Low temperature helps maintain the original quality and flavor of seafood, and at the same time prolongs the fresh-keeping cycle of seafood products. Therefore, in the cold chain transportation of seafood products, the refrigeration temperature is generally required to be between -18°C and -23°C.
The temperature and humidity monitoring system for seafood cold chain transportation is composed of two parts: monitoring points and management cloud platform. The embedded temperature and humidity recorder is used to monitor the temperature and humidity in the refrigerated compartment for seafood transportation in real time, and the data is uploaded by 4G wireless communication. To remote monitoring cloud platform.
Seafood Cold Chain Transportation Temperature and humidity monitoring System composition
1. Temperature and humidity monitoring equipment: an embedded temperature and humidity transmission recorder that uses 4G/GPRS wireless communication technology to upload data.
(1) Using the original Swiss temperature and humidity measurement unit, it has the characteristics of excellent measurement performance, high accuracy and strong anti-interference ability. It can quickly and uninterruptedly monitor the temperature and humidity changes in the refrigerated compartment.
(2) The temperature and humidity recorder comes with GPS positioning and speed recording (optional) functions, which can monitor the running track and running speed of the equipment in real time. The running speed can also be related to time, real-time temperature and humidity, remaining power, power supply status, and storage. The amount of data, battery power, signal strength and other information are displayed in real time on the LCD screen.
(3) The device has a built-in buzzer, and the shell is designed with buttons. Before use, add the temperature limit by pressing the button. If the temperature exceeds the limit during the monitoring process, the device will give a sound and light alarm. At the same time, the built-in mobile phone card will send an alarm to the added contact by means of text messages, ringing, etc.
(4) The monitored cabin temperature and humidity, vehicle running track, running speed and other information will be uploaded to the environmental monitoring platform through the 4G signal for real-time display and storage.
(5) The recorder is equipped with a large storage capacity chip, which can store up to 65,000 sets of data, and has three storage modes: prohibit, open and automatic. When the storage mode of the device is automatic, the device will automatically store the monitoring data if there is a signal interruption or other special circumstances, and the stored data will be transmitted after it is restored to normal to ensure the continuous and complete monitoring of the entire cold chain.
(6) This device supports connecting to a Bluetooth printer via Bluetooth to realize one-key printing.
The working technical parameters of the embedded temperature and humidity transmission recorder:
Parameter configuration method: SMS setting
Probe working temperature and humidity: -40℃~80℃, 0%RH-100%RH
Temperature and humidity response time: ≤8s (1m/s wind speed), ≤25s (1m/s wind speed)
Temperature and humidity display resolution: 0.1℃, 0.1%RH
Backup battery working time: ≥2 days (with GPS), ≥7 days (without GPS positioning)
Long-term stability of temperature and humidity: ≤0.1℃/y, ≤1%RH/y
Remote monitoring cloud platform
The environmental monitoring cloud platform is based on the B/S module and is developed with a visual programming language. It provides a visual monitoring operation interface and adopts the Window interface style design. It is the remote monitoring center of the seafood cold chain temperature and humidity monitoring system. Through the platform manager, you can remotely manage all monitoring equipment, add and modify the temperature and humidity limits, select the opening and closing of multiple alarm methods such as telephones and mobile phones, and the settings of multi-level authority access.
The functions of the seafood cold chain temperature and humidity monitoring system
(1) Temperature and humidity monitoring: Use temperature and humidity monitoring equipment to monitor the ambient temperature and humidity in real time, and set the temperature limit in advance. If the temperature exceeds the limit, the system will first add the management personnel to the platform via phone calls, text messages or Send alarm information by email.
(2) Whole process tracking: Managers can log in to the cloud platform through web pages, WeChat official accounts, mobile phones and other terminals, and view real-time and historical data of temperature and humidity during the cold chain transportation of seafood in the form of numbers, dashboards, curves, etc. through the display interface ; On the ground interface, view the current location of the device, the historical trajectory of vehicle movement and real-time speed and other information.
in conclusion
Since the compartment of the refrigerated truck is separated from the driver’s cab, it is also very important for the managers in the driver’s compartment to grasp the temperature and humidity changes in the refrigerated truck in time. The embedded temperature and humidity transmission recorder can be sent by SMS. It can be set to add the mobile phone numbers of up to 5 persons responsible for the alarm and the alarm interval. When the device communication is normal, if the mobile phone receives the SMS reply from the recorder, it means The number is added successfully. If the value exceeds the limit, the recorder will send an alarm message to the management personnel in the cab as soon as possible.
The seafood cold chain temperature and humidity monitoring system uses GPRS technology to remotely monitor the temperature and humidity of the entire environment of the seafood cold chain. In the event of an abnormality, timely measures can be taken to avoid the deterioration of the seafood, and early warning can be achieved to ensure the quality of the seafood; handover When shipping goods, the transporter will print the historical data of the cold chain to the consignee through the Bluetooth printer, which is beneficial to improve the credibility of the enterprise.
