Description

[Detailed explanation of the invention] This invention displays images such as figures and time on the CRT display screen according to the input of external signals, and when a predetermined specific external signal such as fire or crime prevention is input, The present invention relates to an operation recording device for disaster prevention equipment that records in hard copy a CRT screen displaying images corresponding to signals and time.

Generally, schools, buildings, etc. are equipped with automatic fire alarm equipment that detects fire and issues an alarm, and disaster prevention equipment that detects intruders and issues an alarm.In recent years, these facilities have been centrally monitored. For centralized monitoring in rooms, etc., centralized monitoring systems using computers are used to process various information.

By the way, a computer-based centralized monitoring system for disaster prevention equipment is equipped with a CRT display device, printer, etc. as ancillary equipment to facilitate monitoring operations.
Although it is not displayed or printed, for example, if a security guard performs key operations on a keyboard to view the floor plan of all the first floors of a building,
A plan view of all floors on the first floor is displayed on the CRT display screen, and at the same time, the printer records the fact that the display process has been performed. On the other hand, when a specific external signal such as a fire or crime prevention signal is input, the CRT display will display the floor indicating that a fire has occurred or there is an intruder, and at the same time the printer will display the information on which floor the fire or theft occurred at what time. Launch,
This launch is shown in red etc. to distinguish it from normal processing records.

However, when looking at the characters recorded by a printer at a later date to investigate the occurrence of a fire or theft, conventional recording methods record data as simplified data using symbols or encoded characters. The records were very difficult to read, and there was a risk that it would not be possible to fully understand the contents of the records.

The present invention was developed by focusing on these conventional problems, and it displays the time on the CRT display at all times, and when a predetermined specific external signal such as fire or crime prevention signal is input, the specific external signal is displayed. Based on the determination result, the image corresponding to the specific external signal displayed on the CRT display device is output to the hard copy device and recorded along with the display time, making it easier to understand records of fires, thefts, etc. It is an object of the present invention to provide an operation recording device for disaster prevention equipment that allows the recorded contents to be easily and fully understood.

Hereinafter, the present invention will be explained based on the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

First, to explain the configuration, 1 is a control circuit section using a computer, and a central processing unit (hereinafter referred to as
(referred to as a CPU) 2 and a recording device 3 using a drum disk, flexible disk, etc., and the recording device 3 has a control program for central monitoring control, and a program for displaying images in response to key input or external signal input. File information that records images, output control programs that output control signals for operating alarm bells, etc. in response to input of specific external signals such as fire or crime prevention are stored.
Furthermore, a specific signal discrimination program for discriminating that the external signal is a predetermined specific external signal such as fire or theft is stored. An external signal from a fire receiver or a security receiver is inputted to the signal line of the CPU 2 via an input interface 4, and a clock circuit 5 is connected to output a time code for displaying the time. . on the other hand,
As a display means, CRT is connected to the signal line of CPU2.
A controller 6 is connected, and the CRT controller 6 has a video RAM 7 that temporarily stores image data transferred in response to display control commands from the CPU 2. The CRT controller stores images in the video RAM 7 written under the control of the CPU 2. Information on CRT
It has a configuration to be displayed on a display 8. Furthermore,
A hard copy device 10 is provided as a recording means.
It has a function of reading image data from the video RAM 7 connected to the controller 6 and recording it on recording paper. Although not shown, an operation console equipped with a keyboard or the like for inputting key inputs is also connected to the signal line of the CPU 2.

Next, the operation will be explained with reference to the operation flow shown in FIG.

First, in the steady monitoring state, as shown in decision block 11, the CPU 2 of the control circuit section 1 scans to see if there is a signal input by key operation on the input interface 4 or the operation console. The time code from clock circuit 5 is
CRT controller 6 under time control of CPU 2
is written to a specific address in the video RAM 7 in minutes, and is read out under the read control of the CRT controller 6.
The hours and minutes are displayed in the corners of the CRT display 8 screen. Next, if a key input is made on the keyboard of the operation console to cause the CPU 2 to display, for example, a plan view of the first floor of a building, the CPU 2 responds to the key input according to the control program in the storage device 3. The image information is read out and transferred to the video RAM 7 of the CRT controller 6, and the CRT controller 6 transfers it to the video RAM 7 as shown in block 12 of FIG.
The image information transferred to is read out and the plan view of the first floor is displayed as an image on the CRT display 8. When such a signal is input, the CPU 2 determines whether or not it is a specific signal as shown in decision block 13. In this case, since it is not a predetermined specific signal such as for fire and crime prevention, processing is continued. finish.

Next, suppose that a fire detector installed on a specific first floor of the building detects a fire, and a fire detection signal is input from the fire receiver to the CPU of the control circuit unit 1 via the input interface 4. In response to the interrupt caused by the signal input, the CPU 2 reads out the plan view of the entire first floor stored in the storage device 3 in response to the fire signal, as shown in block 12 in FIG. RAM
7, and the CRT controller 6 is the video RAM
The image information stored in 7 is displayed on a CRT display 8, for example, as shown in FIG.

The floor plan of the first floor, which is the area where the fire occurred, displayed on the CRT display 8 is the warning area.
F ₁ - It is divided into 1 to 5, for example, a restricted area.
If a fire breaks out in _F1-4 , the section where the fire occurred is distinguished from other sections and displayed in color or blinking. In addition, the display F ₁ indicating that the display floor is the first floor is shown in the left corner of the display screen,
Furthermore, the time is displayed in the lower right corner of the display screen based on the time code from the clock circuit 5. When the image is displayed on the CRT display 8 in this way, the process proceeds to the determination block 13 in FIG. 2, where it is determined whether or not it is a specific signal.Since the fire signal is a predetermined specific signal, the CPU 2
The hard copy controller 9 instructs the hard copy controller 9 to perform recording control, and the hard copy controller 9 that receives this recording control command controls the video of the CRT controller 6.
Image data of a display image as shown in FIG. 3 written in the RAM 7 is recorded by a hard copy 10. Therefore, the record in the hard copy 10 includes a floor plan showing the floor where the fire occurred, an indication showing where the fire occurred in the section in the plan, and a record of the time when the fire occurred based on the clock circuit 5. By looking at the hard copy record results, it is possible to easily and accurately grasp the area and time of fire occurrence on the floor where the fire occurred, and furthermore, in the event that the fire spreads to other sections. Since the hard copy device 10 records the fire detection for each compartment, the spread of the fire can be recorded sequentially, and by examining the recorded results later, the location of the fire and the spread of the fire can be determined. Able to accurately grasp the situation, etc.

Furthermore, by using hard copies, it is possible to accurately grasp information such as in what area and at what time the fire broke out, in what direction the fire is spreading, and at what time and minute, so prompt evacuation guidance can be given. , or it becomes possible to carry out fire extinguishing activities.

The above-mentioned action was taken as an example of fire detection, but the same applies to the input of a theft detection signal from disaster prevention equipment, where a figure such as a plan view indicating the place where the theft occurred and the time of occurrence are displayed in hard copy. can be recorded by
