A mechanical energy-based self-powering counting system is provided. The system includes an electromagnetic power generator, a count measuring circuit, a count energy supply circuit, a controller and a wireless transmission module. The electromagnetic power generator is driven by an external device and produces an electric signal and outputs the electric signal to the controller after passing it through the count measuring circuit. The controller processes the received signal, updates a count according to certain programming rules and sends data to the wireless transmission module. The energy from the electromagnetic power generator flowing through the count measuring circuit can supply power to the controller. An energy storage module in the count energy supply circuit performs voltage feedback on the controller. The controller monitors the voltage of the energy storage module to control whether it enters a charging state.

A method for interconversion between protocols, including the following steps: pre-establishing a publication/subscription list; when a packet published by a publisher is received, searching the publication/subscription list for a protocol type of the packet; extracting a packet data payload from the packet; determining whether a size of the packet data payload is less than a preset combination threshold; if yes, sending the packet data payload to a packet data payload queue of the publisher, and combining a packet data payload in the packet data payload queue when a size of the packet data payload queue reaches a preset transmission threshold or no new packet is received after a preset waiting duration; searching the publication/subscription list for all subscribers corresponding to the publisher; and performing protocol conversion on the packet one by one based on protocol types used by the corresponding subscribers, and sending protocol-converted packets to the corresponding subscribers.
