BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a superimpose control system used in a system that uses a controller to control the quality of products or monitor the status of development equipment in the field of instrumentation control.

0003

[Prior art] Steel using a control controller,
In fields such as glass, when an abnormality occurs from the controller, an alarm is generated for the control system,
It only alerts the operator. After confirming the alarm, the operator performs a corresponding process for the alarm. However, even if the system is such that the controller issues an alarm to the control system when it detects an abnormality, it cannot be assumed that the controller is always operating normally.
Also, if the settings for the controller are incorrect, abnormalities will occur many times. It becomes a very difficult task for the operator to think about how to respond each time.

0004

[Problems to be Solved by the Invention] The conventional system described above has the following problems. Firstly,
The controller detects an abnormality and issues an alarm to the operator, but the operator cannot visually see the state in which the alarm has occurred. Second, what should the operator do after confirming the alarm?
It is difficult to judge just by the occurrence of an alarm. Third, even if the operator responds to the alarm, it is difficult to judge whether the system is operating normally. Fourth, it is difficult to determine whether the controller is abnormal or normal.

[0005] The present invention has been made to eliminate such conventional drawbacks, and when the controller notifies an abnormality, the operator visually observes the condition on the screen and takes action to deal with the abnormality. The purpose of the present invention is to provide a superimpose control system that can perform the following tasks.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a superimpose control system comprising a camera such as a CCD, a control controller, a superimpose device, a storage device, and a control system. ,
The control controller and the camera are integrated and controlled, and when the controller confirms an abnormality, the control system has a function of generating an alarm, and the data monitored by the camera at the time of alarm generation is stored in the storage device. a function to impose the state at the time of alarm occurrence on the monitor screen of the control system from the superimpose device, a function to retain data after corresponding processing, and a function to redisplay the monitor data at the time of alarm occurrence. It is characterized by having the function of performing

[0008]

[Operation] In the present invention, when an abnormality is confirmed, the controller sends an alarm signal to the control system and generates an alarm to the operator. Further, data monitoring the state at the time of alarm generation is held in the storage device, and is superimposed on the monitor screen of the control system by the superimposing device. When an alarm occurs, the operator visually observes the state at the time of occurrence on the monitor screen and takes appropriate action. The monitor data after corresponding processing is held in the storage device according to the signal from the control system. Further, in response to a request from the control system, the monitor data at the time of alarm occurrence is retrieved from the storage device and redisplayed.

Embodiments Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a block diagram of a superimpose control system according to an embodiment of the present invention. This superimpose control system includes a CCD 1, a controller 2, a superimpose device 3, a storage device 4, and a control system 5.
The controller 2 and CCD 1 are integrally controlled. The control controller 2 is controlled by a control signal 19 from the control system 5. When an abnormality is confirmed,
The controller 2 sends an alarm signal to the control system 5 to generate an alarm to the operator. Also,
When an abnormality is confirmed, the data from monitoring the condition is
stored in the storage device 4 and superimposed device 3
is imposed on the monitor screen provided in the control system 5. When an alarm occurs, the operator visually observes the state at the time of occurrence on the monitor screen and takes appropriate action. Next, the operation of this system will be explained. The superimposing device 3 normally receives video data 11 from the CCD 1.
The memory is cleared at regular intervals without being retained. When an abnormality is confirmed in the controller 2, the data retention signal 12 is transmitted from the controller 2, and the data stored in the memory in the superimpose device 3 is retained in the storage device 4, and the control system 5 is prepared. The imposed screen data 14 is inserted into the screen of the monitor being displayed. The controller 2 sends a data holding signal 12 to the superimposing device 3 and at the same time generates an alarm signal 13 to the control system 5. This alarm notifies the operator of the control system 5 of the occurrence of an abnormality.

[0010] The superimposing device 3 displays the screen when it receives the data holding signal 12 for a certain period of time. By visually checking this screen, the operator can understand the state when the alarm occurs and can take appropriate countermeasures. Thereafter, the monitor screen of the control system 5 continues to display the current status after the corresponding processing. This display continues until the operator clears the screen. When the superimposing device 3 further receives the data holding signal 17 from the control system 5, the superimposing device 3 stores the data after corresponding processing in the storage device 4. When data is stored in the storage device 4 from the superimpose device 3, the data is held together with the month, date, and time from the clock LSI in the superimpose device 3. Upon receiving the impose clear signal 18 from the control system 5, normal operation is resumed.

When a redisplay signal 15 for displaying monitor data at the time of alarm occurrence is input from the control system 5 to the superimposing device 3, the superimposing device 3
reads the stored data 16 from the storage device 4, copies it to its own memory, and imposes the screen data 1 on the control system 5.
Send 4. Thereby, the monitor data at the time of the alarm occurrence or the data after the corresponding processing can be redisplayed and checked again. Note that it is also possible to have the storage device 4 hold the state after the corresponding processing.

0012

As described above, according to the superimpose control system of the present invention, it is possible to visually check the monitor data when an alarm occurs, so that appropriate countermeasures can be taken. In addition, since the data at the time of alarm occurrence and the data after response processing are retained in the storage device, the state at the time of alarm occurrence and the state after response processing can be checked at a later date, and the system can be used for quality control and development equipment. This is effective when monitoring the status of.
