Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an FA system, etc.
The present invention relates to a monitoring system that enables efficient analysis of causes of equipment troubles and the like later.

[0002]

2. Description of the Related Art This type of monitoring system records a phenomenon photographed by a camera on a VTR of, for example, an endless tape, and is used in such a manner that the VTR is reproduced later to investigate the cause of trouble. is there. However, in this case, some phenomena cannot be endured because the phenomena recorded on the tape must be viewed in order from the beginning.
A similar monitoring system may also be used in biotechnology research, and may be used to analyze the rapid growth phenomenon of bacteria. Even in such a case, even if it is desired to see only the rapid proliferation phenomenon as described above, it is very troublesome because the tape must be rewound to see all the phenomena recorded on the tape. Further, in a crime prevention system, for example, when a person who operates a caching machine abnormally is photographed by using a similar surveillance system and it is to be verified later, it is necessary to see all the phenomena recorded on the tape from the beginning. It must be inefficient.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems such as the complexity of the above-mentioned conventional monitoring system, and has an automatic editing function for extracting and recording only what the monitor wants to see. The challenge is to provide a surveillance system.

[0004]

As means for technically solving the above-mentioned problems, the present invention provides a camera means for monitoring a phenomenon and a first recording means for recording a phenomenon photographed by this camera means. When an abnormality occurs in the phenomenon, an abnormality detecting means for detecting the abnormality and generating a Q signal, a second recording means for recording the phenomenon before and after the Q signal, and a Q signal generated by the abnormality detecting means The monitoring system includes at least a control unit that receives a signal and records a phenomenon recorded in the second recording unit at a required time before and after the Q signal recorded in the first recording unit. It is a thing. Further, a third recording means for recording the phenomenon photographed by the camera means while the phenomenon before and after the Q signal recorded in the first recording means is recorded in the second recording means is included. Use as a summary.

[0005]

[Operation] According to the monitoring system configured as described above, only the phenomenon desired by the observer is recorded in the second recording means. Therefore, the observer reproduces the second recording means to analyze, verify, etc. Can be performed efficiently.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the accompanying drawings. In FIG. 1, reference numeral 1 is a camera means for photographing a monitored body 2 such as a dicer, transmitting the phenomenon to the control unit 3, and recording it in the first recording means 4.
The first recording means 4 is a magnetic tape recording means (VTR).
That is, the phenomenon transmitted from the control unit 3 is constantly recorded.

The abnormal phenomenon of the monitored object 2 is detected by an abnormality detecting means (not shown). If the monitored object 2 itself has an abnormality detecting means, replace it with the abnormality detecting means. Can be done. For example, an alignment unit for detecting the streets of the wafer is attached to the dicer, and if the alignment is not good, an abnormal signal may be issued and the abnormal signal may be transmitted to the control unit 3 as a Q signal.

Control unit 3 which receives the Q signal
Causes the first recording means 4 to continue the recording for a required time (for example, 10 seconds) to capture the phenomenon after the Q signal. After that, the required amount of magnetic tape of the first recording means 4 is rewound,
The phenomenon before and after the Q signal (for example, 20 seconds before and 10 seconds after) is made ready to be transmitted to the second recording means.

Next, the control unit 3 is connected to the second
The recording means 5 of (1) and the first recording means 4 are operated to transmit the phenomena before and after the Q signal to the second recording means 5 for recording.

While the phenomenon before and after the Q signal is being transferred from the first recording means 4 to the second recording means 5, the phenomenon photographed by the camera means 1 is not recorded in the first recording means 4. . Therefore, the control unit 3 transmits the phenomenon photographed by the camera means 1 to the third recording means 6 and records it in order to prevent the recording failure during this period.

The third recording means is the first recording means 4
Similarly, the phenomenon of photographing by the camera means 1 is recorded at any time, and the first recording means is backed up. Therefore, when the third recording means 6 records the phenomenon before and after the Q signal, the control unit 3 transmits and records the phenomenon before and after the Q signal from the third recording means 6 to the second recording means 5. It During this time, the first recording means 4 backs up the third recording means 6.

By repeating the above operation, only the phenomenon before and after the Q signal is recorded in the second recording means 5 in the state where there is no recording leakage. In this case, if the date, hour, minute, etc. of the Q signal are recorded in the second recording means 5 at the same time, they can be effectively utilized at the time of later analysis.

When the monitored object 2 itself has an abnormality detecting function, it is not necessary to separately provide an abnormality detecting means as described above. However, for example, in the case of catching an abnormal phenomenon such as bacteria in biotechnology research. An abnormality detection means is required.

The abnormality detecting means include the following. When the monitored object emits heat, it emits a Q signal in response to the heat. When the monitored object emits sound, it emits a Q signal in response to the sound. When the monitored object emits light, it emits a Q signal in response to the light. When the monitored object emits a gas such as CO ₂ , it emits a Q signal in response to the gas. When the shape of the monitored object changes, image processing is performed using a CCD camera or the like, and a Q signal is emitted based on the amount of change. These can be appropriately selected depending on the type of monitored object. In short, the observer can arbitrarily decide what he wants to see.

The abnormality detecting means is not limited to one, but a plurality of abnormality detecting means may be used, and the phenomenon of the monitored object can be recorded in the second recording means 5 from various angles. In this case, if the type of the Q signal is recorded at the same time, it can be effectively used in the later analysis. The first to third recording means are not particularly limited, and a magnetic tape, a magnetic disk, an optical disk or the like can be appropriately used. Also, the first to third recording means may be three independent recording means, but may be one recording means. For example, one magnetic disk may be divided into three areas to configure the first to third recording means. Furthermore, when random access is possible, it is possible to mix the first to third recording means without dividing the area.

[0016]

As described above, according to the present invention,
It is possible to provide a monitoring system with an automatic editing function that extracts and records only what the observer wants to see, and from this the phenomenon recorded in the VTR at the time of analysis of the cause of trouble of the monitored object can be provided from the beginning. Since it is not necessary to look at all in order, it is efficient and eliminates the complexity of the past, and it is easy to observe the rapid growth phenomenon of bacteria etc. in bio-research and elucidate criminal cases. In this case, it has an excellent effect such as quick verification.
