A method for anti-error processing of two-way asynchronous input

Abstract

The invention discloses a two-way asynchronous input error prevention processing method, which is executed by a controller and used to match the input of materials with the input of their identity information, wherein at least two A sensor, the material is attached with identification information representing its identity information, and the controller is electrically connected to the sensor and an input device for inputting the identification information of the material, so as to receive the shading detection signal of the sensor And the identification information input by the input device. The double-path asynchronous input error prevention processing method provided by the present invention ensures the accuracy of the corresponding relationship between the materials in the material frame and the input identification information.

Description

technical field [0001] The invention relates to the field of information processing, in particular to an error prevention processing method for two-way asynchronous input. Background technique [0002] In life or production scenarios, there are many cases where there is an asynchronous two-way input between the physical input of the material and the input of its identity information. For example, scan an object to obtain its identity information, then place it in an initial position, and then The executive agency performs corresponding operations on it according to its identity information. The ideal situation is to scan a code, put an object, and correspond one by one in order, but this method is extremely error-prone. For example, accidentally scanning an object If you have scanned the QR code twice, or if you are interrupted by external affairs during the manual operation, and you are not sure whether the material in your hand has been scanned when you return to the proce...

Problems solved by technology

[0002] In life or production scenarios, there are many cases where there is an asynchronous dual input between the physical input of the material and the input of its identity information. For example, scanning an object to obtain its identity information, and then placing it in an initial position, and then by The executive agency performs corresponding operations on it according to its identity information. Ideally, it is to scan a code, put an object, and correspond one by one in order, but this method is extremely error-prone, for example, accidentally scanning an object If you have scanned the QR code twice, or if you are interrupted by external affairs during the manual operation, and you are not sure whether the material in your hand has been scanned when you return to the process, then for the sake of safety, you will scan the code again and cause a material to be scanned twice. Or, if you take a material and scan the code, and find that it is a defective product, you will replace the material and scan the code. The above situations will make the material identification information obtained by scanning the code and the material unable to achieve continuous one-to-one correspondence.

Especially without knowing it, all the one-to-one correspondences are wrongly matched, which seriously affects the production results

[0003] In addition, when the machine fails and restarts, the material and the corresponding identity information are easily misplaced and matched. If it cannot be found in time, it will cause a series of subsequent problems. Therefore, how to reduce or even avoid the current cutting pieces and the corresponding information in the system The mismatch of related information is particularly important
