Description

Technical Field

[0001] This utility model relates to the field of communication and navigation technology, specifically to a Beidou-3 short message data transmission terminal and a terminal testing system. Background Technology

[0002] As my country's independently constructed and operated global satellite navigation system, the BeiDou Navigation Satellite System provides services far beyond positioning, navigation, and timing. Among its features, short message communication is unique to it and distinguishes it from other global navigation systems. The core equipment supporting this function is the "BeiDou short message terminal." Currently, with the completion of the BeiDou-3 global satellite navigation system network, all terminals have been upgraded to BeiDou-3 short message data transmission terminals. The core advantages of the BeiDou-3 short message terminal lie in its wide application coverage and high reliability. It is widely used in numerous fields such as emergency rescue, deep-sea fishing, geological exploration, border patrol, power transmission, and transportation, becoming a crucial means of communication support.

[0003] Currently, there are some BeiDou-3 short message data transmission terminals on the market. However, most of these terminals are single-function, typically only equipped with an RDSS communication module for sending and receiving short messages. When users need to obtain high-precision location information, they must carry an additional independent GNSS (Global Navigation Satellite System) positioning device (such as a professional GPS / BeiDou positioning instrument). This "communication terminal + independent positioning device" not only increases the user's equipment carrying burden and cost, but also requires manual operation or additional connecting cables for data interaction between the two devices, which is cumbersome, has poor real-time performance, and is prone to human error.

[0024] Reference Figure 1 As shown, this utility model provides a technical solution: a BeiDou-3 short message data transmission terminal, including a main control module 111, an RDSS module 112, a GNSS module 113, and a communication module 114; the input and output terminals of the RDSS module 112 are electrically connected to the first output and first input terminals of the main control module 111 respectively; the input and output terminals of the GNSS module 113 are electrically connected to the second output and second input terminals of the main control module 111 respectively; the input and output terminals of the communication module 114 are electrically connected to the third output and third input terminals of the main control module 111 respectively.

[0025] For example, the communication module 114 can be a Bluetooth module or a 5G communication module 114, etc.

[0026] In this embodiment, during operation, the GNSS module 113 continuously receives positioning signals from the BeiDou-3 satellites and sends the parsed positioning data to the main control module 111. The RDSS module 112 receives short message commands from the main control module 111 and requests the BeiDou-3 satellites to send short message data; the RDSS module 112 receives the short message data sent by the BeiDou-3 satellites and sends the short message data back to the main control module 111. Simultaneously, the main control module 111 can also send positioning data or received short message data to the mobile device 120 via the communication module 114. Through the deep integration of the RDSS module 112 and the GNSS module 113 on a single device, users do not need to carry and operate two separate devices, greatly improving convenience.

[0027] Reference Figure 1 As shown, in some embodiments, the BeiDou-3 short message data transmission terminal 110 includes a storage module 115, and the input and output terminals of the storage module 115 are electrically connected to the fourth output terminal and the fourth input terminal of the main control module 111 in a one-to-one correspondence.

[0028] For example, the storage module 115 can be a FLASH module, an EEPROM module, or an SD card, etc.

[0029] In this embodiment, the storage module 115 serves as the database of the BeiDou-3 short message data transmission terminal 110. The main control module 111 can store the historical trajectory generated by the GNSS module 113, the message records sent and received by the RDSS module 112, system configuration parameters, and application code in the storage module 115, and retrieve them when needed.

[0030] Reference Figure 1 As shown, in some embodiments, the BeiDou-3 short message data transmission terminal 110 includes a GPIO module 116, and the input and output terminals of the GPIO module 116 are electrically connected to the fifth output terminal and the fifth input terminal of the main control module 111 in a one-to-one correspondence.

[0031] In this embodiment, the GPIO module 116 provides the BeiDou-3 short message data transmission terminal 110 with more simplified digital signal interfaces. The main control module 111 can programmatically control the high and low levels of relevant pins of the GPIO module 116 to output signals to external devices, or detect signals from external devices to input signals to the main control module 111. External devices could be indicator lights, for example. For instance, if the terminal does not receive short message data through the RDSS module 112 within a certain period, the main control module 111 can output a high level via GPIO to activate the indicator light.

[0032] Reference Figure 1As shown, in some embodiments, the BeiDou-3 short message data transmission terminal 110 includes a download and debugging interface 117, and the input and output terminals of the download and debugging interface 117 are electrically connected to the sixth output terminal and the sixth input terminal of the main control module 111 in a one-to-one correspondence.

[0033] In this embodiment, the download and debugging interface 117 provides developers and maintenance personnel with a channel for direct communication with the kernel of the main control module 111, used for program burning, firmware upgrades, online debugging, and system log output. This simplifies the product development, testing, and maintenance process. It also supports online software updates for the BeiDou-3 short message data transmission terminal 110, facilitating vulnerability fixing and function upgrades.

[0034] Reference Figure 1 As shown, in some embodiments, the BeiDou-3 short message data transmission terminal 110 includes a battery 118, the power supply end of which is used to supply power to each module.

[0035] In this embodiment, the battery 118 serves as the built-in power source of the BeiDou-3 short message data transmission terminal 110, providing power to each module and ensuring that the BeiDou-3 short message data transmission terminal 110 can operate normally in an environment without external mains power, thus realizing the portability of the BeiDou-3 short message data transmission terminal 110.

[0036] Reference Figure 1 As shown, in some embodiments, the BeiDou-3 short message data transmission terminal 110 includes a charging interface 119 and a charging management module 1110. The power supply end of the charging interface 119 is electrically connected to the power receiving end of the charging management module 1110. The charging end of the charging management module 1110 is connected to the power receiving end of the battery 118. The input end and output end of the charging management module 1110 are electrically connected to the seventh output end and the seventh input end of the main control module 111, respectively.

[0037] In this embodiment, when charging battery 118, charging interface 119 is connected to an external power adapter. Charging management module 1110 is responsible for constant current / constant voltage charging, temperature monitoring, and overcharge / over-discharge / overcurrent protection throughout the entire charging process. Charging management module 1110 effectively protects battery 118, preventing damage or safety accidents caused by improper charging. Simultaneously, main control module 111 reads information such as battery level and charging current / voltage provided by charging management module 1110. Based on the battery level information, main control module 111 can report the power status to mobile device 120 via communication module 114, facilitating power management of BeiDou-3 short message data transmission terminal 110.

[0038] Reference Figure 1 As shown, in some embodiments, the input and output terminals of the charging interface 119 are electrically connected to the eighth output and eighth input terminals of the main control module 111 in a one-to-one correspondence.

[0039] In this embodiment, when charging the battery 118, it is connected to the main control module 111 through the charging interface 119, so that the main control module 111 can monitor whether the charging interface 119 is connected to the power supply.

[0041] For example, the sensor module 1111 can be a temperature and humidity sensor, an accelerometer, or a barometer.

[0042] In this embodiment, the sensor module 1111 is used to collect environmental or state physical quantities and convert them into electrical signals, which are then sent to the main control module 111. This upgrades the BeiDou-3 short message data transmission terminal 110 from a single communication and positioning device to a multi-parameter data acquisition node. For example, in material transportation monitoring, the terminal can simultaneously report location information and temperature and humidity data inside the container, thereby enriching application scenarios.

[0043] Reference Figure 1 As shown, in some embodiments, the BeiDou-3 short message data transmission terminal 110 includes a timer module 1112, the output of which is electrically connected to the tenth input of the main control module 111.

[0044] In this embodiment, the timer module 1112 can provide time to the main control module 111, enabling the main control module 111 to complete the timed task.

[0046] For example, the mobile device 120 can be a mobile phone or a computer, etc.

[0047] Taking the communication module 114 as a Bluetooth module as an example, the testing method of the terminal testing system 100 is as follows: 1. Mobile device 120 requests Bluetooth connection pairing from the Bluetooth module; 2. After the mobile device 120 and the Bluetooth module confirm successful pairing, the Bluetooth module sends a confirmation of connection to the mobile device 120. 3. The mobile device 120 receives the query command input by the user and sends the query command to the main control module 111 via the Bluetooth module; 4. The main control module 111 sends a query positioning data command to the GNSS module 113. After receiving the positioning signal from the Beidou-3 satellite, the GNSS module 113 parses the NEMA data to obtain the positioning data and feeds the positioning data back to the main control module 111. 5. The main control module 111 sends a query beam data command to the RDSS module 112. After receiving the signal from the Beidou-3 satellite, the RDSS module 112 parses the beam data and feeds the beam data back to the main control module 111. 6. The main control module 111 feeds back the positioning data and beam data to the mobile device 120 via the Bluetooth module; 7.
