DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] like Figure 1-4 As shown, this embodiment introduces a cold chain logistics transportation and transfer equipment, which is used to transfer goods that need to be refrigerated. The equipment mainly includes a refrigerated compartment 10 for storing goods, a refrigeration mechanism 11 for producing a cold source, and a cold air conduction mechanism 12 for transferring the cold source to the refrigerated compartment 10.

[0023] In order to facilitate real-time control of the temperature value in the refrigerated compartment 10, a number of temperature acquisition sensors 13 are evenly arranged on the upper and lower parts of the refrigerated compartment 10, and the central processing terminal for controlling refrigeration is connected to the temperature acquisition sensor 13 and the refrigeration mechanism 11 respectively. The temperature acquisition sensor 13 is connected to the vehicle-mounted driving recorder by wire, and the vehicle-mounted driving recorder is connected to the national networked and controlled enterprise monitoring platform and freight platform.

[0024] The vehicle-mounted driving recorder is installed in the cockpit, supports GSM / CDMA network, adopts GPS / Beidou dual-mode positioning, and is connected to the CAN data acquisition bus. It has location monitoring, speed monitoring, mileage statistics, IC card sign-in and sign-out, blind spot retransmission, SMS dispatch and voice broadcast, rapid acceleration / deceleration analysis, vehicle body signal detection, remote vehicle locking, etc. The vehicle-mounted driving recorder has its own speaker. When the temperature collected by the temperature acquisition sensor 13 exceeds the set threshold, it can sound and light alarm, and also send an alarm signal to the background server (or the department standard enterprise monitoring platform, freight platform).

[0025] The central processing terminal is connected to the temperature acquisition sensor 13 and the control end of the refrigeration mechanism 11 by any of the LoRa gateway, 4G / 5G network or WiFi network. In this embodiment, the LoRa gateway is preferably used for connection. The LoRa gateway uses the LoRa protocol for connection. LoRa is a low-power LAN wireless standard created by Semtech, a long-range radio.

[0026] A plurality of temperature acquisition sensors 13 located at the bottom of the refrigerated compartment 10 are embedded in a receiving chamber provided on the bottom plate of the refrigerated compartment 10. The detection probe of the temperature acquisition sensor 13 is not higher than the receiving chamber, and a dust and collision-proof net is covered on the top of the receiving chamber to ensure that the temperature acquisition sensor 13 will not be damaged when the goods in the refrigerated compartment 10 are stored.

[0027] The temperature acquisition sensor 13 uses a 485 digital temperature probe and is connected to the input end of the 485 digital temperature collector. Each 485 digital temperature collector can be connected to multiple 485 digital temperature probes. The output end of the 485 digital temperature collector is wired to the vehicle-mounted driving recorder, and the 485 digital temperature collector is connected to the central processing terminal using a wireless network (LoRa gateway, 4G / 5G network or WiFi network). If the 485 digital temperature collector does not have any valid connection, the temperature acquisition data is temporarily stored in the 485 digital temperature collector, up to 90,000. After connecting to the vehicle-mounted driving recorder and the central processing terminal, the uploaded data will be supplemented, and the data of the 485 digital temperature collector can also be exported through the data cable.

[0028] The cold air outlet end of the refrigeration mechanism 11 is connected to the cold air conduction mechanism 12, which is arranged at the upper part of the refrigerated compartment 10 and below the temperature collection sensor 13. An air curtain machine 14 is installed at the top of the rear end of the refrigerated compartment 10, and a wind shield curtain 15 is installed on the inner side of the air curtain machine 14.

[0029] The width of the air curtain 14 is the same as the inner width of the refrigerated compartment 10, and the air outlet of the air curtain 14 is vertically downward. The strong wind blown downward by the air curtain 14 forms a wind wall, which can effectively prevent the cold air in the refrigerated compartment 10 from escaping when the compartment door 16 is opened. The air curtain 14 is installed between the compartment door 16 and the wind shield 15 of the refrigerated compartment 10. The opening and closing of the air curtain 14 can be linked with the compartment door 16. When the compartment door 16 is opened, the air curtain 14 is automatically opened, and when the compartment door 16 is closed, it is automatically closed.

[0030] The upper end of the windshield 15 is installed on the top of the inner wall of the refrigerated compartment 10, and the lower end is located at the bottom of the refrigerated compartment 10. The windshield 15 is composed of a plurality of separate sheet-shaped flexible transparent plates, each of which is staggered and stacked to form an integral shielding plate for closing the rear of the refrigerated compartment 10. The windshield 15 can further prevent the cold air in the refrigerated compartment 10 from escaping outward.

[0031] The cold air conduction mechanism 12 includes a main air duct 121 and a branch air duct 122. One end of the main air duct 121 is connected to the cold air outlet end of the refrigeration mechanism 11, and the other end extends to the rear end of the refrigerated compartment 10. The branch air ducts 122 are symmetrically connected to both sides of the main air duct 121 and are communicated with the main air duct 121, and are arranged at equal intervals along the pipe direction of the main air duct 121; an electric opening and closing valve 124 for controlling the opening and closing of the branch air duct 122 is provided on the branch air duct 122 near the main air duct 121, and the electric opening and closing valve 124 establishes a control connection with the central processing terminal, and a plurality of air outlets 123 are opened at the lower end of the branch air duct 122. The temperature acquisition sensor 13 monitors the temperature of each area in the car in real time, and uploads the temperature acquisition data to the background server (the ministry-standard enterprise monitoring platform or the freight platform) in real time through the on-board driving recorder. When the car temperature collected by the temperature acquisition sensor 13 arranged in the refrigerated car 10 is higher than the preset value of the central processing terminal, the central processing terminal sends a control instruction to the refrigeration mechanism 11, the refrigeration capacity of the refrigeration mechanism 11 is increased, and the electric opening and closing valve 124 of the area where the temperature acquisition sensor 13 that monitors the temperature exceeding the preset value is located is opened, so that the branch air duct 122 on the electric opening and closing valve 124 is in an open state, and the cold air is transmitted to the area where the car temperature exceeds the preset value through the air outlet 123 on the branch air duct 122, so as to realize the temperature drop in this area.

[0032] Working process: When using the cold chain logistics transportation and transfer equipment, first place the refrigerated goods in the refrigerated compartment 10. In the initial stage, according to the refrigerated temperature requirements of the goods preset by the central processing terminal, the refrigeration mechanism 11 is turned on, the main air duct 121 and the branch air duct 122 are both in an open state, and cold air is continuously injected into the refrigerated compartment 10 through the cold air conduction mechanism 12 to reduce the temperature in the refrigerated compartment 10. The temperature collection sensor 13 monitors the temperature of each area in the refrigerated compartment 10 in real time. When the overall preset temperature in the refrigerated compartment 10 is reached, the refrigeration mechanism 11 is turned off, and the electric opening and closing valves 124 on the branch air duct 122 are all in a closed state.

[0033] When goods need to be loaded and unloaded, the wind curtain machine 14 is opened synchronously when the compartment door 16 is opened. The strong wind blown downward by the wind curtain machine 14 forms a wind wall. When the compartment door 16 is opened, the cold air in the refrigerated compartment 10 can be effectively prevented from escaping outwards. The wind shield 15 can also prevent the cold air in the refrigerated compartment 10 from escaping outwards.

[0034] The temperature acquisition sensor 13 transmits the real-time collected temperature data to the vehicle-mounted driving recorder and the central processing terminal. On the one hand, the vehicle-mounted driving recorder uploads the recorded vehicle location information, speed monitoring, mileage statistics, and the temperature data collected by the temperature acquisition sensor 13 in the refrigerated compartment 10 to the national network joint control department standard enterprise monitoring platform or freight platform. In addition, when the compartment temperature collected by the temperature acquisition sensor 13 arranged in the refrigerated compartment 10 is higher than the preset value of the central processing terminal, the central processing terminal sends a control instruction to the refrigeration mechanism 11, the refrigeration capacity of the refrigeration mechanism 11 is increased, and the electric opening and closing valve 124 of the area where the temperature acquisition sensor 13 monitoring the temperature exceeding the preset value is located is opened, so that the branch air duct 122 on the electric opening and closing valve 124 is in an open state, and the cold air is transmitted to the area where the compartment temperature exceeds the preset value through the outlet 123 on the branch air duct 122, so as to realize the temperature drop of the area, until the temperature value of the area drops to the preset value of the central processing terminal.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
