Description

STZHSC U11RAV1ENYA by SHCH1K LST:

The utility model relates to hoisting and transporting mechanisms, in particular to control devices for passenger and freight elevators in residential and industrial buildings.

Known elevator control station (Relay station ShK 5903, TU 16 536,020-78), containing a sensor unit, call and command posts connected via a logic block to a relay control unit for actuator elements of the elevator. Call and command posts are made in the form of panels with push-button switches installed on floors and elevator cabs respectively. The logic block is made entirely on relay elements and contains a block for selecting the direction of movement of the elevator and an elevator door control unit connected at the input by multi-core cables with push-button switches of call and order posts, load sensors, door sensors, floor sensors and sensors of mine safety apparatuses, and at the exit - through a logic device with the input of the relay control unit for the actuator elements of the elevator. The relay control unit contains a series-connected block of intermediate relays with a unit forcing the braking of the elevator and a block of magnetic starters.

A disadvantage of the known elevator control station is the difficulty of its use in multi-storey buildings of more than 10 floors due to weight restrictions of multi-core communication cables of the station elements with each other and with the corresponding floor and mine safety sensors.

The basis of this utility model is the task of creating an elevator control station, the design of which allows to reduce the required number of communication wires between elements

stations, their total weight and, as a result, expand the functionality of the stashi, namely, to ensure the possibility of using the station in buildings with a number of storeys over 10 floors.

The solution to this problem is achieved by the fact that in the elevator control station containing the sensor unit, call and command control panels connected through the logic unit to the relay control unit of the actuator elements of the elevator, according to the utility model, the logical unit is designed as a microcontroller, and call and command control panels made in the form of matrix control units. In this case, the microcontroller is made in the form of a separate printed circuit board on large integrated circuits of the type КР I8I6 Б1Ю, and the matrix control units are in the form of a key switch with a matrix arrangement of contact buses. Logic and relay blocks are placed in a common housing made in the form of a cabinet.

The introduction of these differences allowed us to reduce the required number of wires in the elevator shaft, in the control cabinet, the number of input / output elements on the microcontroller board and the number of terminal blocks in the control cabinet. At the same time, the overall weight and size characteristics of the elevator were reduced and the possibility of using the elevator control station to 25 floors in residential buildings and to 17 floors in administrative and medical buildings was ensured.

The drawing shows a functional diagram of the elevator control station.

The station contains a block I of sensors, an order 2 and call 3 control panels connected through a logical unit 4 with a block 5 for controlling the actuator elements of the elevator. Sensor block I contains elevator load sensors, door sensors, floor sensors.

mine safety sensors. The order 2 and call 3 control panels are made in the form of a matrix control apparatus, for example, in the form of a key switch with a matrix arrangement of contact buses. The outputs of the sensors of block I and panels 2 and 3 are connected through an optocoupler isolation to logic block 4. Consumer 4 is designed as a microcontroller (microprocessor board 1Sh I7-HP) on a separate printing staff on large integrated circuits (LSI) type КР 1816 BEZ, microprocessor architecture boards made with the possibility of coaxing to it the outputs of elements 1,2,3, combined into an external signal matrix of size 8x13. Potential outputs of block 4 are connected to the input of relay block 5, Block 5 contains series-connected block 6 of intermediate relay and block 7 of magnetic starters. The outputs 8,9,10 of block 7 are the control outputs of the winch engine, electromagnetic brake and door drive motor, respectively.

During normal operation of the station, in block 4, the signals from the sensors of block I and the panels of orders 2 and call 3 are analyzed. When a call signal 3 is received, the last in block 4 is compared with the signal parameters of the floor sensors of block I, if the call is fixed on the elevator floor, microcontroller 4 generates a signal for opening doors, which is fed to the corresponding relay of unit 6. The relay activates and switches on the magnetic starter of unit 7. At the same time, voltage appears at the output of station 10 to turn on the drive motor verey for opening. After the doors of the elevator car and the shaft are completely opened, the microcontroller 4 receives a signal from the door open state from block I. As a result of this, the microcontroller 4 generates a signal to turn off the power from the door drive. The corresponding relay of block 6 and the magnetic starter of block 7 are de-energized. At the same time, exit 10

station on the door engine issued a brake signal. If after opening the doors the passenger did not enter the cabin, the signal from the load sensor of block I did not arrive at block 4, the latter generates a door closure signal in 3-5 seconds and the doors close. If a passenger entered the cabin after opening the doors, the signal from the load sensor of block I is sent to microcontroller 4 and the latter generates a permission signal for fixing orders from the elevator car.

At the same time, the received order signal from block 2 is fixed and stored in the RAM of the microcontroller 4, after that, the corresponding indicating signals are issued to the order panel 2 in the elevator car, in block 4 the direction of the elevator car is selected and a door closure signal is generated, which through block 6 intermediate relays and block 7 magnetic starters issued to the door engine. If there is an obstacle in the process of closing the doors, the door reverse sensor of unit I is triggered, which leads to the shutdown of 4.6.7 door closing engines using the blocks. After a time delay, the door closing motors are switched back on. After the process of closing the doors of the elevator and the shaft is completed, the closing sensor of the doors of block I is triggered and gives a signal to the microcontroller 6. The latter, in accordance with the previously selected direction of movement of the elevator, gives a signal through block 6 of the intermediate relays to the magnetic starter of block 7 to turn on the winch motor. When the elevator moves along the shaft, the deceleration sensor of block I is hit by the corresponding shunts. At the same time, a braking signal is generated in block 4, with the help of which the corresponding relay of block 6 and the magnetic starter of block 7 are turned on, ensuring the elevator drive switches to low speed. When the sensor stops the exact stop of block I on a shunt located at the floor level, a signal is generated in block 4 to stop the drive

elevator winch. After stopping and opening the cabin doors in block 4, the executed order and call are removed from the queue. In this case, the corresponding LEDs on the order 2 and call 3 control panels go out.

Next, the elevator control process is repeated for subsequent calls and orders.

The proposed elevator control station is industrially applicable. Experimental stations have been developed at Eltor CJSC. Their successful test was carried out in residential buildings with floors of up to 25 floors and in industrial buildings up to 17 floors.
