However, with the popularization of the LED energy-saving lighting network system, users have diversified demands for service functions provided by the system in terms of networks. For example, in an energy-saving LED lighting system networked through a 2.4GHz band ZigBee network, a computer in a management computer room wants to manage and control a working mode of the lighting system through a local wired ethernet, a background server in a cloud terminal wants to monitor energy consumption of the lighting system through a 4G LTE network, and a user administrator wants to randomly spot check whether working parameters of LED lamps in the lighting system are normal by accessing the network through a mobile phone of the user in a Wi-Fi or bluetooth manner during routine inspection. In such a heterogeneous network, the data information in different network types must be processed and forwarded by the present invention device, so as to meet the complex application requirements proposed by users.
