The invention provides a pipeline patrol, maintenance and checking method which is applied to application program servers and comprises the following steps: receiving a patrol task instruction transmitted form a PC, generating a patrol task, and sending out the patrol task, thereby enabling patrol operators to implement patrol; receiving patrol data forwarded from a mobile terminal through a Wechat server, and storing the data in a database server; and judging patrol data types according to internal patrol data identifiers, if the patrol data is ordinary patrol data, generating an ordinary patrol operation state change signal and transmitting to the PC, and if the patrol data is abnormal event patrol data, forwarding a part of information to the PC, generating an abnormal event patrol operation state change signal according to the abnormal event patrol data, and transmitting the signal to the PC. The steps of the maintenance and checking method are similar to those of the patrol method. By adopting the pipeline patrol, maintenance and checking method provided by the invention, the problems that, in the prior art, mobile APP software development cost is high and programs are low in portability can be solved.
