Description
Technical Field
The invention relates to the field of Internet of things and intelligent fire control, in particular to an intelligent hydrant network time synchronization method and device, computing equipment and a computer storage medium.
Background
The intelligent fire hydrant needs to upload state data information of the fire hydrant to a cloud server, such as flow, water pressure, temperature and the like, and meanwhile, the time stamp generated by the data needs to be uploaded, so that the cloud server can conveniently analyze and sort the data. Therefore, the time stamp must be accurate, that is, the intelligent fire hydrant needs to have a network time synchronization function.
One common network time synchronization method is a NITZ time synchronization method (called network identifier and time zone), which provides a mechanism for providing local date, time zone, summer offset and network provider identity information to a mobile device through a wireless network, and is used for automatically updating system time by a mobile phone. The NITZ technology has become one of the selectable parts of the official standards starting from the GSM phase 2Release96 version. Another common network time synchronization method is NTP time synchronization (NetworkTime Protocol, called network time protocol), which is an application layer protocol in the TCP/IP protocol family, used to synchronize clocks between a client and a server, providing high-precision time correction. The NTP server receives the precise coordinated universal time UTC from a rights clock source (e.g., atomic clock, GPS), and the client requests and receives the time from the server. The NTP transmits based on UDP messages using a UDP port number of 123.
Neither the NITZ time synchronization nor the NTP time synchronization has an unavailable network environment, resulting in an inability to synchronize time. Wherein for the NITZ time synchronization approach not all base stations support NITZ, base stations of different providers and operators may have different sets of functions depending on the hardware and software functions of the base stations. For the NTP time synchronization method, the NTP server is not guaranteed to be available all the time, and the time spent by the NTP protocol flow is long.

Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 shows a flow diagram of an intelligent hydrant network time synchronization method according to an embodiment of the present invention. The method integrates a plurality of network time synchronization methods in the intelligent hydrant network time synchronization flow.
To more clearly describe the network time synchronization method in the method, a method for intelligent hydrant network time synchronization in the prior art is first described.
The existing intelligent hydrant technical scheme uses NITZ or NTP for network time synchronization, as shown in fig. 2, the flow is approximately as follows:
step one, the intelligent hydrant is powered on and started. After the intelligent fire hydrant is powered on and started, the internet of things module is opened every day at regular time to acquire network time, and in general, the network time can be set to be early morning, and other time can be configured. The period of acquiring the network time can be configured, for example, one day or two days, depending on the RTC time precision of the intelligent hydrant chip and the requirement of the time precision, if the time precision is high, for example, the error of every 24 hours is within 1 second, the period of acquiring the network time can be properly improved.
And step two, connecting a network. After the internet of things module is started, firstly, network connection actions can be performed, which may include a plurality of steps such as network searching, network injection, dialing, server connection and the like, if the network injection is successful or the dialing is successful, if the network injection is in a NITZ time synchronization mode, the network connection process is required to be correctly dialed and the network connection process can be realized by connecting the NTP server.
And step three, judging whether the network is successfully connected, if the network is failed to be connected, automatically removing retry, and setting the maximum retry times. The maximum retry number is configurable, and is too large depending on specific project requirements, and in an extreme network situation, the internet of things module can be opened for a long time, so that the power consumption of the intelligent hydrant can be increased. In general, the maximum number of times is set to 3. If the network is successfully connected, time synchronization is started.
And step four, performing time synchronization by using an NITZ or NTP time synchronization transmission mode. For the NITZ time synchronization mode, only interaction with the base station is required. For the NTP time synchronization mode, the data packet needs to be sent according to the NTP protocol. If the synchronization fails, the retry is also removed, and a maximum number of retries is set, typically, this value is set to 3.
And fifthly, judging whether the time synchronization is successful. If the time synchronization is successful, the local time is updated, then the Internet of things module is closed and enters a sleep mode, and the next time synchronization flow is waited. If the time synchronization connection fails and reaches the maximum retry number, or if the time synchronization fails and reaches the maximum retry number, the internet of things module is closed and enters a sleep mode, and the next time synchronization flow is waited.
The two network time synchronization modes have different technical problems, specifically:
for the NITZ time synchronization mode, there is a problem in that not all base stations support the NITZ time synchronization mode, depending on hardware and software functions of the base stations. Base stations of different providers and operators may have different sets of functions. Some newer base station devices may support the NITZ time synchronization mode, while some older devices may not. Furthermore, operators in a particular region may choose not to use NITZ time synchronization, but to synchronize the time of the mobile device in other ways. Thus, whether a base station supports NITZ time synchronization may vary from region to region and from operator to operator.
For the NTP time synchronization approach, a reliable NTP server needs to be selected, and the reliable server needs to satisfy two conditions: (1) the time precision is required to meet the requirement; (2) The service is stable and reliable, and accidents such as downtime, service stopping and the like can not occur. Open NTP servers, such as pool.ntp.org, which is a large virtual cluster time server, may be used, maintained by open source volunteers. Also, NTP servers provided by large-scale science and technology companies or national institutions may be used. However, whichever NTP server is used, the following problems exist: (1) The server can not be ensured to be available all the time by using an open source server, for example, the server is down or the server cannot be processed due to overlarge concurrency number; (2) In some network environments, the selected NTP server may not be accessible; (3) The NTP protocol flow takes longer than the NITZ time synchronization approach.
Therefore, the above-mentioned NITZ and NTP time synchronization method or technical scheme mainly has the following problems: (1) reliability is not high. Whether in NITZ or NTP time synchronization mode, there is an unavailable network environment, which results in the failure to synchronize time; (2) the speed of using NTP synchronized time scheme is slow.
Next, a method for synchronizing the network time of the intelligent fire hydrant according to an embodiment of the present invention, such as a flowchart of the method for synchronizing the network time of the intelligent fire hydrant shown in fig. 1, includes the following steps:
step S101, aiming at any intelligent fire hydrant, starting an Internet of things module according to preset synchronous time, and acquiring network time by fusing various network time synchronous methods.
In order to improve the reliability of network time synchronization of the intelligent fire hydrant and ensure the speed of network time synchronization on the basis of the reliability, in the embodiment, based on the characteristics of network environment, stability, synchronization speed, base station equipment and the like of the traditional various network time synchronization modes, various network time synchronization methods are integrated to acquire network time. Specifically, for any intelligent fire hydrant, the internet of things module is started according to preset synchronization time (such as 1 am every day), and network time is obtained by fusing various network time synchronization methods.
In an optional manner, the acquiring the network time by fusing the multiple network time synchronization methods further includes:
and according to the function set of the base station, the network time is acquired by fusing the NITZ time synchronization mode and the NTP time synchronization mode.
In an optional manner, the fusing the NITZ time synchronization manner and the NTP time synchronization manner to obtain the network time according to the function set of the base station further includes:
acquiring network time by using an NITZ time synchronization mode preferentially, and returning to a function set of the base station;
judging whether the function set of the base station supports the NITZ time synchronization mode, and if not, selecting the NTP time synchronization mode to acquire network time.
Since the speed of the NITZ synchronization time is superior to that of the NTP synchronization time, and only the base stations in a partial area do not support the NITZ time synchronization mode, the network time is synchronized by preferentially using the NITZ time synchronization mode. If NITZ synchronization time is used, the base station returns no support, and the NTP mode is selected to synchronize time.
In an optional manner, the NTP time synchronization manner to obtain the network time further includes:
presetting an alternative cname domain name for resolving an available first NTP time server;
and the NTP time synchronization mode acquires network time through a second NTP time server, and acquires network time through the alternative cname domain name when the second NTP time server is inaccessible.
In an optional manner, the number of the first NTP time server and the second NTP time server is a plurality, and the NTP time synchronization manner of obtaining the network time through the second NTP time server further includes:
for any intelligent fire hydrant, sequentially and circularly requesting the second NTP time server and the alternative cname domain name in the NTP time synchronization mode, and recording the retry request times;
judging whether the number of retries of the request reaches a preset maximum number of retries, if the number of retries does not reach the preset maximum number of retries, when the network time is successfully acquired, exiting the circulation request, and synchronizing the network time of the intelligent hydrant;
if the preset maximum retry times are reached, executing step S3, closing the Internet of things module of the intelligent fire hydrant, entering a sleep mode, and waiting for the next preset synchronization time of the intelligent fire hydrant.
In this embodiment, in order to improve the reliability of the intelligent hydrant network time synchronization, when the NTP time synchronization mode is used, for example, three large NTP time servers (called second NTP time servers) are selected, and meanwhile, more than one alternative cname domain name is preset, and the domain name can be resolved into any other available NTP time server (called first NTP time server) at will, and the first NTP time server can be operated by operation staff of the intelligent hydrant. That is, the intelligent fire hydrant is a universal NTP time server, and any specific NTP server is down or inaccessible, so that the time synchronization function of the intelligent fire hydrant is not affected, and the reliability of the time synchronization function is greatly improved.
Step S102, synchronizing the time of the intelligent fire hydrant according to the acquired network time.
And updating the local time of the intelligent fire hydrant according to the acquired network time.
And step S103, closing the Internet of things module of the intelligent fire hydrant, entering a sleep mode, and waiting for the execution of the next preset synchronization time until the network time is acquired.
And closing the internet of things module of the intelligent fire hydrant, entering a sleep mode, waiting for the next time synchronization flow, and executing the step S101 until the network time is acquired.
According to the scheme provided by the embodiment of the invention, in the network time synchronization process of the intelligent hydrant, the NITZ time synchronization mode and the NTP time synchronization mode are fused, and the cname technology is added. Compared with the traditional intelligent hydrant network time synchronization method, the network time synchronization method greatly improves the reliability of network time synchronization and ensures the speed of network time synchronization on the basis.
Fig. 3 shows a flow diagram of a method for intelligent hydrant network time synchronization according to another embodiment of the present invention. The method adds NITZ blacklist mechanism, and adds a base station into the NITZ blacklist when confirming that the base station does not support NITZ function. And cycling through the attempts of the plurality of NTP servers and the cname server by setting a maximum number of retries. Specifically, as shown in fig. 3, the method comprises the following steps:
step S301, determining whether the network connection is successful.
The intelligent fire hydrant is powered on and started, for example, the internet of things module is automatically started every morning, and the internet of things module is connected with a network after being started. Judging whether the network connection is successful, if so, executing step S302, namely judging whether the connected base station is in the NITZ blacklist; if the network connection is unsuccessful, further judging whether the maximum retry times are reached, if the maximum retry times are reached, executing step S311, namely closing the Internet of things module, and entering a sleep mode; if the maximum retry number is not reached, the network connection is continued.
In step S302, it is determined whether the connected base station is in the NITZ blacklist.
In an optional mode, judging whether a function set of the base station supports a NITZ time synchronization mode, and if not, adding the base station into a NITZ blacklist;
for any intelligent fire hydrant, after the next net injection is successful, judging whether the requested base station is in the NITZ blacklist, and if so, not trying the NITZ time synchronization mode.
In this embodiment, a NITZ blacklist mechanism is added, and when a certain base station is confirmed not to support the NITZ function, the base station is added to the NITZ blacklist. However, after the next successful network injection, if a device in the blacklist is connected, it is not necessary to try the NITZ time synchronization mode any more, because the base station does not support the NITZ time synchronization mode, and it is ineffective to try again many times. If the connected base station is not in the NITZ blacklist, step S308 is performed, i.e. time synchronization is performed using the NTP server.
In step S303, time synchronization is performed using NITZ.
Time synchronization is performed using NITZ, if synchronization is successful, the local time is updated, and if synchronization is unsuccessful, step S306 is performed, i.e. it is determined whether the base station supports NITZ.
Step S304, judging whether the synchronization is successful.
Step S305, determining whether the maximum retry number is reached.
If the retry is performed several times and the maximum retry number is reached, and the synchronization time is not successful, step S308 is performed, i.e. the NTP server is used for time synchronization.
In step S306, it is determined whether the base station supports NITZ.
In an optional mode, judging whether the function set of the base station supports an NITZ time synchronization mode, if so, switching to the NTP time synchronization mode to acquire network time when the number of retries requested by the intelligent fire hydrant reaches a preset maximum number of retries.
In an optional mode, judging whether a function set of the base station supports a NITZ time synchronization mode, and if not, adding the base station into a NITZ blacklist;
for any intelligent fire hydrant, after the next net injection is successful, judging whether the requested base station is in the NITZ blacklist, and if so, not trying the NITZ time synchronization mode.
Specifically, it is determined whether the base station supports NITZ, if the base station supports the NITZ synchronization mode, step S305 is executed, and it is determined whether the maximum retry number is reached; if the base station does not support the NITZ synchronization mode, step S307 is performed, i.e., the base station is added to the NITZ blacklist.
In step S307, the base station is added to the NITZ blacklist.
For example, the base station ID is added to the NITZ blacklist.
In step S308, time synchronization is performed using the NTP server.
After switching to the NTP time synchronization mode, the maximum retry number is also set. Every time the 1 st NTP server, the 2 nd NTP server, the 3 rd NTP server and the cname server are tried gradually, any server can exit the cycle in advance after the synchronization time is successful, then the local time is updated, the Internet of things module is closed, and the sleep mode is entered. The network time synchronization reliability is greatly improved by cycling the requests in an NTP time synchronization mode.
Step S309, a cname server is set.
For example, it is the responsibility of the operator of the intelligent hydrant to set any other available NTP time server and set the cname domain name.
Step S3010, determine whether synchronization is successful.
Step S3011, the Internet of things module is closed, and a sleep mode is entered.
And closing the internet of things module of the intelligent fire hydrant, entering a sleep mode, and waiting for the next preset synchronization time of the intelligent fire hydrant.
The proposal provided by the embodiment of the invention increases the NITZ blacklist mechanism, avoids invalid attempts and further improves the speed of network time synchronization. And cycling through the attempts of the plurality of NTP servers and the cname server by setting a maximum number of retries. The invention can ensure the successful synchronization to the maximum extent under the extreme condition that the base station which does not support NITZ or the NITZ fails to synchronize even NTP time synchronization fails, further improves the reliability of network time synchronization and takes account of the reliability of network time synchronization and the speed of synchronization time.
