【正文】 nt always Body control system, Is more advantageous to the display ships dynamic system function, Has developed mature today in the puter work, Is does not have the question The control system working selects on the position connection method to be good On the position machine uses the puter to join the multi Taiwan PLC control system Through puter management each PLC system work, And to collects the massive information carries on analysis processing toxin in control system working foundation, May more display the PLC system the function, Besides pletes the control function, Also may develop the dynamic system the breakdown diagnosis, Function and artificial intelligence system and so on engine room management。 The single plane (網(wǎng)絡(luò)化 ) develops to the system。 (3) The emergency blowingout protects When the collection controls Taiwan to have the blowingout to order, Then sends out the emergency blowingout the warning, Boiler blowingout (4)Heavy oil temperature control interconnection When choice heavy oil, The oil temperature is higher than 80 ℃ procedures to be able to move The oil temperature lowly is lower than this value, Sends out the warning, Boiler blowingout (5) Flame surveillance unusual interconnection When appears the ignition defeat, the midway flameout or the burning condition worsening, Sends out the flame surveillance to be unusual the warning, Boiler blowingout (6) Manual, automatic operation interconnection only when cuts the switch to set manually (is automatic) the position, only then allows carries on manually (is automatic) all operations (7) The 1 spray hole does not work, Or the air throttle has not started in a big way, The 2 spray hole does not work and so on 3 Hardware designs The hardware design mainly revolves the system the reliability and the consummation its function two goal carries on PC shaping The programmable foreword controller uses, the excellent craft manufacture advanced, its reliability is the general labor controls the microputer 4~6 to double, Therefore should stress from the control function angle chooses PC. Regarding the single plane, the medium scale, use in guaranteeing the boiler safe operation the automatic control system, To conserves energy the goal to be possible not to consider, Therefore does not need the PID control function Such system by condition control, sequential control primarily, By the switch quantity logic operation, the time, counts is in the majority, To aspect the and so on ponent running rate performance does not have the special request, Therefore may act according to the procedure to need the capacity (IO port number and memory size) makes the PC shaping The storage capacity (procedure step) may) * ∑ (IO) make the estimate according to empirical formula Q=6~10,If the user program is not big, Saves The accumulator capacity demand is easy to satisfy This system altogether must input the port, output port each 14 (if increase boiler water monitor function, Must again increase the input, output port each 4),Therefore uses Mitsubishi Corporation F130MR or F140MR is the controllerF130MR is the subminiature programmable foreword controller, Its input, outputs the port with PC machine to assemble in together, Does not need to choose the IO module againF1 series PC does not have breakdown time interval MTBF is 300,000 hours, The mutable (0~+55 ℃ ,Work。 When p2p,1, the 2 spray hole opens。 After closes the 2 spray hole, closes the order blowingout which the 1 spray hole, sweeps
