METHOD FOR TESTING THE OPERATION OF THE LIFT SYSTEM

The invention relates to a method for testing the operation of an elevator system as defined in the preamble of claim 1.

As a known technique, a device according to US A 3973 648 which monitors elevator groups via a modem connection via a central computer may be mentioned. An elevator group selected by the central computer transmits information about operating, disturbance and alarm events to the computer in a digital format in serial form. The interface between the elevator group and the central computer is a hardware interface, which has a monitoring and mediating function.

15

The disadvantage of the device is that the data is forwarded as a tower interpreted. The central computer will have to interpret the information entered and determine whether the interpretation has resulted in maintenance. Passing up-to-date information to the Central Info-20 requires a long lease of cable and a lot of computer time. A further disadvantage is that the central computer calls the supervised elevator groups. Therefore, data is not collected when they are created, but after a delay depending on the query period. Besides, at least when traffic is low, there are • · 25 events that may not occur at all.

· »·« · • · ♦ · ·

· ** .. Another known technique may be mentioned in US

. * i '· A 4512442 said invention. The present invention tracks events in equipment included in the elevator system. 30 via signals continuously. Each signal to be monitored is • · amplified. If the number of each signal exceeds the number specific to the signal • · * 1 'L then a service request is sent to the service unit. In our invention, the signal to be monitored is activated by an alarm button,. 35 so that the signal-specific time is less than • ♦ ·. ···. after a specified time, and if the car does not respond to a given · ♦ · 2 107726 car call, an alarm signal is sent to the elevator maintenance unit.

When installing the basket hardware, a plurality (about 10) of basket cable strings are required between the elevator car and 5 telecommunication interface units in the engine room for power supply, indicator light control, switch and push button monitoring, and speaker and microphone control. Most, especially old elevators, the basket cable does not have a sufficient number of extra strands. A new basket cable that meets the interface requirements is required.

In the solution according to the invention, only one pair of wires-15 is used for communication between the engine room and the elevator car, along which both the electricity required by the car unit and the control and speech signals are transmitted. The system is highly fault-tolerant and does not require special cables, the threads of an existing basket cable can be used. for data transfer. The elevator remote control system consists of 20 modern / control units, usually located in the engine room, which recognize the press of the elevator car alarm button, call the service station and establish a voice connection between the passenger and service person who performed the alarm.

• · ·: Some units can have multiple lifts • · ί, ϊ.ϊ 25 provided they have a common engine room.

The remote control system is divided into three levels, so that level I = elevator alarm button monitoring and speech connection. ···. 30 Equipment and Level II = Level I + In addition to the Alert Button • · Anti-vandalism filtering, elevator failure and other vital '1' elevator event monitoring system. Level III = Level II + High Level Elevator Control System. The remote control system consists of two subsystems: maintenance. 35 center-based service center equipment and installation «» · • · ·. ···. on-site local equipment in buildings whose lifts are controlled. Communication between the 107726 installation site and the service center equipment is done through the public telephone network. One receiver 20 can serve hundreds of local copies. In the method of the invention, signals indicating abnormal functions generated by the devices of the elevator system and combinations thereof are continuously monitored and each signal / signal combination to be monitored is recorded. The invention is characterized by detecting whether there is a change in the signal / signal combination state during a characteristic time 10 of the signal and issuing a basket call to the elevator if the specified time has elapsed and tracking the basket to the given basket call.

In the following, the invention will be described in more detail by means of the pre-15 characters with reference to the accompanying drawings, in which:

When this is done, normal operation • · ·. ***. the program can be started. Local equipment is maintained and maintained by normal elevator service personnel. 6 107726 expensive equipment should be nearly maintenance free, except for the following checks: - Testing the condition of the battery and replacing the battery if necessary - Controlling the transmission (data and audio) by testing 5 push buttons on each elevator car.

-Visual inspection of the equipment.

The receiver 20 has its internal uninterruptible power supply, which allows 8 hours of operation without mains supply. The receiver 20 is provided with a switch and a lamp 10 which indicates whether the receiver 20 of the service center is unmanned.

Receiver 20 has automatic testing features and corresponding visual indicators for: - mains or battery supply 15 - battery low battery - phone line failure - PC not connected - log printer not connected 20 In standby mode, all incoming calls are received and received 14.

The system also has a function that triggers a callback from the local hardware. When detecting a call from a specific local hardware, it is possible to select from a variety of 5 commands: (a) status information, (b) maintenance / testing purposes, (c) setting / configuring all local hardware parameters, (d) establishing voice communication, (e) I / O unit outputs for remote control.

Remote Monitoring System Functions:

Each lift has its own identity, which is indicated with each call. From the local hardware 15, a message can be sent to a plurality of service centers: a main service center, at least two backup service centers, a programming service center and also a regular telephone. The primary function of the remote monitoring system is to report an emergency. An emergency is triggered by passengers trapped on the moon by using the alarm button in the elevator. The system establishes a voice connection between trapped passengers and a service center attendant.

• · ί · * Another function of the system is to notify the elevator of • * · V: malfunctions or maintenance. If a service visit is not required • · 25 immediately, the need for service will be indicated with the routine call ···. This feature is part of the Tier II hardware. In order to maintain a high level of safety at each installation site, the system • performs an automatic self-test and reports any malfunctions. Self-Test · * ·. 30 The message includes a battery check • ·. ···. and lack of mains power.

• · * '* In the system, each local hardware sends regular routine calls to a service center. With this regular routine call ... · ·, the service center will monitor the location. 35 additional hardware. If the Service Center does not receive regular • · · • · ·. ·· *. routine call, it can arrange a service visit to the • • installation site. This regular connection is also used to signal early maintenance needs of 107726 δ and to transfer certain parameters from the service center to the local hardware. The service center may call the installation site hardware to establish a data connection for parameter setting and / or data collection from the installation. A voice connection can also be established.

A copy call is a copy of a message previously reported to another service center. The users of the local equipment 10 are trapped passengers and lift maintenance engineers who use the installation site equipment to service the elevators. Service center equipment users are service center operators or operators. Local hardware operation: 15 Automatic dialing

For each type of call, base unit 5 establishes a telephone connection to a service center according to a telephone number list. The first part of the message sent by the local hardware comprises the hardware identification code and the call type. Invitation type 20 determines what information is sent. It should be possible to send multiple messages without interrupting the telephone connection. The Service Center will then respond, depending on the type of call.

• ·

Examples of call types: • ·· '. · · 1st alarm call with voice connection • ·' .V 25 2nd technical / system fault call: ***: 3rd maintenance call ··· 4th routine call 5th call • · · 6th copy call · ··. 30 If a routine call is possible, 1 service request call1 will be • reported at the next routine call. If the call is an * * alarm call or a technical call, the service center will answer whether it is manned or not. If it is unmanned, ··· the local hardware will call the next telephone list. 35 mer. If it is occupied, the complete alarm message will be sent to · ·, ···. hetetään. In the event of an alarm call, a voice connection is also • created. The voice part of the alarm call can also be sent to a normal 9 107726 finish phone. There are two ways to do this: 1) First call the service center where the message contains the phone number to use, or 2) First call the standard phone and after the message is sent to 5 service centers. Other types of calls are recorded by the service center equipment and processed by the operator either immediately or later. If the purpose of the callback is to connect to a service center that is not on the phone number list, the new callback phone number must first be transferred from the service center to the local hardware before the new callback can be initiated. Usually, messages between the service center and local equipment are equipped with a handshake to ensure that no message is lost. All messages are error protected to ensure correct data transmission.

Starting an alarm call

The normal way to trigger an alarm is to press the alarm button in the elevator car. To prevent false alarms, the alarm button must be pressed for a certain period of time before the 20 alarm rings. This time interval is called "filter time". If the alarm button is pressed and stops pressing again for a short time, there will be • ·! · * Accumulated. If the button is pressed for longer than "filter time" ··· \ * *, the accumulated value will be reset. Time filtering is • ·

To enable alarm call '· * even when the basket is stopped in normal position · · · · · · · · · · · · · · · · "interval.

e. . * · 35 (b) with automatic basket calls (I / O unit) outputs ···. ·· *. elevator controllers. One or two outputs ♦ ♦ t ··· can be configured for automatic basket calls. When the alarm button on the 10 107726 basket is activated, the basket outputs are first activated sequentially to see if it is possible to move the basket to another position. If the elevator car does not respond by moving and 5 opening the door, the alarm will be triggered automatically. This automatic basket call function is configured according to national regulations.

In the Level II system, a special "voice test 10 ring" is triggered if the "Service Engineer on site" status is valid.

Technical Alert and Service Call

An elevator failure, internal error condition, or internal counters or timers may trigger the call. In Tier I system 15, technical alarm calls are triggered by internal fault conditions including 'low battery voltage', 'no mains supply during (programmable) cycle' and 'no response from configured basket units'. In a Level II system, technical alarm calls can also be triggered using monitoring functions based on signals from the elevator controller connected to the I / O unit. Such functions can be configured individually for each elevator. The states / conditions are programmed using combinations of soft types (defined behavior of a certain type of input • · ·. 25) and logical functions. Configuration options also include • · * • *. ·· 'timer functions and latch memory. Each input can be: ** programmed with some type of software to produce the desired response. Each input can also be assigned a text string for ease of recognition.

: ***: One special feature might be "automatic basket • • ·: ***:". One or two outputs are configured and connected · «» *. the elevator controller. When "auto basket call" is activated, • · · ** ”basket call outputs are activated sequentially to see if it is possible to move the basket to another position. This function could also be remotely controlled from a service center.

• · · • · t · • · 11 107726

The timers can be programmed for a time interval from seconds to hours. In the event of a technical failure, it should be possible to delay the start of the technical alarm call. If the basket is taken into use after the technical fault has been reported, 5 cancellation notifications must be sent immediately.

In Level II hardware, service calls are triggered by elevator counters that calculate 1) the number of starts, 2) the number of door closures, and 3) the total travel time. If there is a platform drive. available, a counter could also be configured for each of the 10 floor doors.

The hardware may be configured to provide a copy call to the main service center for each message sent to the emergency service center. The telephone number list comprises at least 6 telephone numbers to be used for different types of call 15.

- Phone number "A" for area main service center - Phone number "B" and "C" are backup numbers "A": lie - Phone number "D" is for programming center and it could be the same as "A" - Phone number "E" is for routine calls - Telephone number "F" is a normal telephone number .... Each telephone number can contain up to 24 digits, • · '..1 including dialing code, eg Wait for dialing ii · *. 25 tones', 'Change voice to hair dial' or 'switch to pulsating'.

• · * ··· 'Automatic time adjustment is included in routine calls with the automatic time / date setting function.

• · · · * 1) - If the service center says that it is unmanned, then dial the next number in series 30 - If "service center is busy", try N times the same number ·· · · ·: ***. After N failed attempts, go to the following number.

• ♦ '* ·. · * - 35 If "communicating with a service center", try v!. N times to the same phone number.

: ***: * 2) - Normally the callback goes to the programming center, but 12 107726, when the emergency alarm has not yet been acknowledged and a callback trigger is detected, the local hardware sends a new call. This function is intended to ensure that the message sent by the service center is accessible to the 5 trapped passengers.

* 3) - If "Copy Call" is selected, a copy of the message sent to the Emergency Service Center will be sent (wherever possible) to A.

* 4) - If "Service Center is busy", try again in M minutes 10. The telephone number of a routine call can be configured to use a special number. The purpose of this configuration is to ensure that telephone line A (at the same service center) is available for emergency calls.

* 5) -15 If routine calling is allowed, low-priority service calls will be reported at the next routine call.

* 6) - It must be possible to make a "voice only" call to a normal phone.

20 The above call order and functions may vary due to local regulations. Internal phone number checking filters out specific numbers, such as 000 or 999.

• · · i ·· ·· • · 13 107726

The automatic routine call is executed at programmed intervals. This function can be set on / off. Service information is automatically sent when a routine call occurs. The routine call event must be as short as possible in order to minimize the load on the receivers in the service center and the communication costs. All programmable functions have default values to minimize the unique configuration of local hardware.

10 All time-dependent events are recorded in the event log, which registers them with time and date. Registered information can be read on site or from a service center. Transaction log event information is located in the FIFO (First-in-first-Out) buffer. Memory should be reserved for at least 50 events. All types of calls to the service center are recorded in the event log. Similarly, events related to base unit 5, i.e. telephone line failure, 2-wire bus failure, and base unit 5 self-test failures are recorded. Apiece. For 20 events, the event log has a status field that indicates that the event has been successfully reported (reported), has not been reported, or has not been reported. reported. The same event that occurs at short intervals must not · · fill the event logs, but must either “count • · * · * / 25 up” or remain unregistered until the previous event has been acknowledged. The status register maintains all status signals, such as 'emergency call', 'service engineer on site1', '', '', '', '' lift off '', or 1 maintenance request1.

• · · · All faults / alarms / service needs must be 30 'acknowledged1 after service or inspection has been completed. This status: ***: The registry also contains event counter values from the last * · · · service visit. Each call is accompanied by a · · * message informing you of the elevator ID code, the address and the location of the car. Each lift has its own programmable ID • · * ·· / * 35 and address information. Up to 20 characters for ID information, up to 40 characters for address. Alternatively, the address part of the message may be omitted. The message also contains the reason for the call.

14 107726

It also includes the number of attempts needed to connect to the receiving receiver 20. The position of the basket is indicated by the digital inputs, if any (available for Level II 5 systems only). All local hardware parameters can also be programmed / configured at the factory and downloaded from the service center PC via the receiver or programmed locally. When programming, whether locally or 10 remotely, you must use a password to access the configuration tables. The password can be changed by authorized personnel. The Counter Trigger Trigger function is triggered when a call is detected. Uninterruptible power supply should be sufficient for at least 8 hours of use. The on-site accessory 15 can be expanded to handle up to 8 lift carts.

Passengers trapped in an elevator car are constantly kept aware of the progress of the call by means of an emergency call to avoid panic. The emergency call in progress is indicated by 20 ALARM lights in the calling elevator car and sound from the loudspeaker, which can, for example, mimic the telephone dial tones. Speech mode indication in the body unit when a call to a service center or a standard telephone is established, this • · * ..! the light comes on to indicate that 'the basket is being watched' or • · t '* 25' the basket is being listened to 'and that the microphone is connected. • During the radio transmission mode, the lamp is off.

• · ** y 35 When the Service Center Operator selects the radio voice communication feature, the voice message is transmitted over the radio to all lift platforms which are in emergency call.

··· 15 107726

An open protocol is used for communication between the base unit 5 and the service center in order to achieve the best possible integration.

Communication over a 2-wire line (between base unit and I / O unit 15) must use an open protocol to add new functionality to levels II and III.

All commands can also be given over the telephone line. The optional keypad / display can provide up to 10 commands at the installation site.
