[0002] With the rapid development of wireless transmission technology, industrial wireless has become the primary choice for solving equipment connectivity issues in scenarios such as frequent equipment movement and harsh production environments within factories, and has become an important component of industrial networks. Currently, the wireless technologies used in the industrial field are mainly standard 5G, WiFi, and Bluetooth protocols. These technologies are primarily geared towards the consumer market, based on shared channels and collision detection and avoidance mechanisms, and cannot guarantee determinism, real-time performance, and reliability of communication. Due to their inability to meet key performance requirements for industrial applications, they can only be used in industrial edge scenarios, such as data acquisition and video surveillance.

[0054] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0055] When using self-developed industrial wireless protocol gateways in industrial scenarios, the gateways use a self-developed communication protocol specific to industrial scenarios, which cannot communicate with standard wireless devices. Therefore, when debugging the gateway devices, the debugging personnel can only go to the site to use wired connections such as USB or network cables to debug the gateway devices. At the installation site, the location and space for debugging are very limited, especially in harsh environments such as high temperature, high humidity, and corrosive gases. This greatly limits the convenience of debugging and deployment efficiency.

[0056] To reduce the dependence of gateway device debugging on physical contact and operating space, in one embodiment, such as Figure 1 As shown, an industrial wireless protocol gateway 100 is provided, including a main control chip 101, and a radio frequency module 102 and a wireless communication module 105 connected to the main control chip 101.

[0057] The radio frequency module 102 uses an industrial scenario communication protocol and communicates with the wireless slave station 104 in the industrial scenario through the first antenna component 103. The wireless communication module 105 uses a standard wireless communication protocol and communicates with the testing equipment 107 through the second antenna component 106.

[0058] The main control chip 101 is the core component for computing and control in the entire industrial wireless protocol gateway. It is primarily responsible for protocol stack operation, service transmission, debugging and monitoring data, clock synchronization, and network key-pump detection. Connected to the RF module 102, the main control chip 101 can send baseband digital signals to the RF transceiver within the RF module 102, or receive demodulated baseband digital signals from the RF transceiver. Connected to the wireless communication module 105, the main control chip 101 can receive debugging data from the wireless communication module 105, or send corresponding debugging interaction data to the testing equipment 107 via the wireless communication module 105.

[0059] In one embodiment, the main control chip 101 can be a system on chip (SOC) in an industrial wireless protocol gateway.

[0060] The radio frequency module 102 is a collection of radio frequency circuits used to generate, transmit, and receive specific frequency bands and modulation methods for industrial scenarios. The communication protocol stack used by the radio frequency module 102 is a non-standard, self-developed wireless communication protocol for industrial scenarios, used to establish a deterministic, low-latency link with the wireless slave station 104.

[0061] In one embodiment, the radio frequency module 102 may include a radio frequency transceiver, a power amplifier, a low-noise amplifier, a filter, an antenna switching switch, and a protocol stack accelerator.

[0062] The wireless communication module 105 is a hardware communication unit that supports general standard wireless technologies. It is a complete module with a built-in standard wireless communication protocol station, capable of establishing a communication connection with any host computer that also supports the standard wireless communication protocol. For example, the wireless communication module 105 may include a Bluetooth communication module, a Wi-Fi communication module, etc.

[0063] In one embodiment, the wireless communication module 105 and the main control chip 101 can be connected using a Universal Asynchronous Receiver / Transmitter (UART), Serial Peripheral Interface (SPI), or Integrated Circuit Bus (IIC) protocol to achieve data interaction, such as transmitting upgrade or configuration commands to the user's wireless connection gateway. Simultaneously, one testing device 107 can be interconnected with multiple industrial wireless protocol gateway master stations, forming a mesh + tree dual-topology network structure, facilitating user testing.

[0064] The first antenna assembly 103 is a passive device system used to convert the guided wave output by the radio frequency (RF) module into free-space electromagnetic waves. It may include one or more antenna radiators with specific frequencies, polarizations, and gains. The resonant frequency and impedance of the first antenna assembly 103 are precisely matched with the operating frequency band of the RF module 102. The RF module 102 can communicate with the wireless slave station 104 in the industrial setting through the first antenna assembly 103.

[0065] In this context, the wireless slave station 104 refers to a terminal device with wireless transceiver capabilities controlled by a gateway master station in an industrial setting. Examples include servo drives, frequency converters, remote I / O modules, sensors, or actuators in industrial environments. The wireless slave station 104 includes a wireless communication interface compatible with the radio frequency module 102, capable of receiving master station commands and sending back status information according to industrial communication protocols. It is understood that the industrial wireless protocol gateway configured with the wireless communication module 105 in this application can be configured at the wireless master station in an industrial setting.

[0066] Among them, the industrial scenario communication protocol is a self-developed wireless communication protocol designed to meet the requirements of industrial automation for deterministic timing, high synchronization accuracy and strict reliability of communication, that is, private or dedicated wireless data exchange rules.

[0067] Standard wireless communication protocols refer to wireless technology specifications developed and publicly released by international standards organizations, aimed at general data communication. Examples of standard wireless communication protocols include, but are not limited to, IEEE 802.11a / b / g / n / ac / ax and IEEE 802.15.1. The design of standard wireless communication protocols prioritizes convenience, compatibility, and user-friendliness, rather than industry-grade deterministic latency.

[0068] Among them, the second antenna component 106 is an electromagnetic wave radiation and reception system adapted to the wireless communication module 105. It can be composed of one or more physical antennas and their matching circuits. Its operating center frequency, bandwidth, polarization mode, gain and other parameters are designed according to the requirements of the standard wireless communication protocol. The second antenna component 106 is used to establish a standardized wireless communication link between the wireless communication module 105 of the gateway and the external debugging equipment 107.

[0069] The debugging device 107 is an external terminal device with standard wireless communication capabilities used for configuring and diagnosing the gateway. The debugging device 107 can be any electronic device running debugging client software and with a built-in standard wireless network card, such as a smartphone, tablet, laptop, or handheld industrial PDA. The debugging device 107 can establish a wireless connection with the industrial wireless protocol gateway without installing any special hardware, sending configuration parameters, querying status, obtaining logs, or upgrading firmware.

[0070] For example, the industrial wireless protocol gateway includes a main control chip 101, and an RF module 102 and a wireless communication module 105 connected to the main control chip 101. The RF module 102 uses a self-developed industrial scenario communication protocol and communicates with a wireless slave station 104 in the industrial scenario via a first antenna component 103. It can modulate the digital signal sent by the main control chip 101 to the RF frequency and transmit it as transmission link data to the corresponding wireless slave station 104 via the first antenna component 103. Alternatively, it can demodulate the RF signal back to a baseband digital signal and send it as reception link data to the main control chip 101. The wireless communication module 105 uses a standard wireless communication protocol and communicates with a testing device 107 via a second antenna component 106. It can perform operations such as transmitting upgrade packages and configuration commands to the user's wireless connection gateway, facilitating remote testing.

[0071] In the above embodiments, the industrial wireless protocol gateway includes a main control chip, and a radio frequency (RF) module and a wireless communication module connected to the main control chip. The RF module uses an industrial scenario communication protocol and communicates with wireless slave stations in the industrial scenario via a first antenna component. It can establish a deterministic, high real-time, and highly reliable communication link with the wireless slave stations in the industrial field, achieving microsecond-level synchronization jitter and millisecond-level communication cycles, meeting the stringent data interaction requirements of core industrial applications such as motion control. The wireless communication module uses a standard wireless communication protocol and communicates with the testing equipment via a second antenna component. This allows debugging personnel to remotely complete equipment debugging without entering hazardous areas with high temperature, high humidity, or corrosive gases, effectively reducing the dependence of gateway equipment debugging on physical contact and operating space, and improving the security and efficiency of gateway deployment.

[0072] In one embodiment, such as Figure 2 As shown, the second antenna assembly includes a 2.4G single-frequency antenna 201, and the first antenna assembly includes a 5G single-frequency antenna 202. The RF module uses an industrial scenario communication protocol and communicates with the wireless slave station in the industrial scenario via the 5G single-frequency antenna 202. The wireless communication module uses a standard wireless communication protocol and communicates with the testing equipment via the 2.4G single-frequency antenna 201. The wireless communication module includes at least one of a Bluetooth communication module or a WIFI communication module.

[0073] Among them, the 2.4G single-frequency antenna 201 is a narrowband electromagnetic wave conversion device that only operates in the 2.4GHz frequency band. It can only radiate or receive electromagnetic waves with a center frequency in the range of approximately 2.4GHz to 2.5GHz. Its physical size, resonant structure and impedance matching are optimized for this frequency band and do not support other frequency bands.

[0074] The 5G single-frequency antenna 202 is a narrowband electromagnetic wave conversion device that only operates in the 5GHz band. It can only effectively radiate or receive electromagnetic waves with a center frequency of approximately 5.1GHz to 5.8GHz. Its physical size is relatively short, and its resonant structure is designed for the corresponding frequency band and does not support other frequency bands.

[0075] Among them, the Bluetooth communication module is a subtype of wireless communication module that specifically implements the Bluetooth protocol stack. It has the standard protocol stack released by the Bluetooth Special Interest Group embedded in it, operates in the 2.4GHz frequency band, and adopts frequency hopping spread spectrum technology. It can mirror pair and exchange data with any Bluetooth-compatible device.

[0076] A Wi-Fi communication module is a subtype of wireless communication module specifically designed to implement the Wi-Fi protocol stack. It internally integrates a Wi-Fi Alliance-certified protocol stack and typically operates in the 2.4GHz frequency band. In industrial wireless protocol gateways, Wi-Fi communication modules can often be used for higher bandwidth debugging tasks, such as transmitting large firmware files or real-time video streams.

[0077] For example, the radio frequency module in the gateway can use an industrial scenario communication protocol to communicate with a wireless slave station in an industrial scenario via a 5G single-frequency antenna 202, and the wireless communication module, i.e., at least one of a Bluetooth communication module or a WIFI communication module, can communicate with the testing equipment via a 2.4G single-frequency antenna 201.

[0078] In the above embodiments, by separating the 5GHz industrial control link from the 2.4GHz standard wireless debugging link, frequency band interference can be effectively reduced. At the same time, the universality of Bluetooth / WIFI is utilized to achieve wireless connection with the debugging equipment, which effectively reduces the dependence of gateway equipment debugging on physical contact and operating space, and improves the security and deployment efficiency of gateway deployment.

[0079] In one embodiment, such as Figure 3 As shown, there are two 5G single-frequency antennas. The radio frequency module 102 includes a main transceiver channel 301 and a diversity transceiver channel 302. The main transceiver channel 301 is connected to the first 5G single-frequency antenna 303, and the diversity transceiver channel 302 is connected to the second 5G single-frequency antenna 304.

[0080] Among them, the first 5G single-frequency antenna 303 is the antenna entity designated to be connected to the main transceiver channel 301 among the two 5G single-frequency antennas. It can be connected to the RF port of the main transceiver channel 301 of the RF module 102 through a feeder and undertake the main transmission and reception tasks.

[0081] The second 5G single-frequency antenna 304 is the antenna entity among the two 5G single-frequency antennas designated to be connected to the diversity transceiver channel 302. It can be connected to the RF port of the diversity transceiver channel 302 of the RF module 102 via a feeder to provide an additional signal path to improve reception quality.

[0082] The main transceiver channel 301 is the primary signal processing path in the radio frequency module 102 responsible for simultaneous signal transmission and reception. This path may include a main power amplifier, a main radio frequency front-end module, a main transceiver common bandpass filter, and a main receiver bandpass filter. The main transceiver channel 301 is used to undertake all transmission tasks and the main reception tasks.

[0083] Diversity transceiver channel 302 is a signal processing path in RF module 102 used for auxiliary reception, and typically does not include transmission functionality or only supports limited transmission. This path may include auxiliary power amplifiers, auxiliary RF front-end modules, auxiliary transceiver common bandpass filters, auxiliary receive bandpass filters, etc. Diversity transceiver channel 302 is responsible for receiving signals from the second 5G single-frequency antenna 304, providing an additional signal copy to the main transceiver channel 301, and improving the received signal-to-noise ratio through selection or combining techniques.

[0084] For example, since multipath fading is common in industrial environments, and a single receiving path is susceptible to signal fluctuations, the RF module 102 is equipped with a main transceiver channel 301 and a diversity transceiver channel 302. The main transceiver channel 301 is connected to the first 5G single-frequency antenna 303, forming the main transceiver link of the RF module 102. The RF module 102 can communicate with wireless slave stations in the industrial environment using industrial scenario communication protocols through the main transceiver link. The diversity transceiver channel 302 is connected to the second 5G single-frequency antenna 304, forming the auxiliary transceiver link of the RF module 102. The auxiliary transceiver link can also communicate with wireless slave stations in the industrial environment using industrial scenario communication protocols.

[0085] In the above embodiments, two 5G single-frequency antennas are used to connect the main transceiver channel and the diversity transceiver channel of the radio frequency module respectively, realizing reception diversity. By using two spatially separated antennas to receive the same signal, the two signals experience different fading paths. After being combined and processed internally by the module, the received signal-to-noise ratio can be effectively improved, thereby enhancing the anti-fading capability of the communication link and improving the reliability of data transmission.

[0086] In another embodiment, such as Figure 4 As shown, the wireless communication module can include both a Bluetooth communication module 401 and a WIFI communication module 402, in which case there are two 2.4G single-frequency antennas.

[0087] The Bluetooth communication module 401 can use a standard wireless communication protocol to communicate with the testing device 107 via a first 2.4G single-frequency antenna 403. The WIFI communication module 402 can use a standard wireless communication protocol to communicate with the testing device 107 via a second 2.4G single-frequency antenna 404.

[0088] Among them, the first 2.4G single-frequency antenna 403 is the antenna entity designated to be connected to the Bluetooth communication module 401 among the two 2.4G single-frequency antennas. It can be connected to the radio frequency output port of the Bluetooth communication module 401 through a feeder and is used to transmit and receive Bluetooth protocol data signals.

[0089] The second 2.4G single-frequency antenna 404 is the antenna entity designated to be connected to the WIFI communication module 402 among the two 2.4G single-frequency antennas. It can be connected to the radio frequency output port of the WIFI communication module 402 through a feeder cable and is used to transmit and receive WIFI protocol data signals.

[0090] For example, a Bluetooth communication module 401 and a Wi-Fi communication module 402 can be simultaneously configured in an industrial wireless protocol gateway. The Bluetooth communication module 401 can communicate with the testing device 107 via a first 2.4G single-frequency antenna 403, using a standard wireless communication protocol for remote information exchange. The Wi-Fi communication module 402 can communicate with the testing device 107 via a second 2.4G single-frequency antenna 404, using a standard wireless communication protocol for remote information exchange.

[0091] In the above embodiments, the industrial wireless protocol gateway integrates both Bluetooth and Wi-Fi modules, each equipped with an independent 2.4GHz single-band antenna, enabling the two standard wireless protocols to operate simultaneously without interference. The Bluetooth module provides a low-power, fast network configuration channel suitable for parameter reading and simple configuration, while the Wi-Fi module provides a high-bandwidth channel to meet the needs of large data transmission such as firmware upgrades and log downloads. The independent antennas effectively reduce impedance mismatch and signal attenuation caused by shared antennas, while eliminating co-channel interference between Bluetooth and Wi-Fi in the 2.4GHz band, thereby improving the flexibility and reliability of debugging.

[0092] In one embodiment, such as Figure 5 As shown, the wireless communication module 105 may include at least one of a Bluetooth communication module or a WIFI communication module, the second antenna component may include a 2.4G / 5G dual-band antenna 501, and the first antenna component includes a 5G single-band antenna 202. The industrial wireless protocol gateway may also include a signal splitting component 502 connected to the 2.4G / 5G dual-band antenna 501.

[0093] The radio frequency module 102 includes a main transceiver channel 301 and a diversity transceiver channel 302. The main transceiver channel 301 is connected to the 5G single-frequency antenna 202, and the diversity transceiver channel 302 is connected to the signal splitter component 502. It is used to communicate with wireless slave stations in the industrial scenario through the 5GHz band of the 2.4G / 5G dual-frequency antenna 501 using an industrial scenario communication protocol.

[0094] The wireless communication module 105 is connected to the signal splitter component 502 and is used to communicate with the testing equipment via the 2.4GHz band of the 2.4G / 5G dual-band antenna 501 using a standard wireless communication protocol.

[0095] Among them, the 2.4G / 5G dual-band antenna 501 is an electromagnetic wave conversion device that can operate simultaneously in two frequency bands, 2.4GHz and 5GHz. The dual-band antenna has two sets of resonant structures inside, sharing the same feed point, and can radiate and receive signals in two frequency bands, 2.4GHz and 5GHz, simultaneously or in a time-division manner.

[0096] The signal splitter component 502 is a device used to separate or combine signals of different frequencies. Internally, it contains two bandpass filters: one allows the 2.4GHz band to pass while blocking the 5GHz band, and the other allows the 5GHz band to pass while blocking the 2.4GHz band. Their common port is connected to a dual-band antenna. The 2.4GHz port of the signal splitter component 502 is connected to the wireless communication module 105, and the 5GHz port is connected to the diversity transceiver channel 302 of the radio frequency module 102, allowing 2.4GHz and 5GHz signals to share the same antenna without interfering with each other.

[0097] In one embodiment, the signal splitter component 502 may include a duplexer.

[0098] For example, to reduce costs, a 2.4G / 5G dual-band antenna 501 and a corresponding signal splitter component 502 can be configured in the industrial wireless protocol gateway. During connection, the wireless communication module 105 can connect to the 2.4GHz port of the signal splitter component 502, communicating with the testing equipment via the 2.4GHz band of the 2.4G / 5G dual-band antenna 501, and exchanging information using standard wireless communication protocols. Meanwhile, the diversity transceiver channel 302 in the RF module 102 can connect to the 5GHz port of the signal splitter component 502, forming an auxiliary transceiver link. This auxiliary transceiver link can communicate with wireless slave stations in the industrial scenario via the 5GHz band of the 2.4G / 5G dual-band antenna 501, exchanging information using industrial scenario communication protocols. The primary transceiver channel 301 can continue to connect to the 5G single-band antenna 202, forming a primary transceiver link that can communicate with wireless slave stations in the industrial scenario using industrial scenario communication protocols.

[0099] In the above embodiments, a 2.4G / 5G dual-band antenna is used to simultaneously carry a 5GHz industrial control link and a 2.4GHz standard debugging link through a signal splitting component, and works in conjunction with a dedicated 5G single-band antenna. The signal splitting component can effectively isolate two different frequency bands and reduce the possibility of frequency band interference. The debugging channel and diversity channel reuse the same dual-band antenna, which can reduce the number of antennas configured in the gateway, thereby reducing structural complexity and construction costs.

[0100] In one embodiment, the wireless communication module includes a Bluetooth communication module, a first WIFI communication module, and a second WIFI communication module. The signal transmission speed of the first WIFI communication module is lower than that of the second WIFI communication module. The second antenna component supports the 2.4GHz band and the 5GHz band.

[0101] The Bluetooth communication module and the first Wi-Fi communication module communicate with the testing equipment via the 2.4GHz frequency band. The second Wi-Fi communication module communicates with the testing equipment via the 5GHz frequency band.

[0102] The first Wi-Fi communication module is a wireless communication sub-module that supports the low-speed Wi-Fi standard, with a lower maximum physical layer transmission rate, typically not exceeding 150Mbps. The second Wi-Fi communication module is a wireless communication sub-module that supports the high-speed Wi-Fi standard, with a higher maximum physical layer transmission rate than the first Wi-Fi communication module.

[0103] The second antenna assembly supports both the 2.4GHz and 5GHz frequency bands, meaning it can cover both bands. For example, it could include both a 2.4GHz single-band antenna and a 5GHz single-band antenna. Alternatively, it could include a 2.4GHz / 5GHz dual-band antenna.

[0104] For example, the wireless communication module may include a Bluetooth communication module, and a first Wi-Fi communication module and a second Wi-Fi communication module with different signal transmission speeds. The second antenna component can operate effectively on both the 2.4 GHz and 5 GHz frequency bands. Since the signal transmission speed of the first Wi-Fi communication module is lower than that of the second Wi-Fi communication module, the Bluetooth communication module and the first Wi-Fi communication module can communicate with the testing device via the 2.4 GHz frequency band of the second antenna component, while the second Wi-Fi communication module, which has a higher signal transmission speed, can communicate with the testing device via the 5 GHz frequency band of the second antenna component.

[0105] In the above embodiments, by integrating three types of wireless interfaces—Bluetooth, low-speed Wi-Fi, and high-speed Wi-Fi—and leveraging the universality of the 2.4GHz band and the high bandwidth of the 5GHz band, layered debugging capabilities are achieved. Bluetooth and low-speed Wi-Fi (2.4GHz) provide low-power, highly compatible configuration channels suitable for rapid on-site pairing and parameter reading. High-speed Wi-Fi (5GHz) provides a high-throughput, low-interference data link, meeting the high-bandwidth requirements of firmware upgrades and log export, enabling the gateway to balance debugging convenience and transmission efficiency, adapting to maintenance tasks in different scenarios.

[0106] In one embodiment, such as Figure 6 As shown, the second antenna assembly may include a first 2.4G single-frequency antenna 403, a second 2.4G single-frequency antenna 404, and a first 5G single-frequency antenna 303. The Bluetooth communication module 401 communicates with the testing equipment via the first 2.4G single-frequency antenna 403, the first Wi-Fi communication module 601 communicates with the testing equipment via the second 2.4G single-frequency antenna 404, and the second Wi-Fi communication module 602 communicates with the testing equipment via the first 5G single-frequency antenna 303.

[0107] For example, the second antenna component may include a single-frequency antenna configured for each communication frequency band. Since both the Bluetooth communication module and the first WIFI communication module 601 are adapted to the 2.4GHz frequency band, the Bluetooth communication module can be connected to the first 2.4G single-frequency antenna 403, and the first WIFI communication module 601 can be connected to the second 2.4G single-frequency antenna 404. The two antennas communicate with the testing equipment via the 2.4GHz frequency of the 2.4G single-frequency antennas and exchange information with the testing equipment using standard wireless communication protocols.

[0108] Because the second WIFI communication module 602 has a higher signal transmission speed, it is more compatible with the 5GHz frequency band. Therefore, the second WIFI communication module 602 can be connected to the first 5G single-frequency antenna 303 to communicate with the testing equipment via the 5GHz frequency and exchange information with the testing equipment using the standard wireless communication protocol.

[0109] At this time, the first antenna component may include a second 5G single-frequency antenna 304. The radio frequency module 102 can connect to the wireless slave station in the industrial scenario through the second 5G single-frequency antenna 304 and use the industrial scenario communication protocol to exchange information with one or more wireless slave stations.

[0110] In the above embodiments, the gateway is equipped with independent antennas for Bluetooth, low-speed WIFI and high-speed WIFI respectively. Two 2.4G single-frequency antennas serve Bluetooth and low-speed WIFI respectively, reducing the risk of impedance mismatch and co-channel interference caused by sharing antennas. An additional 5G single-frequency antenna is dedicated to high-speed WIFI, which can protect it from the congestion of the 2.4GHz band. This realizes the possibility of three debugging links working in parallel without mutual constraints, and takes into account the flexibility and stability of low-power network configuration and high-speed data transmission.

[0111] In another embodiment, such as Figure 7 As shown, the second antenna component includes a 2.4G / 5G dual-band antenna 501, a 2.4G single-band antenna 201, and a first 5G single-band antenna 303. The industrial wireless protocol gateway may also include a signal splitting component 502 connected to the 2.4G / 5G dual-band antenna 501.

[0112] The Bluetooth communication module 401 is connected to the signal splitter component 502 and is used to communicate with the testing equipment via the 2.4GHz frequency band of the 2.4G / 5G dual-band antenna 501. The first Wi-Fi communication module 601 communicates with the testing equipment via the 2.4G single-band antenna 201. The second Wi-Fi communication module 602 communicates with the testing equipment via the first 5G single-band antenna 303.

[0113] The radio frequency module 102 includes a main transceiver channel 301 and a diversity transceiver channel 302. The main transceiver channel 301 is connected to the first antenna assembly 103 for communication with the wireless slave station in the industrial scenario. The diversity transceiver channel 302 is connected to the signal splitter assembly 502 and is used to communicate with the wireless slave station through the 5GHz band of the 2.4G / 5G dual-band antenna 501.

[0114] For example, to reduce construction costs, a 2.4G / 5G dual-band antenna 501 can be used to construct an auxiliary transceiver link for the RF module 102. This involves connecting the 2.4G / 5G dual-band antenna 501 to the common port of the signal splitter component 502. Subsequently, the Bluetooth communication module 401 can connect to the 2.4GHz port of the signal splitter component 502, communicating with the testing equipment via the 2.4GHz band of the 2.4G / 5G dual-band antenna 501 and exchanging information using standard wireless communication protocols. The diversity transceiver channel 302 in the RF module 102 can connect to the 5GHz port of the signal splitter component 502, forming an auxiliary transceiver link. This auxiliary transceiver link can communicate with wireless slave stations in industrial scenarios via the 5GHz band of the 2.4G / 5G dual-band antenna 501, exchanging information using industrial scenario communication protocols. Based on this, the first Wi-Fi communication module 601 can connect to the 2.4G single-band antenna 201, exchanging information with the testing equipment using standard wireless communication protocols. The second WIFI communication module 602 can be connected to the first 5G single-frequency antenna 303 to exchange information with the testing equipment using standard wireless communication protocols. Meanwhile, the master transceiver channel 301 in the RF module 102 can be connected to the wireless slave station in the industrial scenario through the first antenna assembly, i.e., the second 5G single-frequency antenna 304, to exchange information using industrial scenario communication protocols.

[0115] In the above embodiments, a duplexer enables a single dual-band antenna to simultaneously carry Bluetooth debugging and industrial control diversity links, effectively reducing the number of antennas and lowering construction costs. Meanwhile, Bluetooth and low-speed Wi-Fi use different 2.4G antennas, avoiding frequency hopping and co-channel interference. With high-speed Wi-Fi exclusively using the 5G antenna, the high throughput of high-speed Wi-Fi can be achieved without contention. Furthermore, the industrial master and diversity channels work together, utilizing the 5GHz portion of the dual-band antenna to obtain diversity gain, effectively balancing debugging flexibility, industrial reliability, and high-speed transmission performance.

[0116] In one embodiment, such as Figure 8 As shown, the second antenna component may include a 2.4G / 5G dual-band antenna 501 and a 2.4G single-band antenna 201. The industrial wireless protocol gateway may also include a signal splitter component 502 connected to the 2.4G / 5G dual-band antenna 501.

[0117] The Bluetooth communication module 401 is connected to the testing equipment via a 2.4G single-band antenna 201. The first Wi-Fi communication module 601 and the second Wi-Fi communication module 602 are connected to the signal splitter component 502. The first Wi-Fi communication module 601 is connected to the testing equipment via the 2.4GHz band of the 2.4G / 5G dual-band antenna 501, and the second Wi-Fi communication module 602 is connected to the testing equipment via the 5GHz band of the 2.4G / 5G dual-band antenna 501.

[0118] For example, since the first Wi-Fi communication module 601 and the second Wi-Fi communication module 602 are adapted to different frequency bands, a 2.4G / 5G dual-band antenna 501 and a signal splitter component 502 connected to it can be configured. The common port of the signal splitter component 502 is connected to the 2.4G / 5G dual-band antenna 501. The first Wi-Fi communication module 601 can connect to the 2.4GHz port of the signal splitter component 502 and communicate with the testing equipment through the 2.4GHz frequency band of the 2.4G / 5G dual-band antenna 501, using a standard wireless communication protocol for information exchange. The second Wi-Fi communication module 602 can connect to the 5GHz port of the signal splitter component 502 and communicate with the testing equipment through the 5GHz frequency band of the 2.4G / 5G dual-band antenna 501, using a standard wireless communication protocol for information exchange. The Bluetooth communication module 401 still communicates with the testing equipment through the 2.4G single-band antenna 201, using a standard wireless communication protocol for information exchange.

[0119] In the above embodiments, a signal splitting component enables a single 2.4G / 5G dual-band antenna to simultaneously carry low-speed WIFI (2.4GHz) and high-speed WIFI (5GHz), while a separate 2.4G single-band antenna is configured for the Bluetooth communication module. This achieves optimization of the number of antennas and frequency band isolation, ensuring the stability and transmission efficiency of the parallel operation of the three debugging links of Bluetooth, low-speed WIFI and high-speed WIFI while reducing the number of antennas.

[0120] In one embodiment, such as Figure 9 As shown, the second antenna component may include a first 2.4G / 5G dual-band antenna 901 and a second 2.4G / 5G dual-band antenna 902. The industrial wireless protocol gateway may also include a first signal splitter component 903 connected to the first 2.4G / 5G dual-band antenna 901 and a second signal splitter component 904 connected to the second 2.4G / 5G dual-band antenna 902.

[0121] The Bluetooth communication module 401 is connected to the first signal splitter component 903 and is used to communicate with the testing equipment via the 2.4GHz band of the first 2.4G / 5G dual-band antenna 901. The first WIFI communication module 601 and the second WIFI communication module 602 are respectively connected to the second signal splitter component 904. The first WIFI communication module 601 is connected to the testing equipment via the 2.4GHz band of the second 2.4G / 5G dual-band antenna 902, and the second WIFI communication module 602 is connected to the testing equipment via the 5GHz band of the second 2.4G / 5G dual-band antenna 902.

[0122] The radio frequency module 102 includes a main transceiver channel 301 and a diversity transceiver channel 302. The main transceiver channel 301 is connected to the wireless slave station in the industrial scenario via the first antenna assembly 103. The diversity transceiver channel 302 is connected to the first signal splitter assembly 903 and is used to communicate with the wireless slave station in the industrial scenario via the 5GHz band of the first 2.4G / 5G dual-band antenna 901.

[0123] For example, in order to further reduce the cost of gateway construction, two 2.4G / 5G dual-band antennas can be set in the industrial wireless protocol gateway, and corresponding signal splitting components can be configured for each of them. That is, the first 2.4G / 5G dual-band antenna 901 is connected to the common port of the first signal splitting component 903, and the second 2.4G / 5G dual-band antenna 902 is connected to the common port of the second signal splitting component 904.

[0124] The Bluetooth communication module 401 is connected to the 2.4GHz port of the first signal splitter component 903, and communicates with the testing equipment via the 2.4GHz band of the first 2.4G / 5G dual-band antenna 901, using standard wireless communication protocols for information exchange. Simultaneously, the diversity transceiver channel 302 of the RF module 102 is connected to the 5GHz port of the first signal splitter component 903, and communicates with the wireless slave station in the industrial scenario via the 5GHz band of the first 2.4G / 5G dual-band antenna 901, using industrial scenario communication protocols for information exchange. The master transceiver channel 301 of the RF module 102 can be connected to the first antenna component 103, for example, to a 5G single-band antenna, and communicates with the wireless slave station in the industrial scenario through the first antenna component.

[0125] Since the first WIFI communication module 601 and the second WIFI communication module 602 are adapted to different communication frequency bands, the first WIFI communication module 601 can be connected to the 2.4GHz port of the second signal splitter component 904, and communicate with the testing equipment through the 2.4GHz frequency band of the second 2.4G / 5G dual-band antenna 902, using standard wireless communication protocols for information exchange. Similarly, the second WIFI communication module 602 can be connected to the 5GHz port of the second signal splitter component 904, and communicate with the testing equipment through the 5GHz frequency band of the second 2.4G / 5G dual-band antenna 902, using standard wireless communication protocols for information exchange.

[0126] In the above embodiment, the gateway uses two 2.4G / 5G dual-band antennas and is equipped with duplexers respectively. The first antenna simultaneously carries Bluetooth debugging (2.4GHz) and industrial control diversity link (5GHz), and the second 2.4G / 5G dual-band antenna simultaneously carries low-speed WIFI (2.4GHz) and high-speed WIFI (5GHz). Thus, by using only two dual-band antennas, three debugging links in parallel and industrial control diversity reception are achieved, which balances the reduction of antenna quantity and performance optimization.

[0127] Understandably, an industrial wireless protocol gateway may include, in addition to the main control chip, RF module, antenna assembly, and wireless communication module, other necessary components. In one embodiment, such as... Figure 10 As shown, an industrial wireless protocol gateway device is provided. The device may include a SOC system 1001, an FPGA (Field-Programmable Gate Array) system 1002, an encryption unit 1003, a physical layer (PHY) chip 1004, an RJ45 network port 1005, a 485 port 1006, a CAN port 1007, a WIFI / Bluetooth module 1008, a radio frequency module 102, a duplexer 1009, a 5.8G single-band antenna 1010, and a 5.8G / 2.4G dual-band antenna 1011.

[0128] The radio frequency module 102 has two transmit and two receive channels. One main transceiver link is connected to the 5.8G single-frequency antenna 1010, and the other auxiliary transceiver link is connected to the 5.8G / 2.4G dual-frequency antenna 1011 through the duplexer 1009. Within the radio frequency module 102, the two transceiver channels use the same devices and structural topology, specifically including: radio frequency transceiver, two power amplifiers (PA), two radio frequency front-end modules (FEM), two common transceiver bandpass filters, and two receive bandpass filters.

[0129] The radio frequency front-end module may include an internal power amplifier (PA), a low-noise amplifier (LNA), a transceiver switch, and a bypass mode.

[0130] The digital side of the RF transceiver is connected to the SOC system 1001, and the analog side of the RF transceiver is connected to two transmit PAs and two receive bandpass filters. It is responsible for modulating the digital signal of the SOC system 1001 to the RF frequency and transmitting it as transmit link data, or demodulating the RF signal back to the baseband digital signal and transmitting it as receive link data to the SOC system 1001.

[0131] The output of the internal power amplifier of the RF front-end module is connected to the transmitting end of the transceiver switch of the RF front-end module, which is responsible for further amplifying the signal output by the power amplifier.

[0132] The input of the power amplifier is connected to the RF transceiver, and the output of the power amplifier is connected to the input of the internal power amplifier (PA) of the RF module 102, which is responsible for amplifying the weak RF signal generated by the RF transceiver.

[0133] The receiving end of the transmit / receive switch of the RF front-end module is connected to the input end of the low-noise amplifier of the RF front-end module. It is responsible for transmitting the output data of the power amplifier through the transmit / receive common bandpass filter to the 5.8G single-band antenna 1010 and the 5.8G / 2.4G dual-band antenna 1011 during transmission, and transmitting the received data of the transmit / receive switch through the low-noise amplifier or bypass mode to the receive bandpass filter during reception.

[0134] The input and output terminals of the low-noise amplifier in the RF front-end module are connected in bypass mode, which is responsible for amplifying the weak RF signal received from the antenna without significantly increasing the noise.

[0135] The bypass mode terminals of the RF front-end module are connected to the input and output terminals of the low-noise amplifier. The bypass mode is controlled by the SOC system 1001. If the bypass mode is enabled, the weak RF signal received from the antenna will be directly transmitted to the receiving bandpass filter.

[0136] The transmit / receive common bandpass filter's frequency range includes, but is not limited to, the legally permitted 2.4GHz (2400-2483.5MHz), 5.1GHz (5150-5350MHz), and 5.8GHz (5725-5850MHz), and extends to include the potentially future 6GHz (5850-6425MHz) spectrum. In the main transmit / receive link, the transmit / receive common bandpass filter is connected at both ends to the transmit / receive switching switch of the RF front-end module and the 5.8GHz single-band antenna 1010, respectively. In the secondary transmit / receive link, the transmit / receive common bandpass filter is connected to the 5.8G / 2.4G dual-band antenna 1011 through one input and one output of the duplexer 1009, responsible for filtering the antenna's transmit and receive data, allowing only signals within the frequency range of 5150MHz to 5850MHz to pass through.

[0137] The frequency range of the receiving bandpass filter is 5725MHz~5850MHz, which includes but is not limited to the spectrum permitted by regulations. The two ends of the receiving bandpass filter are connected to the low noise amplifier or bypass mode of the RF front-end module and the analog side of the RF transceiver, respectively. It is responsible for performing secondary filtering on the received data from the antenna, allowing only signals with a frequency range of 5725MHz~5850MHz to pass through.

[0138] The SOC system 1001 is connected to the encryption unit 1003, the FPGA system 1002, the digital side of the RF transceiver, the WIFI / Bluetooth module 1008, the 485 port 1006, and the CAN port 1007. When the gateway is powered on, the SOC system 1001 sends a key to the encryption unit 1003 for identification. Only after successful identification can the software services run. The SOC system 1001 connects to the FPGA system 1002 for transmitting service data, debugging and monitoring data, clock synchronization, and detecting network key jumps. The SOC system 1001 connects to the digital side of the RF transceiver, responsible for sending baseband digital signals to the RF transceiver or receiving the demodulated baseband digital signals from the RF transceiver. The SOC system 1001 connects to the WIFI / Bluetooth module 1008 for transmitting debugging data. The SOC system 1001 connects to the 485 port 1006 for data interaction with external devices. The SOC system 1001 connects to the CAN port 1007 for data interaction with external devices.

[0139] The FPGA system 1002 is connected to the SOC for transmitting service data, debugging and monitoring data, clock synchronization, and detecting network key jumps. The FPGA system 1002 is also connected to the PHY chip 1004 of the RJ45 network port 1005 for sending and receiving service data.

[0140] The encryption unit 1003 is connected to the SOC system 1001 and identifies the key output by the SOC system 1001 through the IO single-line protocol. Only after successful identification can the entire gateway service software package be run; otherwise, the gateway service cannot run normally.

[0141] The WIFI / Bluetooth module 1008 and the SOC system 1001 use UART / SPI / IIC protocols for data interaction, enabling users to wirelessly connect to the gateway to transmit upgrade packages or configuration commands. At the same time, it can interconnect one host computer with multiple industrial wireless protocol gateway master stations to realize a mesh + tree dual-topology network structure, which is convenient for users to debug.

[0142] The RJ45 network port 1005 connects to the PHY chip 1004, enabling the transmission of data from controllers such as PLCs to industrial wireless protocol gateway slave stations via the industrial wireless protocol master station. The slave station then converts the wireless data into wired data for transmission to actuators such as motors, servos, frequency converters, I / O devices, and valve islands.

[0143] The two input ports of the duplexer 1009 are connected to the common bandpass filter of the auxiliary transceiver link and the WIFI / Bluetooth module 1008, respectively. The output port of the duplexer 1009 is connected to the 5.8G / 2.4G dual-band antenna 1011, so that the auxiliary transceiver link and the WIFI / Bluetooth module 1008 can transmit and receive signals simultaneously, and can effectively isolate the transmitted and received signals to prevent them from interfering with each other.

[0144] The 5.8G single-band antenna 1010 is connected to the common bandpass filter of the main transceiver link to enable the transmission and reception of signals from the main transceiver link. The 5.8G / 2.4G dual-band antenna 1011 is connected to the output port of the duplexer 1009 to enable the transmission and reception of signals from the auxiliary transceiver link and the WIFI / Bluetooth module 1008.

[0145] The 485 port 1006 connects to the SOC system 1001 for data exchange with external devices such as a PLC. The CAN port 1007 connects to the SOC system 1001 for data exchange with external devices such as a PLC.

[0146] like Figure 11 As shown, by setting up common wireless standard modules such as WIFI or Bluetooth in the above-mentioned industrial wireless protocol gateway device and adopting a common antenna scheme, and using common wireless standards such as WIFI or Bluetooth Mesh in terms of software, remote debugging and upgrading of the gateway can be realized. When there are multiple sets of self-developed industrial wireless protocol gateway master stations and slave stations in the industrial field, one host computer can be interconnected with multiple industrial wireless protocol gateway master stations to realize a mesh + tree dual topology network structure, which is convenient for users to remotely debug and use.

[0147] The debugging method for users to remotely debug the device via a host computer can be as follows: Figure 12 As shown, for example, users can use a host device such as a mobile phone or computer to log in to the Mesh network using an Internet Protocol address (IP) or a domain name assigned by the Mesh network. After entering their username and password, they can access the debugging interface. In the debugging interface, users can select operation commands or perform operations such as uploading or downloading files. The HTTP / HTTPS requests sent by the browser are encapsulated into Transmission Control Protocol / Internet Protocol (TCP / IP) packets and enter the Mesh node network. The Mesh protocol automatically selects the optimal path based on its internal routing table, ultimately forwarding the packets to the Mesh node connected to the target industrial wireless protocol gateway master system.

[0148] The web server of the industrial wireless protocol gateway master system receives and parses HTTP / HTTPS requests. This includes parsing corresponding operation commands, toggling the level of a general-purpose input / output (GPIO) device, processing uploaded files, and writing the received data stream into the flash memory of the industrial wireless protocol gateway master system. Alternatively, it can process downloaded files, read local files, and send them as attachments to HTTP responses.

[0149] Based on the processing results, the web server generates an HTTP response. The response data packet returns along the Mesh network path (which may be different from the request path) and eventually reaches the user's browser.

[0150] The test webpage is dynamically updated using a scripting language (JavaScript) to display "Command sent successfully" or new sensor data.

[0151] The aforementioned industrial wireless protocol gateway device and its corresponding commissioning method, by adding a WIFI / Bluetooth module, overcome the shortcomings of self-developed industrial wireless protocol gateways, such as the inability to remotely commission and upgrade. This enables remote commissioning and upgrades without manual intervention in the field, greatly simplifying the maintenance and upgrade process, improving on-site commissioning efficiency, and reducing the possibility of on-site safety and operational errors. Employing a duplexer and dual-band antenna design, it simultaneously transmits and receives data in both the 2.4G and 5.8G bands. The 2.4G band enables remote commissioning, while the 5.8G band enables the self-developed wireless protocol service functions.
