Description

Technical Field

[0001] The present invention relates to the technical field of satellite signal transmission, acquisition and information processing, and in particular to an integrated satellite signal generation and acquisition comparison training system based on a modular intelligent platform designed to cope with complex scenarios. Background Art

[0002] As we all know, conventional satellite terminals currently include the 9523 and 9602 models. In most cases, these two models are used separately. However, due to the complexity of usage environments and situations, carrying both devices simultaneously is inconvenient due to their heavy weight, making it difficult for a single person to carry them for extended periods or navigate complex terrain.

[0003] Furthermore, the two existing satellite terminals lack real-time status display devices, making it difficult to quickly verify their status. Monitoring of their operating status requires connection to a remote computer. This significantly increases maintenance costs and complexity, hindering proper operation and preventing damage from misoperation.

[0004] On the other hand, the widespread adoption of remotely controlled electronic mobile platforms, such as drones and unmanned marine vehicles, has enriched numerous application scenarios beneficial to both production and daily life. Among these applications, the use of these remotely controlled unmanned mobile devices as signal and information collectors has become an increasingly prominent area of focus. In the fields of reconnaissance and search and rescue, the demand for remotely controlled unmanned mobile devices to enhance their signal collection and information processing capabilities is increasing. However, existing signal collection, processing, and comparison equipment, generally mounted on large ships or aircraft, is bulky, exhibits poor heat dissipation, and is complex and expensive to manufacture.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0034] like Figure 1 As shown, the integrated satellite signal generation, acquisition, and comparison training system described in the present invention is a system that simulates and creates communication intervention and training scenarios. The system includes multiple mobile targets equipped with integrated portable emergency communication equipment as monitored objects, and at least one device equipped with signal acquisition, processing, and comparison equipment as a communication intervener. The monitored objects are considered targets, and the communication intervener acts as a listener. This allows the system to simulate a single listener tracking multiple targets, thereby monitoring possible voice (9575 module), data (9523 module), and SMS (9602 module) communications between the targets and GPS satellites in real time.

[0035] The structures of the various components of the system in the embodiment are described in detail below.

[0036] like Figures 2 to 4 As shown, the integrated portable emergency communication device in the system of the present invention comprises a housing A100, within which are a satellite terminal A105, a handheld communication terminal device A120, and a tablet computer A130. Specifically, the handheld communication terminal device A120 and tablet computer A130 are embedded in the inner door of the housing via protective foam A140. The handheld communication terminal device A120 is a 9575 handheld communication terminal for voice communication. The tablet computer A130 is a 10.1-inch tablet computer running Windows or Unix, which communicates with the satellite terminal via Wi-Fi.

[0037] Of course, as the core of the entire device, the satellite terminal includes the main control board A110, lithium battery A150, and status display A185. The main control board A110 and lithium battery A150 are fixed inside the box by bracket A170; the status display A185 is placed on the panel A180.

[0038] The main control board (A110) is an integrated circuit board (IC). It contains electronic components and chips, including a Wi-Fi communication module (A111), a 9602 data communication terminal module (A112), a 9523 network communication terminal module (A113), and a TTL-to-Ethernet module (A114). The main control board also features a display screen interface (A115) for connecting to a status display screen (A185). A battery interface (A116a) connects to a lithium battery (A150). Furthermore, the main control board features a power interface (A116b), a switch interface (A117), a USB connector (A118), and a network port (A119), which connect to the DC12V power input connector (A181), power switch (A182), USB interface (A183), and network interface (A101) on the housing (A100).

[0039] In the specific structure of the main control board's circuit module, the GPS antennas of the 9602 data communication terminal module A112 and the 9523 network communication terminal module A113 are connected to a power divider A160 to form a single GPS antenna, which is then led out of the enclosure. The satellite antennas of the 9602 data communication terminal module A112 and the 9523 network communication terminal module A113 are connected to the satellite antenna interface A103 on the enclosure A180 and then led out of the enclosure. The 9602 data communication terminal module A112 and the 9523 network communication terminal module A113 are connected to the TTL-to-Ethernet module A114 via the RS232 interface. The TTL-to-Ethernet module A114 transmits data information for external wired communications via the network interface A101.

[0040] In addition, the case contains an accessory box A190 for storing components required for use, such as a power adapter A191 and a satellite antenna A192. This box is covered with a panel A180 that opens and closes via hinges 184. The case A100 is made of waterproof, dustproof, and shockproof material and is equipped with a network port A101, a satellite antenna port A103, and a GPS antenna A102.

[0041] In use, a tablet computer connects to the satellite terminal via Wi-Fi using interactive software based on Windows or Unix. A TTL-to-Ethernet module converts the network protocol to connect to the 9602 Data Communication Terminal Module and the 9523 Network Communication Terminal Module. The control module then connects to the satellite to send satellite messages to other terminals or a control center. The device can also transmit the GPS location of the satellite terminal through the module. Furthermore, the satellite terminal's Ethernet port can be connected to other remote control devices via a network cable for control. The 9575 handheld terminal can also be used to make voice calls without any distance restrictions.

[0042] like Figure 5 As shown, the portable sealed signal acquisition and information processing device in the system of the present invention includes an information processing device body, a receiving antenna filter component and a GPS+4G combination antenna B107.

[0043] The receiving antenna filter assembly includes an external antenna B112, a dedicated filter B113, and a radome B114, which are fixed as a whole to one side of the heat sink housing. The GPS+4G combination antenna B107 is fixed to one side of the heat sink housing with its own nuts.

[0044] The information processing device includes a heat dissipation housing B101, an upper cover B102, an inner cover B103, and an information processing module B104, a signal receiving and processing module B105, and a power supply module B106 fixed to the bottom surface of the heat dissipation housing B101 by screws.

[0045] The GPS+4G combined antenna B107 is connected to the information processing module B104 and the signal receiving processing module B105 via wires.

[0046] An RJ45 interface B108, a power switch button B109 and a DV12V power socket B110 are provided on one side of the heat dissipation housing B101.

[0047] The power module B106 provides the power required for the operation of the information processing module and the signal receiving and processing module by connecting the DV12V power socket B110 and the RJ45 interface B108. The power module B106 can provide both DV12V and POE power supply modes.

[0048] Heat pipes B111 are fixed to the bottom of the heat sink housing B101 for heat dissipation. The inner cover B103 is screwed to the upper opening of the heat sink housing B101 to ensure a seal between the internal components. The upper cover B102, with multiple vertical fins, is fixed to the inner cover B103 to ensure the device maintains a normal operating temperature.

[0049] When the device is in operation, the receiving antenna filter assembly filters and amplifies the received analog signal, then transmits it to the signal receiving and processing module B105 via a wired RF interface. The signal receiving and processing module B105 converts the amplified analog signal into a digital signal and transmits it to the information processing module B104, which is connected via a coaxial cable. The information processing module B104 decodes the digital signal and transmits the decoded information via the RJ45 interface B108 or the 4G wireless communication network connected to the GPS+4G combination antenna B107. The GPS+4G combination antenna B107, connected to the signal receiving and processing module B105, can obtain the device's location information in real time. Furthermore, it uses the 4G wireless communication network connected to the GPS+4G combination antenna to receive real-time adjustments to the device's operating parameters (such as the received signal frequency band and information processing accuracy) from a remote control terminal (computer or server).

[0050] like Figure 6 As shown, the signal receiving and processing module includes a module cover B201, a bias switch B202, a signal processing board B203, a shielding cover B204, a timing board B205, and a module base B206. One end of the bias switch B202 is connected to the receiving antenna filter assembly, and the other end is wired to the signal processing board B203. The signal processing board B203 is covered with a shielding cover B204 and wired to the timing board B205. The timing board B205 is also connected to the GPS+4G combination antenna. The bias switch B202, signal processing board B203, and shielding cover B204 are housed within the module cover. The timing board B205 is secured to the module base B206. The module cover B201 and module base B206 are screwed together to form the signal receiving and processing module.

[0051] like Figure 7 As shown, the receiving antenna filter assembly includes an external antenna B301, a dedicated filter B302, and a radome B303. The external antenna B301 is connected to the dedicated filter B302 via an SMA connector B304. The radome is then attached to the outside of the heat sink housing and secured with screws. An annular recess is located along the base of the radome, and a sealing ring B305 is installed to enhance the waterproofing of the receiving antenna filter assembly.

[0052] like Figure 8 As shown, a plurality of vertically arranged heat sink structures are provided on the bottom surface B401 of the heat dissipation housing, and an air duct cover B402 is fixed to the outside of the bottom surface by screws. A heat dissipation fan B403 is arranged between the bottom surface B401 and the air duct cover B402. By driving the fan, a heat dissipation and cooling air duct is formed between the heat dissipation housing and the air duct cover.

[0053] It's important to note that during simulations, the target and monitor systems comprised of the aforementioned equipment typically maintain a fixed, unobstructed range of 30 kilometers from the targets to ensure high accuracy of monitored information. The targets simulate the movements of objects (including vehicles, aircraft, and marine vessels) that pose a threat to national security, whether at land borders, at sea, or in the air. Once the entire simulation training system is in place, the monitors compare and analyze the restored monitored information with the information transmitted by the simulated targets to verify and improve their technical capabilities. This will accumulate technical experience for intelligence collection and control in real-world border and sovereignty areas, enhancing operational capabilities for information collection and response operations. Ultimately, achieving the efficient goal of maintaining troops for a thousand days while deploying them for a single moment.

[0054] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention.
