The invention provides a user power utilization information collection and meter reading device and method based on a Beidou satellite communication system. The device comprises a server, a Beidou central computer, a Beidou client and a concentrator, wherein the Beidou central computer is communicated with the Beidou client through the Beidou satellite communication system; the server is connected with the Beidou central computer; the concentrator is connected with the Beidou client; and the Beidou central computer and the Beidou client are used for caching a measurement calling instruction and user power utilization information respectively so as to realize secondary caching of the measurement calling instruction and the user power utilization information. The user power utilization information collection and meter reading device and method can be used for reliably and rapidly obtaining the user power utilization information of regions with undeveloped communication by using a Beidou satellite.
