The information paperless and automatic management can be realized, unnecessary resource waste is saved, and unnecessary personnel expenses are saved.
When the emergency lighting controller provided by the embodiment is used, reasonable linkage operation programming logic is firstly arranged on site, for example, controllers of other factories are arranged in a building 1, 101 rooms, the point position of the controller of the manufacturer is arranged in the emergency lighting controller, meanwhile, the emergency starting logic relation of on-site fire alarm is arranged, and when other control fire alarm information occurs, the emergency lighting controller can light fire emergency lighting/marking lamps in a logic relation area, so that personnel in the area can be guided to escape quickly according to a specified escape route.
Programming of the linkage logic relationship is performed in the linkage programming menu, example Y (00101×301 03) = (01001111 002) _1+ (01001×003) _2.
Formula analysis: the right side of the '=' number is a linkage condition 1 and a linkage condition 2, each condition is respectively provided with a fire alarm controller address-loop-alarm device address and an alarm device type for triggering an alarm condition, and the number at the back is the number of the needed alarm devices; the three digits after the secondary code of the lamp on the left of the "=" number and the three digits after the secondary code in the piece alarm condition on the right of the number can be the wildcard '. Smallclothes' number, which represents that the other 5 digits are the same except the digits, namely the triggering alarm condition is reached.
When the triggering alarm condition is a contact fire alarm of the controller, the type of the alarm equipment defaults to 300; while the alarm controller address defaults to 000; loop 01 represents passive, 02 represents active; the alarm address may be 001 or 002.
The corresponding contact fire conditions are described as follows:
(00001001 300) - - - - -, represents: no. 1 passive contact
(00001002 300) - - - - -, represents: no. 2 passive contact
(00002001 300) - - - - -, represents: active contact number 1
(00002002 300) - - - - -, represents: active contact number 2
When the triggering alarm condition is a contact fire of the non-controller (outside plant), the type of the alarm equipment defaults to 200; while the alarm controller address defaults to 001; loop 01 represents passive, 02 represents active; the alarm address may be 001 or 002.

(00101001 200) - - - - -, represents: no. 1 passive contact
(00101002 200) - - - - -, represents: no. 2 passive contact
(00102001 200) - - - - -, represents: active contact number 1
(00102002 200) - - - - -, represents: active contact number 2
In the emergency lighting controller provided in this embodiment, the standby power supply is connected to the standby power supply voltage detection circuit. As shown in fig. 2, the standby power voltage detection circuit uses an NPN triode and a PNP triode as switches with standby power detection function, when the standby power is not required to be detected, the main control MCU controls the BTV-EN enable pin to be turned off, so that no current flows through the resistor in the detection circuit, when the standby power is required to be detected, the main control MCU controls the BTV-EN enable pin to be turned on, and immediately controls the BTV-EN enable pin to be turned off after the complete battery voltage is detected.
The working process of the standby power supply voltage detection circuit is as follows: when the battery voltage needs to be detected, the main control MCU1 sets a high level by controlling a BTV-EN enabling pin, at the moment, the base electrode of the NPN triode T10 is high level, the emitter electrode is connected with a GND low level, the collector electrode and the emitter electrode of the triode are completely conducted, meanwhile, the collector electrode of the NPN triode T10 is connected with the base electrode of the PNP triode T11, at the moment, the base electrode of the PNP triode is low level, the emitter electrode is connected with a standby voltage BT12V-1 to be in high level, according to the characteristics of the PNP triode, the base electrode voltage is lower than the emitter electrode voltage, and the emitter electrode and the collector electrode are completely conducted; at this time, current can flow to GND through the voltage dividing resistors R9 and R11, and according to the working principle of the voltage dividing resistors, BTV-T= (R11/R9+R11). BT12V-1 can calculate real-time standby voltage; according to i=u/R, in the present circuit, i=bt 12V-1/(r9+r11), if the standby power detection enabling circuit is not added, the standby power detection enabling circuit always has current flowing through R9 and R11 and always has power loss, so that by adding the standby power detection enabling circuit, unnecessary power loss in the circuit can be prevented, and the system can work for a longer period of time more stably.
In addition, a resistor R10 and a capacitor C2 are added in the standby power supply voltage detection circuit to form an RC filter circuit, so that the linearity stability of the BTV-T detection voltage is ensured. The standby power supply voltage detection circuit is also provided with a clamping diode D3 for realizing the clamping function, the positive electrode of the clamping diode D3 is connected with 3.3V, the negative electrode of the clamping diode D3 is connected with BTV-T, according to the unidirectional conductivity of the diode, when the circuit is in an unstable state, the voltage of the BTV-T is suddenly changed, when the voltage of the BTV-T is higher than 3.3V+0.7V, the D3 diode is conducted, and current flows from the BTV-T to 3.3V, so that the safety of a BTV-T detection IO port of an MCU is protected, and the stable operation of the standby power supply detection circuit is ensured.
