The invention discloses a self-monitoring process guarding method. The dispatching service, the resource allocation service and all applications of each intelligent terminal are automatically started and stopped, and the maintenance workload and difficulty are simplified to the lowest. According to a self-monitoring process guarding program, guarding tasks can be executed in respective channels without being interfered, and it is ensured that the guarded service program can continuously operate, and can be restarted in time when having problems. The program to be monitored can be automatically updated, and when the system finds that new updating packets are issued, the existing program can be automatically stopped, and the system is started after a new program is issued.
