Description

  The present invention relates to a fire alarm facility.

  Buildings, etc., which are predetermined fire prevention objects, are obliged to install fire alarm equipment as fire fighting equipment. In addition, it is obliged to periodically check the fire alarm equipment, and it is necessary to check whether the fire detector operates normally and issue a fire alarm and to submit the result of the check to a fire department or the like. In this way, maintenance and management of fire fighting equipment is achieved.

  Smoke detectors, heat detectors, etc. are used as fire detectors. To operate the heat detectors, a cylindrical chamber is attached to the end of a long rod as an operation tester. A heating tester for applying heat by a heater or the like is brought into contact with the heat sensor to operate the heat sensor. In order to operate the smoke detector, the smoke detector that generates pseudo smoke in the chamber is brought into contact with the smoke detector installed on the ceiling surface or the like, and the smoke detector is operated.

  In order to carry out such inspection work of fire detectors and to eliminate omission of inspection of fire detectors, a system for reading out information such as the model number, year of manufacture, manufacturing number, etc. of each fire detector is known. It has been proposed to use an IC tag that can read and write information in a non-contact and power-saving manner using waves (see, for example, Patent Document 1 and Patent Document 2).

  By the way, at the time of inspection work to individually operate the fire detectors installed in the building, RFID tags are attached to each fire detector, and individual numbers etc. are stored there, and the detector tester reader An inspection work has been proposed to collect information on fire detectors that have been read out and operated.

  It is not possible to determine which fire detector has output a fire signal simply by collecting information on the fire detector by this detector tester.

  The proposed example has a problem that the operator cannot visually confirm the state of the fire signal in the inspection work of the fire detector.

  In addition, the above-mentioned proposed example has a problem that in the inspection work of the fire detector, the information on the fire detector tester cannot be accurately compared with the information on the fire receiver.

  Furthermore, the proposed example has a problem in that stored information may not be accurately extracted in consideration of the possibility that information in the inspection operation of the fire detector is falsified.

  A first object of the present invention is to provide a fire alarm facility that allows an operator to visually confirm the state of a fire signal in the inspection work of a fire detector.

  The second object of the present invention is to provide a fire alarm system capable of accurately comparing the information of the fire detector tester and the information of the fire receiver in the inspection operation of the fire detector.

  A third object of the present invention is to provide a fire alarm system that can accurately retrieve stored information without falsifying information in the inspection work of the fire detector before storage.

The fire alarm system of the present invention reads the ID of the fire detector and the time information obtained by the fire detector tester from the ID of the fire detector from the tester of the fire detector. Information reading means for reading the time information when the fire signal is generated, the recovery information, and the time information when the recovery information is generated from the fire receiver, and the time when the fire detector tester acquires the ID of the fire detector Sorting means for sorting the information, the time information when the fire signal is generated, and the time information when the recovery information is generated, and the alarm information including the ID of the fire detector and the time information of acquiring the ID of the fire detector Data that creates data in the order in which the sorting means sorts by time by integrating the fire signal, the time information when the fire signal occurred and the recovery information, and the line information consisting of the time information when the recovery information occurred Generating means, display means for displaying data obtained by integrating the alert information and the line information, and the alert information and the line information are alternately generated in the data created by sorting by the sort means. If not, it is characterized by comprising a signal processing device having a judging means for judging that it is abnormal.

In the said Example, it is a figure which shows the result (counting result after an inspection) which combined FIG. 6 and FIG.

  The modes for carrying out the invention are the following examples.

  FIG. 1 is a block diagram showing a fire alarm system 100 that is Embodiment 1 of the present invention.

  The fire alarm system 100 includes heat detectors SE1, SE2, and SE3, IC tags T1, T2, and T3, a fire receiver 20, a plurality of sensor lines 30, and a heat test as a fire detector tester. Device 40, signal processing device 50, and printer 60.

  The heat sensor SE1 is a differential spot type heat sensor that catches a temperature rise due to heat generated by a fire, for example, and has an IC tag T1 attached thereto. Further, when the heat detector SE1 operates, an operation indicator lamp (not shown) is turned on, and a fire signal is output to the sensor line 30. When a fire is detected, a so-called switching circuit causes a low impedance state between the two wires of the common line and the signal line of the sensor line 30, whereby a fire signal is sent to the fire receiver 20. The fire signal output method need not be limited to this method. The required number of heat sensors SE1 are connected to the sensor line 30 in accordance with the size of the monitoring section.

  The IC tag T1 is affixed to the outer peripheral surface of the main body of the heat detector SE1, and although not shown, an IC chip portion and an antenna portion are provided in a planar shape on a sheet-like substrate. In the IC chip portion of the IC tag T1, a unique identification number for individually identifying the heat detector SE1 is stored. This unique identification number is a number for distinguishing individual fire detectors in the same equipment and further in the same line. Further, the IC tag T1 does not have a power supply by itself, operates with electric power given by an electromagnetic induction wave from a reader 41 provided in the heating tester 40, and transmits an identification number as identification information. Here, since the IC tag T1 is provided in a form to be affixed with a seal, it can be easily affixed to a sensor installed in a building or the like as well as at the time of manufacturing the heat sensor SE1.

  Further, the IC tag T1 is sufficient to hold only the unique identification number of the sensor, but information such as the model number and the manufacturing year of the heat sensor SE1 may be stored at the same time. By doing so, the stored information can be used when so-called type revocation or when it is desired to collect defective products, and can be used in a different scene from the inspection work. These information may be read by the reader 41 at the same time.

  Note that as the unique identification number, a large number such as no other fire detector having the same number, for example, a number up to 2 to the 45th power may be prepared. By using such a large number as the unique identification number, even if the IC tag T1 is randomly attached to the heat sensor SE1, the identification number does not overlap. Further, even if a large number of IC tags including the IC tag T1 are manufactured at one time, there is no duplication of identification numbers, which is advantageous in terms of cost, and can be introduced in a small facility without a heavy burden.

  The heat sensor SE2 stores identification information unique to the heat sensor SE2, and an IC tag T2 similar to the IC tag T1 is attached. The heat sensor SE3 has a unique characteristic of the heat sensor SE3. Identification information is stored and an IC tag T3 similar to the IC tag T1 is attached.

  In the following description, the heat sensors SE1 to SE3 will be representatively described by focusing on the heat sensor SE1, and if necessary, they will also be described in the heat sensors SE2 and SE3.

  The fire receiver 20 receives a fire signal output from the heat detector SE1 via the sensor line 30 and performs a necessary fire operation such as a fire alarm, and detailed description is omitted. In addition to displaying the occurrence of a fire on the board, the so-called main sound is sounded, and the sound of the necessary district sound is controlled (in the form of simultaneous ringing or district ringing).

  The fire receiver 20 is a so-called P-type. Since the fire signal is output by setting the sensor line 30 to the low impedance state, the fire receiver 20 is provided with a receiving circuit (not shown) for monitoring this state and detecting the fire signal. .

  Further, the fire receiver 20 is provided with a storage device M1 via a terminal portion 21. The storage device M1 may be fixed in the fire receiver 20, but is connected to the terminal portion 21 of the fire receiver 20. Detachable.

  The sensor line 30 is connected to a receiving circuit of the fire receiver 20 by being drawn into the housing of the fire receiver 20 and connected to a predetermined terminal.

  The heating tester 40 is an operation tester used for checking the heat sensor SE1, and is supplied from a heating element such as a heater or a heat storage body provided in a hood provided at the tip of the rod to the heat sensor SE1. The heat is transferred and the heat sensor SE1 is operated. Here, the heating tester 40 is used for the heat sensor SE1, but when the fire sensor is a smoke sensor, a smoke tester is used, and a test corresponding to the type of the fire sensor is used. A vessel is used.

  The heating tester 40 is provided with a reader 41 and a storage means 42. The reader 41 reads the identification information (identification number) stored in the IC tag T1 in a non-contact manner using an electromagnetic induction wave. The storage means 42 stores identification information such as an identification number read by the reader 41 as notification information, and also stores the read time.

  The reader 41 wirelessly receives the unique identification information of the heat sensor SE1 from the IC tag T1 after the electromagnetic induction wave is transmitted to the IC tag T1.

  The signal processing device 50 includes a reading unit 51, a sorting unit 52, an inspection form data creation unit 53, an encryption unit 54, a storage unit 55, a display unit 56, a print start button 57, and a time update unit. 58.

  The reading means 51 reads the fire detector ID and the time information acquired by the heating tester 40 from the ID of the fire detector as alarm information from the heating tester 40, and also reads the fire signal and the fire signal. This is means for reading from the fire receiver 20 the time information, the recovery information, and the time information at which the recovery information has occurred as line information. The recovery information is information indicating that the fire signal that has occurred is erased and returns to the monitoring state, or information indicating that manual recovery has been performed.

  The sorting means 52 is a means for sorting the time information when the fire detector acquires the ID of the fire detector, the time information when the fire signal is generated, and the time information when the recovery information is generated.

  The inspection sheet data creation means 53 includes the fire detector ID, the time information when the fire detector ID was acquired, the fire signal, the time information when the fire signal occurred, the recovery information, and the time information when the recovery information occurred. Are means for creating data as the inspection slip 61 in the order in which the sorting means 52 sorts them.

  The encryption unit 54 is a unit that encrypts the information read by the reading unit 51. The storage unit 55 is a unit that stores the information encrypted by the encryption unit 54.

  The display means 56 is a device that displays data obtained by integrating FIGS. 3, 6 and 8 shown in FIG.

  The print start button 57 is a button for causing the printer 60 to start printing the inspection slip 61 and the like.

  The time update means 58 is means for updating the time of the clock provided in the heating tester 40 and the time of the clock provided in the storage device M1 to the current correct time.

  In addition, you may make it provide a smoke detector etc. instead of a heat sensor as a fire detector. Further, a heat sensor and a smoke sensor may be mixed.

  The printer 60 is a means for printing the inspection slip 61.

  Next, the operation of the above embodiment will be described. First, the operation on the fire receiver 20 side will be described.

  FIG. 2 is a flowchart showing the time adjustment operation performed before inspection in the above embodiment.

  In S1, the heating tester 40 is connected to the signal processing device 50, and the time of the clock provided in the heating tester 40 is updated to the current correct time in S2. In S3, the updated time is stored in the storage means 42. The update time stored in the storage means 42 becomes the starting point for the expiration date of the time update of the clock provided in the heating tester 40. In step S4, the heating tester 40 is removed from the signal processing device 50.

  In S5, the storage device M1 is connected to the signal processing device 50, and the time of the clock provided in the storage device M1 is updated to the current correct time in S6. In S7, the updated time is stored in the storage device M1. The update time stored in the storage device M1 is the starting point for the expiration date of the time update of the clock provided in the storage device M1. In step S8, the storage device M1 is removed from the signal processing device 50.

  That is, before checking the fire detector, the time stored in the fire detector tester and the time stored in the storage device of the fire receiver 20 are substantially matched to each other. That is, instead of storing the current accurate time in both sides, one time may be adjusted to the other time, and the difference between both times is detected and this difference is referred to in post-processing. It may be.

  FIG. 3 is a diagram showing the correspondence between sensor IDs and sensor names in the above embodiment.

  FIG. 4 is a flowchart showing the operation of the fire receiver 20 in the above embodiment.

  In the operation preparation stage shown in FIG. 4, the fire receiver 20 is set to a so-called maintenance mode. This maintenance mode is a mode for automatic recovery immediately after receiving a fire signal. That is, the function of the fire receiver 20 usually cannot automatically recover the fire signal generated by the heat detector. In other words, if the first fire signal is received via the same sensor line 30, the second fire signal cannot be received unless a recovery operation is performed. However, at the time of inspection work, it is set to the maintenance mode and set to automatically recover immediately after receiving a fire signal. Thereby, it is not necessary to arrange an operator for making a recovery input in the vicinity of the fire receiver 20 at the time of inspection work. If automatic restoration is not required, an operation to manually restore the fire signal while attaching another worker to the board of the fire receiver 20 and contacting the worker operating the heat detector, Another worker can do it.

  First, the reader 41 is activated by operating a switch (not shown) provided in the heating tester 40. Then, the heating tester 40 is brought close to the heat detector SE1, and electric power is supplied to the IC tag T1 provided in the heat detector SE1 to be heated by the electromagnetic induction wave. The unique identification number is read without contact. The read identification number is stored in the storage means 42 provided in the heating tester 40 as notification information, and the time at which the identification number is read is read from the clock provided in the smoke tester 40. Is stored in the storage means 42. Thereafter, the heat sensor is sufficiently heated, and the heat sensor SE1 operates to output a fire signal.

  The operation of reading the identification information of the heat detector SE1 by the IC tag reader 24 is non-contact and can be performed semipermanently. If the interval between the IC tag reader 24 and the IC tag T1 is short, the identification information can be read out. In addition, since the operation test can be performed so as to bring the heating tester 40 almost into contact with the heat sensor SE1, power consumption in the heating tester 40 can be reduced. Further, since there is a sufficient interval between the heat sensor SE1 and the heat sensor SE2 installed next to the heat sensor SE1, the two heat sensors SE1 and SE2 do not emit the identification information at the same time. Even if it is emitted at the same time, the heating tester 40 does not receive the identification information from the heat sensor SE2 located far from the heating tester 40.

  Next, the heating tester 40 is brought close to the heat sensor SE2, and power is supplied to the IC tag T2 provided in the heat sensor SE2. From the IC tag T2, a unique identification number of the heat sensor SE2 is obtained. The data is read out in a non-contact manner and stored in the storage unit 42, and the time when the identification number is read out is stored in the storage unit 42, and the heat detector SE2 operates. As for the heat sensor SE3, the unique identification number of the heat sensor SE3 is read from the IC tag T3 in a non-contact manner and stored in the storage means 42, and the time when the identification number is read is stored in the same manner as described above. Stored in the means 42, the heat sensor SE3 is activated.

  In this work phase, the activated thermal sensors SE1, SE2, SE3 output a fire signal to the fire receiver 20 via the sensor line 30 at that time.

  Here, in S11 shown in FIG. 4, it is checked whether or not a predetermined period (for example, 0.5 seconds) has elapsed. If the predetermined period has elapsed, it is checked in S12 whether there has been a change. That is, it checks whether a fire signal has been received or recovery has been detected. If a fire signal is received or recovery is detected, the changed information (information indicating that a fire signal has been received or information indicating that a recovery operation has been performed) is stored in S13. It is stored together with the time of occurrence read from the clock provided in M1. Then, the process returns to S11.

  On the other hand, if it is determined in S11 that the predetermined period has not elapsed, and if it is determined in S14 that the power-off operation has been performed, the process ends, and the power-off operation has not been performed. If determined, the process returns to S11.

  FIG. 5 is a flowchart illustrating an operation in which the heating tester 40 reads the identification number of the heat detector in the second embodiment.

  When the heating tester 40 is activated, in S11, it tries to read the identification number, and if the identification number can be acquired (S12), whether the acquired identification number overlaps with the already acquired identification number, The determination is made at S13. If it is determined that there is no duplication, the acquired identification number is stored in S14, and it is determined in S15 whether or not a predetermined period (for example, 5 seconds) has elapsed. If 5 seconds have elapsed, the process returns to S11. If five seconds have not elapsed, it is determined in S16 whether an off operation has been performed. If it is determined that the off operation has been performed, the process ends. If it is determined that the off operation has not been performed, the process returns to S15 and waits for 5 seconds.

  On the other hand, if it is determined in S13 that there is a duplication of the identification number, the duplication number function C is incremented by 1, and in S18, whether or not the duplication number C has reached a predetermined constant K (for example, two times). Judging. If the overlap count C has not reached 2, the process proceeds to S15 and waits for 5 seconds. If it is determined in S18 that the number of times of duplication C has reached 2, in S19, the IC tag reader 24 waits for a predetermined time, for example, 1 minute, and if the waiting time of 1 minute elapses, in S20, The overlap count C is initialized to 0, and the process returns to S11. The waiting time in S19 is preferably the time from when the tester of the fire sensor is applied to the fire sensor until the fire sensor operates.

  In addition, since the antenna of the reader provided in the tester of the fire detector is substantially ring-shaped, during the fire sensor operation test, whatever the angle of the fire detector tester is, The distance between the antenna of the IC tag and the antenna of the tester of the fire detector is within an appropriate distance. Therefore, the information stored in the IC tag can be reliably and quickly read by the tester of the fire detector.

  The occurrence time read in S13 is not deleted. In S14, both information and time are stored.

  FIG. 6 is a diagram illustrating an example of the date and time when the tester 40 acquires the ID of each sensor in the above embodiment.

  The relationship between the acquired sensor ID and the sensor name is shown in FIG. 3 and FIG. 6, it can be known which sensor has its ID acquired.

  FIG. 7 is a flowchart showing the operation of the signal processing device 50 and encryption of stored data in the above embodiment.

  In S21, the signal processing device 50 is activated to read and save each piece of information. That is, each information (information including re-reading of data) is read from the storage means 42 and the storage device M1 of the tester 40, and the information is combined and stored.

  In S22, the time of the clock is confirmed. That is, it is confirmed that the clocks of both the clock provided in the heating tester 40 and the clock provided in the storage device M1 are updated, and the update times of both the clocks are the same. Make sure that there is. In S23, the information (fire signal and recovery signal) acquired from the fire receiver 20 and the information (heat detector ID) acquired from the heating tester 40 are sorted in time order. In S24, the order of occurrence events is confirmed. That is, the order of the time when the ID of the heat sensor is acquired and the time when the fire signal is generated is confirmed. When confirming the order of the occurrence events, it is not necessary to confirm the order of the time when the recovery signal is received.

  In S25, it is determined whether there is an abnormality. For example, after acquiring the ID of a predetermined sensor, the case where the ID of another sensor is acquired instead of the fire signal is abnormal. That is, it is abnormal when the alert information and the line information are not alternated. Moreover, it is abnormal when the fire signal and the recovery signal of the same line are not continuous. If there is an abnormality, the abnormality result is displayed on the display means 56 in S26. In S27, information on the number of installed heat sensors is compared with information on the number of read information. As a result of this comparison, if the number of read information is less than the number of installed heat detectors, if it is determined in S28, the information to be read is missing, and the missing information in S29. Is what information (information of which sensor). If it is determined that there is no missing information in S28, the display means 56 is displayed in S30 that the process has been completed normally.

  Then, in S31, it is determined whether or not an output operation has been performed by a worker. If it is determined that an output operation has been performed, an inspection slip 61 is output in S32. If it is determined that the output operation has not been performed, in S33, it is determined whether or not the storage operation has been performed by the worker. If it is determined that the storage operation has been performed, in S34, the data is encrypted and the encrypted data is encrypted. The saved data is saved in S35. Note that the inspection form can be output only when it ends normally, and cannot be output when it ends abnormally.

  If it is determined that the storage operation has not been performed, and it is determined in S36 that the operator has performed a power-off operation, the process ends. If it is determined that the power-off operation has not been performed, the process returns to S31.

  In FIG. 8, in the above embodiment, the line information stored in the storage device M of the fire receiver 20 may be displayed on the display means 56 provided in the signal processing device 50, for example.

  The lines in the diagram shown in FIG. 8 are a line indicating “fire signal generation” and a line indicating “recovery”, which are displayed repeatedly. That is, when the signal processing device 50 monitors the fire signal at a fixed period and detects that the fire signal has occurred, the word “fire” is displayed on the display means as shown in a circle in the first line of FIG. 56. When the line where the fire signal is generated is then automatically restored to fire or manually, the “fire” displayed so far is erased in the next line (second line). In this case, a fire signal is generated on the line 3, indicating that the fire has been restored. That is, it indicates that the inspection work on the line 3 has been normally completed.

  In addition, “9:35:43” shown in the first line of FIG. 8 indicates the fire signal generation time, and “9:35:50” shown in the second line of FIG. 8 indicates the time when the fire was restored. Show. In other words, the time of the line where “Fire” is displayed on one of the lines indicates the fire signal occurrence time, and the time of the next line (line where “Fire” is not displayed on any line) Indicates the fire recovery time.

  Thereafter, in the third line of FIG. 8, “fire” is displayed on the line 2, that is, it indicates that a fire signal has occurred on the line 2. In the fourth line of FIG. Since "Fire" is erased, it indicates that the fire has been restored on line 2. Note that when a fire is restored, not only “fire” is deleted to the right of the line 2 as described above, but it is also possible to clearly indicate that the fire has been restored, such as “recovery”.

  Similarly to these, the fifth and sixth lines in FIG. 8 indicate that a fire signal has been generated on the line 1 and that the fire recovery has been executed normally.

  FIG. 9 shows the result of combining FIGS. 3, 6, and 8 in the above embodiment, and this may be displayed on the display means 56.

  The data indicating the correspondence between the sensor ID shown in FIG. 3 and the name of the sensor, the data indicating the date and time when the ID of each sensor shown in FIG. 6 is acquired, and the inspection result by the display means 56 shown in FIG. The data is integrated, and the sorting means 52 sorts these data by time. As a result, the result shown in FIG. 9 is displayed. In the first line of FIG. 9, the name of the first inspected sensor (sensor 1) and the date and time when the ID of the sensor was read are displayed. In the second line 9, the date and time when the fire signal occurred and the name of the line (line 3) where the fire signal occurred are displayed. The fire detector 1 is included in the line 3. The third line in FIG. 9 indicates that the fire has been restored on the line 3 by leaving the date and time of the fire restoration and the right side of the name of the fire restored line (line 3) blank. The display portion indicating these states is a portion surrounded by a square in FIG.

  As with the sensor 1, the name of the next inspected sensor, the generation of a fire signal, and the fact of the fire recovery are described in the fourth, fifth and sixth lines of FIG. 9, and the name of the next inspected sensor. The occurrence of a fire signal and the fact of fire recovery are described in lines 7, 8 and 9 in FIG.

  In FIG. 9, if the inspection ends normally, it is not necessary to display a line in which the recovery operation has been executed (for example, a line indicating that the recovery operation has been performed at time 9:35:50). However, for example, when the second fire detector connected to the same line is checked without performing the recovery operation after the first fire detector generates a fire signal for a certain line, the above 2 Since the first fire detector cannot generate a fire signal, the signal processing device 50 determines that the second fire detector does not generate a fire signal, and the second fire detector does not generate a fire signal. The sensor does not indicate that a fire signal has been generated. In this case, as shown in the above embodiment, if the line indicating that the recovery operation is executed is displayed if the recovery operation is executed, the line indicating that the recovery operation is executed is not displayed. The operator can recognize that the second fire detector has been inspected without being operated. After the recovery operation, the second fire detector can be confirmed. On the other hand, in the above case, if the line indicating that the recovery operation is executed is not displayed even if the recovery operation is executed, it is determined that the second fire sensor has been confirmed and has failed. Therefore, even if the second fire detector is normal, it is replaced and the normal fire detector is wasted.

  According to the above embodiment, if the fire signal is not restored, the next fire signal cannot be received, so that the fire restoration timing can be confirmed. That is, in the said Example, the presence or absence of the fire restoration after fire signal generation | occurrence | production can be confirmed.

  In addition, according to the above embodiment, after the fire signal is received by the fire receiver 20, the fire recovery signal is normally generated. However, the fire recovery signal may be used for confirming the order of the occurrence events in S24. When it is not a normal end, it is only necessary to confirm the recovery timing, and it is not necessary to use it for the fire signal confirmation. In other words, the restoration signal is used for confirming the restoration timing, and it is not necessary to match the numbers of the fire signal and the restoration signal. Even if it does not recover, it will not be abnormal in S25 of FIG. 7, but if there is no recovery, the subsequent inspection cannot be performed, resulting in an abnormality. Therefore, no recovery signal is required. Since the restoration signal is not used for the fire signal confirmation, the number of signals to be processed is reduced, so that the processing becomes faster.

  Furthermore, according to the above embodiment, in order to accurately compare the timing of information acquisition from each fire detector and the detection of a fire signal at a fire receiver and the generation of a recovery signal, the time in the tester It is assumed that the information and the time information in the storage unit match each other. In the above embodiment, the time of each clock is set, so that the above comparison can be performed accurately.

  In addition, if the data acquired in the inspection is falsified, the inspection for fire detection that has not been inspected is also completed normally, and the reliability of the inspection operation is lost. According to the above embodiment, since the information (data) from the program is encrypted when it is stored in the storage device M1 (HDD or the like), the data on the storage medium cannot be altered or altered, and the past Test results can be stored correctly.
