Case introduction:
1. Program description
Blood and vaccines must be kept at the correct temperature during storage and transportation to ensure that their quality meets the strict requirements of medical clinical applications; similarly, food must be kept at a certain temperature during transportation in order to keep fresh and high-quality The food was successfully transferred from the supplier to the consumer.
The data collection and transmission of traditional temperature control equipment is not only easily affected by the installation environment, including the power supply and transmission network, but also has poor stability, which often leads to false alarms, wastes manpower, and affects the quality of transportation and storage resources.
BisWin2.45G temperature and humidity label integrates temperature and humidity sensing in one, no need to repeat installation. Install the temperature and humidity tags in different positions of the cold box/cold warehouse, the reader is installed in or outside the cold box, and the data collected by the temperature and humidity tags are uploaded in real time through the reader, so as to realize real-time in the background software system Monitor the temperature and humidity status in the warehouse, and prevent the abnormal change of the medicine caused by the abnormal temperature in the warehouse/cold box through the warning of the higher the temperature, the higher the humidity.
2. Macro
RF data stable transmission: add and flexibly design temperature and humidity probe lines or antenna extension cables; cold storage/cold car environment exploration: ordinary temperature and humidity tags, integrated high-power temperature and humidity tags, split high-power temperature and humidity tags, fully satisfied The needs of different environments; Label calibration: the national statutory calibration unit performs calibration to meet the strict monitoring requirements of the pharmaceutical industry for pharmaceutical logistics.
3. Micro feasibility analysis
1. Temperature and humidity label
Biswin 2.45GHZ temperature and humidity label, obtained by the authority, including the temperature and humidity calibration report certified by the National Bureau of Metrology;
RF remote real-time transmission, effective understanding of temperature and humidity alarms, grasp the dynamic law of temperature and humidity changes, remotely control various ventilation and temperature control equipment;
Advanced RF technology, the first domestic company to support remote change of the signal time, providing convenience for the equipment to save power;
Integrate temperature and humidity into one, simple and convenient;
Wireless power supply and transmission, greatly saving costs for project maintenance;
High precision.
2. WIFI interface reader
Features: Omni-directional antenna, capable of omni-directional identification and tracking of targets, stable and adjustable distance from 2 to 150 meters, 2.45GHz microwave band, universal ISM frequency band, reading 100 tags per second, and can manage 2000 in the field Labels.
3. Features of cold chain integrated machine:
Filtering: Through the filtering function, select the highest/lowest temperature and humidity point, or the average temperature and humidity value of a probe/multiple probes as valid information and upload it to filter the excess data.
Rule: Alarm setting, if the temperature and humidity are higher or lower than the set temperature and humidity area, the processing central control will automatically alarm.
Import: Import information data through the central control.
Save: You can set the number of saved information; save interval; choose real-time upload or upload data when you arrive at the destination.
Anti-lost mechanism: When the network is disconnected, the data sent by the tag in real time will still be saved, and the stored data can also be successfully uploaded when the network is available.
4. Operating platform
The platform service provided by BisWin includes three powerful functions:
(1) The operating platform is based on the purpose of convenience and low cost, built under the B/S architecture, and uses a high-speed cloud computing platform.
(2) Through the operating platform, users can understand the real-time monitoring of the temperature of transportation vehicles, cold storage, and thermostats in real time, and have a good grasp of the location of the vehicles on the road. Real-time data can be shared by various tripartite combinations of supervision departments, logistics companies, entrusting units; receiving companies, logistics companies, and drivers. The flexible design of order opening authority is more conducive to the openness and transparency of logistics and transportation information, and improves customer satisfaction and logistics company operation management.
(3) BisWin’s platform system is designed to facilitate the direct use of small and medium-sized logistics distribution and transportation companies after installing the equipment, without the need to invest huge funds and manpower to develop and maintain their own platform system. At the same time, there are also WMS platforms that are compatible with the mainstream market. Use real-time temperature and humidity monitoring systems faster, safer and more affordable.
Highlights of this application case:
Three modes of operation
1. Cold storage
Mainly through GPRS + temperature probe, the probe is fixed in the cold storage, and the temperature data is transmitted through the GPRS module fixed outside the cold storage. In response to abnormal heating or cooling, after the background monitoring and alarming, the staff quickly took measures to reduce the temperature or heating. So as to reduce or avoid losses. It is suitable for the environment that can receive GSM/GPRS network. Area: less than 500m2, temperature: 2-8 ℃; -20 ℃, material: insulation material, such as polyurethane, etc., storage: vaccines, injections and other special medicines.
2. Cold car
Put the reader in the cab, introduce the RF antenna into the cold compartment, put the temperature tag directly in the cold compartment, and find a suitable location to fix it. Through the reader, the temperature change in the cold car is transmitted to the temperature control center in real time. The control center is responsible for information exchange with intelligent vehicle terminals, classification, recording and forwarding of various short messages, network interconnection with other related functional departments, and the flow of business information between these departments; at the same time, it monitors and manages the entire network status . It is suitable for blood, vaccine fresh food, ice cream truck, frozen meat, distribution, etc.
3. Freezer
The temperature, humidity or temperature label is embedded or put into the refrigerator, and the label starts the recording function. When the label is out of the warehouse with the refrigerator, the label regularly records the temperature, humidity/temperature data. When the refrigerated box arrives at the delivery location, the recorded temperature, humidity/temperature data can be directly exported using the reading device, so that the temperature, humidity/temperature data during transportation can be seen clearly and intuitively for the acceptance of medicines/goods. It is suitable for the distribution of vaccines, fresh food, containers, etc.
