The invention relates to an interlocking system lower computer running state detection method based on parameter tracking. An interlocking system comprises an interlocking lower computer IPS, an interlocking operation machine MMI and an interlocking maintaining console SDM. The detection method comprises the following steps that first, the SDM sends a message requesting parameter tracking to the IPS; second, the IPS receives the parameter tracking request message of the SDM, parameter values of corresponding running states are obtained according to parameters needing to be tracked, and the parameter values are sent to the SDM; third, when the SDM receives the parameter values sent by the IPS, the parameter values and parameter names are dynamically displayed on corresponding SDM interfaces. Compared with the prior art, the method has the advantages that the maintaining efficiency of field workers is effectively improved, and the workers can dynamically know the running states in the interlocking system well. |
