CN-116773726-B - Gas chromatograph device

Abstract

A gas chromatograph device is provided which can set a maintenance mode in advance and can thereafter perform maintenance of components by a simple operation with respect to a device main body. The gas chromatograph includes a communication unit, a setting processing unit, a first operation receiving unit, and a maintenance processing unit. The communication unit communicates with the outside. The setting processing unit sets one of the plurality of maintenance modes as a default maintenance mode based on an input from the outside via the communication unit. The first operation receiving unit is provided in the housing and receives a progress operation for advancing a maintenance sequence corresponding to a default maintenance mode. The maintenance processing section makes the maintenance sequence progress stepwise every time the progress operation is accepted by the first operation accepting section. The first operation receiving unit is commonly used in a case where any one of the plurality of maintenance modes is set as a default maintenance mode.

Description

Gas chromatograph device Technical Field The present invention relates to a gas chromatograph apparatus capable of setting a plurality of maintenance modes. Background For example, the gas chromatograph disclosed in patent document 1 below has a mode of automatically cooling the column for replacing the column, as an example of the maintenance mode. In a gas chromatograph apparatus, there is an apparatus capable of selecting and executing one of a plurality of maintenance modes by operating an information processing terminal connected to the gas chromatograph apparatus via a network. Prior art literature Patent literature Patent document 1 Japanese patent laid-open No. 10-48190 Disclosure of Invention Problems to be solved by the invention In maintenance of the gas chromatograph, a plurality of steps including operation of the information processing terminal, replacement of components included in the gas chromatograph, and the like are required. Specifically, the operation on the information processing terminal is an operation on a maintenance screen which is a screen displayed on the information processing terminal and which is a screen for performing a plurality of steps. In the maintenance of such a gas chromatograph apparatus, a person who performs the maintenance needs to travel between the information processing terminal and the gas chromatograph apparatus, and therefore takes a lot of effort. Therefore, it is also conceivable to directly connect a portable information processing terminal to a gas chromatograph apparatus and perform maintenance while operating a maintenance screen displayed on the information processing terminal in the vicinity of the gas chromatograph apparatus. However, the maintenance mode is rarely changed, and the operation of connecting the information processing terminal to the gas chromatograph every time maintenance is performed is complicated. The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a gas chromatograph apparatus capable of setting a maintenance mode in advance and thereafter performing maintenance of components by a simple operation with respect to an apparatus main body. Solution for solving the problem The present invention provides a gas chromatograph apparatus capable of setting a plurality of maintenance modes for a member provided in a housing, the gas chromatograph apparatus including a communication unit, a setting processing unit, a first operation receiving unit, and a maintenance processing unit. The communication unit communicates with the outside. The setting processing unit sets one of the plurality of maintenance modes as a default maintenance mode based on an input from the outside via the communication unit. The first operation receiving unit is provided in the housing and receives a progress operation for advancing a maintenance sequence corresponding to the default maintenance mode. The maintenance processing section makes the maintenance sequence progress stepwise every time the progress operation is received by the first operation receiving section. The first operation receiving unit is commonly used in a case where any one of the plurality of maintenance modes is set as the default maintenance mode. ADVANTAGEOUS EFFECTS OF INVENTION According to the present invention, the maintenance mode can be set in advance, and thereafter maintenance of the components can be performed by a simple operation with respect to the apparatus main body.
