Problems solved by technology

The data in the application data area of ​​the traditional MVB device is directly updated and upgraded through the download cable. The programming is too slow, which is not conducive to mass production, and the MVB devices in the subway train are all packaged in the system, which is troublesome to disassemble. And the system only reserves the Ethernet port as an external interface, so a method for updating and maintaining the MVB devices in the system through Ethernet is needed

Embodiment Construction

[0030] The specific embodiments of the present invention will be described in detail below in combination with the summary of the invention and the accompanying drawings.

[0031] (1) Get online MVB device

[0032] The process of obtaining the online MVB device is as follows: First, obtain the initialization of the online MVB device information, including initializing the socket, clearing the device list, and obtaining the IP of the master controller. If there is no master controller in the current passenger information system, it will fail to exit; then , send the search online MVB device command to the main control Controller, the main control Controller will return the basic information of all online MVB devices, including the chassis name, device address, and device name, analyze the data returned by the main control Controller according to the protocol, and display the online MVB device; finally, the MVB device to be processed is screened through the matching of the onlin...

Abstract

The invention provides an updating maintenance method for a passenger information system MVB device, and belongs to the field of embedded computers. The method solves a disadvantage that a MVB device on a passenger information system cannot be directly maintained and updated through an Ethernet. The method can realize functions of obtaining an on-line MVB device, reading MVB device parameters, writing MVB device parameters, and updating the MVB device by using the Ethernet. An on-line MVB device obtaining module is mainly responsible for retrieving the on-line MVB device in a system and displaying the MVB device, so as to ensure integrity and effectiveness of the MVB device before maintenance updating. A MVB device parameter reading module mainly completes functions of reading and displaying data of a parameter region. A MVB device parameter writing module mainly writes a hardware version number, a barcode number, a maintenance version number, and a production date on the parameter region. A MVB device updating module mainly completes to update an application data region of the MVB device.

Description

technical field [0001] The invention belongs to the field of embedded computers and relates to a method for updating and maintaining MVB equipment of a passenger information system. Background technique [0002] With the development of rail transit and the advancement of science and technology, the subway, as a convenient and fast mode of transportation, is becoming more and more popular among people. Passenger Information System (PIS), as the only information release, broadcast control and information management platform that directly interacts with passengers on the subway, has received more and more attention. Passenger information system consists of three subsystems: PA (Passenger Announcement), PIDS (Passenger Information Display System), and CCTV (Close Circuit TeleVision). PA consists of Controller, DACU (Driver Audio Communication Unit), PECU (Passenger Emergency Communication Unit), I / O Module (Input / Output Module), ANM (Ambient Noise Monitoring), PACU (Passenger C...
