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.
