Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a transmission procedure performed between a terminal such as a fire detector or repeater in disaster prevention equipment and a receiving section such as a receiver or repeater.

[Background technology] In fire alarm equipment, it is necessary to promptly transmit predetermined information from terminals such as fire detectors and repeaters to receiving sections such as receivers and repeaters. There is a desire to shorten as much as possible the time required for a receiving unit to understand the status of a terminal.

In order to meet this demand, disaster prevention equipment that employs system polling, point polling, and selecting has been proposed.

In other words, terminals such as fire detectors and repeaters are connected to receiving parts such as receivers and repeaters, multiple terminals are divided into multiple groups, polling is performed for each group, and the group containing the terminal whose status has changed is polled. At the return timing, system polling is performed to respond to the receiving unit, polling is performed for each terminal in the group that responded to the receiving unit in the system polling, and at the return timing of the terminal whose status has changed, it responds to the receiving unit. Disaster prevention equipment has been proposed that performs point polling, collects predetermined information from terminals that respond to the point polling, and/or selects to send control commands to specific terminals.

[Problem to be solved by the invention] In the disaster prevention equipment proposed above, when a command common to multiple terminals is sent to each terminal, such as fire recovery, district sound stop, storage recovery, etc., each terminal is individually By polling, the called terminal receives the above command.

Therefore, the proposed disaster prevention equipment has a problem in that it takes a long time to send the common command to each terminal.

[Means for solving the problem] The present invention divides a plurality of terminals into a plurality of groups, polls each group, and performs system polling that responds to the above-mentioned receiving unit at the time of return of a group having a terminal whose status has changed. , polling each terminal in the group that has responded to the receiving section, and responding to the receiving section at the return timing of the terminal whose state has changed, and collecting predetermined information from the terminal that has responded to the receiving section; and/or a specific terminal. When transmitting a control command to a plurality of terminals, the receiving section simultaneously transmits a common command to a plurality of terminals during system polling.

[Operation] According to the present invention, during system polling, the receiving unit simultaneously sends a common command to a plurality of terminals, so that the time required to send the common command to each terminal is shortened.

[Embodiment] FIG. 1 is a diagram showing an example in which terminals are divided into groups in an embodiment of the present invention.

In this example, the terminals Tl1-T44 are connected to the receiver RE as an example of the receiving section, and the terminals 'rtt-T44 are
Four groups G1. It is divided into G2, G3, and G4. Note that in the above embodiment.

Although the number of terminals in one group is set to 4, the number may be other than 4, and the terminals may be divided into groups other than 4.

Each of the terminals Tll to T44 is a fire detector (analog type, etc.) or a repeater, and this relay has monitoring equipment (fire detector, etc.) or controlled equipment (district bell, fire door, smoke prevention device, etc.). dampers, etc.) are connected.

The receiver RE polls the terminals Tll to T44 in a system polling, point polling, and selecting mode, which will be described later, to collect predetermined information from predetermined terminals and to control the predetermined terminals.

Here, system polling does not poll each of the terminals Tll to T44 one by one, but polls the terminals Tll to T44 one by one.
44 into four groups, poll each group, give a return timing to each group, and at the return timing of a group that has a terminal whose status has changed,
Polling in response to the receiver RE.

Point polling polls each terminal in the group only for the group that responded to the receiver RE in system polling, gives a return timing to each terminal, and returns the signal to the receiver RE at the return timing of the terminal whose status has changed. This is a poll that responds.

Selection involves collecting predetermined information from terminals that responded to the receiver RE during point polling, or transmitting a predetermined i'tijil command to the terminal that responded to the receiver RE during point polling or to any terminal.

Further, during the system polling, the receiver simultaneously sends a common command common to a plurality of terminals to a plurality of terminals. These common commands include, for example, fire restoration commands (commands to restore terminals such as detectors and repeaters that sent out fire signals, and terminals such as repeaters that ring district bells to normal monitoring status), Restoration command (command to restore terminals such as fire detectors and repeaters that sent out fire signals in order to perform storage operation to determine whether the fire condition continues for a specified period of time), district sound ! There are stop orders (orders to stop ringing district bells), etc.

Furthermore, when the receiver sequentially calls multiple terminals to request transmission of specific information and receives the specific information from the terminals, it is assumed that there is no disconnection between the receiver and the terminals. to decide. In addition, the type information is used as the above specific information, and the type information received by the receiver from the terminal is compared with the type information of the terminal registered in the receiver, and if the two types of information do not match, the corresponding Determine that the device type has changed.

FIG. 2 is a diagram showing an example of the operation of the above embodiment.

The operation progresses from the upper left to the upper right of this figure 2, and from the right end, the operation progresses to the left end of the next stage below, and the processing proceeds sequentially as described above. The upper part indicates the operation of the receiver RE, and the lower part of the horizontal line indicates the operation of the terminal (or group).

Further, in FIG. 2, a broken line frame indicates that the message was not returned at the return timing, and a thick line frame indicates that the message was returned at the return timing. In other words, the thick line frame indicates a terminal whose state has changed compared to immediately before the return timing (or a group including terminals whose state has changed).

First, at Pl in FIG. 2, the receiver RE performs system polling. In other words, the receiver RE sends an address 5PAD indicating system polling and a status information return command CMI to return status information to the groups G1 to G4. Set the timing for returning status information to groups 01 to G.
4 in sequence. Each of groups 01 to G4 is
Only when the status of a terminal in its own group changes, it responds by returning status information etc. to the receiver RE at its own return timing. In the example shown in FIG. 2, since the state of terminal T23 has changed, only group G2 is connected to receiver RE.
respond to. This causes the receiver RE to
The state of any of the terminals T21 to T24 belonging to changes.
It can be understood that it has status information to be sent to the receiver RE.

Next, in P2, point polling is performed, that is, the receiver RE sends the address CAD of the group to be polled and the status information return command CMI to the terminals belonging to the group. In the case of the above example, address CAD (2) and status information return command CMI are sent to terminal T.
21-T24. Then, the terminals 721 to T24 are sequentially given timing to send back the status information. Each terminal responds by returning status information etc. to the receiving aRE at its own return timing only when the status of its own terminal has changed. During the above point polling, terminal T
Since the status of T23 has changed, only terminal T23 receives the data! Respond to I&RE. This allows the receiver RE to understand that the state of the terminal T23 has changed and that the terminal T23 has state information that should be sent to the receiving allH.

Next, in P3, selecting is performed, that is, the receiver RE selects the address SA of the terminal that received the response signal.
D and a status information return command CMI are sent. In the above example, since a response signal was received from terminal T23, receiver R
E sends the terminal address SAD (23) and a status information return command CMI. On the other hand, the terminal T23 sends its own address SAD (23) and the data DA it wants to send.
(for example, a fire signal) to the receiver RE.

When the receiver RE receives the data DA, it sets its own address S.
AD (23) and the received data DA are sent, the terminal T23 receives the above data DA, and the terminal T23 sends the data DA sent immediately before and the data received at that time I)A
If both data match, the terminal T23 sends the data DA to the receiver RE again. 5 If the data DA received by the reception aRE the first time and the data DA received the second time match, the data DA is transferred to the terminal T23.
It is recognized that this is indeed the data that was sent.

The receiving aRE then performs necessary processing based on the received data DA.

As a result of determining the data DA received by the receiving 4jlRE through the above selection, if it is determined that there is a fire, in P4, the n-th controlled device a is operated (
(for example, ringing the district bell), in the above example,
The receiving aRE sends out the address 5aD(n) of the terminal Tn and the ringing command CM3.

Then, when the terminal Tn is called by the receiver RE and receives the district bell ringing command CM3, the terminal Tn returns the self address SAD (n) and the received ringing command CM3 to the receiving fiRE for confirmation. When the terminal Tn is called again from the receiver RE and receives the same ringing command CM3 from the receiver RE again, the terminal Tn controls the ringing of the district bell for the first time, and also sends control state data DA and self address SAD (n ) is sent back to the receiver RE.

After this, the system returns to normal and repeats the system polling described above.

Next, common command processing will be explained.

At P6 in FIG. 2, when the operator inputs a fire restoration command, which is one of the common commands, into the receiver RH, the receiver/receiver RE sends out an address 5PAD indicating system polling and a fire restoration command CM4.

As a result, the monitoring terminal returns to the monitoring state, the control terminal stops controlling (for example, in the case of a district bell, it stops ringing), and the normal monitoring state is restored.

In the above example, a common command such as a fire restoration command is sent only once, but if it is sent multiple times (for example, 5 times) and the same common command is received a predetermined number of times (for example, 3 or more times),
It may be determined that a correct common command has been received, and the content of the common command may be executed, thereby preventing malfunctions due to transmission errors.

Note that in the above example, point polling and selecting are each executed twice, but this is to prevent erroneous transmission due to induced noise or the like.

Next, the operation of inspecting the main transmission line for disconnection will be explained.

At POl in FIG. 2, system boring is performed once, and then selection is performed to check for disconnection in the main transmission line to terminal Tll.

That is, the receiver RE receives the address SAD of the terminal Tll.
(11) and specific information return command CM2, terminal T
ll receives its own address SAD (11) and specific information (in this case, type information CL indicating the type of terminal) aR
Return it to E. When receiving the type information CL from the terminal Tll, the receiver RE determines that the main transmission line from the receiver RE to the terminal Tll is not disconnected.

Then, after performing system polling once and confirming that there is no terminal whose status has changed, the same disconnection test as above is performed for terminal T12. A disconnection test is performed from the terminal to the terminal, and system polling is performed once at a time. In this system poll,
If any group responds, point polling is of course performed for that group.

Perform the necessary selection.

Type information CL includes monitoring repeater, control repeater,
There is information indicating monitoring and control repeaters, analog fire detectors, etc. In this way, when the receiver collects the type information as the specific information, the receiver can know whether the terminal is connected or not, and at the same time, know that the type of the terminal has been changed. In the above example, selection for disconnection determination is performed every time system polling is performed, so system polling must be performed 16 times to monitor all terminals T11 to T44.

Note that disconnection determination may be performed every time system polling is performed a predetermined number of times, disconnection determination may be performed at predetermined time intervals, and selection of multiple terminals for disconnection detection may be performed at one time. Also, if disconnection determination selection is performed twice in succession for the same terminal, erroneous determinations due to induced noise can be prevented. Further, the specific information may be information other than type information, such as a specific code.

Next, the operation of the above embodiment will be explained.

FIG. 5 is a diagram showing a system flowchart of the receiver RE in the above embodiment.

First, initial settings are performed (SO), and it is determined whether or not there is a control interrupt (si).
This is an interrupt that occurs when there is an input from F or due to selection during monitoring. If there is no control interrupt, a system poll is performed (32) and if there is a state change in this system poll (i.e.
If there is a group that has sent a response signal) (S3), point polling is performed (S4), and if there is a state change in this point polling (that is,

If there is a terminal that has sent a response signal) (S5), selection is performed (S6).

If there is no change in the state when system polling is performed, selection for disconnection determination (operation for determining whether terminals T11 to T44 are connected to the receiving 41RE) is performed (S7). This disconnection determination selection is performed as follows: When a system poll is run and there is no response group,
The terminals Tll to T44 are discriminated one by one.

In Sl, if there is a control interrupt, the common instruction (
If there is no command common to multiple terminals, such as a fire recovery command, storage restoration command, or district a#s stop command, which is determined by the presence or absence of memory in the RAM 14 (38), selecting (S9) is performed. Individual control is performed based on the contents stored in the RAM 15.

If it is a common command in S8, system polling (
S2) is performed and control is performed using the common command stored in the RAM 14.

Figure 6 shows system polling [S2] in Figure 5.
It is a flowchart specifically showing.

First, since control interrupt operations by common instructions are not required (sii), 5PA indicating system polling is
The receiver RE sends D and status information return command CMI (S12), sets the terminal group number g to "O" (S13), and sends the terminal group number g to "O" (S13), and then sends the status information return command CMI for a predetermined time period corresponding to the return timing time of group G1. When (S

Increment S18), SL4 to S16 above
and Si2 are repeated until the terminal group number g reaches the final terminal group number G (S17) and return.

On the other hand, in S11, if there is an input command from the operation unit OP (there is a control interrupt command), the command code is read from the RAM 14 in which the control interrupt information is stored (519), 5PAD and the command If the command code sent at this time is a fire recovery command (S21), the stored contents of RAMI 4 and RAM 15 are unnecessary and should be erased (522), and the control interrupt code is sent (320). 523) and return.

In S21, if the instruction code is not a fire recovery instruction, the corresponding instruction in the RAM 14 is erased to prevent retransmission.
24) If the terminal control information is not stored in the RAM 15, the control interrupt is turned off and the process returns. RAM1
If there is memory content in 5 (S25), the process returns without turning off the control interrupt.

Figure 7 shows point polling (S4) in Figure 5.
2 is a flowchart showing specific operations.

First, a fire detector is connected to a group (in the attached flowchart, the group is referred to as a "group" for simplicity) to which the terminal whose state has changed is stored in the RAM 12. It is determined whether there is a group to which the monitoring terminal such as a repeater belongs, and if there is a group to which the monitoring terminal belongs (331), the number g71 of that group is determined.
533), sets the point polling execution count k to "1" (S34), sends the address and status information return command CMI of the group, and sets the terminal number m of the group to "1". "Nishiku S3
5, 336), when a response signal is received from terminal m within a predetermined time (S37.338), it is determined whether it is the first polling or the second polling (S41).

If it is the first polling, the fact that a response signal has been received from the m-th terminal is stored in the RAMI 542), and the above operation is repeated until the final number of terminals in the group is reached (339, 340).

Change the number of point polling executions k to "2" S

Since this is the point polling for the second time (S41), the judgment in S43 is performed, and if a response signal is received from the terminal m in both the first and second polling (S43), the terminal number n corresponding to the terminal number m is determined. is stored in the RAM 13 (545), m is erased from RAMI 1 (S44), and when the above operation is repeated until the final terminal of the group, the corresponding g is erased from the RAM 12 (348), and the process returns. Note that if there is no group to which the monitoring terminal belongs in S31, the first number g of the group to which point polling is to be performed is read from the RAM 12 (S32).

In the above explanation, the number of times point polling is executed is 2.
However, the number of times the point polling is performed may be set to 1 or 3 or more times, or if it is not necessary to give priority to the point polling for the group to which the monitoring terminal belongs, the number of times the point polling is performed is stored in the RAM 12. It is sufficient to perform point polling on the groups sequentially. In this case, 331 and 333 are omitted in FIG. 7.

Then, it waits for a received signal for a predetermined time (358, 559), and when there is a received signal (358) and the first received data and second received data are the same, the received data is stored in the RAM 16 ( S60.561), please delete the corresponding data in RAMII and the corresponding n in RAM13.S62.3

Then, wait for the above received signal for a predetermined time and receive it (
S77, 378), when the control command and the control state of the terminal received for the second time match (S79), in order to later judge whether or not the contents of the sent command and the resulting control result match. , stores the sent instruction code and terminal number n in the RAM 17, and erases the corresponding terminal number n and instruction code from the RAM 15 to prevent retransmission (579

restores, sets RAM21 to 23 to the initial state, and returns (U22 to U24). Also, if it is an accumulation restoration command, restores the FSR, and if it is a district sound stop command, returns L.
The AC is controlled to turn off (U25 to U28).

FIG. 13 is a flowchart showing a specific example of the point processing (U5) in FIG. 11.

When performing point processing, set the terminal number m in the group to "0" and if it is stored in the RAM 23,
After a predetermined time has elapsed, when the terminal number m matches the terminal number Mk in the own group, a response signal is sent (U31 to U36). Note that the terminal number m is the own terminal number Mk in the group. Consistent with, if not.

Increment m by 1 (U35).

FIG. 14 shows the selection process (U
7) is a flowchart showing a specific example.

First, if the command specified by selecting is the status information return command CMI, the status information is read from the RAM 23, the self address and the status information (data DA) are sent (U41-U43), and the received signal is received and received. If it is a self-address, read the status information from RAM23 U44~
U46) If it matches the received data, it resends the self address and status information and erases the status information in the RAM 23 for the first time (U47 to U49). Note that if the received signal is not received, or even if it is received, the self address is If they do not match, the process waits for a predetermined time (U50).

After U49, the corresponding instruction in the RAM 21 is deleted (U67), and the process returns.

In U41, if the status information return command is not received, the number of execution times k of the selecting process is set to 1, and if the specific information return command CM2 is received, the type information is read from the ROM 22, and the self address and type information CL are set. Then, the number k of executions of the selecting process is incremented by 1, and when the received signal is received and it is the own address (U56 to U38), the process returns to U52.

On the other hand, if U52 receives a control command instead of a specific information return command and the number of times point polling is executed is one, it sends out the self address and the received control command CM3,
Store the received control command in the RAM 21 (U59 to U
62) When receiving a control command, if the number of executions of the selecting process is 2 (U60), when the first and second control commands match, the command contents are set in the corresponding circuit and the output circuit is The control state is read from , the self address and the read control state information (data DA) are sent out, the corresponding command is erased from the RAM 21 (U63 to U67), and the process returns. Note that U57 waits for a predetermined period of time for the second signal to be received (U88), and if the second signal is not received, the RAM
Delete the corresponding instruction of No. 21 and return U67).

[Effects of the invention] According to Suekan 11, terminals such as fire detectors and repeaters are connected to receiving sections such as receivers and repeaters, the plurality of terminals are divided into plural groups, and system polling and point polling are performed. In disaster prevention equipment that performs the following, the effect is that the time required to send a common command to each terminal is shortened.
