Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a signal processing device for disaster prevention equipment that processes signals in response to signals from monitoring terminals, etc. in disaster prevention equipment for fire, gas leakage, theft prevention, etc. Regarding.

[Prior art and its problems] A signal processing device in a conventional disaster prevention equipment will be explained using FIG. 3. In the figure, the central processing unit CPU includes a read-only memory ROMI for programs, a random access memory RAM1 for working, an operation display unit OD via an interface IFa, and a fire detection unit via an interface IFb. A monitoring terminal such as a gas leak detector or a gas leak detector is connected to an external device ED such as a controlled device or a printer via an interface IFe.

When a signal is input from the operation display unit OD or a monitoring terminal, the central processing unit CPU
After processing the input signal using the program in the only memory ROM1, it is sent to the external device ED via the interface IFc.The processing results sent via IFc are sent out continuously for each process. Must. For example, input signal A
The processing results Ar and Br for
, and Arz, and BrI and Br2, and divide them into A
It is not possible to send rl, BrI, Ar2, Br2 in the order, and if A and B are input in the order, A
r, Br order, or A r 1, Ar2, Br
, , B r2 must be sent in this order.

Therefore, if the signal input B occurs while the processing result Ar for the signal input A is being sent to the external device ED, the signal input B will be processed after sending the processing result Ar.

However, it generally takes time to send data to an external device such as a printer, and even if a new signal is input, it is not possible to process the new signal input quickly, and multiple signals If these are input simultaneously or consecutively, it may not be possible to process them.

This will be explained using the time chart of FIG. 3a. Signals A, B, C as shown in Figure 3a (1) to (4)
, D are input simultaneously or consecutively, the third a
When the signal A is first received as an input signal as shown in FIG. 3a (5), then the signal A is
The processing result Ar is sent to an external device ED, etc., but if this processing result Ar has many scenes as shown in Fig. 3a (6), the signal B is sent as shown in Fig. 3a (5). and C
is not received, and the next signal received is the signal input after completion of sending the processing result Ar. In this way signal = 4
- B and C will not be processed, and even if these signals B and C indicate, for example, that a fire shutter is open and closed, respectively, there will be no change in the state of the fire shutter at the receiving end. This will cause a serious problem in controlling disaster prevention equipment.

In an application titled "Signal processing device for disaster prevention equipment" filed by the present applicant on the same day as the present application, in order to solve the above problems, a first memory capable of storing a plurality of data created by a signal processing section is proposed. and when data is stored in the first storage means from the signal processing section, data information regarding the storage location of the data in the first storage means is stored in the order in which the data is stored in the first storage means. and a command means for outputting the earliest data information stored in the second storage means to the sending unit when the sending unit becomes ready for data sending. In this example, a signal input is taken in, processed and stored in a first storage means, and then sent out when there are no subsequent signal inputs to transmit the processing results to an external device, which takes time to send out. has been done.

The technology of this application effectively solves the problems of the prior art described above. However, in actual operation, the type of external equipment (for example, the type of external equipment, location, data There may be cases where it is desired to remove only the processing time (processing time, etc.) from control, that is, to not send the processing results to the processing time.In this invention, we have developed a disaster prevention equipment that can effectively deal with such cases. The purpose is to provide a signal processing device.

[Means for Solving the Problems] Therefore, according to the present invention, in a signal processing device for fire prevention equipment that includes a signal processing section and a sending section that sends data created by the signal processing section to an external device. , a first storage means capable of storing a plurality of data created by the signal processing section; and when data is stored in the first storage means from the signal processing section, the type of the data and the first storage means; a second storage means for storing data information including at least a storage location of the data in the means; a designation means for designating the type of data whose transmission to the external device is to be stopped; and a designation means for determining the type of data by the designation means. When specified,
It is determined whether or not the specified type is stored in the second storage means, and when data information of the specified type is stored in the second storage means, the first Discrimination erasing means for erasing the memory of the corresponding data in the storage means, and erasing the corresponding data information in the second storage means. Ru.

[Example code] An embodiment of the present invention will be described below.

FIG. 1 is a block circuit diagram partially showing the internal configuration of a control device for controlling disaster prevention equipment, and shows a central processing unit C.
The PU is shown connected to various read-only memories and random access memories as shown. Read-only memory ROM
l0 is for program storage, and random access memory RAMl0 is for work.

Random access memory RAM 20 is for storing transmission data, and is for temporarily storing the results of processing signal input.

Random access memory RAM 30 is for data storage area management, and is for storing whether or not data can be stored in RAM 20.

Random access memory RAM 40 is for storing the sending order, and is used for storing the order in which the processing results stored in RAM 20 are sent to external equipment and the type of processing results.

Various devices are also connected to the central processing unit CPU via interfaces. interface ip
, an operating unit OP is shown connected to the interface IF2, and another receiver or control device having a monitoring terminal for another area is shown connected to the interface IF2. A monitoring terminal of the control device is connected to F3 via a receiving circuit RC, and signals such as an abnormality detection signal are inputted from these monitoring terminals. There are various types of monitoring terminals, such as those for fire detection, gas leak detection, and peace prevention. Therefore, abnormality detection signals from the monitoring terminal include fire signals, gas leak signals, crime prevention signals, etc. .

Further, an external device is connected to the interface IF4, and a display circuit DP is connected to the interface IF5. External equipment includes fire doors, smoke dampers, fire shutters, etc. that operate in response to input signals.
Controlled equipment such as fire extinguishers and air conditioners, printers,
Furthermore, items such as CRT display panels are included.

To give an overview of the operation, when multiple signals are input simultaneously or continuously from a control device or a monitoring terminal, a sufficient area or area is created for each signal input to temporarily store the processing results. It is checked from the contents of RAM 30 (third storage means) whether or not the first storage means, that is, RAM 20, has enough area, and if there is enough area, the input signal is processed by the data processing section and the processing result is stored in RAM 2.
0, and the order in which they are to be sent to the external device via the sending unit, ie, the interface IP, is stored in the second storage means, ie, the RAM 40.

After there are no more signal inputs to process, R,A M2O
The processing results stored in the RAM 40 are sent to the external device in the order in which they were stored, and when the sending is finished, the free area of the RAM 20 resulting from the sending of the processing results is stored in the RAM 30, and the data is stored in the RAM 40. The transmission order for the processing result is deleted.

In this way, the time-consuming process results can be sent to an external device after the signal input has been taken in and processed, thereby reducing the problems caused by the prior art.

Furthermore, in actual operation, it may be desirable not to output created data only to external devices of the following types. In addition to the type of equipment, the types include, for example, the floor of the building, the location, and the data creator. Such a case can be handled by storing the type of processing result in the RAM 40.

In other words, when removing external devices of the following types from control,
In order to stop sending out the sending data that has already been stored in the RAM 20, when the type is inputted using a specifying means such as a numeric key on the operation panel OP, etc., the discrimination erasing means (steps 102 to 106; see FIG. 2) ) searches for something equivalent to this type from the RAM 40 and erases this memory, and also erases the storage location of the transmission stop data in the RAM 20, that is, the memory between the area, from the RAM 30 to free the area, and in this way, the purpose data can be stopped from being sent to an external device.

In the configuration of the present invention shown in FIG. 1, the operation when a signal is input will be explained with reference to the flowchart shown in FIG.

First, it is determined whether or not there is an interrupt signal for interrupting transmission from the interface IP or IF2, and if there is an interrupt signal for halting transmission (YES in step 102, that is, "Yes").
), the type of data to be stopped is interface I.
FI Mana reads from I F 2 (step 103)
. Next, it is determined whether transmission of that type of data can be stopped (step 104). In other words, the data is not currently being sent and the data is stored in the RAM for storing the sending order.
40, the transmission can be stopped (YES in step 104), but if the data has already been moved to the working RAM 10 for transmission, the transmission cannot be stopped (No in step 104, i.e. “No J).

If it is possible to cancel the transmission (YES in step 104),
By erasing the memory regarding the transmission order from the RAM 40 (step 105) and erasing the information regarding the corresponding area stored in the RAM 30, the storage area in the RAM 20 in which the data whose transmission was canceled is stored is released. (Step 106).

After the storage area for the data to be stopped is released,
Or, if you do not want to cancel the transmission (N in step 102)
O or “No” and No of step 104);
It is determined by checking the RAM 30 for data storage area management whether or not the area of the RAM 20 for storing the processing results of signals input from a control device, a monitoring terminal, etc. is vacant (step 107). If the area is empty (YES in step 107), it is determined whether there is an input signal from a control device, a monitoring terminal, etc. by checking the interface IP, ~IF, and if there is an input signal, (YES in step 108)
), the input signal is processed to create the sending data (step 109), the data storage area in the RAM 20 for storing the sending data is secured by registering it in the RAM 30 for data storage area management (step 110), R
The processing result is stored in the AM 20 as transmission data (step 111), and information regarding the storage area of the data stored in the RAM 20 (for example, the start address and data length), the data type, etc. is stored in the RAM 40 for storing the transmission order (step 111). 112). In this case, the order of data transmission is, for example, the order of storage in the RAM 40.

When checking the RAM 30 for data storage area management, if it is determined that the area of the RAM 20 is not free (No in step 107), there is no area to store new processing results, and the RAM 20 is used to store the data to be sent. Therefore, it is next determined whether data can be sent to the corresponding external device (step 114). Furthermore, even if the area of the RAM 20 is empty, there is no input signal (No in step 108) and the R
If it is determined that there is data to be sent by checking the AM 40 (YES in step 113), it is similarly determined whether or not data can be sent to an external device.

The state of the interface IF4 is checked, and if, for example, no failure of the external device is detected, it is determined that data can be sent to the external device (YES in step 114).
, a data sending command is issued (step 115), and this causes the RAM 20 for storing sending data corresponding to the first order stored in the RAM 40 for storing sending order.
data is sent to the interface IF. When it is determined that the data transmission has been completed (YE in step 116),
S), Next, the memory of the sending order storage RAM 40 corresponding to the sent data is erased (step 117), and the data storage area management RAM 40 corresponding to the sent data is erased.
Erase the memory contents of M30 and transfer it to RAM 2 for storing sending data.
Free the 0 data storage area.

[Effects of the Invention] As described above, according to the present invention, when the type of processing result is stored in the second storage means and transmission of the transmission data already stored in the first storage means is to be stopped, the specification means By inputting the type, the second storage means is searched for something equivalent to this type, and this memory is erased. Therefore, it is possible to easily prevent the data whose transmission is to be stopped from being transmitted to an external device. This has the effect that it can be canceled with .
