When a passenger presses the destination floor button 51, a destination floor registration request signal is sent from the car terminal device 4 to the single-elevator control device 1 . After the single-elevator control device 1 receives the destination floor registration request signal through the multiple transmission line 2, as described later, the time when the destination floor button 51 indicated by the destination floor registration request signal is pressed is the press input. time, judge whether the passenger has pressed the destination floor button 51 intentionally, when it is judged that the passenger has pressed the destination floor button 51 intentionally, carry out the call registration of the destination floor, generate the operation control that makes the elevator car 3 travel to the destination floor instruction. The single-elevator control device 1 transmits to the car terminal device 4 an instruction command signal indicating that a destination floor call has been registered. After the car terminal device 4 receives the instruction command signal through the multiplex transmission line 2, a light emitting device such as an indicator light or an LED built in the destination floor button of the registered call is turned on to indicate that the destination floor call has been registered.

As will be described later, the single-elevator control device 1 determines that a passenger has intentionally pressed the destination floor button 51 when it determines that the destination floor button 51 is pressed and inputted for a predetermined time or longer indicated by the destination floor registration request signal. The value of this predetermined time is changed according to the congestion situation in the elevator car. Thereby, it can be determined with high accuracy whether or not the passenger has intentionally pressed the destination floor button 51 . In addition, in the present embodiment, the single-elevator control device 1 judges the congestion state in the elevator car 3 based on the load weight signal indicating the load weight data of the elevator car 3 detected by the load detection device 6 .

Judging the crowded situation in the elevator car 3, the output changing part 13 outputs the specified input recognition time as the reference of the pressing input time of the destination floor button 51 for judging whether the passenger has pressed the destination floor button 51 intentionally, and according to The value of the input recognition time of its output is changed according to the congestion situation in the elevator car, and the single-elevator control part 14 is used to control each part. The single elevator control part 14 also has the function of generating control commands for controlling the speed and position of the elevator car, the opening and closing of the elevator doors, and the display and guidance devices and voice guidance devices installed in the elevator car or in the elevator hall.

When the communication part 20 of the single-elevator control device 1 receives the destination floor registration request signal transmitted from the car terminal device 4 via the multiple transmission line 2, the single-elevator control part 14 detects the registration request signal based on the received destination floor. The pressed input time (that is, the input detection time) and the input recognition time output by the output change part are compared. As a result of the comparison, when the input detection time is above the input recognition time, the single-elevator control part 14 regards the destination floor as a call Registration is performed, and an operation control command for allocating the elevator car to the destination floor where the call is registered is generated. When the communication part 20 receives the load weight signal sent from the car terminal device 4 via the multiple transmission line 2, the single-elevator control part 14 extracts the load weight data in the elevator car 3 from the received load weight signal, and The degree of congestion in the elevator car is detected based on the extracted load weight data. The output changing section 13 outputs the value of the input recognition time according to the detected degree of congestion. Furthermore, the single-elevator control section 14 compares the input detection time with the input recognition time output from the output change section 13, and judges whether or not to register the destination floor as a call.

The single-elevator control unit 14, the output changing unit 13, and the congested state judgment unit 12 are constituted by an arithmetic processing unit such as a single or individual microcomputer, and operate by executing programs corresponding to various functions by the arithmetic processing unit. In addition, the elevator control device drives the hoist that is wound with the sling that suspends the elevator car according to the operation control command from the above-mentioned single-elevator control device, and distributes the elevator car to the destination floor where the call is registered (this part is not shown in the figure). Show).

When the car terminal device control part 15 in the car terminal device 4 detects that the destination floor button 51 is pressed, the destination corresponding to the pressing time is sent from the communication part 21 to the single elevator control device 1 via the multiple transmission line 2. Floor registration request signal. Furthermore, the car terminal device control section 15 transmits to the single-elevator control device 1 a load weight signal corresponding to the load weight data in the elevator car detected by the load detection device 6 . When a call is registered, the single-car control section 14 in the single-car control device 1 transmits an instruction command signal from the communication section 20 to the car terminal device 4 via the multiple transmission line 2 . When the communication unit 21 of the car terminal device 4 receives the instruction command signal, the car terminal device control unit 15 controls the lighting of the light emitting device built in the destination floor button 51 .

The car terminal control unit 15 is constituted by an arithmetic processing unit such as a microcomputer, and the arithmetic processing unit operates by executing a program stored in the storage unit 16 corresponding to the function of the car terminal control unit 15 . In addition, the car terminal device control section 15 also has the function of receiving instructions from the single-elevator control device 1 to control the opening and closing of the elevator doors, and the function of controlling the display guidance device and voice guidance device installed in the elevator car.

The car terminal device control section 15 may also have an output change signal indicating that the input recognition time value has been changed to a value corresponding to the congestion situation output from the output change section 13 of the single-elevator control device 1 or the single-elevator control section 14. The judging result signal of the crowded situation is based on the program stored in the storage unit 16, which controls the output devices such as the display guidance device and the voice guidance device installed in the elevator car to inform the function of the crowded situation.

FIG. 3 is a flowchart of the flow of processing executed by the single-elevator control device 1 .

The single-elevator control device 1 acquires input signals from various I/Os (step SA10), then executes destination floor button input detection timing processing (step SA20), and destination floor button input processing (step SA30). Thereafter, the single-elevator control device 1 determines the service floor according to the acquired I/O status (step SA40), and generates a floor plan for controlling the speed and position of the elevator car, the opening and closing of the elevator door, and the floor information set in the elevator car or elevator. The operation control commands of the display guidance device and the voice guidance device, etc. in the lobby (step SA50). The single-elevator control device 1 repeatedly executes the processing of the above-mentioned step SA10 to step SA50 by the operating system (OS) in the single-elevator control device at regular intervals.

Fig. 4 is a flowchart showing details of the destination floor button input recognition time setting process (SA20) in Fig. 3 .

The single-elevator control device 1 periodically acquires and reads the load weight data detected by the load detection device 6 in the car indicated by the load weight signal transmitted from the car terminal device 4 (step SB10 ). Next, the single-elevator control device 1 judges whether the interior of the elevator car 3 is in a congested state based on the read loading weight data (step SB20). In this embodiment, the ratio of the loading weight value shown by the loading weight value (that is, loading weight data) to the maximum loading weight value is used as the degree of congestion, and by judging whether the degree of congestion is at a specified value (in this embodiment 80%) or more to judge whether the elevator car 3 is in a crowded state. The judgment of the degree of congestion in step SB20 can be set to calculate the ratio of the value of the loaded weight to the value of the maximum loaded weight, and judge whether the calculation result is above 80%, thereby judging the degree of congestion, or it can also be set to directly The value of the loaded weight is compared with the value of 80% of the maximum loaded weight, and it is judged whether the loaded weight is above 80% of the maximum loaded weight, thereby judging the degree of congestion. Here, the judgment value of the degree of congestion of 80% is an example of a value of the degree of congestion with a relatively high possibility that passengers accidentally touch the destination floor button, and the judgment value of the degree of congestion can be determined according to the size and shape of the elevator car, The position of the operation panel, the maximum loading weight, the rated number of passengers, the actual situation of the crowded state, etc. are set appropriately.

When it is judged that the degree of congestion is less than a predetermined value, that is, when it is less than 80% (step SB20 is "No"), the single-elevator control device 1 sets the input recognition time of the destination floor button used in step SA30 of FIG. 3 to Standard data (step SB30). On the other hand, when it is judged that the degree of congestion is 80% or more (step SB20 is "Yes"), the single-elevator control device 1 sets the input recognition time of the destination floor button to specific data that is a time value longer than the standard data. (step SB40). After executing step SB30 or step SB40, the single-elevator control part 14 proceeds to the process of step SA30 in FIG. 3 .

As described above, when in a crowded state, the input recognition time is set to a time value longer than the time when it is not in a crowded state, so as to prolong the pressing input time of the destination floor button required for call registration, thereby making it possible to reliably It can accurately identify whether it is the passenger's intentional operation or misoperation.

Fig. 5 is a flowchart showing details of the destination floor button input process (SA30) in Fig. 3 .

The single-elevator control device 1 judges whether the value of the input detection time of the destination floor button indicated by the destination floor registration request signal is within the destination floor button input recognition time setting process shown in FIG. 4 . The value of the input recognition time is greater than or equal to (step SC10). When it is judged that the value of the input detection time of the destination floor button is smaller than the value of the input recognition time of the destination floor button (step SC10 is "No"), the single-elevator control device 1 ends the flow process of Fig. 5 and enters the process of Fig. 3 Processing of step SA40. When it is determined that the value of the input detection time of the destination floor button is greater than or equal to the value of the input recognition time (YES in step SC10), the single-elevator control device 1 registers the destination floor indicated by the destination floor registration request signal (also Exactly the destination floor that the passenger inputs by the destination floor button) is registered as a call (step SC20). After this step SC20 ends, the single-elevator control device 1 advances the process to step SA40 of FIG. 3 .

In this embodiment, according to the frequency of erroneous operations unintentionally caused by the passenger's body or belongings in contact with the destination floor button when the passenger is not in a crowded state, or the pressing time of the destination floor button at the time of erroneous operation, the input The standard data of the recognition time is set to a value that prevents the destination floor from being registered as a call by an erroneous operation. On the other hand, when in a crowded state, compared with a non-crowded state, the frequency of erroneous operations becomes higher, and the average value of the press input time of the destination floor button at the time of erroneous operations becomes longer, so the specific time for input recognition The data is set to a value longer than the standard data. As a result, in a congested state, although it takes longer to register a call than in a non-congested state, it is possible to prevent a destination floor from being registered as a call due to an erroneous operation. In addition, in the non-congested state, the time required for call registration can be set to be the same as the standard data value, so it is possible to suppress a decrease in passenger convenience. In addition, in this embodiment, when registering a destination floor, no special action is required for the passenger, nor is there any need to operate a special device, so the convenience of the operation of the destination floor button will not be reduced.

In this embodiment, the congestion status in the elevator car is judged based on the load weight data detected by the load detection device. The input detection time of the ground floor button is used to identify whether it is a reference input recognition time of misoperation, thereby changing the operation time of the destination floor button required for the call registration of the destination floor. This prevents unnecessary registration of destination floor calls when a passenger or passenger's belongings touches the destination floor button inadvertently and makes an erroneous operation during a congested time period. In addition, in this embodiment, the operation method of the destination floor button is the same as the original pressing action, so the convenience and operability of passengers will not be reduced, and the operation efficiency of elevator operation service can be improved.

The present invention is not limited to the above-described embodiments, and various modifications may be included. For example, the above-mentioned embodiments are used to explain the present invention in detail in an easy-to-understand manner, but it does not mean that the present invention must have all the explained structures. In addition, it is possible to add, delete, or replace a part of the configurations of the embodiments with other configurations.

For example, the degree of congestion in the elevator car can also be detected from the image of the camera in the elevator car. At this time, the degree of congestion can be detected by obtaining the occupancy rate and the number of passengers in the elevator car interior space by image processing. Alternatively, the distribution of the load may be measured, and the degree of congestion may be detected from the area to which the detected load acts.

The present embodiment can also be applied to elevator equipment in which the destination floor input device is installed in the elevator lobby. At this time, the degree of congestion in the area of the elevator lobby where the destination floor input device is installed is detected.

In this embodiment, the criterion for judging the degree of congestion is divided into two stages, one is less than 80%, and the other is above 80%, but it is not limited thereto, and it can also be set to more than three stages.

The signal transmission of the multiplex transmission line 2 may be wired transmission, and may also be wireless transmission.
