2. Description of the Related Art In a system monitoring board which is equipped with various sensors and monitors a system, monitoring is performed based on a predetermined parameter indicating a system monitoring condition. For example, the system is monitored on the basis of parameters such as the number of sensors, a data threshold value when an alarm is issued, and timed management information. This parameter is stored as variable data in the internal memory of the system monitoring board body, the variable data is read when the monitoring is performed, and the monitoring is performed under the monitoring condition based on the variable data.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a diagram showing the overall configuration of a monitoring system in this embodiment. In this embodiment, the super-sensitive smoke monitoring panel will be described.
It is not limited to this. As shown in FIG. 1, the present monitoring system includes a monitoring panel body 1, a liquid crystal display 2, other output devices 3, an input device 4, and a sensor group 5 for detecting smoke. The liquid crystal display 2 displays monitoring results, analysis results, setting screens, etc.
Further, as the other output device 3, a speaker for sounding an alarm or the like when an abnormality occurs in the system, a printer for printing the monitoring result and the like are provided. Further, the input device 4 is provided with switches, keyboards, etc. for performing various settings and operations.

In the monitoring panel body 1, a CPU 6, an LCD controller 7 for controlling display of the liquid crystal display 2, an output IF 8 for controlling output to an output device 3 other than the liquid crystal display 2, and an input to the input device 4. An input IF 9 for controlling the switch, a switch 10 for selecting analog data from the smoke sensor, and an A / A for converting the analog data selected via the switch 10 into digital data.
A D converter 11, a ROM 12 that stores a monitoring / control program and monitoring conditions generally used in a high-sensitivity smoke monitoring system, and a RAM 13 as an internal memory that stores temporary data and variable data used in the program. And a memory card 14 as an external memory for preliminarily storing variable data.

In the RAM 13 (and the memory card 14), the number of sensors 5, the data threshold value at the time of issuing an alarm,
Variable data as monitoring conditions such as time management information is stored in a predetermined format, and checksum data is also stored for each predetermined data. The memory card 14 is detachably attached to the surveillance board body 1, and can be attached to and detached from a slot provided in the surveillance board body 1. Also, memory card 1
By removing 4 from the monitoring panel body 1 and inserting it into the slot of another computer (not shown), the data of the memory card 14 can be read and stored on that computer.

Further, the ROM 12 stores in advance the monitoring conditions generally used in the high-sensitivity smoke monitoring system as data (hereinafter referred to as initial data). Here, a program stored in the CPU 6 and the ROM 12 determines a normality of the memory, a normality determining unit, a reading unit that reads data stored in the memory, a writing unit that writes data in the memory, and a monitoring condition indicating a monitoring condition. The monitoring condition setting unit for setting the priority switch and the priority switch determination unit for determining whether or not the priority switch (not shown) is pressed are realized. The normality determination unit determines whether the RAM 13 is normal or not.
The AM normality determination unit, the memory card normality determination unit that determines the normality of the memory card 14, and the ROM normality determination unit that determines the normality of the ROM 12 are included. The reading unit reads data from the RAM 13. RAM reading section,
It is composed of a memory card reading unit that reads data from the memory card 14 and a ROM reading unit that reads data from the ROM 12. Further, the writing unit writes the data of the RAM 13 to the memory card 14, the RAM data writing unit that writes the data of the memory card 14 to the RAM 13, and the data of the ROM 12 to R.
It is composed of an AM 13 and a ROM data writing section for writing in the memory card 14. Details of these will be described later.

Next, a method of setting the monitoring condition in this embodiment will be described. FIG. 2 shows a flowchart for setting the monitoring conditions according to this embodiment. When the power of the monitoring panel body 1 is turned on, first, the priority switch determining section determines whether or not a priority switch (not shown) provided on the monitoring panel body 1 is pressed (step S1). When the priority switch determination unit determines that the priority switch is pressed, the priority switch processing described later is performed. On the other hand, if it is determined that the priority switch has not been pressed, the following initial setting processing of monitoring conditions (steps S2 to S13) is performed. In the initial setting process of the monitoring condition, when the variable data stored in the RAM 13 is normal, the variable data in the RAM 13 is set as the monitoring condition indicating the monitoring condition, and when the variable data in the RAM 13 is not normal, the memory card is set. The variable data stored in 14 is set as the monitoring condition. If the variable data of the memory card 14 is not normal, R
The initial data stored in the OM 12 is set as a monitoring condition.

The initial setting process of the monitoring condition will be described more specifically. First, the RAM normality determination unit determines whether the variable data stored in the RAM 13 is normal (step S2). Here, the RAM normality determination unit (and the memory card normality determination unit) calculates the consistency between the checksum data and the variable data stored in the RAM 13 described above, and the variable data becomes normal (in the correct format). Judge whether it is stored. If the checksum data and the variable data do not match, or (for example, R
If the data cannot be read (because the AM 13 is broken, etc.), it is determined to be not normal, and if the checksum data and the variable data are consistent, it is determined to be normal.

When it is determined that the variable data in the RAM 13 is normal by the calculation of the consistency in the RAM normality determination unit, the RAM reading unit reads the variable data stored in the RAM 13 (step S).
3). Then, the read variable data of the RAM 13 is
The data is written in the memory card 14 by the RAM data writing unit (step S4). By copying the variable data stored in the RAM 13 to the memory card 14 as described above, the variable data copied to the memory card 14 can be copied even when the variable data in the RAM 13 is not normal as described later. By using, it is possible to set the monitoring conditions without stopping the operation of the system monitoring panel. Then, the variable data of the RAM 13 read by the monitoring condition setting unit is set as the monitoring condition of the monitoring system (step S5), and the smoke monitoring process is performed based on this monitoring condition (step S6).

On the other hand, if it is determined in step S2 that the variable data stored in the RAM 13 is not normal, the variable data stored in the memory card 14, which is a preliminary external memory, is used to determine the monitoring condition. Settings are made. That is, when the variable data stored in the RAM 13 is not correct data (not stored in the correct format) or the RAM 13 cannot be read, the variable data stored in the RAM 13 is used to set the monitoring condition. Since this is not possible, the preliminary variable data stored in the memory card 14 is used to set the monitoring conditions. Also in this case, the memory card normality determination unit first determines whether or not the variable data stored in the memory card 14 is normal (step S7). This judgment of normality is the same as the processing in the RAM normality judgment unit described above. Note that the memory card 14 is removable from the monitoring panel body 1, but if the memory card 14 is not attached to the slot of the monitoring panel body 1, the memory card normality determination unit determines that it is not normal. .

By the memory normality judging section, the memory card 1
When it is determined that the variable data of No. 4 is normal, the variable data stored in the memory card 14 is read by the memory card reading unit (step S8). Then, the read variable data of the memory card 14 is written in the RAM 13 by the memory card data writing unit (step S9). Even when the variable data in the RAM 13 is not normal as described above, by copying the variable data in the normal memory card 14 to the RAM 13, RA
The abnormality of the variable data of M13 can be repaired. As a result, when the variable data in the RAM 13 is referred to next time, the RAM normality determination section determines that the RAM is normal. Then, the variable data of the memory card 14 read by the monitoring condition setting unit is set as the monitoring condition of the monitoring system (step S10), and the smoke monitoring process is performed based on the monitoring condition (step S).
6). In this way, the variable data is preliminary stored in the memory card 1
If the data is stored in memory 4, the monitoring condition can be set using the variable data of the memory card 14 even when the RAM 13 is broken, so that the operation of the system monitoring panel is stopped and the variable data is set. No need to fix.

On the other hand, if it is determined in step S7 that the variable data stored in the memory card 14 is not normal, the monitoring data is set by using the initial data stored in the ROM 12, which is a supplementary memory. Is done. That is, the variable data stored in the memory card 14 is used because the variable data stored in the memory card 14 is not correct data or the memory card 14 is not inserted into the slot of the monitoring panel body 1. If you cannot set the monitoring conditions, ROM
The monitoring condition is set using the initial data stored in 12. Since the ROM 12 is a read-only memory, the stored data is not normally changed. Therefore, since the initial data stored in the ROM 12 is always the same, the normality judgment made on the RAM 13 and the memory card 14 is not performed.

First, the ROM reading unit reads the initial data stored in the ROM 12 (step S1).
1). The read initial data of the ROM 12 is the ROM
RAM 13 and memory card 14 by the data writing unit
(Step S12). As a result, RA
Even if the data of both M13 and memory card 14 is not normal, RAM13 and memory card 14
The contents of can be initialized by the initial data stored in the ROM 12. Needless to say, the above writing is not performed when the memory card 14 is not inserted into the slot of the monitoring panel body 1.

Next, the monitoring condition setting unit sets the read initial data of the ROM 12 as the monitoring condition of the monitoring system (step S13), and the smoke monitoring process is performed based on this monitoring condition (step S6). If the initial data is auxiliary stored in the ROM 12 as described above, even if both the RAM 13 and the memory card 14 are damaged, the initial data in the ROM 12 can be used to set the monitoring condition. There is no need to stop operation of the monitoring panel and reset variable data.

Next, the priority switch process will be described.
FIG. 3 shows a flowchart of the priority switch process according to FIG. This priority switch processing is performed when the priority switch determination unit determines that the priority switch is pressed, as described above. If the priority switch is not pressed, the above-mentioned initial setting process of the monitoring condition, that is, the reference of the RAM 13 which is the internal memory is first tried, and then the reference of the memory card 14 which is the external memory is tried, and finally the auxiliary. Initialization processing of the monitoring condition is performed in which the monitoring condition is set by trying to refer to the ROM 12 which is a memory. On the other hand, if the priority switch is pressed when the power is turned on, the priority switch process (steps S20 to S31) in which the order of the above references is changed as shown in FIG. 3 is performed. That is, the memory card 14 is first tried, then the RAM 13 is tried, and finally the ROM 12 is tried to set the monitoring condition. Hereinafter, the priority switch process will be specifically described, but a part not particularly described is similar to the monitoring condition initial setting process.

First, the memory card normality determination unit determines whether the variable data stored in the memory card 14 is normal (step S20). If it is determined to be normal, the same processing as steps S8 to S10 in the initial setting of the above-described monitoring conditions, that is, reading the variable data of the memory card 14 (step S21), the read variable data to the RAM 13 is performed. Writing (step S2
2), monitoring conditions are set (step S23).
Then, a smoke monitoring process is performed based on this monitoring condition (step S24).

Further, when the memory card normality judging unit judges that the variable data stored in the memory card 14 is not normal, the RAM normality judging unit makes a RAM.
It is determined whether the variable data stored in 13 is normal (step S25). When the RAM normality determination unit determines that the variable data in the RAM 13 is normal, the same processing as steps S3 to S5 in the initial setting of the monitoring conditions, that is, the variable data in the RAM 13 is read (step S26) and read. The variable data is written into the memory card 14 (step S27), and the monitoring condition is set (step S28). Then, a smoke monitoring process is performed based on this monitoring condition (step S2).
4).

Further, the RAM normality judgment unit uses the RAM.
If it is determined that the variable data stored in 13 is not normal, step S1 in the initial setting of the monitoring condition is performed.
1 to S13, that is, the reading of the initial data of the ROM 12 (step S29), the writing of the read initial data to the RAM 13 and the memory card 14 (step S30), and the setting of the monitoring condition (step S31). Done. Then, a smoke monitoring process is performed based on this monitoring condition (step S24).

By providing such a priority switch process, it is possible to change the variable data of the RAM 13 while minimizing the suspension of the operation of the system monitoring board.
That is, the memory card 14, which is an external memory, can be removed from the monitoring panel body 1, and the data in the memory card 14 can be read and stored by another computer.
Further, since variable data in the RAM 13 or the ROM 12 can be referred to as described above, it is possible to operate the system monitoring board even if the memory card 14 is not attached to the monitoring board body 1. Therefore, first, the memory card 14 is removed from the monitoring panel body 1, and new variable data is stored in the memory card 14 by another computer. After that, if the memory card 14 is inserted into the slot of the monitoring panel body 1 and the priority switch is pressed at the next power-on, the new variable data is set as the monitoring condition (step S23), and the RAM 13 is also newly changed. The data is copied (step S22). RAM1 like this
When changing the variable data of No. 3, it is possible to minimize the suspension of the operation of the system monitoring board.

By the way, in this embodiment, the monitoring conditions are updated at regular intervals not only when the power is turned on but also when the system monitoring board is in operation. FIG. 4 shows a flowchart of this monitoring condition update processing. The process of updating the monitoring conditions is basically the same as the initial setting of the monitoring conditions described above. That is, the RAM normality determination unit is the RAM 1
It is determined whether or not the variable data stored in 3 is normal (step S40), and when it is determined that the RAM 13 data is normal, the variable data in the RAM 13 is read (step S41). Is updated as a monitoring condition (step S42). Here, in the initial setting process of the monitoring condition, the variable data is transferred to the memory card 1.
4 (step S4), the monitoring condition update processing does not write the read monitoring condition to the memory card 14. This is because the RAM normality determination unit normally determines that the operation is normal, and thus writing the data to the memory card 14 each time the monitoring condition is updated is not efficient.

If it is determined in step S40 that the variable data stored in the RAM 13 is not normal, the memory card normality determining unit determines that the memory card 1
It is determined whether the variable data stored in No. 4 is normal (step S43). If it is determined to be normal, step S in the initial setting of the above-mentioned monitoring conditions.
The same processing as 8 to S10 is performed, that is, the variable data of the memory card 14 is read (step S44), the read variable data is written to the RAM 13 (step S45), and the monitoring condition is set (step S46).

Further, when it is determined in step S43 that the variable data of the memory card 14 is not normal, steps S11 to S1 in the initial setting of the monitoring condition are performed.
The same process as in step 3, that is, reading of the initial data from the ROM 12 (step S47), RA of the read initial data
Writing to M13 and memory card 14 (step S4
8) The monitoring condition is set (step S49).
In this way, the monitoring conditions are updated even during operation of the system monitoring panel, and when the RAM or the like is abnormal, the variable data (or initial data) stored in the memory card 14 (or the ROM 12) is used to update the RAM or the like. Since the data can be recovered, the reliability of the surveillance system is greatly improved.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-mentioned embodiment and may be implemented in various different forms within the scope of the technical idea thereof. Hereinafter, these different forms will be described. Although the memory card 14 is used as the external memory in the present embodiment, the present invention is not limited to this, and any other external storage medium may be used. For example, a floppy disk, a magneto-optical disk or the like can be used. Also, for internal memory and auxiliary memory, RAM,
It is not limited to ROM. Further, in the present embodiment, the priority switch process is performed by pressing the priority switch, but the present invention is not limited to this, and the priority switch process (priority input process) may be performed by another input.
For example, priority input processing may be performed when a signal is input from the outside of the monitoring panel body.

In the above-mentioned monitoring condition updating process, when the RAM normality determining unit determines that the variable data in the RAM is normal, the variable data in the RAM is not written in the memory card. Alternatively, the variable data in the RAM may be written in the memory card. For example, the variable data in the RAM 13 is changed by a conventional method (by pressing a switch of the monitor panel body 1 or by operating another computer serially connected to the monitor panel body).
It is also possible to check whether the change has been made and write the contents of the RAM to the memory card when the change has been made by the conventional method.

As described above, the present invention has the internal memory storing predetermined variable data, and sets the system monitoring conditions based on the variable data stored in the internal memory. Setting method, the external memory that stores the variable data in advance is provided, the normality of the internal memory is judged, and if the internal memory is judged to be normal, the variable of the internal memory is changed. If the monitoring conditions are set based on the data and the internal memory is not normal, the external memory is normal and the external memory is normal. Since the monitoring conditions are set based on the variable data in the external memory, the variable data stored in the external memory is stored even if the variable data in the internal memory is not normal. By using, there is an effect that it is possible to set the monitoring conditions without stopping the operation of the system monitoring panel.

According to a second aspect of the present invention, an external memory for preliminarily storing variable data and an auxiliary memory for storing predetermined initial data are provided, and the normality of the internal memory is judged. If the internal memory is judged to be normal, the monitoring conditions are set based on the variable data in the internal memory, while if it is judged that the internal memory is not normal, the normality of the external memory is set. If it is determined that the external memory is normal, the monitoring condition is set based on the variable data of the external memory, and if it is determined that the external memory is not normal, the auxiliary memory is initialized. Since the monitoring condition is set based on the data, use the initial data stored in the auxiliary memory even when the variable data in both the internal memory and the external memory is not normal. Therefore, there is an effect that it is possible to set the monitoring conditions without stopping the operation of the system monitoring panel.

Further, according to the present invention as defined in claim 3, since the external memory is detachably provided to the main body of the system monitor board, the external memory is removed from the main body of the monitor board.
Since it can be attached to another computer or the like, there is an effect that the data in the external memory can be easily read and stored using the computer or the like. Further, there is an effect that it can be easily stored / stored in various other recording media through a computer or the like.

According to the present invention of claim 4, it is judged whether or not a predetermined input is made, and if the predetermined input is made, the normality of the external memory is judged and the external memory is normal. If it is determined that the monitoring condition is set based on the variable data of the external memory, on the other hand, if it is determined that the external memory is not normal, the normality of the internal memory is determined and When it is determined that the memory is normal, the monitoring conditions are set based on the variable data in the internal memory, and when it is determined that the internal memory is not normal, the monitoring is performed based on the initial data in the auxiliary memory. Since the condition is set, there is an effect that the variable data stored in the external memory can be set as the monitoring condition with priority over the variable data stored in the internal memory. In particular, when variable data as a new monitoring condition is stored in the external memory using a computer external to the main body of the monitoring panel, the suspension of operation of the system monitoring panel is minimized, and the variable data based on the external memory is used. You can change to new monitoring conditions.

Further, according to the present invention as set forth in claim 5, since the variable data is written to the external memory after reading the variable data from the internal memory, the normal contents of the internal memory are copied to the external memory. Even if the internal memory is destroyed, it is possible to appropriately set the monitoring condition by using the contents of the external memory.

According to the sixth aspect of the present invention, since the variable data is written to the internal memory after reading the variable data from the external memory, the normal external memory can be used even if the internal memory is broken. Since the contents of is copied to the internal memory, there is an effect that the contents of the internal memory can be restored to a normal state.

Further, according to the present invention of claim 7, after the initial data is read from the auxiliary memory, the initial data is written to the internal memory and the external memory.
Even if the contents of both the internal memory and the external memory are abnormal, the contents of the auxiliary memory are copied to the internal memory and the external memory, so the contents of these internal memory and the external memory are initialized to the normal state. The effect is that you can.

Further, according to the present invention, since the monitoring conditions are set at predetermined intervals, the normality of the internal memory, the external memory, etc. is always judged during the operation of the system monitoring board. When there is an abnormality, the contents of the internal memory or the external memory are restored appropriately, so that the reliability of the monitoring system is significantly improved.
