Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a disaster prevention monitoring system and a terminal for connecting a plurality of terminals having an abnormality detection unit such as a fire and a gas leak to a transmission path from a receiver, and identifying an abnormality occurrence location by a unique address set in the terminal It relates to the address setting method.
[0002]
[Prior art]
Conventionally, a terminal equipped with a transmission function such as an analog fire detector with a unique address set for the transmission line drawn from the receiver is connected, and an alarm display that identifies the location of the fire using the unique address of the terminal when a fire is detected is displayed. Disaster prevention monitoring system to perform is known.
[0003]
In such a disaster prevention monitoring system, an analog fire detector is attached to the detector base in the middle of the construction for which the terminal address is not fixed at the time of facility construction, and the address is not set. Although it is not possible to specify the location of a fire by means of, there are cases in which it is desired to use a method such as basic fire monitoring that receives and alerts a fire.
[0004]
When a terminal is installed without setting an address as described above, an address is set again for a terminal that has not been set when the address is determined as the construction progresses.
[0005]
On the other hand, there are the following methods for setting an address in a terminal such as a fire detector.
(1) A method of manually setting an address by using a dip switch or a rotary switch provided in the terminal.
(2) How to configure remotely address from the receiver with the address setting command (JP-A-4-34 61 99 No., JP 2001-13277 No. 9, JP-A-3-139798, and JP-4- 369796, Japanese Patent No. 317985, etc.).
(3) A method of remotely setting an address from an address setter to a terminal by infrared or wireless communication.
[0006]
[Problems to be solved by the invention]
However, the conventional method for setting the address of the terminal has the following problems.
[0007]
First of all, manually setting the address on the terminal requires removing the terminal installed on the ceiling surface etc., which takes time and effort, especially for terminals installed in high places that are dangerous to remove There is also.
[0008]
Also, the method of setting addresses remotely from the receiver requires that the receiver's error monitoring mode be canceled and the address setting mode must be set while the address is being set, during which fire monitoring cannot be performed. is there.
[0009]
Furthermore, the method of remotely setting an address to a terminal by infrared or wireless using an address setting device requires that a dedicated circuit unit such as an infrared light receiving unit or a wireless receiving unit be separately provided in the terminal, and the configuration of the terminal There is a problem that becomes complicated and increases the cost.
[0010]
It is an object of the present invention to provide a disaster prevention monitoring system and a terminal address setting method that enable remote address setting of a terminal installed without determining an address from the receiver side without impairing the abnormality monitoring function. Objective.
[0011]
[Means for solving the problems]
In order to achieve this object, the present invention is configured as follows. The present invention connects a plurality of terminals equipped with an abnormality detection unit such as a fire or gas leak to the transmission path from the receiver, sets a unique address for the terminal, and the terminal detects an abnormality such as a fire. In a disaster prevention monitoring system that identifies the location of an abnormality by address, an abnormality was detected when the receiver recognized that the terminal address that detected the abnormality was a predetermined use-prohibited address. An address setting control unit that enables an address setting operation of the terminal is provided.
[0012]
Therefore, according to the present invention, for example, a fire detector whose address has not been determined at the time of installation is set to a number that is not used as a terminal address. Use it to apply heat and smoke to the fire detector to generate a test report, recognize the address unknown by the receiver for this test report, select the address setting mode, and select the address setting mode Thus, remote address setting from the receiver, specifically, the setting change from the prohibited address to the determined address can be performed.
[0013]
In particular, since the operation of the fire detector is always confirmed during the construction of the equipment, if it is recognized that the address is unknown at the time of this test report, the address set by selecting the address setting mode is selected. Setup work can be done in parallel with test work.
[0014]
Also, even if you select the address setting mode for the fire alarm test notification for which a prohibited address has been set, this address setting mode is performed as a process in the fire monitoring mode, and the fire monitoring mode is canceled. Even if it is in the address setting mode and the address setting is being changed, the fire monitoring process that identifies the location of the fire based on the address is performed if another fire detector reports, and the address setting is performed. Does not impair the fire monitoring function.
[0015]
Here, the address setting control unit displays the selection of the address setting mode and the abnormality processing mode on the screen when recognizing the use-prohibited address of the terminal that detected the abnormality, and when the selection of the address setting mode is recognized, Execute the address setting process of the terminal that detected the abnormality. For this reason, the user can easily select whether or not to set an address as necessary when receiving an abnormality detection of a terminal whose address is unknown.
[0016]
When recognizing the selection of the address setting mode, the address setting control unit displays a currently unused terminal address as a candidate address. For this reason, it is possible to prevent errors such as address duplication by comparing the address determined for address setting with the displayed unused address (empty address).
[0017]
If the address setting control unit recognizes the selection of the abnormal processing mode for the selection screen display of the address setting mode and the abnormal processing mode, or if no selection is recognized within the predetermined time, the use prohibited address An abnormal processing mode for executing alarm processing in the monitoring mode (the same processing as normal alerting) is executed for a terminal for which is set .
[0018]
For this reason, if a fire detector with an unknown address is actually detecting a fire and reporting, if the receiver does not select either address setting mode or error handling mode, a fire will occur after a certain period of time. Alarm processing is performed in the monitoring mode, and the fire monitoring function is not impaired by the address setting function.
[0019]
The use-prohibited address set in the terminal in the disaster prevention monitoring system of the present invention is, for example, the maximum address that can be set in the terminal.
[0020]
The present invention connects a plurality of terminals equipped with an abnormality detection unit such as a fire or gas leak to the transmission path from the receiver, sets a unique address for the terminal, and the terminal detects an abnormality such as a fire. Provides a terminal address setting method for disaster prevention monitoring system that identifies the location of anomalies by address.
[0021]
This terminal address setting method is
Connected to the transmission line in a state where a predetermined use prohibited address set in advance is set in a terminal whose address is not fixed,
When the address is fixed, test the terminal set with the prohibited address,
When an abnormality detection signal is received from a terminal for which the use prohibited address is set by a receiver, the setting is changed to a terminal address for which the use prohibited address has been determined by an instruction from the receiver.
[0022]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is an explanatory diagram showing the overall configuration of the disaster prevention monitoring system of the present invention. In FIG. 1, a transmission path 2 is drawn from a receiver 1 toward a warning area, and repeaters 3-1, 3-2, 3-3 having a transmission function as a plurality of terminals on the transmission path 2. 3. Analog fire detectors 3-4 and 3-5 are connected.
[0023]
In this embodiment, a bell 4-1 is connected to the repeater 3-1 as a control load, a fire door 4-2 is connected to the repeater 3-2 as a control load, and further to the repeater 3-3. An on / off fire sensor 7 is connected. The analog fire detectors 3-4 and 3-5 detect smoke or heat accompanying the fire and send analog detection information to the receiver 1.
[0024]
The receiver 1 is provided with a display unit 5 and an operation unit 6, and the operation unit 6 includes a numeric keypad 6a used for address setting. The receiver 1 can exchange information with a terminal connected to the transmission path 2 by sending a command specifying a preset address. Therefore, the receiver 1 and each terminal are provided with a transmission control function for exchanging commands and information by address designation.
[0025]
The terminal addresses that can be called by the receiver 1 are, for example, addresses 1 to 255. In the present invention, among the addresses 1 to 255, use prohibited addresses that do not use addresses in the system are determined in advance. For example, the address “255” (all 1 in binary code) is used as the prohibited address.
[0026]
Therefore, the receiver 1 controls or exchanges information with a terminal connected to the transmission path 2 by a command using addresses 1 to 254 that can be effectively used as a system. The use prohibition address “255” that is not used as a system address is used as a setting address of a terminal whose address is not determined when a terminal is installed on the transmission path 2.
[0027]
That is, in the disaster prevention monitoring system as shown in FIG. 1, the transmission path 2 is drawn to the receiver 1 at the time of construction work, and in the terminal, for example, analog fire detectors 3-4 and 3-5 are connected. For example, the sensor base is installed on the ceiling side and connected to the transmission line 2, and then the sensor body is mounted on the sensor base.
[0028]
As described above, in the analog fire detectors 3-4 and 3-5, when the sensor body is mounted on the completed sensor base, the sensor body may be mounted when the sensor address is not fixed. is there.
[0029]
When the sensor body is mounted in a state where the sensor address has not been determined, a use prohibition address “255” that is not used as an address in the system is set in advance in the sensor body.
[0030]
Specifically, the use prohibition address “255” is set as an initial setting address at the time of factory shipment of the analog fire detectors 3-4 and 3-5, and the setting is not performed on the site without changing the setting of this address. By attaching to the sensor base on the transmission line 2 side, it is possible to connect to the receiver 1 as an analog fire sensor in which the use prohibition address “255” is set.
[0031]
In the example of the disaster prevention monitoring system of FIG. 1, for example, the address of the analog fire detector 3-5 is set to the use-prohibited address “255”, and the other terminals are set with valid valid addresses. Will be described.
[0032]
When the terminal including the analog fire detector 3-5 having the setting of the use prohibition address “255” is connected to the transmission line 2 and the system is started up by turning on the receiver 1, the receiver 1 sequentially designates the terminal address. Then, polling for sending a polling command for making the terminal state respond is started.
[0033]
However, the analog fire detector 3-5 is set to the use prohibition address “255” that is not used as a system, and therefore does not respond to polling from the receiver 1.
[0034]
The subsequent setting of the determined address for the analog fire detector 3-5 for which the use prohibition address “255” is set is to perform the alarm test of the analog fire sensor 3-5 using the alarm test jig 21. Thus, it is possible to set a fixed address by an operation from the receiver 1.
[0035]
That is, when the analog fire detector 3-5 is a heat detection type, the alarm test jig 21 applies heat, and if it is a smoke detector, smoke is added to perform the alarm operation.
[0036]
The receiver 1 does not poll the analog fire detector 3-5 for which the use prohibition address “255” is set, but the fire alarm by the alarm test jig 21 of the analog fire detector 3-5 is not detected. Perform fire reception processing.
[0037]
That is, the analog fire detectors 3-4 and 3-5 connected to the transmission line 2 detect the fire and generate a fire alarm in a form that destroys the terminal response signal to the polling command from the receiver 1 when a fire is detected. The transmission signal is sent to the transmission line 2. When the receiver 1 receives this fire interrupt signal, it searches for the address of the analog fire detector that issued the fire.
[0038]
However, even if the receiver 1 searches for the alarm detector, the address of the analog fire detector 3-5 is the use-prohibited address “255”, so the receiver 1 recognizes the alarm address that has been issued. The address is unknown.
[0039]
In this way, when it is determined that the address is unknown to the sensor notification, the receiver 1 uses the display unit 5 to display a selection menu screen for selecting the abnormal processing mode or the address setting mode. Looking at this selection menu screen, when the person in charge of the receiver 1 selects the address setting mode, the address setting process using the address setting command is performed on the analog fire detector 3-5 whose address is unknown. It can be carried out.
[0040]
At this time, only the notified analog fire detector 3-5 with unknown address responds to the address setting processing command from the receiver, and the analog fire detector with unknown address not notified does not respond.
[0041]
FIG. 2 is a block diagram of a functional configuration in the disaster prevention monitoring system of FIG. In FIG. 2, the receiver 1 is provided with a receiver MPU 8, the receiver MPU 8 is provided with a display unit 5 and an operation unit 6, and a transmission path 2 is drawn through a transmission control unit 9. ing.
[0042]
The receiver MPU 8 is provided with a monitoring control unit 10 and an address setting control unit 11 realized by program control. The monitoring control unit 10 performs polling by sequentially specifying the terminal addresses connected to the transmission path 2. Also, when a fire interrupt is received due to a fire alarm, it performs address search processing, identifies the sensor address that caused the fire alarm, collects fire detection information, and performs a fire alarm operation.
[0043]
The address setting control unit 11 is activated when an address unknown search result is obtained in the address search for the fire interrupt by the test notification of the terminal for which the use prohibition address is set, for example, the analog fire detector 3-5, and the display unit 5 For example, a mode selection screen 17 as shown in FIG. 3 is displayed.
[0044]
The mode selection screen 17 displays “an address unknown sensor is reporting” as a notification message 18 and a fire processing mode selection menu 19 and an address setting mode selection menu 20.
[0045]
If the operator wants to set an address on this mode selection screen 17, an address setting operation can be performed on an analog fire detector 3-5 whose address is unknown, for example, by clicking on the address setting mode selection menu 20. On the other hand, when the fire processing mode selection menu 19 is selected, fire alarm processing is performed by the monitoring control unit 10.
[0046]
Furthermore, if any mode selection operation is not performed over a certain time on the display of the mode selection screen 17, a fire alarm process is automatically performed by the monitoring control unit 10.
[0047]
Referring to FIG. 2 again, taking the terminal side connected to the transmission line 2 from the receiver 1, for example, the analog fire detector 3-5 as an example, a transmission control unit 12 and a repeater MPU 13 are provided. In the analog fire detector 3-5, a fire detection unit 15 is provided to detect a fire due to smoke or heat and output an analog detection signal.
[0048]
Further, the repeater MPU 13 is provided with a non-volatile memory 16 for storing addresses.
[0049]
The address setting for the nonvolatile memory 16 can be electrically performed from the outside via the transmission control unit 12. Further, at the time of factory shipment, the set address can be directly written to the nonvolatile memory 16 using the memory writing device via the repeater MPU 13.
[0050]
In this case, since the analog fire detector 3-5 is connected to the transmission line 2 from the receiver 1 at a stage where the address is not fixed, the address of the nonvolatile memory 16 is set to the use prohibition address “255”. .
[0051]
The analog fire detector 3-4 is the same as the analog fire detector 3-5, and the transmission control unit 12 and the repeater MPU 13 provided in the analog fire detector 3-5 are connected to the repeater 3-1, 3-2 and 3-3 have the same circuit function.
[0052]
Next, the monitoring control processing of the disaster prevention monitoring system of the present invention having the functional configuration of FIG. 2 will be described with reference to the flowchart of FIG. 4 taking fire monitoring as an example.
[0053]
In FIG. 4, when the system is started up by turning on the receiver 1, the receiver 1 sends a polling command to the transmission line 2 while designating the terminal addresses in the order of addresses 1 to 254 in step S1.
[0054]
In response to the sending of the polling command, if the terminal side determines that the set address of its own matches the address of the polling command, it responds with status information indicating the current terminal status.
[0055]
The receiver 1 that has received the status information from the terminal proceeds to step S4 if it is a normal response from the status information in step 2, and performs fault handling processing in step S3 if there is a fault response in the status information. In the failure handling process, the occurrence of a failure and the terminal address where the failure has occurred are displayed on the display unit 5 of the receiver 1.
[0056]
In step S4, it is checked whether or not the received signal by the polling response is a fire interrupt. When a fire alarm is issued at a terminal that performs fire monitoring, a fire interrupt signal is sent to the transmission line 2 in a form that destroys the status information at the timing of response of the status information to the polling command.
[0057]
Therefore, the presence or absence of a fire interrupt is determined at the response timing of the status information. If there is a fire interrupt, the receiver 1 first performs an address search using the group address as the address confirmation processing in step S5.
[0058]
In the address search, for example, address numbers 1 to 254 are grouped for each predetermined number of terminals, and a fire confirmation command using a group address assigned to each group is transmitted. If the group including the fire alarm detector can be identified by the confirmation by this group address, the fire confirmation command using the terminal address in the group is output in sequence, and the terminal that made the fire alarm by receiving the fire response Check the address.
[0059]
In the fire notification of the terminal set with any one of addresses 1 to 254 effective as a system, the address confirmed in step S5 is other than the use-prohibited address “255” whose address is unknown. Then, after collecting detection information from the analog fire detector at the notification address, fire alarm processing is performed when a fire is judged from the collected analog information in step S14. When recovery is confirmed after the fire alarm, a fire recovery process is performed in step S16 based on the recovery operation of the administrator.
[0060]
On the other hand, in the analog fire detector 3-5 in FIG. 2, since the address is not fixed, the terminal address is the use prohibition address “255”. For this analog fire detector 3-5, an address setting operation is performed from the use-prohibited address “255” to a valid terminal address using a detector alarm test performed in the middle of installation work.
[0061]
For this reason, the analog fire detector 3-5 is caused to fire by using the alarm test jig 21 as shown in FIG. When the analog fire detector 3-5 fires, the repeater MPU 13 is operated by the fire detection output of the fire detection unit 15, and at the response timing of the status information of the polling command from the receiver 1 via the transmission control unit 12. A fire interrupt signal is sent in a form that destroys the status information. Therefore, a fire interrupt is determined in step S4 in FIG. 4, and an address confirmation process is performed in step S5.
[0062]
However, since the terminal address of the analog fire detector 3-5 that has been notified is the use-prohibited address “255”, this is determined in step S6, and the mode selection screen 17 as shown in FIG. 3 is displayed in step S7. The person in charge attached to the receiver 1 with respect to the display of the mode selection screen 17 selects the address setting mode selection menu 20 for address setting for the analog fire detector 3-5.
[0063]
For this reason, the selection of the address setting mode is recognized in step S9, and the process proceeds to step S11. In step S11, the terminal address table information stored in the memory of the receiver MPU 8, that is, the terminal information 1 to 254, is referred to the table information indicating whether or not the address is used, and the unused space is not used. The addresses are extracted and a list of free addresses is displayed, thereby checking the free addresses.
[0064]
Therefore, in step S11, the person in charge confirms that the address to be set for the analog fire detector 3-5 is included in the empty address list displayed on the display unit 5, and then proceeds to step S12. For example, a numeric keypad 6a provided in the operation unit 6 of the receiver 1 of FIG. 1 is operated to input a set address, and after confirming whether the input address is correct, an execution operation is performed.
[0065]
As a result, the address setting command including the address input from the receiver is sent to the analog fire detector 3-5 that has fired by the test, and the use prohibition address “255” written in the nonvolatile memory 16 is set. Rewrite to the address specified by the address setting command from the receiver 1.
[0066]
At this time, only the notified analog fire detector 3-5 with unknown address responds to the address setting processing command from the receiver, and the analog fire detector with unknown address not notified does not respond.
[0067]
On the other hand, if the analog fire detector 3-5 for which the use prohibition address “255” is set is not a test notification but is generated due to an actual fire, step S7 is performed as in the case of the test notification. Then, the mode setting screen 17 of FIG. 3 is displayed.
[0068]
At this time, if a person in charge is attached to the receiver 1, since the test issuance for address setting is not performed, it is determined that there is a possibility of fire, and the fire processing mode selection menu 19 is selected. For this reason, the selection of the fire processing mode is determined in step S8, and the process proceeds to step S14 where the same processing as the normal fire alarm is performed for the analog fire detector 3-5 in which the use prohibition address “255” is set.
[0069]
If no one is attached to the receiver 1, after the mode selection screen 17 as shown in FIG. 3 is displayed in step 7, the fire processing mode is selected in step S8, or the address setting mode in step S9. If neither of these selections is performed, the elapse of a fixed time is checked in step S10, and if a certain time elapses without selecting any mode, the process proceeds to step S14, which is the same as a normal fire alarm. Fire treatment will be performed.
[0070]
In the above embodiment, an analog fire detector is taken as an example of the terminal, and the use prohibited address “255” is set here, and the address can be set by the test report. In addition to this, the present invention can be similarly applied to address setting after a gas leak detector or other abnormality detector is connected and a use-prohibited address is set and installed in an address unconfirmed state.
[0071]
The present invention is not limited to the above-described embodiments, includes appropriate modifications without impairing the objects and advantages thereof, and is not limited by the numerical values shown in the embodiments.
[0072]
【The invention's effect】
As described above, according to the present invention, when a terminal is installed on a transmission path from a receiver, a specific use-prohibited address that is not used as a terminal address is set when the address is uncertain, When setting a valid address that has been established after installation, the terminal is tested, and the receiver recognizes that the address is unknown to this test operation, and can switch to address setting mode. Can be changed to a fixed address, and the address setting for a terminal for which a prohibited address has been set remotely from the receiver side without compromising the abnormality monitoring function as a system including a terminal whose address is not fixed. It can be done easily.
[0073]
In particular, even if the address setting mode is selected for the test notification of a terminal for which a prohibited address is set, this address setting mode is performed as one process in the fire monitoring mode, and the fire monitoring mode is canceled. Instead, even when the address setting change operation is being performed in the address setting mode, when an abnormal report is received from another terminal, a normal fire monitoring process is performed, and the abnormality monitoring function is not impaired by the address setting.
