The invention discloses a multi-channel telemetered data double-unit cooperative acquisition method. The method comprises the steps that a double-unit server receives water resource information data acquired by a telemetric station, wherein the double-unit server comprises a unit A and a unit B; heartbeat connection is established between the unit A and unit B; after the telemetered data is acquired, the unit A firstly writes the data into a memory database and then writes the data into a commercial database; the time for the unit B to write the data into the commercial database is delayed by a certain time compared with the time for the unit A to write the data into the commercial database, and the unit B firstly inquires the acquired data in the memory database, wherein if the data already exists, the data is discarded, and if the data does not exist, then the data is written into the commercial database after the delayed time arrives. Meanwhile, a telemetering mechanism with time slices and signal light detection and an automatic configuration update method are adopted, the reliability of the system is improved, and the data acquisition efficiency is improved.
