This is a kind of programmable control module based on the singlechip. It comprises a printed circuit board, shell body, and the leading feet. There weld and equip the singlechip, the restoration circuit, the data storage circuit, the A / D circuit, the D / A circuit, the coupling input isolation driving circuit, the coupling output isolation driving circuit, the second serial communication circuit. The printed circuit board is sealed in the shell body. Several metal leading feet of the leading feet are welded in the printed circuit board and extended out of the shell body. The module software are programmed in the trapeziform figure wise, so that the user just need to weld the programmable module on his / her designed printed circuit board. There assembled simple electronic organ around the periphery to complete the hardware design. The module adopts the trapeziform figure software programming. It's very convenient to be exploit for users. Besides it has a lower cost, a small volume and is agile to use.

The invention discloses a framework for the equipment and its sending method of message. In each frame, set a main switchboard and a standby switchboard. Each main processing board and operational plate connects to the main switchboard and standby switchboard respectively in the frame. Machine frames are connected each other through the cascade interface provided by the main switchboard and the standby switchboard. Since the invention uses a switchboard for connecting the various circuit boards, and switchboard directly provides cascade interface between frames, so the wiring between frames isgreatly simplified, which is easy to install and maintenance.

A data processing arrangement (MPS) comprises a plurality of data processors (SPR, PM1, . . . , PM4) that can be reset individually. A reset module (RSM) handles various reset request signals (HRG, SRG, SRP1, . . . , SRP4) in accordance with a prioritization and timing scheme so as to obtain respective reset signals (GRS, PRS1, . . . , PRS4) for respective data processors (SPR, PM1, . . . , PM4). The reset module (RSM) preferably comprises a reset request register, which stores respective reset requests that the respective reset request signals convey, and a request execute register, which stores respective granted reset requests that the reset signals convey.

The invention discloses a device for automatically tracking the sun on water, which belongs to the technical field of solar cells. rod, the second electric push rod, the third electric push rod, the fourth electric push rod, the fifth electric push rod, the sixth electric push rod, the seventh electric push rod and the eighth electric push rod. There are 4 fixed seats, which solve the technical problem of light tracking of solar panels on the water surface. The invention greatly simplifies the software design of the light tracking system by segmentally controlling the motion stroke of the electric push rod, and reduces two The workload of the second development, the present invention will not produce reaction force, will not drive the floating body to reverse rotation, suitable for use on the water surface, the light tracking system of the present invention has fast action speed, small action range, and little influence on the floating body on the water surface , which is conducive to the stable operation of solar panels.
