Referring to FIG. 1 and FIG. 2 , FIG. 1 is a schematic diagram of the circuit 10 of the indicator light fixture 100 , and FIG. 2 is a schematic diagram of a housing 20 for accommodating the circuit 10 . The indicator 100 includes a circuit 10 and a housing 20, wherein the circuit 10 is provided with a light-emitting unit 110, a battery 120, a first power conversion module 130, a battery detection module 150 and a signal unit 160, wherein the battery 120 can be a lithium battery, One of the group consisting of lead-acid batteries, nickel-cadmium batteries and nickel-metal hydride batteries, but this creation is not limited to this. The light emitting unit 110 can be one or more light emitting diodes (Light Emitting Diode, LED) for illuminating the casing 20 . The casing 20 is used for accommodating the light-emitting unit 110 , the battery 120 , the first power conversion module 130 , the battery detection module 150 and the signal unit 160 , and the casing 20 preferably has a light-transmitting effect and includes a direction indicating pattern, such as The escape direction indication pattern shown in Figure 2. Although Figure 2 uses the left side as the evacuation direction as an example, this creation is not limited to this.

The first power conversion module 130 is coupled to the light-emitting unit 110 and the battery 120 and is used to convert the AC input voltage AC1 (for example, an AC voltage of 110V or 220V) into a first DC voltage DC1 (for example, a 4.2V DC voltage) . The battery detection module 150 is coupled to the first power conversion module 130 and the battery 120 , wherein the first power conversion module 130 supplies power to the battery 120 (eg, 4.2V DC voltage), and the battery detection module 150 detects the battery 120 . The battery detection module 150 includes a second power conversion module 151 , a microcontroller 152 and a seven-segment display 153 . The second power conversion module 151 is coupled to the first power conversion module 130 for converting the first DC voltage DC1 into the second DC voltage DC2 and providing the two DC voltages DC2 to the microcontroller 152 , wherein the second DC voltage DC2 is provided to the microcontroller 152 . The voltage value of the DC voltage DC2 can be designed according to the requirements of the microcontroller 152 , which is not particularly limited in the present invention. The seven-segment display 153 is coupled to the microcontroller 152 and used to display information according to the control of the microcontroller 152 , and the present invention does not limit the information.

The circuit 10 further includes a real time clock (RTC) 140 and a button battery 190 . The real-time clock 140 is coupled to the microcontroller 152, so that the microcontroller 152 has a perpetual calendar function, and sends a detection signal D1 at a predetermined time to detect the state of the battery 120, and judges whether the state of the battery 120 is abnormal according to the feedback signal R1. For example, the detection signal D1 can be issued at 12:00 noon every day, so that the inspection personnel of the factory can complete the inspection at one time. In addition, the same batch of indicators can be set to the current time according to the perpetual calendar before leaving the factory, so that multiple indicators can be detected and reported at the same time, and the inspection personnel can complete the inspection at the scheduled time. The button battery 190 is coupled to the real-time clock 140 and is used to maintain the operation of the real-time clock 140, especially the setting of the perpetual calendar before leaving the factory.

The button battery 153 is further used to maintain the operation of the microcontroller 152 and supply power to the microcontroller 152, especially to maintain the perpetual calendar settings before leaving the factory. According to a long-term design of the present invention, when the first power conversion module 130 is externally connected to a power source (not shown), the microcontroller 152 can be configured to be powered by the first power conversion module 130 instead of the button battery 190 to supply power, which can prolong the service life of the button battery 190, so it is not necessary to replace the new button battery frequently.

The signal unit 160 is coupled to the battery detection module 150 (ie, coupled to the microcontroller 152 ), and sends a warning signal according to the command C1 of the battery detection module 150 when the state of the battery 120 is abnormal. In an embodiment of the present invention, the warning signal may be a light signal with a specific color and a specific flashing frequency. For example, when the battery detection module 150 determines that the first power conversion module 130 cannot charge the battery 120 (for example, it is detected that the power of the battery 120 does not change significantly), it may be due to the abnormality of the substrate, and the signal unit 160 sends a first A signal S1; when the battery detection module 150 determines that the perpetual calendar function of the microcontroller 152 is faulty or abnormal (for example, a detection signal is sent to the microcontroller 152 but no corresponding report signal is received), the signal unit 160 sends a first The second signal S2; when the battery detection module 150 judges that the battery 120 is low or faulty, the signal unit sends a third signal S3. Wherein, the first signal S1 , the second signal S2 and the third signal S2 may have lights of different colors and/or flashing frequencies.

The microcontroller 152 can be, for example, a 32-bit microcontroller (Microcontroller, MCU) including 32 pins, but the present invention is not limited to this, as long as it can achieve similar functions or effects, it can also be replaced by other models 's microcontroller. The detailed operation of the microcontroller 152 is as follows:

(1) The microcontroller 152 has a built-in perpetual calendar, and automatically detects the battery status at 12:00 noon on the 15th of every month. If the battery power cannot keep the indicator 100 on for more than 35 minutes, the indicator of the signal unit 160 will automatically display a fault. For example, Rapid flashing of the red light (flashes every 5 milliseconds) indicates that the battery 120 is abnormal (equivalent to the third signal S3 above). However, the exact test date and fault expression can be adjusted according to the needs of the test personnel.

(2) If the fault of the battery 120 is detected, a quick test will be carried out after the battery is replaced to confirm whether it is normal. If it is normal, the fault light will be eliminated. If the quick test result shows that the battery 120 is still faulty, the signal unit 160 keeps displaying the fault light (ie, keeps displaying the third signal S3 ).

(3) Detect whether the board (such as the first power conversion module 130 ) can charge the battery 120 normally. If not, the signal unit 160 continuously displays a red light to indicate that the substrate is abnormal (equivalent to the above-mentioned first signal S1 ).

(4) Detect whether the perpetual calendar in the machine board is counting normally. If the perpetual calendar is abnormally counting, the light of the signal unit 160 will be red and flash slowly (for example, once every 1 second) (equivalent to the above-mentioned second signal S2).

(5) If there is no abnormal condition, the light of the signal unit 160 will display green to indicate normal.

The above lights of different colors can be displayed by a single LED or by different LEDs. In addition, the color and flashing frequency of the light signal of the signal unit 160 can be adjusted according to the needs of the user, and the above is only an example, and is not particularly limited.

The hazardous event is, for example, but not limited to, a fire event.

Please refer to FIG. 4 . FIG. 4 is a schematic diagram of an indicator lamp 400 according to another embodiment of the invention. As shown in FIG. 4 , the indicator 400 further includes a detection button 180 . The detection button 180 is coupled to the battery detection module 150 (ie, coupled to the microcontroller 152 ), for the detection personnel to trigger the microcomputer by manually pressing The controller 152 detects the battery 120 or other abnormal states (such as the failure of charging the board or the incorrect counting of the perpetual calendar). When the state is abnormal, the battery detection module 150 will send a command to the signal unit 160, so that the signal unit 160 sends the first signal S1, the second signal S2 or the third signal S3. In this embodiment, a manual detection mechanism is additionally provided to complete the detection even when the microcontroller 152 fails, or to provide the detection personnel to perform manual detection during the unscheduled period.

Please refer to FIG. 5. FIG. 5 is a schematic diagram of an indicator 500 according to another embodiment of the creation. As shown in FIG. 5 , the indicator 500 further includes a speaker 170 and a detection button 180 , so that the functions of the above two embodiments can be realized at the same time. Since the functions and operation methods of the speaker 170 and the detection button 180 have been introduced, no further explanation is given.

In conclusion, the present invention can improve the accuracy and immediacy of fault reporting of the indicator light without causing side effects, so as to improve the efficiency of the maintenance of the indicator light by the factory personnel. Through the design of the built-in perpetual calendar of the indicator, the indicator can measure and report the battery on time and at the predetermined time. The maintenance and inspection personnel of the factory only need to patrol within the predetermined time range (such as but not limited to the daily predetermined time). A plurality of indicator lights, when the indicator lights emit a warning signal, it means that the battery of the indicator lights is abnormal or the storage power is insufficient. In this way, the burden of maintenance and inspection personnel to patrol the indicator light fixtures will be greatly reduced, and the safety of the working environment can also be ensured. Compared with the prior art, which required 15 workers to inspect 3,000 direction indicator lamps and 1,000 emergency lighting lamps in the factory for 8 hours each, this creation only requires one worker to inspect for 1 hour, which is less likely to happen. omission.
