If 2. particular data bit value is 0x01, for positive enabled instruction, now processor unit 11 is first according to three-phase
The reading information that motor operating state feeds back output interface 28 judges the running status of three phase electric machine, if inverted status, then to
Control machines interface 27 first exports three phase electric machine halt instruction, and CPU checks three phase electric machine running status feedback output interface 28
Output motor operating state, if motor still be inverted status, repeat above-mentioned stop operation, the then time delay section time,
Retransmit positive enabled instruction, otherwise directly export the positive enabled instruction of three phase electric machine to control machines interface 27, wherein just start
It is 1 that instruction need to arrange GPG port data depositor zero-bit, simultaneously setting GPC port data depositor zero-bit and second
It is 0, removing GPG port data depositor zero-bit after the time delay time is 0, exports a TTL high level pulse to PIN33
Signal, and export TTL low level to PIN35 and PIN37 simultaneously, CPU checks three phase electric machine running status feedback output interface 28
The motor operating state of output, if motor does not rotate forward, repeats aforesaid operations；
If 3. particular data bit value is 0x10, for anti-enabled instruction, now processor unit 11 is first according to three-phase
The readings information that motor operating state feeds back output interface 28 judges the running status of three phase electric machine, if rotating forward state, then to
Control machines interface 27 first exports three phase electric machine halt instruction, and CPU checks three phase electric machine running status feedback output interface 28
Output motor operating state, if motor still be rotating forward state, repeat above-mentioned stop operation, the then time delay section time,
Retransmit anti-enabled instruction, otherwise directly export the anti-enabled instruction of three phase electric machine to control machines interface, wherein just start and refer to
Order need to arrange GPG port data depositor zero-bit and GPC port data depositor second is 0, arrange GPC port simultaneously

Individual TTL high level pulse signal, exports TTL low level to PIN33 and PIN37 simultaneously, and CPU checks that three phase electric machine running status is anti-
The motor operating state of feedback output interface 28 output, if motor does not rotate forward, repeats aforesaid operations；
2) if receiving packet is base station time synchronism instruction.Now reset time coincidence counter, restarts to count
When, go to step 5；
3) if receiving packet not meet above-mentioned two situations, this data invalid, go to step 5.
Step 7 processor unit 11 resolution system control packet packet, and after having executed system control instruction, read
The level value of PIN34 and PIN36 pin, obtains the motor operating state letter that three phase electric machine running status feeds back output interface 28
Breath, this status feedback signal packet of packing, the cycle sends three phase electric machine status feedback signal, goes to step 5.
The workflow of manual-operated emergent control mechanism is as shown in figure 8, control node in above-mentioned three phase electric machine Comprehensive Control
Step 6 in the operation method step of device can be replaced by the corresponding operating method of manual-operated emergent control mode, three phase electric machine handss
Dynamic emergency flight control mode is decided whether to select to use by manager itself；In the operational approach of manual-operated emergent control mode, such as
Fruit manager wants emergent stopping, then manually operate stop button SB1, if manager wants to meet an urgent need just started, people
Work first operates normally closed button SB1 so that three phase electric machine is stopped, and then operates positive start button SB2 just to start, if manager thinks again
Meet an urgent need and instead start, then manually first operate normally closed button SB1 so that three phase electric machine is stopped, then operating anti-start button SB3 anti-again
Start.
Under case of emergency, system may be selected to take manual-operated emergent control mode, and which is not only wireless instructions control mode
Emergency operation mechanism under unusual condition, even more back mechanism simultaneously, that is, this control mode can realize wireless instructions control machine
The institute of system is functional.Both control modes realize that the degree of coupling is extremely low, they can take con current control action, will not be mutual
Impact, after wireless instructions mode controls three phase electric machine just to start, if manager wants to stop, then he can have two kinds of choosings
