Temperature and humidity monitoring host JCJ901K agricultural product cold chain warehouse monitoring

1RegardingJCJ902KNational agricultural product cold chain warehouse monitoring host

JCJ902K includes wireless temperature and humidity/temperature sensors/wireless door magnetic sensors and a cold chain warehouse touch screen host. The collected data can be directly transmitted to the National Agricultural Product Cold Chain Standardization Cloud Platform of the Ministry of Commerce through WIFI communication. The host comes with a large capacity data storage and adopts data interruption and continuation technology to ensure that data lost due to poor communication network or transmission interruption will not be lost after communication is restored to normal. The product comes with a voice alarm function.

Application scenarios:Can be used for pilot and demonstration enterprises of national agricultural product cold chain standardizationCold chain warehouseCold cabinets, various display cabinetswaitcold chainenvironmentDetecting and uploading parameters such as temperature and humidity, door opening and closing to the national platform.

3Product Features

hostScreen features：

1. All human-computer interactions of the device are operated through touch screen, with visual icons and clear Chinese character prompts, making it convenient for users to learn and apply; 3.5-inch TFT true color screen, adjustable screen brightness; When there is no operation, the screen can be automatically turned off to enter power-saving mode, and the shutdown time can be set by the user.

2. Automatic recording and storage function for temperature and humidity data, with built-in large capacity data storage, recording data once per minute can continuously record data for more than 3 months. Record count≧5Ten thousand pieces.

3. Data export adopts MicroUSB interface, compatible with Android phone data cable. It can export equipment historical data, analyze data curves, and export PDF or Excel format files again. The various parameters of the device can be configured on the computer.

4. One click flashing function: This device is an intelligent device terminal, and users only need to make one purchase. System upgrades or function upgrades do not require investing new funds to purchase new devices. The intelligent terminal supports one click flashing function, and intelligent monitoring hardware devices can be upgraded and replaced through simple operations.

5. Host online flashing function: When the host is connected to the network, it can upgrade the firmware by itself through the network. When the device needs to upgrade firmware, users do not need to participate in the operation to complete the online upgrade of the device.

6. Equipped with user-friendly device configuration and data reading software, the software is a pure green version that does not require installation. USB is plug and play, eliminating the hassle of installing software and drivers for users.

7. The intelligent terminal screen is equipped with a large capacity backup battery, and the battery circuit comes with overcharge and overdischarge protection circuits, so users do not have to worry about battery damage caused by overcharging or overdischarging. After the terminal stops external power supply, the backup battery can continue to work for more than 12 hours (tested with the screen display turned off).

8. The host screen alarm is divided into two levels: warning and alarm. Users can freely set the alarm values for both levels, with various alarm methods, including numerical color alarm, voice prompt alarm, alarm voice, and adjustable sound alarm volume.

9. Users can view historical data and curves at any time period through the host screen. The historical curves are automatically played back in playback mode, and the playback speed can be freely set by users. Users can choose whether to display the curve for temperature or humidity, and calculate the maximum and minimum values for this period.

10. The time interval for data collection, recording, and uploading to the server can be adjusted by users according to the requirements of the Ministry of Commerce platform in terms of time, minutes, seconds, and at will.

11. Host installation form: It can be directly fixed to the wall with screws through the back plate. The host screen itself can be slid up and down and removed separately, making it convenient for users to remove the device at any time.

12. The host screen is connected to the on-site WIFI network and uses a reliable communication algorithm protocol that meets the communication requirements of the national agricultural product cold chain platform. Communication interruption ensures that data is not lost. After automatic reconnection, data will be continuously transmitted to the cold chain platform. The program comes with a mechanism to prevent unstable wireless sensor signals and data loss.

13. Each host screen can simultaneously match 8 wireless temperature and humidity sensor measuring points or 8 single temperature wireless sensor measuring points and 8 wireless door magnetic monitoring sensors; The alarm limits for multiple connected measurement points can be set separately.

For the purpose of user level supervision, all parameter configuration interfaces of the device are set with user login password permissions. Users must have a password to enter and modify parameters. There are no password restrictions on real-time data display and data query interfaces and other viewing functions.

15. The device has the function of quickly viewing data, and it will automatically generate data segments during the startup process every time the device is turned on or off. If users need to view, they do not need to enter the start and end time of the startup and shutdown, and can directly select the corresponding time period to view or print, which is very convenient.

16. The device has the function of automatically synchronizing the server time with the clock.

17. The device information is displayed on the screen *, which can show the WIFI signal strength in real time (the closer the WIFI strength value is to 0, the better the signal, and generally stable communication can be achieved with a signal strength of -90 or above), battery life, and storage capacity; Real time display of temperature and humidity values, alarm and warning status, and door opening and closing status, including year, month, day, hour, minute, second, and week information.

18. Sensor data is wirelessly transmitted to the host device, making it easy for users to install and fix, eliminating a lot of annoying line connections, and reducing the risk of system failures due to line faults. Note: For cold storage applications, generally the cold storage is a double-layer metal skin structure, with equipment screens installed outside the cold storage and sensor measuring points installed inside the cold storage. To prevent sensor signals from being blocked by the cold storage, the RF antenna of the equipment screen needs to be a separate suction cup antenna, which is installed and fixed inside the cold storage.

Supporting sensor measuring points:

19. The signal transmission between the sensor measuring point and the intelligent terminal screen adopts wireless RF signal transmission. The sensor is powered by a battery and easy for users to install without wiring. Wireless sensor signal transmission over 500 meters in open spaces.

20. The supporting sensor measuring points are powered by disposable batteries, which can be used continuously for more than 1 year after each battery replacement (data is collected every 10 seconds), saving users the trouble of frequent charging.
