Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a flowchart of an embodiment of a frequency statistics method of the present application. As shown in fig. 1, the statistical method for message frequency according to this embodiment is executed by a statistical device for message frequency, where the statistical device for message frequency is set in a process, and the statistical method specifically includes the following steps:
s101, recording a plurality of receiving moments of a plurality of messages in the process of receiving the plurality of messages which are sent by a message sending module which is subscribed in advance and is positioned in the same process with a frequency counting device;
and S102, counting the frequency of the message sent by the message sending module according to a plurality of receiving moments within a preset time length.
That is, the main execution body of the statistical method of the message frequency of the embodiment is a statistical device of the message frequency, and the statistical device of the message frequency and the message sending module of the frequency to be counted are arranged in the same process to count the frequency of sending messages by the message sending module in the same process.
The message frequency statistical method of the embodiment can be used for counting the frequency of sending messages by any one of any two modules with information interaction in information flow.
Optionally, the statistical apparatus for message frequency in this embodiment may be an application-integrated software module, and may also be extended to be an electronic entity, configured to monitor message sending modules in the same process in business.
In this embodiment of the present application, an independent message frequency statistics module may also be used to perform cross-process statistics on the frequency of a message in any other process, for example, if the message frequency statistics module is set in a first process, when the frequency of a message sending module in a second process is counted and a message sending module in the second process issues topic message data, the topic message data belongs to cross-process operations from the second process to the message frequency statistics module in the first process, and there is a time delay, so that the time when the message frequency statistics module in the first process records the topic message data issued by the message sending module in the second process is not accurate enough. In addition, when other modules need the frequency of the message sending module, the cross-process may also request the frequency of the message sending module in the second process from the statistical module of the message frequency in the first process, and the request itself also has a communication delay.
In order to further improve the accuracy of the message frequency statistics, in this embodiment, a statistics device of the message frequency may be set in each process to perform statistics on the frequency of the message sent by the message sending module in the same process. Because the priority of information processing in the same process is the highest and is far greater than the information communication across processes, the time delay can be effectively shortened, and the accuracy of frequency statistics is improved.
Specifically, in this embodiment, the message of the message sending module in the same process needs to be subscribed in advance, so that the statistical device of the message frequency can receive the subscribed message only when the message sending module sends the message, and thus the receiving time of the message can be recorded. That is, although the statistical apparatus of the message frequency in this embodiment subscribes to the message of the message sending module in the same process, the statistical apparatus does not store the message of the message sending module, and records only the receiving time when the message sent by the message sending module is received.
In addition, in this embodiment, taking the duration used for statistics as the preset time length as an example, the statistical device of the message frequency records a plurality of receiving times of a plurality of messages during the process of receiving a plurality of messages sent by the message sending module subscribed in advance and located in the same process within the preset time length, that is, each message corresponds to one receiving time. In the same process, the time difference between the receiving time of each message received by the message frequency counting device and the sending time of the message sent by the message sending module is very small, so in this embodiment, the frequency of the message sent by the message sending module can be counted according to a plurality of receiving times of a plurality of messages sent by the message sending module within a preset time length. For example, the number of messages sent within a preset time period may be divided by the preset time period, so as to obtain the frequency of sending the messages by the corresponding message sending module.
The preset time length of the embodiment may be set according to the specific scene requirement in the practical application. For example, it may be 30s, 1min, or other length of time. For example, in a scenario where the frequency requirement is not accurate, a longer preset time length may be set, and in a scenario where the frequency requirement is very accurate, a relatively shorter preset time length may be set.
Optionally, a message management module is arranged outside the processes, and is configured to manage the message sending modules in the processes, and specifically record information of the message sending modules in the processes. In practical applications, the message management module may subscribe to the message of the message sending module, for example, the ID of the process where the current frequency statistics apparatus is located is "10", and the message management module may subscribe to the message of the message sending module where the ID of the process is "10". In a specific implementation, the statistical device of the message frequency may determine, according to the process identifier of the process, a module identifier of the message sending module to be subscribed, and then send, to the detailed management module, a subscription request for the message sent by the message sending module, that is, the subscription request carries the identifier of the message sending module. Thus, the message management module establishes the subscription relationship between the statistical device of the message frequency and the message sending module in the same process, and notifies the message sending module in the same process that the statistical device of the message frequency subscribes the message. Thus, when the message sending module in the same process sends message data, the message data is sent to the sending end, and also needs to be sent to the frequency statistics device according to the subscription relationship. The statistical device of the message frequency can receive and timely record the receiving time of the message sent by the message sending module, and the operations are completed in the same process, so that the time delay is very small.
In addition, in this embodiment, when an external frequency request is not received, the frequency of the message sending module may be counted in real time according to the manner of this embodiment, and when the frequency is externally required, the frequency is directly obtained and returned. The frequency obtained by counting does not need to take the preset time length forward according to the time of receiving the frequency request to count the frequency of the message sending module so as to ensure that the counted frequency is not influenced by the frequency request time delay, and the counted frequency is very accurate and can accurately reflect the condition of the message sending module for sending the message.
In the frequency statistical method of the embodiment, a frequency statistical device arranged in a process records a plurality of receiving moments of a plurality of messages in the process of receiving the plurality of messages which are subscribed in advance and sent by a message sending module in the same process; according to a plurality of receiving moments within a preset time length, the frequency of the message sending module for sending the message is counted, the technical problem of inaccurate frequency counting in the prior art can be solved, and because the frequency counting of the embodiment occurs in the same process, cross-process communication time delay does not exist, and the accuracy of the frequency counting of the message sending module for sending the message can be effectively improved.
Fig. 2 is a flowchart of another embodiment of a statistical method for message frequency according to the present application. As shown in fig. 2, the statistical method of message frequency in this embodiment is based on the embodiment shown in fig. 1, and takes the example that a plurality of message sending modules are included in the same process, so as to describe the technical solution of the present invention in detail. As shown in fig. 2, the statistical method for message frequency in this embodiment may specifically include the following steps:
s201, according to the current process identification, subscribing the message sent by the message sending module belonging to the same process from the message management module;
for example, the information stored in the message management module of this embodiment may include the following contents in table 1:
TABLE 1
For example, in the subscription, the statistical device of the message frequency may determine the identifier of the message sending module to be subscribed according to the identifier of the process in which the statistical device is located, in combination with table 1; and then sending a subscription request carrying the identifier of the message sending module to be subscribed to the message management module, and establishing a subscription relationship between the statistical device of the message frequency and the message sending module to be subscribed by the message management module, wherein the subscription relationship is identified by the subscription relationship between the identifier of the statistical device of the message frequency and the identifier of the message sending module. Moreover, the message management module needs to notify the message sending module of the subscription relationship, so that the message sending module can send the message to the subscribed statistical device of the message frequency at the same time when sending the message.
The difference between the frequency statistical method of this embodiment and the foregoing fig. 1 is that: in this embodiment, for example, a plurality of message sending modules are included in the same process, and the messages of each message sending module are respectively subscribed to count the frequency of each message sending module. Or in practical application, even if the same process includes multiple message sending modules, the frequency statistics apparatus may subscribe to only some messages of the message sending modules that need to focus on. In this case, the subscription may require external participation to select, for example, a worker inputs an identification of a part of the message sending modules in the co-process that needs to be subscribed to, or inputs which features of the message sending modules, and then establishes a subscription relationship with the frequency statistical device in the co-process based on the features of the message sending modules. At this time, correspondingly, information such as the characteristics of each message transmission module needs to be recorded in the message management module.
S202, in the process of receiving each message sent by each subscribed message sending module in the same process, recording the receiving time of each message sent by the message sending module in the message time cache corresponding to each message sending module;
In this embodiment, the same process includes multiple message sending modules, and a message time buffer may be configured for each message sending module, and is used to record the receiving time of the message sent by the corresponding message sending module, so as to ensure that the receiving times of the messages sent by different message sending modules are not mixed and recorded together.
S203, for each message sending module, dividing the receiving times within the preset time length by the preset time length based on the receiving time of all the messages recorded in the corresponding message time cache to obtain the message sending frequency of the corresponding message sending module;
the statistical apparatus for message frequency in this embodiment may specifically calculate the sending frequency of the message corresponding to each message sending module by creating a service in the same process, as the frequency of the message sending module, that is, the operating frequency.
And S204, for each message sending module, detecting whether the corresponding message sending module is abnormal or not according to the frequency of the message and a preset frequency threshold.
For a communication link, most modules need to perform message interaction with other modules, such as message sending and message receiving. In this embodiment, the frequency of the message sending module sending the message can also represent the operating frequency of the message sending module to a certain extent. If the working frequency is abnormal, the message sending module can be considered to be abnormal. In this embodiment, whether the corresponding message sending module is abnormal or not may be determined by monitoring the frequency of sending the message. Different frequency thresholds may be set for different messaging modules based on their operating mechanism. In this embodiment, the message frequency counting device may further detect whether the frequency of the message sent by each message sending module is lower than a corresponding preset frequency threshold, and if the frequency of the message sent by each message sending module is lower than the corresponding preset frequency threshold, the message sending module is considered to be abnormal, and if the frequency of the message sent by each message sending module is greater than or equal to the preset frequency threshold, the message sending module is considered to be normal.
In practical application, when a frequency request is sent to a frequency statistics device, the frequency statistics device sends a frequency request to the frequency statistics device, and the frequency statistics device feeds back the frequency obtained by statistics to the frequency request, so that time delay of communication among different processes in the prior art can be avoided, and accuracy of frequency is improved. For example, the technical solution included at this time may specifically include the following steps:
(a) receiving a message frequency request sent by a frequency request end;
(b) the frequency of the message sending module sending the message is sent to the frequency request terminal, and the frequency of the message sent by the message sending module indicates whether the message sending module is abnormal, so that the frequency request terminal can detect whether the corresponding message sending module is abnormal according to the frequency of the message and a preset frequency threshold, and the related records of the statistical device side of the message frequency are referred to in detail, which is not described herein again.
It should be noted that the frequency of sending messages by the message sending module returning to the frequency request end is the frequency of sending messages by the latest message sending module at the current time. That is, the frequency counting means always counts the frequency of the message in real time, and when a message frequency request is received, only the frequency of the message transmission module corresponding to the current time, that is, the latest frequency of the message transmission module is acquired without acquiring the historical message frequency of the message transmission module.
It should be noted that, if there is only one message sending module in the process, the frequency statistics apparatus may only count one message sending module according to the foregoing embodiment. If the process includes a plurality of message sending modules, the frequency of the message of each message sending module may be sent to the frequency request end according to the implementation manner of the foregoing embodiment. Or if the frequency request end only wants to request the frequency of the message of a certain message sending module, the identifier of the message sending module can be carried in the message frequency request. Correspondingly, the frequency statistical device obtains the frequency of the latest message corresponding to the identifier of the message sending module and returns the frequency to the frequency request end, so that the frequency request end can detect whether the message sending module is abnormal or not according to the frequency of the message and a preset frequency threshold value. Or may perform other service processing according to the frequency of the message sending module, which is not described in detail herein for example.
The statistical method of the message frequency of the embodiment can be applied to the field of automatic driving, and is used for detecting the message sending frequency of each module with a message transmission relation, such as a sensor module, an obstacle identification module, a planning module and the like, and further detecting whether the corresponding module is abnormal or not based on the frequency.
By adopting the above technical solution and the statistical device of the message frequency set in the process, the statistical method of the message frequency in this embodiment can perform statistics on the frequency of the message sent by each message sending module in the plurality of message sending modules in the same process, can overcome the problem of inaccurate frequency statistics in the prior art, can also avoid cross-process communication delay, and improve the accuracy of the frequency statistics of the message sent by the message sending module. In addition, in the embodiment, whether the message sending module is abnormal can be detected based on the statistical frequency, whether the message sending module is abnormal can be automatically and effectively detected, and meanwhile, the function and application of frequency statistics can be effectively expanded.
In addition, in this embodiment, according to the message frequency request of the frequency request segment, the frequency of the message sent by the message sending module, which is counted in advance, can be returned to the frequency request segment, and the frequency of the message sent by the message sending module does not need to be calculated after the message frequency request is received, so that the accuracy of the returned frequency can be effectively ensured.
