KR960011573B1 - Elevator call registration cancellation method - Google Patents

Abstract

The method is for cancelling the wrong calling register by receiving a cancel signal which is registered again in the state that a gate button lamp is lit by recognizing that a call register is generated through an interface IC, by separating the input/output signal. The method comprises a calling registering process(S1-S6), a first cancelling process(S1,S7) and a second cancelling process(S1,S7-S9).

The present invention relates to a call registration technology of an elevator, and in particular, in registering a desired floor by using a call registration button installed in a cage, a call registration of an elevator is made to be suitable for canceling an accident when an unwanted floor is called. It is about how to cancel.

1 is a block diagram of a general call registration of an elevator, as shown therein, an interface integrated device 1 which detects on and off of cage call buttons SW _{1 to} SW ₈ and outputs a corresponding signal; The central processing unit 2 outputs data for turning on the corresponding cage button lamp in accordance with the signal input from the interface integrated device 1, and the central processing unit 2 collectively controls the system, and from the central processing unit 2 via the data bus. The base driver 3 outputs a base driving signal through a corresponding port according to the input data, and controls the on / off of the gate button lamps LAM _{1 to} LAM ₈ according to the signal input from the base driver 3. It is composed of a transistor array (4), the operation thereof will be described in detail with reference to Figures 2 to 5 as follows.

For example, when the passenger presses the cage call button SW ₁ , the interface integrated device 1 detects this and transmits the detection signal to the central processing unit 2. The circuit as shown in FIG. 3 is provided with the number corresponding to the cage call buttons SW _{1 to} SW ₈ , which will be described below with reference to one example.

When the passenger presses the cage call button (SW ₁ ) and the switch (SW ₁ ) is turned on, the power terminal voltage (24V) is the resistance (R ₁ ), the diode (D ₁ ) and the resistor (R ₂ ), the switch (SW ₁ ) Since the current flows to the ground side sequentially, the voltage supplied to the non-inverting input terminal of the comparator CP is lower than the reference voltage V _ret supplied to the inverting input terminal of the comparator CP. Low is output to the side.

Accordingly, the central processing unit 2 recognizes that the current cage call button SW ₁ is pressed and outputs the data A _0- A ₂ as shown in FIG. 4 to the base driving unit 3 to light the corresponding lamp. In this case, the data A _0- A ₂ is output as ₀ , and only data D ₀ is output high among the output data D _0- D ₇ of the base driver 3.

Accordingly, the transistor Q ₄ is turned on in the transistor array 4, that is, the transistor Q ₁ among the plurality of transistors configured as shown in FIG. 5, and accordingly, the corresponding lamp among the plurality of gate button lamps LAM _{1 to} LAM ₈ is turned on. LAM ₁ ) is turned on so that the collector potential of the transistor Q ₁ goes low, and this row is supplied to the central processing unit 2 to recognize that the cage call button SW ₁ remains on even after being turned off. do.

However, in such a conventional circuit, once the cage call button is pressed, the corresponding gate button lamp is turned on, and a signal indicating that the gate button lamp is turned on is input through the data bus which transmits the output signal of the interface integrated device. Thereafter, even if the cage call button is pressed again, the central processing unit cannot recognize this, and even if the call registration is incorrect, it cannot be canceled, thereby causing a defect that wastes time and energy.

In order to solve such a defect, the present invention recognizes that call registration has occurred through the interface integrated device by separating and managing input and output signals, and accepts a cancellation signal registered again even when the gate button lamp is turned on to register an incorrect call. Invented so that it can be released, it will be described in detail by the accompanying drawings.

FIG. 6 is a control block diagram of an elevator to which a call registration / cancellation method of the present invention is applied. As shown in this example, an interface for detecting on / off of cage call buttons SW _{1 to} SW ₈ and outputting a corresponding signal is shown in FIG. The central processing unit 12 for controlling overall operation of the system by determining cage call registration / cancellation based on the integrated device 11 and the current output state and the signal input from the interface integrated device 11. And a base driver 13 outputting a base drive signal through a corresponding port in accordance with data inputted from the passage central processing unit 12 through a data bus, and a gate button according to a signal input from the base driver 13. It consists of a transistor array 14 for controlling the on and off of the lamps LAM _1- LAM ₈ , which is described in detail with reference to FIGS. This is as follows.

The time that the passenger keeps pressing the cage call button is at least 200MS ~ 300MS. During this time, the central processing unit 12 can check the button input dozens of times so that the passenger can press the cage call button (SW) once. The device 12 repeatedly registers and cancels the system several times, and the system becomes unstable. In order to prevent this, the system sets the validity period of a predetermined period, receives the registration, and inputs the same validity period while setting 1 to the output. The program should be modified to ignore the above, and this algorithm will be described with reference to FIG.

Will be described with any more of the example, the gate button on the output data of the off state of the lamp (LAM) on, the output of which outputs the data according to the off input buffer (X ₅₁₁₎ of data and cage button lamp (LAM) of If the output data of the output buffer Z ₅₁₁ is AND-combined, 1 is determined as cancel registration, and 0 is determined as registered or unregistered (S ₁ ).

First, in the state where there is no registration and there is no output, the process of confirming that the passenger misregisters the call is described. If the operation result is 0 in the first step S ₁ , the operation of the input buffer X ₅₁₁ is performed. Check if the most significant bit MSB is set, and if it is reset, it is judged as non-registration, and the registration recognition flag (Bit_iND) is cleared to accept the next call registration. If the MSB is set, it is determined as registered and then registered. If it is set after checking whether or not the authorization flag (Bit_iND) is set, it is regarded as the data that is checked and input several times for one button input.If it is reset, it is regarded as the first registration that is entered, that is, the new registration that can be recognized. Set the registration flag (Bit_iND) and set the MSB to the output buffer (Z ₅₁₁ ) to turn on the gate button lamp (LAM). And end the task.

Second, when a call registration occurs and the process of checking that the passenger keeps pressing the call registration button (SW) while the lamp is turned on and describes the process of processing the same, if the end combination result of the input and output buffer (Z ₅₁₁ ) is 1 It is determined that the registration registration flag (Bit_iND) is determined as a cancellation registration. As a result, if the passenger sets the cage call button (SW) as soon as the user presses the cage registration button, he / she keeps pressing to cancel it. It is judged and terminated as it is. (S ₇ )

Third, when the call registration occurs and the process of the call registration is canceled by canceling the pre-registered call registration while the lamp is turned on, this is the registration recognition flag Bit_iND in the seventh step S ₇ . ) Is reset, and the output buffer Z ₅₁₁ is cleared, and the registration acknowledgment flag Bit_iND is set and terminated. This process is a process for the passenger pressing the cage call button SW again within a predetermined time in order to cancel it from the registered state once.

As described in detail above, the present invention manages the input and output data for the call registration separately, and shortens the operation time by enabling the user to cancel the mistaken registration in the state where the cage call registration is completed once by using a predetermined program. It can save energy.
