Description

Technical Field

[0001] The present invention belongs to the technical field of industrial field equipment, and in particular relates to a contactless connection method, system and related equipment between industrial field equipment. Background Art

[0002] In industrial environments, control systems and electronic equipment face a series of severe environmental challenges, including continuous vibration, high concentrations of dust, salt corrosion, and humidity changes. These factors not only affect the normal operation of the equipment, but are also particularly prone to loosening, aging, and corrosion of the connecting wires and connector ports, which in turn lead to equipment failures, performance degradation, and even safety issues. In order to deal with these problems, the existing technology usually adopts the following measures: (1) Selecting vibration-resistant, corrosion-resistant, dust-proof and waterproof connecting wires and connectors. For example, using stainless steel or nickel-plated connector shells, and oil-resistant and chemical-resistant insulating materials. Selecting waterproof connectors, including using O-rings or sealing gaskets to prevent water and moisture intrusion. (2) Strengthening connection design: Consider increasing the stability of the connection point during design, such as using locking screws, locking buckles or crimping connectors to ensure a stable connection. For areas with frequent vibration, use elastic elements (such as shock pads) to absorb vibration energy and reduce the impact on the connector. (3) Regular maintenance and inspection: Develop a regular maintenance plan, including checking the tightness, corrosion, and insulation performance of the connecting wires and connectors. Use professional cleaning tools and methods to regularly clean dust, salt and other pollutants from the connector ports and surrounding areas. Replace aging cables and connectors in a timely manner to avoid malfunctions. (4) Improve the industrial environment as much as possible, such as installing dust covers, ventilation equipment and humidity control devices to reduce the impact of dust, humidity and salt on the equipment. For particularly harsh environments, consider using sealed boxes or airtight chambers to isolate the equipment to ensure a stable internal environment. (5) Use protective coatings: Apply anti-corrosion and moisture-proof coatings, such as epoxy resin or polyurethane coatings, to connectors and cables to increase their ability to resist harsh environments. At the same time, ensure that the coating does not affect the electrical conductivity and signal transmission performance of the connector.

BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required for use in the embodiments are briefly introduced below. It should be understood that the following drawings only show some embodiments of the present invention. For ordinary technicians in this field, other related drawings can be obtained based on these drawings without creative work.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, ordinary technicians in this field can also obtain other embodiments without making creative work.

[0019] The contactless connection solution is a cable-free solid-state device that uses high-speed millimeter-wave RF transceivers and antennas to send and receive signals, thereby achieving wireless data transmission between short-range devices. This technology can achieve data or electrical continuity without the need for physical connections, thus completely getting rid of the constraints of traditional flexible cables. Flexible cables are easily affected by harsh environments such as vibration, dust, salt and humidity during long-term use, resulting in loosening, aging, corrosion and other problems. Contactless connections eliminate these physical connection points, reduce the possibility of failure, and improve the overall reliability of the device.

[0020] Since there is no need to leave space for flexible cables, designers can plan the internal structure of the equipment more flexibly, making the equipment more compact and beautiful. At the same time, damage and replacement of flexible cables usually require high maintenance costs. Contactless connection reduces these maintenance needs and reduces overall maintenance costs. In harsh industrial environments, flexible cables are susceptible to contamination and damage, while contactless connection solutions can achieve fully sealed product designs, minimizing damage that may be caused by dust, dirt and moisture, thereby improving the adaptability of equipment in harsh environments.

[0021] See also Figure 1 The non-contact connection method between industrial field devices according to an embodiment of the present invention comprises the following steps: S1. RF transceivers are respectively arranged on the industrial field devices to be connected; wherein the mounting holes of the RF transceivers are respectively arranged on the shell surfaces of the industrial field devices, and the RF transceivers between the shell surfaces of the industrial field devices are aligned with each other to form a cross-radiation; wherein the RF transceivers of the industrial field devices are pre-set with the same network identifier.

[0022] S2. Pairing the radio frequency transceivers based on the network identifier and establishing a wireless link between the corresponding radio frequency transceivers, and the industrial field device transmits the data to be sent and received to the radio frequency transceiver through an interface.

[0023] S3. The RF transceiver converts the data to be sent or received into a RF signal of a preset frequency, and transmits the RF signal of the preset frequency between corresponding RF transceivers according to a wireless link.

[0024] In a possible implementation, in the step of respectively setting up radio frequency transceivers on the industrial field devices that need to be connected, the radio frequency transceivers use the unlicensed 60GHz radio frequency millimeter wave band. 60GHz millimeter wave communication is a wireless communication technology that uses frequencies near 60GHz. Due to the available spectrum width of 5~9GHz, it can achieve ultra-high-speed wireless transmission of several Gbps between devices. Using the 60GHz millimeter wave as the communication carrier, the industrial field devices use a custom communication protocol to achieve data parsing and control functions between industrial field devices.

[0025] In a possible implementation manner, in the step of respectively providing a radio frequency transceiver on the industrial field devices to be connected, the radio frequency transceiver supports a multi-gigabit data rate.

[0026] Furthermore, the data transmission speed of the RF transceiver described in the embodiment of the present invention is 6.25 Gbps.

[0027] Furthermore, in the embodiment of the present invention, the power consumption between each pair of RF transceivers is 72 mW, and the delay is 7 ns.

[0028] In a possible implementation manner, when pairing the RF transceivers and establishing a wireless link between the corresponding RF transceivers, the interface type supported by the wireless link includes at least one of the following: Universal Serial Bus USB, Ethernet, digital display interface DisplayPort, serial advanced technology attachment SATA, peripheral expansion interconnect bus PCIe, integrated circuit bus I2C, universal asynchronous receiver and transmitter UART and general purpose input and output GPIO.

[0029] Furthermore, the Universal Serial Bus (USB) is an interface standard for connecting computers to external devices. The USB interface has the characteristics of plug-and-play, hot-swap, fast transmission speed, and support for multiple device connections. The digital display interface (DisplayPort) is mainly used to connect computers and monitors and other devices to transmit video and audio signals. The digital display interface has the characteristics of high-speed transmission, high bandwidth, and support for multiple monitor connections. It is widely used in computers, monitors, projectors and other devices. Serial Advanced Technology Attachment (SATA) is a computer bus that is mainly used to connect data between a host and a large number of storage devices (such as hard drives, optical drives, etc.). The SATA interface has a high-speed data transfer rate, low cost and good compatibility. Peripheral Component Interconnect Express (PCIe) is a high-speed serial computer expansion bus standard used to connect high-speed peripherals such as graphics cards, solid-state drives, network interface controllers, etc. PCIe has high bandwidth, low latency and excellent scalability. The integrated circuit bus I2C is a serial communication bus, which is mainly used to connect low-speed peripherals, such as sensors, electrically erasable programmable read-only memory (EEPROM), liquid crystal display (LCD), etc., and realizes data communication between devices through two lines (serial data line (SDA) and serial clock line (SCL)). The I2C bus is simple, efficient and easy to expand. The Universal Asynchronous Receiver / Transmitter (UART) is an asynchronous serial communication protocol used for data exchange between microprocessors and external devices. UART sends and receives data through a transmission line and a receiving line. At the same time, a ground line and a signal ground line can be selectively used to reduce interference. The UART communication protocol is simple and reliable, and is widely used in computers, embedded systems, communication equipment and other fields. General Purpose Input / Output (GPIO) is a set of pins that allows a microcontroller or microprocessor to interact with external devices such as sensors, Light Emitting Diode (LED) lights, buttons, etc.GPIO pins can be configured in input mode to read the status of external devices, or in output mode to control the on / off status of external devices.

[0030] In a possible implementation, when a radio frequency transceiver is provided on an industrial field device in an embodiment of the present invention, an AiP integrated antenna configuration is adopted to integrate the radio frequency transceiver and a corresponding internal chip of the industrial field device into the same package.

[0031] AiP (Antenna in Package) integrated antenna configuration is a technology that integrates antennas with circuits to achieve a single package for antennas and RF components. AiP technology integrates antennas and chips in a package through packaging technology to achieve system-level wireless functions. This technology takes into account the performance, cost and volume of the antenna and has the advantage of high integration. AiP technology is widely used in 5G millimeter wave frequency band terminal antennas and is a key technology for achieving application scenarios such as millimeter wave high-resolution data streams and mobile distributed computing. At the same time, it is also suitable for 2.4GHz Internet of Things, 60GHz virtual reality, augmented reality and gesture recognition. AiP technology integrates components such as antennas, RF transceivers, RF front-end integration, and power management chips into a compact module, greatly reducing the size and thickness of the device. Due to the close integration of antennas and RF front-end components, the loss caused by the RF feeder is reduced, and the signal integrity and effective radiated power are improved.

[0032] Through integrated design, AiP technology reduces the demand for high-frequency substrate materials, thereby reducing overall costs. At the same time, integrated design also simplifies the production process and improves production efficiency. AiP technology provides greater flexibility for millimeter wave antenna design, which can be customized and optimized according to different application scenarios and needs. AiP technology integrates the antenna and chip in the package based on packaging materials and processes. The current mainstream packaging processes include Low Temperature Co-fired Ceramic (LTCC), High Density Interconnect (HDI) and Fan Out Wafer Level Packaging (FOWLP). Among them, the FOWLP process has become the mainstream technology process for AiP antennas due to its advantages such as higher integration, better heat dissipation and lower transmission loss. AiP integrated antenna design needs to consider factors such as antenna type, size, and layout. With the continuous advancement of semiconductor packaging technology, the integration of AiP technology will be further improved, and more components will be integrated into a single package. As production scale expands and processes are optimized, the cost of AiP technology will gradually decrease, thereby promoting its application in a wider range of fields.

[0033] The contactless connection method between industrial field devices in the embodiment of the present invention adopts a 60GHz radio frequency transceiver, which can provide a very energy-saving high data rate wireless link, and can get rid of the need for physical cables and connectors in short-distance point-to-point communications, providing a good solution for short-distance contactless connection. The present invention develops a connector-free solution based on this technology, which can be used to design waterproof and dustproof wireless devices, and can be applied to harsh industrial environments to avoid environmental interference on the connector port. The contactless connection method between industrial field devices of the present invention can be applied to application scenarios such as wireless connection of human-machine interface (HMI) display screens between industrial field devices and wireless connection of input / output (IO) bases between industrial field devices.

[0034] The embodiment of the present application uses the unlicensed 60GHz radio frequency millimeter wave band, with a data transmission speed of up to 6.25Gbps, which can achieve multi-gigabit data rates, and also has the characteristics of ultra-low power consumption, contactless point-to-point, ultra-low latency, etc. The power consumption of a pair of transceivers of this contactless connector is only 72mW, and the latency is only 7ns, which is equivalent to a physical connector. Therefore, it can provide a very energy-saving high-data-rate wireless link and get rid of the need for physical cables and connectors in short-distance point-to-point communications.

[0035] The present invention proposes a hardware solution that can achieve point-to-point secure connection without software development or login, can work like a real connector, and supports a wide range of signal interface types. It is transparent to the interface type and protocol, as long as the signal characteristics meet the electrical specifications of the transceiver interface signal.

[0036] The contactless connection method between industrial field devices in the embodiment of the present invention can achieve signal integrity: the 60GHz RF receiver wirelessly transmits its signal from the transmitter to the receiver through the air or the device housing. Because there is no electrical connection inherent in traditional connectors, there are no problems such as loss and impedance mismatch that traditional connectors face as the bandwidth increases. In high-speed transmission mode, the amplitude value of the differential signal input to the transmitter can support a minimum of 100mV, which can meet the loss requirements of most embedded systems, interconnect cables, etc. Using the 60GHz RF receiver wireless connection technology, the signal recovered by the receiving end has the same characteristics as the transmitting end, and no signal distortion will occur.

[0037] The contactless connection method between industrial field devices in the embodiment of the present invention can achieve reliable transmission. The use of a 60GHz radio frequency receiver eliminates the electrical connection of the metal probe of the traditional connector, so there will be no problems such as wear and aging caused by the plug-in process of the socket, plug, B2B connector, etc. The connection process is more reliable and the service life is longer. Moreover, since the transmitter and receiver can be embedded in the device housing, a true interface-free connection is achieved, so it will not be affected by environmental conditions such as water, dust, vibration, etc., and the transmission is more stable and reliable.

[0038] The contactless connection method between industrial field devices in the embodiment of the present invention supports flexible antenna configuration to meet the requirements of different designs and application scenarios. The AiP integrated antenna configuration is selected, and no antenna design is required, which can be quickly and easily integrated into the customer product design; the external antenna can use a printed circuit board (PCB) onboard antenna, horn antenna, etc. to meet the requirements of radiation mode, transmission distance, etc. in different applications; the waveguide design can achieve more flexible transmission distance, angle, 360° rotation and other design requirements.
