摘要： PURPOSE:To prevent a linked tripping of the whole plant at the time of occurrence of a trouble anywhere in a generating plant, which has two or more boilers, turbines and generator machines and feeds a varying amount of power, by furnishing an emergency working device separate from the controller of conventional type. CONSTITUTION:This emergency working device is composed of an expected load calculator 5 to put out the regular load upon receiving an emergency input signal 4 from the plant 2, a turbine load and air bleeding calculating/setting device 8 to set a target value for the turbine output and the amount of bled air, and load selecting and shutoff setting device 9 to set the shutoff of the air bleeding and electric load in accordance with the sort of emergency. Further this is equipped with a steam balance calculator 10, a air bleeding mode calculator 11, a by-pass valve opening/closing calculator 12, a boiler evaporation calculator 13, a relay setting signal generator 14 whose input is connected with the outputs of the turbine load and air bleeding/setting device 8 and the load selecting and shutoff setting device 9, and an emergency action signal generator 15 connected with the inputs to the plant 2.

摘要： PURPOSE:To attain highly-reliable data transmission by reducing the data error of defect of more than one bit to its minimum by accurately orientating the defective bit position of a transmission line when transmitting numeric data with several fixed bits in parallel via bit parallel transmitter. CONSTITUTION:The transmission system which transmits several pieces of data equivalent to several bit areas 0 to n between 1st and 2nd data processors 1a and 1b is allowed to transmit two kinds of test data, ''1'' and ''0'', from processor 1a to processor 1b. From input 31 of a test pattern from processor 1a, bit (i) (0

摘要： PURPOSE:To reduce the number of CRT pictures and shorten the switching display time, by storing plural pieses of monitoring picture information, and constituting so that one of the information can be switched and displayed. CONSTITUTION:When it is detected by the CPU1 that an alarm state has occurred somewhere in the plant, the display picture information of the part where said alarm state has been detected is transmitted as monitoring picture information to the CRT device 4. The receiving - storage control part 41 of the device 4 inputs said information into the designated areas I-IV in the storage device 42. In this case, in case when there is no other monitoring picture information displayed on the display part 43, the monitoring picture information which has been transmitted from the CPU1 is displayed on the display part 43 immediately. If at that time, other monitoring information is displayed on the display part 43, the picture information which has been transmitted by operation of the picture selective operation part 3 is displayed on the display part 43. Also, the switching control part 45 is operated by handling the push-button of the operation part 3 corresponding to the areas I-IV of the device 42, and the monitoring picture information stored in said areas can be displayed on the display part 43.
