摘要: The invention relates to an apparatus for regulating the speed of an a.c. elevator motor (10) by means of a frequency converter (8) consisting of a rectifier bridge (12) and an inverter bridge (14) with an intermediate circuit between them. The frequency of the frequency converter is adjusted until it corresponds to a frequency reference (f.sub.ref) corresponding to the speed reference (v.sub.ref,v.sub.ref ') of the motor. The velocity of the motor (v.sub.real) is measured to form a speed feedback signal. According to the invention, the apparatus has elements (24,26) for correcting the speed reference (v.sub.ref) on the basis of the change occurring in the voltage (U.sub.c) of the intermediate circuit.

The elevator system includes at least an elevator car, elevator ropes, an elevator motor, a traction sheave and at least two holding brakes, which holding brakes are arranged to prevent movement of the elevator car when the elevator is stopped. According to the invention the first holding brake is engaged at the end of an elevator run, and the other holding brakes are engaged with a delay. When one holding brake is engaged, the state of motion of the elevator and any slipping of the brake is monitored. If the brake is detected as slipping, a procedure for preventing a hazardous situation is performed.

摘要: A procedure for adjusting the stopping of an elevator as accurately as possible on desired level with the aid of the deceleration instruction (DR). From the elevator's deceleration instruction (DR) a sample is taken at the beginning and at the end of deceleration, these are compared with each other and the linearity of deceleration is adjusted on the basis of the result obtained. The invention also concerns an elevator deceleration measuring circuit for carrying out the procedure. The measuring circuit, connected to the deceleration instruction (DR) of the elevator, comprises a display unit such as for instance two light-emitting diodes (D4,D5) by which the result can be ascertained if the deceleration instruction is increasing or decreasing.

摘要: A control circuit for use with an electronic guard strip for preventing collision of the strip with a moving object. A control such as a relay, is connected to at least one antenna, which antenna forms a capacitor together with a base in its ambiance. A voltage generator conducts an alternating voltage to the antenna. The control and the antenna are connected in circuit relation to an amplifier. A change of voltage arising from any capacitive protuberation in the antenna is conducted to the control. The voltage from the amplifier is conducted through a rectifier to another amplifier that is connected so as to have its direct current gain as +1, but which amplifies any change of voltage occurring in the d.c. voltage input to a multiple and which further acts upon the control through a comparator.

摘要: The invention relates to a method for monitoring the condition of the door of an elevator and determining its need for maintenance, the door comprising a door mechanism, door panels and a door operator. The signals (10) of the control system of a door in good condition are measured and a set of characteristics descriptive of the operation of the door is generated from them. The signals (10) of the door control system are measured the operation during the opening and closing movements of the door is divided into stages according to which parts of the door are functioning at each stage. From the measured signals (10), a set of characteristics descriptive of the operation of the door is generated. The set of characteristics thus generated is compared to the set of characteristics for a normal operating condition stored in memory, at least in one stage of operation. Based on the comparison of the two sets of characteristics, a diagnosis is performed to determine where and how the operation of the door and its components deviates from normal operation, and the result of the diagnosis is utilized to establish the need for servicing and a servicing date.

摘要: An elevator speed control system permitting rotation of the motor with short-circuited rotor at full speed, wherein the thyristors controlling said motor permit the motor to rotate at full speed and when the elevator is running in the lighter direction, operation of the motor as generator at an over-synchronous speed. The system comprises a control unit assembled of components known in themselves in the art by which the instruction value is increased considerably past the actual value, whereby the motor with short-circuited rotor is left to rotate at full speed, and that on commencing retardation the instruction value is dropped directly to be consistent with the actual value.
