Abstract

A calibration method of a detection device and a method for acquiring a calibration file of the detection device are described herein. The acquisition method includes generating the calibration file in an address space accessible by the detection device in a use environment according to a calibration result, and correspondingly storing a unique identification code, the calibration result, and the calibration file of each detection device. When the detection device detects an article, the method includes attempting to acquire the calibration file from itself. If the calibration file can be acquired, the method includes directly loading the calibration file. If the calibration file cannot be acquired, the method includes acquiring the calibration file from the address space accessible by the detection device in the use environment. The solution is applied to the calibration of the detection device on a production line and the use of the detection device.

First claim

The invention claimed is:

1. A method for acquiring a calibration file of a detection device, comprising:
S 1 ′: receiving and storing a calibration result of each detection device on a production line and a unique identification code thereof, generating a calibration file of the corresponding detection device according to the calibration result, and storing the calibration file,
establishing a blank table, wherein the table contains three pieces of information: the unique identification code, the calibration result and the calibration file,
filling the calibration result and the unique identification code thereof of each detection device on the production line in the established table correspondingly, and
generating the calibration file of the corresponding detection device according to the calibration result, and filing the calibration file in the table correspondingly; and

S 2 ′: receiving a calibration file acquisition request sent by the detection device and carrying the unique identification code thereof, searching for the calibration file of the detection device according to the unique identification code, and returning the searched calibration file to the detection device.

2. A method for acquiring a calibration file of a detection device, comprising:
S 1 ″: attempting to acquire a calibration file thereof from the detection device before detecting the article, if the calibration file cannot be acquired, entering step S 2 ″; if the calibration file can be acquired, entering step S 4 ″;
S 2 ″: sending a calibration file acquisition request carrying a unique identification code of the detection device to an address space accessible by the detection device in a use environment;
S 3 ″: receiving the calibration file returned by the address space for the calibration file acquisition request, and entering step S 4 ″, and
storing the calibration file; and

S 4 ″: loading the calibration file,
wherein:
in the step S 1 ″, the acquiring the calibration file thereof from the detection device comprises: acquiring the calibration file thereof from a fixed storage path of the detection device; and
in the step S 3 ″, storing the calibration file comprises: storing the calibration file on the fixed storage path in the detection device.

3. A method for acquiring a calibration file of a detection device, comprising:
S 1 ″: attempting to acquire a calibration file thereof from the detection device before detecting the article, if the calibration file cannot be acquired, entering step S 2 ″; if the calibration file can be acquired, entering step S 4 ″;
S 2 ″: sending a calibration file acquisition request carrying a unique identification code of the detection device to an address space accessible by the detection device in a use environment;
S 3 ″: receiving the calibration file returned by the address space for the calibration file acquisition request, and entering step S 4 ″; and
S 4 ″: loading the calibration file.

4. The acquisition method according to claim 3 , wherein the step S 3 ″ comprises:
monitoring in real time whether the calibration file returned by the address space for the calibration file acquisition request within a set time length is received; if so, storing the calibration file, and entering step S 4 ″; and if not, returning to step S 2 ″.

5. A storage medium, wherein the storage medium stores instruction codes, and the instruction codes are used for executing the acquisition method according to claim 3 .
