  For safety reasons, the braking means for braking the cable carrying equipment should be inspected regularly. In order to carry out such an inspection under conditions that are as close as possible to the operating state, the braking should be inspected with the transport equipment loaded.

  In the prior art, a configuration is known in which a load is loaded on a transportation facility before an inspection operation is performed in a braking means. By loading the bottom load in this way, it is possible to simulate the normal operation of the transport equipment that is driven in the loaded state. However, loading the load in this way is a simulation operation that requires a lot of handling operations that increase the time and cost for inspecting the braking means.

Recording the calibration reference characteristic curve when the braking means is used in the transport equipment driven in an unoperated state.

Preferably, the preliminary stage further includes a first step of adjusting the braking means. Thereby, the method of the present invention enables accurate diagnosis.
The preliminary stage further includes a confirmation operation for confirming the calibration, wherein the confirmation operation is performed in a state where the transport equipment is not loaded, and according to the control curve “F = f (t)”. Using the braking means for the equipment and recording a confirmation characteristic curve when the transport equipment is being driven by the drive means controlled in a closed loop based on a configured setting signal; and the confirmation characteristics Comparing a curve with the calibration reference characteristic curve.

Thereby, this work can aim at consistency of a calibration stage.
The control curve “F = f (t)” preferably extends based on a constant function “K = f (t)” so that the simulation is longer than the deceleration time of the calibration step.

  The inspection step includes the step of using the braking means in the facility when the transport facility is operating in an unloaded state, recording a no-load characteristic curve, and the no-load characteristic curve. And comparing with a pre-recorded no-load calibration reference characteristic curve.

The no-load calibration reference characteristic curve is a curve that is recorded when the braking means is used in the transport facility that is operating in an unloaded state.

The control curve “F = f (t)” is recorded by measuring the deceleration of the cable.
The method preferably uses an index of the position of at least one vehicle driven by the cable. This allows a variety of records to be made for similar load distribution in the cable.
For cable transport equipment where the braking means is pneumatic or hydraulic means, the inspection stage records a pressure change curve “Pt = f (t)” indicating the pressure change when using the braking means. Preferably, the method includes a step and a step of comparing “Pt = f (t)” with a predetermined curve “Pe = f (t)”.
The curve “Pe = f (t)” is a pressure change curve recorded in the preliminary stage when the braking means is used.

As a result, these curves can determine whether or not the operation deviation value is related to the hydraulic or pneumatic control means.

It is preferable to further include a position indexing means for attaching.

Fig. 5 shows a characteristic curve in a first form of the invention, which is recorded during the use of braking means in a transport facility operating in the loaded state, the characteristic curve being a cable deceleration curve. “Vec = f (t)”. Loaded by driving means controlled in a closed loop based on a set signal constituted by the calibration reference deceleration curve “Vec = f (t)” and the deceleration curve “Vec = f (t)” of FIG. The drive means control curve “F = f (t)” recorded when the braking means is used in a transport facility that is driven in the absence of this condition. The calibration reference deceleration curve “Vec = f (t)”, the drive means control curve “F = f (t)”, and the cable deceleration curve “Vv = f (t)” recorded in the calibration check operation are shown. The curves of FIGS. 1 and 2 and three deceleration test curves “Vtc = f (t)” when the braking is too strong, adjusted correctly and too slow are shown.

  In the following detailed description, “closed loop” is used. This closed loop performs servo control that compares the set value with the output value in order to change the output value so that the output value approaches the set value. means.

  Also, in the following description, when referring to a variable that is characteristic of the drive means and is proportional to the force or drive torque acting on the cable, such variable is the power supply selected for the drive means. Based on the type, for example, it may be a modulation frequency of a converter that supplies power to the driving means, or an electric control variable such as a variable voltage or current for supplying power to the driving means. This variable may be a mechanical variable that is detected directly in the transport facility, such as the tension of the drive cable, the torque of the drive means, etc.

  Typically, a cable transport facility is composed of at least two stops, between which at least one or more vehicles, such as cable cars, are towed from one of the stops to the other. A loop is formed by two mobile traction cables. These vehicles may be suspended from a moving cable that drives the vehicle. Alternatively, as is common practice for large capacity installations, these vehicles may be suspended from a fixed cable by a suspension arm with rotating wheels and driven along the fixed cable by a mobile tow cable. May be.

  The drive means can drive the cable. For example, the drive means includes one or more electric motors, a drive pulley, and a clutch, and is configured by a transmission that transmits motion between the motor and the drive pulley.

  Furthermore, the transport equipment is provided with braking means. The braking means typically includes one electromagnetic brake that cuts off power to the motor, one or more service brakes used for normal braking of the transport equipment, and one or more emergency brakes. Contains.

In one form of the invention, the service brake acts on the drive shaft of the drive means, while the emergency brake acts directly on the drive pulley.
In one variation, the braking means is a hydraulic or pneumatic brake. For example, this braking means is a braking means that is switched to a braking start state by a hydraulic or pneumatic means such as an actuator and a mechanical return means such as a spring that can return the braking means to its non-braking position. .

  The transportation facility further includes a control device for controlling the facility. The control device includes at least a control unit for controlling the driving unit and a control unit for controlling the braking unit. Preferably, the control device further includes a safety device capable of interrupting power supply to the driving means as soon as the braking means is driven at a driveable position. The method according to the invention includes the step in which the driving means must operate simultaneously with the braking means. For this reason, the control device of the transport equipment includes a switching device for switching the safety device between its main driving position and a passive position that allows the driving means and the braking means to operate simultaneously.

  The control device further includes a diagnostic device. The diagnostic apparatus includes data recording means connected to the driving means and the braking means, and includes detection means for detecting the speed of the cable, detection means for detecting a variable indicating the characteristics of the driving means, and the position of the vehicle. Information is taken from indexing means for indexing and detection means for detecting pressure in the braking means.

In one form, the variable indicating the characteristics of the driving means is a current flowing through the driving means.
In one variation, the control device and the diagnostic device are constituted by a console and an automatic logic controller. It should be noted that the present invention is not limited to this embodiment. Any suitable computer technology or electronic control device can be used.

  In a preferred form of the invention, the diagnostic method for diagnosing the braking means comprises a pre-calibration stage in which the transport equipment can be started, i.e. the transport equipment can be commissioned.

In this calibration phase, the braking means of the transport equipment is pre-adjusted to the regulation setting state.
This calibration phase comprises a first step, in which braking means are used on the transport equipment operating in the loaded state and a calibration reference characteristic curve is recorded. In the illustrated embodiment, the calibration reference characteristic curve is a cable deceleration curve “Vec = f (t)” (see “1” shown in FIG. 1).

It should be noted that in this step, the driving means is stopped when the braking means is used.
If the braking means is pneumatic or hydraulic, in this step, a pressure change curve “Pe = f (t)” indicating a change in pressure in the braking means when the braking means is used in a transport facility. Can also be recorded.

  In the second step, the braking means is used in a transport facility that is driven by the drive means in an unloaded state, which drive means is the above-mentioned calibration reference characteristic curve, ie the deceleration curve “Vec = f” shown. Control is performed in a closed loop based on the setting signal constituted by (t) ". The closed loop control device compares the actual deceleration of the cable with the set deceleration “Vec = f (t)” and activates the drive means to obtain an actual deceleration corresponding to the set deceleration. In this step, the drive means control curve “F = f (t)” (see “2” shown in FIG. 2) is recorded.

  In the first embodiment shown in FIG. 2, the control curve 2 corresponds to the change in the current intensity flowing through the driving means. Note also that the above control curve is obtained by detecting any variable related to the force generated by the drive means in the cable, the drive torque, or the instantaneous power supplied by the drive means. Should.

  In this way, the calibration phase can obtain a control curve “F = f (t)” (see “2”) for the control of the drive means, which is operated in an unloaded state. It should be noted that it is possible to simulate the force of the load when braking means are used in the carrying equipment.

  Furthermore, it should be noted that the control curve F = f (t) extends based on a constant function “K = f (t)” (see “7”). It should be noted that this constant function makes it possible to simulate the load in a time longer than the time for the cable to decelerate in the second deceleration step.

  Furthermore, in the second step described above, it is also possible to record the pressure displacement curve “Pe1 = f (t)” and confirm that this corresponds to the previously recorded curve “Pe = f (t)”. .

  Braking means used for transport equipment driven in an unloaded state by driving means controlled in a closed loop based on a set signal constituted by a control curve “F = f (t)” (see “2”) In doing so, it is desirable to confirm the calibration by recording a confirmation characteristic curve. In the illustrated embodiment, the confirmation characteristic curve corresponds to the cable deceleration curve “Vv = f (t)” (see “6”). During this confirmation, a confirmation characteristic curve (FIG. 3) may be measured and optionally a pressure curve “Pe2 = f (t)” may be measured. When this confirmation characteristic curve matches the calibration reference characteristic curve, the calibration can be validated. In one embodiment of the present invention, the coincidence between the pressure curves “Pe = f (t)” and “Pe2 = f (t)” is also confirmed.

  The diagnostic method includes at least one inspection step for inspecting the braking means. In particular, this inspection step can be carried out in advance in order to confirm the adjustment of the braking that conforms to the prescribed adjustment setting.

  During this inspection step, a simulation operation is performed that simulates the braking that is performed in a transport facility that is operated in a loaded state in a transport facility that is operated in an unloaded state. For this purpose, the braking means are driven in an unloaded state by driving means controlled in a closed loop on the basis of a setting signal constituted by a prerecorded control curve “F = f (t)”. Used for transport equipment. Therefore, in this step, the driving means simulates the load force and the inspection characteristic curve is recorded.

In the embodiment shown in FIG. 4, three test characteristic curves constituted by cable deceleration curves “Vtc = f (t)” (see “3”, “4”, “5”) are shown.
In order to determine whether or not the braking adjustment is suitable, the cable deceleration curve “Vtc = f (t)” (see “3”, “4”, “5”) is the calibration reference characteristic curve “Vec = f ( t) ".

  In FIG. 4, the first curve “3” has a steeper slope than the calibration reference curve “Vec = f (t)”, and shows a state where braking is too strong. The second curve “4” has the same slope as the calibration reference curve “Vec = f (t)” and shows a state in which the braking is accurately adjusted. Finally, the third curve “5” has a gentler slope than the calibration reference curve “Vec = f (t)”, indicating that the braking is too slow. Based on the comparison function of the curves “Vec = f (t)” and “Vtc = f (t)”, the braking means can be adjusted to an accurate setting.

  The inspection step preferably further comprises a recording step for recording a pressure curve “Pt = f (t)” in the braking means. This pressure curve “Pt = f (t)” is compared with the calibration reference pressure curve “Pe = f (t)”. Thus, the braking means is determined by determining whether the deviation value between the curves “Vec = f (t)” and “Vtc = f (t)” is related to the hydraulic or pneumatic control means. Can deepen the diagnosis.

  In an embodiment of the invention, the diagnostic means may further comprise a preliminary inspection of the braking means in a transport facility operating in an unloaded state. To that end, the calibration reference characteristic curve is recorded when the braking means is used in a transport facility operating in an unloaded state in the pre-calibration phase. In the illustrated embodiment, the no-load reference characteristic curve is a deceleration curve “Vev = f (t)”. In the inspection phase, the characteristic curve is recorded when the braking means is used in a transport facility operating in an unloaded state. In this embodiment, the characteristic curve is a deceleration curve “Vtv = f (t)”. In order to detect any inaccurate adjustment of the braking means, the characteristic curves “Vev = f (t)” and “Vtv = f (t)” are compared.

  In the second embodiment (not shown), the characteristic curve indicates the force acting on the cable, or the driving torque, or the characteristics of the driving means, and measures a variable proportional to the force acting on the cable or the driving torque. It may be a measurement curve indicating the value. In this case, the control curve corresponds to a deceleration curve indicating the deceleration of the cable. It should be noted that in this embodiment, it is relatively difficult to interpret the comparison between the calibration reference curve and the inspection characteristic curve.

  In this case, during the calibration phase, the driving means control curve “F = f (t)” is recorded when the braking means is used in a transport facility operating in the loaded state. It should be noted. And during the second step, the braking means is used in the transport equipment driven in the unloaded state by the driving means controlled in a closed loop based on the setting signal constituted by the pre-recorded control curve In doing so, a reference characteristic curve is recorded.

  The diagnostic method of the present invention desirably employs a configuration that can inspect adjustments of various braking means of the transportation equipment such as an electromagnetic brake, an emergency brake, or a service brake. For this purpose, the method can be applied to various braking means by means of deceleration curves “Vec = f (t)”, “Vtc = f (t)”, “Vv = f (t)”, “Vev = f (t) "and" Vtv = f (t) "(see" 1 "," 3 "," 4 "," 5 "and" 6 "), and drive means control curve" F = f (t) " (See “2”). Therefore, the adjustment of each braking means can be inspected separately.

  In order to make an accurate diagnosis of the braking means, the position of the vehicle in the cable must be accurately indexed so that all application of the method requirements of the braking means are carried out with approximately the same load distribution in the cable. Is preferred.

  Furthermore, if the brake means to be tested does not operate in “all-or-nothing” mode, the brake means should be used at the same level in the context of the diagnostic method. You should be careful.

  If the braking means is a means that is controlled by adjusting the force based on the function of the cable deceleration, it is necessary to suspend the adjustment before executing the method of diagnosing the braking means. Become.

  The simulation method of the present invention can also diagnose force adjustment based on a function of cable deceleration. When the driving means is controlled in the closed loop based on the setting signal constituted by the control curve “F = f (t)” that is a deceleration curve, the control curve “Fe = f (t)” recorded in the calibration stage. It is possible to inspect the adjusting device by changing the control curve “F = f (t)” in relation to and monitoring the response of the adjusting device.

The mathematical proof that can confirm the above diagnostic method is as follows.
In the preliminary stage, when the braking means is used in a transport facility that is operating in an unloaded state and “Vec = f (t)” is recorded, the following relationship is obtained.

Fc + Ffe = Mc * αec (a)
Fc: Force generated by a load in a transport facility operating in a loaded state Ffe: Calibration reference braking force M: Mass of cable and vehicle α: Acceleration of cable

Similarly, the following relationship is obtained when the braking means is used in a transport facility operating in an unloaded state.

Fv + Ffe = Mv * αv (b)
Fv: Force generated by the load of the unloaded transport equipment

In the preliminary calibration stage, when the driving means is controlled based on the deceleration curve “Vec = f (t)” (see “1”) as the setting signal, the following relationship is obtained.

Fmot + Fv + Ffe = Mv * αec (c)
Alternatively, Fmot = Mv * αec−Fv−Ffe (c ′)
Fmot: Force generated by the motor

Finally, in the inspection stage, the driving means is controlled based on the control curve “F = f (t)” (see “2”) and the curves “Vtc = f (t)” (“3”, “4”). ”And“ 5 ”) are measured, the following relationship is obtained.

Fmot + Fv−Fft = Mv * αtc (d)

By replacing “Fmot” in the relationship “c ′”, the following relationship is obtained.

Mv * αec−Fv−Ffe−Fv−Fft = Mv * αtc
Mv * αec−Ffe−Fft = Mv * αtc

Therefore, when the curves “Vec = f (t)” and “Vtc = f (t)” are similar, “αec = αtc”. As a result, the braking force of the inspected braking means becomes equal to the calibration reference braking force of the braking means (Fft = Ffe). Therefore, in this case, the braking means is accurately adjusted.
