In addition, if the timer means collects the test result information and processes them within a predetermined time, and if there is an abnormality, it automatically displays and warns, so that the operator must wait until the end of the test. There is no.

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

FIG. 1 shows the present invention by taking a polling-type disaster prevention facility as an example. In the figure, a receiver RE is connected to a plurality of terminal devices SE, that is, SE1 to SEn. For convenience of explanation, all the terminal devices SE1 to SEn shown here are receivers RE that use the detected analog quantity of the fire phenomenon as a digital signal.
Although it is a type of fire detector that is sent to the fire, it is actually a terminal device of various types required for disaster prevention, for example, an on / off type fire that outputs a fire signal when a fire phenomenon exceeding a predetermined value is detected. Those skilled in the art will appreciate that sensors or repeaters or the like can be hybridized.

In the receiver RE, the CPU is a microcomputer, ROM

ROM2 stores the reference value for discrimination of each terminal device used when executing the program of ROM1, that is, the fire discrimination value, the test start allowable value, the test result discrimination value, etc.,
And in the ROM3, the addresses and types of the connected fire detectors SE1 to SEn, such as a heat sensor or a smoke sensor,
A terminal map indicating whether it is a gas sensor or the like is stored. TM
1 is a test timer used during the test, DP is a display area such as a fire area display window or a display such as a CRT display and various lamps, OP is a terminal test together with various switches such as an acoustic stop switch and a recovery switch The operation unit is provided with a switch SW, a terminal selection switch, and the like. RAM1 and
RAM2 is a random access memory, RAM1 is used for work such as polling and various kinds of discrimination, and RAM2 is used for storing status information received from each terminal device. TR is a transmission / reception unit having a serial / parallel conversion circuit, a transmission circuit and a reception circuit.

The analog-type fire detectors SE1 to SEn have the same internal structure, and therefore the details of the structure are shown only for SE1.

In the fire detector SE1, the CPU is a microcomputer,
FD is a thermal type or smoke type fire detection unit, ADC is an analog-digital converter that converts the analog quantity signal output from the fire detection unit FD into a digital signal. , Analog / digital converter AD
C and an abnormal phenomenon detection unit. TC is a test circuit which is a part of the test means, and when the fire detection unit FD is a thermal type having a thermistor, a heater and the like for heating the thermistor to a predetermined temperature are provided. ROM21
Is a read-only memory that stores the program,
RAM21 and RAM22 are random access memories,
The RAM 21 is used for work, and the RAM 22 is used at the start of the test to store the detection output of the fire detection unit FD which is AD-converted immediately before the start of the test. TM21 is a timer that is activated at the start and end of the test.The operation time depends on the heater at the start of the test when the fire detection unit FD is a thermistor thermal type and the test circuit TC has a heating heater. It is set to be slightly longer than the time required for the output of the heated thermistor to stabilize and the time required for the output of the thermistor to stabilize after heating of the thermistor is stopped at the end of the test. TR is a transmission / reception unit and has the same configuration as that of the receiver RE.

Next, the operation of the present invention will be described with reference to the flowcharts shown in FIGS.

First, the operation during normal fire monitoring will be described with reference to FIG.

The CPU of the receiver RE performs an operation of sequentially polling the terminal devices SE1 to SEn. The decisions in blocks 103-107 that follow after the nth fire detector is set to be polled (block 102) are all "no" or NO during normal fire monitoring, and therefore block 108.
By checking the work RAM 1, it is determined whether it is necessary to create a control command for the nth terminal. If the fact that a control request to the nth terminal is issued is not stored in the work RAM 1 during the polling operation, a normal state information request instruction code is created (block 109).
After that, if it is stored, after the corresponding control instruction code is created (block 110), the corresponding terminal number n of RAM1 is erased (block 111), and then the nth address code is added to the instruction code. Send to signal line L (block
112).

When the status information in response to the sent command code is received from the nth terminal device, it is sent to a random
Stored in area n of access memory RAM2 (block 11
3), and the test result code (T flag) in the status information
Is determined (block 114). In this case, the T flag does not exist because it is a normal state monitoring operation and not a test operation. Therefore, referring to ROM3, whether the state information is a signal from the sensor (block 115). , It is judged whether it is a signal from the sensor (block 116), and if it is a sensor, the fire discrimination value corresponding to the sensor is read from the ROM 2 (block 117), and it is compared with the status information to determine the fire discrimination value. Whether or not there is a fire is determined by determining whether or not the above (block 11
8) Also, if it is a sensor, it is judged whether or not there is a fire signal in the status information (block 119), and if it is a fire, the fire area is displayed and the main and district sounds are processed. (Block 120).

Here, the sensor is a type of fire detector that outputs an analog amount, and it is possible to obtain various status information based on the analog amount. Also, does the sensor have a fire signal? The one that outputs only an ON / OFF signal, which does not exist, will be referred to.

If it is neither a sensor nor a sensor, but the status information of the terminal, such as the status information that the control circuit of the repeater is operating, decode it and display the status of the terminal. (Block 121). After that, through blocks 122, 123 and 102, the polling operation is started for the next terminal number.

In blocks 120 and 121, if there is a terminal to be controlled, the terminal number and the control content (command) are
The data is stored in the RAM1, and when the next nth terminal is polled, it is determined in block 108 that control is required, and a control command code is sent to the nth terminal (blocks 110, 111, and
112) It will be.

Next, the operation during the test will be described.

When a test start switch (not shown) provided in the operation part OP is operated, a test start interrupt occurs (block 10
3 "yes" or YES), test start processing program 20
Go to 0, the details of this test start processing program 200
This is shown in the flow chart of the figure.

In addition, here, the test is started by a person operating the test start switch, but the test is automatically started once a day or once a week, for example. It is also possible to interrupt, and even in the case of automatically interrupting in this way, the determination in block 103 is YES.

In the flowchart shown in FIG. 3, k is used instead of n as a general terminal number of N terminal devices. First, by referring to the contents of ROM3, it is judged whether or not the kth terminal is the test object (block 20).
3). Since the device under test is a repeater to which an analog sensor or a fire detector is connected, the other terminal devices are excluded from the test target. If the kth terminal is not the terminal device to be tested, the decision block 21
After 0 and 202, the next terminal goes to the judgment as to whether it is the terminal under test or not, and if it is the terminal under test, then the status information of the kth terminal is read from RAM2 (block 204). (YES in block 205), and ROM2 to k
Read the test start tolerance of the terminal No. (block 206), R
The state information of the kth terminal read from AM2, that is, the analog amount of the fire phenomenon detected by the fire detection unit FD is compared with the test start allowable value of the kth terminal read from ROM2 (block 207). .

Here, the test start allowable value is set to a value between the reference value for judging that a fire has occurred and the value in the normal state, so it is judged that there is still a fire, such as when the analog amount is gradually increasing. Too early to set, but the test is set to a value that should be interrupted.

If the determination at block 205 is not a sensor, then it is a sensor, so a determination is made as to whether there is a fire signal condition (block 208). Here, the fire signal state means a state where there is a fire signal in the state information, that is, when it is on, or a state where the storage circuit or the storage timer is operating in response to the fire signal.

If the determination in block 207 is less than or equal to the allowable value, or if the determination in block 208 is not a fire signal state, the kth terminal is stored in RAM1 as a test start terminal that may start the test (block 209). , Go to a similar determination in block 203 for the next terminal number. In this way, when it is determined that all the test target terminals are test start terminals (YES in block 210), the in-test indicator lamp provided in the display unit is turned on (block 211), and the test timer is used. TM1 is turned on, the test start interrupt by the test start switch is released (block 220), and the test start processing program is terminated.

If there is at least one terminal that the judgment of block 207 is larger than the allowable value or the judgment of block 208 is the fire signal state, such a terminal is found because the terminal test is not performed. All the numbers of test start terminals stored in RAM1 up to this point are erased (block 212), and the acceptance of test start is displayed on the display DP (block 21).
3), Release the test start interrupt by the test start switch of the operation unit and terminate the test start processing program.

If the test start processing program determines that the test can be started, the process returns to FIG. 2 and returns to the polling operation from block 102.

The test start interrupt has been cleared, so the determination at block 103 is NO, and a determination is then made as to whether a test end interrupt was made (block 104). This test end interrupt is generated by operating the test end switch provided in the operation unit when it is desired to forcibly end the test.

When a test end interrupt occurs, the test end processing program 300 is visited, and the details of the test end processing program 300 are shown in the flowchart of FIG. In the test end processing program 300, all terminals to be tested (blocks 303 and 305) are stored in the RAM 1 as test required terminals (block 304), and the block 211 in FIG.
Turn off the test-indicator light lit in (block 306),
Then, the test end interrupt is released, and then returning to FIG. 2, the test timer TM1 turned on in block 220 is cleared (block 132 in FIG. 2). As a result, the judgment in block 107 becomes YES during the next normal fire monitoring polling operation, the test end command code is created in block 107a, and the test end command is transmitted to each terminal device ( Blocks 111 and 112).

If the test end interrupt did not occur (block 10
(NO of 4) Next, it is judged whether or not the test timer TM1 is operating (block 105). Since the test timer TM1 is turned on in the block 220, next, in the block 130, the test timer TM1 is turned on. It is determined whether or not the time measured in (1) has reached a predetermined time. Since the predetermined time has not yet passed, the routine goes to block 106, where it is judged whether or not there is a memory in the RAM 1 as the test start terminal as described in block 209. RA is the terminal as the test start terminal
If it is registered in M1, after the test start instruction code is created (block 106a), the memory of the start of test required for the relevant terminal number in RAM1 is erased (block 111), and the relevant address code is added to the instruction code. It sends it to the traffic light L.

After that, the terminal starts the test operation in response to the test start command, and the corresponding return information from the terminal is stored in RAM2.
Is stored in the corresponding address area (block 113). The receiver side determines whether or not the stored information has a T flag indicating that it is test information (block
114), if there is a T flag, nothing is done here and the process moves to polling for the next terminal number (blocks 122 and 10).
2). After that, when the time measured by the test timer TM1 has passed a predetermined time (YES in block 130), the RAM2 is then read from the terminal.
The test result processing program 400 is executed on the basis of the test information collected in 1. The details of the test result processing program 400 are shown in the flowchart of FIG.

Here, the predetermined time in block 130 is set to be longer than or equal to the time required until all terminals can send stable test information. Also during this predetermined time,
As will be described later, since information from the same terminal can be collected multiple times, the terminal is configured to send the test information at the time of collection.

In the test result processing program of FIG. 4, it is determined whether or not the k-th terminal is the test target terminal based on the contents of the ROM 3 (block 403). If it is not the test target terminal, the same determination is made for the next terminal. Move on to. If it is the terminal under test, the state information of the kth terminal is read from the RAM 2 (block 404), and then it is determined whether or not the T flag is included in the information. If there is no T flag, the fact that the kth terminal is not responding to the test is stored in the RAM1 (block 40).
6) Turn on the indicator light corresponding to the terminal that has not responded to the test, that is, the terminal lamp that does not respond to the test (block 40).
7) and move to the determination at block 403 for the next terminal.

If there is a T flag in the judgment of block 405, ROM3
It is determined whether the corresponding terminal is a sensor or not by referring to the content of (block 408). If it is not a sensor, it is a sensor, and therefore it is determined whether or not the test result is normal, that is, whether or not the ON signal is normally output as a result of the test (block 409). If it is a sensor, the upper limit value and the lower limit value for determining the test result of the kth terminal are read from the ROM2 (block 410), and the sensor status information at the time of the test read from the RAM2, that is, the sensor fire. It is determined whether the output of the phenomenon detection unit is within the reference values (block 411).

If the determination of block 409 is normal or the determination of block 411 is within the range of the reference value, the terminal is determined to be normal as a test result, while the determination of block 409 is abnormal or block 411. If the judgment is out of the range of the reference value, the terminal is judged to be abnormal as a test result, the fact that the kth terminal is abnormal is stored in the RAM 1 (block 412), and the abnormal terminal is displayed on the display unit DP. The light is turned on (block 413) and then the test result determination for the next terminal is performed.

The test non-responsive terminal indicator light in block 407 and the abnormal terminal indicator light in block 413 can be shared as a terminal failure indicator light.

When the determination of the test results for all terminals is completed in this way (YES in block 414), the process goes to the test end processing program 415. This test end processing program 415 is
Test termination processing program 30 shown in FIGS. 1 and 5
Same as 0. That is, for all the terminals to be tested (blocks 303 and 305), the terminals to be tested are stored in the RAM 1 (block 304), and the in-test indicator light of the display unit turned on in block 211 of FIG. 3 is turned off (block). 30
6). Then, returning to FIG. 4, R is executed in blocks 406 and 412.
After printing the abnormal terminal number and the test non-response terminal number stored in AM1 and sounding an abnormal sound (block 416),
The abnormal terminal number and the non-test response terminal number stored in the RAM1 are erased (block 417).

Then, the test timer TM1 is cleared (block 13
2) Return to normal fire monitoring operation.

Finally, the operation relating to the test of the terminal equipment suitable for use in the disaster prevention equipment of the present invention will be described with reference to the flowchart of FIG. 6 by taking a sensor, that is, an analog sensor as an example. However, the terminal device is not limited to the one shown in FIG. 6 and various devices can be used.

A test start interrupt occurs on the receiver side (block in Fig. 2
103), a test start instruction code is created (block 106a in FIG. 2), the instruction code is sent to the traffic light L (block 112 in FIG. 2), and when it is received by the terminal device, the terminal device The side determines whether it matches the self-address stored in, for example, ROM 21 (block 502), and if so, then decodes the received instruction code, which causes the test start instruction. (Block 503) or a test end instruction (block 504). Since this is a test start command,
The detection output of the fire detection unit FD is stored in the RAM 22 in order to store the detection output immediately before the start of the test (block 505),
Then, the test circuit TC and the timer TM21 are turned on (block 506). When the test circuit is turned on, for example, a heater or the like heats the fire detection unit FD in order to test whether or not the fire detection unit including the thermistor normally performs fire detection. After that, the detection output stored in the RAM 22 is read and sent to the signal line L (block 507).

The instruction code transmitted from the receiver next is the state information request instruction code created in block 109 of FIG. This is because the test start interrupt has already been cleared as described in block 211 of FIG. As a result, the determinations in blocks 503 and 504 are both NO.
And the timer TM21 is still running (block
508: YES), the detection output of the fire detection unit FD stored in the RAM 22 is again sent from the terminal device (block).
507).

In this way, the terminal device that received the test start command
While 21 is operating, the detection output of RAM22 is sent.
This is because the detection output immediately before the start of the test is sent until the transient and unstable detection output of the fire detection unit FD at the start of the test becomes stable, so that the receiver side does not make an erroneous judgment. . Therefore, the set time of the timer TM21 is set slightly longer than the time required for the fire detection unit FD to stabilize.

When the timer TM21 times out, the status information request instruction code transmitted next from the receiver is NO in block 508.
After that, it is determined in block 509 whether or not the test is in progress, and since the test is in progress, that is, the test circuit is ON,
This time, the detection output of the fire detection unit FD is added to the T flag indicating that it is the status information at the time of the test and sent to the signal line L,
In this way, stable test information is returned to the receiver, and also for the status information request command code sent back from the receiver, the same detection output with T log added is also returned. To be done.

Then, after a predetermined time has passed on the receiver side (block 130 in FIG. 2), the test result processing program 400 is executed, and the test end instruction code created in block 107a is transmitted from the receiver side. And (YES in block 504) the test circuit is turned off and the timer TM21 is turned on (block 51
1), and the detection output immediately before the start of the test stored in the RAM 22 in block 505 is sent to the signal line L (block 50).
7).

Next, when the status information request instruction code is transmitted from the receiver side and the timer TM21 is operating, block 508
Similarly, the contents of RAM22 are returned via YES and the timer TM21
When is turned off, the normal monitoring operation is returned to and the detection output of the fire detection unit is sent (block 51).
2).

[Effects of the Invention] As described above, according to the present invention, based on the test start command, the timer means is energized, the test start command is automatically transmitted, and the test result information collected from the terminal device is displayed. Since the processing is automatically performed, there is an effect that the operator does not make a mistake in the judgment. In addition, since the timer means collects test result information and processes them within a predetermined time, and automatically displays and warns in case of abnormality, it is not necessary for the operator to wait until the end of the test. It also has the effect of not having it.
