The invention belongs to the field of machining, and particularly relates to a lathe fixture of polygonal parts, which is used for processing clamping and location of parts with a quite high requirement on form and location tolerance. At present, when parts with externally square and precise inner hole characteristics are processed through a lathe, an operator is required to put the parts on the lathe, the parts are clamped through a four-jaw chuck, and precise holes of the parts can be processed after the operator continuously and manually adjusts the parts for alignment; and the method has the defects that firstly, the location precision of the four-jaw chuck of the lathe is not high, and the alignment is hard to achieve; and secondly, the repetitive location precision is not high, and the form and location tolerance between the precise inner holes and shape of the parts is hard to guarantee. The invention provides a locating fixture which is quick in clamping, automatic in location, quick and convenient to use, low in labor strength, high in working efficiency, and safe to operate, and is used for processing parts which have externally square and precise inner hole characteristics and have a relatively high requirement on the form and location tolerance between the precise inner holes and shape of the parts.

The invention relates to a two-way tire pressure monitoring system device. The system includes a receiving controller and several tire pressure sensors, and is characterized in that the receiving controller includes a built-in LF transmitter, and is designed to monitor each tire pressure sensor by means of two sets of IDs. For one-to-one or one-to-many communication, the tire pressure sensor works in a passive state, and the receiving controller sends commands through the LF transmitter to trigger the function operation of the tire pressure sensor. The invention greatly reduces the manufacturing and installation costs of the prior art device, and can realize all the functions of the prior art, including the tire pressure sensor's instant wake-up, sleep, and automatic positioning, and the tire pressure sensor has lower energy consumption, monitoring Strategies can be dynamically adjusted according to operating conditions, improving monitoring and safety.

The invention provides a method and system for locating a continuous integration failed case and solves the problem of low manual location efficiency at present. The method comprises the following steps: filling a journal output byte code in an engineering code when loading the engineering code; recording a method invoking journal through the journal output byte code before each method of starting a test script when operating the test scrip including the engineering code, and forming an journal file of a method invoking hierarchy according to the method invoking journal; and analyzing a test script which is failed to operate according to the method invoking hierarchy in the journal file, and locating the reason of failed operation. According to the method and system for locating the continuous integration failed case, disclosed by the invention, codes are not needed to be manually debugged so that the problem reason can be conveniently, quickly and automatically located, the problem is saved, the maintenance is convenient, a large amount of time and energy is saved and the working efficiency is improved.
