Abstract
Description
Technical Field
[0001] This utility model relates to the field of terminal communication, and more specifically, to a Beidou terminal communication system based on LoRa technology. Background Technology
[0002] Currently, some workers need to work in the deep mountains for several days at a time. If there is no public network signal in the mountains, ordinary mobile phones cannot make or receive calls, and satellite phones will also be unusable due to severe satellite obstruction in the mountains.
[0003] In remote, uninhabited areas of primeval forests, the terrain is particularly complex, with extremely steep and dense forests and numerous cliffs. Due to the dense forests, even on a sunny day outside, the depths of the primeval forest may be shrouded in thick fog, incessant rain, or even complete darkness, easily causing disorientation. Once lost, it is very difficult to find the original path, and movement may be more difficult than expected, greatly increasing the likelihood of navigation and communication equipment malfunctioning. Moreover, there are dangerous factors such as streams and ravines in the mountains, and if workers are entering the mountains during days of continuous rain, the risk of geological disasters such as landslides, collapses, and mudslides, as well as environmental hazards such as hypothermia and poisoning, is extremely high.

[0018] Figure 3 This is a schematic diagram of the structure of a Beidou terminal communication system based on LoRa technology according to another embodiment of the present invention. Detailed Implementation
[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0020] Figure 1 This is a schematic diagram of the structure of a Beidou terminal communication system 001 based on LoRa technology according to an embodiment of the present invention, as shown below. Figure 1As shown, the BeiDou terminal communication system 001 includes: a BeiDou terminal module 101 and at least one LORA forwarding module 201; the BeiDou terminal module 101 includes a first LORA communication circuit 111 and a BeiDou RDSS communication circuit 112; the LORA forwarding module 201 includes a second LORA communication circuit 211, a second distress signal triggering circuit 212, and a second location reporting circuit 213; the BeiDou terminal module 101 and the LORA forwarding module 201 are connected via the first LORA communication circuit 111 and the second LORA communication circuit 211; the second distress signal triggering circuit 212 can obtain... The system acquires a distress signal and transmits it to the BeiDou terminal module 101 via the LORA communication connection between the second LORA communication circuit 211 and the first LORA communication circuit 111. The second location reporting circuit 213 can automatically parse the location information of the LORA forwarding module 201 and transmit the location information to the BeiDou terminal module 101 via the LORA communication connection between the second LORA communication circuit 211 and the first LORA communication circuit 111. The BeiDou terminal module 101 establishes a communication connection with the user terminal via the BeiDou RDSS communication circuit 112 to transmit the distress signal and location information to the user terminal.
[0021] The BeiDou RDSS communication circuit is a communication method based on the BeiDou short message service. As a key application of the BeiDou-3 system, the BeiDou-3 short message service plays a crucial role in providing emergency rescue and IoT communication. Users can send and receive text messages globally via BeiDou-3 satellites simply by entering the message content on their mobile phones or other terminal devices. Compared to traditional mobile communication methods, the BeiDou-3 short message service offers advantages such as high reliability, wide coverage, and low cost, especially in remote areas or disaster situations, ensuring the security and stability of communication.
[0022] When workers use the Beidou terminal communication system 001 in remote mountainous areas, the Beidou terminal module 101 is placed in a designated area, such as a campsite. For example, the Beidou terminal module 101 can be a GISA Z20 type Beidou terminal device. The LORA relay module 201 can be carried on the person; for example, it can be a portable LORA transponder. When workers encounter danger and need rescue, they can trigger the second distress signal triggering circuit 212 to send a distress signal. The second distress signal triggering circuit 212 will then transmit the acquired distress signal to the Beidou terminal module 101 via the LORA communication connection between the LORA transponder and the Beidou terminal module 101. Simultaneously, the second location reporting circuit 213 of the LORA transponder, in distress mode, will automatically parse the location information of the LORA transponder and send this location information to the Beidou terminal module 101 via the LORA communication connection. After receiving the distress signal and location information from the LORA transponder, the Beidou terminal module 101 will transmit the distress signal and location information to the user terminal through the Beidou RDSS communication circuit, so that remote monitoring personnel know that there are workers in danger and need rescue, which will facilitate the remote monitoring personnel to launch a rescue operation.
[0023] Furthermore, the second distress signal triggering circuit may include a distress signal acquisition sub-circuit and a distress signal transmission sub-circuit electrically connected to each other. The distress signal acquisition sub-circuit is used to acquire a distress signal and transmit the acquired distress signal to the distress signal transmission sub-circuit. The distress signal transmission sub-circuit is connected to the BeiDou terminal via LoRa communication and is used to transmit the distress signal to the BeiDou terminal module via the LoRa communication connection. For example, the distress signal acquisition sub-circuit may be an SOS button set on the LoRa transponder, and the distress signal transmission sub-circuit may be a transmission circuit built into the LoRa transponder. When the operator carrying the LoRa transponder presses the SOS button to send a distress signal and activate SOS mode, the distress signal transmission sub-circuit will send the distress information to the BeiDou terminal module via the LoRa communication connection.
[0024] Furthermore, such as Figure 2 As shown, the Beidou terminal module 101 also includes a judgment circuit 113 and a first location reporting circuit 114 that are electrically connected to each other; the judgment circuit 112 and the second location reporting circuit 212 are connected via LORA communication; the judgment circuit 112 is used to determine whether the second location reporting circuit 212 sends the location information of the LORA forwarding module 201 to the Beidou terminal module 101 via the LORA communication connection; the first location reporting circuit 114 can automatically parse the location information of the Beidou terminal module 101 and send the location information to the user terminal via the Beidou RDSS communication circuit 112.
[0025] Specifically, when the operator sends a distress signal through the LORA forwarding module 201, the judgment circuit 113 of the Beidou terminal module 101 will determine whether the second location reporting circuit 212 in the LORA forwarding module 201 has sent the location information of the LORA forwarding module 201 to the Beidou terminal module 101. If the judgment circuit 113 determines that the second location reporting circuit 212 has sent location information through the LORA communication connection, then the first location reporting circuit 114 of the Beidou terminal module 101 will not resolve its own location. If the judgment circuit 113 determines that the second location reporting circuit 213 has not sent location information through the LORA communication connection, then the first location reporting circuit 114 of the Beidou terminal module 101 will automatically resolve the location information sent by the Beidou terminal module 101, and then send the distress signal sent by the LORA forwarding module and the location information of the Beidou terminal module to the user terminal through the Beidou RDSS communication circuit 112. This allows remote monitoring personnel to know that there are workers in danger and need rescue, which facilitates remote monitoring personnel to launch rescue operations, provides a general rescue range for rescue operations, and provides multiple guarantees for the safety of workers.
[0026] Furthermore, such as Figure 2 As shown, the Beidou terminal module 101 also includes a first distress signal triggering circuit 115; the first distress signal triggering circuit 115 can acquire distress signals and send distress information to the user terminal through the Beidou RDSS communication circuit 112.
[0027] Specifically, to further ensure the safety of personnel working outdoors in remote mountainous areas, a first distress signal triggering circuit can be installed on the BeiDou terminal module, such as an SOS button. For example, if a worker carrying a LoRa repeater module fails to send relevant information for an extended period, the operator of the BeiDou terminal module can press the SOS button. This triggers the first distress signal triggering circuit to send a distress signal. Simultaneously, the first location reporting circuit automatically parses the location information of the BeiDou terminal module. At this point, the BeiDou terminal module will transmit the distress signal and location information to the user terminal via the BeiDou RDSS communication circuit. This allows remote monitoring personnel to initiate rescue operations based on the distress signal, providing a general rescue area and offering multiple layers of protection for the workers' safety.
[0028] Furthermore, such as Figure 2As shown, the LORA forwarding module 201 also includes a security reporting circuit 214; the security reporting circuit 214 can acquire a secure signal and send the secure signal to the Beidou terminal module 101 through the LORA communication connection between the second LORA communication circuit 211 and the first LORA communication circuit 111.
[0029] Specifically, to facilitate timely monitoring of personnel operating with the LoRa relay module, a second distress signal trigger circuit (e.g., an SOS button on the LoRa relay module) and a safety reporting circuit (e.g., a "report safety" button on the LoRa relay module) can be installed on the LoRa relay module. When a worker presses the "report safety" button, a safety signal is triggered and transmitted to the BeiDou terminal module via LoRa communication. This allows workers to easily report their safety status at any time, enabling the personnel operating the BeiDou terminal module to be aware of the workers' safety. Alternatively, after triggering the SOS button, if a worker finds the danger has passed, they can press the "report safety" button to inform monitoring personnel.
[0030] When the operator of the Beidou terminal module receives the "safe" signal from the "safe" button on the LORA transponder, the distress exit circuit 116 in the Beidou terminal module will send the "safe" signal to the user terminal through the Beidou RDSS communication circuit, so that the remote monitoring personnel know that the operator is safe.
[0031] Furthermore, such as Figure 2 As shown, the LORA forwarding module also includes an encoding identification circuit 215 with encoding information, which is electrically connected to the second LORA communication circuit 212. The encoding identification circuit 215 sends the encoding information to the Beidou terminal module 101 through the LORA communication connection between the second LORA communication circuit 211 and the first LORA communication circuit 111, so that the Beidou terminal module 101 can send the encoding information to the user terminal through the Beidou RDSS communication circuit.
[0032] Specifically, when the operator sends a distress signal through the LORA relay module, the encoding and identification circuit will send the unique identifiable encoding information of the LORA relay to the Beidou terminal module through the LORA communication method. The Beidou terminal module will then send the unique identifiable encoding information (e.g., ID information) to the user terminal through the Beidou RDSS communication circuit, so that the remote monitoring personnel can quickly know which relay sent the distress signal and can carry out rescue more accurately.
[0033] Furthermore, such as Figure 2As shown, the Beidou terminal module 101 also includes a timing circuit 117 that is electrically connected to both the first LORA communication circuit 111 and the Beidou RDSS communication circuit 112; the timing circuit 117 is used to periodically send the distress signal and location information received by the Beidou terminal module 101 to the user terminal through the Beidou RDSS communication circuit.
[0034] Specifically, in order to further improve the life protection of workers, a timing circuit can be set in the Beidou terminal module. When the worker is in distress mode through the LORA transponder, the Beidou terminal module can activate the timing circuit. The timing circuit will continuously send the received distress signal, location information and / or coded information to the user terminal at fixed time intervals, so that remote monitoring personnel can clearly know that the worker is in a state of needing rescue.
[0035] This utility model also provides another embodiment of the Beidou terminal communication system, such as... Figure 3 As shown, the BeiDou terminal communication system has multiple LORA forwarding modules, and the BeiDou terminal module also includes a sequential arrangement circuit. The sequential arrangement circuit is connected to the second distress signal triggering circuit and the second location reporting circuit via LORA communication, and is electrically connected to the BeiDou RDSS communication circuit. The sequential arrangement circuit is used to sort the distress signals and location information sent by the multiple LORA modules in chronological order, so that the BeiDou terminal can send the sorted distress signals and location information to the user terminal through the BeiDou RDSS communication circuit.
[0036] Furthermore, the BeiDou terminal communication system also includes: a mobile terminal device; the BeiDou terminal module further includes a first Bluetooth connection circuit, and the LoRa forwarding module further includes a second Bluetooth connection circuit; the BeiDou terminal module connects to the mobile terminal device via the first Bluetooth connection circuit; the LoRa forwarding module connects to the mobile terminal device via the second Bluetooth connection circuit.
[0037] Specifically, operators can also choose to operate the BeiDou terminal module and the LoRa forwarding module through mobile terminal devices. By integrating the above-mentioned functions into the mobile terminal module, operators can operate the BeiDou terminal module and the LoRa forwarding module through mobile terminal devices.
[0038] Figure 3 The BeiDou terminal module and LoRa forwarding module shown in the embodiment are Figure 2 The structures and functions of the BeiDou terminal module and the LORA forwarding module in the illustrated embodiments are the same, and will not be described again here.
[0039] like Figure 3As shown, when there are multiple LORA transponders, that is, the Beidou terminal module is connected to multiple LORA transponders through LORA communication. For example, if multiple workers send out distress signals and location information through LORA transponders, in order to ensure that the rescue operation can proceed in an orderly manner according to the time sequence, the sequence arrangement circuit 118 in the Beidou terminal module will sort the distress signals and location information according to the time sequence of their transmission. Then, the sorted distress signals and location information will be sent to the user terminal through the Beidou RDSS communication circuit. That is, the LORA transponder that sends out the distress signal first will be detected by the remote monitoring personnel first, and then the rescue operation will be initiated.
[0040] If a LoRa transponder is found to have exited SOS mode (e.g., pressed the "report safety" button or received rescue), the deletion sub-circuit 801 in the BeiDou terminal module will delete the corresponding SOS signal and location information of that LoRa transponder from the sorted distress signals and location information. The sequence arrangement circuit 118 will then re-sort the remaining distress signals and location information and send the sorted distress signals and location information to the user terminal through the BeiDou RDSS communication circuit. This process will continue until all LoRa transponder modules have issued a safety signal. At this point, the exit sub-circuit 802 will send an exit distress signal to the distress exit circuit 116. The distress exit circuit 116 will then send an exit distress signal through the BeiDou RDSS communication circuit, and the remote monitoring personnel will exit the distress mode.
[0041] Finally, the Beidou terminal communication system described in this application is merely a preferred embodiment and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
