This utility model provides a multi-point temperature acquisition
system and a
data center cabinet. The
system includes multiple temperature acquisition modules, connecting cables, and a
concentrator. The connecting cables are two-wire systems, including a power supply line and a communication line. The multiple temperature acquisition modules and the
concentrator are connected via the connecting cables in a free topology. Each temperature acquisition module includes an address allocation
chip. Through the
system of this embodiment, the temperature acquisition modules and the
concentrator are connected in a free topology, eliminating the need for a separate cable for each temperature acquisition module or multiple folding of the wiring. This saves on the amount of wiring used in multi-point temperature detection and solves the problem of high wiring consumption in temperature acquisition.
