The present invention relates to a test drive device of the elevator for automatically checking or confirming the overall operating state of the elevator after installation in the building.

Conventionally, in order to check or confirm the general operation state of an elevator, a corresponding operation relay of a hole and a cage is manually turned on by a manual operation in a machine room, or an inspector may call a hole in a hall or board a cage. It was to register the call and perform the trial operation of the elevator. However, if one person in the machine room is going to perform a test operation, it is necessary to operate the elevator every time due to the call before turning on the corresponding operation relay of the hall and cage by manual operation. After confirming the position, the corresponding operation relays of the holes and cages must be forcibly turned on, which causes the test operation to be very cumbersome and to bring about human and time wastage.

The object of the present invention is to allow automatic test operation as much as the number of operation inputted to the 4-bit comparator in consideration of all the conventional problems, and to make the test operation very convenient and to eliminate human and trial waste. It is.

When described in detail by the accompanying drawings of the present invention as follows.

1 shows a circuit configuration diagram of the start frequency comparison section according to the present invention, and the master reset input terminals of the 4-bit ripple counters 2 and 3 are connected to the output terminal Q of the monostable multi-vibrator 1. (MR ₁ ) and (MR ₂ ), respectively, and the contact a 11a of the up-driving contact 11 (shown in FIG. 4) of the elevator and the contact a 12a of the down-driving contact 12 Connected to the input terminal CP of the 4-bit ripple counter 2, and the output terminals Q ₀ , Q ₁ , Q ₂ , and Q ₃ of the lower 4-bit comparator 4 Input terminals (A ₀ ), (A ₁ ), (A ₂ ) and (A ₃ ) are connected respectively, and the lower 4 bit ripple counter (3) is connected to the output terminal (Q ₃ ) of the 4-bit ripple counter (2). The number of operation is extended to 8 bits by connecting the input terminal (CP) of the upper 4 bits, and the upper 4 bits in the output terminals (Q ₄ ), (Q ₅ ), (Q ₆ ), and (Q ₇ ) of the 4-bit ripple counter (3). Input terminals A ₄ , A ₅ , A ₆ , and A ₇ of the comparator 5 are connected, and The output terminals (Q _A > B) and (Q _A <B) (Q _A = B) of the lower 4-bit comparator 4 have input terminals (I _A > B) (I _A <B) of the 4-bit comparator 5. (I _A = B) are connected to each other, and the start frequency confirmation relay R is connected to the output terminal Q _A = B through the transistor TR ₁ .

Reference numerals 511T, 512T... … 51nT is one layer, two layers. … n-level cage call registration relay I is the test operation confirmation relay for the elevator 100 is the operation command relay Rb is the contact point b of the start frequency check relay (R), and 911a and 911b are contacts a and b of the reference floor positioning relay of the elevator. 91nb is the contact point b of the elevator's top-level positioning relay, Ia is the contact point a of the test operation check relay (I), Ca and Cb is the a. Chongqing of contacts b, Ta, and Tb are cage call registration relays for test operation. Generic values of contacts a and b of contact relays R ₁ and R ₂ are resistors C ₁ and C ₂ are capacitors and SW is test drive switch.

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

In FIG. 1, when the initial power is turned on, the resistor R ₂ and the capacitor C ₂ at the rising edge of the moment when a high state signal is applied to the input terminal B of the monostable multivibrator 1. The pulse number signal having the time constant width by appears on the output terminal Q as shown in FIG.

In this way, the pulse signal represented by the output terminal Q is applied to the master reset input terminal MR ₁ (MR ₂ ) of the 4-bit ripple counter (2) and (3), so that its output terminals Q ₀ and (Q ₁ ). ), (Q ₂ ), (Q ₃ ) and (Q ₄ ), (Q ₅ ), (Q ₆ ), and (Q ₇ ) all result in a low signal.

That is, the monostable multivibrator 1 outputs a pulse signal to the output terminal Q while the signal applied to the input terminal B is a rising edge to reset the initial value of the 4-bit ripple counter (2) (3). After setting, the signal applied to the master reset input terminals MR ₁ and MR ₂ of the 4-bit ripple counters (2) and (3) is kept low.

In this state, when the elevator receives the call registration of the hole or the cage and moves up or down, each time the up or down operation is performed, the contact a (11a) (12a) of the up or down driving contact (11) (12) Is turned on to apply the click signal of the high state to the clock input terminal CP of the 4-bit ripple counter 2, so that the 4-bit ripple counter 2 counts the number of driving operations of the elevator. Output signals Q _{0 to} Q ₃ appear as shown in the truth table in FIG.

Thus, by applying the signal appearing at the output terminals Q _{0 to} Q ₃ of the 4-bit ripple counter 2 to the respective input terminals A _{0 to} A _{3 of} the lower 4-bit comparator 4, the lower 4-bit comparator ( 4) is input to other input terminals B ₀ , B ₁ , B ₂ , and B ₃ according to the signal counted by the 4-bit ripple counter 4 and the setting operation of the switch group SWg. The upper 4 bit comparator 5 compares the output terminals Q ₄ , Q ₅ , Q ₆ of the 4-bit ripple counter 3 with each other. High order 4-bit comparator (5) by setting operation of counter group and switch group (SWg) applied from (Q ₇ ) to input terminals (A ₄ ), (A ₅ ), (A ₆ ), (A ₇ ) It is compared with the signal (higher 4 bits of 8 bits) applied to the other input terminals (B ₄ ), (B ₅ ), (B ₆ ), and (B ₇ ).

At this time, the input terminal (I _A = B) of the lower 4 bit comparator 4 is set to the high state in order to perform extended comparison to 8 bits, and the output terminal (Q _A > B) and the input of the upper 4 bit comparator 5 are high. Terminal (I _A > B) Output terminal (Q _A &lt; B) of lower 4 bit comparator 4 and input terminal (I _A &lt; B) of lower 4 bit comparator (5) Output terminal of lower 4 bit comparator (4) By connecting (Q _A = B) and the input terminal (I _A = B) of the upper 4-bit comparator 5, respectively, an output value as shown in the truth table of FIG. 8 is obtained.

Next, a description will be given of the test operation of the elevator.

When the test drive switch SW shown in FIG. 3 is turned on for the test drive of the elevator, the test drive confirmation relay I is driven to turn on the contact aa shown in FIG.

At this time, the 4-bit ripple counter (2), (3) is a state in which a low signal is applied to the master reset input terminals (MR ₁ ), (MR ₂ ) after the initial value is reset as described above. Therefore, the clock signal according to the elevator rising or falling to the input terminal CP of the 4-bit ripple counter 2 is connected to the a contact 11a of the rising driving contact 11 or the a contact 12a of the falling driving contact 12. When applied, the 4-bit ripple counter 2 starts a counting operation as shown in FIG.

If the power is turned on and the operation count data is not input to the lower, upper 4 bit comparators 5 and 4 even if the contact aa of the test operation check relay I is turned on, the lower 4 bits The signals applied to the input terminals B _{0 to} B ₃ of the comparator 4 and the entering terminals B _{4 to} B ₇ of the upper 4-bit comparator 5 are both in a low state. Since the signals appearing at the output terminals Q _{0 to} Q ₃ and Q _{4 to} Q ₇ of the bit ripple counters 2 and 3 are also low, the input terminals of the 4 bit comparators 4 and 5 are low. As the signals applied to (A _{0 to} A ₃ ) and (A _{4 to} A ₇ ) are all low and become the same, the upper 4 bit comparator 5 is turned high through the output terminal Q _A = B. Will output the signal of.

Thus the output voltage of the high state, thereby driving the activation oesu check relay (R) as is applied to the base of the transistor (TR ₁₎ thereby the transistor (TR ₁₎ conduction.

Therefore, since the b contact Rb of the start-up confirmation relay R is turned off, the call registration circuit shown in FIG. 2 is cut off and the test operation is not performed.

Therefore, in order to perform the test operation of the elevator, the switch group SWg is operated to apply data on the desired number of operation to the input terminals B _{0 to} B ₇ of the lower, upper 4 bit comparators 4 and 5. The test operation is performed by doing this.

For example, all of the signals applied to the data input terminals B ₀ , B ₁ , B ₂ , and B ₃ of the lower 4-bit comparator 4 by the operation of the switch group SWg are high. The case where the signal input to the data input terminals (B ₄ ), (B ₅ ), (B ₆ ), and (B ₇ ) of the upper 4-bit comparator 5 are set to low state will be described. , The signal applied to the input terminals A _{0 to} A _{7 of the} lower and upper 4 bit comparators 4 and 5 and the signal applied to another input terminal B _{0 to} B ₇ are different from each other. Since the recovery confirmation relay R is not driven, its b contact Rb is turned on.

In this case, assuming that the elevator is located on the reference floor (1st floor), since the elevator is located on the reference floor, the reference floor positioning relay 911 is driven so that its contact point 911 shown in FIG. 2 is turned on.

In such a state, the test operation check relay I is driven to become the A contact Ia of the test operation, and the start count of the check relay R is not driven so that the b contact Rb is turned on and the elevator is turned on. Is on the first floor, a contact 911a of the reference floor positioning relay 911 is turned on, but its b contact 911b is turned off so that the first floor (reference floor) cage call registration relay 511T is turned off, and the other floors. The cage call registration relays 512T to 51nT of the contact call contact relays 512T to 51nT of the contact operation a of the test operation check relay I of the ON state and the contact point b of the operation count check relay R Since power is being supplied through a contact 911a, a call registration is not given to the reference layer (1st floor), and a call registration is given to all other layers.

As such, when the call registration is received, the floor is in a self-holding state, and when the elevator arrives at the floor, the driving of the cage call log relay on the floor is stopped to cancel the call registration.

In this way, when call registration is registered, the a contact generic name (Ta) of the cage call registration relay during the test operation is turned on, and it is the interlock state with the a contact generic name (Cb) of the cage call registration relay during the normal operation. The relay 100 is driven.

Therefore, the driving command relay 100 is turned on while the corresponding cage call lock relay of FIG. 2 is in the driving state, and its contact 100a is turned on so that any one of the rising and falling driving contacts 11 and 12 is turned on. Becomes

If the second floor to n floor call registration relays 512T to 51nT are turned on at the same time by the above assumption, as is well known, the elevator is unidirectional in the order of the second floor to the third floor to the fourth floor to the n-1 floor to the n floor. In this case, the relay 100 is off and the corresponding cage call registration relay is also turned off.

That is, since the 2nd floor to the nth floor cage registration relays 512T to 51nT are turned on at the same time, the lift driving contact 11 is turned on and the elevator performs the lift operation.

If the elevator rises to reach the second floor as described above, the contact a (100a) of the operation command relay 100 is turned off, so the second floor cage call registration relay 512T is also turned off.

At this time, the 4-bit ripple counter 2 counts one pulse at the falling edge where the signal applied to the input terminal CP of the 4-bit ripple counter 2 goes from high to low state. (Q ₀ ) will output a high coral.

Since the output high signal is applied to the input terminal A _{0 of} the 4-bit comparator 4, the 4-bit comparator 4 includes the signal count and the switch group counted by the 4-bit ripple counter 2. It compares with the data signal input by the setting operation of SWg).

At this time, only the signal applied to the input terminal A ₀ by the signal counting one pulse to the input terminals A ₀ , A ₁ , A ₂ , and A _{3 of the} lower 4 bits (4). The signal is applied to the input terminals B ₀ , (B ₁ ), (B ₂ ), and (B ₃ ) of the 4-bit comparator 4 in the high state, the rest of which are all low state, as described above. since both are set to a high state is displayed whose output terminal (Q _a is a low state <B) is displayed, but the signal of the high state, the output terminal (Q _a> B, _a = B Q) signal.

However, since the starter circuit comparison circuit shown in FIG. 1 only needs a high-state coral appearing at the output terminal Q _A = B of the upper 4-bit comparator 5, the output terminal of the lower 4-bit comparator 4 ( Regardless of the signals shown in Q _A > B and Q _A <B), the signal appearing at the output terminal (Q _A = B) of the lower 4 bit comparator 4 is high and the input terminal of the upper 4 bit comparator 5 is high. When the signal applied to (A ₄ to A ₇ ) and the signal applied to the other input terminals B ₄ to B ₇ are the same, the signal appearing on the output terminal (Q ₄ = B) of the upper 4-bit comparator 5 As shown in FIG. 8, the state becomes high.

That is, one clock pulse applied to the clock input terminal CP of the 4-bit ripple counter 2 outputs a high state signal to the output terminal Q _A &lt; B of the lower 4-bit comparator 4. FIG. However, since the output terminal (Q _A = B) of the upper 4-bit comparator 5 is not affected, a low state signal is output to the output terminal (Q ₄ = B) of the upper 4-bit comparator 5, so that 2 The driving of the layer to n layer call registration relays 512T to 51nT cannot be stopped.

Therefore, the elevator operates in response to the third floor call after completing the ascending operation from the first floor to the second floor. As a result, another clock pulse is applied to the input terminal CP of the 4-bit ripple counter 2. since the count, its output terminal (Q ₁₎ There is displayed in the high state signal.

As described above, since the elevator repeats the automatic operation one by one, the 4-bit ripple counter 2 continuously counts the number of driving times, and thus its output terminals Q ₀ , Q ₁ , and Q ₂ . , (Q ₃ ) will output a signal.

In this way, the elevator continues to operate automatically when the number of times of operation until the operation of the top floor is smaller than the data value input by the operation of the switch group SWg (that is, 16 times or less) is continued. When it reaches, all the layers except the top layer, which is the magnetic layer, register cage calling.

Even in the descent operation, the service is performed one by one from the latest floor in the same manner as in the up operation.

At this time, the data values applied to the input terminals B _{0 to} B _{7 of} the lower and upper 4 bit comparators 4 and 5 inputted by the switch group SWg are H, H, H, H, L, and L. , L, L state, so that the signal displayed at the output terminals Q _{0 to} Q ₇ of the 4-bit ripple counters 2 and 3 by the elevator up or down operation is H, H, H, H, L, When L, L, L, and the states coincide with each other, a high state signal is output to the output terminal Q _A = B of the upper 4-bit comparator 5.

Thus the signal of the output high state is because driving a start number of the elevator check relay (R) as thereby is applied to the base of the transistor (TR ₁₎ conducting the transistor (TR ₁₎ standing because his b contact (Rb) are off Cage call during test run could not be registered and operation would be stopped.

Up to now, the case where the elevator is waiting on the reference floor or the top floor at the start of the test operation has been described. Next, the case where the elevator is stopped on the other floors other than the reference floor and the top floor will be described.

In FIG. 2, when the elevator waits on a floor other than the reference floor or the top floor before the test operation starts, the reference floor cage is called once to return to the reference floor, and the automatic operation thereafter is the same as described above.

At this time, in order to perform the reference layer return before the automatic operation starts, the b contact (511T to 51nT) of the 1st to nth layer cage call registration relays (511T to 51nT) is connected in series, and the other floors other than the reference layer and the uppermost layer during the test operation. If it stops in the future, it will not return.

In addition, when canceling the test run, the test run changeover switch SW is turned off to stop the drive of the test run check relay I so that its contact a is turned off so as not to register the cage call during the test run. will be.

The present invention operated as described above inputs the output of the rising and falling driving contactors to the 4-bit ripple counter so as to count the number of start-ups of the elevator, and outputs the output signal of the 4-bit ripple counter to the input terminal of the 4-bit comparator. By inputting predetermined data by the switch group to the other input terminal of the 4-bit ripple counter, the 4-bit comparator finally compares the data values and completes the test operation only when the values match. In this case, it is possible to automatically carry out the up and down operation until the match, so that it is possible to solve the inconvenience of giving the elevator's operation command by manual operation of the sawing material as well as to solve the problem of human and time wasting.
