Abstract

Example embodiments relate to a method and arrangement for monitoring the operating condition of a transport system. In one or more example embodiments, the method includes measuring a value associated with operation of a reader device, the reader device configured to transmit a reading signal to read an identifier, if the identifier is situated within range of the reading signal, and detecting a presence of a functional nonconformance in the operation of the reader device based on the value associated with operation of the reader device.

Claims

1. A method for monitoring a transport system, the method comprising:

measuring a value associated with an operation of a reader device, the reader device configured to perform a transmit operation to transmit a reading signal to read an identifier, if the identifier is situated within range of the reading signal, and a receipt operation to receive a pulse pattern from the identifier in response to the reading signal, the operation including one or more of the transmit operation and the receipt operation; and

detecting a presence of a functional nonconformance in the operation of the reader device based on the value associated with operation of the reader device.

2. The method according to claim 1, further comprising:

generating a monitoring signal indicating the functional nonconformance of the reader device, if the detecting detects the presence of the functional nonconformance of the reader device.

3. The method according to claim 2, wherein

the measuring includes instructing the reader device to generate the reading signal to read the identifier, and measuring the reading signal;

and

the detecting the presence of the functional nonconformance of the reader device includes detecting the presence of the functional nonconformance, if a level of the reading signal deviates from an acceptable level.

4. The method according to claim 1, further comprising:

reading, by the reader device, a readable marking of a test identifier.

5. The method according to claim 4, wherein the reading device reads the test identifier after the reading device temporarily uncovers the test identifier.

6. The method according to claim 4, wherein the detecting the presence of the functional nonconformance of the reader device comprises:

reading, from a memory device, an acceptable level of the reading signal associated with the test identifier, and

detecting the presence of the functional nonconformance, if a level of the reading signal associated with the readable marking of the test identifier deviates from the acceptable level.

7. A monitoring arrangement for monitoring an operating condition of a reader device, the reader device being configured perform a transmit operation to transmit a reading signal to read an identifier, if the identifier is situated within range of the reading signal associated with the reader device, and to perform a receipt operation to receive a pulse pattern from the identifier in response to the reading signal, wherein the monitoring arrangement comprises:

a measuring device configured to measure a value associated with an operation of the reader device, and to generate measuring data based thereon, the operation including one or more of the transmit operation and the receipt operation; and

a monitoring element configured to determine the operating condition of the reader device based on the measuring data.

8. The monitoring arrangement according to claim 7, wherein the monitoring element is configured to generate a monitoring signal indicating a functional nonconformance of the reader device, if the monitoring element detects a presence of the functional nonconformance in the operating condition.

9. The monitoring arrangement according to claim 7, wherein the measuring device is configured to generate the measuring data by measuring a reading signal transmitted by a transmitter associated with the reader device, and

the monitoring element is configured to determine the operating condition of the reader device based on the measuring data received from the measuring device.

10. The monitoring arrangement according to claim 7, wherein

the monitoring element is configured to determine the operating condition of the reader device based on a result of the reading device reading a readable marking of a test identifier.

11. The monitoring arrangement according to claim 10, wherein the readable marking of the test identifier is configured to be selectively uncovered by the reader device.

12. The monitoring arrangement according to claim 10, wherein the monitoring element is configured to,

compare the result of reading the readable marking to one or more monitoring criteria, and

generate a monitoring signal indicating a functional nonconformance of the reader device, if the result of reading the readable marking does not fulfill the one or more monitoring criteria.

13. The monitoring arrangement according to claim 10, wherein the one or more monitoring criteria include (i) a failure to read the readable marking of the test identifier, (ii) an absence of data associated reading the readable marking of the test identifier, and (iii) a deviation between a reference value and a reading of the readable marking.

14. A transport system, comprising:

a reader device configured to read an identifier, if the identifier is situated within range of a reading signal of the reader device; and

the monitoring arrangement according to claim 7, the monitoring arrangement configured to monitor the operating condition of the reader device.

15. The transport system according to claim 14, wherein

the transport system is an elevator system, the elevator system including an elevator car configured to move along guide rails in an elevator hoistway, and

the reader device configured to move in the elevator hoistway along with the elevator car.

16. The transport system according to claim 15, wherein the reader device configured to read a readable marking associated with an identifier after the elevator car has arrived at the identifier in an individualized reading point in the elevator hoistway.

17. A Radio-frequency identification (RFID) reader device configured to read RFID identifiers, the RFID identifiers including first RFID identifiers arranged in an elevator hoistway, the RFID reader device comprising:

a board having a second RFID identifier of the RFID identifiers attached thereto;

an antenna configured to transmit a reading signal to active one of the RFID identifiers in proximity thereto, and to receive a pulse pattern from the one of the RFID identifiers in response to the reading signal, the reading signal being a wirelessly-propagating electromagnetic radio-frequency signal, and

a processor configured to,

measure a value associated with reading the second RFID identifier, and

detect a presence of a functional nonconformance in the RFID reader device based on the value associated with reading the second RFID identifier.

18. The RFID reader device of claim 17, wherein the processor is configured to,

read, from a memory device, an acceptable value associated with reading the second RFID identifier, and

generate a monitoring signal indicating the presence of the functional nonconformance in the RFID reader device, if the value associated with reading the second RFID identifier deviates from the acceptable value.

19. The RFID reader device of claim 17, wherein the value is associated with one of (i) the pulse pattern indicative of a marking associated with the second RFID identifier read by the RFID reader device, and (ii) a voltage of the antenna when transmitting the reading signal.
