The fourth generation cold chain monitoring system GPS , GPRS technology application
The application of GPS real-time, all-weather, continuous, fast and high-precision features to the cold chain monitoring industry will bring about a substantial change, and will play an increasingly important role in the development of the cold chain monitoring industry. From hardware design to software development, the fourth-generation cold chain monitoring system has been officially launched. The application of GPS technology in cold chain logistics greatly improves the quality of transportation and effectively guarantees the transportation time, thus ensuring the quality and timely arrival of cold chain products. The fourth generation of cold chain monitoring system integrates temperature monitoring technology and GPS technology organically, and implements all-round monitoring and management of transportation operations, which not only improves the accuracy of information in transportation, but also realizes real-time automation of transportation management. . Thereby ensuring the quality and timely arrival of cold chain products, will play an increasingly important role in the development of the cold chain monitoring industry and logistics industry.
First, the feasibility of using GPS technology in cold chain logistics transportation
(1) Technical feasibility. The GPRS technology adopts a packet switching technology, and each user can occupy multiple wireless channels at the same time, and the same wireless channel can be shared by multiple users, so that resources are effectively utilized. GPRS technology is very popular with its 160kbps transmission. It uses GPRS data to realize packet transmission and reception. Users are always online and charge according to traffic and time, which quickly reduces service costs. Therefore, it is feasible to use GPRS technology to complete the real-time transmission of information in cold chain logistics.
(2) Economic feasibility. Although the GPRS service remains online all the time, there is no need to worry about the cost, because it is only billed when traffic is generated. At present, GPRS can support a peak transmission rate of 56 Kbps, and the theoretical peak transmission can reach 114 Kbps. At this stage, GPRS technology can collect information for the vehicle every 5 seconds, and the cost per month is only 5 yuan. This cost is widely accepted compared with the profit brought by GPRS technology.
(3) Management feasibility. At this stage, the cold chain logistics industry market is becoming more and more standardized, the quality of employees is getting higher and higher, and the theory of cold chain logistics management is becoming more and more understood. With the widespread recognition and application of GPS technology and RFID, GPRS, and GIS technologies, its management is becoming more and more standardized.
Second, the application of GPS and GPRS technology in cold chain logistics
Since cold chain products must be stored and transported at low temperatures, if there is an accident such as vehicle anchoring or freezing system in transportation, the quality of the cold chain products will be greatly affected. Therefore, GPS positioning technology is applied to the cold chain logistics to realize resources through the network. Sharing, monitoring the running route of the vehicle during the transportation of the cargo, the real-time running position of the cargo, the safety of the personnel, the operation of the vehicle and the temperature inside the cabin, real-time and accurate grasp, facilitate the command and dispatch of the vehicle, once it occurs Accidents and quick decisions.
The application of GPS in cold chain logistics includes:
(1) Vehicle tracking. Through GPS technology, real-time tracking display of selected vehicles can be realized, and the results of positioning are represented by GIS geographic information system, which directly reflects the position of the vehicle, the road condition, the distance from the nearest cold storage, and the distance between the running lines of the vehicle. As shown below:
(2) Operation monitoring. A temperature sensor is installed in the refrigerator. The temperature collected by the temperature sensor is transmitted back to the monitoring center in real time through the in-vehicle device. Vehicles can transport products of different temperature ranges according to actual needs during transportation. For example, plasma products are shipped at temperatures ranging from -15 to -25 degrees, and blood products and vaccines are in the range of 2 to 8 degrees. The system uses the corresponding temperature range standard as the basis for temperature monitoring according to the driver's choice of transportation type. According to the comparison of the temperature, it is judged whether the temperature meets the specified range. If the temperature exceeds the set range, the system will promptly send the driver to the temperature, such as voice, SMS, telephone, etc., to remind the driver to deal with it in time to ensure the quality and safety of the product during transportation. The monitoring process is as follows:
The fourth generation cold chain monitoring system realizes the refined management of cold chain transportation through GPS satellite positioning technology and GPRS mobile communication transmission technology, and provides more abundant personalized solutions and technical means in the information management mode. Continuously creating customer satisfaction is our goal!
