In the multi-party application of Xinli Technology, the wireless monitoring of refrigerators has become more and more perfect, and the realization of functions has gradually increased. The cooperation project with Huifenghua Trading in Beijing is a high-quality case of our wireless products used for refrigerator monitoring. The following This is the function implemented by our products in this project:
1. Monitor the temperature of the freezer in real time, and transmit the monitoring data to the monitoring center at the same time.
2. The on-site acquisition device and detection device use wireless transmission, with simple wiring and convenient installation.
3. Set the temperature upper and lower limit alarms, and remind the management personnel through the sound alarm.
4. Reliable, practical and economical, it is convenient for installation and maintenance by on-site technicians.
5. The device outputs standard Modbus protocol.
6. Historical data storage, report printing, data graph, historical alarm query, etc.
In this freezer wireless monitoring project, based on the communication and on-site monitoring environment, Xinli Technology uses wireless sensor network technology to design a matching combination scheme to dynamically monitor the internal temperature of the freezer, and transmit the monitoring information wirelessly to The monitoring background realizes real-time monitoring according to the requirements of the monitoring system.
The monitoring system is a layered distributed network structure, consisting of a three-layer structure of equipment layer, wireless network transmission layer and monitoring layer. The equipment layer is mainly composed of sensors (18b20 temperature probes); the wireless network transmission layer is mainly composed of six intelligent temperature sensors (wireless temperature Sensor), intelligent gateway (wireless management device) and other equipment; the monitoring layer is composed of main equipment such as computer and monitoring software. The schematic diagram of the system structure is as follows:
Notes:At present, the name of Xinli Technology’s wireless products has changed, and its functions have also been improved on the basis of the original. For details, please inquire for details. The product name “WN”, “ISN” has been renamed “XL”, and “wireless” has become “smart”. Make every effort to build a well-known brand of Xinli wireless sensor.
