Description

  The present invention relates to an improvement in a fire receiver that monitors a plurality of sensors and rings a district acoustic terminal when a fire occurs.

  Systems using fire receivers as described above are installed in buildings such as condominiums and general commercial buildings. However, in recent years, renewal of buildings is also popular, and fire receivers are used as they are. There is a request to add or remove. However, since the number of detectors connected to the fire receiver is enormous and there are several types of detectors, registering the detector information in the fire receiver is a difficult task. .

  Prior art relating to sensor registration is described in, for example, the following Patent Document 1. According to it, the fire receiver incorporates a terminal processing unit in which individual data is registered in advance, and when registering a sensor, the individual disaster prevention terminal connected by reading the individual data from the terminal processing unit It is set as the structure which controls.

Japanese Unexamined Patent Publication No. 08-016969

  However, in the configuration as in the cited document 1, in order to change the configuration of the terminal (increase / decrease in the number of sensors, etc.), it is necessary to replace the terminal processing unit, which requires a corresponding part cost. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a fire receiver having a novel configuration in which the addition of sensors and the like can be easily performed without replacement of parts.

  The fire receiver according to the present invention has a sensor table in which sensor information including valid / invalid state is registered together with address information for each sensor, and sensor information including valid state is registered in the sensor table. When the effective change operation is performed on the line control unit that monitors and controls only the detected sensor and the desired sensor information registered in the sensor table, the sensor information is changed to the valid state. And a table setting unit having a function of updating the sensor table.

  The fire receiver may further include a table setting auxiliary unit that detects and displays a sensor connected to a sensor line from sensors in which sensor information including an invalid state is set. .

  In addition, when an invalid change operation is performed on desired sensor information registered in the sensor table, the table setting unit changes the sensor information to an invalid state and updates the sensor table. It may further have a function.

  Further, the table setting unit may further have a function of deleting the sensor information from the sensor table when a deletion operation is performed on desired sensor information registered in the sensor table. .

  The sensor information may further include sensor type information.

  According to the present invention, at the time of construction, all sensors to be finally connected are registered in the sensor table, and only a part thereof is connected to the fire receiver, and the remaining sensors are added later. Can be easily done. And no part replacement is required for the expansion. Therefore, after the building is completed, it becomes possible to build the system step by step at a low cost according to the usage situation.

1 is a basic block diagram of a fire receiving system according to the present invention. Is an example of a sensor table. Is an example of an operation screen for adding sensors. Is an example of an operation screen for pausing the sensor. Is an example of an operation screen for deleting sensor information.

  The receiver 1 shown in FIG. 1 is installed in a building such as an apartment or a general commercial building. The receiver 1 is generally classified into P-type first grade, P-type second grade, and R-type, but the present invention can be suitably implemented especially for the R-type.

  In the system using the R-type receiver, a unique address is assigned to each sensor 2, and signal transmission in which those addresses are designated is performed between the receiver 1 and the sensor 2. The signal transmission may be polling in which the receiver 1 transmits a command signal designating an address and the sensor 2 of the address returns a response signal.

  The receiver 1 includes, as basic components, a line control unit 13 that controls the sensor 2, the district acoustic terminal 6, the fire door 7, the smoke prevention device 8, the watering device 9, and the like, an operation unit 15, and a district display. A unit 16, a liquid crystal display unit 17, an audio unit 18, a transfer unit 19, and a CPU substrate 20 are provided. Further, as an element according to the present invention, a sensor table 11 in which sensor information such as an address and a type is registered for each sensor 2, and an input operation of the sensor information is received and set in the sensor table 11. And a table setting unit 12.

  Since the sensor table 11 is a part that stores important setting items, it is preferable that the sensor table 11 is composed of a non-volatile storage element such as a flash memory or the memory element is backed up by a battery.

  The receiver 1 detects the sensor connected to the sensor line 31 from the sensors 2A in which sensor information including an invalid state is set, and detects sensor information of the sensor 2A. May be further provided with a table setting auxiliary unit 14 for displaying a list of items.

  The receiver 1 is connected to a sensor line 31 to which the sensor 2 is connected, an acoustic line 32 to which the district acoustic terminal 6 is connected, a fire door 7, a smoke prevention device 8, a watering device 9, and the like. The control line 33 is derived.

  The sensor line 31 is wired to the sensor 2 arranged in each room via the isolator 3 arranged for each floor. The sensor line 31 is also connected to a transmitter 4 that notifies a fire by operation and is terminated by a terminator 5. In this example, the residential building is divided into districts 001 to 004 for each room, and serial numbers of addresses 01 to 12 are assigned to the sensor 2. The address assignment operation may be performed using a jig such as an address setting device.

  In this example, the sensor 2 is assumed to be a photoelectric analog type (smoke type), but is not limited to a specific type, and may be a thermal type or a flame type.

  The isolator 3 is provided for a short-circuit accident that occurs downstream of the sensor line 31. When the downstream line is short-circuited from the isolator 3, the downstream line is separated from the upstream line so that the entire line functions. Prevent stopping.

  Next, the basic operation of the system to which the present invention is applied will be described.

  When the sensor 2 starts accumulating, the receiver 1 turns on the accumulating lamp. When the accumulation of the sensor 2 continues for a predetermined time or longer, the receiver 1 issues a fire. When the sensor 2 is restored during accumulation, the receiver 1 turns off the accumulation lamp and returns to the monitoring state.

  When the receiver 1 is in a fire alarm state, the main sound is emitted from the audio unit 18 and the “site confirmation”, “fire”, “building, floor, district”, etc. of the occurrence location are displayed on the district display unit 16. . At this time, a detailed alarm screen may be displayed on the liquid crystal display unit 17 and the alarm content may be printed out.

  The main sound is, for example, a message such as “Peep, the sensor has been activated. Please check the site”. The restored sensor 2 may re-activate within a predetermined time, but after the second time, the message may be different, such as “Peep, fire, fire. Please check the scene”. .

  Further, the receiver 1 rings the district acoustic terminal 6 according to preset interlocking registration and operates devices such as the fire door 7, the smoke proof device 8, and the watering device 9. Conditions such as which device to activate should be set individually for each level of attention, alerting, and interlocking. For example, at the attention level, only the district audio terminal 6 near the occurrence site is ringed. Moreover, it is good also as a structure which raises an interlocking | linkage level in steps according to elapsed time, ie, increases the apparatus to operate in steps.

  In response to such a notification operation, the administrator operates the sound stop switch to temporarily stop the interlocking of the district sound terminal 6 and the like, confirms the site, and if it is a fire, operates the fire determination switch. , Restart the linkage of the district audio terminal 6 and the like. Note that devices such as the fire door 7, the smoke proof device 8, and the water spray device 9 can be manually controlled by a control operation switch. After the fire is extinguished, the receiver 1 is returned to the monitoring state by the recovery switch. On the other hand, if it is not a fire, the receiver 1 is returned to the monitoring state by operating the recovery switch after taking measures such as removing the operating factor of the sensor 2.

  Next, features of the present invention such as registration change of sensor information will be described.

  The main purpose of the present invention is to facilitate the expansion and removal of the sensor 2. Therefore, the sensor information including the valid / invalid state of the sensor 2 is registered in the sensor table 11 by the table setting unit 12, and the line control unit 13 detects the sensor information in which the sensor information including the valid state is registered. Only the device 2 is to be monitored and controlled.

  FIG. 2 shows an example of the sensor table 11, and sensor information for one device is stored in each storage slot. The sensor information includes, for example, setting information for one sensor such as address, valid / invalid state type, district, attention accumulation level, alarm accumulation level, linked accumulation level, message, and linked equipment. However, when it is installed in an apartment house composed of a plurality of buildings, it may further include information such as buildings and floors. If a specific symbol such as “*” is input as the type, it may be regarded as an invalid state. By doing so, the capacity of the sensor table 11 can be saved.

  The valid / invalid state in the sensor information is important information for determining whether or not the sensors 2 and 2A are to be monitored and controlled. Specifically, the sensor 2 in the valid state is connected to the sensor line 31 and is the object of monitoring and control, but the sensor 2A in the invalid state is the object of monitoring and control. Excluded from. That is, even if the sensor 2A in which sensor information including an invalid state is registered is connected to the sensor line 31, it does not affect the operation of the receiver 1 at all. In other words, such a sensor 2A does not participate in fire detection and does not perform failure diagnosis. Therefore, even if the sensor 2A is removed from the sensor line 31, no failure or error notification occurs. In FIG. 1, the sensor 2 </ b> A indicates a sensor that is in an invalid state, and a common reference symbol is used both when connected to the sensor line 31 and when not connected. .

  According to the present invention, the table setting unit 12 has the following function for changing the sensor information.

  That is, the table setting unit 12 extracts and displays a list of sensor information including invalid states from the sensor table 11 as a screen for selecting sensor information to be changed, or sensor information including valid states. Are extracted and displayed in a list. In this list display, the displayed sensor information may be narrowed down. For example, a ridge, a floor, and a district may be specified, and only sensor information of the sensor 2 corresponding to those conditions may be displayed. When an effective change operation is performed with the sensor information selected for a list display of sensor information including an invalid state, the sensor information is changed to the valid state and the sensor table 11 is updated. Such an operation can be executed even when the receiver 1 is in a monitoring state. Further, when the contents of the sensor information changed to the valid state by this operation and the sensor 2A to be added do not match, for example, when the type is different, it is desirable to report an error.

  With such a configuration, at the time of construction, as shown in FIG. 1, only a part of the sensor 2 to be finally connected to the sensor line 31 is installed, and the remaining sensors will be installed later. A step-by-step system construction such as adding 2A (the amount that was not initially installed) can be easily implemented. And no part replacement is required.

  Specifically, if the sensor information of all the sensors 2 and 2A (including those not connected at that time) is registered in the sensor table 11 at the time of construction, an address is set in the later expansion work. It is only necessary to connect the detected sensor 2A to the sensor line 31 and update the corresponding sensor information. In particular, in the configuration provided with the table setting auxiliary unit 14 as described above, work such as examining the entire sensor table 11 is unnecessary, so that the labor is greatly reduced particularly in the case of a large-scale system. Is very prominent.

  FIG. 3 is an example of an operation screen for adding the sensor 2A to the sensor line 31. Sensor information of the sensor 2A to be added is registered in the sensor table 11 in advance. However, the sensor information includes an invalid state.

  When a predetermined operation is performed, the receiver 1 displays such an operation screen on the liquid crystal display unit 17. In this example, the sensor 2A to which the address 03 is assigned is detected, and the sensor information is displayed. Since it is assumed that there is one sensor 2A to be added here, only one sensor information is displayed. However, if there are a plurality of sensors 2A to be added, the sensor information is listed. Is displayed.

  The liquid crystal display unit 17 is configured by a touch panel, and operation keys such as “screen printing”, “end”, “individual addition”, “add all”, “execute”, and the like are arranged. Here, the “screen print” key is an operation key for printing out the display screen, and the “end” key is an operation key for stopping the addition of the sensor 2A. The “Individual Add” key is an operation key for confirming the selected sensor information from the displayed sensor information, and the “Add all” key is an operation target for all displayed sensor information. As an operation key. The “execute” key is an operation key for executing a process of updating the sensor table 11 by changing the sensor information determined as the operation target to the valid state.

  On this operation screen, if the “individual registration” key is operated to select the sensor information at the address 03 and then the “execute” key is further operated, the sensor table 11 is updated. It becomes the object of monitoring and control.

  Further, as a modification of the present invention, when an invalid change operation is performed on desired sensor information registered in the sensor table 11, the table setting unit 12 changes the sensor information to an invalid state and performs detection. A function of updating the container table 11 may be provided. This is a function for excluding a specific sensor from the object of monitoring and control, and therefore it may be executed before removing the specific sensor 2 from the sensor line 31.

  FIG. 4 is an example of an operation screen for removing the sensor 2 from the sensor line 31.

  On the operation screen, sensor information including valid states is displayed in a list in the sensor table 11, and operation keys such as “screen print”, “end”, “individual pause”, “all pause”, and “execute” are also provided. It is arranged. “Screen printing” and “end” are the same as described above. The “Individual Pause” key is an operation key for confirming the selected displayed sensor information as an operation target, and the “Register All” key is an operation key for confirming all displayed sensor information as an operation target. It is. The “execute” key is an operation key for executing a process of updating the sensor table 11 by changing the sensor information determined as the operation target to an invalid state.

  In this operation screen, after selecting the sensor information at address 04, if the “individual pause” key is operated and the “execute” key is further operated, the sensor table 11 is updated. Excluded from monitoring and control. Therefore, after this operation, the receiver 1 can be removed from the sensor line 31 while the receiver 1 remains in the monitoring state.

  Note that another configuration for changing the sensor information to an invalid state is also conceivable. For example, if the receiver 1 is in a monitoring state, an error is notified when the sensor 2 to be disabled is removed from the sensing device line 31. At this time, the sensor information of the sensor 2 is disabled by a predetermined operation. To change the sensor table to update the sensor table. Alternatively, the sensor information of the sensor 2 informed of the error may be displayed as a list, and specific sensor information may be selected from the list display. In this way, since the number of sensor information displayed in a list is limited, selection becomes easy.

  Further, as a modification, the table setting unit 12 may have a function of deleting the sensor information from the sensor table when the desired sensor information registered in the sensor table 11 is deleted. . This is a function for deleting the sensor information itself of the sensor 2A removed from the sensor line 31.

  FIG. 5 is an example of an operation screen for deleting sensor information from the sensor table 11.

  The operation screen displays a list of sensor information including invalid states in the sensor table 11, and includes operation keys such as “screen print”, “end”, “individual delete”, “delete all”, “execute”, and the like. It is arranged. “Screen printing” and “end” are the same as described above. The “individual deletion” key is an operation key for confirming selected sensor information as an operation target, and the “register all” key is an operation key for confirming all displayed sensor information as an operation target. The “execute” key is an operation key for executing a process of deleting sensor information determined as an operation target from the sensor table 11.

  If the sensor information at address 06 is selected on this operation screen and then the “individual delete” key is operated and the “execute” key is further operated, the sensor information is deleted and the sensor table 11 is updated. Such a process may be executed when the specific sensor 2A becomes permanently unnecessary due to renewal or the like. As a result, there is a margin in the sensor table 11, and it becomes easy to install another sensor 2 in another location.
