That is, in the embodiment of the present invention, the first circuit board 10 and the second circuit board 20 are disposed in the housing 100, the control module 11 and the first radio frequency module 12 are integrated on the first circuit board 10, and the second radio frequency module 21 is integrated on the second circuit board 20, which is equivalent to integrating the two circuit boards in one housing 100, so that the data exchange device provided in the embodiment of the present invention can implement two functions, that is, data transmission can be performed through the first radio frequency module 12 and the second radio frequency module 21, the rail vehicle can implement different functions through the control module 11, and more devices are not used on the rail vehicle, so that the internal space of the rail vehicle can be saved, and the space utilization rate of the rail vehicle can be improved.
It should be noted that, in the embodiment of the present invention, both the first rf module 12 and the second rf module 21 may be rf chips. The radio frequency chip refers to an electronic component which converts radio signal communication into a certain radio signal waveform and sends the radio signal waveform out through antenna resonance. In addition, in the embodiment of the present invention, the control module 11 may be a chip having a control function.

When the functional interface comprises a broadcast interface, a data interface, a debugging interface and a master control interface, at the moment, the broadcast can be connected through the broadcast interface, so that after the broadcast is connected to the data exchange device, the data exchange device can transmit data to the broadcast, so that the broadcast can broadcast the data transmitted by the data exchange device, and the debugging piece can also be connected to the data exchange device, so that the data exchange device can be debugged through the debugging piece, the control device can also be connected with the data exchange device, so that the data exchange can send data to the control device, and the control device can correspondingly control the rail vehicle according to the data sent by the data exchange device.
It should be noted that, when the control module 11 is a chip, the broadcast interface, the data interface, the debug interface, and the main control interface may all be different pins on the chip.
In addition, in some embodiments, the data exchange device may further include a first combiner 30 and a second combiner 40, both the first combiner 30 and the second combiner 40 being located in the case 100. The first rf module 12 includes a first main-set interface and a first diversity interface, the second rf module 21 includes a second main-set interface and a second diversity interface, the first combiner 30 is provided with a first main interface, a second main interface and a main-set antenna 50 interface, and the second combiner 40 is provided with a first diversity interface, a second diversity interface and a diversity antenna 60 interface.

Since the first main set interface of the first rf module 12 is electrically connected to the first main interface of the first combiner 30, and the second main set interface of the second rf module 21 is electrically connected to the second main interface of the first combiner 30, the first combiner 30 is equivalent to combining the frequencies of the first rf module 12 and the second rf module 21, and the first combiner 30 has an interface of the main set antenna 50, so that when the main set antenna 50 is interfaced with the main set antenna 50, the first rf module 12 and the second rf module 21 can perform signal transmission through the main set antenna 50. Similarly, since the first diversity interface of the first rf module 12 is electrically connected to the first diversity interface of the second combiner 40, and the second diversity interface of the second rf module 21 is connected to the second diversity interface of the second combiner 40, the second combiner 40 is equivalent to combining the frequencies of the first rf module 12 and the second rf module 21, and the second combiner 40 has an interface of the diversity antenna 60, so that when the diversity antenna 60 is interfaced with the diversity antenna 60, the first rf module 12 and the second rf module 21 can perform signal transmission through the diversity antenna 60. That is, by providing the first and second combiners 30 and 40, after the first and second combiners 30 and 40 connect the main and diversity antennas 50 and 60, the first and second rf modules 12 and 21 may perform signal transmission through the first and second combiners 30 and 40.

In addition, in the embodiment of the present invention, the combiner may be a same-frequency combiner. Specifically, the same-frequency combiner can be a 3dB electric bridge, wherein 3dB is a passive device, and can continuously sample transmission power in a certain determined direction of a transmission line, and can divide an input signal into two signals which are mutually equal in amplitude and have a phase difference of 90 degrees, so that the same-frequency combiner is mainly used for multi-signal combining, and the utilization rate of an output signal is improved. In addition, the 3dB bridge is a four-port network which is divided into 90-degree and 180-degree. The output port of the 3dB bridge can be set at will, and the 3dB bridge has two inlets and one outlet, one inlet and two outlets and two inlets and two outlets. When the 3dB electric bridge is used as a same-frequency combiner, the two-input one-output is adopted. The 3dB electric bridge can output two signals with equal amplitude, and the two paths of wireless signals share the antenna system, so that the wireless receiving performance indexes of the two radio frequency modules are very close, and the workload and the difficulty of network debugging and optimization in the middle and later periods of the rail vehicle are greatly reduced.
Additionally, in some embodiments, a connection interface may be provided on the housing 100. The connecting interface is electrically connected with the functional interface and is used for connecting a lead so as to enable the functional interface to realize corresponding functions.
When the connecting interface is arranged on the casing 100, at this time, the connecting interface can be electrically connected with the functional interface, so that the connecting interface is connected with the connecting wire, namely, one end of the connecting wire is connected to the connecting interface, and the other end of the connecting interface is connected to the corresponding equipment, so that the functional interface can transmit signals between the corresponding equipment through the connecting interface and the connecting wire, and the corresponding function can be realized by the functional interface.
It should be noted that the number of the connection interfaces may be equal to the number of the function interfaces, for example, when the number of the function interfaces is 4, the number of the connection interfaces is 4. Of course, the number of the connection interfaces may be greater than the number of the function interfaces, and the embodiment of the present invention is not limited herein.
Additionally, in some embodiments, the data exchange device may further include a first power source and a second power source. The first power source and the second power source are both located in the casing 100, and the first power source is electrically connected to the first circuit board 10 and the second circuit board 20, respectively, and the second power source is electrically connected to the first circuit board 10 and the second circuit board 20, respectively. The first power supply is used to supply power to the first circuit board 10 and the second circuit board 20, and the second power supply is used to supply power to the first circuit board 10 and the second circuit board 20.

In addition, by arranging the first power supply and the second power supply, when the first power supply fails, the second power supply can still provide electric energy for the first circuit board 10 and the second circuit board 20, so that the data exchange equipment can be more conveniently used.
Additionally, in some embodiments, a first control switch and a second control switch are disposed on the housing 100.
