Abstract

PURPOSE:To easily construct a system by a method wherein respective parameters for action from a plurality of mechanism parts connected to a data processor and information which is required for their setting screens are stored in a processor and parameter setting screens are generated. CONSTITUTION:First, whether data exists inside a parameter table in a data processor or not is confirmed. When the data does not exist, a parameter set is requested and received from all peripheral devices and it is registered inside the table. Then, a form is received from each peripheral device, it is compared with constitution information inside the table. When they coincide, a parameter- setting screen for action, a data gathering operation and the like are started. When the received form does not exist inside the table, the parameter set is taken into from the peripheral device and registered newly. Then, parameter- setting-screen information corresponding to each form is taken out from the table, and the parameter-setting screen for action is generated. Thereby, a system can be constructed easily and its operability can be enhanced.

However, there are many types of peripheral devices for chromatographic analysis systems, even if they are of the same model, due to differences in performance. Therefore, the data processing device needs to have parameters corresponding to many types of analyzers and information for constructing the corresponding operation parameter input screen in the data processing device. It required a lot of memory to store.

Further, a peripheral device of a format not supported by the data processing device, that is, a peripheral device of a type in which operation parameters and information for constructing a screen for inputting them are not stored in the data processing device is controlled. I couldn't.

An object of the present invention is to store a large storage capacity by a function of taking in information from a peripheral device for constructing a parameter setting screen according to an operation parameter or format of each connected peripheral device and storing the information. Without needing
It is an object of the present invention to provide a data processing device for a chromatographic analysis system that enables system construction regardless of the type of peripheral device.

[0006]

The above object can be realized by adding the following functions to a data processing device and various peripheral devices.

(1) Data processing device 1) Information (hereinafter referred to as parameter set) relating to operation parameters sent from each connected analysis device, its unit, and a screen for inputting parameters is stored in the data processing device. Function to store in a table (hereinafter, parameter table).

2) When measuring or setting operating parameters,
Recognizing the format of each analyzer connected to the data processor, if the system configuration stored in the parameter table in the data processor differs from the actual system configuration, the analyst must enter the parameters for that analyzer. Function that prompts

(2) Each peripheral device A function of transmitting a parameter set in the peripheral device to the data processing device in response to a parameter set request from the data processing device.

[0010]

According to the present invention, the data processing device and each peripheral device are connected by communication, and the data processing device can set parameters and perform measurement by turning on the power of the data processing device and each peripheral device or by a predetermined operation of the analyst. When you need the correct system configuration, etc., the system configuration will be checked automatically.
If the system configuration information in the data processing device and the actual system configuration do not match, the system configuration information in the data processing device is made to match the actual system configuration, and the operation parameter input screen itself is newly constructed. , The analyst does not need to be aware of the limitation of the system configuration, and the system can be easily constructed.

FIG. 2 is a block diagram of a data processing device for a chromatographic analysis system and peripheral devices connected thereto.

The data processing device 1 is connected to each peripheral device 7 by a communication line 12. The data processing device
It is composed of a parameter table storage unit 2 for storing a parameter table, a display unit 4, an operation unit 5, an external communication interface unit 6, and an operation control unit 3 for controlling these and various calculations.

The peripheral device comprises a parameter set storage unit 8 for storing its own parameter set, an external communication interface unit 10, an arithmetic control unit 9 for controlling these, and an analysis unit 11.

FIG. 3 shows an example of the parameter set. In the parameter set, the model code that represents each model, the device type, the total number of parameters included in the parameter set, the name, unit, value (upper and lower limit values) of each parameter, and the data processing device It contains the information required to import the set and construct the operation parameter input screen.

FIG. 4 shows an example of the parameter table. Basically, it is a combination of parameter sets.
FIG. 4 is a parameter table in the data processing device when two pumps and two detectors are connected. However, the number of devices constituting the system is limited by the storage capacity of the parameter table storage unit in the data processing device. It is due to the limitation of.

Next, referring to FIG. 1, a system configuration automatic updating process performed before starting data collection or setting operation parameters will be described.

(Step 100) It is confirmed whether or not there is data in the parameter table storage section in the data processing device.

If there is no data, step 111
To all peripheral devices that are connected for communication,
Request transmission of parameter set.

(Step 101) In order to compare the system configuration stored in the parameter table in the data processing device with the actual system configuration, each peripheral device connected in communication is requested to transmit in the format.

(Step 102) When the peripheral device communicatively connected to the data processing device receives the signal transmitted in step 101, it transmits its own format, and the data processing device receives it.

(Step 103) The device format transmitted from each peripheral device is compared with the system configuration information stored in the parameter table.

When the number and types of the transmitted device types completely match the system configuration information in the parameter table, the target operation is started such as the operation parameter setting screen and data collection. (Step 104) If there is a device type stored in the parameter table that does not exist among the persons received from each peripheral device, the parameter set having the device type is deleted from the parameter table.

(Step 105) If any of the transmitted device types does not exist in the parameter table, one of the peripheral devices having that device type is requested to transmit the parameter set.

(Step 106) The parameter set is received and newly registered in the parameter table.

(Step 107) It is judged whether or not there is another parameter set to be registered, and if there is, a step 1
05 and 106 are repeated. If there is not, processing from step 108 onward is performed.

If yes, the operation parameter setting screen is directly displayed.
