Aiming at the problems that the traditional method for positioning the fire fighters is low in positioning precision and cannot effectively schedule the fire fighters, and further timely and effective rescue of commanders and the fire fighters is affected, the embodiment of the application provides the fire fighting scheduling method.

Referring to fig. 1, a system architecture diagram of a fire scheduling method according to an embodiment of the present invention may include at least three positioning base stations 10, at least one positioning terminal 20, and a monitoring scheduling platform 30. Fig. 1 is only an exemplary illustration, and the number of positioning base stations 10 and positioning terminals 20 is not limited.

The positioning base station 10 is configured to be disposed inside or outside a target space, determine a preliminary position based on satellite positioning, and correct the preliminary position by a transmission distance of a ranging signal between two pairs to obtain a final position.

The positioning terminals 20 are configured to broadcast position detection signals, receive response signals sent by each positioning base station 10 based on the position detection signals, determine the current position of each positioning terminal 20 based on the position detection signals, the response signals, and the final position of each positioning base station, obtain image information of the position, and send the current position and the image information to the monitoring scheduling platform 30.

The monitoring scheduling platform 30 is configured to generate scheduling information based on the current position and the image information sent by each positioning terminal 20, and send the scheduling information to the corresponding positioning terminal 20; the scheduling information comprises a positioning terminal identifier and a scheduling instruction.

Specifically, when fire rescue needs to be started in an emergency, a plurality of positioning base stations 10 can be quickly arranged in or outside a target space, the initial position of each positioning base station 10 is determined based on satellite positioning, and the initial position is corrected through the transmission distance of ranging signals between every two positioning base stations to obtain the final position of each positioning base station 10; the positioning terminal 20 in the target space can broadcast the position detection signal and receive the response signals returned by the plurality of positioning base stations 10, determine the current position based on the position detection signal response signal and the final position of each positioning base station 10, and can acquire the image information of the position and send the image information and the current position to the monitoring and scheduling platform 30; the monitoring and scheduling platform 30 can generate scheduling information based on the current position of each positioning terminal and the corresponding image information and send the scheduling information to the corresponding positioning terminal, so as to implement scheduling of fire fighters.

In one possible implementation, the process of determining the position of the positioning base station 10 may include the following steps:

in step a1, a preliminary position at the positioning base station is determined based on the satellite positioning, and a first distance between each of the positioning base stations is determined based on the preliminary position.

In this step, the preliminary positions of the at least three positioning base stations may be determined by one or more of a COMPASS satellite positioning system (COMPASS), a Global Positioning System (GPS), a GALILEO satellite positioning system (GALILEO), and a GLONASS satellite positioning system (GLONASS). For example, the preliminary location may include a longitude, latitude, and altitude at which the base station is located. In the embodiment of the present application, a Beidou satellite positioning system is taken as an example for explanation, but not limited thereto.

In one possible implementation, the preliminary location may include a longitude, latitude, and altitude; correspondingly, after the initial positions of at least three positioning base stations are determined, the first distance between any two positioning base stations can be calculated according to the longitude, the latitude and the altitude of the initial positions of any two positioning base stations.

It should be noted that the positioning base station in the embodiment of the present application needs to include a satellite positioning module corresponding to a satellite positioning system and a communication module for communicating with other external base stations.

In step B1, determining a second distance between each two of the at least three positioning base stations according to the transmission time of the ranging signal between each two of the at least three positioning base stations.

The second distance between the two positioning base stations is determined by combining the transmission time of the signals between the two positioning base stations and the transmission speed of the signals.

For example, a second distance between two positioning base stations may be determined based on a first time when a ranging signal is broadcast by a first positioning base station, a second time when a second positioning base station receives the first ranging signal, a third time when the second positioning base station sends a first response signal based on the first ranging signal, and a fourth time when the first positioning base station receives the first response signal, in combination with a signal transmission speed;

the first positioning base station is any one of the at least three positioning base stations, and the second positioning base station is a positioning base station of the at least three positioning base stations except the first positioning base station.

Illustratively, the first positioning base station may be according to S1_i＝c×[(T_i4-T_i1)-(T_i3-T_i2)]Calculating a second distance from the first positioning base station to each second positioning base station;

wherein, S1_iIs the second distance from the first positioning base station to the second positioning base station i, c is the propagation speed of the signal from the first positioning base station to each second positioning base station i, T_i4At a fourth time, T_i1At a first time, T_i3At a third time, T_i2Is the second time.

In step C1, the preliminary position of each positioning base station is corrected based on the first distance and the second distance, so as to obtain a second position of the positioning base station.

Illustratively, the preliminary location may include a first longitude, a first latitude, and a first altitude; the correcting the preliminary position according to the difference between the corresponding first distance and second distance may include:

determining a correction coefficient according to an average value of differences between a first distance and a second distance between any two positioning base stations;

and respectively correcting the first longitude, the first latitude and the first altitude in the initial position according to the correction coefficient to obtain the second position.

Referring to fig. 2, a schematic diagram of an application environment for determining a second position of a positioning base station is shown. Specifically, 4 positioning base stations are taken as an example for illustration, but the invention is not limited thereto. The positioning base station 1, the positioning base station 2, the positioning base station 3 and the positioning base station 4 are arranged outside the target space, the four positioning base stations can be respectively arranged at any position around the target space, and the four positioning base stations are not positioned on the same horizontal plane.

Specifically, the first distances between every two four positioning base stations are Di, the corresponding second distances are Si, i is 1,2, …, and 6, and the correction coefficient is

After the correction coefficient δ is obtained, the preliminary position of the positioning base station may be corrected by the correction coefficient δ.

For example, the longitude of the positioning base station may be corrected by a correction coefficient δ, the latitude of the positioning base station may be corrected by a correction coefficient δ, and the altitude of the positioning base station may be corrected by a correction coefficient δ, so as to obtain the final position of the positioning base station. Specifically, the longitude, latitude, and altitude in the initial position of the positioning base station may be respectively summed with the correction coefficient δ as the longitude, latitude, and altitude in the second position of the positioning base station.

The fire-fighting scheduling method of the present application is described in detail below with reference to fig. 1 and 2.

Fig. 3 is a schematic flowchart of a fire-fighting scheduling method according to an embodiment of the present application, where the fire-fighting scheduling method can be applied to a first positioning terminal, and the first positioning terminal is any one of the positioning terminals, and with reference to fig. 3, the fire-fighting scheduling method is described in detail as follows:

in step 101, a position detection signal is broadcasted, and a response signal based on the position detection signal transmitted by each positioning base station is received.

The positioning base stations are disposed inside or outside a target space, which may be, for example, an indoor space, such as a residential building, an office building, a public place, or the like.

Specifically, the first positioning terminal may broadcast a position detection signal in real time, and the position detection signal may be received by each positioning base station in the target space. After the positioning base stations receive the position detection signals, response signals corresponding to the position detection signals are generated and returned to the first positioning terminal, and the first positioning terminal receives the response signals sent by the positioning base stations.

The position detection signal may include a network position of the first positioning terminal, and is used to instruct the positioning base station to send a response signal to the first positioning terminal according to the network position; the response signal may include the location of the positioning base station and the positioning base station identifier, so as to instruct the first positioning terminal to determine the positioning base station corresponding to the response signal and the location of the positioning base station based on the location and the positioning base station identifier in the response signal.

It should be noted that each positioning base station in the target space may be preset inside or outside the target space, or may be disposed on site when performing fire rescue, which is not limited in this embodiment of the present application.

In step 102, a current location of the first positioning terminal is determined based on the location probe signal, the response signal and the locations of the respective positioning base stations.

In a possible implementation manner, referring to fig. 4, based on the embodiment shown in fig. 3, the determining the current location of the first positioning terminal based on the location detection signal, the response signal, and the locations of the respective positioning base stations may include:

in step 1021, distances between the first positioning terminal and at least three positioning base stations are determined based on the position detection signal and response signals of the at least three positioning base stations.

In this step, the distance between the first positioning terminal and the positioning base station may be determined based on the propagation speed of the signal according to the correlation time of the position detection signal and the correlation time of the response signal. For example, the distance between the first positioning terminal and the positioning base station may be determined based on the difference between the time when the first positioning terminal transmits the position detection signal and the time when the response signal is received, and then multiplied by the propagation speed of the signal.

Further, considering that a certain time difference exists between the time when the positioning base station receives the position detection signal and the time when the positioning base station sends the response signal, in order to more accurately determine the distance between the first positioning terminal and the positioning base station, the distance between the first positioning terminal and the positioning base station may be determined based on the difference between the time when the first positioning terminal sends the position detection signal, the time when the first positioning terminal receives the response signal, the time when the positioning base station receives the position detection signal, and the time when the positioning base station sends the response signal, and then multiplied by the propagation speed of the signal.

For example, the location probe signal may include a broadcast time of the first location terminal broadcasting the location probe signal, and the response signal may include a location station identifier, a first receiving time of the location base station receiving the location probe signal, and a first transmitting time of the location base station transmitting the response signal.

Correspondingly, the distance between the first positioning terminal and each positioning base station may be determined based on the broadcast time, the first receiving time, the first sending time, and the second receiving time when the first positioning terminal receives the response signal in each response signal, in combination with the transmission speed of the signal.

For example, this step may be based on S_i＝c×[(T_ia1-T_ia2)-(T_ib1-T_ib2)]Calculating the distance from the first positioning terminal to each positioning base station;

wherein S is_iIs the distance from the first positioning terminal to the positioning base station i, c is the propagation speed of the signal between the first positioning terminal and the positioning base station i (the propagation speeds of the position detection signal and the response signal are the same), T_ia1A second receiving time T of the first positioning terminal receiving the response signal sent by the positioning base station i_ia2For said broadcast time, T_ib1First transmission time, T, for transmitting response signal for positioning base station i_ib2A first reception time for the positioning base station i to receive the position detection signal.

In some embodiments, the broadcast time, the first sending time, the first receiving time, the second receiving time, and the positioning base station identifier may all be carried in the response signal, and the first positioning terminal only needs to extract the broadcast time, the first sending time, the first receiving time, the second receiving time, and the positioning base station identifier from the received response signal, determine the positioning base station, and calculate the distance to the positioning base station.

In some embodiments, the distance from the first positioning terminal to the positioning base station may be determined using an Ultra-wideband (UWB) signal, which is a communication technique that transmits data using nanosecond non-sinusoidal narrow-pulse signals. The UWB signal has the characteristics of short pulse interval and high time resolution, so that the ranging precision of centimeter level can be achieved by ranging through the UWB signal. In addition, the UWB signal has good robustness and penetration capacity to multi-path effect, and has great advantage in the indoor wireless positioning scene with dense obstacles. And the UWB signal can realize the data transmission rate of hundreds of Mbit/s to Gbit/s in the range of about 10 meters by transmitting a signal with extremely low power on a wider frequency spectrum, and the characteristics of higher data transmission rate of the 5G technology are combined, so that the data transmission delay is avoided, and the command system can receive the field information in real time.

For example, the signal flow between the first positioning terminal and each positioning base station may be as follows:

the first positioning terminal can broadcast a UWB position detection signal to the target space, wherein the UWB position detection signal carries the network address and the broadcast time of the first positioning terminal;

each positioning base station in the target space can detect the UWB position detection signal, a response signal is generated according to the UWB position detection signal and is sent to the first positioning terminal based on the network address, and the response signal carries broadcast time, first receiving time, first sending time, second receiving time and positioning base station identification;

and the first positioning terminal extracts the broadcast time, the first sending time, the first receiving time, the second receiving time and the positioning base station identification from the received response signal, determines the positioning base station and calculates the distance to the positioning base station.

In a possible implementation manner, the first positioning terminal and the positioning base station are both provided with a UWB positioning unit, and the UWB positioning unit can realize a ranging function from the first positioning terminal to the positioning base station and a ranging function between the positioning base stations.

In step 1022, a current location of the first positioning terminal is determined based on distances between the first positioning terminal and the at least three positioning base stations and locations of the at least three positioning base stations.

After the distances between the first positioning terminal and the at least three positioning base stations are obtained, the current position of the first positioning terminal can be determined by combining the positions of the positioning base stations. For example, the distance between the positioning base stations may be determined according to the positions of the positioning base stations, and then the current position of the first positioning terminal may be obtained by combining the distance between the first positioning terminal and each positioning base station and the positions of the positioning base stations.

Illustratively, step 1022 may be implemented by:

in step a2, distances between the respective positioning base stations are calculated based on the positions of the at least three positioning base stations.

For example, a coordinate system may be established based on three positioning base stations, distances between the three positioning base stations may be calculated, and a current location of the first positioning terminal may be determined.

For example, referring to fig. 5, the three positioning base stations are Ro, Rx, and Ry, coordinate axes are established by using the positioning base station Ro as an origin, a connection line between the positioning base station Ro and the positioning base station Rx as an x-axis, a connection line between the positioning base station Ro and the positioning base station Ry as a y-axis, and a vertical direction between the positioning base station Ro and the x-axis and the y-axis as a z-axis, and a distance l between the positioning base station Ro and the positioning base station Rx can be calculated according to position coordinates of the three positioning base stations_oxThe distance between the positioning base station Ro and the positioning base station Ry is l_oy。

Specifically, the positions of the positioning base stations Ro, Rx, and Ry may include longitude, latitude, and altitude, and after the positioning base station Ro is set as the origin, the position coordinate of the positioning base station Ro is (0,0,0), and the longitude, latitude, and altitude of the positioning base station Rx may be converted into a position coordinate based on the position coordinate of the positioning base station Ro, and the longitude, latitude, and altitude of the positioning base station Ry may be converted into a position coordinate; then, according to the position coordinates of the positioning base stations Ro, Rx and Ry, the distance l between the positioning base station Ro and the positioning base station Rx is calculated_oxAnd the distance l between the positioning base station Ro and the positioning base station Ry_oy。

It should be noted that, in this embodiment, three positioning base stations are taken as an example to define the process of determining the current position of the first positioning terminal, but the present invention is not limited thereto, and based on the following description, a person skilled in the art can determine the current position of the first positioning terminal based on four or more positioning base stations.

In step B2, a current location of the first positioning terminal is determined based on the locations of the at least three positioning base stations, the distances between the first positioning terminal and the respective positioning base stations, and the distances between the respective positioning base stations.

Referring to fig. 5, for example, the distance from the positioning base station Ro to the first positioning terminal is set to d_oThe distance from the positioning base station Rx to the first positioning terminal is d_xThe distance from the positioning base station Ry to the first positioning terminal is d_yAnd the position of the first positioning terminal in the coordinate system is (x, y, z), and then the distance l between the positioning base station Ro and the positioning base station Rx is combined_oxAnd the distance l between the positioning base station Ro and the positioning base station Ry_oyThen there is

From this, the position (x, y, z) of the first positioning terminal can be derived as:

in step 103, image information of an area where the first positioning terminal is located is obtained through an image acquisition unit of the first positioning terminal.

The first positioning terminal may include an image acquisition unit to acquire image information of an area where the first positioning terminal is located. For example, the image acquisition unit may be a camera. For example, the first certain terminal may be a mobile phone, and the position of the camera on the mobile phone may be front-located or rear-located, which is not limited in this embodiment of the application.

In step 104, the current position and the image information are sent to a monitoring scheduling platform, and scheduling information sent by the monitoring scheduling platform is received.

The monitoring and dispatching platform can identify the image information according to the image information and the current position sent by each first positioning terminal, determine the fire around each first positioning terminal, and is convenient for dispatching fire fighters and providing effective protective measures for the fire fighters.

By way of example, a sequence of infrared images of a flame during fire combustion tends to have the following identifiable characteristics: the adjacent images have unstable edges, certain similarity of image sequences and the like, so that the fire around the first positioning terminal can be identified through an infrared technology.

The monitoring and scheduling platform may convert the current position of each first positioning terminal into data corresponding to longitude, latitude, and altitude, or may convert the current position into data corresponding to a floor, a floor area (e.g., a room number), or the like. For example, each floor corresponds to a first coordinate range, and each room number corresponds to a second coordinate range, so that the floor where the first positioning terminal is located and the corresponding floor area can be determined according to the current position (x, y, z) of the first positioning terminal, the current position of each firefighter can be monitored visually, and the firefighters can be scheduled conveniently and effective protective measures can be provided for the firefighters.

Optionally, based on the embodiment shown in fig. 1, the fire-fighting scheduling method may further include:

For example, the first positioning terminal may include a smoke monitoring unit to obtain smoke concentration information of an area in which the first positioning terminal is located. For example, the smoke monitoring unit may be a smoke sensor.

By monitoring the smoke concentration information of the area where the first positioning terminal is located, effective protective measures can be provided for the safety of fire fighters. For example, smoke concentration within a certain range around the fire fighter exceeds a smoke concentration threshold (for example, the maximum concentration that can be borne by the human body), can produce smoke concentration early warning signal, carries out early warning suggestion to the fire fighter, can send current position and smoke concentration early warning signal to the positioning terminal that other fire fighters carried simultaneously, can remind or seek help other fire fighters.

In addition, the positioning terminal can send the smoke concentration information, the current position of the first positioning terminal and the first positioning terminal identification to the monitoring and dispatching platform in real time or at regular time, the monitoring and dispatching platform can monitor the fire condition of a target area in real time according to the smoke concentration and the current position around the fire fighter, and meanwhile, more effective protection measures can be provided for the fire fighter.

Illustratively, the first positioning terminal may include a physical sign monitoring unit to obtain physical sign parameters of the fire fighter. For example, the physical sign monitoring unit may acquire physical sign parameters of the firefighter through other intelligent devices worn by the firefighter, or may directly monitor the physical sign parameters of the firefighter, which is not limited in this embodiment of the present application.

The physical sign parameters of the firefighters are monitored, and effective protection measures can be provided for the safety of the firefighters. For example, when the physical sign parameter of the fire fighter exceeds the safety range, the physical sign early warning signal can be generated to carry out early warning prompt on the fire fighter, and meanwhile, the current position and the physical sign early warning signal can be sent to positioning terminals carried by other fire fighters, so that the fire fighters can be reminded or ask for help.

In addition, the positioning terminal can send the physical sign parameters, the current position of the first positioning terminal and the first positioning terminal identification to the monitoring and dispatching platform in real time or at regular time, and the monitoring and dispatching platform can dispatch fire fighters and provide more effective protective measures for the fire fighters according to the current physical sign parameters and the current position of the fire fighters.

In the embodiment of the application, the current position can be shared by other positioning terminals through broadcasting the information of the positioning terminals among the positioning terminals in the target space, so that fire fighters can freely form groups, share resources, quickly respond and process emergencies.

The following describes the signal transmission between the first positioning terminal, the positioning base station and the monitoring and scheduling platform with reference to fig. 6, which is detailed as follows:

a first positioning terminal broadcasts a position detection signal, wherein the position detection signal carries a network address and broadcast time of the first positioning terminal;

the positioning base station detects a position detection signal, generates a response signal based on the position detection signal and sends the response signal to the first positioning terminal according to the network address of the first positioning terminal, wherein the response signal carries broadcast time, a positioning base station identifier, first receiving time for the positioning base station to receive the position detection signal and first sending time for the positioning base station to send the response signal;

By way of example and not limitation, when the terminal device is a wearable device, the wearable device may also be a generic term for intelligently designing daily wearing by applying wearable technology, developing wearable devices, such as glasses, gloves, watches, clothing, shoes, and the like. A wearable device is a portable device that is worn directly on the body or integrated into the clothing or accessories of the user. The wearable device is not only a hardware device, but also realizes powerful functions through software support, data interaction and cloud interaction. The generalized wearable intelligent device has the advantages that the generalized wearable intelligent device is complete in function and large in size, can realize complete or partial functions without depending on a smart phone, such as a smart watch or smart glasses, and only is concentrated on a certain application function, and needs to be matched with other devices such as the smart phone for use, such as various smart bracelets for monitoring physical signs, smart jewelry and the like.

Take the terminal device as a mobile phone as an example. Fig. 10 is a block diagram illustrating a partial structure of a mobile phone according to an embodiment of the present application. Referring to fig. 10, the cellular phone includes: radio Frequency (RF) circuit 410, memory 420, input unit 430, display unit 440, sensor 450, audio circuit 460, wireless fidelity (WiFi) module 470, processor 480, and power supply 490. Those skilled in the art will appreciate that the handset configuration shown in fig. 10 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.

The following describes each component of the mobile phone in detail with reference to fig. 10:

the RF circuit 410 may be used for receiving and transmitting signals during information transmission and reception or during a call, and in particular, receives downlink information of a base station and then processes the received downlink information to the processor 480; in addition, the data for designing uplink is transmitted to the base station. Typically, the RF circuitry includes, but is not limited to, an antenna, at least one Amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), a duplexer, and the like. In addition, the RF circuitry 110 may also communicate with networks and other devices via wireless communications. The wireless communication may use any communication standard or protocol, including but not limited to Global System for Mobile communication (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE)), e-mail, Short Messaging Service (SMS), and the like.

The memory 420 may be used to store software programs and modules, and the processor 480 executes various functional applications and data processing of the mobile phone by operating the software programs and modules stored in the memory 420. The memory 420 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the cellular phone, and the like. Further, the memory 420 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

The input unit 430 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the cellular phone 400. Specifically, the input unit 430 may include a touch panel 431 and other input devices 432. The touch panel 431, also called a touch screen, may collect touch operations of a user on or near the touch panel 431 (e.g., operations of the user on or near the touch panel 431 using any suitable object or accessory such as a finger or a stylus) and drive the corresponding connection device according to a preset program. Alternatively, the touch panel 431 may include two parts of a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 480, and receives and executes commands sent from the processor 480. In addition, the touch panel 431 may be implemented in various types, such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. The input unit 430 may include other input devices 432 in addition to the touch panel 431. In particular, other input devices 432 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.

The display unit 440 may be used to display information input by the user or information provided to the user and various menus of the cellular phone. The Display unit 440 may include a Display panel 441, and optionally, the Display panel 441 may be configured in the form of a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED), or the like. Further, the touch panel 431 may cover the display panel 441, and when the touch panel 431 detects a touch operation on or near the touch panel 431, the touch panel is transmitted to the processor 480 to determine the type of the touch event, and then the processor 480 provides a corresponding visual output on the display panel 441 according to the type of the touch event. Although the touch panel 431 and the display panel 441 are shown in fig. 10 as two separate components to implement the input and output functions of the mobile phone, in some embodiments, the touch panel 431 and the display panel 441 may be integrated to implement the input and output functions of the mobile phone.

The cell phone 400 can also include at least one sensor 450, such as a light sensor, motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor that adjusts the brightness of the display panel 441 according to the brightness of ambient light, and a proximity sensor that turns off the display panel 441 and/or the backlight when the mobile phone is moved to the ear. As one of the motion sensors, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally, three axes), can detect the magnitude and direction of gravity when stationary, and can be used for applications of recognizing the posture of a mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer and tapping), and the like; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which can be configured on the mobile phone, further description is omitted here.

Audio circuit 460, speaker 461, microphone 462 may provide an audio interface between the user and the cell phone. The audio circuit 460 may transmit the electrical signal converted from the received audio data to the speaker 461, and convert the electrical signal into a sound signal for output by the speaker 461; on the other hand, the microphone 462 converts the collected sound signal into an electrical signal, which is received by the audio circuit 460 and converted into audio data, which is then processed by the audio data output processor 480 and then transmitted to, for example, another cellular phone via the RF circuit 410, or output to the memory 420 for further processing.

WiFi belongs to short-distance wireless transmission technology, and the mobile phone can help a user to receive and send e-mails, browse webpages, access streaming media and the like through the WiFi module 470, and provides wireless broadband Internet access for the user. Although fig. 10 shows the WiFi module 470, it is understood that it does not belong to the essential constitution of the handset 400, and may be omitted entirely as needed within the scope not changing the essence of the invention.

The processor 480 is a control center of the mobile phone, connects various parts of the entire mobile phone by using various interfaces and lines, and performs various functions of the mobile phone and processes data by operating or executing software programs and/or modules stored in the memory 420 and calling data stored in the memory 420, thereby integrally monitoring the mobile phone. Optionally, processor 480 may include one or more processing units; preferably, the processor 480 may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications.
