In addition, many distribution network terminal devices belong to sampling devices with low power consumption, low cost and small data volume, and transmission based on a User Datagram Protocol (UDP) is small and compact, so that many distribution network terminal devices are suitable for collecting terminal data by using the UDP.
The existing power distribution Network terminal data acquisition technology based on UDP is to directly connect an application service module with power distribution Network terminal equipment, because the power distribution Network terminal equipment is an internal Network Address of a power distribution Network, the application service module can only identify a public Network Address, and the application service module and the power distribution Network terminal equipment are not interacted, the application service module cannot directly access the power distribution Network terminal equipment, therefore, the internal Network Address of the power distribution Network terminal equipment needs to be converted into the public Network Address through NAT (Network Address Translation), and the application service module can only access the power distribution Network terminal equipment. The specific conversion method comprises the steps that the application service module receives an intranet address of data information of the power distribution network terminal equipment, the intranet address is converted into a public network address through NAT software of the application service module, and then the application service module accesses the converted public network address.
