The present invention relates to a fire receiver.

2. Description of the Related Art Conventionally, a storage unit is provided inside a disaster prevention receiver, in which a database, event information (history list), and the like are stored, and a device using a memory card or the like as the storage unit is known. (For example, refer to Patent Document 1).
JP 2005-032025 A

  In the above conventional example, the memory card is detached after the fire receiver is turned off.

  FIG. 5 is a flowchart showing an operation of attaching and detaching a memory card in a conventional fire receiver.

  In S21, the fire receiver is set in a monitoring state. To remove the memory card, the fire receiver is turned off in S22, and the memory card is removed in S23. In S24, data is added to or changed from the removed memory card using a rewriting device (such as a personal computer). When the addition or change of the data is completed, the memory card is attached to the fire receiver in S25, and the power of the fire receiver is turned on in S26, whereby the fire receiver returns to the monitoring state (S27).

  In the above operation, after the power of the fire receiver is turned off (S22), the fire receiver is in a fire non-monitoring state during the time of power on (S26).

  As described above, the power of the fire receiver is turned off when the memory card is attached / detached. If the fire receiver is in the ON state, there is a possibility that the memory card is reading / writing data. This is because if the memory card is inserted or removed while reading / writing data from / to the card, the data will be damaged and this data destruction will be prevented.

  However, when the power of the fire receiver is turned off when the memory card is inserted or removed, the monitoring control of the facility is stopped, and a so-called unmonitored state is entered.

  In addition, when data such as a history list is stored in the memory card, it is necessary to remove the memory card once in order to retrieve the stored data. While it is on, turn off the fire receiver.

  Therefore, in the above conventional example, the power supply of the fire receiver is turned off every time the memory card is attached / detached, so there is a problem that the monitoring control of the facility is stopped and so-called unmonitored states increase.

The present invention enables the fire receiver to maintain the monitoring state when the memory card is removed from the fire receiver, and the memory card can be safely removed even while the fire receiver is operating. It aims at providing the fire receiver which can escape.

The present invention uses a fire receiver that reads predetermined information from a memory card storing predetermined information or writes predetermined information to the memory card when the memory card is attached to the fire receiver. A slot, an input means for inputting the attachment / detachment state of the memory card with respect to the fire receiver, and a write operation and reading with respect to the memory card in accordance with the state of the input means with the fire receiver turned on. A fire receiver having control means for stopping at least one of the operations.

According to the present invention, when the memory card is removed from the fire receiver, the fire receiver can maintain the monitoring state, and the memory card can be safely removed even while the fire receiver is operating. There is an effect that it is possible to escape.

  The best mode for carrying out the invention is the following examples.

  The PSU board 10 is a board that supplies a DC voltage, DC24V generated from an AC 100V by an AC / DC converter as an AC / DC power supply AC / DC, to each of the boards 10, 20, and B3 to Bn, and an OPO board. B1 is a substrate that controls transfer to the OPIN substrate B2.

  The OPO substrate B1 is an output substrate. The OPIN substrate B2 is an input substrate. The OPPS boards B3 and B4 are boards for supplying power to terminals, and are boards that supply power to terminals (for example, the district bell BL) connected to the secondary side of the repeaters C1 to C8. The NIU board B5 is a host connection board, and is a board connected to the display system DP1 via a host transmission line.

  The MCU board 20 is a board for the main control unit, is a board for the display unit and the main processing, is inserted and connected to the memory card MC1, and is provided with a dip switch SW1 and a slot SL1.

  The dip switch SW1 is an example of an input unit, and is a switch that indicates whether the memory card MC1 is attached to or detached from the fire receiver RE1. Note that ON of the dip switch SW1 indicates that the memory card MC1 has been removed from the fire receiver RE1. Conversely, OFF of the dip switch SW1 indicates that the memory card MC1 is attached to the fire receiver RE1.

  The slot SL1 is a slot for inserting and removing the memory card MC1.

  The memory card MC1 is a memory card that stores event information as a database or a history list, and is composed of, for example, a compact flash (registered trademark) card.

  That is, the MCU board 20 is an example of a control unit that stops at least one of the writing operation and the reading operation with respect to the memory card according to the state of the input unit while the power of the fire receiver is turned on. is there. The input means is means for inputting a memory card attachment / detachment state with respect to the fire receiver.

  The inverter INV1 controls the power source that drives the backlight of the LCD 30. The CTU boards B6 to Bn are transmission boards connected to the terminals, and control transmission lines for two systems.

  Next, the operation of the first embodiment will be described.

  FIG. 3 is a flowchart illustrating the operation of the first embodiment.

  In S1, the fire receiver RE1 is in a monitoring state. Here, in order to take out the memory card MC1 from the fire receiver RE1, in S2, the operator turns on the dip switch SW1 in the MCU board 20 provided in the fire receiver RE1.

  Then, in S3, the fire receiver RE1 displays on the screen (LCD 30) that the memory card MC1 has been removed from the fire receiver RE1. Thereafter, in S4, the operator removes the memory card MC1 from the fire receiver RE1.

  In S5, the operator uses a rewriting device (not shown) such as a personal computer to add or change database data to the removed memory card MC1. Note that event information or the like may be taken out from the memory card MC1. Thereafter, in S6, the operator inserts the memory card MC1 into the slot SL1 of the fire receiver RE1.

  Then, in S7, the operator turns off the dip switch SW1 in the fire receiver RE1. Then, in S8, the fire receiver RE1 erases the display indicating that the memory card MC1 has been removed from the screen (LCD 30). In S9, the fire receiver RE1 reads the data of the added or changed database stored in the memory card MC1 and writes it in the RAM (not shown) of the MCU board 20, thereby adding the corresponding database. In addition, data such as event information that is stored in a RAM (not shown) and that is generated while the memory card MC1 is not inserted (removed) is written in the memory card MC1. In S10, the fire receiver RE1 continues the monitoring state.

  The memory card MC1 is a readable / writable memory, but a read-only memory (ROM) may be used instead of the memory card MC1.

  Further, during normal operation, the MCU board 20 (control unit) accesses the memory card MC1 as necessary.

  That is, in the above embodiment, when the memory card MC1 is removed, the dip switch SW1 is manually operated to stop the access to the memory card MC1 by the MCU board 20, and the memory card MC1 is removed from the fire receiver RE1. Is displayed on the LCD 30, and the memory card MC1 is removed from the slot SL1. On the other hand, when the memory card MC1 is attached to the fire receiver RE1, the memory card MC1 is inserted into the slot SL1 and the dip switch SW1 is returned. The MCU board 20 recognizes that the memory card MC1 is attached to the fire receiver RE1, erases the display of “detachment of the memory card MC1” from the LCD 30, and accesses the memory card MC1 as necessary. .

  When the database is stored in the memory card MC1, when the MCU board 20 recognizes the installation of the memory card MC1 based on the DIP switch SW1, the database stored in the memory card MC12 is read and the internal memory (RAM, FIG. (Not shown). In this way, the database is updated and monitoring control as a normal operation is performed.

  FIG. 4 is a flowchart showing an operation of monitoring the attachment / detachment of the memory card MC1 in the fire receiver RE1.

  In S11, monitoring of whether the dip switch SW1 is ON or OFF is started. If it is determined in S12 that the dip switch SW1 is OFF, the normal monitoring state is maintained in S13. If the dip switch SW1 is switched from ON to OFF in S14, the memory card MC1 is inserted. Therefore, the setting (database) addition / change data is read from the memory card MC1 and written to the RAM (not shown), and stored in the RAM (not shown) while the memory card MC1 is not installed in S15. The generated event information and the like are written.

  On the other hand, if it is determined in S12 that the dip switch SW1 is ON, in S16, the withdrawal of the memory card MC1 is displayed on the LCD 30, access (read / write) is stopped, and abnormal sound is emitted from the speaker SP1.

  The memory card MC1 is a memory for storing at least one of, for example, the predicted replacement date of a predetermined part and the predicted replacement date of a predetermined device, in addition to database data and a received history list.

  According to the above embodiment, by turning on the dip switch SW1 provided in the fire alarm facility FA1, the memory card MC1 can be removed without turning off the power of the fire receiver RE1.

  Further, according to the above embodiment, when the setting of the database or the like in the memory card MC1 is changed, when the memory card MC1 is attached to the fire receiver RE1 and the dip switch SW1 is turned off, the setting in the memory card MC1 is changed. The operation of reading and writing to RAM (not shown) is automatically executed. Thus, since the fire receiver RE1 is in a fire monitoring state even while the memory card MC1 is removed and data is added or changed, safety is high.

  In the above-described embodiment, ON of the dip switch SW1 indicates that the memory card MC1 has been removed from the fire receiver RE1, and OFF of the dip switch SW1 indicates that the memory card MC1 is attached to the fire receiver RE1. This may be reversed, but may be reversed. That is, ON of the dip switch SW1 indicates that the memory card MC1 is attached to the fire receiver RE1, and OFF of the dip switch SW1 indicates that the memory card MC1 has been removed from the fire receiver RE1. It may be.

  Further, in place of the dip switch SW1 in the above embodiment, a panel surface indicating means for indicating the attachment / detachment state of the memory card MC1, for example, a touch panel TP of the LCD 30, is provided on the panel surface, and the MCU board 20 is responsive to an instruction from the panel surface indicating means. Alternatively, at least one of the writing operation and the reading operation with respect to the memory card MC1 may be stopped while the fire receiver RE1 is kept on.

That is, the dip switch and the panel surface instructing means are examples of input means for inputting the attachment / detachment state of the memory card MC1 with respect to the fire receiver RE1.
