Detailed Description
The technical solution in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Referring to fig. 1, fig. 1 is a schematic flow chart of a communication method of a cloth inspecting machine according to an embodiment of the present application. The communication method of the cloth inspecting machine comprises the following specific steps:
step S12: a service request message is received through a message center, the service request message including a source service, one or more target services, and service content for each of the target services.
Generally, an intelligent cloth inspecting machine system is built by a micro-service architecture, mainly comprises a control service, an algorithm service, an acquisition service, a picture storage service, a hardware control service and the like, and performs unified message management through a message center. The message center can serve software and processes, and can be message queues such as Kafka, RabbitMQ and RocktetMQ, so that the communication coordination and the communication efficiency of the cloth inspecting machine are improved.
The source service and the target service can be software processes for completing a certain specific function in the intelligent cloth inspecting machine, and the service content can be control, calculation, image acquisition, image storage, hardware control and the like.
It should be understood that the service request information received by the message center includes various types of files, such as source service, target service, service content, and the like, and therefore before the service content of each target service is sent to the corresponding file address through the message center, the source service, one or more target services, and the service content of each target service in the service request message need to be parsed by the message center based on a preset format, so as to determine the file address corresponding to each target service.
Step S14: and sending the service content of each target service to a file address corresponding to each target service through the message center.
Optionally, before performing inter-service communication through the message center, the source service and the target service need to complete registration in the message center and obtain a unique file address, and each target service receives a message by monitoring the file address.
Optionally, the Inter-service Communication in this embodiment may be performed in a UNIX Domain Socket, which is also called an IPC (Inter-Process Communication) Socket, and is used to implement Inter-Process Communication on the same host. Socket was originally designed for network communication, but later an IPC mechanism was developed on the Socket framework, namely UNIX Domain Socket. Although network sockets can also be used for interprocess communication (via a loopback address) on the same host, UNIX Domain sockets are more efficient for IPC: the data of the application layer is only copied from one process to another process without passing through a network protocol stack, packaging and unpacking, calculating a checksum, maintaining a sequence number, responding and the like. The UNIX Domain Socket is full-duplex, the API (Application programming interface) is rich in semantics, and has obvious advantages compared with other IPC mechanisms, and the IPC mechanism becomes the most widely used IPC mechanism at present, for example, communication between an X Window server and a GUI program is through the UNIX Domain Socket.
It should be understood that, after each service content of the source service is transmitted to the target service through the message center, the service result returned by each target service needs to be received through the message center, where the service result sent by each target service is a service result corresponding to the service content acquired by each target service, and specifically, the service result includes a return success message and a return failure message.
Step S16: and when the message center receives the return success messages of all the target services in the one or more target services, sending the return service success information to the source service through the message center.
Optionally, the messages transmitted between the services all carry message identifiers, for example, the service content in the source request service sent by the source service a all carries the unique message identifier of the source request service, and the message identifier may be any character combination such as numbers, letters, and the like. The specific steps of the step S16 for determining the return success message may be as follows: the message center inquires the returned return success message through the message identifier; and when the return success messages corresponding to all the target services in the one or more target services exist, determining that the return success messages of all the target services in the one or more target services are received.
Through the judging steps, the intelligent cloth inspecting machine communication method can determine whether all service contents in the service requested by a certain source service are completely executed or not through the message identification, so that the communication consistency of the intelligent cloth inspecting machine is improved.
The target service received by the message center may be a control service, an algorithm service, an acquisition service, a picture storage service and/or a hardware control service, and when the target service is a hardware service, related hardware of the intelligent cloth inspection machine needs to be controlled and communicated, please refer to fig. 2, where fig. 2 is a schematic flow diagram of hardware control service communication provided in the embodiment of the present application, where the hardware target service communicates with a programmable logic controller connected to the cloth inspection machine through a serial port, the hardware target service transmits a level signal to the programmable logic controller through an Modbus protocol through an RS232 or other serial ports after obtaining the signal by monitoring a Unix Domain Socket file, and the programmable logic controller converts the level signal into a digital quantity signal, a pulse signal, and the like to control related functions of the cloth inspection machine. The specific steps of the hardware control service communication may be as follows:
step S22: and when the target service is the hardware control service, modifying the service content of the hardware control service into a hardware service type through the message center, and sending the hardware service type to a file address corresponding to the hardware control service.
Alternatively, the hardware service type in this implementation may be a "prepare" type.
Step S24: and acquiring corresponding hardware control service content at a file address through a hardware target service based on a UNIX Domain Socket, and sending a hardware detection signal to a programmable logic controller of a cloth inspecting machine corresponding to the hardware control service content through the hardware target service by adopting a serial port.
Referring to fig. 3, fig. 3 is a schematic diagram illustrating a software and hardware communication flow of a hardware control service according to an embodiment of the present disclosure. And after the programmable logic controller of the intelligent cloth inspecting machine sends the hardware detection signal to the corresponding hardware equipment of the intelligent cloth inspecting machine, the communication detection of the hardware equipment is completed, and a level signal which represents the normal communication of the hardware equipment is returned to the hardware target service when the communication of the hardware equipment is normal, so that the hardware target service sends the service result to the message center.
The hardware equipment of the intelligent cloth inspecting machine can generally comprise a transmission module, a camera module and the like.
It should be understood that, when a target service such as a hardware target service sends a message to a message center, the message may also be sent to a monitored file address of the message center, and the message feedback of the target service is completed based on UNIX Domain Socket.
Step S26: and sending confirmation information to the target hardware service when the message center receives the return success messages of all the one or more target services and the target hardware service exists in the one or more target services.
Alternatively, the confirmation information in this embodiment may be "confirm" information.
Step S28: and after the message center receives the confirmation return information corresponding to the confirmation information sent by the target hardware service, sending the return service success information to the source service through the message center.
Optionally, in this embodiment, after the message center receives the acknowledgment return information corresponding to the acknowledgment information sent by the target hardware service, a message log may also be recorded.
In a general microservice software system, a retry and rollback mode is generally used for processing final consistency of transactions. However, in the cloth inspecting machine system, once an abnormal condition occurs, the cloth inspecting machine which has started cannot automatically roll back the rolled cloth in the hardware control service. Therefore, the message center must ensure that the hardware service does not roll back after being started, and the hardware service is submitted in two stages through the steps S22-S28, and after the success of other software services is ensured, the completion of the start of the hardware service is confirmed.
Further, when the message center does not receive the return success messages of all the target services in the one or more target services within the preset time, the message center sends the service content of the target service which does not send the return success messages to the file address corresponding to the target service which does not send the return success messages, or sends the return service failure messages to the source service.
Optionally, the message center may poll for return information for the target service.
In addition, the manager can also obtain the message log of the message center through the management background and analyze the log to monitor the running health condition of the system service.
