At this time, the call button unit 303 generates a key signal according to the call and inputs it to the call control unit 302. The call controller 302 outputs the call key signal to the relay unit 200 through the transmitter 301, and simultaneously causes the display lamp 305a to be turned on by the second floor through the display unit 305.

The call key signal transmitted through the transmitter 301 is received by the receiver 201 of the repeater 203, and the key signal received by the receiver 201 is input to the repeater controller 202.

The repeater controller 202 wirelessly transmits the call key signal to the lift main control apparatus 100 through the transmitter 203 and simultaneously guides the current lift driving state through the voice output unit 204 and the speaker 204a. It outputs by voice.

The signal transmitted through the transmitter 203 of the repeater 200 is received by the receiver 101 of the lift main controller 100, and the received signal is input to the main controller 102.

The main controller 102 reads the input call key signal, recognizes that the lift is called by the floor call controller 300 on the first floor, and outputs the lift driver 104 to drive the lift 20. To move to the first floor.

Therefore, the user will board the lift 20 arrived on the first floor. After boarding, the user selects a floor to go through the floor selection button part 107 of the lift main control device 100 and completely closes the lift door 21 at the entrance, that is, the floor selection button part 107 is closed. When the floor key signal selected through the main control unit 102 is input, and the closing of the entrance door is detected through the door opening detection sensor 106a and the door opening detection unit 106, the main control unit 102 lifts the lift. The lift 20 is moved upward to the second floor by driving the driving unit 104.

The guide voice is continuously output repeatedly, and the emergency stop display lamp 110a is turned on through the display unit 110.

At this time, when the user manipulates the emergency stop buttons 111a to 111c once more (turns to the right once more: a rotary switch) to release the emergency stop state, the main control unit 102 via the emergency detection unit 111 is used. Blocks the voice guidance for emergency stop receiving the input, and turns off the emergency stop display lamp (110a).

At this time, the main controller 102 deletes the number of floors of the destination initially designated by the user from the storage 103. Therefore, the user has to select the floor to go through the floor selection button unit 107 again, and the lift 20 is activated again.

(5) Lift drive state abnormality detection operation

The value input through the driving sensor 105 is continuously detected during the operation of the lift 20. Here, when an abnormality of the sensor detecting the operation of the lift driver 104 is detected, the main controller 102 stops the output of the lift driver 104 to stop driving of the lift 20, and the voice output unit 108. And through the speaker 108a to continuously output the guide voice for the sensor abnormality, and through the display unit 110 to turn on the sensor abnormality display lamp (110a).

At this time, when the administrator takes the action on the sensor abnormality and normalizes it, the main control unit 102 is inputted through the driving detection unit 105 to block the guide voice for the sensor abnormality, and turns off the sensor abnormality display lamp 110a. give.

The main controller 102 deletes the number of floors of the destination initially designated by the user from the storage 103. Therefore, the user has to select the floor to go through the floor selection button unit 107 again, and the lift 20 is activated again.

(6) Reference point and upper limit detection operation

During the operation of the lift 20, when the lift 20 comes to the bottom (origin) surface, it is detected by the reference point sensor 112a. When the lift is detected on the floor by the reference point sensor 112a and the reference point detector 112, the main controller 102 may generate an error (for example, whenever the lift stops while driving). 2cm error occurs).

In addition, during the operation of the lift 20, when the lift 20 comes to the upper limit it is detected by the upper limit detection sensor 112b. When it is detected that the lift reaches the upper limit through the upper limit detection sensor 112b and the reference point detecting unit 112, the main controller 102 changes the driving environment so that the lift is lowered back to the bottom surface. In other words, the reverse rotation of the lift motor.

(7) repeater announcement

According to the present invention, the repeater 200 may wirelessly relay the signal of the floor call controller 300 to the lift main controller 100, as well as various kinds of guides through the voice output unit 204 and the speaker 204a.
