1. System overview
At present, the domestic paper industry is becoming more and more developed, and the problem of raw material management in paper mills is becoming more and more prominent. The raw materials or transit raw materials of the paper mill are generally stacked in a warehouse or a designated area. When stored for a long time, the temperature, temperature and humidity changes in the stacked raw materials, and the temperature rises too high and the humidity is too high and cannot be found in time. If it is treated together, it is likely to cause the deterioration of raw materials or semi-finished products, which will cause great losses to the paper mill. At present, domestic monitoring in this area is generally based on wired form, which is troublesome to install and wiring. Many cables are arranged on site, which is very inconvenient to use. However, with the development of RFID technology and sensing technology, wireless sensing Application has become a trend of industrial applications. We have put a lot of effort into this, and developed a set of temperature and humidity sensor-based raw material temperature and humidity monitoring system application solutions based on wireless RFID technology, which solved many problems that could not be solved before.
To this end, our company has launched a “2.4G long-distance radio frequency technology”RFIDThe paper mill’s raw material temperature and humidity monitoring and management system” solution. The system is safe and stable, easy to operate, and only needs to use the special temperature and humidity labels produced by the company and the corresponding card reader. At the same time, only a few The transmission line. Data transmission can be completed only by wireless.
2. System introduction
After adopting our RFID system, the method of uploading data by wireless transmission will be completely realized. This method greatly improves the shortcomings of the original wired method. It does not increase the original investment but also saves a lot of use and maintenance costs, making the granary Management has reached a new level.
1. System composition
The system mainly completes the functions of collecting, storing, and transmitting data to the monitoring center of the raw material temperature, humidity and gas concentration of the paper mill, as well as executing the instructions of the monitoring center. The system consists of the following parts:
The electronic tag inserted into the raw material pile: made by the 2.4G long-distance radio frequency card produced by Tangyuan Electronics. The radio frequency card is a temperature and humidity electronic label. This label is equipped with a temperature and humidity sensor. It collects the temperature and humidity in the warehouse into the label. The method of use is to insert it directly into the raw material.
Long-distance card reader: It is produced by Tangyuan Electronics, and its interface has RS232/RS485/RJ45 network interface. Installed in the warehouse (can provide wireless WI-FI, GPRS and other communication methods)
Temperature and humidity monitoring system software: the computer provided by the customer and the system-specific supporting software provided by the company. For the software part, customers can also design, and our company can provide relevant information.
2. The working principle of the system
First, put the temperature and humidity electronic tags produced by our company in the raw materials of the warehouse, and at the same time, install some electronic tags and card readers in the warehouse outside the raw materials, and confirm the connection of other lines to complete the installation of the system. During normal work, the label will collect the information of the warehouse raw materials, such as raw material temperature and humidity, warehouse temperature and humidity, etc., and send the information wirelessly, so that it can be received by a card reader installed nearby This information is transmitted to the system center, and then the information is transformed into intuitive information through the software of the system center, which is convenient for analysis and viewing, and at the same time provides the most favorable information basis for the next decision, thus realizing scientific automation Management.

Three, system characteristics
1. Excellent performance
Active identification card, high recognition reliability, 100% front-end recognition rate.
The active card recognition distance is long (10-50 meters), and the recognition distance is easily realized within 10 meters. Due to the actual situation of the warehouse, the card reading distance should not be too long. This solution does not require a handheld card reader to be placed next to the label, and can fully realize fully automatic identification.
Very high anti-collision performance (can recognize 300 active cards at the same time), high recognition stability (error rate is less than one hundred thousandths), truly achieve error-free, no missing cards, timeliness, and comprehensiveness. The system can be used Comprehensive and real-time monitoring of the internal temperature and humidity of the raw materials can promptly understand whether the temperature and humidity changes are abnormal, so as to take corresponding remedial measures in time. Improve management level, centralized management, distributed control; standardize the supervision and management of raw material storage, and improve the transparency and scientific nature of management.
2. High security and stability
High reliability: it can operate normally within the ambient temperature of -40℃-+85℃ (MTBF≥70000 hours), especially in the low temperature in the north and high temperature in the south, it has more advantages, and it can effectively resist the high dust in the air in harsh environments It can ensure the normal use of the equipment in environments such as humidity and humidity. High anti-interference, no special requirements for interference near the warehouse and perimeter environment, strong environmental adaptability, minimized device failure rate, reliable operation, ultra-low power consumption: long service life, low average cost, maintenance-free, and safe for humans , Healthy, no electromagnetic radiation pollution, safer to use. The working mode of the microwave module can be configured, and the transmission power can be adjusted.
3. System implementation benefits
Improve the information literacy and management level of employees, promote the scientific and intelligent storage of raw materials in our country, save storage management costs, timely handle raw material storage quality accidents, timely rescue raw materials, reduce quality accidents, and reduce economic losses.
Four, system function
The warehouse item supervision system can track and query the specific conditions of all items in the warehouse, including temperature and humidity, in real time.
Tracking: real-time tracking of temperature and humidity of a certain raw material product to ensure that the item is in the best environment
Inquiry: Inquire about the raw materials in the warehouse according to the needs, in order to understand the situation of the inquired part of the raw materials more clearly and directly, and facilitate management and decision-making
Modification: The basic system information of the stored raw materials can be modified. The modified information includes: the type of raw material, the name of the raw material, and the suitable temperature and humidity of the raw material.
