【Example】

Embodiment 1 FIG. Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numerals 1 to 9 denote the same or corresponding parts as those of the conventional apparatus, and reference numeral 3a denotes an elevator equipment input / output unit for inputting information on the presence or absence of an elevator cage on each floor. Reference numeral 10 denotes a data conversion unit for converting the input information on the presence or absence of the basket into single numerical data indicating the floor on which the basket exists, and 11 determines whether or not the converted numerical data satisfies a preset condition. When satisfied, the data control unit sends the data to the communication unit 6 for transmission to the center device.

Next, the operation will be described with reference to the flowchart of FIG. The monitoring and control of facilities other than the elevator are the same as in the prior art, and a description thereof will be omitted. First, the elevator control panel 9 detects data on the presence or absence of a basket on each floor at regular intervals (S1), and the elevator equipment input / output unit 3a of the local control device 2
To enter. The input data is converted by the data conversion unit 10 into single numerical data indicating the floor where the basket exists (S
2). FIG. 3 shows an example of converting data on the presence or absence of a basket on each floor into numerical data when there are two elevators in a 10F building. Next, the data converted by the data control unit 11 is compared with the data input in the previous cycle, and it is determined whether the data has not changed for a predetermined cycle, that is, whether the basket is in a stopped state. It is determined whether the number has changed by a number or more, that is, whether the basket has moved by a certain amount or more (S3). For example, if data is input in a one-second cycle and the data for five cycles are all the same “5”, it can be determined that the machine is stopped at 5F. Also, whether you have moved a certain amount or more,
For example, 1F, 4F, 7F,
If the data is displayed at 3F intervals as in,..., It may be determined whether the numerical data has changed by 3 or more.

If the set conditions are satisfied (YES in S3)
), The data is transmitted to the center (S4), and the basket position is displayed on the display device of the center device based on the data (S5). If the set conditions are not satisfied (S
3 (NO at step 3), data transmission is not performed, and data detection in the next cycle is awaited. As described above, since the data is transmitted to the center device only when the elevator cage position is stopped or has moved a certain amount or more, the transmission load can be reduced without affecting the monitoring and control of other facilities. Elevator equipment can also be monitored. In addition, when an abnormality such as a power failure or an earthquake occurs, the elevator control can be quickly performed simultaneously with the control of other facilities based on the displayed elevator cage position.

Embodiment 2 FIG. In the first embodiment, the local control device 2 converts the information on the presence or absence of each floor of the elevator into numerical data to determine whether the data should be transmitted to the center device.
As shown in (1), the code conversion unit 10 and the data control unit 11 may be provided in the elevator control panel 9 and the same processing may be performed in the elevator control panel 9. FIG.
Is a flowchart for explaining the operation according to the present example. The processing flow and the setting conditions are exactly the same as those in the first embodiment, but the detection of the basket position (S1) and the conversion of the position data into numerical data (S2) determine whether the numerical data satisfies the setting conditions (S1). The processing in S3) is performed in the elevator control panel. As described above, the data transmission amount between the elevator control panel and the local control device is reduced, and the data transmission load can be further reduced.

Embodiment 3 FIG. In the first and second embodiments, the contact between the elevator control panel 9 and the local control device 2 is connected. However, as shown in FIG. In addition, the equipment communication unit 12 may be added to the elevator control panel 9, and the equipment-side higher-level communication unit 13 may be added to the elevator control panel 9 to send a signal such as a cage position and an abnormality / failure as a communication connection. FIG. 7 is a flowchart for explaining the operation according to this example. After the basket position detection (S1), the equipment-side upper-level communication unit 13
The communication output is performed from (T1) and the communication input is performed by the equipment communication unit 12 of the local control device 2 (T2). After data input, the same processing as in the first embodiment is performed. From the above,
Connection work is easy and various elevator facilities (number, etc.) and data contents can be easily handled.

Embodiment 4 FIG. In the first to third embodiments, the data transmission from the local control device 2 to the center device 5 is performed .
As a condition, the cage position changes more than a certain amount or the cage stops.
To satisfy the setting condition of
In addition, the elevator monitoring screen of the center device is being displayed
Only in such cases, by transmitting data, the amount of transmission can be further reduced. As shown in FIG. 8, a transmission setting processing unit 14 is provided in the data display unit 8 of the center device 5, and when the elevator monitoring screen is displayed, the data management unit 7 is notified that the screen is being displayed. Management unit 7
Sets the upper setting transmission condition 15 provided in the data control unit 11 to “significant” through the center side communication unit 6 and the communication unit 4 of the local control device 2. When the elevator monitoring screen is no longer displayed, the upper-level setting transmission condition 15 is set to “insignificant” by the same procedure.

[0020] Figure 9 is a flow chart for explaining the operation according to the present embodiment, As the flow of the processing is the same as the above embodiment, the determination at S3, the change above a certain cage position
Or the setting condition that the basket is in a stopped state
And the upper setting that the elevator monitoring screen is being displayed
Both conditions that the transmission condition 15 is “significant” are satisfied.
It is determined whether or not. As described above, when the center device is not monitoring the movement of the elevator, there is no need to transmit data, and the transmission amount is further reduced. Also on
In the determination process of S3, the higher-level transmission condition 15 is “
In insignificant ", and the determination condition that is constant per time period
By the addition , even when the monitoring screen of the center device is not displayed, the data is transmitted at a constant time period, so that an emergency can be quickly dealt with.

Embodiment 5 FIG. In the above embodiment, only the elevator cage position data is transmitted from the elevator control panel 9. However, the cage position data is transmitted when the elevator is stopped, and the data of the destination floor (the next stop scheduled floor) is transmitted during the movement. , The cage position of the moving elevator
The data calculated by the data generation processing unit 16 provided in the data management unit of the center device 5 shown in FIG. 10 may be displayed. FIG. 11 is a flowchart illustrating the operation according to this example. First, the basket position data is transmitted during stoppage, and the destination floor is transmitted during movement (U1). At the same time, the elevator control panel 9 detects when the elevator cage has stopped and when it has started moving, and sends the information to the elevator facility input / output unit 3a. Next, the transmitted data is converted into numerical data (U2), and it is determined whether the data is data when the elevator cage is stopped or when movement is started (U2).
3). While moving or stopped (NO in U3) , data transmission to the center device is not performed. If the transmission condition of stopping or moving is satisfied (YES in U3), the data is transmitted to the center device (U4). The center device 5 obtains and displays the elevator cage position from the latest stop floor and the destination floor (U5). FIG. 12 is an elevator cage position change graph. Based on this, the data generation processing unit 16 determines the position M1 after T1 in the movement from the latest stop floor to the destination floor.
Calculates the position MN after TN, and notifies the data display unit 8. As described above, since the communication from the local control device 2 to the center device 5 is performed only when the elevator stops and when the vehicle starts moving, the communication load can be further reduced.

[0022]

As described above, according to the present invention, information on the presence or absence of an elevator cage on each floor is converted into single numerical data indicating the floor where the cage is located, and the data satisfies the set conditions. Then, since the data is transmitted to the center device, the communication volume can be reduced, and the monitoring and control can be performed in the same manner as other equipment. In addition, since the setting condition is that the elevator is in a stopped state or that the elevator is moving by a certain amount or more, there is an effect that the communication load can be reduced. When the display device of the center device is displaying
Only the data is sent to the center device
Thus, the communication volume is further reduced. Also, the destination floor information is input while moving along with the elevator position information, the position during the elevator movement is calculated in the center device, and the calculation result is displayed, so that the transmission of data to the center device is stopped by the elevator. Since only the stop floor information at the time or the next stop floor information at the time of starting the movement is used, the communication load can be further reduced.
