Kaifeng Weiye uses Lon Bus control bus to realize network communication. In order to ensure the stability and reliability of network communication, its communication protocol meets the control requirements of each layer of the seven layers of the International Standards organization's Open System Reference Model (ISO/OSI). The core of system control network technology is a neuron chip with three CPUs, which embeds and solidifies the first six layers of the reference model of the network Lon Talk communication protocol into the neuron chip to ensure reliable communication of the network.

According to the different power supply methods of the lamp battery, the composition of the centralized control type fire emergency lighting and evacuation indication system can be divided into two different ways: when the battery (power supply) of the lamp adopts the centralized power supply method, the system is composed of the emergency lighting controller, emergency lighting centralized power supply, centralized power control type fire emergency lighting and system components (see Figure 1). When the battery (power supply) of the lighting fixtures adopts an independent built-in battery power supply method, the system is composed of emergency lighting controllers, centralized control of the built-in power supply for fire emergency lighting fixtures, emergency lighting distribution boxes, and other system components (see Figure 2).
