The sensor monitors the environment of the machine room 1, and the switch transmits a signal to the control panel 2 when an abnormality is found in the environment of the machine room 1. In FIG. 1, two machine room sensors and two switches 10 are provided, one of which is a sensor and the other is a switch. However, the machine room sensor and the switch 10 are not limited to the form shown in FIG.

  Regarding the hoistway sensor and the switch 11, the hoistway sensor and the switches 11a and 11b are devices in which the car 5 goes too far above the top floor, and the hoistway sensor and the switches 11c and 11d are the car 5 from the bottom floor. It is a device that prevents too much going down.

  When the car 5 is moving up the hoistway 4, when the hoistway sensor and the switch 11b react, a warning signal is transmitted to the control panel side control device 3 via the transmission path (wire A). When the car 5 further rises and the hoistway sensor and the switch 11a react, a stop signal is transmitted to the control panel side control device 3 via the transmission path (wired A), and the traveling of the car 5 is stopped. . This prevents the car 5 from going too far above the top floor.

  When the car 5 is descending the hoistway 4 and the hoistway sensor and the switch 11c react, a warning signal is transmitted to the control panel side control device 3 via the transmission path (wire A). When the car 5 further descends and the hoistway sensor and the switch 11d react, a stop signal is transmitted to the control panel side control device 3 via the transmission path (wired A), and the traveling of the car 5 is stopped. .

When receiving the landing signal from the landing switch 13, the car-side control device 6 performs control such as opening the car 5. For example, when a sensor (not shown) is provided for each floor, the landing switch 13 receives a signal from the sensor on the floor and determines the landing.

(Flowchart of the first embodiment)
FIG. 2 is a flowchart when the wireless transmission device 8 of the elevator control system according to the first embodiment is normal (normal time).

  When the wireless transmission device 8 is normal, the control panel side control device 3 determines whether there is any abnormality in the state of the machine room sensor and the switch 10 via the transmission path (wired B) (step S100).

  If there is no abnormality in the state of the machine room sensor and the switch 10 (YES in step S100), the control panel side control device 3 has no abnormality in the state of the hoistway sensor and the switch 11 via the transmission path (wired A). Is determined (step S101).

  If there is no abnormality in the state of the hoistway sensor and the switch 11 (YES in step S101), the control panel side control device 3 connects the wireless transmission device 8 (control panel side wireless transmission device 8a, car side wireless transmission device 8b). Then, it is determined whether there are any abnormalities in the state of the car sensor and the switch 12 (step S102).

  If there is no abnormality in the state of the car sensor and the switch 12 (YES in step S102), the control panel side control device 3 determines that the elevator can travel and performs normal traveling (step S103). The normal traveling is, for example, raising / lowering control of the car 5 by the control panel side control device 3 or door opening control of the car 5 by the car side control device 6.

  When there is an abnormality in the state of the machine room sensor and the switch 10 (NO in step S100), when there is an abnormality in the state of the hoistway sensor and the switch 11 (NO in step S101), or the state of the car sensor and the switch 12 If there is an abnormality (NO in step S102), the elevator control system again determines whether there is an abnormality in these sensors and switches (step S100 to step S102). In this case, there may be a failure or malfunction in the elevator operation system. Note that the elevator control system according to the present embodiment may perform re-determination after stopping the car 5 or landing on the nearest floor before determining abnormality again.

  FIG. 3 is a flowchart when the radio transmission device 8 of the elevator control system according to the first embodiment fails.

This embodiment, in the determination of failure in the wireless transmission device 8, and sends a test signal from the cage-side radio transmission device 8b to the control panel side wireless transmission device 8a, the car-side radio transmission from the control panel side wireless transmission device 8a A test signal is transmitted to the device 8b.

If the control panel side control device 3 confirms the reception of the test signal by the control panel side wireless transmission device 8a, to confirm the receipt of the test signal by the car-side radio transmission device 8b ride is car-side controller 6, radio transmission The apparatus 8 determines that it is normal, and performs the normal flow (FIG. 2).

If the control panel side control device 3 has not confirmed the reception of the test signal by the control panel side wireless transmission device 8a is at least one of the control panel side wireless transmission device 8a or cage-side radio transmission device 8b has failed Therefore, a failure of the wireless transmission device 8 is detected (step S200). For the case where the car-side controller 6 has not confirmed the reception of the test signal by the car-side radio transmission device 8b ride also at least one is a failure of the control panel side wireless transmission device 8a or cage-side radio transmission device 8b Therefore, a failure of the wireless transmission device 8 is detected (step S200).

  When the control panel side control device 3 detects a failure of the radio transmission device 8a or 8b, the elevator control system determines whether or not the car 5 exists in the landing area (step S201). The current position of the car 5 is determined by the car-side control device 6 according to the state of the landing switch 13 provided in the car 5. For example, when the car 5 is in the landing area, the landing switch 13 transmits the landing signal of the car 5 to the car-side control device 6.

  If the car 5 exists in the landing area and is landing (YES in step S201), the car-side control device 6 opens the car 5 and lowers the passenger (step S202). When the car 5 does not exist in the landing area and is not landing (NO in step S201), the control panel side control device 3 performs a safety circuit confirmation process (steps S100 to S101 in FIG. 3). Run. Thereafter, the car-side controller 6 executes a door-opening travel prevention process (step S102 ′ in FIG. 3).

  Here, the safety circuit confirmation processing (steps S100 to S101 in FIG. 3) of the present embodiment is the same as steps S100 to S101 in FIG.

  The door-opening travel prevention process (step S102 ′ in FIG. 3) of the present embodiment is a determination as to whether or not the car sensor and the switch 12 are abnormal by the car-side control device 6. When the wireless transmission device 8 is normal (FIG. 2), the control panel side control device 3 executes the state determination of the car sensor and the switch 12 via the wireless transmission device 8, but an abnormality is detected in the wireless transmission device 8. In such a case, the state cannot be determined via the wireless transmission device 8. For this reason, the car-side control device 6 executes the state determination of the car sensor and the switch 12 via the transmission path (wired C).

  Hereinafter, the process of determining the state of the car sensor and the switch 12 by the control panel side control device 3 will be referred to as step S102, and the process of determining the state of the car sensor and the switch 12 by the car side control device 6 will be referred to as step S102 ′.

  The car-side control device 6 generates a car travel permission signal from the state of the car sensor and the switch 12 and transmits it to the control panel side control device 3 via the transmission cable 7.

  When there is an abnormality in the state of the car sensor and the switch 12 (NO in step S102 ′), the car-side control device 6 transmits a signal for turning off the car travel permission signal to the control panel side control device 3 (step). S203).

  The signal obtained by turning off the car traveling permission signal is a signal indicating that traveling is not permitted. Further, step S203 may be a process of not transmitting the car travel permission signal.

  When the car travel permission signal is turned OFF (step S203), when the state of the machine room sensor and the switch 10 is abnormal (NO at step S100), when the state of the hoistway sensor and the switch 11 is abnormal (step S101) NO), the elevator control system again determines whether these sensors and switches are normal (steps S100 to S102 ′).

  When there is no abnormality in the state of the car sensor and the switch 12 (YES in step S102 ′), the car-side control device 6 sends a signal indicating that the car travel permission signal is turned ON via the transmission cable 7 to the control panel side. It transmits to the control apparatus 3 (step S204).

  When the control panel side control device 3 receives the ON signal of the car travel permission signal via the transmission cable 7, the control panel side control device 3 determines that the car 5 can travel and switches to the low speed travel (step S205) to change the car 5 To run. The low-speed traveling is an operating state of traveling that is decelerated from the normal traveling. However, switching to low-speed traveling (step S205) is not always necessary, and the processing may be omitted.

  The car-side control device 6 determines whether the car 5 has entered the landing area (step S206). If the vehicle is not within the landing area (NO in step S206), the car-side control device 6 continues to output the car travel permission signal ON (step S204). When the vehicle enters the landing area (YES in step S206), a signal with the car traveling permission signal turned off is transmitted to the control panel side control device 3 via the transmission cable 7 (step S207). Or step S207 is good also as processing which does not transmit a car run permission signal.

  When the control panel side control device 3 receives the signal for turning off the car travel permission signal, the control panel side control device 3 stops the elevator and causes the car 5 to land (step S208).

  After the car 5 has landed, the car-side control device 6 opens the car 5 and lowers the passenger (step S209).

  As a result, the elevator control system of the present embodiment prevents the passenger from being trapped by continuing the signals between the car 5 and the control panel 2 by the transmission cable 7 even when the wireless transmission device 8 fails. be able to.

  In the present embodiment, the door-opening travel prevention process (step S102 ′ in FIG. 4) is performed by the car-side control device 6 through the transmission path (wired C) to determine whether the car sensor and the switch 12 are abnormal. I do.

  That is, regarding the state of the machine room sensor and the switch 10 and the state of the hoistway sensor and the switch 11, whether or not there is an abnormality is determined by the control panel side control device 3 (steps S100 to S101). The presence / absence determination is made by the car-side control device 6 (step S102 ′).

  Further, as in FIG. 3, the car-side control device 6 generates a car travel permission signal from the state of the car sensor and the switch 12, and transmits it to the control panel side control device 3 via the transmission cable 7.

  When there is an abnormality in the state of the car sensor and the switch 12 (NO in step S102 ′), the car-side control device 6 transmits a signal for turning off the car travel permission signal to the control panel side control device 3 (step). S203).

  When the car travel permission signal is turned OFF (step S203), when the state of the machine room sensor and the switch 10 is abnormal (NO at step S100), when the state of the hoistway sensor and the switch 11 is abnormal (step S101) NO), the elevator control system again determines whether these sensors and switches are normal (steps S100 to S102 ').

  When there is no abnormality in the state of the car sensor and the switch 12 (YES in step S102 ′), the car-side control device 6 sends a signal indicating that the car travel permission signal is turned ON via the transmission cable 7 to the control panel side. It transmits to the control apparatus 3 (step S204).

  The control panel side control device 3 determines that the elevator can travel and performs normal traveling (step S103). Similarly to the first embodiment, the normal traveling is, for example, raising / lowering control of the car 5 by the control panel side control device 3 and door opening control of the car 5 by the car side control device 6.

The elevator control system of this embodiment has a function of generating a car travel permission signal of the car-side control device 6 when the radio transmission device 8 (the control panel-side radio transmission device 8a or the car-side radio transmission device 8b) is normal. By using the control panel side control device 3, it is not necessary to check the state of the car sensor and the switch 12 via the wireless transmission device 8 (from the control panel side wireless transmission device 8a to the car side wireless transmission device 8b). . Accordingly, it is not necessary to transmit the state of the car sensor and the switch 12 to the control panel 2 via the wireless transmission device 8 (from the control panel side wireless transmission device 8a to the car side wireless transmission device 8b). Can be reduced.
As a result, the elevator control system of the present embodiment prevents the passenger from being trapped by continuing the signals between the car 5 and the control panel 2 by the transmission cable 7 even when the wireless transmission device 8 fails. be able to.

  Furthermore, even when the wireless transmission device 8 is normal, it is possible to reduce the amount of data by wireless transmission by transmitting a car travel permission signal.
