Description

Technical Field

[0001] The invention belongs to the technical field of passenger supervision services, and specifically refers to a safety buckle status monitoring system based on RFID technology. Background Art

[0002] According to the Civil Aviation Law of the People's Republic of China and the relevant regulations of the Civil Aviation Administration of China, passengers are required to fasten their seat belts during the flight, but in reality there are many passengers who violate the relevant regulations. According to the manual counting method of the Regulations on Passenger Service Management for Public Air Transport, the current method is mostly completed by the crew counting one by one. This step occurs in the pre-takeoff preparation stage, which takes up a lot of crew time and energy, and also occupies precious airway aviation resources. And because the supervision and management of the crew is limited, it is not ruled out that passengers will dismantle their seat belts by themselves after the count. In addition to the above-mentioned manual counting method, the prior art also proposes a machine vision recognition and counting method for human portraits, but the machine vision recognition and counting method using human portraits has low accuracy, extremely high configuration cost, high requirements for the operating environment such as electricity, poor stability, and high maintenance cost, and cannot meet the existing civil aviation requirements.

[0003] With the popularization of the concept of the Internet of Things (IoT), UHF RFID (Ultra-High Frequency Radio Frequency Identification), as one of the important IoT technologies, has been further widely used and technically optimized. In recent years, the application of UHF RFID in the fields of smart manufacturing, asset management, medical health, smart cities, etc. has continued to expand. In terms of technology, UHF RFID has been continuously improved in terms of the performance, reading distance, and anti-interference ability of tags and readers, and the application scenarios have become more diversified and complex. With the further advancement of technology and the continuous growth of application demand, UHF RFID will play an important role in more fields.

[0004] In summary, relying on the vigorous development of the aviation industry, the installation conditions of electrical equipment in aircraft cabins have been gradually improved, and the technology of safety facilities has become more mature. However, according to the requirements of civil aviation, the counting of passengers has always been difficult to be replaced by machines, and manual counting consumes a lot of crew time and aviation resources. Relying on the reliability and stability of RFID technology, we have conceived a safety buckle status monitoring system based on RFID technology. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a safety buckle status monitoring system based on RFID technology, which is used to solve the problems of time-consuming manual counting, limited supervision, low machine vision recognition accuracy, high cost and unstable operation.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] Passenger monitoring unit; the passenger monitoring unit is used to detect the status of the seat belt facilities and determine whether the passenger fastens the seat belt during the flight;

[0024] Crew monitoring unit; the crew monitoring unit is used to issue instructions and to detect whether the behavior of the passenger monitoring unit conflicts with the instructions. If there is a conflict, the crew will be notified for on-site control.

[0025] refer to Figure 1 and Figure 2 As shown, the passenger monitoring unit includes an inductive locking device, which includes a lock body 1 and a tongue 2 connected to the free end of the seat belt, an RFID tag is provided at a front section (A) on one side of the tongue 2, and two groups of paddles are hingedly provided on the lock body 1 toward the outside of one side of the tongue 2, and the tongue 2 and the RFID tag in an open circuit state are embedded between the two groups of paddles to achieve passage.

[0026] The paddle and the inner wall of the lock body 1 are provided with springs for limiting, a lock track is provided between the two groups of paddles, an open section B is provided inside the lock track, and an RFID tag in an open state is embedded in the open section of the lock track. The open section is the only disconnection point of the RFID tag, and a passage is achieved if it is closed. The metal front section of the plug tongue 2 is made of conductive material, the rear section of the plug tongue 2 is widened, the plug tongue 2 is inserted into the lock track, the paddle and the plug tongue 2 are interlocked and locked, and the end of the plug tongue 2 is locked in the lock track, and the two sections of the open section are connected to the paddle and the spring, and the paddle and the spring are both made of conductive material. When the plug tongue 2 enters the lock track, the plug tongue 2, the paddle, the spring and the open section form a passage RFID element.

[0027] refer to Figure 3 As shown, the crew monitoring unit includes an ultra-high frequency RFID reading system for reading the information of the RFID tag. In conjunction with the ultra-high frequency RFID reading system reading segment and component pre-written information, the system can realize passenger status monitoring, abnormal movement warning and cabin safety analysis during flight.

[0028] When the inserting tongue 2 is inserted into the lock path, the RFID tag forms a passage, the two parts of the safety belt are in a closed state, and the UHF RFID reading system reads the RFID tag as a normal state;

[0029] When the inserting tongue 2 is separated from the lock track, the RFID tag is disconnected, the two parts of the safety belt are in a separated state, and the UHF RFID reading system reads that the RFID tag is in an abnormal state.

[0030] Example 2

[0031] At the component end, considering the integrity damage caused by component wear, the connection problem between the various conductive systems of the seat belt lock body, the degradation of conductivity caused by environmental factors such as oxidation, and other unknown and uncontrollable factors, the component path breaking method can be changed to "place a striker or elastic button in the seat belt base" to trigger, or introduce a micro switch trigger in the seat belt base. At the same time, considering the radio frequency distance and civil aviation requirements, the RFID component segment can be changed to active.

[0032] On the reading device side, taking into account the radio frequency distance and civil aviation requirements, it can be changed to a handheld receiving terminal during actual implementation.

[0033] In addition, the core ideas and principles of this patent can be applied to the polarization of states such as "switch closure" and "two-state change", such as observing the closure of a switch, whether the environmental state exceeds a certain threshold, the on and off of a circuit, etc. The perception of state changes can also be assisted by sensors, which can be used to monitor environmental changes, the presence of light, water and electricity, and other purposes.

[0034] It should be noted that although the embodiments of the present invention have been shown and described, for ordinary technicians in this field, without departing from the purpose of the invention, structural methods and embodiments similar to the technical solution are designed without creativity and should all fall within the scope of protection of the present invention.
