From leading section 23 with the 1st coder 8a and the cooresponding signal of the 2nd coder 8b, be input to towing machine control operational part 21b by towing machine control Department of Communication Force 21c.Towing machine control operational part 21b utilizes computing machine to constitute, and carries out calculation process according to the signal from leading section 23, generates the command signal that is used to control towing machine drive division 21a.
Signal from leading section 23 is input to the 1st control of braking operational part 22a and the 2nd control of braking operational part 22b by control of braking Department of Communication Force 22e.The 1st control of braking operational part 22a utilizes computing machine to constitute, and according to carrying out calculation process with the cooresponding signal of the 1st coder 8a, generates the signal of the on/off that is used to control the 1st deceleration/decel master cock 15.And the 2nd control of braking operational part 22b utilizes computing machine to constitute, and according to the signal from the 2nd coder 8b, carries out the identical calculation process with the 1st control of braking operational part 22a, generates the signal of the on/off that is used to control the 2nd deceleration/decel master cock 16.
And the 1st control of braking operational part 22a and the 2nd control of braking operational part 22b can carry out reading and writing of shared data to the control of braking share storage 22c of portion.In addition, the 1st control of braking operational part 22a and the 2nd control of braking operational part 22b be by the control of braking share storage 22c of portion, and each other incoming signal and operation result compared.And, when incoming signal exclusive disjunction result's difference surpasses permissible value, to the control of braking signalling trouble 22d of portion input fault detection signal.
In addition, when car 1 is promptly stopped, the on/off of brake control section 22 control the 1st deceleration/decel master cocies 15 and the 2nd deceleration/decel master cock 16, so that the deceleration/decel of car 1 can be not excessive, thus the braking force (deceleration/decel control) of adjustment brake equipment 7.
The following describes action.When car 1 was advanced, the 1st front end operational part 23a and the 2nd front end operational part 23b carried out predetermined computing according to the signal from the 1st coder 8a and the 2nd coder 8b, detected the rotative speed that drives rope sheave 5.
At this moment, the 1st front end operational part 23a is by the front end share storage 23c of portion, to comparing from the signal of the 1st coder 8a with from the signal of the 2nd coder 8b.And, when the difference of these signals is in predetermined incoming signal permissible error scope, carry out necessary calculation process, operation result is write the front end share storage 23c of portion.
Equally, the 2nd front end operational part 23b is by the front end share storage 23c of portion, to comparing from the signal of the 2nd coder 8b with from the signal of the 1st coder 8a.And, when the difference of these signals is in predetermined incoming signal permissible error scope, carry out necessary calculation process, operation result is write the front end share storage 23c of portion.
And the 1st front end operational part 23a and the 2nd front end operational part 23b read the operation result of other system from the front end share storage 23c of portion, compare with the operation result of native system.When the difference of operation result is in predetermined operation result permissible error scope, operation result is write the 23e of front end communication portion.
But, when the poor exclusive disjunction result's of the incoming signal of the 1st coder 8a and the 2nd coder 8b difference is not in the permissible error scope, the 1st front end operational part 23a and the 2nd front end operational part 23b are judged to be and have produced that certain is unusual, and fault detection signal is input to the front end signalling trouble 23d of portion.
The operation result of the 1st front end operational part 23a and the 2nd front end operational part 23b and the fault detection signal that is input to the front end signalling trouble 23d of portion send to towing machine control part 21 and brake control section 22 by the 23e of front end communication portion.At this moment, the processing data constantly of additional the 1st front end operational part 23a and the 2nd front end operational part 23b in the statement of operation result.Thus, the processing of the 1st front end operational part 23a and the 2nd front end operational part 23b is reflected in the computing of towing machine control part 21 and brake control section 22 constantly.And,, can improve the reliability and the precision of towing machine control and control of braking the determinating reference of time as trouble diagnosing.
And the information at additional fault generation position (unusual position) sends in fault detection signal.Thus, the information at fault generation position is reflected in the computing of towing machine control part 21 and brake control section 22.
For example, be always at 0 o'clock at the signal from the 1st coder 8a, expression fault generation position is that the information of the 1st coder 8a is attached in the fault detection signal, sends to towing machine control part 21 and brake control section 22.
Thus, in brake control section 22, carry out computing by the 1st control of braking operational part 22a and the 2nd control of braking operational part 22b, generation is used to make brake equipment 7 to carry out the instruction of braking maneuver, and operation result sends to leading section 23 by control of braking Department of Communication Force 22e.And, make brake equipment 7 carry out braking maneuver by leading section 23.
And in towing machine control part 21,21b carries out computing by towing machine control operational part, generates the instruction that the lifting that is used to make car 1 stops, and by towing machine drive division 21a towing machine motor 6 is stopped.
Below, the action of the brake control section 22 when 23 pairs of normal operation results of leading section communicate is described.Fig. 3 is the diagram of circuit of action of the brake control section 22 of presentation graphs 2, and the 1st control of braking operational part 22a and the 2nd control of braking operational part 22b be executed in parallel processing shown in Figure 3 simultaneously.
In Fig. 3, the 1st control of braking operational part 22a and the 2nd control of braking operational part 22b at first handle the initial setting (step S1) of needed a plurality of parameters.In this example, set following parameter: be used for the driving rope sheave speed V0[m/s that car stops to judge], stop the driving rope sheave speed V1[m/s of deceleration/decel control] and the 1st threshold gamma 1[m/s that is used to judge the deceleration/decel that drives rope sheave 5
2] and the 2nd threshold gamma 2[m/s
2] (γ 1＜γ 2).
According to the predefined sample period, periodically carry out the processing behind the initial setting repeatedly.That is, the 1st control of braking operational part 22a and the 2nd control of braking operational part 22b obtain signal (step S2) from leading section 23 according to the predetermined cycle.Then, according to the signal from leading section 23, computing drives rope sheave deceleration/decel γ [m/s
2] (step S3).
Then, the 1st control of braking operational part 22a and the 2nd control of braking operational part 22b judge whether drive rope sheave speed (motor rotative speed) V greater than stopping to judge speed V0 and driving rope sheave deceleration/decel γ greater than the 1st threshold gamma 1.And if do not satisfy this condition, then generation is used for the 1st braking is braked the instruction (step S9) that is made as off-state with electromagnetic relay 14 with electromagnetic relay 13 and the 2nd, and 22e sends to leading section 23 with this instruction by the control of braking Department of Communication Force.Thus, the 1st restraining coil 11 and the 2nd restraining coil 12 are cut off power supply, can not carry out deceleration/decel control.
And, under the situation of V＞V0 and γ＞γ 1 that satisfies condition, the 1st control of braking operational part 22a and the 2nd control of braking operational part 22b generate and are used to make the 1st braking to brake the instruction (step S5) of using electromagnetic relay 14 closures with electromagnetic relay 13 and the 2nd, and 22e sends to leading section 23 with this instruction by the control of braking Department of Communication Force.
Here, when car 1 promptly stops, energising to towing machine motor 6 also is cut off, thereby from after producing urgent halt instruction to braking force actual play a role during, because the overbalance of the loading of car 1 side and the loading of counterweight 2 exists the situation of car 1 acceleration and the situation that car 1 slows down.
In the 1st control of braking operational part 22a and the 2nd control of braking operational part 22b, if γ≤γ 1, be judged to be then that car 1 quickens after just producing urgent halt instruction, the 1st braking is made as off-state with electromagnetic relay 13 and the 2nd braking with electromagnetic relay 14, so that braking force plays a role as early as possible.And,, make the 1st braking implement deceleration/decel control with electromagnetic relay 14 closures, so that deceleration/decel can be not excessive with electromagnetic relay 13 and the 2nd braking if γ＞γ 1 then is judged to be car 1 and slows down.
In deceleration/decel control, the 1st control of braking operational part 22a and the 2nd control of braking operational part 22b judge that whether driving rope sheave deceleration/decel γ is greater than the 2nd threshold gamma 2 (step S6).And, if γ＞γ 2, in order to suppress to drive rope sheave deceleration/decel γ, generation makes the instruction (step S7) according to predefined duty cycle of switching (for example 50%) on/off of the 1st deceleration/decel master cock 15 and the 2nd deceleration/decel master cock 16, and 22e sends to leading section 23 with this instruction by the control of braking Department of Communication Force.Thus, the 1st restraining coil 11 and the 2nd restraining coil 12 are applied in predetermined voltage, the braking force of control brake device 7.At this moment, the 1st deceleration/decel master cock 15 and the 2nd deceleration/decel master cock 16 on/off synchronously mutually.
And if γ≤γ 2, then the 1st deceleration/decel master cock 15 and the 2nd deceleration/decel master cock 16 are still off-state.Then, the 1st control of braking operational part 22a and the 2nd control of braking operational part 22b control and stop to judge (step S8).In control stops to judge, judge whether to drive rope sheave speed V less than threshold value V1.And, if V 〉=V1 then directly returns input and handles (step S2).And,, return input then and handle (step S2) if V＜V1 then generates the 1st braking is braked the instruction (step S9) that is made as off-state with electromagnetic relay 14 with electromagnetic relay 13 and the 2nd.
Here, Fig. 4 be illustrated in the driving rope sheave speed that just produces when car 1 slows down after the urgent halt instruction, drive the rope sheave deceleration/decel, instruction diagram that the 1st braking changes with time of the state of the state of electromagnetic relay 14 and the 1st deceleration/decel master cock 15 and the 2nd deceleration/decel master cock 16 with electromagnetic relay 13 and the 2nd braking.
Producing when promptly stopping car 1 deceleration that will begin in a minute.And when when time T 1 deceleration/decel reaches γ 1, the 1st braking is braked with electromagnetic relay 14 closures with electromagnetic relay 13 and the 2nd, when when time T 2 deceleration/decels reach γ 2, and the 1st deceleration/decel master cock 15 and the 2nd deceleration/decel master cock 16 on/off.Then, when driving rope sheave speed less than V1, the 1st braking disconnects with electromagnetic relay 14 with electromagnetic relay 13 and the 2nd braking, stops based on the deceleration/decel control of the 1st deceleration/decel master cock 15 and the 2nd deceleration/decel master cock 16.
