Description

Technical Field

[0001] The present invention belongs to the technical field of UWB terminals, and in particular relates to a communication and positioning integrated terminal based on UWB wireless technology. Background Art

[0002] UWB (Ultra Wideband) is a wireless carrier communication technology that uses nanosecond non-sinusoidal narrow pulses to transmit data. By transmitting extremely low-power signals over a wide spectrum, UWB can achieve data transmission rates of hundreds of Mbit / s to several Gbit / s within a range of about 10 meters. The UWB transmission power is very small, and communication equipment can achieve communication with a transmission power of less than 1mW. Low transmission power greatly extends the system power supply working time. UWB has strong anti-interference performance. UWB uses time-hopping spread spectrum signals. The system has a large processing gain. When transmitting, the weak radio pulse signal is dispersed in a wide frequency band, and the output power is even lower than the noise generated by ordinary equipment. When receiving, the signal energy is restored, and the spread spectrum gain is generated during the despreading process. UWB has an extremely wide bandwidth. The bandwidth used by UWB is above 1GHz, up to several GHz. The ultra-wideband system has a large capacity and can work simultaneously with the narrowband communication system without interfering with each other.

[0003] The existing UWB terminal system is based on UWB technology and adopts Time Difference of Arrival and TOF (Time of flight) signal flight time algorithm. It has the advantages of insensitivity to channel fading, low interception capability, low system complexity, and high positioning accuracy (30cm). The ranging algorithm based on TOF (Time of flight) signal flight time estimates the distance by measuring the flight time of the round-trip signal between two asynchronous transceivers, which belongs to the two-way ranging technology. The basic TOF algorithm signal round-trip process is as shown in the attached manual. Figure 1 As shown in the figure: Node A sends a ranging signal and records the time of sending the signal, Node B receives the signal and records the time of receiving the signal, Node B sends a response signal after processing the received signal and records the sending time, Node A records the time of receiving the response signal. In this way, the distance between nodes can be calculated according to the formula. With the time, the distance between nodes can be calculated according to the signal propagation speed.

[0004] UWB positioning technology is generally suitable for indoor unobstructed environments. Among them, TOF positioning technology is often used for one-dimensional positioning in coal mines. In long and straight tunnels, the main influencing objects are smoke media such as dust and water droplets. In this scenario, the extremely strong penetration ability of UWB positioning technology can be said to be tailor-made. The popular UWB positioning terminals on the market generally only have positioning functions. The general design is a built-in rechargeable battery and UWB positioning module. Through the connection with the positioning base station and the construction of the positioning system, the real-time acquisition function of the personnel location is finally realized. Generally, it also has positioning-related functions such as rescue and evacuation. This type of terminal has the following problems:

[0005] 1. Single function, relying on UWB positioning technology but only has positioning function;

[0006] 2. With the application and expansion of UWB positioning scenarios, the service carrying capacity of the original UWB terminal has reached a bottleneck;

[0007] 3. The warning and alarm information that needs to be prompted is becoming more and more complex. It is difficult to distinguish them by using the current sound, light, and vibration methods, and it is not convenient to remember them in actual use;

[0008] 4. Unable to upload specific distress information, only send distress signals;

[0009] 5. The current status of the positioning card (time, power, working mode, etc.) cannot be accurately displayed;

[0010] 6. Unable to know the exact location of oneself;

[0011] 7. It is impossible to communicate with the upper layer through the UWB terminal, and additional communication devices such as mobile phones are required.

[0012] Therefore, the present invention provides a terminal integrating communication and positioning based on UWB wireless technology to solve some of the technical problems raised by the above-mentioned background technology. Summary of the invention

[0024] It is further defined that the communication steps between the UWB base station and the upper-level server are as follows: after the UWB base station obtains the location information of the terminal, it transmits it to the upper-level server positioning system through the ring network to convert the positioning distance, and then the upper-level server positioning system transmits the information to the terminal through the UWB base station.

[0025] It is further defined that after the display screen module of the terminal obtains the information, an indicator light flashes, vibrates or buzzes to prompt an alarm.

[0061] The positioning module is provided with a positioning PCBA, on which a power module circuit and a UWB circuit are provided. The positioning module is used for receiving and sending positioning data and for power supply management of the entire terminal;

[0062] The screen control module is provided with a chip for information exchange with the positioning module and presenting the information on the display screen;

[0063] Specifically, the chip set in the screen control module is the MK8000 chip, which is used to interact with the positioning module, and combined with four physical buttons, it manages the screen content, ultimately realizing screen display and human-computer interaction based on UWB positioning technology.

[0064] The display screen module is electrically connected to the screen control module and the positioning module. The display screen module is used to present information intuitively. The information displayed by the display screen module includes positioning, rescue, evacuation, alarm and warning information;

[0065] The battery is electrically connected to the screen control module and the positioning module, and is used to provide power to the positioning module, the screen control module and the display screen module.

[0066] In the actual application of this embodiment, the positioning module is provided with an antenna, a positioning indicator light and a function indicator light.

[0067] In the practical application of this embodiment, the display screen module adopts an LCD display screen. With such a structural design, the LCD display screen has the advantages of low power consumption and environmental protection, and is suitable for underground use in coal mines.

[0068] In the actual application of this embodiment, the screen control module is provided with a plurality of physical buttons for managing the screen content.

[0069] In the actual application of this embodiment, a UWB base station and an upper server are also included. The terminal wirelessly communicates with the UWB base station through the built-in antenna of the positioning module, and the UWB base station is communicatively connected with the upper server.

[0070] In the actual application of this embodiment, the communication steps between the UWB base station and the upper server are as follows: after the UWB base station obtains the location information of the terminal, it transmits it to the upper server positioning system through the ring network to convert the positioning distance, and then the upper server positioning system transmits the information to the terminal through the UWB base station.

[0071] In the actual application of this embodiment, after the display screen module of the terminal obtains the information, an indicator light flashes, vibrates or buzzes to give an alarm.

[0072] In the actual application of this embodiment, the terminal includes an identification card with a screen and a mining lamp with a screen, which are respectively assembled from a control panel, a positioning panel, a battery, a display screen, a buzzer, an LED indicator light, a microphone and a battery slot housing, and include the functions of positioning, excitation, distress alarm, voice distress, voice intercom, display of alarm information and confirmation of evacuation.

[0073] Specifically, the mining lamp with a screen is provided with a lamp holder assembly to realize a lighting function.

[0074] In addition to the basic functions of positioning, calling for help, and evacuating based on UWB positioning technology, the terminal of this embodiment can also support the display of various alarms and warnings, support the query and display of its own location, support the prompt of the incentive status, support the query of the embedded version, support the query and display of various information such as time and power, etc. The product function architecture diagram is shown in the attached figure. Figure 2 As shown;

[0075] As attached Figure 3 As shown in the button description, the buttons include "return to the previous page", "flip to the next page", "confirm, ok" and "record" buttons;

[0076] As attached Figure 4 The first interface is shown as the main interface. When the battery power is less than or equal to 25%, an exclamation mark is displayed to indicate "low battery status". When there is a WIFI and UWB signal, it is full, and when there is no signal, it is displayed as a "red slash". Press any button to access the message screen. The screen sleep time is 20 seconds. During charging, the charging logo is displayed in a loop, and when fully charged, it is displayed as full.

[0077] As attached Figure 5 The second interface is the SMS interface. Click the OK button to enter the SMS content. The default display shows the most recent email. Click the "Back" button on the display to return to the SMS main interface. Click the "Next" button to display the next SMS content. The "1" in "1 / 8" in the figure indicates the number of the SMS currently being read, and "8" is the total number of SMS.

[0078] As attached Figure 6 The third interface is the location query interface. The query takes about 5 seconds and "querying" is displayed at the same time. Click the OK key to start the location query information. The displayed content is the content sent by the upper layer. Then click the "return" and "ok" keys to return to the location query interface.

[0079] As attached Figure 7The fourth interface is the version information query interface, which displays the versions of the display control software and positioning software respectively; click "Next Page" to return to the first page interface;

[0080] As attached Figure 8 The following figure shows the recording operation interface. Press and hold the "PPT" button for 2 seconds to trigger recording. The display shows "Recording" and "Recording duration / limited duration".

[0081] As attached Fig. 9 The following is the recording timeout interface. When the recording time is too long, a pop-up window "Recording time is full" will be displayed. Clicking "Return" means "Cancel", and clicking "OK" means Send.

[0082] As attached Fig.10 As shown, this interface is the SMS sending interface. Fig.11 This is the no signal prompt interface. When sending a text message, the signal condition will be detected. If there is no signal, it will prompt that there is no signal at present.

[0083] As attached Fig.12 As shown, this interface is the SMS sending completion interface. If the display shows "Completed", it means the SMS has been sent. Wait for 2 seconds or click the "OK" or "Back" button to return to the previous interface.

[0084] As attached Fig.13 As shown in the figure, this interface is the upper-layer content sending interface. When a message is received, a pop-up window will pop up for display. Then press the "Confirm" / "Back" key to read it. After the pop-up window is closed, it returns to the original interface. When a text message is received, there will be a text message prompt: "Dingding sound + vibration" for a total of 5 seconds, once per second. At the same time, the display screen will show a pop-up window (there is a new text message), and the screen will be turned off after 10 seconds.

[0085] As attached Fig.14 As shown in the figure, this is the alarm information interface. When the information is received, a pop-up window will pop up for display. Then press the "Confirm" / "Return" key to manually close it. After the pop-up window is closed, it returns to the original interface. If the evacuation information needs to be confirmed, click the confirmation key to send the "Confirmed" mark to the upper layer;

[0086] Specifically, since the alarm information sent by the upper layer is diverse, here, the type prefabrication method is adopted. The lower layer and the upper layer align the code and the corresponding alarm content. When the terminal receives the code sent by the upper layer, it plays the corresponding content according to the code. The preset alarm type is as follows Fig.15 As shown;

[0087] The advantages of this method are:

[0088] 1. Less data transmission can effectively avoid and reduce the impact of information distortion caused by packet loss due to environmental factors during data transmission.

[0089] 2. Avoid excessive data transmission that may cause the loss of positioning data or blockage of the positioning data transmission channel.

[0090] 3. Avoid the problem of excessive data volume caused by uploading and downloading multiple cards at the same time.

[0091] As attached Fig.16 As shown, this is the interface for asking for help. After pressing the OK button for 5 seconds, the display shows "asking for help", vibrates 8 times in 4 seconds, and the pop-up window automatically closes 2 seconds after the vibration ends. After the pop-up window is closed, the user returns to the original interface.

[0092] As attached Fig.17 As shown, this interface is the incentive interface. During the incentive process, a pop-up window will pop up to remind you. After 2 seconds after the incentive ends, the pop-up window will close and return to the original interface.

[0093] As attached Fig.18 As shown, this interface is a voice call interface. Press and hold the "PPT" button for 2 seconds to trigger the display of "Send call request". At this time, press the "Back" key to cancel, and press the "OK" key to confirm and send the call request;

[0094] As attached Fig.19 As shown, this interface is the call request interface. Press "Confirm" to send the call request and display "Requesting call". Press "Cancel" to cancel the call.

[0095] As attached Fig. 20 As shown, this interface is the communication failure interface. Press "Redial" to resend the call request and it will display "Requesting call". Press "Cancel" to cancel the call.

[0096] As attached Fig.21 As shown, this interface is the call interface. A normal call will display "Calling". Press "Return" to hang up the call and return to the original interface.

[0097] In summary, terminals based on UWB positioning technology can achieve the following advantages / functions:

[0098] 1. Know your current precise location

[0099] Through UWB positioning technology, the screen terminal clicks the "location query" button to send location query information to the upper layer, thereby obtaining its own location and displaying it on the interface.

[0100] 2. Accurately display a variety of alarm information

[0101] As more and more alarm information requires prompts, terminals with screens can clearly display more alarm information and accurately display the alarm content, without the need to manually identify the alarm type through memory; compared with the existing technology that can only provide sound, light, and vibration alarms, the identification card with screen display can display more content.

[0102] 3. Added UWB SMS function

[0103] The UWB SMS function is realized based on UWB positioning technology, realizing the uploading and sending of text messages.

[0104] 4. Added PTT button with UWB recording and sending functions

[0105] Based on UWB positioning technology, the UWB recording function is realized, which enables instant communication with the upper layer, getting rid of the previous dilemma of only being able to simply indicate the current status. For example, the emergency function used to only be able to press the emergency button to upload the emergency information to the upper layer, but now it can record and send the emergency request, and clearly state the current status, the assistance needed and other information.

[0106] 5. Accurately display more content

[0107] The addition of a display screen can intuitively and clearly display the current power level, time, signal strength, person's name, card number, text message content, alarm content, incentive status and other information of the identification card.

[0108] 6. Stronger business carrying capacity

[0109] The addition of the display screen enables it to carry multiple services and is perfectly suitable for a variety of positioning scenarios, including large equipment collision prevention scenarios, where relevant alarm information can be clearly displayed.

[0110] 7. Increased potential of UWB terminals

[0111] The addition of display screens gives screen terminals great potential. On the basis of existing functions, more information presentation based on UWB technology can be done behind the display screen.

[0112] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention.
