The invention discloses a picture document processing method and device. The picture document processing method comprises the following steps: preprocessing a picture document to acquire a connected-domain based page image; segmenting the connected-domain based page image into one or a plurality of picture blocks; determining the types of the picture blocks according to the document content attribute of the picture blocks; correspondingly rearranging any one or more types of picture blocks according to the size of a displaying area to acquire the display data of each type of picture block; and displaying the display data of the picture block in the displaying area. Due to the adoption of the picture document processing method and device, the layout can be rearranged directly on the image layer of the picture document without using a reading tool, the reading efficiency is improved, the conversion error caused by using the reading tool to convert is avoided, and the development cost is lowered.

The invention discloses a registration mechanism-based multi-point temperature measurement control system. An ARM (Advanced RISC Machine) chip is taken as a processing core, a temperature sensor ID registration mechanism is introduced through communication with an upper computer, and when sensor nodes are replaced and added or deleted, only sensor IDs need to be operated in the upper computer or a registration circuit. The multi-point temperature measurement control system can register or deregister the sensor IDs in the upper computer or the registration circuit according to users' demands to control number of temperature measurement points so as to reasonably utilize resources; and meanwhile, sensors can be timely and quickly replaced in the presence of faults, added or deleted through the registration mechanism without program re-curing, so that great conveniences are provided for practical system maintenance and management.
