（2）When speed reduces to 0m/s, stop timing and record the time T1 and traveled distance value S2 of current timer record, then
Braking ability index is accordingly：Braking time is T1；Braking distance ABS is S1-S2；Braking deceleration a=V1/T1, if system
Dynamic deceleration is less than 1.5m/s2Then alert, and all detection informations in man machine interface are shown in real time and recorded；
（3）When occur brake hard when, PLC module according to currently by incremental encoder detection values for actual speed V1, according to
Braking deceleration is 1.5m/s2Calculating deceleration time is designated as T2, and starts timer T3；
（4）Work as T3-T2>If speed is changed into " 1 " from " 0 " still without 0m/s, PLC module output point Q1 states is reduced to during 3s, electricity
Gas braking control relay adhesive, enabling actuating device carries out electric braking to the secondary upper electricity of motor, and shows in man machine interface
Show corresponding warning message.
The invention has the beneficial effects as follows：
1) continuous monitoring to gate control system braking ability is realized with record, the preventive maintenance for gate control system provides ginseng
Examine；
2) realize the secondary electric electric braking control of the automatic diagnosis to lock control failure state and actuating device, it is to avoid therefore
The further extension of barrier；
3) data record and police instruction adopt Human machine interface, communications protocol to adopt MPI standard industrial protocol, system knot
Structure is simple, easy to operate, and information is comprehensively, intuitively；
4) device does not affect the driving logic and technique protection of original lift system, is conducive to raising to carry independently of electric-control system
The safety of the system of liter.
