Braking force control system 20 is according to adaptor union command signal Sc1, and generation is used for the on/off of the energising of restraining coil adaptor union 23 is provided the adaptor union command signal Sc2 of instruction, and exports to signal switching part 26.And braking force control system 20 is according to brake command signal Sb1, and generation is used to control the brake control signal Sb2 of the voltage that imposes on restraining coil 22, and exports to signal switching part 26.
Signal switching part 26 produces the brake control signal Sb3 that the on/off that is used for the energising of restraining coil adaptor union 23 provides the adaptor union command signal Sc3 of instruction and is used to control the voltage that imposes on restraining coil 22.
Under braking force control system 20 normal situation, promptly not under the situation of input fault detection signal Sabn, adaptor union command signal Sc3 is exactly adaptor union command signal Sc2, and brake control signal Sb3 is exactly brake control signal Sb2.
Relative therewith; Under the situation of the fault that detects braking force control system 20; Promptly imported under the situation of fault detection signal Sabn, it is invalid that signal switching part 26 makes from the adaptor union command signal Sc2 of braking force control system 20 and brake control signal Sb2, according to adaptor union command signal Sc1 and the brake command signal Sb1 from control device for running the engine 21; Control is to the energising of restraining coil adaptor union 23, and the voltage of control brake coil 22.
Like this, whether signal switching part 26 according to detecting fault at braking force control system 20, switch control that braking force control system 20 carries out effectively/invalid.And when detecting the fault of braking force control system 20, the control that signal switching part 26 carries out braking force control system 20 is invalid, utilizes the action command signal that is generated by control device for running the engine 21 that brake equipment 7 is moved.
Fig. 3 is the diagram of circuit of the deceleration/decel control action of expression braking force control system 20 shown in Figure 1, and the 1st and the 2nd operational part of braking force control system 20 is executed in parallel processing as shown in Figure 3 simultaneously.In Fig. 3, braking force control system 20 at first carries out initial setting (step S1) to handling needed a plurality of parameter.In this example, set following parameter: the car speed of in car stops to judge, using (driving rope sheave speed) V0 [m/s], make threshold value I0 [A] and the 1st and the 2nd threshold gamma 1 [m/s of car deceleration/decel of the current value of car speed V1 [m/s] that deceleration/decel control stops, restraining coil 22
2], γ 2 [m/s
2] (γ 1＜γ 2).
Periodically carry out the processing behind the initial setting times without number according to the predefined sampling period.That is, braking force control system 20 is taken into the signal (step S2) from sensor groups such as towing machine coders 10 with the predetermined cycle.Then, according to signal from towing machine coder 10, computing car speed V [m/s], car deceleration/decel γ 1 [m/s
2] (step S3).
Then, whether judgement car 1 is in and promptly stops in the action (step S4).Specifically, greater than stopping to judge speed V0 and braking current value when stopping to judge current value 10, braking force control system 20 is judged to be car 1 and is in and promptly stops in the action in car speed (motor rotative speed).Promptly do not stop then not implement deceleration/decel control (step S10) in the action if be not in.
Promptly stop to judge that then whether car deceleration/decel γ is greater than the 1st threshold gamma 1 (step S5) in the action if be in.And, if γ≤γ 1 does not then implement deceleration/decel control (step S10).And, if γ＞γ 1, then degree of reducing speed now control (step S6).
At this; When promptly the stopping of car 1; Energising to towing machine motor 6 also is cut off; Thereby from produce urgent halt instruction play the braking force practical function during because the overbalance of the load of car 1 side and the load of counterweight 2, the situation that exists situation that car 1 is accelerated and car 1 quilt to be slowed down.
If γ≤γ 1, braking force control system 20 is judged to be that car 1 is accelerated immediately after producing urgent halt instruction, thereby does not implement deceleration/decel control, but applies maximum braking force at once, so that braking force plays a role as early as possible.And if γ＞γ 1, braking force control system 20 is judged to be car 1 and is slowed down, and implements deceleration/decel control so that deceleration/decel can be not excessive.
In deceleration/decel control, braking force control system 20 judges that whether car deceleration/decel γ is greater than the 2nd threshold gamma 2 (step S7).And, if γ＞γ 2 then makes deceleration/decel master cock (not shown) on/off with predefined duty cycle of switching (for example 50%), so that suppress car deceleration/decel γ (step S8).Thus, restraining coil 22 is applied in predetermined voltage, and the braking force of control brake device 7.
And, if γ≤γ 2 then keeps the open circuited state of deceleration/decel master cock.Then, braking force control system 20 is controlled and is stopped to judge (step S9).In control stops to judge, judge that whether car speed V is less than threshold value V1.And, if V >=V1 then directly turns back to input and handles (step S2).And if V＜V1, then end minus speed control (step S10) turns back to input and handles (step S2).
Below, Fig. 4 is the diagram of circuit of the abnormity diagnosis action of expression braking force control system 20 shown in Figure 1.The moment that each later processing of (step S2) finishes is handled in the input of the 1st and the 2nd operational part of braking force control system 20 in Fig. 3, calls diagnostic process shown in Figure 4.
In abnormity diagnosis action, judge matching (step S11) from the operation values of the input value of sensor and/or the 1st and the 2nd operational part.Specifically, not unusual if the difference of input value exclusive disjunction value in predetermined scope, then is judged to be, turn back to next processing among Fig. 3.And, surpass under the situation of preset range in the difference of input value and/or operation values, be judged to be unusually, to signal switching part 26 output fault detection signal Sabn (step S12).
Fig. 5 is that expression is to the 1st and the 2nd threshold value of the car deceleration/decel of braking force control system shown in Figure 1 20 settings and the diagram of curves of the relation between the car position.The the 1st and the 2nd operational part to braking force control system 20 is set as follows, and the 1st and the 2nd threshold gamma 1, γ 2 are changed according to car position according to shown in Figure 5.Specifically, set and to become near make the terminal floor the 1st and the 2nd threshold gamma 1, γ 2 along with towards terminal floor and increase gradually.
