Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in a remote monitoring apparatus for elevators and buildings, and is particularly suitable for remote monitoring when monitoring and controlling elevators and buildings using wireless data transmission means such as mobile phones. Regarding the system.

[0002]

2. Description of the Related Art Conventionally, when a device such as a mobile phone for making a telephone call or transmitting / receiving data wirelessly has become widespread, an elevator or building equipment is monitored and controlled at a monitoring center, and an alarm is issued due to a device abnormality. Japanese Patent Publication No. 6-34278 proposes a remote monitoring device that transmits the content of a notification to a mobile terminal device carried by a maintenance person who is traveling in the area.

[0003]

Here, even when there is no notification or the like to the monitoring terminal device, the operation status of the elevator or building equipment is investigated and the control of the elevator or building equipment is carried from the portable terminal device. There is a growing need to make phone calls. In this case, it is conceivable that the portable terminal device directly communicates with the monitoring terminal device via the mobile phone to perform data communication with the monitoring terminal device.

However, it has been pointed out that when data communication is carried out using a mobile phone or the like, a transmission error may occur during data communication due to fluctuations in the propagation state of radio waves and electromagnetic noise from the surroundings. This transmission error is different in nature from the transmission error that usually occurs on telephone lines. Therefore, when the error detection / correction method used between the terminal device and the monitoring center in the conventional remote monitoring system is used, It is difficult to properly detect and correct the generated transmission error. On the other hand, an error detection / correction method specialized for wireless data transmission has been proposed and put into practical use as a product.However, if this method is adopted, it will be applied to all monitoring terminals to be connected to the mobile terminal. Since this error detection / correction method must be implemented, the cost will increase considerably.

Further, with the recent increase in the number of monitoring points of elevators and buildings, it is conceivable that the amount of data during communication will increase and the communication time will increase. If the communication time becomes long, there may occur problems such as an increase in communication cost and an increase in communication failure rate due to a communication error.

An object of the present invention is to perform remote monitoring which does not impair the reliability of communication even when communication is carried out from a mobile terminal to a monitoring terminal and which can prevent a significant increase in the cost of adding communication equipment. To provide a system.

[0007]

In order to achieve the above object, the present invention provides a function of monitoring the status of equipment of elevators and buildings and transmitting the status data via a telephone line, and a function of transmitting the status data via the telephone line. And the monitoring terminal which has the function of controlling the equipment of elevators and buildings according to the transmitted control data, the status data and control data are transmitted and received via a telephone line to display the status of the equipment of elevators and buildings. A mobile terminal for creating control data, a wireless data transmission means connected to the monitoring terminal and having a function of transmitting the status data and control data via a wireless telephone line, and the wireless data transmission means. A communication relay device having a communication means and a communication means for communicating with the monitoring terminal device, wherein the communication relay device exchanges data between the monitoring terminal device and the mobile terminal device. When receiving the state data collection command or control data transmission command from the portable terminal device via the wireless data transmission means, the connection with the wireless data transmission means is disconnected, and then the communication means is used. The state data and control data are transmitted to and from the monitoring terminal device, and after the transmission of the state data and control data is completed, the portable terminal device is called using the wireless data transmission means and collected by the communication relay device. It has a function of transmitting the transmission result of the state data and the control data to the portable terminal device.

[0008]

In the present invention, when the communication relay device receives a communication request from the mobile terminal device to the monitoring terminal device via the mobile phone, the communication relay device disconnects the line with the mobile phone after the communication is completed and then communicates with the monitoring terminal device. Communication is performed via the means to collect operating status data from the monitoring terminal device, send control data to the monitoring terminal device, and confirm the operation. After the communication of the operating status data and the control data is completed, the communication relay device processes the operating status data and the control data such as compression so as to be suitable for wireless communication, and then requests the communication in advance. The telephone is called, the processed data is transmitted to the mobile terminal device via the mobile phone, and the line is disconnected after the transmission is completed. Therefore, it is possible to obtain a similar communication result in a time shorter than the time required for actual communication with the monitoring terminal device, and when the communication speed of the mobile terminal device is sufficiently higher than the communication speed with the terminal, The communication time can be greatly shortened and the communication cost can be reduced. Further, according to the present invention, by installing a communication relay device having both a communication means with a conventional monitoring terminal and a communication means via a mobile phone, it is possible to change to the conventionally installed monitoring terminal. Without this, highly reliable data transmission with the mobile terminal can be performed, and the equipment installation cost can be reduced.

In FIG. 1, between the mobile phone 2 and the mobile communication modem 5 connected to the communication relay device 6, it is possible to perform error-free communication via the wireless line 3 and the public telephone line 4. , Communication using an error detection / correction method suitable for mobile communication is performed. The monitoring terminal communication modem 7 connected to the communication relay device 6 is for communicating with the monitoring terminal device 8 via the public telephone line 4, and is basically used in the monitoring center. The communication method is the same as that used.

The operation procedure of the present invention in the above equipment configuration will be described with reference to the block diagram of FIG.

The communication relay device 6 monitors the output of the mobile communication modem 5 and receives an incoming call from the portable terminal device. (Procedure S
1) When a maintenance person operates the mobile terminal device 1 and makes a communication request to the monitoring terminal device 8, the mobile terminal device 1 sends a message to the mobile phone 2.
Mobile communication modem 5 connected to the communication relay device 6
Dial the line number of. The communication relay device 6 requests the mobile phone 2 to shift from the call mode to the data communication mode after the mobile communication modem 5 receives the call.
After the mobile terminal device 2 shifts to the data communication mode, the communication relay device 6 receives the communication request data for the specific site from the mobile terminal device 1. (Procedure S2) After receiving the communication request data from the mobile terminal device 1, the communication relay device 6 confirms that the communication request data is valid, and then disconnects the line of the mobile phone. Here, the communication request data is code information for specifying the monitoring terminal device 8, the type of data to be collected, control data, and the like,
Since the amount of data is relatively small, the communication of the communication request data ends in a short time. (Procedure S3) The communication relay device 6 communicates with the monitoring terminal device 8 specified through the communication request data received in step S2 via the monitoring terminal communication modem 7 and the public telephone line 4. Then, the data of the type specified in the communication request data is collected, the control data is transmitted, and the control result is confirmed. The data (collected data, control result, etc.) obtained as a result of the communication is stored in the storage device 9 connected to the communication relay device 6. (Procedure S4) After the communication with the monitoring terminal device 8 is completed, the communication relay device 6 performs preprocessing of the communication data stored in the storage device 9 such as compression so as to be suitable for communication. If the data is the same type of repetition, the amount of data to be communicated can be greatly reduced by performing compression. (Procedure S5) After the preprocessing of the communication data is completed, the communication relay device 6
The mobile phone 2 that has received the communication request in step S2 is called via the monitoring terminal communication modem 7. (Procedure S6) When the mobile terminal 1 detects that the mobile phone 2 has arrived in the data communication mode, communication is started, and the data subjected to the preprocessing in step S5 is received from the communication relay device 8. (Procedure S7) When the mobile terminal 1 completes the data reception, the communication relay device 6 disconnects the line of the mobile phone and returns to the incoming call waiting state from the mobile phone. (Procedure S8) By performing the above procedure, the maintenance staff can collect necessary data with the mobile terminal device through the mobile phone in the minimum required communication time.

In step S2, it is possible to instruct a plurality of terminals to collect and control data. In this case, in step S4, it is possible to use the plurality of monitoring terminal communication modems 7 to perform the work of dealing with a plurality of sites. For example, this function is useful for elevators that are located in areas that may be flooded due to typhoons.
When remote control is performed with instructions of times, the elevator is moved to a floor above the ground and is on standby, or when an earthquake occurs, the elevator seismometer operates in a wide range, or there is a power outage, This is effective when the maintenance personnel use this function to collectively grasp the status of the building that he / she is in charge of and determine the patrol order.

Further, in the present invention, in step S4,
Since the data collected from the monitoring terminal device 8 is stored in the storage device 9, for example, even when the communication with the corresponding portable terminal device cannot be executed in step S6, the maintenance staff operates the portable terminal device 1. , By instructing to read the data, the communication relay device 8 determines that the communication is for data reading in the post-call procedure S2, and the collected data related to the designated building is read from the storage device 9 and stored in the mobile terminal device. By transmitting, it becomes possible to transmit the collected data and the control result more reliably.

As an example of applying the device configuration of the present invention,
As shown in FIG. 2, it is possible to install the communication relay device in units of managing elevators and building equipment. For example, this format can be applied to the case of collectively monitoring a plurality of apartment houses or building facilities connected by the local line 201 or the like. By taking this installation formation, 1
By communicating once, it is possible to collect the operating status and abnormal status of all connected elevators and building equipment, and it is possible to significantly reduce the communication time.

Further, as shown in FIG. 3, instead of using the mobile communication modem 5 when installing the communication relay device in the above-mentioned housing complex or building equipment, a mobile phone 10 having an equivalent function is used for communication relay. Direct connection to the device enables direct wireless communication between the communication relay device and the mobile terminal device. The advantage of this connection method is that even when the public telephone line 4 becomes difficult to use due to various disasters, it becomes possible to collect the operating status and abnormal occurrence status of the elevator and building equipment via wireless communication, and by extension, , It is possible to quickly grasp the situation and take countermeasures for elevators and building equipment.
