Description

Technical Field

[0001] This utility model relates to the field of portable electronic device technology, specifically to a portable ruggedized computer. Background Technology

[0002] In scenarios such as field exploration and emergency rescue, personnel often need to rely on multiple devices simultaneously to complete communication and positioning tasks: for example, using walkie-talkies for short-range group communication (such as team collaboration), communicating with the command center via 4G, and obtaining high-precision location information using BeiDou satellite positioning terminals (especially in areas without mobile network coverage). However, traditional solutions have the following drawbacks:

[0003] Equipment is scattered: walkie-talkies, mobile phones, and positioning terminals need to be carried separately, which increases the weight and makes operation cumbersome.

[0004] Functional fragmentation: Each device operates independently, making data sharing impossible (e.g., location information cannot be directly shared to the communication interface), which affects emergency response efficiency.

[0005] Power supply dependence: The simultaneous use of multiple devices leads to rapid power consumption and insufficient continuous operation capability in the field.

[0006] While some existing mobile phones integrate walkie-talkie or location functions, their performance is limited by consumer-grade hardware, making it difficult to meet the demands of professional scenarios such as big data processing (e.g., map rendering, concurrent multi-channel communication), rugged protection, interface expansion, and long battery life. Therefore, developing a highly integrated, ruggedized portable computer that supports multimodal communication and location has significant application value. Utility Model Content

[0007] The purpose of this invention is to address the above-mentioned shortcomings by proposing a portable ruggedized computer that integrates intercom communication, 4G, and BeiDou satellite positioning functions.

[0008] The specific technical solution adopted by this utility model is as follows:

[0009] A portable ruggedized computer includes a casing, inside which a processor unit, a heat dissipation system, and core functional modules are housed. The casing has physical interfaces. The core functional modules include a BeiDou positioning module, an intercom communication module, a cellular communication module, a main control computing unit, and a power management module.

[0010] The Beidou positioning module integrates a single-frequency, single-satellite system independent positioning GNSS unit, and is equipped with a low-noise amplifier.

[0013] The power management module has a built-in high-capacity lithium battery.

[0014] Preferably, the physical interfaces include USB 3.0, HDMI, Ethernet port, audio interface, and charging interface that supports a wide voltage input of 18V-26V.

[0015] Preferably, the panel of the casing integrates an emergency alarm indicator light, which alerts nearby personnel through sound and light when triggered.

[0016] Preferably, the processor unit drives the GPU to process graphics data through the PCIe interface and transmits it to the display screen via LVDS to complete the visualization output; at the same time, it directly connects to DDR memory and SDD storage to achieve high-speed data read and write, and also links the fan to ensure heat dissipation and drive the speaker to output audio;

[0017] By using the M.2 interface to carry the WiFi module and the PCIe interface to carry the 4G module, a network path is built. Relying on the UART serial port to connect to the Beidou positioning module and the intercom communication module, the information interaction capability in multiple scenarios is expanded.

[0018] Preferably, the processor unit sends instructions to the MCU of the sound and light alarm control board via RS232, and the MCU controls the buzzer to switch on and off according to the instructions.

[0019] Preferably, the processor unit communicates with the intercom module communication block via a universal asynchronous transceiver.

[0021] Preferably, the outer shell is made of high-strength hot-dip galvanized steel sheet with a conductive oxidation treatment on the surface.

[0022] Preferably, a copper heat dissipation module and a cooling fan are installed inside the casing. The internal heat is conducted to the copper heat dissipation module through heat pipes and discharged by the cooling fan. When running at full load, the surface temperature of the casing is ≤50℃.

[0023] Preferably, the power management module has a built-in high-capacity lithium battery, and the battery is equipped with overcharge / over-discharge / short circuit protection circuits.

[0024] This practical information has the following beneficial effects:

[0025] This invention provides a portable ruggedized computer with walkie-talkie, 4G, and BeiDou positioning capabilities. It offers multiple communication methods including walkie-talkie, 4G, and WiFi, meeting the comprehensive communication and positioning needs in complex environments such as field exploration and emergency rescue. Compared to traditional ruggedized computers, it reduces the number of devices users need to carry, improves operational efficiency, and enables real-time sharing of positioning information, rapid switching between walkie-talkie and telephone, and multi-mode communication complementarity (such as automatically switching to BeiDou short message transmission for critical data when no cellular network is available). It has significant practical value. Attached Figure Description

[0030] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and specific examples:

[0031] Combination Figure 1 As shown, a portable ruggedized computer includes a casing made of high-strength hot-dip galvanized steel sheet with a conductive anodized surface. Inside the casing, a copper heat dissipation module and a cooling fan are installed. Heat is conducted to the copper heat dissipation module via heat pipes. Under full load operation, the surface temperature of the casing is ≤50℃. The casing houses a processor unit, a cooling system, and core functional modules. Physical interfaces are located on the casing. The core functional modules include a BeiDou positioning module, a two-way communication module, a cellular communication module, a main control computing unit, and a power management module.

[0032] The BeiDou positioning module integrates a single-frequency, single-satellite system independent positioning GNSS unit. Positioning accuracy can reach 2.0 meters. It features a built-in low-noise amplifier, enabling high-sensitivity, high-precision positioning and rapid signal acquisition and tracking, ensuring excellent positioning performance even under weak signal conditions.

[0033] The intercom communication module supports digital intercom (DMR / PDT standard) and analog intercom (optional 136-174MHz / 400-470MHz frequency band), with a transmission power of 2W, a communication distance of ≥5 kilometers (line-of-sight environment), and a built-in noise reduction algorithm.

[0034] The cellular communication module integrates an LTE Cat 4 wireless communication module, meeting the requirements of wireless communication systems for data rate and connection reliability.

[0035] The main control computing unit is equipped with a processor (Intel Core i7 low-power version), 16GB or more of LPDDR4X memory and 512GB or more of industrial-grade SSD storage, and comes pre-installed with a customized operating system (supporting Windows 10 or Ubuntu).

[0036] The power management module has a built-in high-capacity lithium battery (17200mAh@22.2Wh, supporting fast charging protocols), and overcharge / over-discharge / short circuit protection circuits are set around the battery.

[0037] The physical interfaces include USB 3.0, HDMI, Ethernet, audio interface, and charging interface that supports a wide voltage input of 18V-26V.

[0038] The outer casing has an integrated emergency alarm indicator light on its panel, which alerts people in the vicinity with sound and light when triggered.

[0039] The processor unit drives the GPU to process graphics data through the PCIe interface and transmits it to the display screen via LVDS to complete the visualization output; at the same time, it directly connects to DDR memory and SDD storage to achieve high-speed data read and write, and also works with the fan to ensure heat dissipation and drive the speaker to output audio.

[0040] By using the M.2 interface to carry the WiFi module and the PCIe interface to carry the 4G module, a network path is built. Relying on the UART serial port to connect to the Beidou positioning module and the intercom communication module, the information interaction capability in multiple scenarios is expanded.

[0041] The processor unit sends instructions to the MCU of the sound and light alarm control board via RS232, and the MCU controls the buzzer switch according to the instructions.

[0042] The processor unit communicates with the intercom module communication block via a universal asynchronous transceiver.

[0043] The portable ruggedized computer uses a processor unit as its core hub. The processor unit drives the GPU to process graphics data via a PCIe interface and transmits it to the display screen via LVDS for visualization output. It also directly connects to DDR memory and SDD storage for high-speed data read / write, and is linked to a fan for heat dissipation and a speaker for audio output. For communication, it utilizes an M.2 interface to carry a WiFi module and a PCIe interface to carry a 4G module to build a network path. It relies on a UART serial port to connect to a Beidou module (positioning) and a walkie-talkie module (voice interaction), expanding its information interaction capabilities across multiple scenarios. For external interfaces, it integrates LAN (wired network), USB (peripheral expansion), HDMI (audio / video output), and MIC (audio input) ports to meet diverse connectivity needs. In the power management chain, after the lithium battery is charged, a stable power supply is provided via the power management board. This power supply supports the core processing board and various functional modules and also links with the audible and visual alarm control board to drive a buzzer, enabling status alarms and other interactive functions. The overall architecture, through a layered design of "core processing - communication expansion - peripheral interaction - power supply assurance - security alarm", achieves efficient collaboration of computing, storage, display, networking, power supply, and interaction capabilities, enabling ruggedized laptops to operate stably in complex environments and expand their multi-functionality.

[0044] Combination Figure 2 As shown, the control and execution process of the audible and visual alarm of the portable ruggedized computer includes power supply, communication interaction, and control execution. The processor unit sends commands to the MCU of the audible and visual alarm control board via RS232. The MCU controls the switching of the relay according to the commands. When the relay is closed, the buzzer circuit is activated, and the buzzer sounds an alarm; when it is opened, the alarm stops. Users can use the buzzer for early warning. Through secondary development, when the environmental information monitored externally exceeds the set value, the buzzer will alert surrounding personnel.

[0045] Combination Figure 3As shown, the processor unit communicates with the intercom communication module via UART (Universal Asynchronous Receiver / Transmitter). The processor unit, acting as the core control unit, transmits commands or data to the intercom module. The intercom module integrates multiple components working collaboratively: First, the LDO handles power conversion, regulating the input voltage to 3.3V to provide stable power to the MCU within the module; second, the MCU, as the control core of the intercom module, interacts with the digital intercom chip via the 8421 encoding protocol, performing functions such as signal parsing and logic control; third, the digital intercom chip handles voice signal processing and wireless transmission. An external MIC (microphone) collects voice input, which is modulated by the chip and then transmitted wirelessly via an ANT (antenna); simultaneously, the received wireless signal is demodulated by the chip and output as audio through a speaker. The entire architecture enables flexible control of the intercom module by the processor unit through UART communication. Utilizing a layered design for power management, encoding control, and RF transmission within the module, it completes functions such as voice intercom and signal interaction, ensuring efficient and stable system operation.

[0046] Combination Figure 4 The diagram shows the peripheral circuitry of the SIM interface for the 4G module. The ruggedized computer provides a SIM interface that conforms to ETSI and IMT-2000 specifications and supports 1.8V and 3.0V SIM cards. The USIM_DET pin enables hot-swapping of SIM cards and supports both low-level and high-level detection. When a SIM card is detected, the module executes a SIM card initialization program. After reading the SIM card information, the module registers with the network.

[0047] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
