1. TS005 (Items can be moved within the supervision area, as long as they do not leave, it is safe)
* Basic description
This solution uses 2.4G radio frequency identification technology to meet the requirements. The specific implementation process is as follows:
1. First, configure labels for supervised goods, so that each product is bound with a label. If it is a metal product, you need to pay attention to the installation method of the label, and the label should be at least 2 cm away from the metal surface;
2. Secondly, place 2.4G readers in the controlled area, and achieve full coverage of 2.4G signals with consideration of occlusion;
3. The tag periodically sends the ID code, and the reader receives the binding label information, indicating that the goods are safe. If the tag ID of a certain bound goods is not received within a certain period of time, an early warning will be issued and manual confirmation is required for the existence of the goods Security risk, or label failure.
* system structure
* basic skills
1. The reader can use directional or omnidirectional antennas as required to achieve 2.4G signal coverage, and the range can be set;
2. After the 2.4G reader receives the tag ID, it uploads to the system via RS485/RJ45, and the system compares the information. If there is a discrepancy between the uploaded information and the preset information, it will immediately alarm;
3. The reader has two working modes: active upload and receiving command upload;
4. The processing speed of the system is fast, and the safety warning response is no more than 3 seconds.
* System advantages
1. The 2.4G signal can easily achieve full coverage;
2. The 2.4G air transmission rate is high, realizing a large number of concurrent, large-scale data interactions;
3. The system equipment is simple in structure and convenient to implement;
4. Convenient area coverage control and adjustment;
5. The system responds quickly.

2. TS006 (Items can be moved in the supervision authorized area, and taken to the non-authorized area to alarm)
* Basic description
This solution uses 2.4G radio frequency identification and low-frequency trigger technology to meet the requirements. The specific implementation process is as follows:
1. First, configure low-frequency trigger tags for supervised goods, so that each product is bound to a label. If it is a metal product, you need to pay attention to the installation method of the label, and the label should be at least 2 cm away from the metal surface;
2. Secondly, place 2.4G readers in the controlled area, and achieve full coverage of 2.4G signals with consideration of occlusion;
3. Place the landmark device in the controlled area. Once the goods arrive in this area, the system will give an early warning, or the reader will give an early warning directly. Generally, landmarks are placed in the access passages of the controlled area, and goods are not allowed to move to this area without authorization;
4. The tag periodically sends the ID code, and the reader receives the binding label information to indicate that the goods are safe. If the tag ID of a certain bound goods is not received within a certain period of time, an early warning will be issued and manual confirmation is required for the existence of the goods Security risk, or label failure.
* system structure
* basic skills
1. The reader can use directional or omnidirectional antennas as required to achieve 2.4G signal coverage, and the range can be set;
2. The area covered by the landmark is an approximate circle, with an adjustable radius of 2-4 meters as required, and is generally placed in important control channels;
3. After the 2.4G reader receives the tag ID, it uploads to the system via RS485/RJ45, and the system compares the information. If there is a discrepancy between the uploaded information and the preset information, it will immediately alarm;
4. The reader has two working modes: active upload and receiving command upload;
5. The processing speed of the system is fast, and the safety warning response is no more than 3 seconds.
* System advantages
1. The 2.4G signal can easily achieve full coverage;
2. The 2.4G air transmission rate is high, realizing a large number of concurrent, large-scale data interactions;
3. The area covered by the landmark device has a clear boundary with an error of 30 cm, which clearly defines whether the goods bound label arrives in this area;
4. The system equipment is simple in structure and convenient to implement;
5. Convenient area coverage control and adjustment;
6. The system responds quickly.

3. TS007 (Items cannot be moved in the supervision area, and they will alarm when they are moved)
* Basic description
This solution uses 2.4G radio frequency identification and vibration sensor technology to meet the requirements. The specific implementation process is as follows:
1. First, configure labels for supervised goods, so that each product is bound with a label. If it is a metal product, you need to pay attention to the installation method of the label, and the label should be at least 2 cm away from the metal surface;
2. Secondly, place 2.4G readers in the controlled area, and achieve full coverage of 2.4G signals with consideration of occlusion;
3. The tag has a built-in acceleration sensor. If the tag moves, the corresponding flag is valid, and the system is uploaded through the reader to immediately give an early warning. The vibration threshold can be set according to requirements.
