Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of time synchronization, and particularly relates to a time synchronization method, device and equipment and a storage medium. BACKGROUND

[0002] At present, high-precision time synchronization is crucial to the development of various industries. Specifically, high-precision time synchronization can be achieved by the following two methods: 1. Real-time solving of the clock error of the receiver local clock through a precise point positioning model with coordinate constraints, and then eliminating the hardware delay between the signal transmitter and the global navigation satellite system (GNSS) receiver through a calibration hardware delay method, so as to realize precise time synchronization of a single pseudolite system and a GNSS system. 2. Starting from the time transfer base station, time transfer is performed on each collection substation in turn until the clock error calculation of the feedback base station is completed and compared with the threshold value, and then returned to the time transfer base station; then starting from the feedback base station, time transfer is performed on each collection substation in reverse, and then returning to the time transfer base station and calculating the clock error of the time transfer base station and comparing it with the threshold value to complete the time transfer.

[0003] However, the first method can only solve the time synchronization problem of a single pseudolite system through a specific constraint algorithm model, and cannot be applied to large-capacity device scenarios. At the same time, the second method needs to set a specific threshold value, which has poor scene migration and cannot be applied to large-capacity device scenarios. Therefore, how to realize high-precision time synchronization in a large-capacity device scenario is a technical problem to be solved. SUMMARY

[0004] The present application provides a time synchronization method, device, equipment and storage medium to realize high-precision time synchronization in a large-capacity device scenario. The technical solution of the present application is as follows:

[0006] In a possible implementation, the method further includes: sending a broadcast signal; the broadcast signal is used to determine whether the user equipment is online; in response to an online confirmation message sent by the user equipment through the first communication module, sending a synchronization package message to the user equipment through the first communication module; the synchronization package message is used to confirm whether the user equipment needs to perform time synchronization; in response to a synchronization package confirmation message sent by the user equipment, obtaining a first clock signal, a first timestamp, and a first second pulse signal from a real time clock (RTC) module, and sending the first clock signal, the first timestamp, and the first second pulse signal to the user equipment through the first communication module to perform time synchronization on the user equipment.

[0007] In a possible implementation, before the base station sends the broadcast signal, the method further includes: receiving, by a second communication module in the base station, a second clock signal, a second timestamp, and a second second pulse signal sent by a parent clock to the base station to perform time synchronization on the base station.

[0008] In a possible implementation, a network layer of the first communication module is configured based on an IEEE 802154 protocol, a 6LOPAN protocol, and an IEEE 1588 protocol, and an application layer of the first communication module is configured based on a 5G protocol or an ultra-wideband protocol; a network layer of the second communication module is configured based on the IEEE 802154 protocol, the 6LOPAN protocol, and the IEEE 1588 protocol, and an application layer of the second communication module is configured based on the 5G protocol or the ultra-wideband protocol.

[0009] In a second aspect, a time synchronization apparatus is provided, which includes a receiving unit and a sending unit; the receiving unit is configured to receive, by a first communication module in the base station, a synchronization package confirmation message sent by the user equipment; the first communication module is configured based on a 5G protocol or an ultra-wideband protocol, and the synchronization package confirmation message is used to confirm time synchronization; and the sending unit is configured to send, by the first communication module, a first clock signal, a first timestamp, and a first second pulse signal to the user equipment to perform time synchronization on the user equipment.

[0010] In a possible implementation, the apparatus further includes a processing unit; the sending unit is further configured to send a broadcast signal; the broadcast signal is used to determine whether the user equipment is online; the sending unit is further configured to, in response to an online confirmation message sent by the user equipment through the first communication module, send a synchronization package message to the user equipment through the first communication module; the synchronization package message is used to confirm whether the user equipment needs to perform time synchronization; and the processing unit is configured to, in response to a synchronization package confirmation message sent by the user equipment, acquire the first clock signal, the first timestamp, and the first second pulse signal from the RTC module, and send the first clock signal, the first timestamp, and the first second pulse signal to the user equipment through the first communication module to perform time synchronization on the user equipment.

[0011] In a possible implementation, before the base station sends the broadcast signal, the receiving unit is further configured to receive, through a second communication module in the base station, a second clock signal, a second timestamp, and a second second pulse signal sent by a parent clock to the base station to perform time synchronization on the base station.

[0012] In a possible implementation, a network layer of the first communication module is configured based on an IEEE 802.154 protocol, a 6LOPAN protocol, and an IEEE 1588 protocol, and an application layer of the first communication module is configured based on a 5G protocol or an ultra-wideband protocol; a network layer of the second communication module is configured based on the IEEE 802.154 protocol, the 6LOPAN protocol, and the IEEE 1588 protocol, and an application layer of the second communication module is configured based on the 5G protocol or the ultra-wideband protocol.

[0016] The first aspect provided by the application brings at least the following beneficial effects: in the prior art, the time synchronization problem of a single pseudolite system is usually solved by a specific constraint algorithm model, or each acquisition substation is time-synchronized in turn from a time-synchronization base station until the clock deviation calculation of the feedback base station is completed and compared with a threshold value and then returned to the time-synchronization base station. However, neither of the two methods can be applied to a large-capacity device scenario and cannot meet the industrial demand. After receiving the synchronization packet confirmation message sent by the user equipment, the first communication module is configured based on the 5G protocol or the ultra-wideband protocol, and the first clock signal, the first timestamp, and the first second pulse signal are sent to the user equipment to synchronize the time of the user equipment. The first communication module is configured based on the 5G protocol or the ultra-wideband protocol. Since the transmission data speed of the first communication module configured based on the 5G protocol or the ultra-wideband protocol is fast, the clock delay of the clock signal transmitted through the first communication module is low, thereby enabling the user equipment to achieve high-precision time synchronization. At the same time, the first communication module wirelessly connects the user equipment, and a large number of user equipment can be connected, thereby realizing high-precision time synchronization in a large-capacity device scenario.

[0017] It should be noted that the technical effects brought by any one of the implementation manners of the second aspect to the fifth aspect can be referred to the technical effects brought by the corresponding implementation manners in the first aspect, which will not be repeated here.

[0026] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0027] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0028] Before providing a detailed introduction to the time synchronization method provided in this application, let's briefly introduce the implementation environment (implementation architecture) involved in this application.

[0029] The time synchronization method provided in this application can be applied to time synchronization systems. Figure 1 A schematic diagram of one structure of this time synchronization system is shown. For example... Figure 1 As shown, the time synchronization system 10 includes a base station 11 and a user equipment (...). Figure 1 User equipment 121 and user equipment 122 are shown as examples; in actual applications, there may be more or fewer user equipment, which is not limited in this application. A master clock 13 is also shown. Base station 11 includes a first communication module 111, a second communication module 112, a device detection module 113, and an RTC module 114. The first communication module 111 is wirelessly connected to user equipment 121, user equipment 122, and device detection module 113, respectively. The second communication module 112 is wirelessly connected to master clock 13 and RTC module 114, respectively. Device detection module 113 is connected to RTC module 114.

[0030] Base station 11 is used to send a first clock signal, a first timestamp and a first second pulse signal to user equipment 121 and user equipment 122 through the first communication module 111, so as to synchronize the time of user equipment 121 and user equipment 122.

[0031] The master clock 13 is used to send a second clock signal, a second timestamp, and a second second pulse signal to the base station 11 through the second communication module 112 in order to synchronize the time of the base station 11.

[0032] The RTC module 114 is configured to save the second clock signal, the second timestamp and the second second pulse signal sent by the master clock 13 to the base station 11 through the second communication module 112 in the base station 11.

[0033] The device detection module 113 acquires the first clock signal, the first timestamp and the first second pulse signal from the RTC module 114 in response to the synchronization packet confirmation message sent by the user equipment 121 and the user equipment 122 through the first communication module 111. The device detection module 113 packages the acquired first clock signal, first timestamp and first second pulse signal, and sends them to the user equipment 121 and the user equipment 122 through the first communication module 111 to synchronize the time of the user equipment 121 and the user equipment 122.

[0034] For the convenience of understanding, the time synchronization method provided in the present application is specifically introduced below in combination with the accompanying drawings.

[0035] As shown in Figure 2 , a time synchronization method provided in an embodiment of the present application, the method comprises:

[0036] S201, the base station receives the synchronization packet confirmation message sent by the user equipment through the first communication module in the base station.

[0037] The first communication module is configured based on a 5G protocol or an ultra-wideband protocol, and the synchronization packet confirmation message is used to confirm the time synchronization.

[0038] As a possible implementation manner, the device detection module in the base station receives the synchronization packet confirmation message sent by the user equipment through the first communication module, and accesses the user equipment to the base station networking.

[0039] S202, the base station sends the first clock signal, the first timestamp and the first second pulse signal to the user equipment through the first communication module to synchronize the time of the user equipment.

[0040] As a possible implementation manner, the base station acquires the first clock signal, the first timestamp and the first second pulse signal from the RTC module for the user equipment that has accessed the base station networking, packages the first clock signal, the first timestamp and the first second pulse signal, and sends them to the user equipment through the first communication module to synchronize the time of the user equipment.

[0041] It can be understood that the prior art usually solves the time synchronization problem of a single pseudolite system through a specific constraint algorithm model, or starts from a time service base station to successively time service each collection substation until the clock bias calculation of the feedback base station is completed and compared with a threshold value and then returned to the time service base station. However, both methods cannot be applied to large-capacity equipment scenarios and cannot meet industrial needs. After receiving the synchronization packet confirmation message sent by the user equipment, the first communication module sends the first clock signal, the first timestamp, and the first second pulse signal to the user equipment to synchronize the time of the user equipment. The first communication module is configured based on the 5G protocol or the ultra-wideband protocol. Since the first communication module configured based on the 5G protocol or the ultra-wideband protocol has a fast transmission data speed, the clock delay of the clock signal transmitted through the first communication module is low, thereby enabling high-precision time synchronization for the user equipment. At the same time, the first communication module wirelessly connects the user equipment, and can connect a large number of user equipment, thereby realizing high-precision time synchronization in a large-capacity equipment scenario.

[0042] In some embodiments, in order to synchronize the time of the user equipment, as shown in Figure 3 The time synchronization method provided by the embodiments of the present application further includes:

[0043] S301, the base station sends a broadcast signal.

[0044] The broadcast signal is used to determine whether the user equipment is online.

[0045] S302, the base station sends a synchronization packet message to the user equipment through the first communication module in response to the online confirmation message sent by the user equipment through the first communication module.

[0046] The synchronization packet message is used to confirm whether the user equipment needs to be time synchronized.

[0047] As a possible implementation, after receiving the broadcast signal sent by the base station, the user equipment sends an online confirmation message to the device detection module in the base station through the first communication module.

[0048] Further, the device detection module in the base station sends a synchronization packet message to the user equipment through the first communication module in response to the online confirmation message sent by the user equipment, and the synchronization packet message includes a packet header, a packet sequence number, a packet type, a function code, and an acknowledge character (ACK).

[0049] It should be noted that the packet header can be a fixed character, the packet sequence number can be the number of communications between the user equipment and the base station, the packet type can be a broadcast packet or a request packet, the function code can include time synchronization, function query, and base station status, and the ACK can include a check code and a fixed packet trailer.

[0050] For example, after receiving the broadcast signal sent by the base station, the user equipment sends "I am here" to the device detection module in the base station through the first communication module. Further, the device detection module in the base station sends a synchronization package message to the user equipment through the first communication module in response to the "I am here" sent by the user equipment. The package header of the synchronization package message is 0X55, the package serial number is 1, the package type is a broadcast package, the function code is time synchronization, function query, and base station state, and the ACK is 0Xff.

[0051] S303, the base station acquires the first clock signal, the first timestamp, and the first second pulse signal from the RTC module in response to the synchronization package confirmation message sent by the user equipment.

[0052] As a possible implementation, after the user equipment receives the synchronization package message sent by the device detection module in the base station through the first communication module, the user equipment determines whether the received synchronization package message is sent by the base station through the package type in the synchronization package message. After determining that the received synchronization package message is sent by the base station, the user equipment sends a synchronization package confirmation message to the device detection module in the base station through the first communication module. The synchronization package confirmation message includes a package header, a package serial number, a package type, a query code, and an ACK.

[0053] Further, the device detection module in the base station acquires the first clock signal, the first timestamp, and the first second pulse signal from the RTC module in response to the synchronization package confirmation message sent by the user equipment.

[0054] It should be noted that the query code can specifically include a request for time synchronization, a request for function query, and a request for base station state.

[0055] For example, after the user equipment receives the synchronization package message sent by the device detection module in the base station through the first communication module, the user equipment determines whether the synchronization package message is sent by the base station through the package type in the synchronization package message. After determining that the received synchronization package message is sent by the base station, the user equipment sends a synchronization package confirmation message to the device detection module in the base station through the first communication module. The package header of the synchronization package confirmation message is 0X55, the package serial number is 2, the package type is a request package, the query code is a request for time synchronization, and the ACK is 0Xff.

[0056] S304, the base station sends the first clock signal, the first timestamp, and the first second pulse signal to the user equipment through the first communication module to synchronize the time of the user equipment.

[0057] As a possible implementation, the device detection module in the base station packages the acquired first clock signal, first timestamp, and first second pulse signal, and sends them to the user equipment through the first communication module.

[0058] Understandably, the online status of the user equipment is confirmed via broadcast signals. After confirming that the user equipment is online, a synchronization packet message is sent to the user equipment to confirm whether the user equipment needs to synchronize its time. Furthermore, after determining that the user equipment needs to synchronize its time, a first clock signal, a first timestamp, and a first second pulse signal are sent to the user equipment to achieve time synchronization.

[0059] In some embodiments, in order to synchronize the time of the base station, before the base station sends a broadcast signal, such as Figure 4 As shown in the embodiments of this application, the time synchronization method further includes:

[0060] S401. The base station receives the second clock signal, the second timestamp, and the second second pulse signal sent by the master clock to the base station through the second communication module in the base station, so as to synchronize the time of the base station.

[0061] One possible implementation involves manually configuring the master clock, setting the number of channels for outputting second pulse signals, the source of the second clock signal, and the frequency at which the master clock sends the second clock signal. The master clock then transmits the second clock signal, the second timestamp, and the second second pulse signal to the base station via a second communication module.

[0062] Furthermore, after receiving the second clock signal, second timestamp, and second second pulse signal sent to the base station by the master clock through the second communication module, the base station stores the second clock signal in the base station through the RTC module in the base station to synchronize the base station's time.

[0063] Simultaneously, the calibration module in the base station receives the third clock signal sent by the master clock through the second communication module and determines the difference between the third clock signal and the second clock signal stored in the RTC module of the base station. If the difference between the third clock signal and the second clock signal stored in the RTC module of the base station is greater than or equal to a preset threshold, the calibration module in the base station sends a time synchronization request message to the master clock through the second communication module. In response to the received time synchronization request message, the master clock sends the second clock signal, the second timestamp, and the second second pulse signal to the base station through the second communication module to synchronize the time of the base station.

[0064] It should be noted that the number of channels for the second pulse signal can be specifically 3, and the source of the clock signal can be either a BeiDou-2 or BeiDou-3 satellite. The time synchronization request message is used to synchronize the time of the base station.

[0065] It can be understood that the application receives the second clock signal, the second timestamp and the second second pulse signal sent by the master clock through the second communication module. The second communication module is configured based on a 5G protocol or an ultra-wideband protocol. Since the transmission speed of the second communication module configured based on the 5G protocol or the ultra-wideband protocol is fast, the clock delay of the clock signal transmitted through the second communication module is low, thereby enabling high-precision time synchronization for the base station and further ensuring the precision of subsequent time synchronization for the user equipment.

[0066] In some embodiments, the network layer of the first communication module is configured based on an IEEE802154 protocol, a 6LOPAN protocol and an IEEE1588 protocol, and the application layer of the first communication module is configured based on a 5G protocol or an ultra-wideband protocol. The network layer of the second communication module is configured based on an IEEE802154 protocol, a 6LOPAN protocol and an IEEE1588 protocol, and the application layer of the second communication module is configured based on a 5G protocol or an ultra-wideband protocol.

[0067] It can be understood that since the transmission speed of the first communication module configured based on the ultra-wideband protocol is higher than that of the first communication module configured based on the 5G protocol, the first communication module configured based on the ultra-wideband protocol can be applied to an industrial scene with high requirements for time synchronization precision. The first communication module configured based on the 5G protocol can be applied to an industrial scene with less high requirements for time synchronization precision and a large deployment area, thereby being applicable to large-capacity equipment scenes with different time synchronization precision requirements.

[0068] Figure 5 A time synchronization device 500 is shown according to an exemplary embodiment, as shown in Figure 5 The time synchronization device 500 provided by the embodiment of the application includes a receiving unit 501 and a sending unit 502.

[0069] The receiving unit 501 is configured to receive a synchronization packet confirmation message sent by a user equipment through a first communication module in a base station. The first communication module is configured based on a 5G protocol or an ultra-wideband protocol, and the synchronization packet confirmation message is used to confirm time synchronization.

[0070] The sending unit 502 is configured to send a first clock signal, a first timestamp and a first second pulse signal to the user equipment through the first communication module, so as to perform time synchronization for the user equipment.

[0071] Optionally, as shown in Figure 5 In order to perform time synchronization for the user equipment, the time synchronization device 500 provided by the embodiment of the application further includes a processing unit 503.

[0072] The sending unit 502 is further configured to send a broadcast signal. The broadcast signal is used to determine whether the user equipment is online.

[0073] The sending unit 502 is further configured to send a synchronization packet message to the user equipment through the first communication module in response to the online confirmation message sent by the user equipment through the first communication module. The synchronization packet message is used to confirm whether the user equipment needs to perform time synchronization.

[0074] The processing unit 503 is configured to acquire the first clock signal, the first timestamp and the first second pulse signal from the RTC module in response to the synchronization packet confirmation message sent by the user equipment, and send the first clock signal, the first timestamp and the first second pulse signal to the user equipment through the first communication module to perform time synchronization on the user equipment.

[0075] Optionally, as shown in Figure 5 In order to perform time synchronization on the base station, before the base station sends the broadcast signal, the receiving unit 501 provided by the embodiment of the application is further configured to:

[0076] receive the second clock signal, the second timestamp and the second second pulse signal sent by the master clock to the base station through the second communication module in the base station to perform time synchronization on the base station.
