[0020] The present utility model will now be further described in detail in conjunction with the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0021] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0022] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0023] As shown in the figure, the WIFI terminal device with IO-Link communication function of the present utility model includes: a housing 1, a WIFI chip 2 and an IO-Link master transceiver 3 are arranged inside the housing 1, and the WIFI chip 2 and the IO-Link master transceiver 3 are connected through the SPI communication protocol; the IO-Link master transceiver 3 has a plurality of IO-Link interfaces, the WIFI chip 2 has a WIFI interface and an ETH interface; the IO-Link interface is used to connect sensors, the WIFI interface is used to send sensing data to the industrial Ethernet, and the ETH interface is used to connect a computer for setting and debugging device parameters.

[0024] That is to say, the utility model integrates the WIFI function and the IO-Link master in one device, enabling a WIFI terminal device to not only connect to a WIFI AP but also connect to different sensors (such as temperature sensors, humidity sensors, etc.) through the IO-Link interface. It can also send configuration parameters to the sensors through the IO-Link interface and send the data collected by the IO-Link interface to the industrial Ethernet through the WIFI interface. That is, in this embodiment, by improving the WIFI terminal device and adding the IO-Link master function inside the WIFI terminal device, it is possible to initialize, configure, and obtain data from the IO-Link slave devices, and after processing, upload it to the industrial Ethernet through WIFI. The WIFI terminal device of the utility model has multiple functions and can meet different communication requirements.

[0025] Specifically, the WIFI chip 2 includes: an SPI interface, a WIFI AP interface, a PCIE interface, a GPIO interface, a DDR interface, an eMMC interface, and an MII interface. The SPI interface is connected to the IO-Link host transceiver 2. The WIFI AP interface is connected to a first radio frequency front-end module. The PCIE interface is connected to a 5G wireless chip, and the 5G wireless chip is connected to a second radio frequency front-end module. The GPIO interface is connected to the LED indicator through a shift register.

[0026] It should be noted that the SPI (Serial Peripheral Interface) interface is based on a high-speed full-duplex communication bus and can achieve high-speed communication. The WIFI AP refers to a wireless access point, and wireless communication can be achieved after connecting to the WIFI AP interface. The PCIE (peripheral component interconnect express) interface realizes signal transmission based on a high-speed serial computer expansion bus.

A 5G wireless chip is connected through the PCIE interface, enabling the device to support communication in the 5GHz band. The WIFI chip 2 comes with a communication function in the 2.4GHz band. The first radio frequency front-end module is used to enhance the WIFI communication ability, and the second radio frequency front-end module is used to enhance the 5G communication ability. The radio frequency switch is used to control the on / off of 5G communication and WIFI communication, realizing the switching of different communication bands. The indicator light is used to display the current operating state of the WIFI terminal device. The number of indicator lights is four, and the current operating mode of the WIFI terminal device (such as 5G communication, WIFI communication, data transmission and reception, etc.) can be understood by observing the on / off of different indicator lights.

The IPQ4019 chip has the advantages of high performance, low cost, low power consumption, high stability, strong security, and support for high-speed network interfaces. The model of the IO-Link host transceiver 3 is MAX14819.

The MAX14819 chip can reduce the power consumption by up to 50% and is fully compatible with IO-Link communication in all modes, making it suitable for use in underground environments. The 5G wireless chip is QCN6102, supporting the 802.11b / g / n standard, adopting a 28nm process to bring lower power consumption, suitable for low-power, low-speed network environments, and supporting 5G Wi-Fi technology.
