Electronic price tag log display method and device and computer storage medium

Abstract

The invention discloses an electronic price tag log display method and device and a computer storage medium. The method comprises the steps of detecting and receiving a trigger display instruction of an operation log corresponding to an electronic price tag through a Hall switch based on the electronic price tag, and triggering a main chip of the electronic price tag to generate interruption; based on the main chip of the electronic price tag, calling the operation log stored in a pre-allocated cache space by the electronic price tag; and outputting the operation log to a display screen corresponding to the electronic price tag and displaying the operation log, so that a user analyzes possible problems of the electronic price tag based on the displayed operation log. The purpose of displaying the operation log of the electronic price tag on the screen of the electronic price tag is achieved, so that the electronic price tag is debugged more conveniently; and furthermore, under the condition that the normal operation of the electronic price tag is not influenced, the operation log recorded by the electronic price tag is sent to a base station to be stored, so that the durability and the safety of the data are improved.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to an electronic price tag log display method, device and computer storage medium. Background technique [0002] At present, for the operation log of the electronic price tag, that is, the log of the electronic price tag, there are two main obstacles to its storage and acquisition: one is, because the electronic price tag is a single-chip computer system, subject to factors such as cost, the memory of the electronic price tag It is very small, generally only about 2K, which determines that too many running logs cannot be stored in the memory; the other is that the electronic price tag communicates with the base station through the 2.4G air interface protocol, and the communication parties have strict timing requirements, so There is not enough time to allow the electronic price tag to output the running log Log to the flash area with sufficient storage space; because the...

[0002] At present, for the operation log of the electronic price tag, that is, the log of the electronic price tag, there are two main obstacles to its storage and acquisition: one is, because the electronic price tag is a single-chip computer system, subject to factors such as cost, the memory of the electronic price tag It is very small, generally only about 2K, which determines that too many running logs cannot be stored in the memory; the other is that the electronic price tag communicates with the base station through the 2.4G air interface protocol, and the communication parties have strict timing requirements, so There is not enough time to allow the electronic price tag to output the running log Log to the flash area with sufficient storage space; because the flash is used as a peripheral of the electronic price tag, although the space is sufficient, the data input and output interface, that is, the I / O interface reads and writes consumption. , will affect the timing of the communication

Based on the above two points, it is very difficult to debug the electronic price tag at present.
