The periodic test system comprises an upper computer system and a lower computer system. Database in the upper computer system are managed, so that data required by tests can be provided; each channel test comprises at least one test, each test corresponds to a function module, the corresponding function modules are called when the channel tests are executed, then the data which correspond to the function modules and are required by the tests are called from the databases and are transmitted to the lower computer system via networks, and instructions for executing the function modules are transmitted to the lower computer system; the lower computer system comprises test items corresponding to the function modules of the channel tests, and the corresponding test items are executed when the instructions transmitted by the upper computer system are received by the lower computer system.

The invention provides a periodic test device for a pressurized water reactor nuclear power plant protection system, which comprises a real-time control system, and a computer in network connection with the real-time control system for executing a human-computer interaction function. The real-time control system is an embedded controller and comprises a central processor and multiple synchronous data communication channels, and the real-time control system is connected with a tested channel of the protection system via the synchronous data communication channels. When the test is executed, the computer provides a test signal and issues a test instruction, and the real-time control system injects the test signal to the tested channel of the protection system via the synchronous data communication channels, executes the test instruction issued by the computer, acquires a test result, and feeds the test result back to the computer. The test device also comprises a self-inspection and annual inspection device which periodically executes self-inspection on the real-time control system and annual inspection on precision verification of analog input and output channels.

The invention relates to an infrared communication decoding method of an embedded system. The infrared communication decoding method consists of an integrated infrared receiving head and an embedded terminal which requires an infrared communication function. A microprocessor is provided with an infrared waveform data structure body which comprises a Timer_Count, a pIR_Wave, an IsIR_Wave, a cache regionIR_Wave and the like; an interrupt service and an application service are adopted to form a two-stage processing method; a timer 0 is started when in the interrupt service of a GPIO (General Purpose Input Output), and the application service is activated by conditions when in the interrupt service of the timer 0; a task of analyzing and decoding collected infrared waveform data is completed through the processing of the application service. The infrared communication decoding method has the beneficial effects that the acquisition, decoding and analysis of infrared waveforms are independently completed, so that the high efficiency of infrared decoding of the microprocessor is improved, and the universality of the microprocessor to different codes is also improved.

A structure layout parameter determination method of an agile satellite comprises two parts of solar panel layout parameter optimization and star sensor layout parameter optimization. An optimization goal of the solar panel layout parameter optimization is set as an energy generation value of each track of a solar panel, bounded variables of the optimization goal are track parameters, attitude parameters and solar panel effective charging conditions, and variable parameters are solar panel installation angles. Optimal values of the solar panel installation angles are determined by mathematical solution. An optimization goal of the star sensor layout parameter optimization is set as a star sensor available time period, bounded variables of the optimization goal are track parameters and attitude parameters, and variable parameters are star sensor installation angles. The star sensor installation angles are iteratively computed by mathematical solution, and an available time period optimal value of each track of a star sensor can be obtained. The structure layout parameter determination method can maximumly improve application effectiveness of the agile satellite under the premise of satisfaction of a working mode of the agile satellite and a satellite mission application mode.

The invention discloses a crushing pick for municipal roads, being able to generate extensible cracks by means of internal expansion. The crushing pick structure comprises a body, a generator, an on-off switch, a handle, a pick head and a diameter-enlarging crushing device, and has the advantages that through the anti-splashing mechanism and the pick head counter-rotating action, the part of scattered stones produced when the pick head collides with the pavement are bounced from the four sides, unnecessary damage to the face of the operator in the first place can be avoided; at the same time,under the action of the thread lines arranged on the surface of the vertebral body of the barrier, the stones at the bottom of the road are quickly rubbed by the external force in the reverse direction to change from the stone slab with cracks to the broken stones; by using the mutual cooperation of the ejector bar and the pattern cam, cracking of the rock blocks in the bottom of the road is accelerated, and the cracks of the rock blocks in the bottom of the road are extended by using the triangular vertebrae of different sizes, and the crushing area is enlarged, and the crushing of the upperstone slab is easier by enlarging the crushing cracks of the stone slab in the bottom of the road; and the crushing of the rock blocks in the upper stone slab can be well carried out when the holes onthe sides are cut, and the time effectiveness of the road crushing is improved.
