Method for achieving judgment on machine pump running state and interlocking through relevant parameters

The invention discloses a method for achieving judgment on a machine pump running state and interlocking through relevant parameters. The method comprises the following steps that 1, a change value range of technological parameters of all secondary machine pumps going to break down under normal changes is summarized; 2, one technological parameter or multiple technological parameters are selected to serve as the relevant parameters, the change value range of the relevant parameters under the normal changes is recorded, and an expert database is formed; 3, by means of comparison, a warning single is output to a display screen by means of a distributed control system platform and an RS trigger achieving reset priority; 4, the distributed control system (DCS) platform conducts interlocking on related equipment. According the method, on the basis of existing technological parameters, judgment is conducted on a working state of a running secondary machine pump, warning is conducted on failure of the machine pumps
