Embodiment 1
[0036] A data connection interface has an appearance of a network interface; specifically, the appearance of the network interface in this embodiment may be an appearance of an RJ45 interface. Alternatively, the appearance of network interfaces such as RJ-11 interface, SC optical fiber interface, FDDI interface, AUI interface, BNC interface, and Console interface can be adopted.
[0037] The data connection interface is used as a USB interface or a network interface. When the data connection interface is used as a USB interface, it is used to transmit USB physical level signals, and when it is used as a network interface, it is used to transmit network data.
[0038] In this embodiment, the data interface adopts the shape of a network interface, which can be used as a USB interface to meet the transmission of USB physical level signals, or can be used as a network interface to meet the transmission of network data, and the interface will not be easily loosened.
Embodiment 2
[0040] A data connection interface has an appearance of a network interface; specifically, the appearance of the network interface in this embodiment may be an appearance of an RJ45 interface. Alternatively, the appearance of network interfaces such as RJ-11 interface, SC optical fiber interface, FDDI interface, AUI interface, BNC interface, and Console interface can be adopted.
[0041] The data connection interface is simultaneously used as a USB interface or a network interface to transmit USB physical level signals and network data.
[0042] In this embodiment, the data interface adopts the shape of a network interface, which can be used as a USB interface or a network interface to meet the transmission of USB physical level signals and network data, and at the same time, the interface will not be easily loosened.
Embodiment 3
[0044] A data acquisition device 1, such as figure 1 As shown, the data acquisition device 1 includes: a first data connection interface 11 and a data conversion module 12, and the data conversion module 12 includes a second data connection interface 121 and a first interface 122;
[0045] Both the first data connection interface 11 and the second data connection interface 121 are data connection interfaces as described in Embodiment 1, and the first interface 122 is used to connect external devices;
[0046] The first data connection interface 11 and the second data connection interface 121 are connected by a network line, and the network line is used to transmit USB between the first data connection interface 11 and the second data connection interface 121. physical level signal;
[0047] The data conversion module 12 is used for performing mutual conversion between the USB physical level signal and the signal of the first interface 122 .
[0048] In this embodiment, the d...
