Description

Technical Field

[0001] The invention relates to the field of life-saving equipment, in particular to a display and control system of a portable life-saving radio station and a use method thereof. Background Art

[0002] A life-saving radio is an emergency communication device that can be used in areas far from human habitation, such as the sea, mountains, and deserts, to communicate with the outside world and send distress signals so as to get rescued as soon as possible. It is easy to operate, easy to carry, and has a wide communication range. It is one of the essential equipment for seafarers, mountaineering enthusiasts, explorers and other outdoor activities. The functions of a life-saving radio include distress alarm function: when the user is in a dangerous situation, such as a ship in distress or a plane crash, the user can send a distress signal to the outside world through the life-saving radio to inform the outside world of his or her distress and seek help from rescue forces. For example, when the China Ship Research and Design Center selects manufacturers of portable life-saving radio equipment, it requires that the equipment can complete the long-distance distress alarm task to the shore when the ship is in distress. Position indication function: It can let the rescue party know the approximate location of the user, which helps the rescue force quickly locate the personnel or equipment that needs rescue. Short message communication function: It can send short text messages to convey necessary information, such as its own status, surrounding environment, etc. The portable life-saving radio purchased by the China Ship Research and Design Center is required to have short message communication function so as to exchange necessary information with the shore in case of distress. However, the display and control system of the existing life-saving radio is cumbersome in operation and display, and cannot timely and specifically send out the distress situation. It also uses bare-metal programming, which has low execution efficiency, inconvenient operation, and is affected by timeliness.

[0003] For example, the Chinese patent with the publication number CN101408610A discloses a Beidou-based spread spectrum radio life-saving device and a life-saving signal processing method. The distress part is composed of an encoder, a spread spectrum module and a modulation and transmission module. The location signal of the rescued party is processed by the Beidou receiver and enters the encoder to be converted into a navigation message of the spread spectrum radio together with the time information content. The spread spectrum module is used to spread the spectrum, and the generated signal is sent through the antenna through the modulation and transmission module; the rescue part is composed of a radio frequency front end, a signal processing platform and an output display part. The radio frequency front end extracts useful signals by amplifying and filtering the received signals and sends them to the signal processing platform. The signal processing platform despreads and demodulates the input signals to obtain the location information of the rescued person and transmits it to the output display module for output. When sending a distress signal, the above-mentioned Beidou-based spread spectrum radio life-saving device and life-saving signal processing method use the display control system constructed by bare metal programming to send out distress signals, which has low execution efficiency, inconvenient operation, and is affected by time.

[0004] In view of this, it is necessary to provide a display and control system of a portable life-saving radio and a method of using the same. Summary of the invention

[0005] The present invention provides a display and control system of a portable life-saving radio and a method of using the same, which effectively solves the problems of low execution efficiency, inconvenient operation and easy time-related influence of the display and control system of the existing life-saving radio.

[0006] The technical solution adopted by the present invention is:

[0007] The display and control system of the portable life-saving radio station comprises a main menu module, a communication function module, a query function module, a setting function module and a detection function module. The main menu module interacts with the communication function module, the query function module, the setting function module and the detection function module.

[0008] Furthermore, the communication function module includes recipient address selection, pre-stored message selection, new Chinese character message, new code message and new mixed message.

[0009] Furthermore, the query function module includes a positioning information query function, a software version information query function, and a message sending and receiving query function.

[0010] Furthermore, the message sending and receiving query function includes message information query and message object query.

[0013] Furthermore, the detection function module also includes a communication function module self-check, a query function module self-check and a setting function module self-check.

[0014] Furthermore, the main menu module is displayed through an OLED display screen, which includes the OLED display screen being connected to buttons through a display control chip.

[0015] The life-saving method of the portable life-saving radio station adopts the portable life-saving radio station, and comprises the following steps:

[0016] S1. Start the main menu module so that the operation interface of the main menu module displays a communication function module, a query function module, a setting function module, and a detection function module;

[0017] S2. When it is necessary to send out an alarm message, select the distress status, distress time and distress coordinates through the setting function module, and then select the communication function module to send out an alarm message; when it is necessary to query the indicator information of the life-saving radio station, select the query function module; when it is necessary to check whether the function of the life-saving radio station is used normally, select the detection function module.

[0018] Furthermore, the life-saving method of the portable life-saving radio station adopts the portable life-saving radio station and also includes S3, closing the main menu module.

[0019] Beneficial effects of the invention:

[0020] 1. The event callback mechanism of LVGL is used to manage hardware and human-computer interaction, which improves the execution efficiency of display control, makes operation more convenient and less susceptible to timeliness, and ensures the accuracy and efficiency of message transmission.

By setting up the function module to display the coordinate information of the path points recorded by the life-saving radio, it can be ensured that in the case of distress and real-time positioning is impossible, the coordinate information of the recorded path points can be used as the coordinate information of the alarm, effectively increasing the probability of rescue of people in distress.

[0022] 3. The query function module can be used to query previous message information to ensure that detection is performed after the message is sent to further confirm the message sending and receiving status.

[0023] 4. Through the detection function module, each module of the display and control system of the entire life-saving radio can be tested to ensure the normal operation of the entire life-saving radio and the normal sending and receiving of satellite communication information.

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 As shown, the first embodiment provided by the embodiments of the present application is a display and control system of a portable life-saving radio, including a main menu module 1, a communication function module 2, a query function module 3, a setting function module 4, and a detection function module 5. The main menu module 1 interacts with the communication function module 2, the query function module 3, the setting function module 4 and the detection function module 5.

[0028] In actual use, when encountering danger, operate the main menu module 1, so that the main interface of the main menu module 1 displays four options: communication function module 2, query function module 3, setting function module 4, and detection function module 5. Select the query function module 3 to query the location information and other danger conditions when in danger, select the setting function module 4, and select the danger information encountered; select the communication function module 2 to send the danger information encountered to the recipient. When the communication function module 2 has a fault, the communication function module 2 is detected by the detection function module 5.

[0029] In the above design, it is possible to realize the rapid selection of dangerous situations and timely detect the functions of the entire portable life-saving radio station, thereby ensuring that the life-saving radio station is not affected by time and improving execution efficiency.

[0030] Specifically: Figure 1 As shown, the communication function module 2 includes a recipient address selection 21, a pre-stored message selection 22, a new Chinese character message 23, a new code message 24 and a new mixed message 25.

[0031] In actual use, you can manually enter the recipient's communication address, or you can choose the default recipient address. By selecting the pre-stored message 22, possible danger messages can be stored in advance. By creating a new Chinese message 23, you can manually enter Chinese message information, which means that the entire message is carried by Chinese characters, such as Ocean No. 2. By creating a new code message 24, it means that the entire message is carried by codes, such as 10001. Create a new mixed message 25, which means that the carrier of the entire message includes both Chinese characters and codes, such as Ocean No. 10001.

[0032] In the above design, the multiple options of the communication function module 2 enable the person in distress to send the message information in the form of multiple carriers, making the message information more accurate.

[0033] Specifically: Figure 1 As shown, the query function module 3 includes a positioning information query function 31 , a software version information query function 32 , and a message sending and receiving query function 33 .

[0034] In actual use, the longitude and latitude of the distress location can be found in time through the positioning information query function 31. The version information of the portable life-saving radio can be found through the software version information query function. The message sent in the past can be found through the receiving party message information query, including the message content, the message receiver information, the message sending time and whether the message was sent successfully.

[0035] In the above design, the design and specific implementation method of the query function module 3 facilitate the rapid positioning of the distress area, and can also quickly find out the content, sending status and other information of the messages sent in the past, so that the rescue personnel can check the messages and evaluate their own situation.

[0036] Specifically: Figure 1 As shown, the message sending and receiving query function 33 includes message information query and message object query.

[0037] In actual use, you can query the message information to understand the content of the message sent, and query the message object to understand the object information of the received message.

[0038] In the above design, a more comprehensive query of the message can be achieved through message information query and message object query.

[0039] Specifically: Figure 1 As shown, the setting function module 4 includes system time setting 41, location information setting 42, distress nature setting 43 and factory reset 44.

[0040] In actual use, when the satellite time of the lifesaving radio is wrong through the system time, the satellite time on other devices can be matched and then manually input through the system time setting 41. When the lifesaving radio cannot locate its own longitude and latitude position information through the location information setting 42, the nearest longitude and latitude in multiple location information of the path recorded by the lifesaving radio by default is found, and this longitude and latitude is used as the location information for alarm and help. The nature of the distress includes multiple default distress states, such as explosion, flooding, stranding, sinking, abandonment, unspecified nature of distress and other information, and the option corresponding to the distress state is selected. By restoring the factory settings 44, the factory settings 44 of the entire lifesaving radio are restored.

[0041] In the above design, the design and specific implementation of the functional module 4 can effectively send the time and location information of the dangerous situation to the search and rescue party as accurately as possible.

[0042] Specifically: Figure 1As shown, the detection function module 5 includes Beidou self-loop detection 51, IC detection 52, satellite communication power test 53, and satellite communication bit error rate test 54. It should be noted that the bit error rate is a unit of measurement for measuring transmission errors in digital communication systems, which indicates the ratio between the number of bits misunderstood or erroneously received by the receiving end and the number of bits sent during data transmission. This ratio is usually expressed as a percentage or an exponent. The bit error rate is caused by a variety of factors, including noise, interference, fading, clock deviation, and imperfections in the transmission channel. A lower bit error rate means that the data transmission is more accurate, and the receiving end correctly parses and receives the sent bit stream. For digital communication systems, the goal is to reduce the bit error rate as much as possible to achieve high-quality and reliable data transmission.

[0043] In actual use, Beidou self-loop detection 51 simulates the real satellite signal environment to detect the positioning, navigation and communication functions of the application terminal to ensure its stability and accuracy in actual use. The performance indicators cover the basic functions of the application terminal, such as short message communication, positioning, precision timing, etc.; the performance indicators include bit error rate, sensitivity, number of receiving channels, etc. By selecting IC detection 52, it is tested whether the integrated circuit of the life-saving radio can realize its designed function, such as analog circuit function test. By selecting the satellite communication power test 53, the distance, quality and efficiency of communication are tested. By selecting the satellite communication bit error rate, the bit error rate of the receiving satellite signal of the entire life-saving radio is tested and verified.

[0044] In the above design, the design and specific implementation method of the detection function module 5 can detect the operating status of the satellite communication of the entire life-saving radio station, ensuring the normal transmission of the Beidou signal and the accuracy of the transmission.

[0045] Specifically: the detection function module 5 also includes a communication function module self-check, a query function module self-check and a setting function module self-check.

[0046] In actual use, the communication function of the communication function module 2 is tested through the self-test of the communication function module 2, the query function of the query function module 3 is tested through the self-test of the query function module 3, and the setting function of the setting function is tested through the self-test of the setting function module 4.

[0047] In the above design, the design and specific implementation method of the detection function module 5 can realize self-detection of each module and improve the comprehensiveness of the detection.

[0048] Specifically: the main menu module 1 is displayed through an OLED display screen, which includes the OLED display screen being connected to buttons through a display control chip. For example, the display control chip communicates with the main control chip through a custom serial port protocol to control hardware such as 9GHz, satellite communication, VHF / aviation, and flash. The display control GD32F450 chip is connected to a 2.58-inch OLED display screen with an RGB565 interface and registered as a display device under the LVGL framework. The 24-key keyboard is registered as a Button device under the LVGL framework; with the callback function written in advance, real-time interaction between buttons, screens, and hardware is achieved. The display control GD32F450 has an external 32M Byte SDRAM as the display buffer of LVGL; at the same time, an external SPI interface Flash is connected, and a fatfs file system is loaded for storing messages and positioning information.

[0049] During actual use, command information is input through buttons, and the input command information is displayed through the OLED display screen.

[0050] In the above design, the structural design and specific implementation method of the main menu module 1 facilitate the input and display of instructions.

[0051] The second embodiment provided by the present application is a method for using a display and control system of a portable life-saving radio station, using the display and control system of the portable life-saving radio station, comprising the following steps:

[0052] S1, start the main menu module 1, so that the operation interface of the main menu module 1 displays the communication function module 2, the query function module 3, the setting function module 4, and the detection function module 5;

[0053] S2. When it is necessary to send out an alarm message, select the distress status, distress time and distress coordinates through the setting function module 4, and then select the communication function module 2 to send out an alarm message; when it is necessary to query the indicator information of the life-saving radio station, select the query function module 3; when it is necessary to check whether the function of the life-saving radio station is used normally, select the detection function module 5.

[0054] In the above design, the life-saving method using a portable life-saving radio can achieve accurate transmission of the dangerous situation encountered, which is suitable for the new generation Beidou system and effectively increases the success rate of search and rescue.

[0055] The method for using the display and control system of the portable life-saving radio station also includes S3, closing the main menu module 1.

[0056] In the above design, after sending a distress message, energy saving protection of the lifesaving radio station is achieved by closing the main menu module 1.

[0057] To further explain in detail, it should be understood that the above is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
