Fig. 1 is a flowchart of a method for constructing an embedded software system based on a multi-process architecture idea, as shown in fig. 1, the method for constructing an embedded software system based on a multi-process architecture idea includes:
step 101: acquiring an actual service scene, and constructing one or more service logic processes according to the actual service scene; each business logic process comprises a plurality of functions; the multiple functions comprise a parameter receiving and starting function, a parameter analyzing and starting function, an interactive information channel establishing function, an interactive information sending function and an interactive information analyzing function; the business logic processes are independent from each other.
The business logic process refers to an application program (for example, reading keyboard input) for completing one or more specific works, different workers need to be built in different business scenes, and the business logic process can have a visual user interface or no user interface.
The Worker has the following capabilities after being constructed:
the capability to receive and analyze the startup parameters delivered by the Agent.
Has the capability of establishing an Msg tunnel with an Agent.
Has the capability of sending Msg to an Agent.
Has the ability to receive the Msg from the Agent and analyze this Msg.
Msg is a short string (utf-8 encoded) and individual messages are preferably controlled to within 2048 bytes, conforming to the JSON specification. The basic format of each message is a JSONOBJECT type (data type in JSON specification), and the format is fixed, so that uniform analysis is facilitated, and the specific format is as follows: { "msgname": xxx, yyy: yyy } } if there is no message content, also complies with the above format requirements, for example: { "msgname": this is one of the simplest message contents that meets the JSON specification requirements.
Step 102: constructing a proxy process according to the actual service scene and compiling a proxy process configuration file; the agent process configuration file comprises a business logic process name, a starting parameter, a business logic process daemon rule and a message forwarding rule.
The agent process is responsible for the starting and guarding (program crash restart) of one or more Workers; and processing the Msg sent by the Worker to the Agent or forwarding the Msg among the workers, thereby realizing communication among different workers and management on the workers.
The agent process is developed by adopting QT technology, can realize cross-platform (window platform and linux platform), and does not need repeated coding. The embedded system automatically starts the agent process after starting (by configuring the starting parameters of the operating system or configuring the agent process as a daemon process).
The Agent configuration file comprises information such as a Worker name, a starting parameter, a Worker guard rule, a message forwarding rule and the like, and the file content conforms to the JSON specification.
For example:
procname: the name of Worker.
guard: and (5) a daemon rule, 0: not daemon, 1: daemon (the Agent is responsible for restarting the process).
cmd: and starting parameters.
auto: when 0: the agent process is started, the process is not started, and when 1: the agent process is started, the process is automatically started.
spmsg: this Worker is responsible for the list of accepted message names. Note that: there may be multiple processes for a message.
Step 103: and configuring an application program self-starting item in the operating system, so that the agent process is automatically started after the operating system is started, and restarting the operating system.
Step 104: and automatically starting the agent process, wherein the agent process starts the business logic process according to the agent process configuration file.
The step 104 further includes: starting one or more business logic processes by using the agent process, or using the agent process to defend one or more business logic processes; processing the interactive information sent to the agent process by the service logic process by using the agent process; and forwarding the interactive information among the plurality of business logic processes by utilizing the agent process.
The starting of one or more business logic processes by using the agent process or the daemon of one or more business logic processes by using the agent process specifically includes: reading the agent process configuration file by using the agent process, and constructing a service logic process structure list; the business logic process structure body list comprises a plurality of business logic process structure bodies; the business logic process structure body is internally stored with a business logic process name, a starting parameter, a business logic process daemon rule and an association table of the business logic process and an interactive information name; sequentially starting the service logic processes under the appointed path according to the service logic process structure list, transmitting the starting parameters corresponding to the service logic processes under the appointed path to the service logic processes, and constructing an interactive information channel between the agent process and the service logic processes; and under the support of the operating system, based on the interactive information channel, utilizing the agent process to monitor the running state of the business logic process in real time.
Starting and guarding about Worker:
after the Agent is started, the Agent configuration file is read, and one or more specified Worker is started according to the rule specified in the configuration file. The Worker exists as a child process of the Agent, the Agent as a parent process can sense the state of the child process (which is supported by an operating system), so that the Agent can sense the state after the Worker exits, the Worker can be restarted, and the guard function is realized.
The monitoring of the running state of the business logic process in real time by using the agent process based on the interaction information channel under the support of the operating system further comprises:
after any business logic process exits, searching a business logic process daemon rule corresponding to the exited business logic process from the business logic process structure list by using the agent process;
judging whether the exited business logic process needs to be guarded or not according to the business logic process guarding rule;
if yes, restarting the business logic process by using the agent process;
if not, the proxy process does not do any processing.
The startup and daemon process of the Worker will be explained next:
(1) the Agent reads the configuration file, a Worker structure body list is established in the memory, and the name, the starting parameter, the guard rule, the correlation table of the Worker and the Msg name and the like of the Worker are stored in the structure body.
(2) And the Agent sequentially starts the Worker under the specified path according to the Worker structure body list and transmits the relevant starting parameters to the Worker.
(3) And finishing the establishment of the Msg channel between the Agent and the Worker.
(4) Under the support of an operating system, the Agent can monitor the running state of the Worker in real time.
When a certain Worker exits, the Agent can immediately sense the Worker, at the moment, a corresponding protection rule is searched from a Worker structure list, if protection is needed, the Agent restarts the Worker, and the execution is started from the step (2); if no daemon is needed, no processing is done.
The forwarding of the interaction information among the plurality of business logic processes by using the agent process specifically includes:
after the Agent is started, the Agent configuration file is read, the Msg name which can be processed by a Worker is obtained, and an association table of the Worker and the Msg name is established; meanwhile, a SOCKET of local UDP is established, an idle port number is randomly bound, Msg sent by a Worker is monitored in real time, the port number is transmitted to the Worker in a starting parameter mode, the Worker informs the Agent of the port number of the UDP of the Worker in the Msg mode after starting, and therefore the Msg channel between the Agent and the Worker is well established.
After the Msg tunnel is successfully established, the Agent can forward the message, and the process is as follows:
worker1 sends Msg1 named xxx.
The Msg1 is sent to the Agent through the established Msg tunnel.
And searching a Worker and Msg name association table in the memory by the Agent, and finding a Worker2, a Worker3 and the like capable of processing the Msg 1.
Preprocessing is carried out on the Msg1, for example, when the Worker2 is not started, the Worker2 is started according to the starting rule of the Worker2 (refer to a Worker starting and guarding flow).
The Msg1 is forwarded to the Worker through the pre-established Msg tunnel of the Agent, the Worker2, the Worker3 and the like.
Step 105: and the agent process enters a daemon state and a message forwarding state of the business logic process to construct a multi-process software system.
After the Agent, the Worker and the Agent configuration document are constructed, deployment must be carried out according to a specified path.
Take the example of a Linux system:
# define GB _ AI _ ROOT/home/orangepi/ait runtime environment ROOT directory (for example)
GB _ AI _ ROOT/clientagent proxy process path
GB _ AI _ ROOT/worker1/worker1 worker1 path
GB _ AI _ ROOT/worker2/worker2 worker2 path
And the Agent starts a homonymous process from the operator name to the homonymous directory under the running environment root directory.
In summary, the construction method of the present invention is applied to practice, and the specific steps are as follows:
(1) and constructing one or more Works according to the actual service scene plan.
(2) And compiling an Agent configuration file according to the actual service scene.
(3) And (5) carrying out system release, namely, after the Agent, the Worker and the Agent configuration file are constructed, deploying according to a specified path. The Agent, the Worker and the Agent configuration file are deployed according to a specified path, and the path of the Agent is 'GB _ AI _ ROOT/client'; the Agent configuration file and the Agent are under the same directory; for example, the path of the business logic process named "work 1" is "GB _ AI _ ROOT/worker1/worker 1".
(4) And configuring an application program self-starting item of the operating system, so that the Agent can be automatically started after the operating system is started.
(5) The operating system is restarted.
(6) The Agent is automatically started.
(7) And the Agent starts a Worker according to the content of the Agent configuration file.
(8) The Agent enters a Worker guard state and a message forwarding state.
(9) And completing the construction of the multi-process software system.
