Abstract

PROBLEM TO BE SOLVED: To set a timepiece inside an elevator controller to the reference time of a building. SOLUTION: This controller is installed in a building equipped with a master timepiece 5 that serves as the reference of the time of timepieces in the building and with an in-building network 4 over which information about the master timepiece is transmitted. In this case, a network connection means 3-1 is provided for connection to the in-building network. The network connection means 3-1 gains time calibrating information from the master timepiece 5 via the in-building network 4 to calibrate the time of a timepiece means 3-2. The timepiece means 3-2 outputs time information inside the elevator controller 3. Therefore, the timepiece inside the elevator controller can be set accurately to the master timepiece in the building in which the device is installed. A device exclusively for calibrating the timepiece in the elevator controller can be omitted.

2. Description of the Related Art In an elevator control apparatus, a control method is switched according to time, traffic demand for each building is learned, or time information is displayed to an elevator user using a display. , A clock is provided.

[0003] In order to calibrate the time of this watch, for example, Japanese Patent Application Laid-Open No. 61-174076 discloses a method of receiving a standard radio wave and correcting the time. A method for correcting the time of the elevator control device using a clock and a method for correcting the time from a monitoring center via a telephone line are disclosed in Japanese Patent Application Laid-Open No. Hei 7-315707.

As a method of adjusting the clock of an apparatus to a reference clock, a number of computers are connected to a network, one computer becomes a master for transmitting reference time information, and another computer becomes a master clock via the network. A method of adjusting the time of the own clock is used. An example of this is disclosed in JP-A-63-8813.

[0005]

In the prior art described above, a method of installing a clock correction device / monitoring device dedicated to an elevator is used to calibrate a clock of an elevator control device. However, a network that can also be used for the purpose of correcting the clock may be installed in the building. However, in the above-described conventional technology, the clock of the elevator control device is utilized by utilizing the clock information transmitted to this network. There was no idea to fix.

[0006] In view of this, it is an object of the present invention to provide an elevator control device and network connection means for connecting to a building network.

Another object of the present invention is to synchronize the time of the clock of the elevator control device with the time calibration information of the master clock transmitted to the network.

[0008]

In order to achieve the above-mentioned object, a master clock serving as a time reference for a clock in a building and a network in the building to which information of the master clock is transmitted are installed in a building. An elevator control apparatus includes a clock unit for outputting time information and a network connection unit for connecting to a building network.

The network connection means operates to acquire time calibration information from the master clock via the in-building network and to calibrate the time of the clock means.

The clock means outputs time information inside the elevator control device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a system configuration diagram of an embodiment of the present invention.

In the embodiment of the present invention, the system comprises a car 1, a hall calling means 2, a control device 3, a building network 4, and a master clock 5. The control device 3 includes a network connection unit 3-1, a clock unit 3-2, and an operation control unit 3-3.

Information such as the call registered in the hall call means 2 provided on each floor, the position and state of the car 1, and the registration of the destination floor in the car are transmitted to the control device 3, and the operation in the control device 3 is performed. The control means 3-3 determines the operation of the car and operates the car 1. Here, the operation control means 3-
Since the operation of 3 is widely and generally used,
Detailed description is omitted.

The master clock 5 is connected to the network 4 in the building in order to match the clocks of a number of computers (not shown) connected to the network 4 in the building, or broadcasting equipment in the building for notifying time signals such as work and lunch. Transmit reference time information. A number of computers (not shown), broadcasting equipment in a building, and the like adjust the time of their own clock to a master clock 5 via a network 4 in the building. If necessary, the master clock 5 is calibrated by a higher master clock connected to a network outside the building. The in-building network 4 is used for various other communications such as a large number of computers (not shown).

In the embodiment, the master clock 5
Has been described as being directly connected to the in-building network 4, but the present invention can be implemented as long as the information of the master clock 5 is transmitted to the in-building network 4. It may be installed outside via a.

The network connection means 3-1 provides a physical connection with the building network 4 and an interface as software, acquires time calibration information from the master clock 5 via the building network 4, and -2
Calibrate the time.

The clock means 3-2 outputs time information used in the control device 3. The control device 3 switches the control method of the operation control means 3-1 based on the time information,
The traffic demand for each building is learned, or time information is displayed to the elevator user using a display.

FIG. 2 is a flowchart of the time calibration program 10 for calibrating the time of the clock means 3-2 in the control device 3.

The time calibration program 10 is a program that is started periodically, such as once a day.

The time calibration program 10 includes a step 10
At -1, the master clock 5 is requested for calibration time information.

At step 10-2, the calibration time is obtained from the master clock 5, and at step 10-3, the time of the clock means 3-2 in the control device 3 is calibrated.

In FIG. 2, the method of requesting the calibration from the control device 3 has been described. However, when the master clock 5 broadcasts the reference time information simultaneously, the network connection means 3-1 broadcasts the time calibration program 10. As a program to be started by interrupt processing when a
-2, by executing step 10-3, the time of the clock means 3-2 in the control device 3 may be calibrated.

In this embodiment, the elevator 1
Although the description has been made by taking one control device as an example, in a system including a plurality of elevator control devices and a group management control device that controls the operation of the elevators, a network connection means is provided in the group management control device and It is of course possible to obtain the time information from the network in the building and to calibrate the clocks of the group management control device and each control device.

According to the embodiment of the present invention, since the time of the clock in the elevator control device is set to the master clock, the master clock connected to the building network is shifted from the higher standard time. Therefore, even when the chime in the building is notified of the deviation, there is an effect that the operation of the elevator can be changed in conjunction with the master clock in the building.
