As shown in fig. 1. The communication system of the production equipment and the upper system based on socket communication comprises an upper system module and a lower equipment module, wherein the lower equipment module can detect the running state and parameters of the equipment and collect data, the upper system module is in communication connection with the lower equipment module, the upper system module can process and respond to the data received from the lower equipment module, and the upper system module can also actively send a control instruction to the lower equipment module.
The process flow shown in fig. 2 will be described in detail below with reference to the specific embodiments, and the contents may be as follows:
In implementation, when a communication requirement exists between the lower device and the upper system, the lower device module can integrate and package data to be transmitted to form a data packet. Specifically, the communication requirement is determined based on the lower device application in the lower device module, the lower device application may include several aspects such as device status detection and device operation control, and when a scene requiring communication with the upper system is triggered in the execution process of the lower device application, the data acquisition step before communication is actively performed. In addition, the lower device module can respond to the signal of the upper system and passively acquire data and feed the data back to the upper system.
Therefore, the lower equipment module can obtain the data packet to be transmitted, and the data transmission between the lower equipment module and the upper system is convenient.
In a specific embodiment, since the upper system and the lower device are separately designed, if the communication is interrupted, the data processing and transmission are not valid, and accordingly, step 201 may further include the following processing: the lower equipment module sends a communication test signal to the upper system module, and the upper system module responds and returns a signal of successful communication based on the communication test signal after receiving the communication test signal.
In implementation, the step of the communication test may be initiated by the upper system module or initiated by the lower device module, and referring to fig. 3, taking the case that the lower device initiates the communication test, if the initiator does not receive a signal that the communication is successful within a preset time interval, the sender may determine that the communication between the upper system and the lower device is failed; if the online reply of the upper system module is received, the subsequent processing can be carried out.
Therefore, a group of sub-modules for realizing communication signal testing are arranged in the lower equipment and the upper system, so that the testing of the communication condition between the lower equipment and the upper system is facilitated through the communication testing sub-modules, the auxiliary communication system is facilitated to master the communication environment, the step of processing the application data under the condition of communication failure is facilitated to be avoided, and the waste of computing power in the system is avoided.

Therefore, before the data packet is sent, the lower device module may translate the data packet so that the data or the instruction in the data packet conforms to the predetermined communication protocol model, and then encapsulate the translated data packet to obtain an encapsulated data packet. After the lower equipment module acquires the encapsulated data packet, the encapsulated data packet is sent to the upper system module, and the encapsulated data packet at the moment follows a preset communication protocol model, so that the data in the encapsulated data packet can be normally used after the upper system module receives the data.
Specifically, the preset communication protocol model may be defined and preset by a user, and since the communication relationship between the upper system module and the lower device module is bidirectional in the application, the communication protocol model is simultaneously applied to the upper system module and the lower device module. The data communication between the lower device and the upper system can be named, the active and passive directions initiated by the data communication process can be defined, and the data communication can be classified. According to the basic functions, the data communication functions can be divided into 7 categories, such as equipment connection and state (BME 0 XX), master control (BME 1 XX), processing lot correlation (BME 2 XX), job control (BME 3 XX), equipment data (BME 5 XX), process recipe (BME 6 XX), master control notification (BME 9 XX), and the like, so as to realize the complete functions of the automation equipment:
device on-line and status (BME 0 XX): a communication test request transmitted in both directions between the lower device and the upper system; the lower device sends a communication establishing request, a connection request, an off-line request, a device state change report and the like to the upper system;
master (BME 1 XX): a time synchronization request and the like sent by the lower device to the upper system; a master control command and the like sent by an upper system to a lower device;
batch correlation (BME 2 XX): the lower device sends a device login and logout, a material check, an ID matching, a carrier login and logout, a device information request and the like to the upper system;
job control (BME 3 XX): the lower device sends an operator authority check to the upper system;
device data (BME 5 XX): the lower device sends a device abnormal event report, a device alarm event report, a QC check result report, a device parameter report and the like to the upper system; a device parameter request sent by the upper system to the lower device;
process recipe (BME 6 XX): job inquiry and the like sent by the upper system to the lower equipment; an ID request and a file downloading request sent by the lower device to the upper system;
master notification (BME 9 XX): and the upper system issues abnormal information, warning information, notification information and the like to the lower equipment.
In addition, a start symbol, an end symbol, a field separator, a field list separator, etc. of the data communication may be defined.
In this way, the data sent by the lower device can be translated based on the communication specification shared between the lower device and the upper system, so that the data can be successfully transmitted and applied.
And 203, after the upper system module receives the encapsulated data packet, analyzing the encapsulated data packet based on the same communication protocol model to obtain an analyzed data packet.
In implementation, after the upper system module receives the encapsulated data packet sent by the lower device module, the encapsulated data packet may be analyzed based on the same preset communication protocol model to obtain an analyzed data packet, and the analyzed data packet also includes available data and instructions.
In one embodiment, the automated production equipment has a high requirement on safety, and an illegal operation may cause economic and even human injury loss, so correspondingly, the communication method between the production equipment based on socket communication and the upper system may further include the following processing: the upper system module acquires the identity information of the user, retrieves and contrasts the identity information with a preset user database, and acquires a verification result.
In implementation, when identity information matched with the user exists in the user database, the authentication can be regarded as successful, otherwise, the authentication can be regarded as failure. The upper system module can feed back the condition of the verification failure and refuse to receive the input information of the current user. When the verification is successful, the upper system module can assign the designated operation authority to the user according to the identity information of the user.
Like this, help verifying the operator's of upper system identity, and then reduce the possibility of unusual personnel of identity control subordinate's equipment, help improving the security of system, simultaneously, different use identities can correspond different operation authorities, distinguish and distribute the operation authority, help improving the flexibility on the upper system uses the authorization, help fully improving communication system's availability factor.
And 204, after the upper system module acquires the analysis data packet, executing corresponding processing or response based on the analysis data packet.
In implementation, after the upper system module obtains the parsing data packet, the upper system module may execute corresponding processing or respond based on available data and instructions in the parsing data packet.
