system introduction
The system applies RFID to the cold chain transportation monitoring system, and installs monitoring equipment on the transportation vehicle. The monitoring equipment consists of a 2.4G RFID wireless receiver, GPS global positioning device and GPRS wireless data transmission. It is on each box of items or individual packaging. Equipped with a temperature tag, the temperature tag can test the current temperature in real time, and use 2.4G wireless data transmission to the monitoring device. The monitoring device wirelessly sends the temperature of the item and the current vehicle position to the back-end data monitoring center via GPRS.

Operating mode
The working mode of the reader is “passive or active”. In general applications, the reader is in the receiving state, receiving the signal from the “active” active electronic tag in real time, and forwarding the received data to the background management system . In special applications, you can also write data to tags or change parameters.
Recognition distance
The reader is matched with the company’s “active” active electronic tags. In a good visual environment, the maximum recognition distance can reach a radius of 100 meters. Compared with passive tags in specific applications, the super-strong signal and super-long recognition distance have great advantages.
When the user has different requirements for the recognition distance or the application environment is more complicated, active electronic tags and readers with different signal strengths can be selected, and the gain of the reader can be adjusted by software to achieve the required recognition distance.
Recognition speed & ability
When the active electronic tag runs at a maximum speed of 200Km/h within the effective identification range of the reader, stable identification can be ensured. This feature can completely guarantee the identification of people and objects in high and low speed motions.
The reader can read more than 500 active electronic tags at the same time, and the recognition accuracy rate is 99.999%; it can ensure that all identifications are not missed in a very short time. This feature is particularly suitable for personnel management in schools, super large enterprises and institutions, as well as a large number of asset monitoring positioning and warehouse management applications.
Communication security
When the reader and the supporting active electronic tag communicate, a special communication protocol is used to verify the legitimacy of the device, and a complete encryption algorithm has been developed to prevent data cracking to ensure data security in the communication process.
Reliable work
The product fully considers the application requirements of industrial environment such as lightning protection, waterproofing, and impact protection; the production process is strictly controlled in accordance with the ISO9001 quality standard for multi-step process control to fully ensure product performance and quality.
Interface standard
The reader can provide standard hardware interfaces such as RS485 weigand26 RJ45 TTL. If you need an interface such as RS232 or WiFi, please specify when ordering.
The company provides standard software interfaces in line with the Windos series operating system platform and provides the underlying communication protocol.

Operating mode
The tag adopts “active or passive mode” to work, the tag actively emits a signal or emits a signal after being triggered by the instruction of the reader. The frequency of emission and temperature measurement is adjustable.
The tag detects the ambient temperature according to the predetermined frequency or the instructions of the reader and transmits ID and temperature information to the reader. When the temperature exceeds the set upper and lower limits, it can be alerted by the built-in buzzer.
Recognition distance
This “active” positioning electronic tag can work with many of the company’s readers. In specific applications, the signal strength and recognition distance have very prominent characteristics. In a good visual environment, the recognition distance can stably reach 100 meters.
When users have different requirements for the length of the maximum recognition distance, or the application environment is more complex, you can choose to use different signal strength readers, and the sensitivity of the reader can be adjusted through the application software to achieve the required recognition distance.
Recognition speed & ability
Within the effective recognition range of the reader, the temperature measurement interval can be adjusted wirelessly; the function of wirelessly calibrating the temperature reference value can be provided on demand.
The storage capacity of the read-write type temperature tag can reach up to 16Mbit, which can be used for real-time test and upload; and offline test the ambient temperature (temperature record value can reach 500,000), after reaching the destination, the record value can be analyzed by the reader These two applications.
Communication security
When the active electronic tag communicates with the supporting reader, a special communication protocol is used to verify the legitimacy of the device, and a meticulous encryption algorithm has been developed to prevent data cracking to ensure data security during the communication process.
Reliable work
The product fully considers the application requirements of industrial environment such as lightning protection, waterproofing and impact protection; the production process is strictly in accordance with the ISO9001 quality standard for multi-step quality inspection
