Problems solved by technology
[0003] During the process of implementing the present invention, the inventor found that there are at least the following problems in the prior art: since the warehouse equipment control system is a multi-threaded system, multiple instructions may appear simultaneously In the case of sending, in this case, the message sent by the warehouse equipment control system will contain multiple instructions, and there may be incomplete instructions
In this case, the existing message processing method cannot completely obtain all the instructions in the message, and there is a problem of instruction loss

The invention discloses a message processing method and device, and relates to the technical field of computers. One specific embodiment of the method comprises the following steps of: repeatedly executing the following interception steps on a message until no character exists in the message: determining whether an instruction character string, an instruction front-section character string or an instruction rear-section character string exists in the message or not; when the instruction character string exists, intercepting the instruction character string; when the instruction front-section character string exists, storing the instruction front-section character string; when the instruction rear-section character string exists, splicing the instruction rear-section character string to theinstruction front-section character string, and intercepting the formed instruction character string; and if the conditions are not met, searching the instruction head identifier, deleting the characters in front of the instruction head identifier, and if the instruction head identifier is not found, deleting all the characters. According to the embodiment, all instructions in the message can becompletely acquired.
Description
technical field [0001] The present invention relates to the field of computer technology, in particular to a message processing method and device. Background technique [0002] At present, in the intelligent warehouse, the shuttle car is usually equipped with a PLC control system. The PLC control system of the shuttle car obtains instructions from the warehouse equipment control system through the communication of TCP / IP messages with the warehouse equipment control system. [0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: since the warehouse equipment control system is a multi-threaded system, multiple instructions may be sent at the same time. In this case, the warehouse equipment control system sent The message will contain multiple instructions, and there may be incomplete instructions. In this case, the existing packet processing method cannot completely obtain all the instruc...
