Offline variable monitoring system and method for MPUs of an EMU train

The present invention relates to an offline variable monitoring system and method for MPUs of an EMU train, comprising a serial port unit, an Ethernet interface, a TF card interface and a status indicator, which are all electrically connected to a main control unit; the main control unit is connected to a PC and TF expansion card via the Ethernet interface and the TF card interface separately, and records monitored offline variable values into the TF expansion card. The monitoring method comprised three operating modes: a configuration mode, a working mode and a download mode, which realize the monitoring of offline variables by using a multithread operating system including a TCP/IP communication thread, a main control thread and a serial port data monitoring thread. The way of recording the monitored data may be configured flexibly; and the monitoring of four central control units MPUs of the EMU train may be realized.

Crop straw decomposition agent and application method thereof

The invention discloses a crop straw decomposition agent. The crop straw decomposition agent is composed of the following components by mass percent: 20%-30% of bacillus subtilis, 20%-30% of aspergillus niger, 10%-15% of candida utilis, 15%-20% of trichoderma viride, 10%-15% of aspergillus oryzae and 1%-2% of cellulase. In order to solve the problems such that current straws are directly returned to fields, and the temperature rise is slow, the decomposition is slow and the decomposition effect is poor when the straws are used for composting an organic fertilizer, crop straw decomposition is tested for a plurality of years, microorganism strains and biological enzyme preparations are continuously screened, and finally, the bacillus subtilis, the aspergillus niger, the candida utilis, the trichoderma viride, the aspergillus oryzae and the cellulase are prepared into the crop straw decomposition agent according to the scheme. The four fungi are not antagonistic and combined with the cellulase ...
