Infrastructure article system for synchronizing blinks of infrastructure articles connected in mesh network

An infrastructure article (101) for synchronizing blinks in a mesh network, comprising:

• a real time clock (RTC) (101) to count a sync timer;
• a wireless transceiver (103);
• at least one solar cells (104);
• a battery (105) connected to the at least one solar cells (104) and the wireless transceiver;
• at least one light source (106) connected to the battery (105);
• and
• a synchronization controller (107), connected to the at least one light source (106), configured to:
• detect an expiry of the sync timer counted by the RTC (102);
• determine whether a charge level of the battery (105) of the infrastructure article (101) meets a battery charge threshold;
• and
• perform both of:
• in response to determining that the charge level of the battery of the infrastructure article (101) meets the battery charge threshold, establish a connection with at least one of other infrastructure article and infrastructure article server (200) in the mesh network, and send a time to synchronize blink of the at least one light source (106) to all other nodes in the mesh network;
• and
• in response to determining that the charge level of the battery (105) of the infrastructure article (101) does not meets the battery charge threshold, reset the sync timer and initiate a count of the sync timer by the RTC (102).
