ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the system controller of any of the following analyzers: a high-speed liquid chromatograph, a gas chromatograph, a liquid chromatograph/mass spectrometer or a gas chromatograph/mass spectrometer.
2. Description of the Related Art
A high-speed liquid chromatograph comprises some of the following units: a feed pump, a detector, an automatic sampler and a column oven, all of which require parameter settings. Other analyzers also comprise some units requiring parameter settings. Such analyzers prepare a number of parameters to control these units, in order to cope with various analysis conditions. The analyzers comprise a system controller, which controls these units through these parameters. The system controller displays these parameters on a display.
A conventional system controller immovably displays these parameters on the same position of the display, and displays all available parameters on a single screen.
While there are many available parameters, those changed in daily analysis are extremely limited. When changing a portion of the parameters, many unnecessary parameters displayed on the display are so obstructive it takes time to search for the target parameter. If the parameter to be changed is displayed on a lower portion of the screen, it inconveniently takes time to move the cursor on the screen to select the parameter.
SUMMARY OF THE INVENTION
Accordingly, the object of the present invention is to make system controller parameter screens easier to view and easier to operate for the user, thereby eliminating any inconveniences.
The system controller for an analyzer, according to the present invention, comprises a parameter display part for displaying parameter conditions to control each unit, a parameter condition storage part, a parameter-input part, a parameter condition transmission part and a parameter input processing part. The parameter display part has an upper-hierarchical parameter screen displaying only the selected parameter(s) and a lower-hierarchical parameter screen displaying all parameters. The parameter condition storage part stores display
on-display modes on the upper-hierarchical parameter screen and parameter conditions of each parameter as data. The parameter-input part inputs the display
on-display modes on the upper-hierarchical parameter screen and the parameter conditions of each parameter. The parameter condition transmission part transmits the parameter conditions for each parameter to a corresponding unit. The parameter input processing part transmits data from the parameter input part to the parameter condition storage part, and transmits the data stored in the parameter storage part to the parameter display part and the parameter condition transmission part.
The lower-hierarchical parameter screen displays every parameter of all available units, and the upper-hierarchical parameter screen displays only the parameter(s) selected in the lower-hierarchical parameter screen. This parameter display part may have a single upper-hierarchical parameter screen and a number of lower-hierarchical parameter screens corresponding to respective units.
The parameter display part first displays the upper-hierarchical parameter screen. The displayed parameter screen can be switched by key operation. After selecting an arbitrary parameter on any of the lower-hierarchical parameter screens, the selected parameter is displayed on the upper-hierarchical parameter screen. The user can adjust the upper-hierarchical parameter screen displaying only the parameter(s) to be used in response to any desired analysis by selecting one or a plurality of parameters in any of the lower-hierarchical parameter screens, which then enables the user to bring the parameter screen of the system controller to a usable state.
The upper-hierarchical parameter screen of the system controller according to the present invention displays only the frequently changing parameter(s), whereby the parameter screen can be rendered easier to view and easier to operate for the user, thus eliminating any inconveniences.
The foregoing along with other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.
