Method for converting SECSGEM communication protocol

Abstract

The invention discloses an SECSGEM communication protocol conversion method. The communication protocol conversion method comprises an uplink method and a downlink method. The method comprises the following steps: S1, capturing data displayed on a device screen by using a screen character recognition program deployed on a remote server; S2, the captured display data is sent to an SDR through SOCEKT, and after the SDR receives the data sent by the OCR, service classification is identified through data content; S3, the SDR converts the received data into standard Stream Function according to anSECS / GEM communication protocol internally and sends the standard Stream Function to the EAP host; and the EAP host converts the data into a standard Stream Function for logic processing. According tothe invention, an automatic communication standard protocol with high flexibility and high efficiency is provided, and a communication protocol layer and a controller environment are compatible.

Description

technical field [0001] The invention relates to the technical field of communication protocol conversion, in particular to a SECSGEM communication protocol conversion method. Background technique [0002] In the semiconductor manufacturing industry, the current equipment automation networking communication protocols at home and abroad are based on the connectivity standard SECSGEM protocol formulated by the International Semiconductor Equipment and Materials Association (SEMI), but there is no equipment integrating the SECSGEM protocol for electronic circuits, PCB and other industries. There is no general standard at home and abroad, and foreign countries are promoting OPC UA as a communication protocol standard for PCB equipment; currently, TPCA in Taiwan, China has proposed a relevant PCBECI communication protocol, which is also based on SEMI (semiconductor communication protocol). [0003] SECS / GEM is a connectivity standard protocol developed by Semiconductor Equipment a...

Problems solved by technology

[0005] 1. The communication protocols of non-standard equipment are messy: such as TCP / IP, HTTP, OPC-UA, Web Server, MQTT, etc. There are many communication methods for equipment. Due to the continuous iterative innovation of technology, it is difficult to unify the communication protocol layer. Compatibility and mutual conversion of multiple protocols will cause a lot of development and operation and maintenance costs for equipment manufacturers and factory-side systems;

[0006] 2. The development cycle of SECSGEM is long and the implementation cost is high: SECSGEM driver development requires professional engineers who are familiar with SECSGEM communication logic, and at the same time, it needs to be on the device side;

[0007] 3. The control system environment of non-standard equipment is messy: there are various situations in the control system environment of non-standard equipment, and SECSGEM only supports Windows environment
