Definitions

  • the invention relates to a bus-based safety system of an elevator installation and to a method for checking the safety system of an elevator installation.
  • Elevator systems have a safety circuit in which several safety elements, such as safety contacts and switches, are arranged in a series circuit.
  • the contacts monitor, for example, whether a shaft door or the car door is open.
  • the elevator car can only be moved if the safety circuit and thus also all safety contacts integrated in it are closed.
  • Some of the security elements are operated by the doors.
  • Other safety elements such as an override switch, are actuated or triggered by the elevator car.
  • the safety circuit is connected to the drive or the brake unit of an elevator installation in order to interrupt the driving operation if the safety circuit is opened.
  • the safety bus system typically includes a control unit, a safety bus, and one or more bus nodes.
  • a safety system with safety bus is in the application EP01810903.3 described on 18.09.01.
  • the safety bus is used to enable safe and reliable monitoring of the hoistway doors of the lift system.
  • Another solution, which is considered to be the closest prior art, is incorporated in WO 03/024856 A disclosed.
  • a safety bus security system in some of the proposed embodiments, includes at least one bus node, which may, for example, communicate with a security element to query its status. This can provide information about the current state of security elements. Similar to the conventional elevator systems with safety circuit, a reaction can be triggered depending on the condition of the safety element.
  • GB 2 127 603 discloses a security system for an alarm system, comprising a control unit, at least one bus node at least one security element (sensor), and a bus that enables communication between the control unit and the bus node.
  • the bus node has first circuit means and second circuit means.
  • the first circuit means act on the security element with a first analog signal.
  • the second circuit means (amplifier) picks up a second analog signal on the security element. After analog-to-digital conversion, it is made available to the control unit via the bus as digital return information.
  • the bus node includes a test voltage generator which, when activated, generates a test voltage for the safety element.
  • the object of the invention is thus seen to show an improved safety system of the type mentioned, with which the disadvantages of the prior art can be avoided or at least greatly reduced.
  • Fig. 1 shows a first security system 10, which is part of an elevator system.
  • the security system 10 comprises a control unit 11, at least one bus node 13 and a bus 12 in order to enable communication between the control unit 11 and the bus node 13.
  • a security element 16 is indicated which, for example, queries the state of a manhole or car door or which monitors a bar.
  • Security elements are referred to in the context of the present invention, safety-related elements, namely door contacts, bolt contacts, buffer contacts, flap contacts, driving switch (eg on the inspection panel or in the return control), and emergency stop.
  • the bus node 13 has first circuit means 14 and second circuit means 15.
  • the control unit 11 gives the bus node 13 a setpoint value, for example a current intensity or a voltage.
  • the control unit 11 thus acts as a "command generator".
  • the specification of the desired value is carried out by transmitting a digital command or digital information via the bus 12 to the bus node 13.
  • a first analog signal corresponding to the predetermined target value is provided by the first circuit means 14.
  • the security element 16 is acted upon by this first analog signal, as indicated by the arrow 16.1.
  • the second circuit means 15 are arranged and adapted to pick up a second analog signal on the security element 16, as indicated by the arrow 16.2.
  • the bus node 13 processes the second analog signal and provides digital feedback information, which is either transmitted via the bus 12 to the control unit 11, or which is picked up by the control unit 11 via the bus 12 at the bus node 13.
  • the bus node 13 may provide digital diagnostic information.
  • the comparison preferably takes place in the control unit 11 in order to be able to make a reliable and reliable statement about the security element 16.
  • the control unit 11 can thus determine, for example, whether the security element 16 is opened or closed.
  • the bus node 13 It is also possible to perform a qualitative evaluation of the first analog signal when processing the analog signal, wherein the evaluation is not relevant to safety and can therefore be carried out completely or partially by the bus node 13.
  • This qualitative evaluation allows a diagnosis to be made about the qualitative condition of the security element (for example, the wear and / or the functional efficiency of a contact can be assessed). It is particularly advantageous to carry out this diagnosis in the bus node 13 in order to minimize the data traffic on the bus 12 and not to burden the safety-relevant control unit 11 with it.
  • the result of the diagnosis is provided as digital diagnostic information.
  • control unit 11 sets a certain current as the setpoint, which is then impressed in the security element 16, the control unit 11 via the second circuit means 15 and by means of the return information determine whether the corresponding current or, for example, a voltage with correlated to the current was measured.
  • a value pair can be taken from a table.
  • the control unit 11 presets a current of 1A.
  • the circuit means 14 provides a current with a current of 1A. This current flows through the security element 16.
  • a voltage of 5V is measured by the circuit means 15, the circuit means 15 having a resistance of 5 ohms to convert the current into a voltage. From a table, for example, stored in a memory of the bus node 13, it can be seen that a voltage of 5V corresponds to a current of 1A. In this case, comparing the value pair (1A; 5V) has shown that the query chain works.
  • the qualitative comparison (also referred to as diagnosis) is designed so that a certain tolerance is taken into account.
  • the query chain would be considered to work as long as the voltage deviates from the 5V voltage, for example, by less than 0.5 volts. Thus, it can be considered that such inaccuracies and losses are inherent in such a query chain.
  • the tolerance (s) can be absolute or relative.
  • the tolerances can also be variable.
  • a reaction can be initiated. This is done for example by the control unit 11. With a small deviation, a service call can be triggered by the control unit 11. In the event of a greater deviation, this must be interpreted as a "malfunction" and lead, for example, to an emergency stop of the elevator installation.
  • the Fig. 2A and Fig. 2B show a second security system 20, which is part of an elevator installation.
  • the security system 20 comprises a control unit 21, at least one bus node 23 and a bus 22 to enable communication between the control unit 21 and the bus node 23.
  • a switch 26 is shown as a security element sensing, for example, the condition of a manhole or car door, or monitoring a (hoist door) latch.
  • the bus node 23 has first circuit means 24 and second circuit means 25.
  • the first circuit means 24 in the illustrated embodiment comprise a processor 24.1 which can receive digital information over the bus 22 as indicated by the arrow 22.1. There is provided a recorder element 24.2, which provides a "control" signal S S , which is applied to a controllable current source 24.3 and there causes the provision of a current.
  • the recorder element 24.2 may comprise, for example, a digital-to-analogue converter.
  • the processor 24.1 evaluates the digital information to determine which setpoint the control unit 21 has specified and provides the recorder element 24.2 a digital signal D Soll .
  • the current is referred to here as the first signal S 1 .
  • This first signal S 1 is correlated with the "control" signal S S.
  • the circuit means 25.3 in the present example is a converter which converts the current S * 1, which is supplied via the line 26.2, converted into a voltage S 2 .
  • the voltage S 2 is referred to here as the second signal S 2 .

  • the read element 25.2 may comprise, for example, an analog-to-digital converter.
  • the second embodiment is designed so that the bus node 23 performs a diagnosis by a qualitative comparison of the first analog signal S 1 with the second analog signal S 2 .
  • This comparison may, for example, be performed jointly by the processor 25.1, by the processor 24.1, or by both processors 24.1 and 25.1.
  • a comparison operation by only one of the processors 24.1 or 25.1 requires at least one cross-connection between the first circuit means 24 and the second circuit means 25.
  • the result of the comparison is then provided to the control unit 21 as digital diagnostic information. Either the digital diagnostic information can be queried by the control unit 21 at the bus node 23 (pull principle), or the bus node 23 can transmit the digital diagnostic information via the connection 22.2 and the bus 22 to the control unit 21 (push principle).
  • the described qualitative comparison is carried out in addition to the quantitative comparison, which is carried out in the control unit 21 on the basis of digital feedback information.
  • Performing the qualitative comparison in the bus node 23 has the advantage that the bus 22 is not burdened with the transmission of signals, but that in each case only the digital diagnostic information, which in principle represents the result of the qualitative comparison, and the return information for the quantitative Comparison in the control unit 21, is transmitted via the bus 22 to the control unit 21.
  • Another embodiment of the invention is designed so that not only a comparison of the analog signals, but also an evaluation of the second analog signal S2 is made.
  • an evaluation in the sense of a diagnosis
  • the security element is a switch in that the contact resistance is determined.
  • the bounce behavior of a switch can also be evaluated.
  • the resolution must be sufficient because the bounce typically in short Voltage peaks reflected and a change in the bounce can only be shown if a precise evaluation of the voltage peaks.
