The invention provides a cooling tower monitoring method, cooling tower monitoring equipment and a cooling tower monitoring system. The cooling tower monitoring method comprises the following steps: receiving job parameter values transmitted by a collector; according to the received job parameter values and a normal value range of each job parameter in a plurality of preset job parameters, determining whether abnormal job parameter values exist in the job parameter values; if a plurality of abnormal job parameter values exist in the job parameter values, according to the abnormal job parameter values and mapping relationships between preset job parameter types and job processing users, determining the job processing user matched with each abnormal job parameter value respectively; in allusion to each determined job processing user, according to at least one abnormal job parameter value matched with the job processing user, determining a job task associated with the job processing user, and pushing the determined job task to the job processing user. The invention further discloses the corresponding cooling tower monitoring equipment and the corresponding cooling tower monitoring system.
