The invention relates to the electronic field and discloses a monitoring method based on an intelligent part and the intelligent part and a security and protection monitoring system. The monitoring method mainly comprises that A, a server monitors at least one object to be monitored according to monitoring strategies preset by a user; B, uploaded security and protection monitoring information of the objects to be monitored is received and comprises security and protection monitoring data and power consumption of the objects to be monitored; C, the security and protection monitoring information is compared with set information in the monitoring strategies to determine whether current security and protection monitoring situations of the objects to be monitored are abnormal; D, if determined results in step C are abnormal, whether alarm information is needed to be sent to the user is determined according to the monitoring strategies; and E, the server sends the alarm information to the user if determined results in step D are needing. By means of the technical scheme, personalized security and protection monitoring strategies can be formulated by users, the security and protection monitoring range is expanded, labor costs are reduced, and housing security and protection effects are improved.
