Step S1: the stator 11 and the rotor 12 are connected in wireless communication through the communication chip 110.
In an embodiment, the stator 11 and the rotor 12 in the slip ring 1 are respectively provided with the communication chip 110, so that the stator 11 and the rotor 12 can establish wireless communication through the communication chip 110, thereby transmitting information, and specifically, for the arrangement manner of the communication chip 110 in the stator 11 and the rotor 12, please refer to the description in the slip ring 1 provided in the first embodiment of the present invention, which is not repeated herein. Among the wireless communication technologies, there may be included, but not limited to: global System for Mobile Communication (GSM), Enhanced Mobile Communication (EDGE), wideband Code division multiple Access (W-CDMA), Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), bluetooth, Wireless Fidelity (WiFi) (e.g., IEEE802.11 a, IEEE802.11b, IEEE802.1 g, and/or IEEE802.11 n), Voice over internet protocol (VoIP), Worldwide Interoperability for Microwave Access (Wi-Max), other suitable protocols for instant messaging and instant messaging, and any other suitable protocols, including those that have not yet been developed.
In one embodiment, at step S1: the step of wirelessly communicating the stator 11 and the rotor 12 via the communication chip 110 includes: and communication connection is realized through a wireless millimeter wave technology.
In one embodiment, that is to say the communication chip 110, the connection is preferably made by wireless millimeter wave technology. The millimeter wave frequency band here typically means a frequency range of 30GHz to 300GHz, a corresponding wavelength of 1 mm to 10 mm, and a wider bandwidth is provided, so that high-speed and stable transmission of data can be realized. Compared with wireless communication technologies such as WiFi, Bluetooth and UWB in the prior art, the method can greatly reduce the possibility of wireless signal crosstalk, thereby ensuring the stability and reliability in the effective data transmission process.
Step S2: the stator 11 and the rotor 12 transmit communication signals therebetween through the communication chip 110.
In one embodiment, it is understood that, since the communication connection is established, the signal can be wirelessly transmitted between the stator 11 and the rotor 12 through the communication chip 110. In one embodiment, the communication chips 110 are preferably connected by wireless millimeter wave technology, and by using the characteristics of the wireless millimeter wave technology, the beneficial effects of high speed, stability and high interference resistance of data transmission can be achieved.
In one embodiment, at step S2: the step of transmitting the communication signal between the stator 11 and the rotor 12 through the communication chip 110 includes: the communication chip 110 performs serialization and/or deserialization processing of signals when transmitting communication signals through the serialization deserialization module.
In an embodiment, the communication chip 110 is provided with a deserializing module, which can serialize a plurality of signals to be transmitted into one signal at a transmitting end, and deserialize the plurality of signals at a receiving end to obtain the original plurality of signals, thereby improving the transmission rate and stability.
In one embodiment, the step of performing serialization and/or deserialization of the communication signal when transmitting the communication signal comprises: the first communication chip 1101 acquires a signal to be transmitted, acquires a serial differential signal through serialization processing, and transmits the serial differential signal to the second communication chip 1102; after the second communication chip 1102 receives the serial differential signal, the serial differential signal is deserialized to obtain a plurality of paths of signals.
In one embodiment, as described above, the first communication chip 1101 is a transmitting end with respect to the second communication chip 1102, but may be a transmitting chip directly, and the second communication chip 1102 is a receiving chip. Therefore, for the embodiment in which the first communication chip 1101 is a chip relative to the transmitting end of the second communication chip 1102, the communication chip 110 may perform the serialization processing and/or the deserialization processing at the same time, and the first and the second are only used for distinguishing the receiving end from the transmitting end, and are not used for actually distinguishing the two communication chips; in the latter embodiment, only the first communication chip 1101 performs serialization processing, and the second communication chip 1102 performs deserialization processing. Therefore, multi-channel signals are transmitted in one-channel signal transmission, and the speed and the stability of signal transmission are improved.
In one embodiment, the step of performing serialization and/or deserialization of the communication signal when transmitting the communication signal comprises: the first communication chip 1101 acquires serial rate information at the time of serialization processing, and transmits the serial rate information to the second communication chip 1102 before transmitting a serial differential signal; the second communication chip 1102 acquires the serial rate information and performs deserialization processing according to the serial rate information.
In one embodiment, it is appreciated that the second communication chip 1102 needs to know the rate at which the serialized data is to be able to receive and correctly perform the deserialization operation. Therefore, before the first communication chip 1101 sends valid data, a code (for example, 1010101010 … …) that is convenient for the second communication chip 1102 to perform rate detection, that is, serial rate information, may be sent first, and after receiving, the second communication chip 1102 performs rate locking using the code, and correct data transmission may be performed after locking, thereby ensuring stability of data transmission. The timing of sending the rate detection code may be selected when the system is powered on or when it is detected that the sending and receiving are interconnected, which is specific to the system design and is not limited herein.
A slip ring signal transmission method according to a second embodiment of the present invention includes the steps of: step S1: the stator 11 and the rotor 12 are in wireless communication connection through the communication chip 110; step S2: the stator 11 and the rotor 12 transmit communication signals therebetween through the communication chip 110. Therefore, the invention can realize the non-contact wireless high-speed signal transmission in the slip ring and simultaneously reduce the mechanical design difficulty and size of the slip ring. In addition, further, the slip ring signal transmission method provided by the embodiment of the invention can also realize high speed, low delay and high anti-interference performance through a wireless millimeter wave communication technology, and greatly improve the efficiency and quality of signal transmission; meanwhile, as the communication chip 110 for transmitting signals is provided with the serial deserializing module, multiple paths of signals can be transmitted in series, so that the transmission rate of the transmission model is improved, a section of code which is convenient for a receiving chip to carry out rate detection is sent before effective data is sent, the receiving chip utilizes the code to lock the rate, correct data transmission can be carried out after the rate is locked, and the stability of signal transmission is improved. In addition, due to the adoption of a non-contact communication transmission mode, the signal transmission is not influenced by mechanical loss, the service life of a product is prolonged, the maintenance difficulty is reduced, the operation of a user is reduced, the convenience of the user is increased, and the use experience of the user is improved. In addition, due to the fact that wireless high-speed stable signal transmission of the slip ring is achieved, application scenes and practicability of the slip ring are increased, and the market and the use field are expanded.
Third embodiment
Fig. 3 is a schematic flow chart of a slip ring signal transmission method according to a third embodiment of the present invention. For a clear description of the slip ring signal transmission method provided by the third embodiment of the present invention, please refer to fig. 1, 2 and 3.
As can be seen from the description of the slip ring signal transmission method provided in the second embodiment, in order to correctly perform the deserialization process, the rate of the serialized data needs to be known. The prior art method is to tell the chip performing the deserialization process the rate at which data is to be transmitted next by configuration prior to data transmission. Since the receiving chip is usually in a passive receiving position, in some scenarios, the receiving chip cannot know the rate at which data is to be transmitted. It is difficult for the receiving chip to detect the transmission rate of data from the normal data stream, especially when the range of possible transmission rates is large, which is not realized. In view of the above, a slip ring signal transmission method according to a third embodiment of the present invention is provided, which specifically includes the following steps:
step S21: the first communication chip 1101 acquires the band transmission signal, and acquires the serial rate information and the serial differential signal by serialization processing.
In one embodiment, the relationship between the first communication chip 1101 and the second communication chip 1102 has been described in the foregoing, and is not described herein again. For the transmission signal acquired by the first communication chip 1101, since it is to be used for performing serialization processing, it is preferable that multiple signals, specifically, it may include but is not limited to LVDS (Low-Voltage Differential Signaling), single-ended CMOS (complementary metal oxide semiconductor), and the multiple transmission signals are processed into one path of serial Differential signal through serialization processing of the serial deserializer module. Furthermore, the acquisition of the serial rate information may include, but is not limited to, acquisition in a configuration module of the device; the acquisition may also be performed by a serialization deserialization module when performing serialization processing.
Step S22: the first communication chip 1101 sends serialization rate information to the second communication chip 1102.
Step S23: the first communication chip 1101 transmits a serial differential signal to the second communication chip 1102.
In an embodiment, the step S22 and the step S23 are separately distinguished, and are used to embody that before the serial differential signal of the one or more signal sets is transmitted, that is, before the valid data is transmitted, a piece of code facilitating the rate detection of the second communication chip 1102 is transmitted, that is, the rate information is serialized. After the second communication chip 1102 receives the serialized rate information, it sends serial differential signals of valid data.
Step S24: the second communication chip 1102 receives the serialization rate information and the serial differential signal, performs deserialization processing according to the serialization rate information, and obtains a plurality of signals from the serial differential signal.
In one embodiment, the second communication chip 1102 firstly receives the serialization rate information, locks the processing rate of the deserializing process, and executes the deserializing process after receiving the serial differential signal, so that the deserializing process can be performed at a correct rate to restore the transmitted serial differential signal to the previous multiple transmission signals, that is, to obtain multiple signals. Furthermore, in another embodiment, when the serial differential signal is received without correctly receiving the serialization rate information, the second communication chip 1102 may also obtain the default preset serialization rate information from its configuration module, so as to lock the deserializing rate as a standby scheme, thereby ensuring that the signal recovery can be correctly completed.
A slip ring signal transmission method according to a second embodiment of the present invention includes the steps of: step S21: the first communication chip 1101 acquires a band transmission signal, and acquires serial rate information and a serial differential signal through serialization processing; step S22: the first communication chip 1101 sends serialization rate information to the second communication chip 1102; step S23: the first communication chip 1101 transmits a serial differential signal to the second communication chip 1102; step S24: the second communication chip 1102 receives the serialization rate information and the serial differential signal, performs deserialization processing according to the serialization rate information, and obtains a plurality of signals from the serial differential signal. Therefore, the invention can save the link of informing the receiving chip of the transmission rate in advance, enhance the self-adaptability of the system design, simplify the system design and ensure the stability and reliability of data transmission. Through the deserializing operation, the transmission of multiple signals is realized, and the transmission of the multiple signals can effectively reduce the signal connection quantity between the sending end and the receiving end, thereby improving the data transmission rate and realizing the transmission of high-speed data.
