Technical Field

[0001] This utility model relates to the field of ship control, and in particular to an intelligent cloud terminal. Background Technology

[0002] Currently, the level of informatization and intelligence among inland waterway vessels is generally low. Most vessels still rely on manual operation and on-site maintenance in their operation and management, lacking effective linkage with remote platforms. However, with the development of Internet of Things (IoT) technology and the advancement of vessel electrification, the demand for data collection, remote monitoring, and intelligent management during vessel operation is increasing daily.

[0003] In practical applications, ship management not only requires communication between shipboard equipment and shore-based systems, but also interconnection with cloud platforms to enable centralized management, remote debugging, and intelligent control of operational data. Therefore, the need for integrated ship-shore-cloud infrastructure is becoming increasingly urgent.

[0004] However, existing ship terminal equipment is mostly a single-function module with limited communication methods and lacks deep integration with cloud platforms, resulting in problems such as low efficiency in ship equipment management and insufficient remote maintenance capabilities, making it difficult to meet the needs of modern inland waterway vessels in terms of intelligence and informatization. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides an intelligent cloud terminal that integrates a core processing module, a wireless communication module, a network module, a positioning module, and a power supply module. This enables the cloud platform to remotely manage device data through the terminal, thereby resolving the problem of the inability to quickly and flexibly control devices in existing technologies.

[0006] To achieve the above objectives, this utility model provides an intelligent cloud terminal, comprising: a core processing module, a wireless communication module, a network module, a positioning module, and a power supply module; the core processing module is connected to the cloud platform via the wireless communication module and communicates with relevant devices via the network module; the positioning module is connected to the core processing module and is used to receive and transmit location-related information; the power supply module is connected to the core processing module, the wireless communication module, the positioning module, and the network module respectively, and is used to supply power.

[0007] Further optionally, the core processing module includes a data update unit, which is used to receive new parameters sent from the cloud platform and write the new parameters into the relevant device.

[0008] Further optionally, the core processing module includes an over-the-air (OTA) download unit, which receives new firmware packages sent from the cloud platform, verifies them, and then upgrades its own firmware.

[0009] Further optionally, the core processing module includes a transparent transmission control unit, which is used to establish a transparent communication channel between the cloud platform and related devices.

[0010] Optionally, the intelligent cloud terminal may further include an expansion module: the expansion module is connected to the core processing module and is used to expand the functionality.

[0011] Further optionally, the expansion module includes one or more of the following: an indicator light unit, an alarm sound unit, and a temperature acquisition unit.

[0012] Alternatively, the core processing module may further include a debugging interface.

[0013] Optionally, the positioning module includes a BeiDou positioning unit for communicating with satellites.

[0014] Alternatively, the power module may include an overvoltage monitoring circuit.

[0015] Optionally, the core control module includes a verification unit for verifying the correctness of data packets.

[0016] The above technical solution has the following beneficial effects: By integrating a core processing module, a wireless communication module, a network module, a positioning module, and a power supply module within the cloud box, each module can work collaboratively under unified control, thereby achieving remote communication, device data interaction, location acquisition, and stable power supply; because the wireless communication module is connected to the core processing module, the terminal can establish a public network connection with the cloud platform, thus ensuring the timeliness of remote data upload and command reception; because the network module is connected to the core processing module, the terminal can conduct wired communication with shipboard equipment, thereby improving equipment management efficiency; because the positioning module is connected to the core processing module, the terminal can provide location and time information, thereby providing support for remote monitoring and management; because the power supply module is connected to each functional module respectively, it can ensure stable power supply, thereby improving the overall system reliability.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To address the issue of low device control efficiency in existing cloud platforms, this utility model provides an intelligent cloud terminal. Please refer to [link / reference]. Figures 1-2 , Figure 1 This is a schematic diagram of the communication relationship of the intelligent cloud terminal provided in this embodiment of the utility model; Figure 2 This is a schematic diagram of the structure of the intelligent cloud terminal provided in this embodiment of the utility model.

[0023] The intelligent cloud terminal provided in this embodiment includes: a core processing module 1, a wireless communication module 2, a network module 3, a positioning module 4, and a power module 5; the core processing module 1 is connected to the cloud platform through the wireless communication module 2 and communicates with relevant devices through the network module 3; the positioning module 4 is connected to the core processing module 1 and is used to receive and transmit location-related information; the power module 5 is connected to the core processing module 1, the wireless communication module 2, the positioning module 4, and the network module 3 respectively and is used to supply power.

[0024] like Figure 1 As shown, taking a ship control scenario as an example, the intelligent cloud terminal 10 is a physical control box, a ship-borne terminal box, installed on the target ship 40. It includes a housing, within which a core processing module 1, a wireless communication module 2, a network module 3, a positioning module 4, and a power supply module 5 can be integrated. All modules are uniformly scheduled and controlled through the core processing module 1.

[0025] The core processing module 1 is a circuit board unit based on an embedded system, preferably a single-chip microcomputer system based on the Linux embedded system, and the specific module used is Widora-BIT5. The core processing module 1 establishes a connection with the cloud platform 30 through the wireless communication module 2, and performs data interaction with the related equipment 20 (mainly PLC equipment in this embodiment) on the ship 40 through the network module 3. The core processing module 1 is responsible for running the internal program of the terminal, and driving other modules such as the positioning module 4, the wireless communication module 2 and the network module 3.

[0026] The wireless communication module 2 is electrically connected to the core processing module 1. As a public network communication unit, it can establish a secure connection with the cloud platform 30 to realize data upload and reception of remote instructions. The wireless communication module 2 can connect to the cloud platform 30 through a mobile communication network or a wireless local area network.

[0027] In one embodiment, the wireless communication module 2 is provided with a SIM card interface, so as to access the mobile operator network when using 4G communication; in another embodiment, the wireless communication module 2 is provided with a wireless network card unit, so as to access the cloud platform through a WiFi network. The wireless communication module 2 can interact data with the core processing module 1 through the AT instruction interface, so as to realize a stable communication link.

[0028] The cloud platform 30 is a remote management platform matching the intelligent cloud terminal 10. The cloud platform 30 is usually disposed in a remote server or a data center, configured to store and manage the received device data, and issue control instructions to the intelligent cloud terminal 10. When the intelligent cloud terminal 10 connects to the cloud platform 30, and when a client (mobile phone terminal, computer terminal, etc.) connects to the cloud platform, two-way verification of user name and password is required to ensure data security. Operators can send quality and receive information to the cloud platform through the mobile phone terminal or the computer terminal.

[0029] The network module 3 is configured to realize the connection between the intelligent cloud terminal and the ship local area network, so as to facilitate data interaction between the terminal and related equipment on the ship. In one embodiment, the network module 3 includes an Ethernet interface, which can establish a stable wired communication link between the terminal and the shipborne PLC device.

[0030] The network module 3 can support standard industrial communication protocols, so as to ensure that the core processing module 1 can reliably access and exchange the operating parameters of related equipment. Through the network module 3, the intelligent cloud terminal can realize the access to related equipment, thereby providing necessary interface support for remote data upload and execution of instructions issued by the cloud platform.

[0031] The positioning module 4 is electrically connected to the core processing module 1. The positioning module 4 may include a satellite positioning chip and a positioning antenna connected to it, used to receive positioning signals from satellites and generate location information including latitude, longitude, speed, and time parameters. The positioning module 4 transmits the acquired location information to the core processing module 1, enabling the intelligent cloud terminal to have the ability to sense the ship's position and time, thereby ensuring that accurate location information is included when the device data is uploaded to the cloud platform.

[0032] The power module 5 is housed within the casing and is electrically connected to the core processing module 1, the wireless communication module 2, the positioning module 4, and the network module 3. The power module 5 converts and regulates external input power, providing the necessary DC power to each functional module. The power module 5 may include voltage regulation and protection circuits to ensure a stable power supply to each module even under voltage fluctuations or abnormal conditions, thereby guaranteeing the reliable operation of the intelligent cloud terminal.

[0033] The following is a typical workflow for the operation of an intelligent cloud terminal:

[0034] 1. Positioning module 4 receives satellite signals, generates raw data packets containing information such as latitude, longitude, speed, and time, and uploads them to core processing module 1 via serial interface (UART);

[0035] 2. The core processing module 1 reads and parses the uploaded data packets, makes a preliminary judgment on the correctness of the data, and updates the internal time / location parameters if there are no errors. If there are any errors, it prepares to report them directly.

[0036] 3. After the set reporting period is reached, the core processing module 1 combines information such as time, location, speed, SIM card status, and signal into a data packet containing the MQTT network, and sends it to the wireless communication module 2 via AT commands.

[0037] 4. Wireless communication module 2 connects to the cloud platform and reports MQTT data packets.

[0038] 5. The core processing module 1 periodically receives instructions sent by the cloud platform through the wireless communication module 2 and performs operations according to the instructions.

[0039] It should be noted that, for security reasons, all port access is closed because the cloud box device does not need to be actively connected to by any device. Furthermore, on the local area network (LAN) side, the cloud box device acts only as a server, requesting connections to specific LAN device IPs and ports, and only accepting specific packets, discarding others. On the public network side, the cloud box device acts only as a client, connecting to the cloud platform and the internal server used for pass-through. Connecting to the cloud platform requires both username and password authentication. The content sent and received by the internal server used for pass-through is not processed by the cloud box; in the event of abnormal network packets, the connection will be disconnected to ensure security.

[0040] As an optional implementation, the core processing module 1 includes:

[0041] The data update unit 101 is used to receive new parameters sent from the cloud platform and write the new parameters into the relevant devices.

[0042] The data update unit 101 is located within the core processing module 1 and is electrically connected to the wireless communication module 2 and the network module 3. When it receives an instruction from the cloud platform, the data update unit 101 can receive new parameters (such as destination, speed, turning radius, etc.) sent by the cloud platform through the wireless communication module 2, and transmit the received new parameters to the network module 3. The network module 3 then writes the parameters to relevant devices (such as PLC controllers on ships) via the S7 protocol through the local area network.

[0043] In one implementation, the data update unit 101 includes a data cache circuit and a data write interface circuit. The data cache circuit is used to temporarily store newly received parameters to ensure that the data is stable and reliable during the writing process; the data write interface circuit corresponds to the interface of the network module 3 to ensure that the parameters can be accurately transmitted to the field device.

[0044] As an optional implementation, the core processing module 1 includes:

[0045] The over-the-air download unit 102 is used to receive new firmware packages sent from the cloud platform, verify them, and then upgrade its own firmware.

[0046] The over-the-air (OTA) download unit 102 is electrically connected to the wireless communication module 2. Upon receiving an instruction from the cloud platform, it enters OTA mode. The OTA download unit 102 receives the new firmware package transmitted from the cloud platform via the wireless communication module 2 and verifies the package. After successful verification, the OTA download unit 102 writes the new firmware package into the memory of the core processing module 1, thus upgrading the firmware. Afterwards, it automatically restarts the cloud terminal and reports the upgrade log to the cloud platform.

[0047] In one embodiment, the over-the-air download unit 102 includes a data receiving interface circuit, a verification circuit, and a write control circuit. The data receiving interface circuit is used to receive firmware packages from the wireless communication module 2; the verification circuit is used to verify the integrity and correctness of the firmware packages; and the write control circuit is connected to the memory of the core processing module 1 and is used to write the verified firmware packages into a designated storage area.

[0048] By setting up an over-the-air download unit 102 in the core processing module 1, the intelligent cloud terminal can be equipped with remote firmware upgrade capability, thereby avoiding manual on-site operation, improving the system maintenance efficiency and the timeliness of updates, and ensuring the reliability of equipment operation.

[0049] As an optional implementation, the core processing module 1 includes:

[0050] Transparent transmission control unit 103 is used to establish a transparent communication channel between the cloud platform and related devices.

[0051] The transparent transmission control unit 103 is electrically connected to the wireless communication module 2 and the network module 3. After receiving a transparent transmission command from the cloud platform, the transparent transmission control unit 103 opens its port to connect to the cloud platform via TCP, allowing developers to remotely debug and control the PLC using S7 software. The transparent transmission control unit 103 puts the core processing module 1 into transparent transmission mode, thereby establishing a transparent communication channel between the cloud platform and related devices.

[0052] In one embodiment, the transparent transmission control unit 103 includes a port control circuit and a data forwarding circuit. The port control circuit is connected to the interfaces of the wireless communication module 2 and the network module 3, and is used to open or close a specified communication port; the data forwarding circuit is used to directly forward the data packets received by the wireless communication module 2 to the network module 3, and at the same time, directly forward the return data from the network module 3 to the wireless communication module 2, thereby realizing transparent data transmission without core program processing.

[0053] By setting a transparent transmission control unit 103 in the core processing module 1, the intelligent cloud terminal can have remote transparent transmission debugging capabilities. Developers can establish a debugging link directly with the field equipment through the cloud platform, avoiding the complex configuration of VPN or port mapping in the traditional method, thereby improving the efficiency of remote maintenance and reducing the operation and maintenance cost.

[0054] After the cloud platform issues a remote debugging command, the cloud box device will enter a transparent transmission state, connecting to the internal server and the field device server. Because the internal server has port forwarding service pre-configured, when a connection control is made to the internal server address, the corresponding network packets will be transmitted to the field device, and the field device's response will also be transmitted back to the control software, realizing remote control.

[0055] As an optional implementation, an extension module 6 is also included:

[0056] The expansion module 6 is connected to the core processing module 1 to expand the functionality.

[0057] The intelligent cloud terminal also includes an expansion module 6, which is electrically connected to the core processing module 1. The expansion module 6 is located inside or on the surface of the cloud terminal's housing and is used to enable extended applications of the terminal.

[0058] As an optional implementation, the expansion module 6 includes one or more of the following: indicator light unit 601, prompt sound unit 602, and temperature acquisition unit 603.

[0059] In one embodiment, the expansion module 6 includes one or more of an indicator light unit 601, an alarm sound unit 602, and a temperature acquisition unit 603. The indicator light unit 601 indicates the working status of the terminal through light signals; the alarm sound unit 602 provides operation or alarm information through sound signals; and the temperature acquisition unit 603 acquires ambient temperature information through a temperature sensor interface and transmits it to the core processing module 1.

[0060] By setting up an extension module 6 outside the core processing module 1, auxiliary functions can be added according to different usage scenarios, thereby improving the applicability and scalability of the smart cloud terminal.

[0061] As an optional implementation, the core processing module 1 also includes a debugging interface 7.

[0062] The debugging interface 7 is connected to the core processing module 1 circuit and is used to realize local maintenance and debugging of the equipment.

[0063] In one embodiment, the debugging interface 7 can be located on the outer surface of the housing and connected to external debugging tools via a connecting cable, thereby facilitating hardware-level testing and adjustment by maintenance personnel. The debugging interface 7 can take the form of a standard serial interface, a USB interface, or a dedicated hardware pin interface.

[0064] As an optional implementation, the positioning module 4 includes a BeiDou positioning unit for communicating with satellites.

[0065] Positioning module 4 includes a BeiDou positioning unit, which can establish a communication connection with satellites to receive satellite signals and output positioning data containing latitude, longitude, speed and time information.

[0066] In one embodiment, the BeiDou positioning unit may include a BeiDou positioning chip and an antenna connected to it. The antenna is positioned at an appropriate location on the housing to ensure the quality of positioning signal reception. The BeiDou positioning unit is connected to the core processing module 1 via a serial interface (such as a UART interface) to transmit the received positioning data to the core processing module 1.

[0067] As an optional implementation, the power module 5 includes an overvoltage monitoring circuit.

[0068] An overvoltage monitoring circuit is installed at the input terminal of power module 5 or in the voltage regulator circuit to monitor the input power supply voltage in real time.

[0069] In one embodiment, the overvoltage monitoring circuit can adopt a combination structure of Zener diode, voltage comparator or dedicated power protection chip. When the input voltage is detected to exceed the preset threshold, the overvoltage monitoring circuit can cut off or limit the power output in time, thereby preventing the core processing module 1, wireless communication module 2, network module 3 and positioning module 4 from being damaged due to abnormal voltage.

[0070] As an optional implementation, the core control module includes a verification unit 104 for verifying the correctness of data packets.

[0071] The verification unit 104 is mounted on the circuit board of the core processing module 1 and connected to the data receiving circuit. The verification unit 104 is used to determine the correctness of the received data packets.

[0072] In one embodiment, the verification unit 104 includes a verification logic circuit and a buffer circuit. The verification logic circuit can compare data packets based on preset verification rules (such as cyclic redundancy check, parity check, etc.) to determine whether the data is complete or contains errors; the buffer circuit is used to temporarily store data during the verification process to ensure the accuracy and stability of the verification results.

[0073] The above technical solution offers the following advantages: By integrating a core processing module, wireless communication module, network module, positioning module, and power supply module within the cloud box, the terminal can achieve remote communication, device interaction, positioning, and stable power supply, thus solving the problems of dispersed equipment structures and low management efficiency in existing systems. The core processing module includes units for data updates, over-the-air downloads, transparent transmission debugging, and verification, enabling the terminal to perform remote parameter updates, firmware upgrades, and transparent transmission, thereby reducing manual on-site maintenance and improving management efficiency. The expansion module adds indicator lights, audible alerts, and temperature acquisition units, allowing the terminal to adapt to diverse application scenarios, thus enhancing the system's scalability and applicability.
