Embodiment Construction

[0013] In order to obtain the running information of the train system in real time and dynamically, without updating the software, it can comprehensively obtain various resource information and the running status of the program. The full name of the UDP protocol is the User Datagram Protocol, which is used for processing in the same way as the TCP protocol in the network. UDP packets are a connectionless protocol. In the OSI model, in the fourth layer (transport layer), it is the upper layer of the IP protocol. UDP has the disadvantages of not providing data packet grouping, assembling and sorting of data packets, that is to say, after the message is sent, it is impossible to know whether it has arrived safely and completely. UDP is used to support network applications that need to transfer data between computers.

[0014] The XML language (Extensible Markup Language, Extensible Markup Language) is a set of rules for defining semantic tags, which divide documents into many p...

Abstract

The invention discloses a method combined with XML description for hardware automated testing. The method includes the following steps that information of all registers of a CPU is described through XMLs; data are analyzed through an upper computer and a lower computer in the same format on the basis of a UDP; all the registers of the CPU are grouped according to functions, each group comprises registers of different lengths and numbers, and the registers have different definitions and purposes. The method can be applied to a commonly used client / server system and used for obtaining various resources, messages and the like of the opposite side; time cost is saved, steps of repeated modification, compiling and downloading of procedures are avoided, time for system testing is greatly saved, and complexity is reduced; information expressed in a list mode is converted into a tree structure to be expressed, so open-and-shut understandings can be established for internal relations of data.

Description

technical field [0001] The invention belongs to the field of software testing, and specifically refers to a method for acquiring, setting and automatically diagnosing and testing hardware resource information of a safety CPU applied in an industrial control system and a safety signal system. Background technique [0002] In industrial control systems and safety signal systems (applied to avionics, railway signal, nuclear power and other industries), it is very important to obtain the operation information of the program dynamically in real time, and prevent problems before they happen based on the obtained information. [0003] Based on the existing technology, it is not possible to dynamically acquire information in VxWorks (the VxWorks operating system is an embedded real-time operating system (RTOS) designed and developed by Wind River Corporation of the United States in 1983, which is a key component of the embedded development environment). Easy thing, this generally re...
