Abstract
Description
[Technical Field]
[0001] The present invention relates to a technique that is effective when applied to a monitoring device such as a fire receiver or a fire monitoring control panel that is equipped with a standby power supply testing device that tests whether a standby power supply with a built-in battery has the desired performance. [Background technology]
[0002] Conventionally, disaster prevention monitoring systems equipped with fire receivers and fire monitoring control panels that receive detection signals from fire detectors and issue fire alerts have been provided with a backup power supply unit with a built-in secondary battery for backup in the event of a power outage, in addition to a main power supply unit that runs on commercial AC power. The secondary batteries used in the backup power supply of fire alarms are kept charged by DC voltage obtained by rectifying and smoothing commercial AC power under normal monitoring conditions, but since there is a risk that the secondary batteries will deteriorate over long periods of use and the charge capacity may become insufficient, backup power supplies are tested periodically and as needed. Backup power tests are often performed by operating a backup power test switch installed on the fire alarm.
[0003] Conventionally, while a standby power supply test switch is operated, the supply of DC power supply voltage based on a commercial AC power source is switched to the supply of DC power supply voltage based on a standby power source (battery), and a dummy load is connected to the standby power source for testing, and the standby power supply test control unit is configured to forcibly terminate the standby power supply test when a certain time has elapsed since detecting that the standby power supply test switch is turned on (Patent Document 1).
[0004] In the standby power supply testing device described in Patent Document 1, the supply of DC power voltage is switched to the standby power supply (battery) during testing. Therefore, if the test time is long, the amount of discharge increases, and the remaining battery charge becomes low after the test is completed, which may result in the device being unable to operate for more than the specified guaranteed time in the event of a power outage. Therefore, the applicant has invented and previously filed a patent application for a standby power supply testing method and monitoring device that can prevent battery deterioration from progressing due to repeated discharge tests being performed in a relatively short period of time (Patent Document 2). [Prior art documents] [Patent documents]
[0005] [Patent Document 1] Japanese Patent Application Publication No. 09-35156 [Patent Document 2] Patent Publication No. 2019-78636 Summary of the Invention [Problem to be solved by the invention]
[0006] The invention described in Patent Document 2 requires that the time required to charge the standby power supply ("required charging time") must have elapsed after recovery from a power outage or after a performance test of the standby power supply has been completed, and this prevents the battery from deteriorating further due to repeated discharge tests being conducted in a relatively short period of time. However, in reality, there are cases where the battery can be fully charged before the "required charging time" has elapsed. However, in the invention of Patent Document 2, even if the battery is fully charged, if the "required charging time" does not end, there is a problem that it is not possible to intentionally perform a performance test, such as a short-time discharge test that has almost no effect on the performance of the standby power supply and is conducted to check whether the charge / discharge switching circuit is operating normally.
[0007] Therefore, in order to determine whether the standby power supply is sufficiently charged, it is possible to repeatedly calculate the "required charging time" constantly or at short intervals. However, it has become clear that repeatedly performing calculations places a heavy load on the control device, and in the case of a fire receiver, for example, this could have an impact on the processing of fire occurrence signals from detectors, which is the device's original function.
[0008] The present invention has been made with an eye on the above-mentioned problems, and its purpose is to provide a monitoring device such as a fire receiver or a fire monitoring control panel that can check the performance of a standby power source while avoiding impairing the original functions of the device by recalculating the "required charging time" only when certain conditions are met, thereby making it possible to avoid having to wait unnecessarily for the "required charging time" to pass. [Means for solving the problem]
[0009] In order to solve the above problems, the present invention provides: A monitoring device comprising a main power supply, a standby power supply with a built-in battery, voltage measurement means for measuring the voltage of the standby power supply, and a standby power supply testing device capable of testing whether the standby power supply has desired performance by passing a predetermined current from the standby power supply to a dummy load for a predetermined time, The standby power supply testing device a required charge time calculation means for calculating a required charge time required to charge the standby power supply device each time one of a plurality of unsteady operations related to the power supply of the monitoring device occurs, based on the measured voltage of the standby power supply device at the time the unsteady operation occurs; an elapsed time measuring means for measuring the elapsed time from the end of the unsteady operation; a determination means for determining whether the elapsed time is longer than the required charging time, When a command to start a standby power supply test is input, a discharge test of the standby power supply device is carried out in response to the determination by the determination means that the elapsed time is longer than the required charging time.
[0010] With a monitoring device configured as described above, the "required charging time" is recalculated every time an unsteady operation occurs, that is, only when a predetermined condition is met. This makes it possible to check the performance of the backup power supply without impairing the device's original functions, and avoids having to wait unnecessarily for the "required charging time" to pass.
[0011] Preferably, the plurality of non-steady-state operations are a battery test of the standby power supply device, and at least one of restarting the standby power supply testing device, powering on or restoring power to the main power supply device, and connecting the standby power supply device to the standby power supply testing device. With this configuration, when the above-mentioned unsteady operation occurs, the information on the state of the standby power supply is interrupted, so the "required charging time" can be recalculated to accurately grasp the state. Furthermore, since the above-mentioned unsteady operation does not occur frequently, it does not increase the load on the control device, and in the case of a fire alarm receiver, for example, it is possible to prevent it from affecting the execution of highly urgent processing, such as processing fire signals from detectors, which is the device's original function.
[0012] Preferably, the power supply device further comprises a standby power supply connection detection means for detecting a transition from a disconnected state to a connected state of the standby power supply device, The standby power supply testing device is configured to detect the connection of the standby power supply as the non-steady operation based on information from the standby power supply connection detection means. With this configuration, because the backup power supply connection detection means is provided, the backup power supply testing device can immediately detect the connection of the backup power supply when the backup power supply changes from not being connected to being connected, and there is no need to manually input or set the backup power supply connection information into the backup power supply testing device.
[0013] Furthermore, it is preferable that the standby power supply testing device has an input means for instructing the standby power supply testing device to perform a battery test on the standby power supply. a plurality of operation buttons for instructing the display device to display information; the battery test of the standby power supply includes a first standby power supply test and a second standby power supply test having a longer discharge time than the first standby power supply test; the first standby power supply test is started in response to a battery test command input from the input means; The second standby power supply test is configured to be started in response to input of a battery test command from the input means and operation of any one of the plurality of operation buttons. According to this configuration, two standby power supply tests can be started separately using existing switch buttons.
[0014] Preferably, the device further comprises a display device, an information notification lamp for notifying that there is information to be displayed, and an operation button for issuing a command to display the information, The standby power supply testing device is configured to turn on or flash the information notification lamp when the standby power supply test is completed, and to display the results of the discharge test on the display device based on the operation of the operation button. With this configuration, the monitor can have the results of the discharge test of the standby power supply displayed on the display unit as needed, allowing the monitor to accurately grasp the state of the standby power supply device. [Effects of the Invention]
[0015] According to a monitoring device equipped with the standby power supply testing device of the present invention, the "required charging time" is recalculated only when certain conditions are met, thereby making it possible to check the performance of the standby power supply while avoiding impairing the original functions of the device, and preventing situations in which the user has to wait unnecessarily for the "required charging time" to pass.

DETAILED DESCRIPTION OF THE INVENTION
[0017] Hereinafter, an embodiment in which the present invention is applied to a fire control panel will be described with reference to the drawings. An example of the configuration of the front panel of a fire receiver according to an embodiment of the present invention is shown in Figure 1. The fire receiver 10 shown in Figure 1 is installed in a building's disaster prevention center or central control room, and has the function of receiving fire signals from sensors and transmitters installed in the building, sounding a local sound device to notify of the occurrence of a fire by sound, and also notifying of the occurrence of a fire by means of indicators such as lamps provided on the front panel of the fire receiver 10. In addition, the housing of the fire receiver 10 is provided with a main power supply unit equipped with an AC-DC converter that operates on commercial AC power to generate DC voltage, and a separate standby power supply unit for backing up in the event of a power outage.
[0018] As shown in Figure 1, the front panel of the fire receiver 10 is equipped with a main operation unit 11 that displays the operating status of the fire receiver, such as when AC power is turned on, when a fire alarm is activated, and when a transmitter signal is input, by lighting up various lamps; a district display unit 12 for the fire alarm line that displays the line where a fire alarm has been activated and the line where a detector line has been disconnected; a district display unit 13 for the smoke control line that displays the location of the fire and the location where the smoke control terminal has been activated; a speaker 14 that notifies of the occurrence of a fire, etc.; an audio operation unit 15 that has a push button for stopping the receiver's sound and bell (district sound); an information display unit 16 that consists of an LCD (liquid crystal panel) that displays information such as the receiver's operating mode and the results of the battery test described below; a display operation unit 17 that has a shift button for changing the displayed content; and an information operation unit 18 that has an information button 18a and an information lamp 18b for displaying the fire content, abnormality content, etc. of the receiver on the information display unit 16 for confirmation.
[0019] In the information operation unit 18, if there is a factor that requires the supervisor to be notified, the information lamp 18b flashes, and by pressing the information button 18a, fire information and abnormality information are displayed on the information display unit 16. In addition, an openable and closable sub-door 10a is provided at the bottom of the front panel of the fire receiver 10, and inside the sub-door 10a is provided an internal operation unit 19 having a battery test switch button 19A that commands the start of a battery test (to be described later), a fire test switch button 19B that commands the start of a fire test, a test recovery button 19C that commands recovery from a battery test, and a fire recovery button 19D that commands recovery from a fire test, etc. The test recovery button 19C is not limited to being used to issue a command to recover from a battery test, but may also be used to issue a command to recover from a detector operation test (during inspection).Similarly, the fire recovery button 19D may be used to issue a command to recover the receiver and detector from a fire condition.
[0020] The display operation unit 17 is provided with a shift button (△) for forwarding the displayed content, a shift button (▽) for reversing the displayed content, a "back" button for returning the display mode to the original, and a "decide" button 17D for deciding the display mode. Although not shown, a control board that receives command inputs from the operation units (11, 17, 18) and drives the display units (12, 13, 16) and speaker 14 is installed inside the housing of the fire control panel 10. Furthermore, a backup power supply unit that supplies power to the control boards and the like in place of the main power supply unit in the event of a commercial AC power outage, and a backup power supply testing device that tests the backup power supply unit are also installed inside the housing of the fire control panel 10.
[0021] FIG. 2 shows an example of the configuration of a backup power supply testing device provided in the fire control panel of this embodiment. As shown in Fig. 2, the standby power supply testing device in this embodiment includes a control board 20 provided within the housing of the fire control panel 10. The control board 20 is composed of a control unit 21 equipped with a CPU (microprocessor), ROM (read-only memory), and RAM (random access memory). Note that the control board 20 also receives input of signals from the aforementioned fire test switch button 19B and fire recovery button 19D, and has the function of executing processes related to fire testing, but Fig. 2 only shows the hardware related to battery testing of the standby power supply. In other words, the control board 20 functions as the standby power supply testing device.
[0022] On the control board 20, there are provided a reset button 22 for restarting the control unit 21, a power-on detection circuit 23 for detecting the start-up of the power supply and inputting a reset signal to the control unit 21, a timer 24 for measuring time, a voltage detection unit 25 for detecting the voltage of the backup power supply 32, and the like. The location of the reset button 22 is not limited to the control board 20, and it may be provided in another location, such as the internal operation unit 19 described above. Furthermore, the reset button 22 is not limited to a reset button in the strict sense, and may be any button equivalent to a reset button. Furthermore, the timer 24 may be configured by software. In addition, a power supply switching circuit 33 that switches between the main power supply and the backup power supply, and a charging and connection monitoring circuit 34 that controls battery charging and monitors whether the battery is connected or not are provided between the control board 20 and the main power supply device 31 and backup power supply device 32. These circuits may be mounted on the control board 20.
[0023] Furthermore, the control board 20 receives command signals from a battery test switch button 19A that commands the start of a battery test on the standby power supply, the information button 18a of the information operation unit 18, and the shift buttons 17A and 17B, the "back" button 17C, and the "decision" button 17D of the display operation unit 17, and the control board 20 is configured to control the display drive of the information display unit 16 and the lighting drive of the information lamp 18b in response to signals from these input means.
[0024] FIG. 3 shows an outline of a procedure of processing related to a battery test of a backup power supply by control unit 21 on control board 20 of fire control panel 10 of this embodiment. As shown in Fig. 3, the control unit 21 executes two processes in parallel: one according to the flow on the left and one according to the flow on the right. Of these, the flow on the left shows the flow for calculating the "required charging time" required to charge the battery of the standby power supply, and determines whether or not an unsteady operation has occurred and has ended. If it is determined that it has ended (Yes), the control unit 21 performs a calculation process for the "required charging time" and stores the calculation result in memory.
[0025] The flow on the right side of Figure 3 shows the flow of executing the battery test of the standby power supply, and determines whether a test start command has been input. If it is determined that the command has been input (Yes), the battery test of the standby power supply is executed. When executing this battery test of the standby power supply, the "required charging time" calculated in the flow on the left side and stored in memory is referenced. The specific steps of the battery test of the standby power supply will be explained later using Figure 5.
[0026] Fig. 4 shows a flowchart of the detailed procedure of the processing according to the flow on the left side shown in Fig. 3. The processing according to this flowchart starts when the main power supply is turned on and the power-on detection circuit 23, which detects this, inputs a reset signal to the control unit 21. Note that the power-on detection circuit 23 also detects recovery from a power outage while the main power supply device 31 is switched on (including when a standby power supply is connected), generates a reset signal, and inputs it to the control unit 21.
[0027] When a reset signal is input, the control unit 21 executes an initial setting process (step S1) that initializes specific addresses, clears flags, and performs other settings, and then reads the battery voltage of the backup power supply 32 from the voltage detection unit 25 (step S2). Based on a signal from the charging and battery connection monitoring circuit 34, the control board 20 determines whether the backup power supply 32 is connected or not, and if it is connected, calculates the time required to fully charge the battery and stores this in internal memory (RAM) (step S3). If the battery is not connected, for example, a pre-defined "backup power supply not connected" flag is set. A specific method for calculating the required charging time will be described later.
[0028] Next, the control unit 21 determines whether or not a reset signal has been input from the reset button 22 (step S4). If it determines that a reset signal has been input (Yes), the process returns to step S1 and executes the above-mentioned processes S1 to S3. On the other hand, if it determines in step S4 that a reset signal has not been input (No), the process proceeds to step S5 and executes the original process of the fire receiver, which is to monitor signals from sensors installed within the monitored area. This sensor monitoring process is not directly related to the standby power supply testing device, so a detailed explanation will be omitted. Next, the control unit 21 detects inputs from the various input buttons of the main operation unit 11 and the display operation units 17 and 18 provided on the front panel of the fire control signal receiver and executes processing accordingly (step S6). This input button detection processing is also not directly related to the standby power supply testing device, so a detailed explanation will be omitted.
[0029] Thereafter, control unit 21 proceeds to step S7, where it determines whether battery test switch button 19A provided on internal operation unit 19 has been turned on. If it determines that battery test switch button 19A has been turned on and then turned off without turning on decision switch button 17D, that is, that battery test switch button 19A has been pressed and held down (Yes), it proceeds to step S8, where it executes a short-time standby power supply test in which the battery is discharged for a short time (for example, 3 seconds). Note that this short-time standby power supply test is performed to check whether the charge / discharge switching circuit provided in standby power supply device 32 is operating normally, and therefore long-term discharge is not necessary. After the short-term standby power supply test in step S8 is completed, control unit 21 reads the battery voltage of standby power supply device 32 from voltage detection unit 25 (step S9) and determines whether it is within the normal voltage range (step S10). If it determines that the battery voltage is normal (Yes), it proceeds to step S13, calculates the time required to fully charge the battery based on the battery voltage at that time, stores this in internal memory (RAM), and returns to step S4.
[0030] On the other hand, if it is determined in step S7 that the battery test switch button 19A has not been pressed and held (No), the process proceeds to step S11, where it is determined based on the signal from the charging / battery connection monitoring circuit 34 and the aforementioned "backup power supply not connected" flag whether the backup power supply device 32 has changed from not connected to connected. If it is determined that the state has not changed to connected (No), the process returns to step S4. On the other hand, if it is determined in step S11 that the backup power supply device 32 has changed from disconnected to connected (Yes), the process proceeds to step S12, where the battery voltage of the backup power supply device 32 is read from the voltage detection unit 25, the required charging time is calculated from the read battery voltage, and the calculated time is stored in memory (step S13), and the process returns to step S4. In addition, in step S12, a process of clearing the "backup power supply not connected" flag may also be performed.
[0031] 5 shows a flowchart of one embodiment of the procedure for a 10-minute discharge test by the control board 20 of a monitoring device having a standby power supply testing device. This discharge test is performed by passing a predetermined current from the standby power supply to a dummy load for a predetermined time (e.g., 10 minutes). 5 is initiated by simultaneously pressing (turning on) battery test switch button 19A provided on internal operation unit 19 (see FIG. 1) inside sub-door 10a and decision switch button 17D provided on the front panel. Then, after the previous power outage, the system determines whether the elapsed time from when the power source was switched back from the backup power source to the main power source (when the power source was switched back) to when the current discharge test operation begins, or the elapsed time from the end of the previous discharge test to the start of the current discharge test operation, is longer than the time required to fully charge the battery in the backup power supply device calculated when the power source was restored or when the previous discharge test ended (see steps S3, S13, and S29) (step S21).
[0032] If it is determined that the time required for charging the battery has not elapsed (step S21: No), the test is not started and the process proceeds to step S30, where the information display unit 16 provided on the front panel of the fire control receiver 10 displays the fact that the time required for charging has not elapsed and the remaining time until the next 10-minute discharge test can be performed (time required for charging - time elapsed). On the other hand, if it is determined in step S21 that the time required for charging the battery has elapsed (Yes), the process proceeds to step S22, the lamp indicating "Battery Test" is turned on, a 10-minute discharge test is started, and the voltage detection unit 25 measures the voltage of the battery in the standby power supply device (step S23).
[0033] Then, it is determined whether the measured battery voltage is equal to or greater than a preset value Va (for example, 12.0 V) (step S24). If it is determined that the battery voltage is not equal to or greater than the preset value Va (No), an abnormal termination of battery charging is displayed on the information display unit 16. Furthermore, the information lamp 18b, which indicates that there is information to display, lights up or flashes to forcibly terminate charging. After that, when the information button 18a is pressed, the cause of the abnormality (termination) (in this case, a defective battery) is displayed on the information display unit 16. Also, if it is determined in step S24 that the battery voltage is equal to or greater than the predetermined value Va (Yes), the process proceeds to step S25, where the elapsed time (or remaining time) and the measured voltage are displayed on the information display unit 16 on the front panel of the fire control signal receiver 10.
[0034] Then, the process proceeds to step S26, where it is determined whether the battery test switch button 19A has been pressed (turned on). If it is determined that the test switch has been turned on (Yes), the process proceeds to step S31, where it is determined whether the measured battery voltage is equal to or greater than a predetermined value Vb (e.g., 20.4 V). If it is determined that the battery voltage is equal to or greater than the predetermined value Vb (Yes), the discharge test is forcibly terminated. Then, the information display unit 16 displays a termination status (standby power supply normal). If it is determined in step S31 that the battery voltage is not equal to or greater than the predetermined value Vb (No), the discharge test is forcibly terminated, and the information display unit 16 displays a termination status (standby power supply abnormality). Furthermore, the information lamp 18b lights up or flashes. If the information button 18a is then pressed, the cause of termination (standby power supply abnormality) is again displayed on the information display unit 16.
[0035] On the other hand, if it is determined in step S26 that the test switch is not turned on (No), the process proceeds to step S27 to determine whether 10 minutes have passed since the start of the discharge test. If it is determined that 10 minutes have not passed (No), the process returns to step S23 and the above processing (S23 to S26) is repeated. Furthermore, if it is determined in step S27 that 10 minutes have elapsed (Yes), the process proceeds to step S28, where it is determined whether the battery voltage is equal to or greater than a predetermined value Vb (e.g., 20.4 V). If it is determined that the battery voltage is not equal to or greater than the predetermined value (No), the information display unit 16 displays the end status (backup power supply abnormality). Also, the information lamp 18b lights up or flashes. Thereafter, when the information button 18a is pressed, the information display unit 16 displays the cause of the abnormality (end) (discharge test abnormality).
[0036] On the other hand, if it is determined in step S28 that the battery voltage is equal to or greater than the predetermined value Vb (e.g., 20.4 V) (Yes), the process proceeds to step S29, where the time required for full charging of the battery in the standby power supply device is calculated based on the battery voltage and stored in memory, and then the information lamp 18b is turned on or flashes, ending the discharge test. Thereafter, by pressing the information button 18a, the end status (discharge test normal) is displayed on the information display unit 16. Furthermore, by pressing the shift button on the display operation unit 17, the time required for full charging calculated in step S29 can be displayed.
[0037] In addition, the calculation of the time required to fully charge the battery in step S29 (similar to steps S3 and S13 in FIG. 4) is performed by assuming that the measured voltage at that time is Vd, the charging voltage of an undegraded battery is Vc (for example, 28.8 V), and the time required to fully charge the battery is Tc (for example, 48 hours). The time T (h) required to fully charge the battery is calculated using the following formula: T(h)=(Vc-Vd)÷(Vc-Vb) / Tc Here, if the measured voltage Vd at the end of the 10-minute discharge test is the predetermined value Vb, i.e., Vd = Vb, then from the above formula, T(h) = Tc, and the required time is 48 hours. The closer the measured voltage Vd at the end of the test is to Vc, the smaller the value of (Vc - Vd) will be, and therefore the shorter the required charging time will be. The procedure for the 10-minute discharge test has been described above, but the above procedure is an example and is not limited to this.
[0038] Although the invention made by the inventor has been specifically described above based on an embodiment, the present invention is not limited to the above embodiment. For example, in the above embodiment, the required charging time at the start of a discharge test was calculated based on the measured voltage of the backup power supply (battery), the charging voltage of an undegraded battery, and the time required for full charging at that charging voltage. However, the required charging time may also be calculated using the amount of discharge from the start of the required charging time (the end of the previous discharge test, a power outage, or full charging) to the start of the current discharge test. Specifically, an ammeter that measures the current value on the output side of the battery may be provided in the backup power supply (or control board 20), and the discharge capacity may be calculated from the product of the discharge current and the discharge time, and the required charging time may be calculated from the charging current value.
[0039] In the above embodiment, the control board having the original fire detection function based on the detector signal of the fire receiver is also provided with the function of a backup power supply testing device, but it is also possible to provide a control board having the original fire receiver function and a separate backup power supply testing control board for performing the battery test described above. In this case, the reset signal is configured to be input to both the original control board and the backup power supply testing control board. Furthermore, in the above embodiment, a connection monitoring circuit (34) is provided as a backup power supply connection detection means that detects a transition from a disconnected state to a connected state based on the voltage of the backup power supply device, but a switch that physically detects the presence or absence of a backup power supply may also be provided in the backup power supply storage section. Furthermore, in the above explanation, the standby power supply testing device of the present invention has been described as being applied to a standby power supply testing device for a fire alarm receiver, but it can also be applied to a testing device for a standby power supply installed in a monitoring device such as a fire monitoring control panel.
