if m is larger than or equal to m3, the central control unit judges that the micro motor is started after time T4, and sets T4 to be 0.1 × (T1+ T2+ T3+ T4);
where Ti denotes the ith start time of the micro motor, and i is set to 1,2,3, and 4.
8. The anti-slip portable labor insurance shoe of claim 7, wherein said central control unit is further provided with a preset mass difference value including a first preset mass difference value Δ ms1, a second preset mass difference value Δ ms2 or a third preset mass difference value Δ ms3, wherein Δ ms1 < [ delta ] ms2 < [ delta ] ms 3;
after ti time, setting i to be 1,2,3,4, starting the micro motor by the control switch of the central control unit to push the mud pushing rod to push out the substances in the anti-skid groove, when the mud pushing plate rebounds, calculating the density in the anti-skid groove detected by the density detection sheet and the volume of the anti-skid groove by the central control unit to obtain a secondary measured mass ms, meanwhile, the central control unit is provided with a standard mass ms0 which does not need to be pushed out, wherein ms0 is less than m1, and when the detection and setting are completed, the central control unit compares the secondary measured mass ms with the standard mass ms0 which does not need to be pushed out:
if ms is less than or equal to ms0, the central control unit controls the switch to turn off the micro motor;
if ms is greater than ms0, the central control unit starts the micro motor again after judging Y time.
9. The anti-slip portable labor insurance shoe according to claim 8, wherein when the central control unit restarts the micro motor after determining Y time, the central control unit calculates a mass difference Δ ms as follows:
△ms＝(ms-ms0)×σ；
wherein σ represents a mass difference coefficient, and σ is set to ms/ms 0;
when the calculation is finished, the central control unit compares the quality difference value Delta ms with a preset quality difference value to determine the specific time for restarting,
if Δ ms is less than Δ ms1, setting Y to t1 × 0.6;
if the delta ms is not less than delta ms1 and less than delta ms2, setting Y as (t2-t1) multiplied by 0.6;
if the delta ms is not less than delta ms2 and less than delta ms3, setting Y as (t3-t2) multiplied by 0.6;
if the delta ms is more than or equal to the delta ms3, setting Y to be (t4-t3) multiplied by 0.6;
wherein ti represents the start time of the micro motor determined in combination with the mass of the substance in the anti-slip groove, and i is set to 1,2,3, 4.
10. The anti-slip portable labor insurance shoe of claim 9, wherein the central control unit is further provided with a preset micro motor start-up shading rate and a micro motor power coefficient, wherein the preset micro motor start-up shading rate includes a first preset micro motor start-up shading rate Ay1, a second preset micro motor start-up shading rate Ay2 and a third preset micro motor start-up shading rate Ay3, wherein A2 < Ay1 < Ay2 < Ay 3; the micro motor power coefficient comprises a first micro motor power coefficient zeta 1, a second micro motor power coefficient zeta 2, a third micro motor power coefficient zeta 3 and a fourth micro motor power coefficient zeta 4, wherein zeta 1+ zeta 2+ zeta 3+ zeta 4 is 1;
when the micro motor is started, the central control unit obtains the shielding rate when the micro motor is actually started and records the shielding rate as Aq, when the shielding rate is obtained, the central control unit compares the shielding rate Aq when the micro motor is actually started with the shielding rate when the micro motor is preset to be started so as to calculate the power when the micro motor pushes the mud pushing rod,
if Aq is less than Ay1, the central control unit selects zeta 1 to calculate the power of the miniature motor when pushing the mud pushing rod;
if Aq is more than or equal to Ay1 and less than Ay2, the central control unit selects zeta 2 to calculate the power of the miniature motor when pushing the mud pushing rod;
if Aq is more than or equal to Ay2 and less than Ay3, the central control unit selects zeta 3 to calculate the power of the miniature motor when pushing the mud pushing rod;
if Aq is larger than or equal to Ay3, the central control unit selects zeta 4 to calculate the power of the miniature motor when pushing the mud pushing rod;
when the central control unit selects ζ i to calculate the power when the micro motor pushes the mud pushing rod, i is set to be 1,2,3 and 4, the central control unit calculates the power F when the micro motor pushes the mud pushing rod, and the power F is set to be F0 × ζ i × Δ Af, wherein F0 represents preset mud pushing rod power and is set by the central control unit.
