Embodiment Construction

[0043] The application system proposed by the present invention consists of two different communication networks: Ethernet and CAN network, and three different types of equipment, including PC upper computer, energy storage power main control equipment, and all other types of control equipment. Its network topology diagram is shown in figure 1 , where all other types of control equipment refer to other equipment in the energy storage power supply except the main control equipment, which are represented by class I control equipment and class II control equipment. The number after the control equipment is the equipment number, and the same type of control equipment The program files that need to be updated are the same.

[0044] In the solution of the present invention, it is proposed to use the main control device as a transfer station for online updates of all devices, and the main control device is responsible for the sending and monitoring of program update files in multiple...

Abstract

The invention discloses a method and a system for synchronously updating programs of multiple control devices in a multi-level network of an energy storage power supply. Through the Ethernet, multiple devices of various control devices on the internal CAN network of the energy storage power supply are updated synchronously. The invention can shorten the program update time, has high reliability and simple update steps, and solves the need to stop the program update of the control equipment in the current energy storage power supply, dismantle the equipment, take a long time, need to be connected to the equipment download interface, and need a pair One update, the problem of not being able to use the Ethernet interface for external communication.

Description

technical field [0001] The invention relates to the field of rail traffic control systems, in particular to a method and system for synchronously updating programs of multi-level network multi-control devices of an energy storage power supply. Background technique [0002] In rail transit, the energy storage power supply is an energy storage device composed of supercapacitors connected in series and parallel. There are a large number of various control devices with the same functions inside the energy storage power supply. These control devices use the same hardware and the same software program, only mark their positions through different switch positions, and are connected to the same control CAN network middle. In the energy storage power supply, there is also a master control device whose function is to simultaneously connect and control the CAN network and the external Ethernet, and its Ethernet interface is an external communication interface. [0003] In the existin...
