It is changed the 2nd brake electric current in embodiment to intermittently discharge the 2nd brake 102B, but the 2nd brake can also be made
Electric current becomes certain electric current and is continuously applied certain brake force to sheave by the 2nd brake 102B.
In section (d), the state that operation control unit 32 detects hypervelocity of rescuing is shown.Car position speed detecting portion 31
The car position inputted from safety governor 1 and velocity information output 23 are received, detects the sheet in current elevator
Number terraced car position and speed, and export the value detected.In the case where the value detected is hypervelocity, fortune is rescued
Row control unit 32 rises overspeed detection instruction, and the mobile grant instruction of brake carriage and brake are improved instruction and are set as
0.The current-order for giving the 1st brake current control circuit 21A and the 2nd brake current control circuit 21B is set as a result,
It is 0, brakes carriage.Although at this point, the 2nd brake 102B may since certain problem is to can not make carriage brake,
It is by being braked using the 1st standby brake 102A so as to more safely braking carriage.
Fig. 4 shows the flow chart for rescuing operation control.In step s101, rescue operation control unit 32 judge from rescue transport
Row starts unlatching (the beginning)/closing (stopping) for rescuing operation sign on that test section 30 exports.Start to refer to rescuing operation
It enables in the case where closing, ends processing.In the case where rescuing operation sign on unlatching, it is transferred to step S102.Rescue fortune
The condition that row sign on is opened is normally set up are as follows: passenger is held in carriage and motor etc. is since certain exception leads to nothing
The case where method drives etc..In addition, though be referred to as rescue operation, if but not necessarily passenger is held in carriage, multiplying
Needs can also carry out this control in the state of rescuing operation when visitor takes.
In addition, as operation condition at this time, it is also desirable to brake regular event.Rescue the item that operation sign on is closed
Part setting are as follows: in normal operation or implement rescue operation in reach nearest floor can opening position when or detect to make
When the exception of dynamic device.
It in step s 102, whether is 0 to determine to car speed V.It is exported in car position speed detecting portion 31
Car speed V be 0 in the case where, rescue operation control unit 32 be judged as that carriage is in halted state and can start to rescue fortune
Row, and advance to step S104.In the case where car speed V is not 0, carriage is moved for some reason, because before this
Proceed to the step S103 for stopping carriage.
In step s 103, operation control unit 32 is rescued to set the mobile grant instruction of brake carriage and brake raising instruction
It is 0, to carry out the braking using two brakes.
In step S104, brake releases the control portion 33 and will be used to that the brake raising of unilateral brake release to be made to refer to
Order is set as opening, and current-order is sent to the brake current control circuit for wanting that side of release.
In step s105, it detects to be in the state improved using the brake that step S104 is improved.Brake is enhanced logical
The switch of the mechanical action for detecting brake such as brake detection switch is often used to detect.In addition, the raising of brake
It can be either side, but for example can also alternately be switched so that when running for the first time be the 1st brake 102A, run next time
2 brake 102B of Shi Wei.Alternately switch the mill so as to make the 1st brake 102A and the 2nd brake 102B in this way
Damage equalization.In addition, in step S105 in the case where failing to detect that brake improves, due to that can not expect predetermined raising
Brake regular event, therefore stop this operation.More specifically, it is transferred to step S103.
In step s 106, the mobile grant instruction of brake carriage is set as opening by carriage mobile control division 34.From carriage
Mobile control division 34 sends current-order to the brake current control circuit that the brake mobile with control carriage is connected.This
When, carriage will be made to become set speed, current-order is set and sent as target value.In addition, set speed is ratio
Be detected as hereinafter described in the speed of overspeed value want low speed.
In step s 107, based on the speed by the calculated carriage of car position speed detecting portion 31, operation control is rescued
Portion 32 detects car speeding.In the case where current car speed is bigger than overspeed value, it is transferred to step S108.
Operation control unit 32 is rescued in step S108 rises overspeed detection instruction, and makes the mobile grant instruction of brake carriage
And brake improves instruction as 0.The current-order for correspondingly giving each brake current control circuit becomes 0, system
Dynamic device is not attracted to carry out sheave braking of the braking to implement carriage.Carriage is braked in this case, and passes through calling dimension
Shield person implements to rescue.In addition overspeed value is set in the speed of governor movement or less.Moreover, for safer mesh
, braking under the lower-speed state influence of acceleration change for passenger is smaller, therefore can also transport with such as maintenance
Speed of service when scanning frequency degree, construction is correspondingly set.In addition, in this step though it is shown that hypervelocity example, but
It is that can also the threshold value be for example set as car position, and advance with carriage and excessive correspondingly apply braking.The speed of carriage
In the case where lower than overspeed value, it is transferred to step S109.
In step S109, car position speed detecting portion 31 receives the car position inputted from safety governor 1
And velocity information output 23, and detect this number in current elevator terraced car position and speed, rescue operation
Control unit 32 judges whether carriage reaches nearest floor.Step S110 is transferred in the case where reaching nearest floor.
In step s 110, operation control unit 32 is rescued to set the mobile grant instruction of brake carriage and brake raising instruction
It is 0, to make two brakes become on-position and make car stationary.It rescues operation control unit 32 car door is discharged and tied
Beam rescues operation.In the case where not reaching nearest floor, the processing for being back to step S107 is carried out.
According to above structure, electric life controller does not act on the braking of the standby mode of brake force by preparation in rescuing operation
Device, so as to ensure the brake force of standby brake.Therefore, brake force is being controlled using other brakes so that sedan-chair
When compartment is mobile, even if carriage be in the case that overspeed condition can not make its braking using other brakes, benefit can also be passed through
It is braked with the standby brake of brake force is ensured, to stop with making car safety.
In addition, since both the brakes for making dual intermittently switch, thus the abrasion of the hoof of brake simultaneously into
Row.Since abrasion meeting is so that the brake force of brake reduces, according to the development situation of abrasion, the speed of carriage can be than the speed of anticipation
Degree quickly moves, it may sometimes be difficult to be controlled the speed of carriage by discharging repeatedly for brake, sometimes brake
Hoof can not eventually brake sheave, so that carriage can not stop at specified position.In the present embodiment, as described above, even if
The redundancy that can also ensure that the brake force of brake when operation is rescued, therefore is able to suppress the generation of above-mentioned condition.
In the present embodiment, carried out in the case where brake is the 1st brake 102A and the 2nd brake 102B this 2
Illustrate, but 3 or more can also implement.Even if in discharging brake in the case where 1 or more brake, if it is remaining its
His brake can be such that carriage braking then can also implements.
