Description

[Detailed description of the invention]

The present invention relates to a general control device for testing equipment, and in particular aims to improve human-machine communication, prevent erroneous settings and erroneous operations, facilitate operation, and enable safe and efficient experiments. As the scale of test equipment increases, central control devices are being adopted to centrally monitor and control each device to make experiments safer, more efficient, and save labor. However, the conventional
The main functions of the overall control of the test equipment were to set and change experimental conditions on the control panel of each equipment, and to centralize the starting, stopping, monitoring, and recording of equipment all at once. An example of a large-scale device that has been under development in recent years is a nuclear fusion experimental device. This type of equipment is comparable in size to a general plant, and the cost for a single experiment is enormous, so it is essential to improve the safety and efficiency of experiments while saving labor in operation. In addition, one of the special characteristics of fusion experiments is that the experimental conditions vary widely, the conditions are changed for each experiment, a large number of facilities are operated in short cycles (for example, 10 minutes), and large amounts of data are handled at high speeds. The issue of human-machine communication, including the centralization of condition settings, is important. Adopting a central control device is effective as a countermeasure against these problems, but the conventional functions are insufficient, placing a significant burden on operators, risking operational errors, and making it difficult to conduct experiments safely and efficiently. Have difficulty. The purpose of the present invention is to eliminate the drawbacks of the above-mentioned techniques, and to provide a general control device equipped with man-machine communication that is free from erroneous settings and operations, is easy to operate, and enables safe and efficient experiments. It is in. The present invention is characterized by concentrating the experimental condition setting section for the entire equipment in a central control device, having an experimental condition setting control section that has a function of determining the rationality of set values, and furthermore, an experimental control unit that controls the operation of the equipment during experiments. The test section is equipped with a pre-experiment check section that determines the readiness status of the equipment, and the results of the test are displayed to the operator via a man-machine interface. Experimental examples of the present invention will be explained in detail below.

The value set by the experimental condition setting device 11 is input to the experimental condition setting control section 21, which displays the value on the display 12, and also performs rationality judgment and displays the result on the display 12. If the judgment result is that it is defective, it is reset, and if it is good, it issues a setting instruction to the block control device 3 and passes the setting value to the pre-experiment check section 22. Each block control device 31 to 3N performs setting control of experimental conditions in the block equipment and pre-experiment preparation operations.
This is executed by each block device 41 to 4N. 31-3

The operator judges the situation from the contents displayed on the display 15 and operates the experiment start switch 13 to perform the experiment by controlling the block equipment 3 and 4 in an integrated manner. The status information of each block equipment is constantly displayed on the monitor 15, and the protective operation in case of an abnormality is entered into the experiment control section 23, and the experiment is stopped when necessary. FIG. 2 shows the flow of the aforementioned procedure. The determination section marked 〓 in the figure is the main part of the present invention, and is the rationality determination of the experimental condition setting values and the equipment preparation state determination section. The flowchart for the second and subsequent experiments when repeating the experiment without changing the experimental conditions is shown below. That is, the pre-experiment check function is kept active during the experiment and monitors and controls the preparation status of the equipment for each experiment. As an example of application, a system diagram of a toroidal magnetic field coil power supply is shown in FIG. 3, and the current, voltage, and voltage pattern of the system are shown in FIG. This is a facility that supplies high-power DC power as a plasma stabilization power source for a large-scale nuclear fusion experimental device, and shows a case where power is received from the grid and a motor generator MG with a flywheel, taking into account load fluctuations and equipment economics.
