Abstract

A system operates to save passengers during a state of emergency when the elevator is out of order. The controlling circuit comprises a detecting element (100), which detects the moving direction before the elevator stops at any other zones except a door open zone; a commanding element (200), which orders the save command into the rescue up or the rescue down of the elevator; a time element (300), which controls the elevator when it does not moved after a designated time; and an alarm element (400), which indicates inoperability of the save.

The present invention not only enables the rescue operation reliably even when an abnormality occurs in the elevator up / down operation dedicated equipment, but also checks the emergency stop state in the uppermost floor and the lowermost floor to check the emergency state in the lowermost floor of the top floor. In the case of falling command, in the case of the lowest floor, the rising command is given, and if the car is not driven after the rescue operation command is issued from the other floor except the highest and lower floors, the operation command in the direction opposite to the initial rescue operation command direction is given. The present invention relates to a control circuit that can be performed again to perform a complete passenger rescue operation function.

In general, when driving stops in the middle of the floor, the main cause is failure of the equipment used or contact failure.In case of stopping in the middle of rising or falling, the system relays And the failure of related parts is the main cause.

Therefore, in the conventional rescue operation method, the rescue operation is uncertain because the rescue operation is performed in a predetermined direction (generally, the downward direction), so the manager is called by the interphone to release the brake of the machine room and the car door opening area by manpower. Because it has to move into the door open zone, it not only has a mental shock to the passengers in the car, but there is also a possibility of causing a great casualty when the elevator is overrun on the top and bottom floors. .

The present invention has been invented to completely solve the problems caused under the rescue operation situation in view of the conventional problems, which will be described in detail with reference to the accompanying drawings.

Referring to the effects of the present invention configured as described above are as follows.

Prior to explaining the circuit operation of the present invention, Figure 3 is a generalized driving circuit of the elevator, SW ₂ is the up operation button, SW ₂ is the down operation button, R _F is the up operation relay, R _G is down operation Relay S is an operation command relay. When the driving direction is determined by pressing button SW ₂ or SW ₃ , the corresponding relays R _F and R _G are driven to reach the target floor. 10) and the segment 20 are in contact with each other to drive the relay of the corresponding layer.

R ₁ is the lowest floor operation detection relay.

R _N is the top floor operation detection relay

R ₂ -R _M is an operation detection relay for each floor. When the elevator reaches a location on the floor, the contactor 10 and the segment 20 are in contact with each other, and the operation detection relay on the floor is driven. It is known to perform the function of stopping the elevator by turning off the relay S when the elevator reaches the target floor as a switching.

FIG. 1 is a flow chart of the present invention, when the elevator stops outside the door opening area during an ascending operation, it checks whether it is the lowest floor, and if it is not the lowest floor, delivers a rescue operation command in the downward direction, and the car cannot be driven down. In the case of, rise command is issued again.

If the car is located on the lowest floor, the rescue operation command is first issued in the upward driving direction to prevent accidents caused by the speeding of the elevator in advance, and even though the above operation command has been issued due to a relay or component failure, If the vehicle cannot be driven, the rescue operation command, which is the opposite direction from the driving direction, is issued again. In addition, when automatic rescue operation is impossible regardless of the position where the elevator is stopped, the indicator lights and the buzzer is rolled to indicate the rescue operation impossible status.

This will be described in detail with reference to FIG. 2 showing a sequence circuit of the present invention.

For example, assuming that the elevator has made an emergency stop other than the door opening area during the ascending operation on the top floor and the bottom floor, the door opening area detection non-contact switch DZ in the driving direction detection unit 100 is ON because the elevator is not located in the door opening area. In this state, the power source B ⁺ is applied to the door open area detection relay R _A through the switch DZ to drive the relay R _A.

At this time, since the elevator is in the ascending operation, the ascending operation relay R _F shown in FIG. 3 is driven so that the contact point Fa ₁ of the a is turned on, so that the power supply B ⁺ is the contact point A a _1- (Fa _1). The rising operation detection relay R _E other than the door opening area is driven through the)-(Db ₁ ) (the contact b of the rescue operation rising direction relay R _D is not driven at this time).

In this case, since the operation command relay S shown in FIG. 3 is driven and its contact b Sb ₁ is in an OFF state, the hold circuit configuration is (Aa ₁ ) → (Sb ₁ ) → (Cb _1). (B) → (Db ₁ ) → (RB) and (Aa ₁ ) → (Sb ₁ ) → (Bb ₁ ) → (Eb ₁ ) → (Rc). In addition, since the elevator is in the ascending operation, the descending driving relay RG shown in FIG. 3 is not driven, and thus the contacting point Ga ₁ of the lowering state is OFF, so that the descending driving detection relay Rc other than the door opening area is not driven. . When the elevator stops under this condition, the relay R _B continues through the path of power (B ⁺ ) → contact (Aa ₁ ) → (Sb ₁ ) → (Cb ₁ ) → (Db ₁ ) → (RB). Driven.

In addition, since the operation command relay S is not driven due to the elevator stop, its contact b (Sb ₁ ) is turned on so that the falling operation detection relay other than the door open area is opened by the path of B ⁺ → Sb ₁ → Bb ₁ → Eb ₁ → Rc. (Rc) is driven. Here, the driving states of the up or down relays R _B and R _C are delayed by the resistor r ₁ , the capacitor C ₁ , the resistor r ₂ , and the capacitor C ₂ . As a circuit, the relay R _B is always driven after an emergency stop during ascending operation, and the relay Rc is delayed to be driven after an emergency stop during a descending operation. Therefore, the driving direction immediately before the elevator stops abnormally in the middle of the floor. Will be detected.

In this way, since the relay R _A continues to be driven, the downward direction rescue operation command relay R _{E in the} rescue direction command unit 200 is supplied with power (B ⁺ ) -Aa ₂ -TYb ₁ (when the relay TY is It is ON because it is not driven .- (Ba ₁ ) -TXb ₂ (It is ON because relay (TX) is not driven.)-Sb ₃ -1b ₁ (Low-level relay (R ₁ ) is not driven. state because the oN state Im) prior to malfunction due to the (R _E), the path is a relay (R _E) is driven in the so that issued the rescue operation command ever run the elevator to the falling direction of the rising opening relay or associated components malfunction, etc. Will be prevented.

At this time, if the elevator fails to move down after the set period elapses after the mile down direction rescue operation command relay (R _E ) is driven, the power source (B ⁺ ) → Ea ₃ → Nb ₂ (the top floor detection relay (R _N ) is driven. Since it is not in the state, it is ON.) → Sb ₄ → Delay timer (TM) counts through the path of timer (TM), and the auxiliary relay (TX) of timer (TM) is powered (B ⁺ ) → timer (TM). The power is applied by a path of a contact (TN ₁ ) → (Aa ₃ ) → (TX) of the auxiliary relay TX, and the auxiliary relay TX is held by the magnetic contact TXa ₁ .

As the relay TX is driven, the ascending direction rescue operation command relay R _D is driven by the path of power (B ⁺ ) → TXa ₂ → Ea ₂ → Ba ₂ → R _D to operate the elevator in the upward direction. In this case, the relay R _E is not driven because the contacts Db ₂ and Ba ₁ are turned off. In this case, if the elevator does not start even after the ascending operation command relay R _D is driven and the ascent command is issued, the contact a of the power supply (B ⁺ ) -relay TX (TXa ₃ ) -timer The timer TN is operated after the set time has elapsed by the path of (TN), and the contact a connected to the relays R _D and R _E because the relay TY is driven because the contact aN TN ₁ is turned on. As (TYb ₁ ) is turned OFF, the rescue operation command is canceled because both the rising and falling rescue operation command relays (R _D ) and (R _E ) are not driven.

In this state, each of the a contacts TYa ₂ and TYa of the relay TY in the display alarm unit 400 is turned on so that the power supply B ⁺ is applied to the indicator light L and the buzzer BZ. The rescue operation will be displayed and the alarm signal will be issued. Therefore, the manager will be informed that the passenger must be rescued by artificial manipulation.

On the other hand, if it is assumed that the elevator has made an emergency stop outside the door opening area during the ascending operation in the lowest floor area, the lift operation detection relay (R _B ) is driven because the elevator stopped during the ascending operation. (R ₁₎ is driven, so that his b contact (1b ₁₃₎ OFF the falling direction rescue operation command relay (R _E) connected thereto is able not driven.

Therefore, ascending direction rescue operation command relay (R _D ) is inputted from the path of power (B ⁺ ) → Aa ₂ → TYb ₁ → Ba ₁ → TXb ₂ → Sb ₃ → 1a ₁ → Nb ₁ → R _D The command relay R _D is driven to control the rescue operation direction of the elevator in the upward direction.

In this case, if the driving state becomes impossible until a predetermined time elapses even after the rising direction command, the relay TX is driven as described above to secondly receive the direction reversal command.

If it is impossible to continue driving after the first and second rescue operation commands have been issued, the rescue operation command is canceled as described above, and the rescue operation impossible status is indicated as an indicator (L) and a buzzer (BZ) and an alarm signal is issued. Even if the elevator is emergency stop in the uppermost floor, the rescue operation command is canceled by the circuit operation of the same principle, and the indicator L and the buzzer BZ indicate the impossible operation and the alarm signal is issued.

According to the present invention operating as described above, the rescue operation direction of the elevator is lowered in the lowermost section, the lower direction in the lower direction, and the lower direction is lowered in the lower direction. When the passenger carries out safe rescue operation and the elevator becomes inoperable after the rescue operation command, the command is issued in the direction opposite to the direction of the first rescue operation command, and even after the first and second rescue operation commands mentioned above. If the elevator becomes inoperable due to failure or other conditions, it will be displayed as an indicator light and a buzzer and an alarm will sound to signal the manager to rescue the passengers by artificial manipulation. To provide the effect.
