Automated testing of emergency lights
The subject disclosure relates to power failure simulations, for example to test lighting systems, such as emergency lighting units or lighted signage. In some aspects, a method of the disclosed technology includes steps for receiving an interrupt command, terminating power delivery from a first power supply to a lighting array in response to the interrupt command, and measuring one or more power characteristics of the second power supply. Methods and machine-readable media are also provided.
1. A system for simulating power failure, comprising:
an interrupt relay coupled between a first power supply and a lighting array;
a power monitoring module coupled to a second power supply wherein the second power supply is configured to provide power to the lighting array if power supplied by the first power supply is interrupted;
a wireless transceiver configured for transacting data with a wireless backhaul gateway; and
a microcontroller coupled to the power monitoring module, the interrupt relay, and the wireless transceiver, wherein the microcontroller is configured to perform operations for:
receiving an interrupt command wherein the interrupt command is locally generated based on a predetermined testing schedule or wherein the interrupt command is received from a management system;
terminating power delivery from the first power supply to the lighting array in response to the interrupt command; and
measuring one or more power characteristics of the second power supply.
2. The system of claim 1 , wherein the microcontroller is further configured to perform operations comprising:
transmitting data comprising the one or more power characteristics to the management system via the wireless transceiver.
3. The system of claim 1 , wherein measuring the one or more power characteristics of the second power supply further comprises:
measuring one or more voltage characteristics of the second power supply.
4. The system of claim 1 , wherein measuring the one or more power characteristics of the second power supply further comprises:
measuring one or more current characteristics of the second power supply.
5. The system of claim 1 , wherein the second power supply comprises one or more battery storage cells.
6. A method for remotely managing a lighting system, the method comprising:
receiving an interrupt command at the lighting system wherein the interrupt command is locally generated based on a predetermined testing schedule or wherein the interrupt command is received from a management system;
terminating power delivery from a first power supply to a lighting array of the lighting system in response to the interrupt command; and
measuring one or more power characteristics of a second power supply that is configured to deliver power to the lighting array if power delivery from the first power supply is interrupted.
7. The method of claim 6 , further comprising:
transmitting data comprising the one or more power characteristics to the management system.
8. The method of claim 6 , further comprising:
measuring one or more voltage characteristics of the second power supply.
9. The method of claim 6 , further comprising:
measuring one or more current characteristics of the second power supply.
10. The method of claim 6 , wherein the second power supply comprises one or more battery storage cells.
11. A non-transitory computer-readable storage medium comprising instructions stored therein, which when executed by one or more processors, cause the processors to perform operations comprising:
receiving an interrupt command at a lighting system, wherein the interrupt command is locally generated based on a predetermined testing schedule or wherein the interrupt command is received from a management system;
terminating power delivery from a first power supply to a lighting array of the lighting system in response to the interrupt command; and
measuring one or more power characteristics of a second power supply that is configured to deliver power to the lighting array if power delivery from the first power supply is interrupted.
12. The non-transitory computer-readable storage medium of claim 11 , further comprising:
transmitting data comprising the one or more power characteristics to the management system.
13. The non-transitory computer-readable storage medium of claim 11 , further comprising:
measuring one or more voltage characteristics of the second power supply.
14. The non-transitory computer-readable storage medium of claim 11 , further comprising:
measuring one or more current characteristics of the second power supply.
