1) if the address receiving packet is No. ID of this node apparatus, a length of CONTROL_SIZE of packet data (2) byte, then be base station control instruction.Perform dependent instruction, process particular data bit value method following (perform just to start and The premise of anti-enabled instruction is that three phase electric machine is under halted state):

If 1. particular data bit value is 0x00, then for halt instruction, now processor unit 11 is to control machines Interface 27 exports three phase electric machine halt instruction, i.e. arranges GPG and GPC port data depositor zero-bit and is 0, arranges simultaneously GPC port data depositor second is 1, and removing GPC port data depositor second after the time delay time is 0, to PIN33 Exporting TTL low level with PIN35, and export a TTL high level pulse signal to PIN37 simultaneously, CPU checks three phase electric machine fortune The motor operating state of row feedback of status output interface 28 output, if motor does not stops, then repeats aforesaid operations；

If 2. particular data bit value is 0x01, being then positive enabled instruction, now processor unit 11 is first according to three-phase The reading information of motor operating state feedback 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 The motor operating state of output, if motor is still inverted status, then repeats above-mentioned stopping operation, then time delay section period, Retransmit positive enabled instruction, otherwise directly export the positive enabled instruction of three phase electric machine to control machines interface 27, the most just start It is 1 that instruction need to arrange GPG port data depositor zero-bit, arranges GPC port data depositor zero-bit and second simultaneously Being 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 rotates forward, then repeats aforesaid operations；

If 3. particular data bit value is 0x10, being then anti-enabled instruction, now processor unit 11 is first according to three-phase The readings information of motor operating state feedback 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 The motor operating state of output, if motor is still rotating forward state, then repeats above-mentioned stopping operation, then the time delay section period, Retransmit anti-enabled instruction, otherwise directly export the anti-enabled instruction of three phase electric machine to control machines interface, the most just starting and referring to Order need to arrange GPG port data depositor zero-bit and GPC port data depositor second is 0, arranges GPC port simultaneously Data register zero-bit is 1, and removing GPC port data depositor zero-bit after the time delay time is 0, exports one to PIN35 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 rotates forward, then repeats aforesaid operations；

2) if receiving packet is base station time synchronism instruction.Now reset time synchronized enumerator, restart meter Time, forward step 5 to；

3) if receiving packet not meet above-mentioned two situations, then this data invalid, forwards step 5 to.

Step 7 processor unit 11 resolution system controls packet data package, and after having performed system control instruction, reads The level value of PIN34 and PIN36 pin, it is thus achieved that the motor operating state letter of three phase electric machine running status feedback output interface 28 Breath, this status feedback signal packet of packing, cycle transmission three phase electric machine status feedback signal, forward step 5 to.

The workflow of manual-operated emergent control mechanism as shown in Figure 8, at the control node of 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 electricity tractor driver Dynamic emergency flight control mode is decided whether to select to use by manager self；In the operational approach of manual-operated emergent control mode, as Really manager wants emergent stopping, then manual operation stop button SB1, just starts if manager wants to meet an urgent need, then people Work first operates normally closed button SB1 makes three phase electric machine stop, and operates positive start button SB2 the most again and just starts, if manager thinks Meet an urgent need and instead start, then manually first operate normally closed button SB1 and make three phase electric machine stop, operating anti-start button SB3 more anti- Start.

Under case of emergency, system is optional takes manual-operated emergent control mode, and which is not only wireless instructions control mode Emergency operation mechanism under unusual condition, back mechanism, i.e. this control mode can realize wireless instructions control machine the most especially All functions of system.Both control modes to realize the degree of coupling extremely low, they can take con current control action, will not be mutual Impact, when wireless instructions mode controls after three phase electric machine just starts, if manager wants to stop, then he can have two kinds of choosings Selecting, wireless instructions control mode is attained by the same effect with manual-operated emergent control mode, the operation of other situations in like manner class Pushing away, here is omitted.The workflow of this control mode is as shown in Figure 8.
