Description

 Solar powered fixed automatic reader based on wireless network technology

 The present invention relates to a stationary reader, and more particularly to a solar powered fixed automatic reader based on wireless network technology.

Background technique

 With the in-depth development of RFID technology and the wide application of RFID technology. At present, the use of (RFID) electronic labeling in the (port) container transport chain to monitor container transportation, to ensure the safety of long-distance container transportation and to improve the transparency of the container transportation chain has become the focus of attention of many people in the port and shipping industry. Therefore, RFID and Related products have also started research on ports.

 The electronic tags and their readers currently used for container transportation are used together, that is, a manufacturer that produces both electronic tags and readers that talk to them. However, the fixed readers already on the market rarely meet the requirements of complex environments including ports.

 First, when using RFID technology for container monitoring on the container transportation chain, fixed readers installed at the packing point, crossing (and yard), and bridge cranes need to have access to the internal wired or wireless network in the port area. The information written into and read from the electronic tag is transmitted to the upper computer of the electronic tag system, and the complicated environment of the port area determines that the port cannot install the network freely within the port area and pull the network cable.

 Secondly, the fixed reader used in the monitoring area is used for data transmission in complex environments. The power supply at the installation point is a difficult point (long use time, difficult maintenance and repair, and inconvenient replacement of equipment). Therefore, fixed automatic The reader needs to have its own power supply,

Confirmation And for sustainable power supply, this avoids the wire draw-out of the (dock area) monitoring point, ensuring the normal operation of the fixed reader (life).

 Finally, the monitoring points and the port area are generally located in remote areas of the city. The network signal coverage is incomplete and unstable. Therefore, the fixed reader is required to have the function of automatically storing information, so that the system can transmit the signal in time when the signal is good. It can be saved when it is not good, and it will not be lost.

Summary of the invention

 The invention is directed to the shortage problem of the current fixed reader, and proposes a solar power-based fixed automatic reader based on the wireless network technology, which can use the solar power to ensure the use of the wireless automatic network transmission mode fixed automatic reader, The wire pull-out condition of the monitoring point is avoided, and the continuous normal operation of the fixed reader is ensured.

 The technical solution of the invention is: a solar power-based fixed automatic reader based on wireless network technology, comprising a GPS positioning chip, a microprocessor, a radio frequency communication module, a radio frequency communication module collecting tag information, and a GPS positioning chip for determining position information The data information of the radio frequency communication module and the GPS positioning chip is transmitted to the microprocessor, and further includes a wireless communication module, an information automatic storage module, a solar power source, and the microprocessor data information is saved to the information automatic storage module, and then the wireless communication module is used. The wireless transmission mode is transmitted to the upper computer of the electronic label system. The fixed automatic reader is powered by the solar power source. All the modules are integrated into one whole, fixed in a box jacket, installed at the entrance and exit of the container or at the port area. .

The wireless communication module is one of GPRS, CDMA, WIFI or 3G modes. The solar power source is a battery windsurfing board or a solar energy battery. Automatic storage of the information The module stores the microprocessor data information in real time. The invention has the beneficial effects of: 'The invention integrates the wireless communication module, avoids the problem of pulling wires and network cables inside the port area; integrates the solar battery, and solves the problem that the fixed reader cannot be continuous Power supply, need to replace the battery, enable the fixed reader to achieve continuous operation, continuously transfer the time and location of the container door opening/closing, container logistics information and safety information, ensuring real-time reading of node data in container transportation monitoring Sex, accuracy and safety have effectively improved the transparency and safety of container transportation and met the anti-terrorism and anti-terrorism requirements of container transportation.
