A: solar street lamp controller recovery voltage
We often encounter a customer response, my lamp is normal light a few days before, a few days after the rain, can not work properly, check the normal solar controller indicator, the battery also has 12V voltage, lamp source also bright which directly connected to the battery, what is the problem, replace a controller,then good. Here to understand the solar charging controller has a recovery voltage, the general controller recovery voltage point is 12.5V, only when the battery voltage exceeds the voltage point, the solar street lights can automatically reply

DP is the largest mail service operator in Europe. The company has international mail, lightweight goods express delivery business, last year revenues of 1 billion euros. All DP's international courier services pass through the Frankfurt sorting center. Deutsche Post uses RFID technology to track international mail.
RFID is not new to the postal industry. Like other IPC members, DP installed UHF RFID readers at key facilities to make it easier to monitor the quality of international mail services. In addition, DP installed an passive RFID tag reader at the International Mail Terminal to monitor and improve processes.
 

UHF RFID can simultaneously read both near-field and far-field RFID labels. Due to the diversity applications, an UHF RFID reader can more efficiently satisfy read requirements in many operating environments. For example, in large parking lots, such as small and medium-sized trucks, trucks, staff and visitor vehicles, etc., their security access control systems must consider the requirements and restrictions of all vehicles. UHF RFID has the advantages of far-field reading, to meet the needs of different high and low reading position, for example, patrol large range applications (such as university campuses or large hospitals), the long range UHF RFID reader mounted on the patrol car, patrol officers sitting in the car and directly read and verify the electronic tag data.

RFID room automatic guidance system contains remote RFID reader at where it need to place the guide, when the person passing through the card is automatically identified at long-distance (the card can be put anywhere on the player). And system shows the cardholder the location of the room and the electronic map animation guide. The system can also be extended, such as access control, VIP, multimedia player and other functions.

The application of RFID technology in production management helps manufacturers to monitor the operation of production line equipment components and manage the products in and out of warehouses, and manage the warehousing of distribution centers.
Due to the non-visual reading of RFID technology and the multiple labels reading, multiple RFID reader read all of its logistics data at one time and accurately, which greatly enhanced the efficiency of process management in the supply chain of manufacturing enterprises.
Supply process management: System contains procurement control, order matching, supply cycle control, quality tracking, commissioning process control, in-transit cargo tracking.
Production process management: The key part of whole production, with material cost control, production statistics, pieces of statistics. According to user needs, solution with Ethernet RFID reader and labels can also achieve the production line equipment operation monitoring and management.
Logistics Management: Order product distribution, multi-library collaborative operations, storage warehouse, issuing operations, in and out of stock alarm, unsalable product statistics etc.
 

According to our customers' feedback from years, the first time using RFID reader device, they often encounter some common problems. In fact, the solution is very simple, but many people have not used the device, do not know how to rule out the reason. Today let’s carefully finishing a few of the most common problems and the corresponding solutions for your reference.
1, Interference between multiple readers
When there are two or more readers working at the same time, in order to do not interfere with each other, reader installation and debugging ensure that the following requirements:
(1) The distance between two readers is more than 3 meters
(2) The operating frequency of two adjacent readers are set to 920MHz-925MHz frequency hopping, reading time interval should be staggered.
2, Short reading distance
Commonly UHF long range RFID reader could at least read 5-20 meters distance, some setting must be wrong if it could not reach the range.
(1) Check the reader frequency settings are correct. Working mode should choose frequency hopping, frequency hopping range 920MHz - 925MHz.
(2) Check label and antenna polarization direction match.
(3) Check label surface is covered with other materials like metal.
(4) Check the RFID label's properties.
(5) Check the RF cable connected to reader and antenna.
3, Can not read card
(1) Whether the serial cable or the network cable is properly connected, if the cable is not connected or the connection is not secure, the PC command can not be sent to the reader.
(2) Check whether the RFID antenna SMA connector is tightened and the label is damaged.
(3) Check if the label complies with the ISO18000-6B / C protocol.

In the early morning of November 10, the official ball of the 2018 World Cup in Russia was created with brand new technology. Called the "Telstar 18" (TV star), the football is printed on a gold-colored Russian World Cup Logo with a gradient mosaic pattern and a built-in NFC chip. Using many new technologies and innovative NFC chips, you can transfer data with your smart phone. Each ball generates a unique identifier that allows the user to unlock exclusive data messages. So what is NFC and what is the difference between RFID and RF technology?
RFID is a contactless identification technology, divided into two kinds, active and passive. The main working principle is that the RFID tag reader emits radio frequency signals through the coil of the electronic tag, and the reader reads and decodes the information to complete the entire identification process.
It automatically identifies the target object through radio frequency signals and obtains the relevant data. The identification work needs no human intervention and can work in various harsh environments. Long range RFID technology can identify high-speed moving objects and can simultaneously identify multiple labels, and the operation is quick and easy.
In recent years, NFC is a technology applied more on mobile phones, the mainly functions between two NFC devices is mutually interacts information and completes corresponding transactions when they are at a relatively close distance. NFC's biggest feature is the integration of readers and transponders in the same chip. It meets and simplifies information exchange, content access, service exchange between any two wireless devices.
 

With the development of society and the constant construction of cities, various office buildings, commercial buildings and residential buildings have mushroomed and become the rulers of social development. However, the management, maintenance, repair problems always let the user complain a lot, or even frequently negative feedback.
So how to deal with the huge group of buildings security, management, maintenance, repair, fire fighting problems? We provides a one-stop solution With RFID handheld terminals.
 

With the improvement of the overall national quality, The phenomenon of littering has been gradually reduced in the city. This is also reflected that the gradual improvement of garbage disposal in China.Many years ago the environmental protection department began to use RFID technology of trash can .But it isn’t universal to all regions of the country.
At present, Some areas have begun to use this technology or other technologies of Internet of things. But relatively speaking, RFID technology compared to other technologies in this application is still relatively mature, and have a big advantage over.

Does the medical industry need RFID technology? The answer is yes. The fact that newborn infants are often characterized by similarities and are indistinguishable and lack their own ability to understand and express themselves and, if not effectively identified, often cause misidentification to be replaced. For the newborn baby, RFID tag associated with maternal and child, that is, the newborn babies and their mothers for the both sides associated with the logo, the same coding and other means to link the natural mother and child.
 
At all important entrances and exits installed long distance RFID reader, each time nurses and babies need to pass by reading the nurse's RFID identification card and the baby's RFID baby identification tape, the identity of the identity can be passed, Otherwise, the system will send an alarm to prevent the baby from being stolen. During the hospital, mother and child must wear the label.
