Embodiments and Examples of the Invention
FIG. 1 is a circuit diagram showing a fire receiver test apparatus RT1 according to one embodiment of the present invention.
[0009]
The fire receiver test device RT1 includes an MPU 1, a switch group including a plurality of switches SW1 to SW6, an LED group including a plurality of status lights LED1 to LED6, a display unit DP, and an operation unit. It has an OP, a sensor power supply circuit 21, receiving circuits R1 to Rn, a smoke prevention equipment power supply circuit 22, and start-up circuits DR1 to DRn.
[0010]
The MPU 1 is a one-chip microcomputer having a CPU (central processing unit) 10, a work RAM 11, a fire test RAM 12, a program ROM 13, and a switch I / F (not shown) for the switches SW1 to SW6. Note that a nonvolatile memory such as an EEPROM may be used instead of the backup RAM 12.
[0011]
As the switches SW1 to SW6, a fire test switch SW1, a fire hydrant cutoff switch SW2, an emergency broadcast interlocking switch SW3, a fire signal shutoff switch SW4, a smoke prevention smoke interlocking switch SW5, and a smoke prevention smoke notification switch SW6 is provided.
[0012]
As the status lights LED1 to LED6, a fire test status light LED1, a fire hydrant shutoff status light LED2, an emergency broadcast interlocking shutoff status light LED3, a fire signal shutoff status light LED4, a smoke emission interlocking shutoff status light LED5, A flue gas transfer cutoff state light LED6 is provided. A heat detector or a smoke detector S is connected to the detector lines L1 to Ln, and a smoke prevention device such as a shutter is connected to the smoke prevention activation lines DR1 to DRn.
[0013]
The work RAM 11 is a first storage unit that stores the state of the switches SW1 to SW6, and the fire test RAM 12 is a second storage unit that stores the state of the switches SW1 to SW6 during the fire test. Non-volatile memory such as a possible RAM or EEPROM. The ROM 13 is a memory for storing the program of the flowchart shown in FIG.
[0014]
Next, smoke interception interception interception will be described.
[0015]
First, in the above embodiment, when the detector S connected to the line L1 detects a fire condition, a start signal is output to the smoke elimination device T connected to the line D1 corresponding to the line L1. Assume that an interlocking relationship has been established.
[0016]
Here, when the smoke prevention switch SW5 is pressed, the smoke prevention state light LED5 is turned on, and even if a fire signal is received from the sensor S via the line L1, a line that is interlocked with the line L1 is received. No activation signal is output from the activation circuit DR1 to D1. As a result, the power supply to the smoke control device is cut off. As described above, it is possible to prevent the start signal for activating smoke evacuating from being output to the line D1 which is interlocked with the line L1 (that is, not to send an external sending signal to the outside of the fire receiver). It is smoke exhaust interlocking.
[0017]
Next, the operation of the test apparatus RT1 will be described.
[0018]
FIG. 2 is a flowchart illustrating the operation of the test apparatus RT1.
[0019]
First, the interruption state stored in the RAM 11 is read (S1). Thereafter, when it is detected that the state of the fire test switch SW1 has changed (S2), if the change is a change that turns on the fire test switch SW1 (S3), the cutoff switches SW2 to SW6 have priority over the cutoff state. Among them, the cutoff state of the cutoff switches other than the cutoff switch that is currently set to the cutoff state is set to the content set in the RAM 12 (S4). That is, when the cutoff switch is set to the cutoff state in either the RAM 11 or 12, the cutoff switch is set to the cutoff state. Then, a process of starting a fire test is executed (S5). After that, unless the fire test switch SW1 is turned off, the fire test state is continued.
[0020]
When the fire test switch SW1 is turned off during the fire test (S3), the state of each of the cutoff switches SW2 to SW6 is read from the RAM 11, and the switch SW2 is read in accordance with the read state of the switches SW2 to SW6. The start signal to the controlled device corresponding to SW6 is shut off (S11). That is, when the fire test switch SW1 is turned off during the fire test (S3), when the state of each of the cutoff switches SW2 to SW6 is read from the RAM 11, the fire hydrant cutoff switch SW2, the emergency broadcast interlocking cutoff switch SW3, the fire If it is found that the signal cutoff switch SW4, the smoke prevention interlocking cutoff switch SW5, and the smoke prevention notification transfer cutoff switch SW6 are set to the cutoff state, respectively, the hydrant cutoff, the emergency broadcast interlocking cutoff, the fire signal cutoff, the fire prevention Smoke emission interlocking and smoke prevention signaling are cut off. Then, a fire test termination process is performed (S12).
[0021]
On the other hand, after reading the cutoff state stored in the RAM 11 (S1), the state of the fire test switch SW1 does not change (S2), and there is a cutoff switch whose state has changed among the cutoff switches SW2 to SW6 ( S21) If the interrupted switch that has changed state has changed from the off state to the on state (S31), the state of the interrupter switch that has changed to the on state, that is, the change of the interrupter switch to the on state, is determined by the RAM 11. (S32), and turns on the switch light of the cut-off switch that has been turned on, sets the cut-off switch to the cut-off state (S33), and returns to step S2.
[0022]
In addition, among the cutoff switches SW2 to SW6, there is a cutoff switch whose state has changed (S21), and if the cutoff switch whose state has changed has changed from an on state to an off state (S31), the state changes to the off state. The state of the cut-off switch, that is, the change of the cut-off switch to the off state is stored in the RAM 11 (S34), the switch light of the cut-off switch changed to the off state is turned off (S35), and the fire test is being performed. If (S36), the cutoff state of the cutoff switch is set to the content set in the RAM 12 (S37), and the process returns to step S2. If the fire test is not being performed, the cutoff is released according to the state of the cutoff switch (S38), and the process returns to step S2.
[0023]
That is, when any of the cutoff switches SW2 to SW6 is turned on from off, the change to on is stored in the RAM 11, the corresponding switch light is turned on, and one of the cutoff switches SW2 to SW6 is turned off from on. If it is, the change to off is stored in the RAM 11, and the corresponding switch light is turned off.
[0024]
If the smoke prevention smoke interlocking switch SW5 is pressed again during the continuation of the fire test, the smoke prevention smoke interlocking switch LED5 is turned off and the cutoff state of the smoke prevention smoke interlocking switch SW5 is set to the cutoff priority. The smoke exhaust interlocking switch SW5 is maintained in the shut off state. When the fire test is completed, the smoke-exhaust smoke interlocking cutoff switch SW5 enters the cutoff release state.
[0025]
Similarly, in the normal monitoring state, when the smoke-exhaust interlock switch SW5 is pressed again, the smoke-exhaust interlock switch LED5 is turned off, and the smoke-exhaust interlock switch SW5 is in the shut-off release state.
[0026]
The setting of the shut-off state of each shut-off switch in the RAM 12 at the time of the fire test is performed using a nonvolatile memory such as an EEPROM in which the settings are stored in advance. When a RAM that can be backed up is used, a preset shut-off state setting mode is set so that even if various switches in the fire receiver are operated, the shut-off state cannot be easily set from the fire receiver panel. By operating a hidden switch, a switch for selecting a cutoff switch to be set, a switch for designating cutoff / cutoff, and the like, the cutoff state of the cutoff switch can be set, and the contents thereof are stored in the RAM 12. I have. This setting has no effect on the above-described normal linkage.
[0027]
In the above embodiment, when the fire test switch SW1 is pressed to turn on the fire test status light and the fire test state is entered, the smoke prevention and smoke interlocking operation stored in the RAM 12 is effective only at the time of the fire test. In order to distinguish from the interruption by the RAM 11 in the above, the smoke prevention smoke cutoff state lamp is not turned on, but is in the smoke prevention state in the internal state.
[0028]
Therefore, when the line L1 is subjected to a fire test, the line L1 is in the same state as at the time of a fire. Therefore, an activation signal should be output to the line D1 which is interlocked with the line L1. Since D1 is in the cutoff state, no activation signal is output to the line D1. Further, even if the smoke prevention switch SW5 is operated during the fire test, the state in which the lines D1 to Dn relating to the smoke prevention device are blocked is not released. However, since the shutoff / release state operated by the smokeproof smoke cutoff switch SW5 and the state of the smokeproof smoke interlocking cut-off state light are reflected at the end of the fire test, the smokeproof smoke cutoff interlock switch SW5 is set during the fire test. When used and set to the shut-off state, the smoke-exhaust interlocking shut-off state is continued even after the fire test is completed.
[0029]
FIG. 3 is an operation explanatory diagram in another embodiment of the present invention.
[0030]
At the time of initial setting (at the time of start) a, the contents stored in the RAM 11 are the states of the cutoff switches SW2 to SW6. When the state of the cutoff switches SW2 to SW6 is changed immediately before the fire test b, the changed contents are stored in the RAM 11. In the example shown in FIG. 3, the emergency broadcast interlocking switch SW3 and the smoke-prevention smoke notification switch SW6 are changed to "blocking".
[0031]
When the fire test switch SW1 is turned on (at the time of the fire test c), immediately before the fire test b, the line for the terminal device corresponding to the cut-off switch set to the cut-off state keeps the cut-off state of the output signal of the start signal. The line for the terminal device corresponding to the other cutoff switch is in the same state as the state stored in the RAM 12. Immediately before the fire test, the cut-off switch light of the cut-off switch corresponding to the terminal device line set to the cut-off state is turned on, and the cut-off switch corresponding to the terminal device line cut off by the contents of the RAM 12 at the time of the fire test. The cutoff switch light turns off.
[0032]
Further, when the state of the cutoff switch is changed during the fire test d, the change is stored in the RAM 11. In the example shown in FIG. 3, the fire signal cutoff switch SW4 is changed to "cutoff", and the smoke prevention smoke notification cutoff switch SW6 is changed to "cutoff". If the cutoff switch that has been released is changed to cutoff during the fire test, the cutoff state is set and the cutoff switch is turned on. In addition, when the shut-off switch that was shut off during the fire test is released, the shut-off switch that was shut off during the fire test remains in the shut-off state, the shut-off switch goes out, and the shut-off switch that was released during the fire test turns off the shut-off switch. The state is released and the cutoff switch goes out.
[0033]
At the end of the fire test e, the contents stored in the RAM 11 are in the state of each cutoff switch.
[0034]
According to the above-described embodiment, in the fire test, a test is performed in which a line linking a controlled device such as a smoke control device is set to a fire state. The device will not be started. Further, if the shut-off switch is operated during the test, the operation is reflected at the end of the test, so that useless operation can be eliminated.
[0035]
Note that the above embodiment is a test apparatus for a fire receiver that causes a fire receiver to shift to a test state by operating a fire test switch, and the cutoff switches SW2 to SW6 send out to the outside of the fire receiver. It is an example of a cutoff switch that cuts off output of an external transmission signal.
[0036]
The activation signals output from the activation circuits DR1 to DRn are examples of external transmission signals transmitted to the outside of the fire receiver. That is, the external transmission signals include a smoke control signal, a fire signal, and a smoke control. It is at least one of a transfer signal and an emergency broadcast interlocking signal. The RAM 11 is an example of a first storage unit that stores the state of the cutoff switch, and the RAM 12 is a second storage unit that stores the state of the cutoff switch in a fire test.
[0037]
Further, the MPU 1 operates the fire test switch to read the state of the cutoff switch from the second storage means, and stores the state of the cutoff switch stored in the first storage means or the second storage means. If any one of the states is a cutoff state, the output of the external transmission signal of the cutoff switch is cut off. On the other hand, when the operation of the fire test switch is canceled, the state of the cutoff switch is stored in the first storage. This is another example of the external transmission signal blocking unit that reads out from the unit and executes blocking or release of the output of the external transmission signal in accordance with the state of the blocking switch that is read.
[0038]
Next, the operation of the test apparatus RT1 will be described based on the operation explanatory diagram of each cutoff switch shown in FIG.
[0039]
First, in the flowchart shown in FIG. 2, the interruption state stored in the RAM 11 is read (S1). At this time, the state of each of the cutoff switches SW2 to SW6, each of the cutoff state lights, and the state of the RAM 11 are shown in FIG.
[0040]
The state of each of the cutoff switches SW2 to SW6 read from the RAM 11 is such that the hydrant cutoff switch SW2 is in the cutoff state and the other cutoff switches SW3 to SW6 are in the cutoff release state. All of the shutoff status lights of the shutoff switch are off.
[0041]
After reading the cutoff state stored in the RAM 11 (S1), the state of the fire test switch SW1 does not change (S2), and there is a cutoff switch whose state has changed among the cutoff switches SW2 to SW6 (S21). If the cut-off switch that has changed state has changed from the off state to the on state (S31), the state of the cut-off switch that has changed to the on state, that is, the change of the cut-off switch to the on state, is stored in the RAM 11. (S32), the cut-off state lamp of the cut-off switch that has been turned on is turned on, the cut-off switch is turned off (S33), and the process returns to step S2.
[0042]
The state of each of the cutoff switches SW2 to SW6 and each of the cutoff state lights and the state of the RAM 11 at this time are shown in FIG. In FIG. 3 (b), the emergency broadcast interlocking switch SW3 and the smoke prevention / smoke prevention alarm switch SW6 are changed from the shutdown release state to the shutdown state. The cutoff state of SW6 is stored in the RAM 11, and the cutoff state lights of the emergency broadcast interlocking switch SW3 and the smoke-prevention / smoke-prevention notification switch SW6 are turned on.
[0043]
Further, the state of the fire test switch SW1 does not change (S2), and among the shutoff switches SW2 to SW6, there is a shutoff switch whose state has changed (S21), and the shutoff switch whose state has changed changes from the on state to the off state. When it changes (S31), the state of the cut-off switch changed to the ON state, that is, the change of the cut-off switch to the OFF state is stored in the RAM 11 (S34), and the cut-off state light of the cut-off switch changed to the OFF state. Is turned off (S35). Further, in this case, since the fire test is not being performed (S36), the cutoff switch is set to the cutoff release state (S38), and the process returns to step S2.
[0044]
The state of each of the cutoff switches SW2 to SW6 and each of the cutoff state lights and the state of the RAM 11 at this time are shown in FIG. In FIG. 3B, since the hydrant cutoff switch SW2 is changed from the cutoff state to the cutoff release state, the cutoff release state of the hydrant cutoff switch SW2 is stored in the RAM 11, and the cutoff light of the hydrant cutoff switch SW2 is turned on. Turns off.
[0045]
When the fire test switch SW1 is turned on after this state, it is detected that the state of the fire test switch SW1 has changed (S2), and the change is a change for turning on the fire test switch SW1 (S3). Since the interruption state is prioritized, the interruption state of the interruption switches other than the interruption switch currently set to the interruption state among the interruption switches SW2 to SW6 is set to the contents set in the RAM 12 (S4). . That is, when the cutoff switch is set to the cutoff state in either the RAM 11 or the RAM 12, the cutoff switch is set to the cutoff state. Then, a process of starting a fire test is executed (S5), and thereafter, the fire test is continued unless the fire test switch SW1 is turned off.
[0046]
The state of each of the cutoff switches SW2 to SW6 and each of the cutoff state lights at this time is shown in FIG. In FIG. 3 (c), the emergency broadcast interlocking switch SW3 and the smoke-prevention / smoke prevention alarm switch SW6 which are set to the shut-off state in the RAM 11 of FIG. 3 (b) are in the shut-off state. The cutoff status light of the smoke exhaustion cutoff switch SW6 remains lit. Further, although the smoke-prevention smoke interlocking cut-off switch SW5 and the smoke-prevention smoke transfer notification cut-off switch SW6 which are set to the cut-off state in the RAM 12 of FIG. Is shut off according to the contents stored in the switch, the smoke prevention / exhaust smoke interlocking switch SW5 is newly turned off. Note that the cut-off state light of the smoke prevention and smoke interlocking cut-off switch SW5 is cut off by the RAM 12, so that the cut-off state light remains off.
[0047]
Next, a case where the state of the cutoff switch is changed during the fire test will be described.
[0048]
During the fire test, the state of the fire test switch SW1 does not change (S2), and among the cutoff switches SW2 to SW6, there is a cutoff switch whose state has changed (S21), and the cutoff switch whose state has changed is turned on from the off state. If the state has changed (S31), the state of the cutoff switch changed to the ON state, that is, the change of the cutoff switch to the ON state is stored in the RAM 11 (S32), and the cutoff changed to the ON state. The cut-off state lamp of the switch is turned on, the cut-off switch is turned off, and the process returns to step S2.
[0049]
The state of each of the cutoff switches SW2 to SW6 and each of the cutoff state lights and the state of the RAM 11 at this time are shown in FIG. In FIG. 3D, since the fire signal cutoff switch SW4 is changed from the cutoff release state to the cutoff state, the cutoff state of the fire signal interlocking switch SW4 is stored in the RAM 11 and the fire signal cutoff switch SW4 is turned off. The shutoff status light has changed to lit.
[0050]
In addition, during the fire test, the state of the fire test switch SW1 does not change (S2), and among the cutoff switches SW2 to SW6, there is a cutoff switch whose state has changed (S21), and the cutoff switch whose state has changed is turned off. If the state has changed from ON to ON (S31), the state of the cutoff switch changed to the ON state, that is, the change of the cutoff switch to the ON state, is stored in the RAM 11 (S32), and the state changed to the ON state. The cut-off state light of the cut-off switch is turned on, the cut-off switch is turned off, and the process returns to step S2.
[0051]
The state of each of the cutoff switches SW2 to SW6 and each of the cutoff state lights and the state of the RAM 11 at this time are shown in FIG. In FIG. 3D, since the smoke-prevention / smoke transfer / interruption switch SW6 is changed from the cut-off state to the cut-off release state, the cut-off state of the smoke-prevention / smoke-prevention transfer switch SW6 is stored in the RAM 11 and the smoke-prevention / smoke transfer switch SW6 is stored. The cutoff status light of the smoke transfer cutoff switch SW6 has changed to lighting. However, since the cut-off state is set in the RAM 12, even if the cut-off switch SW6 is released, the cut-off state remains in the cut-off state according to the settings in the RAM 12. Note that the display of the cut-off state lamp does not change because the cut-off state is determined by the RAM 12.
[0052]
Furthermore, during the fire test, the state of the fire test switch SW1 does not change (S2), and among the cutoff switches SW2 to SW6, there is a cutoff switch whose state has changed (S21). If the state changes from OFF to OFF (S31), the state of the shut-off switch changed to the OFF state, that is, the change of the cut-off switch to OFF is stored in the RAM 11 (S34), and the state changes to the OFF state. The shut-off status light of the shut-off switch is turned off (S35). Further, in this case, since a fire test is being performed (S36), the cutoff state of the cutoff switch is maintained (S37), and the process returns to step S2.
[0053]
Further, when the fire test switch SW1 is turned off during the fire test (S3), the cutoff state of each of the cutoff switches SW2 to SW6 is read from the RAM 11, and according to the read state of the switches SW2 to SW6. Then, the activation signal to the controlled device corresponding to the switches SW2 to SW6 is cut off (S11). That is, when the fire test switch SW1 is turned off during the fire test (S3), when the status of the various shutoff switches SW2 to SW6 is read from the RAM 11, the fire hydrant shutoff switch SW2, the emergency broadcast interlocking shutoff switch SW3, the fire If it is found that the signal cutoff switch SW4, the smoke prevention interlocking cutoff switch SW5, and the smoke prevention notification transfer cutoff switch SW6 are set to the cutoff state, respectively, the hydrant cutoff, the emergency broadcast interlocking cutoff, the fire signal cutoff, the fire prevention Smoke emission interlocking and smoke prevention signaling are cut off. Then, a fire test termination process is performed (S12).
[0054]
The state of each of the cutoff switches SW2 to SW6 and each of the cutoff state lights and the state of the RAM 11 at this time are shown in FIG. In FIG. 3E, according to the contents stored in the RAM 11, the emergency broadcast interlock switch SW3 and the fire signal cutoff switch SW4 are turned off, and the other cutoff switches are turned off.
[0055]
