Abstract

The invention discloses an automatic feeder device with a remote application upgrading function. The automatic feeder device comprises a CPU (central processing unit), wherein an erasable internal Flash memory is arranged in the CPU, the outside of the CPU is connected with an Ethernet port chip which is connected with a background main station through the Ethernet to receive the latest application sent by the background main station; the internal Flash memory comprises a first memory zone, a second memory zone, a third memory zone and a fourth memory zone, the first memory zone is used for storing a boot program of the automatic feeder device, the fourth memory zone is used for storing a memory mark of the current application, one of the second memory zone and the third memory zone is used for storing the current application, and the other is used for storing historical applications. With the adoption of the automatic feeder device, the upgrading cost of the applications is greatly reduced, and potential safety accidents in the application upgrading process are effectively prevented.

Description

technical field [0001] The invention belongs to the field of power distribution, power feeding or power generation monitoring and protection, in particular refers to the remote upgrade of the program of the feeder terminal device, and specifically relates to an automatic feeder device with the function of remote upgrade of the application program. Background technique [0002] The feeder terminal unit (FTU) is an important device in the medium and low voltage distribution network automation system. It can monitor the operation status of the switch in real time, and send remote signaling and telemetry information to the master station to realize real-time monitoring and fault identification of the distribution network. , to provide decision-making basis for distribution network fault isolation, network reconfiguration, etc., so as to ensure the healthy and reliable operation of the distribution network. The FTU is used in conjunction with the switch body on the pole, and is i...
