[0032] With the advent of the Internet of Things era and the continuous advancement of national information industry innovation, the demand for "Internet of Everything", especially the industrial Internet, requires business scenarios with many links and large amounts of signal data. It is necessary to get rid of traditional cable deployment and wireless signal communication interval problems in mobile data collection scenarios. Traditional cold chain logistics information communication generally uses ZIGBEE communication transmission technology. Faced with multi-layer isolation such as metal compartments of cold chain vehicles and cargo storage boxes, there are problems of communication signal blocking and interruption in the signal collection process. As a result, a large number of cold chain companies still use traditional wired temperature sensing probes to collect the temperature of items in the compartment. The temperature sensing sensitivity is insufficient and easy to be intervened by humans. With the continuous improvement of scene requirements, the wirelessization of cold chain in-vehicle communication has also put forward higher requirements for wireless short-range communication technology in terms of low latency, high security and reliability, anti-interference, and large connections.

[0033] The utility model is based on cold chain transportation during road transportation, and is an innovative technology that applies information-based star flash communication technology to cold chain logistics.

[0034] Based on Huawei's NEARLINK technology, the utility model realizes wireless communication in a star topology structure between the on-board control unit (including the Sparklink management node G point) and the cold chain transport box read-write electronic tag (Starlink terminal access node T point) through SLE (Sparklink Low Energy), thereby realizing barrier-free high-speed communication in the Sparklink access network.

[0035] At the same time, the Star Flash access communication network management module in the vehicle control unit communicates with the 4G / 5G base station wireless network along the way through the Internet, and the satellite navigation module communicates with the satellite for positioning. The temperature / humidity, electronic waybills, real-time route conditions and other data information collected by the vehicle control unit are sent to the cold chain logistics monitoring platform server cluster. After analysis and processing by various modules of the software system, the temperature and humidity conditions of vehicles and cargo in cold chain transportation, actual route conditions and other information are finally distributed to the enterprise supervision center, operation platform management center, and government regulatory department.

[0036] The present utility model embodiment provides a cold chain logistics monitoring device. The cold chain logistics monitoring device and the cold chain transport vehicle provided in the embodiment of the present application will be described in detail below in conjunction with the accompanying drawings.

[0037] like Figure 1 As shown, the cold chain logistics monitoring device proposed in the embodiment of the utility model includes: the device includes: a vehicle-mounted control unit 1 and multiple Star Flash sensor access node modules 2; multiple Star Flash sensor access node modules 2 form a Star Flash access network 3 with a star topology structure in the compartment environment of the cold chain transport vehicle; the vehicle-mounted control unit 1 includes a Star Flash access communication gateway module, an embedded main control system and a GPS / Beidou navigation module; the embedded main control system is communicated with the Star Flash access communication gateway module and the GPS / Beidou navigation module respectively through the data serial port; the Star Flash sensor access node module 2 includes a temperature sensor and a humidity sensor, which are used to collect perception data in the compartment of the cold chain transport vehicle, and are communicated with the Star Flash access communication gateway module through the Star Flash access network.

[0038] More specifically, Figure 2 A schematic diagram of the relationship between cold chain transport modules provided by an embodiment of the utility model; Figure 3 For Figure 2 Corresponding cold chain transport data flow diagram, the utility model includes 4 basic units, namely A1. Vehicle-mounted control unit 1, A2. Star Flash sensor access node module 2 (T point), A3. Star Flash access network 3 (star topology structure), A4. Main application module.

[0039] Among them, the A1 unit is the main control unit for communication, mobile terminal data processing, and terminal interaction. The digital communication relationship of the main modules is composed of four parts, including the Star Flash access communication gateway module / management node (G point), embedded main control system, GPS / Beidou navigation module and 4G / 5G communication module. The Star Flash access communication gateway module / management node in A1 can effectively solve the loss rate caused by the compartment body through the Star Flash wireless spectrum reuse technology, and realize two-way perception communication with the A2 unit; on the other hand, the GPS / Beidou navigation module of the A1 unit can realize communication with the 4G / 5G signal of the road surface, and realize Internet communication data transmission interaction. The embedded main control system realizes the basic software and hardware integration of the terminal, and completes specific human-machine operation functions such as communication protocol, user interface, database, and business operation.

[0040] In the embodiment of the utility model, the embedded main control system adopts an embedded processor chip of ARM architecture.

[0041] More specifically, the vehicle control unit mainly includes three units: A1, A2, and A3, of which the core is the A1 unit. The core processor of the A1 unit is a domestically produced embedded processor chip with an ARM architecture. It is connected to the Star Flash management node module and the 4G / 5G communication module through data serial port communication, respectively, to realize the Star Flash low-frequency perception data communication inside the car and the 4G / 5G Internet data communication; the JTAG module is used to implement embedded programming instruction set calls and system debugging; the storage module temporarily stores embedded software application systems, embedded database systems, application data and other contents through FLASH solid-state flash memory; the LCD touch screen module is used to interact with the front-end graphical user interface to form an operation instruction set to drive the hardware integration unit to make a specific response.

[0042] In an embodiment of the utility model, the on-board control unit is installed in the cab of the cold chain transport vehicle, and the multiple star flash sensor access node modules are installed on the cargo storage box or on the cargo in the compartment of the cold chain transport vehicle.

[0043] In an embodiment of the utility model, the temperature sensor and humidity sensor are temperature and humidity RFID read-write electronic tags.

[0044] More specifically, A2 is the Star Flash sensor access node module (point T), which realizes the collection of sensory data such as temperature and humidity of the box and cargo, and realizes the automatic networking process in the compartment environment, forming A3. Star Flash access network (star topology). The A2 node (point T) transmits sensory data through the A3. Star Flash access network and the A1. vehicle control unit to achieve one-way data transmission, and performs Internet business processing through the 4G / 5G base station and the remote monitoring service cluster server, thereby completing A4. Main application modules, including: enterprise supervision data collection, platform operation, vehicle temperature and humidity monitoring, route correction monitoring, electronic orders and other specific functional units.

[0045] During the cold chain transportation process, the temperature / humidity sensors prefabricated on the cargo box or cargo will periodically transmit the collected periodic data from the multi-sensing node (point T) to the Xingshan management node (point G, or simply the management node) via the TCID routing transmission channel to achieve real-time perception of the temperature / humidity of cold chain cargo. Conversely, if the subscription of a sensing node (point T) fails or exceeds the warning parameter range, the management node (point G) can judge the temperature warning of a certain cargo and make timely intervention.

[0046] In the network architecture of Xingshan technology, the nodes in the system include management nodes (also called G nodes) and managed nodes (also called T nodes). The sensing nodes (T points) are mainly used to collect the temperature / humidity data of refrigerated / frozen goods in cold chain transport compartments. The Xingshan sensor access node communication supports multi-hop routing mechanism to form short-distance communication with the sensing nodes (T points), ensuring efficient business connection under the multi-hop network routing of multiple sensing nodes (T points). At the same time, the management node (G point) provides high-speed connection management, routing resource allocation management, information security encryption and other technical protocol interfaces at the data access layer, which are efficient, safe and anti-interference.

[0047] The management node (point G) is connected to the communication network management module through Xingshan, and transmits the temperature and humidity data acquisition signal of the sensing node (point T) to the embedded main control system. Among them, the embedded main control system includes: computing unit (ARM architecture CPU unit), storage unit (FLASH solid-state storage flash memory unit), input / output unit; after the temperature and humidity data acquisition signal is processed by the computing unit, it is integrated with the application software system through the embedded operating system software interface, and after the data is stored and the signal is output to the LED screen, the cold chain logistics data is displayed.

[0048] More specifically, the embedded main control system can also be connected to the GPRS / Beidou navigation module and the 4G / 5G communication module, which are used for navigation signals and network digital signals respectively. It can further realize real-time path tracking of cold chain vehicle navigation information, as well as 4G / 5G Internet communication, and realize data communication or data interaction with cloud servers.

[0049] In an embodiment of the utility model, the star flash sensor access node module uses SLE star flash low power consumption access.

[0050] More specifically, SparkLink provides two air interface access technologies: SparkLink Basic access SLB (SparkLink Basic) technology and SparkLink Low Energy access SLE (Sparklink Low Energy) technology. Taking into account the distance between cold chain logistics compartments and the need for long-distance driving, the A1-2.1.1 SparkLink SLE (Sparklink Low Energy) technology is used in the cold chain logistics transportation process. Through Polar channel coding under the SparkLink communication protocol, the A1-2.1.2 SparkLink wireless spectrum reuse technology is used to improve the low power consumption and high reliability of data transmission, and support stable data bandwidth communication capabilities under 1MHZ. Among them, before joining the SparkLink network, the multi-sensing node (T point) needs to confirm the validity of the T point device through authentication, and then the T point device will establish a TCID (dynamically allocated) routing transmission channel between T and G, thereby establishing a broadcast and subscription relationship between T and G. G point adopts a low-energy broadcast communication method based on all T points to achieve indiscriminate communication broadcast between G to T nodes.

[0051] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
