This invention belongs to the technical field of switch quantity acquisition devices, specifically relating to a switch quantity acquisition and synthesis device. The invention includes an embedded monitoring host, which establishes a bidirectional data connection with the switch quantity acquisition and synthesis module through a main communication module; the embedded monitoring host receives and parses the switch signals acquired by the switch quantity acquisition and synthesis module in real time; the embedded monitoring host is connected to a display module, which dynamically displays the open / closed status and alarm status of each switch; the embedded monitoring host transmits switch fault signals to a lower-level monitoring host through the main communication module; and a data processing unit, with a built-in analog-to-digital conversion circuit and protocol conversion chip, is connected to the embedded monitoring host through the main communication module. This invention features a simple structure, convenient wiring, high integration, high reliability, good scalability, and low cost.
