Definitions

  • the present invention relates to a safety device for monitoring a movable element, as for example from the document US Pat. No. 6,170,614 B1 is known.
  • a microprocessor interacts with sensors, detectors and safety devices present on the elevator installation. From the position measuring system, the microprocessor receives accurate information regarding the current position of the elevator car in the shaft. On the basis of these continuously obtained position values, a software calculates the actual speed and compares it with the intended setpoint speed, which it reads out from a table stored in a ROM on the basis of the position information. The setpoint speed is stored in the table depending on the path or the position. If the deviation of the actual speed from the target speed exceeds a certain value, the microprocessor triggers a braking operation.
  • the operation and the construction of the safety device should be more comfortable or easier.
  • the shortest possible response time and precise triggering of the safety device should be realized. Due to the increased safety of the monitored systems also an improved design options of the systems should be realized.
  • the safety device is characterized in particular in that it contains a distance determination unit, a speed determination unit and an intelligent comparison device, the intelligent comparison device having a memory for storing a maximum permissible speed and at least one reference position (distance to the target of the movable element) with in particular assigned intermediate speed when the reference position has been reached, the distance determining unit notifies the comparison device which checks whether the reference position has a maximum permissible intermediate speed and, if so, compares it with the actual speed detected by the speed determination unit at that time and if the intermediate speed is exceeded , the trip unit causes to deliver an electronic trigger signal, and wherein the intelligent comparison device continuously compares the maximum permissible speed with the actual speed independently of reference positions and, if the maximum permissible speed is exceeded, also triggers the tripping unit to emit an electronic trigger signal for triggering a braking device. For several reference positions, these are processed according to the size of their distance from the target.
  • the distance-dependent speed limit makes it possible not only to monitor a limiting speed but also to monitor a large number of speeds and even course curves depending on the destination. This leads to a so-called.
  • Mehrstuftechnik the safety device which opens up a variety of additional possibilities, such as the distance limitation to another moving object in the shaft, a targeted test release at low speeds or loads, etc. Also, only one system for all Functions and speed ranges necessary.
  • a more targeted monitoring of the limiting speed in the acceleration and braking phase can be made, which improves the operation and structure of the entire system and facilitates, for. B. in terms of lower requirements for additional buffer zones in a hoistway.
  • the elevator guidelines in a pit provide buffering facilities. These must be designed in such a way that in the event of a malfunction the cab can drive on unrestrainedly at nominal speed without being damaged.
  • the buffers can be shortened to a standard size. Shaft pit and shaft head are correspondingly smaller, the static requirements reduced.
  • An additional reduced second limiting speed requires a speed limiter or safety device operating at least in two stages, which automatically switches over to the lower speed when the car enters the shaft end area and has reached a defined distance to the shaft end.
  • position-controlled multistage not only allows fixed speeds, e.g. to monitor the rated speed, but also braking and acceleration phases according to the pre-calculated path-speed characteristics and to operate a braking device in case of deviations, preferably first the service brake and a negative result a short time later an emergency brake such.
  • B. a safety brake a safety brake.
  • the corresponding reference data from the normal path-speed profile of the moving element to be monitored, for example an elevator car can be copied by the elevator control into the memory of the safety device or entered separately into it.
  • the security device can also current data, for example, from an external information system, such. B. a shaft information system in elevator systems, are provided.
  • the safety device For this purpose, it is advantageous to continue to equip the safety device with a data transmitting and / or receiving unit.
  • This makes it possible, for example, to drive several cabins in a shaft, each of which is assigned its own safety device.
  • the data of each security device is continuously exchanged wirelessly or by wire with the neighboring cabin.
  • the safety device thus recognizes its own position and that of the neighboring cabin. It continuously determines the distance to this. If the determined distance falls below a predetermined, stored reference value, the speed assigned to this reference value is additionally activated and compared with the actual speed detected by the safety device. When the reference speed is exceeded at the time of the undershot reference distance, the safety device triggers.
  • This adaptive behavior ensures that several cabins move optimally in a shaft, for example also on each other can close, and the safety device only intervenes when safety driving conditions occur.
  • the invention can also be used to automatically and gently perform the still required catch and buffer tests in a reduced speed range and to record the result in a memory.
  • the multistage of the safety device can e.g. be achieved in that the previous, rope-driven, single-stage mechanical release is maintained and supplemented or retrofitted with an electronic module or an electronic distance and speed limiter unit.
  • the known one-stage mechanical speed limiters have a centrifugal force-controlled mechanical release and, in the case of a combination with an electronic speed limiter unit, are intended to monitor an absolute maximum speed. That is, the mechanical speed limiter unit of a multi-stage combined distance and speed limiter is mainly intended for emergency operation, thus significantly increasing the safety of the system.
  • the safety-relevant data of the monitored by the safety device movable element, such as the elevator, as well as the data in case of failure, such as release speed, trip time and braking delay after triggering the braking device can be recorded in the memory provided in the safety device and are available for analysis and reconstruction all operations available.
  • the data may also be saved in a separate, encapsulated and sealed memory device and stored at a defined time interval, e.g. be overwritten again every 10 minutes.
  • the safety device has a distance and speed determination unit.
  • the realization of these units can be done in various ways, eg. B. separately or combined.
  • a pulse counter may be provided which detects codes on a Kodierusion, which is driven by a rope, the traction sheave or a friction wheel on the element to be monitored.
  • radar and / or laser sensors for the contact-free determination of distance and speed.
  • a pyrotechnic actuator is provided according to the invention as part of the trip unit of the speed limiter, the explosive charge is ignited by an electronic trip signal of the trip unit.
  • this pyrotechnic actuator may e.g. consist of a cylinder in which a movable pulling or pressure piston is arranged, which via a linkage or a flexible connection with the braking device, e.g. a catch brake is connected.
  • the braking device e.g. a catch brake is connected.
  • FIG. 1 shows a partially sectioned side view of a security device 1 according to the invention, which is composed of a series of functional units, which are realized with the following units. These include: An encoder disc 10 with pulse counter and direction indicator, an electronic control unit 2 equipped with microprocessor, memory, a virtual device, digital clock, a battery-buffered power supply, output units A with serial and parallel outputs, input units E with serial and parallel inputs, and a plugged bombarded Additional memory 13.
  • an actuator 3 in this example, pyrotechnic principle, for the mechanical actuation of the brake. Pulse, electronic control unit 2 and actuator 3 can also be constructed spatially separated be and by a wired or wireless connection z. B. radio linked together.
  • a simplified process of limiting only one maximum speed is as follows: If the electrical control unit 2 determines when comparing the determined actual speed with the maximum speed stored in the memory 13 that the maximum speed is exceeded, an output unit A of the electronic control unit 2 sends the trigger signal of the tripping unit via the line 12 to the igniter 8 of the pyrotechnic actuator 3, whereby a braking of the safety device or the associated elevator car is caused.
  • the functional units include a distance, a speed detection unit, an intelligent comparison device and a trip unit.
  • the components used by the speed determination unit further comprise a friction wheel 9, which is pressed by spring force against a guide rail 11 and on which a coding disk 10 is mounted.
  • a pulse counter and the digital clock which are arranged in the electric control unit 2
  • the speed of the speed limiter which is arranged for example on an elevator car, can be determined during a rotation of the coding disc 10.
  • the distance determination unit uses in principle the same components as the speed determination unit and is executed in the embodiment shown at the same time as a position detection unit. It determines the position of the car in the hoistway, the distance to the fixed or moving target and a desired distance to the destination. It requires additional exact reference points z. B. at the beginning of the shaft and shaft end in the form of sensors, contacts, or magnetic switches to the arrival of the cabin on Final destination to the control unit 2 to signal. These end points P0 can be supplemented by further intermediate destination points P1-n, eg for the stops in the shaft.
  • the distance determining unit now measures at the beginning of operation with the pulse counter in a learning drive from P0 to P0 the shaft in its total distance and with all existing intermediate distances and sets these reference lines, marked in the memory. If the car reaches P0 after the learning run or during subsequent operation, the pulse counter is reset to 0.
  • this call is sent to the elevator control and parallel to the distance determination unit.
  • the latter then reads out the corresponding reference distance P0 - floor 2 stored in the learning run, and subtracts the distance measured by the pulse counter when the car starts to move.
  • the distance traveled results in the position of the car relative to the beginning of the pit and the remaining distance the distance to the current destination.
  • the distance or position-learning unit knows at any time the position of the car in the shaft and the remaining distance to the destination. If a direction reversal occurs, this is recognized by the direction indicator and the path pulses are provided with the sign corresponding to the direction. If 2 cabins move independently of each other in the shaft, each cab receives the position, direction of travel and speed wirelessly or by wire from the neighboring cabin's position determination and speed calculation unit and continuously calculates the distance to the neighboring mobile destination.
  • the intelligent comparison device keeps speed setpoints for distances in the memory which it reads out from the memory as a function of the predefined destination by means of a software component and compares them with the actual values supplied to the distance and speed determination unit.
  • Predetermined setpoints are z. B. a distance 1-n, to a destination x, with an associated reference speed y.
  • the validity period of the reference speed can in turn be defined as point or distance.
  • the comparison unit If the comparison unit receives a destination, it looks in memory to see if there is a distance with or without speed. The setpoint distance is compared with the current distance to the destination; if the distances are the same, an additional adjustment of the speed setpoint with the current actual speed takes place. If the setpoint speed is exceeded, a trip signal is generated. If the comparison unit receives a destination to a mobile object that moves in the opposite direction, it doubles the stored nominal distance.
  • the triggering and data transmission and reception unit includes a plurality of inputs processing control information and a plurality of outputs connected to the actuators of the brakes.
  • a software component assigns the trigger pulses of the comparison unit to the correct actuator in the correct time sequence.
  • Control information is eg the actuation of the actuator, the direction of travel and the speed of the car. If a pyrotechnic actuator 3 receives an ignition pulse via the line 12 and the actuator 3 does not acknowledge this within a time interval, a second ignition pulse is automatically sent on a further parallel output. Due to the current direction of travel, the output unit assigns the trigger pulse of an upward or downward brake. In the case of brakes which are arranged in series, the tripping unit ignites, in accordance with the current speed, eg one or two brakes one after the other.
  • the pyrotechnic actuator 3 consists of a cylinder 4 and a movable piston 5 in the cylinder, which is connected via a linkage or flexible connection 7 with the brake device, not shown. If the trigger signal is transmitted to the igniter 8 by the electrical control unit 2, the explosive charge in the igniter is ignited and the piston 5 is moved accordingly in the cylinder 4.
  • a preferably provided on the pyrotechnic actuator 3 sensor detects the operation of the pyrotechnic actuator 3 and reports them back to the electronic control unit 2.
  • the trip unit of the electrical control unit 2 sends ignition signals at defined time intervals until the actuation confirmation has been transmitted by the pyrotechnic actuator.
  • the number of ignition commands that have taken place and the feedback of the sensor can be stored in an additional memory or a storage area of the memory 13.
  • the ignition status can also be transmitted to the elevator control and the elevator is for example as long disturbed until the number of ignition commands are reset to zero in a renewal of the spent ignition charges.
  • FIG. 2 shows in a similar representation as the FIG. 1 A further embodiment of a safety device 100 according to the invention.
  • the safety device 100 differs from the safety device 1 of the preceding embodiment in that it has a multi-stage combination, in particular a two-stage combination, whereby one stage of the safety device 100 is realized by a conventional mechanical speed limiter unit.
  • Multi-step means in this context that not only a maximum speed can be monitored, but several different, especially graded after the deployment speeds can be monitored. While this is the case in the previous embodiment, in FIG.
  • the mechanical speed limiting unit of the safety device 100 comprises a cable-driven disk 125 in a known construction. A further polygonal one is connected to this Slice 124 grown. In turn, a rocker 120 is mounted above this. The one leg of the rocker 120 terminates in a roller 128, which is pressed with an adjustable spring 121 to the polygonal disk 124. The other end of the rocker 120 terminates in a pawl 122.
