The elevator is an essential vertical transportation means in the building. In the conventional elevator control system shown in FIG. 1, if there is a call of a passenger at the platform, the passenger is safely moved to the destination floor by driving the passenger in the elevator car, So as to control the elevator.

When the elevator is largely divided into spaces, a machine room 10 in which various mechanical equipment for elevator operation is installed, a landing platform 70 in which a passenger lifts the elevator, a car interior 20 ), A car top (30) as a car upper space, and a pit.

<Machine room>

For example, in the elevator machine room 10, the operation control panel 11, the motor control portion 12, the emergency call master key 15 and the remote control terminal 18 are provided as separate devices each having a separate control board .

The operation control panel 11 receives the calling call of the platform and takes charge of the overall operation control for the passenger to move to the desired destination floor. The motor control section receives the motor drive command from the operation control panel 11 and drives the motor 13 in a forward or reverse rotation (a series of actions such as acceleration, constant speed, deceleration and stop) to move the passenger to the target floor .

The emergency call master key 15 carries out overall call management and connection such as connection control and mutual call connection with an internal or external manager in case of an emergency such as confined passenger in a car.

The remote management terminal 18 monitors the operation status of the elevator and receives a control command from the remote control center to notify the remote control center of the occurrence of a problem, thereby enabling the elevator remote control operation. The elevator operation history calculation, storage and fault history storage .

<Car>

In the elevator car 20, a car communication control unit 21, a car object floor calling and registering unit 24, an automatic voice guidance broadcast unit 23, and a car emergency call magnet 25 have separate control boards And is provided as a separate device.

When the car communication control unit 21 receives the running data from the elevator driving control panel 11 and transmits the data to the automatic voice guidance broadcasting apparatus 23, the automatic voice guidance broadcasting apparatus 23 outputs the corresponding recorded voice by sound It informs the passengers about the current driving status information.

The car communication control unit receives the call input and the operation mode from the car object floor call and registration unit from the car object floor call and registration unit, and transmits it to the operation control board of the machine room. Then, the operation control board executes the logic related to the operation control When a result value is returned to the car communication control unit (21), the destination floor is registered in the car object floor calling and registration unit (24).

The car emergency call dispenser 25 is provided to allow an emergency call to the internal (19) or external custodian (50) in preparation for an emergency such as in-car passenger confinement.

A car door control unit 32, a car emergency communication unit 33, and an emergency power supply unit 31 are provided as separate units each having a separate PCB on the elevator car top 30.

However, the conventional elevator control system having the above-described configuration has the following problems.

(1) Problems of machine room devices

The control boards provided in the respective devices 11, 12, 15 and 18 provided in the conventional machine room 10 are individually provided with a central processing unit (CPU), a memory (ROM, RAM (RAM)), clocks, peripheral devices, and power supplies.

The control boards of the respective devices 11, 12, 15, and 18 in the conventional machine room 10 are connected to each other by a cable to cause a contact failure and a cost increase factor.

Serial or parallel communication between the control boards of the respective devices 11, 12, 15 and 18 in the conventional machine room 10 and data transmission and reception by input and output are performed, so that the central processing unit (CPU) Since the input / output must be read, it affects the load factor of the normal processing logic part of the central processing unit (CPU), which can act as an instability factor of the system and delay the data processing due to the communication cycle.

It may or may not accurately detect whether the passenger is trapped or not depending on which control board is installed in each of the devices 11, 12, 15, and 18 in the conventional machine room 10.

(2) Problems of in-car devices

The control boards of the respective devices 21, 23, 24, and 25 provided in the car 20 in the related art have a central processing unit (CPU), a ROM, a RAM, a clock , It is necessary to provide peripheral devices, thereby causing a cost increase.

The control boards of the respective devices 21, 23, 24, and 25 of the car 20 in the related art are connected with each other by a cable, which causes a contact failure and causes a cost increase due to the unit price of the cable.

In the conventional elevator control system, it is possible to recognize only whether the emergency call has been made in the car emergency call entity 25 by only the emergency call carrier value 15 in the machine room, (25) If there is a fault, emergency call can not be made because it is impossible to determine whether or not the emergency call is made.

In the conventional elevator control system, since the automatic voice guidance broadcasting device 23 and the car emergency call device 25 must separately include the speaker for guidance and the speaker for car emergency communication, the cost increases. There has been a problem in that flexibility in determining the installation number, etc. is deteriorated.

In the conventional elevator control system, the automatic voice announcement broadcasting apparatus 23 detects a power failure and performs power failure guidance broadcasting when a power failure occurs due to some influence. At this time, There is a problem that the use time of the capacitor of the emergency power supply is shortened because the emergency power supply is received.

In the conventional elevator control system, if the emergency call calling button of the car emergency call person 25 is pressed, it is necessary to visually and audibly confirm whether or not the emergency call is made for the disabled person and whether the emergency call is connected to the internal or external caretaker. Since the voice / hearing / LED (time) etc. must be operated using the central processing unit (CPU) in the car emergency call, the size of the control board becomes large, which causes a cost increase. Space utilization is also very low.

In the conventional elevator control system, even when the automatic voice guidance broadcasting apparatus 23 receives the driving-related information data from the driving control panel, the in-car emergency calling party receives only the emergency call from the passenger (25) There has been a problem that it is impossible to respond to a state of elevator operation (e.g., passenger confinement, etc.) when a call is made.

(3) Problems of Car Top Devices

The control boards of the respective devices 31, 32, and 33 provided in the conventional car top 20 have a central processing unit (CPU), a ROM, a RAM, a clock, a peripheral It is necessary to provide the elements, which leads to a rise in cost.

In the conventional elevator control system, the door control unit 32 of the car upper 30 performs a control dependent on the operation control panel 11 of the inside of the machine room 10, thereby causing a delay in controlling the elevator car door And the passengers are exposed to the risk of safety accidents.

That is, in the conventional elevator control system, as shown in FIG. 2, the passenger boarding / unloading information recognized by the sensor such as the safety shoe of the car is transmitted to the driving control board by the card control unit, Depending on the command, the car door is opened or reopened. However, when the passenger boarding or getting off when the car door is closed, the sensor senses (safety shoe or photo sensor, etc.) and inputs it to the door control unit 32 and the door control unit 32 to the operation control board 11 in the machine room When the data is transmitted and the operation control panel combines the data with the current elevator status information and returns the result to the card control unit 32, the card control unit 32 controls the card door to reopen or close the door There is a problem that a passenger who is getting on and off due to a time delay from the sensing operation of the sensor to the car door control causes an accident that the door is hit by a collision

In the conventional elevator control system, it is determined whether or not the battery 34 of the emergency power source device 31 in the car top 30 is charged or discharged to exceed a predetermined reference value, and charging / discharging is terminated There has been a problem that it is impossible to confirm the predicted time of how much the battery can be used in the load operation such as the emergency light or the battery abnormality in the future.

In the conventional elevator control system, when the passenger is trapped in the car due to power failure, the door control unit (32) of the car upper (30) has to manually open the door manually by adjusting the car to the door opening position first.

Since the conventional elevator control system applies a different communication protocol between each device on the car, the central processing unit (CPU) needs to process the data communication from each of these devices as a communication interrupt, The central processing unit (CPU) and the peripheral devices all have to use the parts having high processing speed, which is a factor of cost increase.

In the conventional elevator control system, since each of the PCBs provided in the machine room, the car, and the car are separated into separate units, devices in the respective spaces must transmit data by communication, resulting in a communication delay, The cost of various parts is increased.
