The present invention provides a general calibration system of an automobile electronic control unit and a realizing method thereof, which relates to the field of automobile electronic control. Based on configuration technique, the present invention adopts the idea that interface design is separated from system function design. The calibration system is divided into an editing environment part, an XML (extensive makeup language) configuration project file and a running environment part. The XML configuration project file is used as the middle layer of the calibration system for describing the graphical interface of the whole calibration system with a standard tree-like structure. The editing environment part is used for building a user interface model, making a calibration system interface and producing relative XML configuration project file. An XML file analyzer, data management and kernel communication are encapsulated in the running environment. The running environment part is connected with an electronic control unit (ECU) below, and monitoring and calibration functions are realized. The present invention realizes the interface customer making and reconfiguration of the calibration system, and meets the alteration and updating project requirements of the ECU. Meanwhile, the expandable and cross-platform XML project file can be reused on different operating system platforms, and the general utilization of the calibration system is improved.

The invention discloses a method and a device for modifying the log level. The method includes: receiving an http request sent by a web browser to modify the log level of the java log framework log4j, wherein the http request includes parameter information after log level modification; parsing out the log level modification from the http request After the parameter information; call the log4j interface, the log level of the log4j is dynamically modified according to the modified parameter information of the log level; output the log4j log according to the modified log level. The technical scheme of the present invention can dynamically modify the log level of log4j by sending an http request, without restarting the java application system or service, so that the maintenance personnel can immediately check the information of the log level, which is convenient for locating system problems; after the maintenance personnel find the problem, they can Change the log level to advanced in time to reduce the amount of log output, reduce resource consumption, and shorten the time cost of operation and maintenance.

The invention discloses a personal code managing tool and method under an open cloud platform. The tool comprises a third-party authorization logging-in module, a managing tool designing and developing module, a data information encryption and decryption module and a user data cloud storage module to carry out development and implementation. When the development managing tool is used, due to the fact that the development managing tool is operated on the open cloud platform, the development procedures can be simplified, development cost and management cost can be saved, and the managing tool is stably operated. When a user uses the managing tool developed based on the method, multiple equipment terminals can be maintained and managed in real time, the managing tool has good cross-platform performance, meanwhile, the personal code managing tool does not need independent account logging-in, the tool cannot record or store the information for managing the personal account and the code of the user, the danger of disclosure of the information is reduced to a certain extent, and the safety of the information is improved.

The method comprises: using bitstream-based message designing approach to divide a message into both message head and message body parts; using the object oriented design ideal to pack said message; said designed message comprising a MessageHead and a Messagebody; said message is packet into one message packet.

The invention provides a pressure test device and method for an instant communication system. The pressure test device and method are used for really and accurately testing pressure of a tested server side. The device comprises an on-line and heartbeat module, a sending end module, a receiving end module, a log system module and a log analysis module. The on-line and heartbeat module is used for sending on-line and heartbeat information of a set number of users to the tested server side of the instant communication system. The sending end module is used for simulating the users to send instant information to the tested server side according to set testing conditions after all the set number of users get online. The receiving end module is used for simulating the online users to return confirmation information to the tested server side after the users receive the instant information, and recording log information corresponding to the current instant information. The log system module is used for storing the log information in the process of testing the pressure. The log analysis module is used for evaluating the performance of the tested server side according to the log information stored in the log system module. In this way, the truthfulness of simulating the users can be improved, and then the performance of the tested server side can be evaluated more accurately.
