Jiangsu Tangan active 433MHz asset positioning and anti-theft alarm management
[ad_1]
Project background
At present, manual registration, barcode scanning, and UHF RFID technology are mainly used for asset management. Manual registration and barcode scanning technology still need to spend a lot of time to manage, while UHF RFID technology is due to the directivity requirements of the antenna and the human body. , The barrier characteristics of objects, and the high rate of missed reading hinders the application of this technology.
The active 433MHz asset positioning and anti-theft alarm management solution launched by Jiangsu Tangan can effectively overcome the shortcomings of UHF RFID technology, and can realize automatic and rapid material anti-theft management, warehouse management, inventory management, and location management. Wait.
Solution advantage
1. Multiple materials are allowed to enter or leave the warehouse in a parallel state at the same time, and some materials are allowed to enter the warehouse and some materials are out of the warehouse at the same time, without adding equipment.
2. The boundary of the excitation area is clear, the boundary error is about 30cm, and the signal excitation distance between the exciter and the electronic tag is adjustable from 2 to 7 meters.
3. The electronic tag is usually in the standby state, and only emits signals when it enters the excitation area and is excited. It has the characteristics of health and environmental protection, ultra-low power consumption, no radiation damage, and safe and reliable use.
4. 433MHz activeRFIDThe technology has the characteristics of strong penetration, strong diffraction, long transmission distance, etc., suitable for various complex environments, and the system is stable and reliable.
5. The system automatically counts materials in real time. When the quantity of materials is abnormal, the system immediately alarms.
6. The electronic tag adopts special anti-dismantling technology, and the action of the anti-dismantling switch is both sensitive and accurate. As long as there is an attempt to remove the label, the label will emit an alarm signal and the system will alarm immediately.
7. Real-time monitoring solves the problem of unrecognized carry-out violations of the general entry and exit system (such as illegal carry-out from windows, etc.). As long as the materials leave the designated area for more than the system set time, the system will immediately alarm.
8. High reliability, the hardware is industrial grade product, and the system works 24H uninterrupted and reliably.
Scheme principle
The system consists of “monitoring computer”, “RFID reader”, “RFID exciter” and “RFID electronic tag (hereinafter referred to as electronic tag)”.
1. Installation plan:
1. Paste the electronic label on the items that need to be monitored to realize one item, one card.
2. Install excitation antennas on the inner and outer sides of the warehouse gate in the direction of entry and exit, and the excitation antenna is connected to the exciter.
3. Install a certain number of excitation antennas in the material range of the warehouse to be monitored and connected with the exciter to realize the full range of excitation signal coverage of the monitored materials.
4. The warehouse duty room allocates management computers and installs management system software.
2. Working principle:
When items with electronic tags enter the inner antenna or outer antenna excitation area of the RFID exciter at the warehouse gate, the electronic tag is awakened and sends a 433MHz radio frequency signal to the outside. The “RFID reader” obtains the electronic tag signal and transmits the information to the monitoring system. Computer, the monitoring computer automatically judges and records the entry and exit status of items according to the wake-up sequence of the electronic tag being excited by the antenna inside or outside the gate.
For items in the library, the exciter wakes up the electronic tags in the excitation area according to the established time intervals and rules. After the electronic tags are awakened, they send out corresponding 433MHz radio frequency signals with 125KHz excitation location information, and the “RFID reader” obtains the electronic tags. The signal and information are transmitted to the monitoring computer, which can determine the object and its location based on the ID of the electronic tag and the location information of the excitation. If a certain electronic label information is not received, it means that the electronic label is no longer in the incentive area of the warehouse.
likeelectronic labelAfter being disassembled, the electronic tag immediately sends a 433MHz radio frequency signal with disassembly information, and the system will determine whether to issue an alarm based on its legitimacy.
System functions
1. Automatic warehousing management
2. Location monitoring: real-time display of the location of items in the library
3. Anti-theft alarm: start the anti-theft alarm when the item is illegally out of position
4. Anti-dismantling alarm: If the label is disassembled, it will alarm immediately
5. Software shutdown password: you need to enter the password to close the software
6. Cancel the alarm password: you need to enter the password to cancel the alarm
