Description

Technical Field

[0001] This application relates to the field of mobile cold storage technology, and in particular to a pre-cooling management information system for fruits and vegetables based on mobile cold storage. Background Technology

[0002] Mobile cold storage, also known as modular cold storage, portable cold storage, or assembled cold storage, is a small to medium-sized refrigeration and air conditioning unit with refrigeration and insulation functions that can be combined and assembled. The working principle of mobile cold storage is mainly based on a compressor refrigeration cycle. The compressor draws in low-temperature, low-pressure refrigerant gas and compresses it into high-temperature, high-pressure gas, then releases heat into the atmosphere, causing the refrigerant gas to condense into a liquid. Next, it passes through an expansion valve to reduce pressure and temperature, becoming low-temperature, low-pressure wet vapor that enters the evaporator. There, it absorbs heat from the stored goods and evaporates back into a gaseous state, completing the heat absorption process. This cycle is repeated to meet the needs of preserving and freezing goods.

[0003] Fruits and vegetables are particularly sensitive to temperature and humidity, so mobile cold storage is needed for their transportation and storage.

[0004] However, traditional mobile cold storage facilities used for transporting and storing fruits and vegetables have low levels of information technology and lack real-time monitoring and online management capabilities.

[0039] Example 1:

[0040] See Figure 1 A pre-cooling management information system for fruits and vegetables based on mobile cold storage, the system comprising:

[0041] Temperature and humidity detector 101 is installed inside the mobile cold storage and is used to acquire, transmit and display the temperature and humidity inside the mobile cold storage.

[0042] The cloud server 102 is network-connected to the temperature and humidity detector 101 and is used to receive, store and transmit data sent by the temperature and humidity detector 101.

[0043] The smart terminal device 103 is network connected to the cloud server 102 and is used to receive, call, store and display data sent by the cloud server 102.

[0044] Specifically, the temperature and humidity detector 101 measures the temperature and humidity inside the mobile cold storage and converts the measurement results into corresponding electrical signals. After processing, these electrical signals can be directly displayed on a screen showing the current temperature and humidity values, or output to other devices for further processing and analysis via an interface. In this embodiment, the detection signals from the temperature and humidity detector 101 are transmitted to a cloud server 102 via a network. The cloud server 102 receives the data sent in real time by the temperature and humidity detector 101, stores and processes the collected data from inside the cold storage, and transmits the analyzed data to a smart terminal device 103 for display. Additionally, the data can also be stored on the smart terminal device 103.

[0045] The pre-cooling management information system has pre-set algorithms and rules. When the temperature and humidity values ​​inside the cold storage exceed the preset range, the manager adjusts the refrigeration equipment inside the cold storage through the smart terminal device 103, changing the environmental parameters inside the storage to maintain the temperature and humidity environment required for fruits and vegetables. In this way, the manager can remotely monitor and manage the status of the cold storage in real time through the smart terminal device 103.

[0046] In this embodiment, the real-time monitoring and online management of the mobile cold storage are realized through the cooperation of the temperature and humidity detector 101, the cloud server 102 and the smart terminal device 103. By remotely adjusting the environmental parameters inside the mobile cold storage, the temperature and humidity environment required by the fruits and vegetables can be maintained, thereby reducing the risk of quality problems in the fruits and vegetables during transportation and storage.

[0047] Furthermore, for delivery environments under abnormal conditions, the pre-cooling management information system establishes a new optimized risk pre-assessment decision-making system to identify possible abnormal situations and set corresponding weight ratios for different influencing factors, so as to minimize the risk weight index of the final impact on agricultural products, thereby selecting the optimal solution with the lowest loss.

[0048] The cloud server 102 stores the collected data in a database and uses data analysis algorithms to evaluate and optimize the pre-cooling effect. All data during the pre-cooling process is recorded in detail and stored in the database, facilitating subsequent data analysis and traceability. This enables full-process quality traceability of agricultural products, allowing for real-time access to product status information and ensuring a traceable supply chain. Furthermore, it provides full-process supervision of agricultural product transactions, ensuring product quality and addressing agricultural product safety issues.

[0049] In addition, this utility model effectively utilizes warehouse space, improves the efficiency of relevant logistics links, and reduces costs caused by product damage and spoilage.

[0050] Example 2:

[0051] See Figure 2 and Figure 3 Based on Embodiment 1, optionally, the temperature and humidity detector 101 includes:

[0052] The temperature and humidity sensor 202 typically uses an integrated temperature and humidity probe as the sensing element. It collects temperature and humidity signals, processes them through circuits such as voltage regulation and filtering, operational amplification, nonlinear correction, V / I conversion, constant current, and reverse protection, and then converts them into current or voltage signals linearly related to temperature and humidity. Alternatively, it can directly output via RS485 or RS232 interfaces through the main control chip. The temperature and humidity sensor 202 can collect temperature and humidity data and upload it to a cloud server via WIFI / Ethernet. By fully utilizing existing WIFI / Ethernet communication networks for data acquisition and transmission, it achieves centralized monitoring of temperature and humidity data, significantly reducing construction work, improving construction efficiency, and lowering maintenance costs.

[0053] The MCU201 is connected to the temperature and humidity sensor 202 via an I / O port, and is used to receive the digital signals output by the temperature and humidity sensor 202, and process, analyze and store them.

[0054] Communication module 2 is connected to the MCU201 via a network interface.

[0055] Specifically, the communication module includes a WIFI module 205 and an Ethernet module 206, and the network interface includes a WIFI interface 203 and an Ethernet interface 204; wherein, the Ethernet interface 204 is used to connect to the Ethernet module 206, and the WIFI interface 203 is used to connect to the WIFI module 205.

[0056] The MCU201 is connected to the temperature and humidity sensor 202 to collect temperature and humidity data in the warehouse; the MCU201 is connected to the WIFI module 205 through the WIFI interface 203, or the MCU201 is connected to the Ethernet module 206 through the Ethernet interface 204, to transmit the collected data to the cloud server 102 through the network.

[0057] The temperature and humidity detector 101 provides two different network interfaces based on WIFI and Ethernet, enabling the temperature and humidity detector 200 to adapt to different network environments. Depending on the needs, different networks can be accessed by changing the network interface instead of using the device, making it convenient and highly usable for users to monitor the status of their goods in the warehouse on different terminal devices.

[0058] Optionally, the temperature and humidity detector 101 further includes:

[0059] The audible and visual alarm module is connected to the I / O port of the MCU201;

[0061] The power supply module is used to supply power to the MCU201, communication module, audible and visual alarm module, and display module.

[0062] Optionally, the MCU201 is an STC89C52-35I-LQFP44 microcontroller.

[0063] Optionally, the smart terminal device 103 is a smartphone, tablet, or laptop.

[0064] Optionally, the temperature and humidity sensor 202 is a DHT11_C87032 sensor.

[0065] Specifically, the circuit diagram of the temperature and humidity detector 101 is shown in the attached instruction manual. Figure 3As shown: S1 is a DHT11 sensor. The DHT11_C87032 is a digital temperature and humidity sensor that can directly transmit the collected ambient temperature and humidity data digitally. The DHT11 uses single-bus communication, so only one I / O port of the microcontroller needs to be connected to the DHT11's communication interface to achieve data acquisition and transmission. U1 is an MCU201, i.e., a microcontroller (also called a single-chip microcomputer), using an STC89C52-35I-LQFP44 microcontroller. Connector MK1 uses an NRF24L01P wireless transceiver chip. Connector MK1 is the terminal block for Ethernet interface 204. Ethernet module 206 uses a U4 Ethernet module. Connector S1 is the connection interface for temperature and humidity sensor 202. U2 is a voltage regulator chip used to convert the 5V input voltage to 3.3V to power Ethernet module 206. The Ethernet module 206 can be replaced with a WIFI module 205 according to user needs.

[0066] When the environmental parameters inside the cold storage exceed the preset values, the audible and visual alarm module is triggered. The display module shows the temperature and humidity inside the storage. The voltage regulator chip in the circuit stabilizes the power supply voltage, ensuring stable operation of the equipment under various power conditions. The crystal oscillator provides a stable clock signal. The reset circuit is used to reset critical components such as the microcontroller to their initial state when the equipment malfunctions or needs to be restarted, so that the equipment can resume normal operation.

[0067] This invention introduces a pre-cooling management information system for fruits and vegetables based on mobile cold storage, perfectly combining remote control technology with fruit and vegetable preservation. The platform not only provides users with the convenience of remotely controlling preservation equipment via mobile app or PC, but also enables real-time access and management of resources through cloud servers. This system utilizes technological means to significantly improve the management level of the fruit and vegetable preservation process. By precisely controlling preservation process parameters, we can ensure that fruits and vegetables maintain optimal quality throughout the entire preservation process. Through centralized management and real-time monitoring, we significantly reduce operation and maintenance costs and greatly improve work efficiency. More importantly, this platform breaks down information barriers between traditional subsystems, laying a solid foundation for intelligent cold chain information management. Through data monitoring, analysis, and early warning, we can conduct precise remote management and control, providing enterprises with a more intelligent cold chain information management solution. This not only helps enterprises improve their comprehensive management capabilities but also ensures the quality and safety of fruits and vegetables throughout the entire cold chain process, meeting consumers' demand for high-quality fruits and vegetables.
