The invention discloses a safety failure grade testing method based on a fault insertion platform. The safety failure grade testing method comprises the following steps that firstly, a testing platform is used for testing possible diagnosis situations of a product, and diagnosis information of the product is obtained in a fault insertion mode; the testing platform is used for obtaining conclusions, analysis of failure modes, diagnosis and influences is conducted through a software tool, and four failure rate values of function safety are obtained; the categories of failures of corresponding elements in the product / a system are obtained, the conclusions can be recorded by an input screen through an inside microcomputer of the testing platform, and an embedded analysis module is called for calculation. The failure rate values of the four failure modes of the function safety are obtained according to definitions in the function safety, estimation of safety failure grades is completed through combination of the testing platform and the software analysis tool, the method is simple, operation is convenient, and work efficiency is improved.
Description
technical field [0001] The invention belongs to the technical field of safety control systems, and in particular relates to a safety failure score testing method based on a fault insertion platform. Background technique [0002] With the national emphasis on the safety of petrochemical, chemical, electric power and other enterprises and the relevant policies issued by the provincial safety supervision bureaus, in 2010, the output value of the safety control system reached more than 1.5 billion yuan. According to the forecast of relevant consulting companies, in the 10 years after 2011, the compound annual growth rate of China's SIS market will reach 20%. Correspondingly, the safety control system evaluation and certification market will also have great development. It is estimated that the annual domestic market size will reach about 20 million. However, due to the lag of evaluation and certification, the control systems used in my country's nuclear power, petroleum, chemic...
