 12 through a short message. If not, the process proceeds to step S48.
S48: and deleting the geographical position information by the handheld terminal.
If the handheld terminal 10 determines that there is no network service within the preset first time, the handheld terminal 10 deletes the geographic location information to avoid that the geographic location information loses the reference value for a long time after being retained.
For example, if the handheld terminal 10 does not currently have a network service, a time of 30 minutes is preset, and if the handheld terminal 10 still does not have a network service within the preset time of 30 minutes, the handheld terminal 10 deletes the acquired geographic location information, and may acquire the current geographic location information of the rescuee in other manners, such as restarting the positioning function.
S49: and the emergency processing center acquires the current position of the user according to the voice call content and sends the current position to the fire fighting system.
S50: the auxiliary information processing system sends the location position to the fire fighting system.
S51: and the fire fighting system determines an optimal rescue route according to the current position and the positioning position of the user.
When the handheld terminal 10 is in an emergency telephone call state, the voice call content of the user of the handheld terminal is sent to the emergency processing center 11, and when the emergency processing center 11 communicates with the handheld terminal 10 1, the current position of the user is inquired of the user, and the current position of the user is further sent to the fire fighting system 13. In addition, the auxiliary information processing system 12 also sends the location position to the fire fighting system 13, so that the fire fighting system 13 obtains an optimal location result according to the current position and the location position of the user, thereby determining an optimal rescue route.
Such as an optimal location result information obtained based on the Android platform (in chinese: Android), which can be uploaded to the AML server 16, can be composed of a plurality of fields, each of which contains a field name, a field value, a delimiter, etc., as follows:
