Abstract
Description
Technical Field
[0001] This application relates to the field of data acquisition technology, specifically to a wireless information receiving device based on radio frequency identification (RFID) technology. Background Technology
[0002] Data setting is a key step in configuring information for a missile guidance system. Its core purpose is to transmit data such as target parameters and flight procedures to the onboard computer via wireless or wired means.
[0003] Early missile technology was relatively simple, and data setting was mainly carried out in a primitive way, such as manually setting parameters and using simple electromechanical devices for data input. The data setting efficiency of missiles in this period was low, the accuracy was limited, and the types of data set were limited, mainly some basic flight parameters, such as range and angle of attack.
[0004] With the development of missile technology, wired data setting methods have emerged. These methods connect ground control equipment to the missile's electronic systems via cables or other physical connections, enabling data transmission and setting. This improves the stability and accuracy of data transmission and allows for the setting of more diverse data, such as guidance parameters and target information, thereby enhancing the missile's accuracy and combat effectiveness. However, wired data setting methods suffer from drawbacks such as poor flexibility and long launch preparation times, limiting the missile's rapid response capabilities.
[0005] To overcome the shortcomings of wired setting, wireless data setting technology emerged. Early wireless setting was based on the principle of coil electromagnetic induction. During setting, coupling coils were placed on the setting head and the ammunition respectively. When the setting head generated an alternating magnetic field, the induction coil on the ammunition generated an induced electromotive force and current, thereby realizing data transmission. This technology eliminates the need for physical cable connections, reducing equipment complexity and weight. Moreover, because electromagnetic energy is mainly transmitted in the near-field induction field, it has strong anti-interference capabilities. For example, the muzzle induction setting technology of the Swiss twin 35mm anti-aircraft gun accurately sets the fuse at the base of the projectile through electromagnetic induction before the projectile leaves the muzzle, and accurately detonates the explosive based on the setting time, effectively attacking aerial targets. However, coil induction setting also has limitations in communication distance, usually requiring the setting head to be very close to the ammunition, generally within a few centimeters. In addition, the data transmission rate is relatively low, making it unsuitable for scenarios involving rapid setting of large amounts of data.
[0006] In modern warfare, the demands for rapid response and multi-target engagement capabilities have led to the widespread application of radio frequency (RF) setting technology. RF setting utilizes radio frequency identification (RFID) technology to achieve contactless data transmission via radio frequency signals. RF signals can transmit data over relatively long distances, typically from a few centimeters to tens of centimeters, with high data transmission rates, enabling the rapid setting of large amounts of data. This significantly improves launch preparation efficiency and flexibility. With technological advancements, improved RF setting technologies have emerged, such as those employing spread spectrum communication and frequency hopping communication, enhancing the anti-interference capabilities and security of RF setting.
[0007] To meet the application requirements of omnidirectional radio frequency positioning for missiles, the receiving device must be able to conduct wireless communication without blind spots within a 360° range along the missile's axis. This necessitates a systematic solution to the following technical challenges.
[0008] 1. Antenna Radiation Pattern Issue: Traditional directional or conventional antennas struggle to meet omnidirectional coverage requirements, necessitating the development of novel antenna structures with omnidirectional radiation patterns. This ensures uniform reception of radio frequency signals at any azimuth angle along the axis of the antenna.
[0009] 2. Receiver size and installation issues: Due to space constraints within the missile body, the receiver needs to be miniaturized to ensure that its size and weight are reduced as much as possible while meeting performance requirements. Utility Model Content
[0010] The purpose of this application is to provide a wireless information receiving device based on radio frequency identification technology, which can be well structurally formed with the projectile body, ensuring not only the integrity of the projectile body's shape but also achieving reliable antenna performance.
[0011] To achieve the above objectives, this application provides the following technical solution:
[0012] This application provides a wireless information receiving device based on radio frequency identification (RFID) technology, including a housing, a microstrip antenna attached to the housing, an antenna matching component disposed outside the microstrip antenna, an antenna radome disposed outside the antenna matching component, the antenna matching component making the antenna radome conform to the housing, an amplitude and phase adjustment plate connected to the microstrip antenna installed inside the housing, and the amplitude and phase adjustment plate then transmits radio frequency signals to an energy management board and a signal processing board respectively through an RFID connector.
[0013] The microstrip antenna consists of two pieces, which are conformally bonded to the housing.
[0014] The housing and the radome are sealed with glue.
[0015] The amplitude and phase adjustment plate is fixed inside the housing by a combination screw, and the radio frequency signal received by the microstrip antenna is transmitted to the amplitude and phase adjustment plate through a coaxial feed pin.
[0016] The energy management board converts radio frequency signal energy into electrical energy to power the signal processing board. The signal processing board is responsible for demodulating the radio frequency signal, and the demodulated data is sent to the onboard computer via a wired connection to realize the radio frequency data setting function.
[0017] Compared with the prior art, the beneficial effects of the present invention are:
[0018] 1. Improved setting efficiency: The receiving device based on radio frequency identification (RFID) technology is suitable for missile data setting. This patented technology uses wireless radio frequency communication technology, eliminating the need for communication cables and other facilities required for wired setting. This significantly reduces the workload of launch preparation, greatly shortens launch preparation time, and enables rapid data setting, greatly improving launch efficiency and better meeting the requirements of rapid launch in modern warfare.
[0019] 2. Enhanced flexibility and adaptability: Radio frequency (RF) calibration is free from the constraints of cables, and its transmission power is adjustable, allowing it to be adjusted according to different calibration distance requirements. It can be flexibly applied in different environments and scenarios, overcoming the shortcomings of traditional coil induction calibration which has too short a distance, and also solving the problem of wired calibration technology being limited by the calibration site.
[0020] 3. Improve communication reliability: Radio frequency devices can encrypt communication data through top-level protocols, and both the sender and receiver use verification algorithms to ensure communication reliability, effectively avoiding interference from external data or other interference data.
[0021] 4. Enhanced anti-interference capability: Through technologies such as spread spectrum communication, mutual interference between communication channels is reduced, and anti-interference capability is improved, enabling radio frequency devices to transmit data stably even in complex electromagnetic environments.

[0033] To achieve omnidirectional performance and obtain omnidirectional beam coverage, a conformal microstrip antenna array design was adopted. Microstrip antennas are characterized by their simple structure, low profile, and ease of bending, allowing for better structural integration with the projectile body. This not only ensures the integrity of the projectile's shape but also achieves reliable antenna performance. By adjusting the antenna design parameters, the antenna achieves omnidirectional radiation along the projectile's axis in 360°, with undulations meeting the required specifications.
[0034] To address the miniaturization issue of the receiving device and make full use of the antenna installation space provided by the projectile, the receiving device antenna employs a meandering technique to reduce its size. This involves adjusting the current distribution on the antenna surface and utilizing different resonance modes of the antenna. Slots are created on the antenna surface to extend the mode current, thereby reducing the resonant frequency.
