Embodiment

Remote control module belongs to sequence pattern, as controls each way switch to power in order, starts motor.In master control After unit module receives distant place sequence order, you can give motor institute with the mutually secondary startup order in interval in a predetermined sequence Circuit switching.Successively in start-up course, any one motor start-up failure, then do not continue to start next in each circuit Platform, and stop the circuit having been turned on immediately.If after smooth start in normal course of operation, event occurs for any one motor Barrier, then other all motor also must hard stop.

Circuit switching, signal conditioning circuit of motor etc. are not only included in unit switch protection module, further comprises guarantor Protective function, major protective function are as follows：Earth leakage search/lockout, overvoltage protection, under-voltage protection, overload protection, open-phase protection, short circuit are protected Shield, earth leakage protective etc..Wherein, short circuit, disconnected phase, electric leakage belong to significant trouble, it is necessary to manually carry out manual confirmation reset, overvoltage, Under-voltage grade is protected to be alternative, can be configured in main control unit protection seting function.Each click operation is associated, when certain When platform motor breaks down, slave computer is uploaded to processing and the record that host computer main control unit carries out failure, to other operations In motor perform halt command and protection.

Handling result is mainly sent in unit switch protection module by main control unit module by CAN bus, to motor It is controlled.Main control unit module operating mode is divided into two kinds.If 6 way switch circuits are respectively 1#~6#, in mode 1, open Dynamic process can be described as：1# motor start first, and through (0~3s is adjustable) after a while, 3# motor start-ups, are delayed again (3~5s is adjustable), 4# motor start-ups, while 3# motor failures, into normal operation, wherein 3#, 4# motor is respectively Vulgar motor and high-speed motor, the combination which is suitable for elevating conveyor and crusher on working face start.Such as 1 # conducts Crusher, 3#, 4# are as elevating conveyor low speed and elevating conveyor high speed.2#, 5#, 6# switching circuitry can be used as back-up circuit, as 1#, 3# Or 4# switches break down, motor is accessed into back-up circuit, improves the flexibility of production.The control mode of pattern 2 It is to be set for the two-speed motor of coal working face driving scratch board conveyor, transporter head, 2 double speeds of tail are electronic It is confidential to ask co-ordination, since chain is in relaxed state, it is necessary to which the motor of head starts first, to draw before low rate start Nearly chain smooth starts, and is delayed after 3~5s, restarts tail slow-speed motor, after low speed operation 0~5s times, sends conversion The enabling signal of high speed, head, tail are switched to high-speed motor at the same time.This external system also provides automatic switchover mode for choosing Select, in an automatic switch-mode, finished when 2 slow-speed motors of frame head and tail successively start, 2 motor drop to specified electricity During stream, high speed switching signal is just sent.No matter after being also up in start-up course, any one motor breaks down Or starting failure, other motor must all be shut down.
