Abstract

PURPOSE:To shorten a transfer time by providing an all table transfer protocol which transfers all changed interlocking tables to all repeaters and a changed table transfer protocol which transfers only changed interlocking tables to corresponding repeaters. CONSTITUTION:Each block is provided with a fire sensor 1, smoke preventing and excluding device 3, and an alarm region bell 2. When a signal IPLtheta from a receiver 5 is received by a repeater 4, the repeater 4 returns the ACK signal; and when IPL (data) is received, it returns the END signal. The repeater 4 writes data of interlocking tables in an incorporated storage element Contents of interlocking tables are three sets of signal 'fire-one line one address', signal extension 1 'fire-one line one address' and signal extension 2 'fire-one line one address'. Thus, only changed interlocking tables can be transferred from the receiver to objective repeaters 4 to shorten the transfer time.

For interlock control, the smoke prevention equipment 3 is controlled in conjunction with the sensing data of the fire detector 1, the function data of the smoke prevention equipment 3, and the alarm of the fire detector 1 during distributed processing in the repeater 4. Interlocking tables consisting of data etc. can be set by switches or written to EPROM,
It also includes a fixed interlocking table written in the diode matrix, or a variable interlocking table written in RAM, power backup RAM, or non-volatile memory.

However, when using the former fixed type interlocking table, when changing the interlocking table, it is necessary to directly change the interlocking table of the target repeater 4, and the repeater 4
This was very inconvenient when there were a large number of machines or when there was little time to make changes.

Furthermore, when the latter variable type interlocking table is used, it is convenient because the interlocking table can be transferred to the repeater to be changed by operation from the receiver 5.

As this transfer method, for example, the receiver 5 uses an EPROM
If there is a change in the sensitivity of the fire detector 4 or the interlocking control of the smoke prevention equipment 3, the EPR
After changing the contents of the OM, replace the EPROM in the receiver 5 and transfer the interlocking table to the repeater 4 by operating the receiver 5. For example, when changing the interlocking table of 10 points or less, A method has been adopted in which non-volatile memory is used to respond to emergency interlock table changes without replacing the EPROM.

[Problems to be Solved by the Invention] However, in this conventional example, when transferring the interlocking table from the receiver 5 to the repeater 4, it is necessary to transfer each interlocking table to all the repeaters 4, and the repeater In case of a disaster prevention system with a large number of 4's or a large number of interlocking table contents, the transfer time of the interlocking table becomes a big problem.

The present invention has been made in view of the above-mentioned problems, and its purpose is to shorten the transfer time by transferring only the changed interlocking table when the interlocking table is transferred from the receiver to the repeater. The purpose of the present invention is to provide an interlocking table transfer method for a disaster prevention system.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention includes a plurality of fire detectors for detecting fire, a district bell for notifying the occurrence of a fire, and a system for detecting the spread of smoke generated in the event of a fire. It consists of smoke prevention equipment, fire detectors, district bells, repeaters that monitor and control the smoke prevention equipment, and receivers that centrally monitor these relays. Transfers an interlock table from the receiver to the repeater, which includes data such as sensor detection data, function data of the smoke control equipment, and data for interlocking control of the smoke control equipment when a fire detector fires during distributed processing at the repeater. In the disaster prevention system, when the contents of the above-mentioned interlocking table are changed at the receiver, there is an all-table transfer protocol that transfers all the changed interlocking tables to the repeater, and a changed table transfer protocol that transfers only the changed interlocking table. It is characterized by

[Operation] The present invention has an all-table transfer protocol that transfers all changed interlocking tables to a repeater when the contents of an interlocking table are changed in a receiver, and a changed table transfer protocol that transfers only the changed interlocking table. Therefore, when a small number of interlocking tables are changed at the receiver, only the changed interlocking tables can be transferred from the receiver to the target repeater, thereby reducing the transfer time.

[Example] The present invention will be explained below with reference to Examples.

The disaster prevention system used in the present invention uses a system similar to the distributed disaster prevention system shown in FIG.
The format of the signal data is different as shown in FIG. In other words, as shown in the figure, the synchronization signal (SVN
), repeater address, IPL code, type code, data to be transferred 0..., and two CRC codes in the data format of rlPLJ signal,
In the type code, all points start indicating transfer of all points of the interlock table in the IPL sequence, change start indicating transfer of only the changed interlock table, and IPL end indicating end of IPL can be set.

The IPL sequence for transferring the interlocking table is the second one.
The sequence shown in the figure is adopted. Furthermore, the memory allocation of storage elements such as a rewritable RAM and a non-volatile memory built into the repeater 4 is configured as shown in FIG.

FIG. 3(a) is a zero-order table, and this zero-order table contains the number of fire managements and the first table block N.

FIG. 3(b) shows the primary table, and the block N
The area is divided by O, and the area of each block number contains the address number of the connected line No. 1 connected equipment (fire detector 1, smoke prevention equipment 3, district bell 2, etc.), and the secondary table page number (e.g. 4 pages worth) is written on it.

FIG. 3(c) shows a secondary table, and a detailed table corresponding to the above page number is written in the area of this secondary table, and the area of each page number is 12.
8-byte attribute data and interlock information are written.

In addition to this, there is an area to write a 2-byte checksum,
The area of the page number in the primary table where the number of the secondary table being used is written, and the area of the total page number of the secondary table where the number of secondary tables being used is written are shown in Figure 3 (d) to (f). Assigned as shown.

Next, the method of the present invention will be explained based on the rPL sequence shown in FIG.

First, when repeater 4 receives an IPL with all points started,
The repeater 4 returns the rENDJ signal shown in FIG. 5(c), starts the IPL sequence, clears each of the 0th to 2nd tables to 0 in the built-in storage element, and clears the 1st table block. Writing is performed with the number set to 1 and the secondary table total page number set to 1.

Next, as shown in FIG. 5(e), from the receiver 5 to FIG. 6(e),
) When the repeater 4 receives the rlPLO signal shown in FIG. 6(b), the repeater 4 returns the [^CK, signal shown in FIG.
After that, when receiving the "Npt (data)" signal from the receiver 5, the repeater 4 sends r END.

send back a signal. Then, the repeater 4 writes the data of the interlock table into the built-in storage element as follows.

Here, the contents of the interlocking table are three points: "Fire-1 line 0 address J signal, F fire-[jjl line! address" signal, and "Fire-1 line 1 address J signal extension."

First, in the case of the [Fire - 1 line 0 address] signal, write the primary table block No. in the fire area of the 0th table, and write the line No. in the block No. of the primary table.
= 1, Address No. = 1. Secondary table page No. = 1
and then write 1 to page No. of the secondary table.
Write 28 bytes of data to primary table block N
Write 2 in the area o, and write 2 in the secondary table total page number area.

In the case of the [Fire - 1 line 1 address] signal, 5 line No. = 1, address No. 0 = in block No. 2 of the primary table.
1. Further page N of the secondary table into which the secondary table page No. 2 is written respectively.

Write 128 bytes of data to 2, write 3 to the primary table block number area, write 3 to the secondary table total page number area, [Fire-1
In the case of "Line 1 Address" signal expansion, write secondary table page No. 3 to block No. 2 of the primary table, write 128-byte data to page No. 3 of the secondary table, and write 128-byte data to the area of primary table block No. 4 is written in the secondary table total page number area.

Relay f? When i4 receives the rlPL (end) signal from the receiver 5, it returns an r END signal and ends the rPL sequence.

Next, if the repeater 4 receives the IPL with the change point start, the repeater 4 returns the r_END, signal and starts the IPL sequence.

Then, the r fPLo J signal from the receiver 5 is transferred to the repeater 4.
When received, repeater 4 returns the ^CKJ signal and
If PL (data) is received, r END signal is returned. Then, the repeater 4 writes the data of the interlocking table in the built-in memory element as follows. Here, the contents of the interlocking table are "Fire-1 line 1 address" signal, "Fire-line l address" signal extension 1, There are three points: "Fire - 1 line 1 address" signal extension 2.

First, in the case of the [Fire - 1 line 1 address] signal, the first block number of the primary table is read from the 0th table area. From the read first block number of the primary table, time 1! No, select the matching address No., and clear the secondary table pages No. 1 to No. 4 of the matched primary table block to 0.

Next, the secondary table page N of the primary table.

Write the secondary table total number value in area 1,
Furthermore, 128 bytes of data are written in the secondary table (at the memory address of the secondary table total page number), and the secondary table total page number is incremented by 1.

[Fire - 1 line 1 address] In the case of signal extension 1, the first block number of the 1st table is moved from the 0th table area.
Select the line number and address number that match from the first block number of the read primary table, and write the secondary table total number value in the secondary table page No. 2 area of the matched primary table block. Write, further write 128 bytes of data to the secondary table (at the memory address of the secondary table total page number), and write the secondary table total page number]
-1 and write.

In the case of "Fire - 1 line 1 address" signal extension 2, the first block number of the 1st table from the 0th table area
Select the line number and address number that match from the first block number of the read primary table, and set the secondary table total number value in the secondary table page No. 3 area of the matched primary table block. Furthermore, write 128 bytes of data to the secondary table (at the memory address of the secondary table total page number), and add the secondary table total page number.
1 and write.

When the repeater 4 receives the rlPL (end) signal from the receiver 5, it returns the rENDJ signal and ends the IPL sequence.

In this manner, in the IPL sequence of the present invention, there is a change point start in which only the changed interlock table is transferred, and an all point start in which all interlock tables are transferred to all repeaters 4 as in the conventional case. When a change is made due to EPROM replacement, the IPL starts at all points, and when a small number of interlocking tables using non-volatile memory are changed in the receiver 5, the IPL starts at the change point.
Each sequence is executed separately.

[Effects of the Invention] In order to achieve the above-mentioned objects, the present invention provides a plurality of fire detectors for detecting fire, a district bell for notifying the occurrence of a fire, and preventing the spread of smoke generated in the event of a fire. The fire detector is composed of smoke prevention equipment that monitors and controls these fire detectors, district bells, repeaters that monitor and control the smoke prevention equipment, and a receiver that centrally monitors these relays. Transfers an interlocking table from the receiver to the repeater, which consists of data such as sensing data, function data of the smoke control equipment, and data for interlocking control of the smoke control equipment when a fire detector fires during distributed processing at the repeater. In a disaster prevention system, when the contents of the above-mentioned interlocking table are changed on the receiver, there is an all-table transfer protocol that transfers all the changed interlocking tables to the repeater, and a changed table transfer protocol that transfers only the changed interlocking table. Therefore, when a small number of interlocking tables are changed at the receiver, only the changed interlocking tables can be transferred from the receiver to the repeater, which has the effect of shortening the transfer time.
