Description

  The present invention relates to a device for checking the function of an elevator call registration device.

  In a conventional elevator signal transmission device, a hall call generated from a hall button provided on each floor is sent to the elevator control panel, and the elevator is controlled to respond to this hall call. And a control signal for generating a control signal for dividing the time-division signal every time the time-division signal is generated by a predetermined number equal to or more than the number of floors where the hall call is generated. Generating means;

  The hall call is registered and the registered hall call signal is counted with respect to the control signal, and the number of occurrences of the time division signal is counted, and the registration of the floor hall call corresponding to the counting result is time division. And a hall call registration means for releasing the registration of the hall call based on a registration cancellation command sent from the control board via the time division signal to the control board (for example, Patent Document 1).

JP 2000-16710 A (Claim 1, FIG. 1)

  In the conventional elevator signal transmission apparatus as described above, it is described that signals are transmitted and received between the hall and the control panel via a time division signal, but in order to check the function of the hall call registration means There is a problem that the clerk must go to each floor each time.

The present invention has been made to solve the above problems, and an object thereof is to provide an inspection device for an elevator call registration device which can easily check the function of the call registration device.

  The inspection device for an elevator call registration device according to the present invention connects a short circuit between the terminals of the call button to short-circuit between the terminals, and transmits a signal transmitted through a transmission line connected to the call registration means. The short circuit is operated by a short-circuit command signal output accordingly.

  In the present invention, since a short circuit is connected between terminals of the call button and this is operated by a short-circuit command signal, the function of the call registration device can be easily checked during installation and maintenance.

Embodiment 1 FIG.
1 to 3 are diagrams showing an embodiment of the first invention of the present invention. FIG. 1 is an overall schematic diagram, FIG. 2 is a circuit diagram of a hall button unit, and FIG. 3 is an inspection processing operation flowchart. The same reference numerals denote the same parts.

  In FIG. 1, a hoisting machine 2 is connected to the operation control unit 1, and a car 3 and a counterweight 4 are driven to raise and lower it. A load detector 5 for detecting a passenger load in the car 3 is installed on the floor of the car 3. A car movement detector 6 that generates a signal 6 a composed of pulses corresponding to the movement distance of the car 3 is coupled to the hoist 2 and connected to the operation control unit 1. In addition, a call registration button unit 7 is installed at each floor hall, and these are connected to a transmission main line 9 via a communication line 8, and the transmission main line 9 is connected to the operation control unit 1.

  In FIG. 2, the N-floor hall call registration device 11 is connected to a communication line 8 and a call button 12 is connected. Moreover, it is connected to the response lamp 14 through the transistor 13 which is turned on by the response lamp lighting signal 11a of the N floor hall call registration device 11. A gate circuit 15 is connected between the terminals of the call button 12, and the gate terminal is connected to the Nth floor hall call registration device 11. The gate circuit 15 becomes conductive when the short-circuit command signal 11b becomes “1” at the gate terminal.

Normally, since the short circuit command signal 11b from the Nth floor hall call registration device 11 is “0”, the gate circuit 15 is off.
In this state, when the call button 12 is pressed and the call signal 12a is output, the N-floor hall call registration device 11 registers the call, converts it into a transmission signal, and converts the communication line 8 and the transmission trunk line 9 into a transmission signal. Is sent to the operation control unit 1 via. When the hall call is registered, a response lamp lighting signal 11a is output from the Nth floor hall call registration device 11, the transistor 13 is turned on, and the response lamp 14 is lit.

  When a short-circuit command signal is output from the operation control unit 1 at the time of inspection, the short-circuit command signal 11b from the N floor hall call registration device 11 is “1”, so the gate circuit 15 is turned on and the terminal of the call button 12 The space is short-circuited. Thus, even if the call button 12 is not pressed, the call signal 12a is output.

Next, the inspection operation of the call button 12 will be described with reference to FIG.
In step S1, the Nth floor short-circuit command signal 11b is set to "1". In step S2, the system waits for the time required for transmission of the output signal and transmission of the input signal. When the predetermined time has elapsed, the process proceeds to step S3, and it is determined whether the call signal 12a of the call button 12 on the N floor is on. If it is on, the process proceeds to step S4, and the result determination flag FLAG1 is set to "1". If it is off, the process proceeds to step S5, and the result determination flag FLAG1 is set to "0".

Thereafter, the process proceeds to step S6, and the N-th floor short-circuit command signal 11b output in step S1 is set to “0”.
Here, steps S1 to S6 constitute call signal checking means.
In this way, when the short-circuit command signal 11b for the call button 12 on the N floor becomes “1”, the gate circuit 15 is turned on and the terminals of the call button 12 are short-circuited. However, it is possible to easily check the hall call registration device 11 during installation and maintenance.

Embodiment 2. FIG.
4 and 5 are internal process operation flowcharts of the operation control unit showing an embodiment of the second invention of the present invention, FIG. 4 is a check preparation operation flowchart of the call registration device, and FIG. 5 is a check of the call registration device. It is an operation | movement flowchart. 1 and 2 are shared by the second embodiment.

(1) Inspection preparation operation (Fig. 4)
In step S11, it is determined whether a call inspection switch (not shown) is turned on. If turned on, the process proceeds to step S12. If it is in the off state, the process jumps to step S18 to set the inspection operation flag ST to “0”. On the other hand, if it progresses to step S12, the state of the check operation flag ST will be confirmed. That is, it is determined whether inspection is started (ST ≠ 0). Immediately after the call inspection switch is turned on, since the inspection operation flag ST = 0, the process proceeds to step S13. When the inspection operation flag ST ≠ 0, the process ends.

  In step S13, it is determined whether the car 3 is stopped at the terminal floor. If it is determined that the vehicle is stopped at the lowest floor, the process proceeds to step S14, where “1” is set in each of the inspection floor flag N and the inspection operation flag ST, and the process proceeds to step S16. If it is determined that the vehicle is stopped on the top floor, the process proceeds to step S15, where the number of floors on the top floor is set in the inspection floor flag N and “2” is set in the inspection operation flag ST. Thereafter, the inspection mode flag MD is set to “0” in step S16.

  On the other hand, if it is determined in step S13 that the vehicle is not stopped at the terminal floor, the process proceeds to step S17, where a traveling command to the terminal floor closer to the current position of the car 3 is output. " Thereby, the car 3 travels to the terminal floor and can proceed from step S13 to step S14 or step S15.

(2) Inspection operation (Fig. 5)
It is judged from the inspection operation flag ST whether the call inspection has been started in step S21. If the inspection operation flag ST is “0”, the inspection is not started yet, and the process ends. If the inspection operation flag is other than “0”, the inspection is started, and the process proceeds to step S22. In step S22, it is determined whether the car 3 is waiting for door closing. For example, if the car is waiting for door closing on the first floor, the process proceeds to step S23.

  In step S23, the call inspection direction is determined by the inspection operation flag ST. If the check operation flag ST is “1”, the car 3 is on the lowest floor, and is checked from the up call button. In step S24, the inspection floor flag N is sequentially added to “2” at first. In step S25, it is determined whether the inspection floor N has reached the top floor. In this case, since it is not the top floor, the process proceeds to step S27, and a call inspection process as shown in FIG. Since the state is the same as when the call button 12 is actually pressed, the car 3 runs to the second floor if it is normal.

  In step S28, it is determined whether the car 3 has traveled. If the car 3 has traveled, the process proceeds to step S29 to determine whether the inspection floor N and the car position floor N1 are equal. Here, N1 is the floor number indicating the position of the car 3 calculated from the output signal 6a of the car movement detector 6. If the inspection floor N and the car position floor N1 are the same, it is determined that the floor value setting of the Nth floor hall call registration device 11 is also normal, and the process proceeds to step S30, where the normal signal “1” is Nth in the inspection result flag ERF. Set.

  If the inspection floor N and the car position floor N1 are not the same, it is determined that the floor value setting of the N-floor hall call registration device 11 is not correct, and the process proceeds to step S31. "Is set. If it is determined in step S28 that the car 3 does not travel, the process proceeds to step S32, where it is determined that the call registration button unit 7 is abnormal, and an abnormality signal “3” is set to the Nth inspection result flag ERF.

  When the above operation is repeated and the inspection floor N reaches the first floor before the top floor, “1” is added to the inspection floor N in step S24, and the process proceeds from step S25 to step S26. In step S26, the inspection operation flag ST is set to “2”, and next, the down call button is inspected. In addition, since “1” is added to the inspection mode flag MD in step S26, the value becomes “1”. Thereafter, the process proceeds to step S38, and the down button on the top floor is checked.

  The down button is also inspected in the same manner as the up button, and when it reaches the second floor, the inspection floor N is subtracted in step S35, and N = 1. In step S36, since N = 1, the process proceeds to step S37. In step S37, the inspection operation flag ST is set to “1”, and the up button is inspected next. Further, since “1” is added to the inspection mode flag MD, the value becomes “2”. And it progresses to step S27 and the up button of the lowest floor is inspected.

After the inspection, the process proceeds to step S33, and the inspection mode flag MD is confirmed. If the inspection mode flag MD is “2”, it means that the reciprocating operation has been performed, so that the process proceeds to step S34, the inspection operation flag ST is reset, and the call button inspection operation is terminated.
Thereafter, the operator confirms the value of the inspection result flag ERF, and if all the values are “1”, it can be determined that there is no abnormality. If the values “2” and “3” are included, an abnormal floor can be quickly found and it can be easily determined whether the setting of the call registration button unit 7 is wrong or a failure.

Here, steps S21 to S34 constitute call signal checking means.
In this way, the check of the call button is performed by reciprocating the car 3 between the lowermost floor and the uppermost floor, and every time the inspection of one floor is completed, the short circuit of the call button 12 on the next floor is completed. Since the short-circuit command signal 11b is output to the (gate circuit) 15 and the state of the call signal 12a is determined, it is possible to easily find a setting error of the N floor hall call registration device 11.

Embodiment 3
FIG. 6 is an inspection operation flowchart of the call registration device showing the internal processing of the operation control unit showing one embodiment of the third and fourth aspects of the invention. 1 to 5 are shared by the third embodiment.
In step S41, it is determined whether the output value of the load detector 5 installed in the car 3, that is, the load value in the car has increased. If the load value increases, the call inspection process is not executed and the process is interrupted. If the load value is other than the above, the process proceeds to step S42.

In step S42, the number of call registrations is confirmed. If the registered number is 1 or less, the process proceeds to step S43, and a call inspection process as shown in FIG. 5 is executed. If the registered number is 2 or more, the process proceeds to step S44, and the call registration other than the inspection floor N is canceled.
Here, step S41 constitutes inspection interruption means, and steps S42 to S44 constitute call registration cancellation means.

  Thus, since the inspection operation is interrupted when the car load value increases, the inspection operation can be interrupted even if a general passenger gets on board by mistake during the inspection operation. Also, if the number of registered calls exceeds 2 during the inspection operation, the registration of calls other than the inspection floor will be canceled, so even if the call is actually registered with the call button on the other floor during the inspection operation. Since the call registration is canceled, the call check operation can be prevented from being hindered.

  In each of the above embodiments, the inspection of the N-floor hall call registration installation 11 has been described. However, the present invention is not limited to this, and the present invention is also applicable to the inspection of a destination call button (not shown) provided in the car 3. It is obvious to get.
