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.

The utility model discloses a kind of adjustable arrangement device for electric bicycle fire experiment sensor, belong to fire safety testing equipment field.The device includes ground fixed assembly, detachable top frame and sensor positioning assembly, adopt tenon-and-mortise structure connection, realize quick assembly and disassembly by modularization design, through square steel, rectangular connecting piece and "U" steel sheet sleeve nesting form spacing accurate sensor positioning matrix, without bolt, rivet or other fastener can complete quick disassembly, and electric bicycle can be freely placed in device below.The device solves the problem that sensor point arrangement is random and inaccurate, sensor height is fixed, and sensor fixed support is inconvenient to disassemble in existing electric bicycle fire experiment, and is suitable for multi-scene electric bicycle fire parameter acquisition.
