Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention detects a terminal device in which a plurality of terminal devices such as a fire detector and a repeater are connected to a receiving section, an address is given to each terminal device, and the state has changed. Regarding fire alarm equipment.

[0002]

2. Description of the Related Art In a fire alarm facility in which a plurality of terminal devices such as a fire detector are connected to a receiver, an address is given to each terminal device, and the terminal device whose state has changed is detected, For the purpose of allowing the receiving unit to quickly grasp what has changed in state in JP-A-2-20159.
The fire alarm system shown in No. 7 has been proposed.

In this conventional example, the terminal equipment is divided into a plurality of groups, and the timing at which the terminal equipment responds to the receiving section is made different for each group of the terminal equipment, and the terminal equipment whose state has changed responds to the response timing of the group to which it belongs. , The timing at which the terminal device whose state has changed responds to the receiving unit (performs system polling), and then responds to the receiving unit for each terminal device in the group to which the terminal device responding to the receiving unit in this system polling belongs. The terminal device whose state has changed responds to the receiving unit at the response timing assigned to itself (performs point polling), calls the terminal device that responds to the receiving unit at this point polling, and from this terminal device, The receiving unit collects information (selection).

In this way, the operation for obtaining the predetermined information is executed only for the terminal device that has changed the state, and the operation for obtaining the information is not executed for the terminal device that does not change the state. It is possible to grasp the state change of the terminal device in a shorter time than sequentially obtaining the predetermined information.

[0005]

By the way, as the terminal equipment connected to the receiver, there is a transmitter in addition to the fire detector and smoke prevention equipment, and when the transmitter operates, its operation is performed. It is obligatory that a fire alarm is generated within a predetermined time from the start and the response lamp of the operated transmitter is turned on. However, if a large number of terminal devices are installed and the number of terminal devices that have changed in state is large, the fire alarm may not occur within the predetermined time.

That is, for example, when 256 terminal devices are divided into, for example, four groups, and polling is performed for each group, and all of the four groups respond (this includes a state change not directly related to a fire). To)
It is necessary to perform point polling for all of the four groups, and if there are many terminal devices that have changed states within one group, select all of the terminal devices that have changed states and obtain the predetermined information from each terminal device. It will be collected by the receiver.

When the operated transmitters belong to, for example, the fourth group, information is sequentially collected from the terminal devices (terminal devices whose states have changed) belonging to the first group, and therefore the first There is a problem that it takes a long time to collect information about the transmitter after starting information collection from the terminal devices belonging to the group.

The same applies to fire detectors, gas detectors, etc., which are connected at the same time as the controlled terminal devices, and information is collected from the interlocking terminal devices such as smoke-prevention devices belonging to the first group. There is a problem that it takes a long time to collect information about the fire detector and the gas detector whose state has changed after starting the.

According to the present invention, for example, even in a large-scale fire alarm system, when a terminal device of a high priority type such as a transmitter is operated, the receiving section quickly grasps the fire information from the transmitter or the like. The purpose is to provide a fire alarm system that can be used.

[0010]

DISCLOSURE OF THE INVENTION According to the present invention, a fire alarm facility for detecting a terminal device in which a terminal device such as a fire detector is connected to a receiver, an address is given to the terminal device, and the state of which has changed is transmitted. The special response timing of the specific terminal equipment that only the specific terminal equipment such as the machine responds is set during the normal system polling and the normal point polling, and when the response is received at the special response timing of the specific terminal equipment, It performs system polling or point polling for specific terminal equipment and selecting.

[0011]

According to the present invention, the special terminal device special response timing to which only a specific terminal device such as a transmitter responds is set during normal system polling and normal point polling, and when there is a response at the special terminal device special response timing. Immediately, system polling for specific terminal equipment or point polling for specific terminal equipment, and selecting are performed, so when a large-scale fire alarm facility operates, the transmitter, etc. The receiver can quickly grasp the fire information.

1 is a time chart showing an embodiment of the present invention, FIG. 2 is a wiring diagram of a fire alarm system to which the above embodiment is applied, and FIG. 3 is another wiring diagram of the above embodiment. It is a time chart which shows operation.

In the example shown in FIG. 2, a fire receiver RE (smoke type, thermal type, flame type,
Gas type, odor type fire detector), transmitter P, repeater R
Various terminal devices such as P are connected, different addresses are given to these terminal devices, and these terminal devices are divided into four groups G0, G1, G2, and G3.

The group G0 includes three fire detectors S and one transmitter P, the group G1 includes three fire detectors S and one transmitter P, and the group G2 includes three fire detectors S and one transmitter P. Two fire detectors S, one relay RP, and one transmitter P belong, and three fire detectors S and one transmitter P belong to the group G3. The address of each terminal device is sequentially assigned address 0, address 1, address 2, ..., Address 15 from the first address of the group G0. A plurality of ON / OFF type general sensors (having no address) that send out a fire signal due to a short circuit between wirings are connected to the repeater RP of address 10. In this example, the number of terminal devices in one group is 4
However, the number of groups may be other than four, and the number of groups may be four, but the number of groups may be divided into groups other than four.

Also, the receiver RE has a district acoustic connection line L.
2, a plurality of district bells B are connected, a plurality of smoke-proof and smoke-proof connection lines L3 are connected to a plurality of smoke-proof equipment ER, and a plurality of display devices are connected through a display device connection line L4. .

In the above embodiment, no address is given to the control system terminal equipment such as the district bell B, the smoke control equipment ER, the display equipment AN, etc., and the individual signal line L2 for each terminal equipment or each system. Controlled by turning on / off L4 (so-called P wiring connection), the monitoring system terminal devices such as the fire detector S, the transmitter P, and the repeater RP are serially transmitted by the two common power source / signal line L1. An address is designated by such as, and can be controlled individually (so-called R wiring is connected).

The receiver RE is usually a system poller,
During normal point polling, a special terminal device special response timing (transmitter slot) where only the transmitter and others respond is provided, and when there is a response at this special terminal device special response timing, the system polls for the specific terminal device immediately. Alternatively, it executes point polling for specific terminal equipment and selecting.

Here, "normal system polling" means
It is a polling that checks for each group only whether or not there is a terminal device whose state has changed, rather than specifying the terminal device whose state has changed in advance by dividing the terminal device into multiple groups, that is, receiving The timing of responding to the device RE is different for each group of terminal devices, and at the response timing assigned to the group to which the terminal device whose state has changed, the terminal device whose state has changed simultaneously responds to the receiver RE (for example, pulse Polling). In addition, in "normal system polling", a transmitter special response timing (transmitter slot) where only the transmitter responds is provided in addition to general terminal equipment, and there is a transmitter whose status has changed. Only trying to figure out.

Further, as with the transmitter, there is a fire detector and a gas detector that need to know the state change promptly. Considering a specific terminal device as a concept including these, "normal system "Polling" divides a plurality of terminal devices into a plurality of groups, sets a group device response timing for each terminal device in which one or more terminal devices in the same group simultaneously respond to the receiving unit, and Different response timing for each group,
When the state of the terminal device changes, at the time of the group response timing for the terminal device of the group to which the terminal device whose state has changed, the terminal device whose state has changed is a polling response to the receiving unit, and during this normal system polling,
A special terminal device special response timing is provided. The specific terminal device special response timing is determined by dividing the specific terminal device among the terminal devices into at least one group and
This is a timing in which two or more specific terminal devices simultaneously respond and are set at timings different from the terminal device group response timing and the terminal device individual response timing.

Then, when there is a response to the receiving section at the special terminal device special response timing, the specific terminal device whose state has changed is immediately detected by the system polling for the specific terminal device and the point polling for the specific terminal device which will be described later. It is like this.

The "normal point polling" is a polling for specifying a terminal device that responded to the normal system polling (that is, a polling for specifying a terminal device that has changed state), and a group that responded to the receiver RE in the normal system polling. The terminal equipment belonging to the receiver R
Receiving in which E calls, terminal devices in the group have different timings for responding to the receiver RE (for example, different timings for responding by sending a pulse), and terminal devices whose states have changed are assigned to themselves. Polling that responds to the receiver RE (for example, responds by sending a pulse) at the timing of responding to the device RE. Also,
Even in "normal point polling", a special transmitter response timing (transmitter slot) in which only the transmitter responds is provided, and only the presence of a transmitter whose status has changed is known. .

That is, "normal point polling"
In the normal system polling terminal device group response timing, each terminal device in the group to which the terminal device responding to the receiving unit sets the individual response timing for the terminal device that individually responds to the receiving unit. When the individual response timing is changed for each terminal device and the state of the terminal device changes, the terminal device that changes this state responds to the receiving unit at the timing of its own response. Terminal device special response timing is provided.

Then, when there is a response to the receiving section at the special response timing of the specific terminal, the specific terminal which has changed the state is immediately detected by the system polling for the specific terminal and the point polling for the specific terminal which will be described later. It is like this.

“System polling for specific terminal equipment”
Divides the specific terminal devices into a plurality of groups, sets the group response timing for the specific terminal devices in which one or more specific terminal devices in the same group simultaneously respond to the receiving unit, and sets the group response timing for each of the groups. When the group response timing is changed for each group and the state of the specific terminal device changes, at the time of the group response timing for the specific terminal device of the group to which the specific terminal device whose state has changed, the specific terminal device whose state has changed is the receiving unit. Polling in response to.

[Point polling for specific terminal equipment]
Sets the individual response timing for a specific terminal device in which each specific terminal device in the group to which the specific terminal device responds to the receiving unit in the system polling for the specific terminal device individually responds to the receiving unit. This is polling in which the individual response timing is changed for each specific terminal device, and when the state of the specific terminal device changes, the specific terminal device whose state has changed responds to the receiving unit at the timing of its own response.

"Selecting" is to call a specific terminal device responding to the receiving unit in system polling for specific terminal device, point polling for specific terminal device, etc.
This is polling in which the receiving unit collects predetermined information from the specific terminal device or the receiving unit specifies and controls the terminal device.

When the receiver RE sequentially calls a plurality of terminal devices to request transmission of specific information and receives the specific information from the terminal device, it is determined that the terminal device has not failed. At the same time, it is determined that there is no disconnection between the receiver and the terminal device. When the type information is used as the specific information, the type information received by the receiver RE from the terminal device and the receiver R
The receiver RE collates the type information of the terminal device registered in E, and if the two types of information do not match, it is determined that the type of the terminal device has been changed.

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

First, in FIG. 1 and FIG. 3, the operation proceeds from the upper left to the upper right, and the operation proceeds from the right end to the left end of the next lower stage. In this way, the processing proceeds sequentially.

In FIG. 1 and FIG. 3, the receiver R is shown on the horizontal line.
The operation of E and the operation of the transmitter P or a terminal device other than the transmitter P are shown below the horizontal line. In addition, in FIGS. 1 and 3, the broken line frame indicates the response timing of the signal indicating that the state change has occurred, and when there is no description in the broken line frame, the signal indicating the state change is transmitted by the transmitter P. Alternatively, it indicates that a terminal device other than the transmitter P did not output (that is, did not respond to polling), and if a pulse waveform is described in the frame of the broken line, the frame of the broken line is displayed. It shows that it responded to the receiver RE at the timing, and the signal returned by the transmitter P or the like to the receiver RE is shown in the frame of the solid line below the horizontal line.

FIG. 1 is a time chart when there is no transmitter P or the like whose state has changed (that is, a normal time chart), and FIG. 3 shows a transmitter P or the like whose state has changed. It is a time chart when it exists.

First, in P1 of FIG. 1, normal system polling is performed. That is, all terminal devices are grouped into some groups (grouped into four groups in FIG. 1), and terminal device group response timings T ₀ , T ₁ , T ₂ , T ₃ are set for each group, Also, the transmitters are grouped into one group, the transmitter special response timing T _P is set in this group, and the receiver RE is a signal SPAD / CM indicating a status information return command in normal system polling.
2, the terminal device whose state has changed (operating terminal device) responds to each of the response timings T ₀ , T ₁ , T ₂ and T _{3 of the} group to which the terminal device belongs (response timing
T ₀ , T ₁ , T ₂ and T ₃ are preset to be different from each other), responding by sending a pulse to the receiver RE indicating that the state has changed, and the transmitter that has changed state (the active transmitter). The transmitter special response timing T _P (the transmitter special response timing T _P is the response timing T ₀ , T ₁ , T ₂ , T ₃
, Which is preset) to respond by sending a pulse to the receiver RE indicating a change of state.

If there is a response from the transmitter at the transmitter special response timing T _P , the transmitter system polling is executed before the normal point polling. Therefore, in the above embodiment, normal point polling,
Even if the selecting operation takes a long time, the system polling for the transmitter is always executed prior to the point polling. Therefore, when the transmitter P operated by human judgment operates, the transmitter P is operated. The more the receiver RE can quickly grasp the fire information from P and the larger the fire alarm equipment, the greater the effect.

In the normal system polling described above, if the state of the terminal equipment (including the transmitter P) has not changed (not operating), then, in P2 of FIG. Ting. That is, in order to determine the disconnection (that is, the presence or absence of connection) of the terminal device having the address 0, the code SAD (n) .CM indicating the type information return command is sent.
3 (n is a number indicating an address, which is 0 in this case) is transmitted, and in response to this, a code SAD indicating the self-address and the type of the fire detector from the terminal device having the address 0.
(N). If the ID (ID is a type and n is 0) is returned to the receiver RE, the receiver RE can confirm that no disconnection has occurred with the terminal device having the address 0.

After that, in P3 of FIG. 1, the same normal system polling as in P1 is performed again, and in P4 of FIG. 1, similar to the disconnection discrimination selecting in P2, but the next address. The disconnection discrimination selecting is performed for the terminal device No. 1, the normal system polling same as the normal system polling in P1 is performed in P5 of FIG. 1, and these operations are repeated. That is, normal system polling and disconnection discrimination selection are repeated, and every time these cycles are completed, the disconnection discrimination is performed for the terminal device whose address is incremented by 1 in the disconnection discrimination selection.

FIG. 3 shows the transmitter P and the transmitter P whose states have changed in the normal system polling in the above embodiment.
6 is a time chart showing an operation when the state of a terminal device other than is changed.

In the normal system polling P3a corresponding to P3 of FIG. 1, there is a response at the terminal device group response timing T ₁ and the transmitter special response timing T _P , and the response at the terminal device group response timing T ₁ is The terminal device belonging to the group G1 corresponding to the response timing T ₁ has a state change, and the response at the transmitter special response timing T _P shows that one of the transmitters P has a state change. In this case, the transmitter system polling is executed prior to the normal point polling (P10 in FIG. 3), and the pulse is returned from the transmitter P at the transmitter group response timing T _P1. It is shown that any one of the transmitters P belonging to the second group of 1 has responded (the state of the transmitter P has changed), and at P11 of FIG. To be executed.

That is, the code GAD (g) indicating the transmitter point poll for the receiver RE to determine which one of the transmitters P belonging to the group responded.
CM1 is sent to the terminal device (g is a number indicating a group, which is 1 in this case), and the transmitter P is sent at the fourth individual response timing t _P3 for the transmitter belonging to the group in response to this polling. Since the pulse is sent back from the transmitter, it means that the transmitter P with the address 7 (the eighth transmitter P), which is the fourth of the four transmitters P belonging to the group, responded, and at P12. The receiver RE selects the transmitter P having the address 7 and requests data.

That is, the receiver RE has a code SAD indicating a status information return command to the terminal device at the address 7.
(N) CM0 (n is a number indicating an address, and in this case is 7) is transmitted. In contrast, address 7
Of the transmitter P is a signal SAD (n) · DA (DA is the data to be sent, which indicates its own address and the data to be sent, and in this case, the fire signal is set as the data,
n is 7) to the receiver RE.

In P13 of FIG. 3, the receiver RE, based on the received data DA, issues a code SAD (n) .CM4 indicating a fire confirmation command to the eighth transmitter P.
(N is a number indicating an address, which is 7 in this case)
Is sent. As a result, the eighth transmitter P turns on the response light, and the fact that the eighth transmitter P has issued a warning can be reliably displayed.

Here, the "fire confirmation command" is a "command for a terminal device whose operation is confirmed among the terminal devices to stop the terminal device from responding to the receiver RE". Based on the status information collected by the receiver RE from the terminal device by selecting, the receiver RE determines that the terminal device has detected a fire and performs alarm processing such as display of a fire area (that is, the terminal). When a fire is confirmed for a device), the fire confirmation status for the terminal device is
Do not release until fire recovery operation is performed. If the terminal device continues to respond to system polling or point polling after the fire is confirmed, the receiver RE will perform meaningless processing on the terminal device even if the fire confirmation is maintained. Further, this meaningless processing delays the polling and selecting operations for other terminal devices whose operations are not fixed.

Therefore, the receiver RE is connected to the terminal device for which the fire has been confirmed (that is, the terminal device for which the operation has been confirmed).
Sends a fire confirmation command by selecting, and thereafter stops the terminal device from responding to system polling and point polling. In the above explanation, the case where the fire is confirmed has been explained, but the fire detector has failed (for example, the light emitting element stops emitting light).
In the event of a fire, or even when the operation is confirmed by, for example, disconnecting the secondary side electric circuit in the repeater, the response to system polling and point polling may be stopped by the fire confirmation command. .

In the case of the transmitter P, when the push button is pressed, the receiver RE displays the fire area or address,
Since the alarm is issued, the operation of the transmitter P is fixed.

Therefore, the eighth transmitter P, which has received the fire confirmation command SAD (7) CM4 from the receiver RE,
It stops responding to subsequent system polls and point polls. In addition, when the processing for the fire is completed and the equipment is restored, the fire restoration command SP in P14
When the receiver RE sends the AD / CM 6, the transmitter P, which has received the fire confirmation command as described above, is restored by the fire restoration signal.

After the above-mentioned transmitter system polling, transmitter point polling, selecting, etc. are completed, normal system polling is executed again, and if necessary, normal point polling, selecting, etc. are carried out.

That is, the normal system polling is executed again at P20 of FIG. 3, the state of the terminal equipment such as the fire detector S belonging to the group G1 corresponding to the terminal response group response timing T ₁ changes, and the state of FIG. In P21, normal point polling is performed. That is,
In P20, the receiver RE normally codes SPAD / CM2 indicating a status information return command by system polling.
And a pulse is returned at the second terminal device group response timing T ₁ , and in P21, a status information return command GAD (g) · C by normal point polling.
M2 is sent to the terminal device of the group G2 (g is a number indicating the group, which is 2 in this case), and the pulse is returned from the terminal device at the third terminal device individual response timing t ₂ . Therefore, of the four terminal devices belonging to the group G1, the third terminal device (the eleventh terminal device)
Means that the receiver RE has changed to the 11th terminal device (address 10).
Terminal device) to request data. That is, the receiver RE receives the address signal of the terminal device and the status information return command SAD (n).
CM0 (n is a number indicating an address, in this case, 1
Is 0). On the other hand, address 10
The terminal device has a code SAD (n) · DA (in this case, n is 10 and DA
Is data to be sent) to the receiver RE.

In P22 of FIG. 3, the receiver RE performs the necessary operation for the signal level of the received data DA, based on the received data DA. Explaining this signal level, normally, in the case of a smoke detector, for example, in the case of a smoke detector, there are 1 to 3 levels, and specifically, a smoke concentration of 5% / m in terms of extinction ratio is obtained. 1 type, 10% / m is 2
Seed, 15% / m is set to be at 3 levels. Then, in the storage means described later in the receiver RE, the fire determination level for fire alarm is stored for each address,
Interlocking information for each level (information such as operation of controlled terminal equipment)
Is stored and the operation according to the level is performed. Receiver R
E determines whether or not the data from the terminal device with the address 10 is a signal for fire alarm (for example, a signal of level 2), and if the data received from the terminal device is a signal of level 1, for example, In P23 of 3, the address 10
A level stop command SAD (n) .CM5 (n is 10 in this case) indicating that the signal of that level is not necessary is sent to the terminal device.

Here, the "level stop command" is to "discriminate the level signal of smoke or the like received from the fire detector in selecting, and if the received level signal is not the level signal of the desired fire discrimination level. , The command to stop the fire detector from sending the response signal with respect to the received level signal. Therefore, the fire detector S, which has received the level stop command, does not subsequently respond to the level whose response has been stopped.

1 kind of fire equivalent level (level for distinguishing fire with 5% smoke density), 2 kinds of fire equivalent level (1
It has multiple judgment levels, such as a level for distinguishing fires with 0% smoke concentration), a level equivalent to 3 types of fires (a level for distinguishing fires with 15% smoke concentration), and a distinction of fires for each distinction level. However, it is effective to use the above level stop command for a multi-signal type fire detector that sends a corresponding level signal. That is, the receiver RE discriminates the level of the signal received from the multi-signal type fire detector, and if the fire equivalent level of the received level signal is not the level signal corresponding to the desired fire equivalent level, it is received. Regarding the level signal, after that, a level stop command for stopping the transmission of the response signal to the multi-signal type fire detector is sent, and the multi-signal type fire detector that has received the level stop command causes the system polling at the level equivalent to the fire, Receiver R by point polling
Do not respond to E. Therefore, even if the multi-signal fire detector is repeatedly turned on and off at a smoke concentration lower than the level at which the receiver RE determines that it is a fire, a useless response signal due to this is not sent to the receiver RE. It is possible to prevent processing delay in the receiver RE.

In the above embodiment, in the case of system polling, point polling and selecting a plurality of terminal devices, a fire confirmation command is sent to the terminal device whose operation has been determined, and a response to the receiver RE in system polling and point polling is sent. I'm trying to stop
As the "terminal device whose operation has been confirmed", in addition to the transmitter P that has sent the fire signal to the receiver RE, the accumulation-type fire detector that has sent the fire signal to the receiver RE and the accumulation by the receiver RE have been completed. There is a non-accumulation type fire detector.

As described above, when performing system polling, point polling, and selecting a plurality of terminal devices, a fire confirmation command is sent to the terminal device whose operation has been confirmed, and the response to the receiving unit is stopped, so the operation of the terminal device is stopped. Even if the detection level of smoke or the like is repeatedly increased or decreased near the level equivalent to a fire after is determined, the response to the receiver is not performed and the processing of the receiver is not delayed. When the equipment is restored, the receiving unit sends a fire recovery command signal to the terminal device, and the terminal device that has received the fire confirmation command is recovered by this fire recovery command. In addition, the multi-signal fire detector that received the level stop command is also restored by the fire restoration command.

If the status information does not match, it means that the status of the transmitter P has changed. At this time, the RAM 34 is referred to (S478a, S479a), and if the response stop flag is not stored (S471b), the RAM 35 is used. Since it is in a state in which the status information of the transmitter P can be sent to the receiver RE, the in-group number m and the transmitter number p of the transmitter P are stored in the RAM3.
5 is read (S472b), and the slot number s is set to "0" (S473b).

When the slot number s and the in-group number m match (S474b), a response pulse is sent to the receiver RE (S475b) to respond to the receiver RE.
If the slot number s and the in-group number m do not match (S474b), the slot number s is incremented by 1 (S476b, S477b) when the transmission timing for the slot number s is up (S476b, S477b). Collate with the number m (S474)
b). The slot number s and the group number m match,
A response pulse is sent to the receiver RE (S474b, S47
5b), if the slot number s and the transmitter number p do not match (S478b), the slot number s is incremented by 1 when the transmission timing for the slot number s is up (S471c, S472).
c), the slot number s and the transmitter number p are collated (S4
78b), when they match, a response pulse is sent to the receiver RE (S478b, S479b).

On the other hand, the command received from the receiver RE is
If it is not CM2 (S476a) and other instructions,
Processing according to the command is performed (S473c).

FIG. 27 is a flowchart showing a specific example of the selecting process (S490) executed by the transmitter P in the above embodiment.

The command received from the receiver RE is the selecting command SA which specifies the address n of the transmitter P.
If it is D (n) (S480) and the status information return command CM0 by selecting (S491), the address n of the terminal device is read from the RAM 35, the data DA indicating the current status information is read from the RAM 32, and the signal transmission / reception is performed. A command SAD (n) .DA indicating the state change of the transmitter P is sent from the section TRX3 (S492), and the RAM is sent.
The sent data DA is stored in 33 (S49).
3). The command received from the receiver RE is not the status information return command CM0 but the command CM3 requesting the type information.
(That is, disconnection discrimination selecting) (S49
1, S494), the address n of the terminal device is read from the RAM 35, and the type information ID of the transmitter P is read in the ROM 32.
Command SAD (n)
The ID is transmitted from the signal transmitting / receiving unit TRX3 (S49
5).

On the other hand, if the command received from the receiver RE is the fire confirmation command CM4 (S496), an ON signal is sent to the response light LED to light the LED (S497), and based on the subsequent state information. The fire confirmation flag for stopping the response regarding the system polling and the point polling is stored in the RAM 34 (S498).
The command received from the receiver RE is the remote test command CM8.
If so (S491a), the test flag is stored in the RAM 33 (S492a), the test process is performed (S493a),
If it is any other instruction, processing according to the instruction is performed (S494a).
