Under situation between speed-change area has been left in the position that is judged to be car 2, judge that by monitoring substrate 24 whether the speed of the car 2 that is calculated is less than the 1st constant hypervelocity pattern OS1 of portion (S4).Under the situation of the speed that is judged to be car 2, from monitoring that substrate 24 is to brake equipment 8 output services signals (S5) more than or equal to the 1st constant hypervelocity pattern OS1 of portion.Carry out the 1st braking maneuver (S6) of brake equipment 8 thus.
Under the situation of the speed that is judged to be car 2, judge that by monitoring substrate 24 whether the speed of car 2 is less than the 2nd constant hypervelocity pattern OS2 of portion (S7) less than the 1st constant hypervelocity pattern OS1 of portion.Under the situation of the speed that is judged to be car 2, from monitoring that substrate 24 is to control of braking substrate 25 output services signals (S8) more than or equal to the 2nd constant hypervelocity pattern OS2 of portion.Carry out the 2nd braking maneuver (S9) of brake equipment 8 thus by the control of control of braking substrate 25.And when being judged to be under the situation of speed less than the 2nd constant hypervelocity pattern OS2 of portion of car 2, continue to stop output (S10) from the working signal that monitors substrate 24.
On the other hand, under the situation in the position that is judged to be car 2 is between speed-change area, judge that by monitoring substrate 24 whether the speed of the car 2 that is calculated is less than the 1st variable hypervelocity pattern SETS1 of portion (S11).Under the situation of the speed that is judged to be car 2, from monitoring that substrate 24 is to brake equipment 8 output services signals (S12) more than or equal to the 1st variable hypervelocity pattern SETS1 of portion.Carry out the 1st braking maneuver (813) of brake equipment 8 thus.
Under the situation of the speed that is judged to be car 2, judge that by monitoring substrate 24 whether the speed of car 2 is less than the 2nd variable hypervelocity pattern SETS2 of portion (S14) less than the 1st variable hypervelocity pattern SETS1 of portion.Under the situation of the speed that is judged to be car 2, from monitoring that substrate 24 is to control of braking substrate 25 output services signals (S15) more than or equal to the 2nd variable hypervelocity pattern SETS2 of portion.Carry out the 2nd braking maneuver (S16) of brake equipment 8 thus by the control of control of braking substrate 25.And when being judged to be under the situation of speed less than the 2nd variable hypervelocity pattern SETS2 of portion of car 2, continue to stop output (S17) from the working signal that monitors substrate 24.
And the hypervelocity that promptly stops to move is set to the value greater than the 1st hypervelocity mode 32.Therefore even after the 1st braking maneuver of having carried out brake equipment 8, when further rising for a certain reason, the speed of car 2 reaches when promptly stopping the action hypervelocity, also can pass through governor 16 clamping speed controller ropes 19, emergency braking device carries out work.
In this elevator brake system, in safety device 23, set mutually different the 1st hypervelocity pattern and the 2nd hypervelocity pattern, safety device 23 makes brake equipment 8 carry out the 1st braking maneuver when the speed of car 2 reaches the 1st hypervelocity pattern, safety device 23 makes brake equipment 8 carry out the 2nd braking maneuver when the speed of car 2 reaches the 2nd hypervelocity pattern, thereby can select mutually different braking maneuver according to the hypervelocity grade of car 2.Thus can the hypervelocity of car 2 from carry out the transition to than low degree higher degree during in increase the braking force that imposes on drive pulley 6 gradually, can suppress the deceleration/decel of car 2 lowlyer.Therefore in the time of can reducing brake equipment 8 work to the impact of car 2.
And, in the 1st braking maneuver of when the speed of car 2 reaches five-star the 1st hypervelocity mode 32, being carried out, to whole braking forces of drive pulley 6 moment brake activation device 8; And reach in the 2nd braking maneuver of being carried out when its value is lower than the 2nd hypervelocity mode 33 of the 1st hypervelocity mode 32 in the speed of car 2, braking force is intended to relax adjustment to the impact of car 2, thereby the deceleration/decel that can further be in the hypervelocity of car 2 than the car under the low degree 2 suppresses lowlyer, can further reduce the impact to car 2.
And in above-mentioned example, be according to calculating the position of car 2 and speed from producing with the information of the velocity limiter coder 20 of the cooresponding signal of rotation of governor sheave 17, but the winch coder of the cooresponding signal of rotation of generation and drive pulley 6 also can be set, on winch 4 according to position and the speed of calculating car 2 from the information of winch coder.And the speed of the car 2 that compares with the speed of the 1st car 2 that compares of hypervelocity mode 32 with the 2nd hypervelocity mode 33 can also be for example according to coming out from the information calculations of mutually different coders such as velocity limiter coder 20 and winch coder.Also can in car 2, acceleration pick-up be set, or use the signal of existing scale device.
