Embodiment Construction

[0059]In order to improve the accuracy of sampling needle calibration when calibrating the detection device, embodiments of the present application provide a calibration method, device and terminal equipment for the detection device.

[0060] refer to figure 1 Shown is a schematic diagram of a detection device. The detection device 100 includes: a metal sheet 101 , an instrument needle 102 , a processor 103 and a sample arm 104 .

[0061] Wherein, the metal sheet 101 is made of metal, and there is a hole in the middle for inserting the instrument needle 102 into the cleaning pool, which is usually installed on the edge of the cleaning pool, and can also be arranged on other movement paths of the instrument needle. The metal sheet 101 is used to simulate the liquid level. In the embodiment of this application, only a metal sheet with a ring structure is used as the target conductive medium to simulate the liquid surface. The material and shape of the metal sheet 101 can be adj...

Abstract

The invention discloses a detection device calibration method, device and terminal equipment, which belong to the technical field of detection. The method comprises steps: based on an inputted calibration instruction for position calibration on the detection device, the instrument needle of the detection device is subjected to position reset, and capacitance between the instrument needle and a target conductive medium is monitored in real time; the instrument needle is horizontally moved, when the acquired capacitance is determined to be higher than a first preset threshold, horizontal movement operation is stopped, and horizontal movement displacement is acquired; the instrument needle is subjected to vertical position reset; the instrument needle is vertically moved, when the acquired capacitance is determined to be higher than a second preset threshold, vertical movement operation is stopped, and vertical movement displacement is acquired; and based on the horizontal movement displacement and the vertical movement displacement, target calibration parameters are determined. Thus, errors by manual observation can be avoided, and the calibration accuracy is improved.

Description

technical field [0001] The present application relates to the technical field of detection, and in particular to a calibration method, device and terminal equipment of a detection device. Background technique [0002] In the prior art, when performing position calibration of instrument needles (eg, sampling needles, reagent needles) in the detection device, engineers usually need to perform manual calibration. For example, the engineer observes whether the position of the sampling needle reaches the target position, and according to the observation results, calibrates the sampling needle, and records the horizontal and vertical displacements obtained when the calibration is completed as the target calibration parameters. In this way, the detection device can move the sampling needle according to the target calibration parameters during subsequent operations such as sampling. [0003] However, through manual calibration, there will be a large position deviation, and the cali...
