  Conventionally, monitoring control systems have been introduced in buildings and the like. Such a monitoring control system includes a monitoring control device that monitors and controls load equipment such as lighting equipment installed in a proper place in a building, a communication terminal device such as a personal computer, a wide area network (WAN) or a private network ( It is configured by connecting via a communication network constituted by a LAN, and the load device can be remotely monitored and controlled by giving an instruction to the monitoring control device from the communication terminal device.

  By the way, such load device state data is stored as a plurality of contents in the monitoring control device, and the monitoring control device corresponds to the load device state when receiving the transmission request data from the communication terminal device. Select and send status data

However, such status data is uniformly transmitted regardless of data and signal congestion and the data processing capability of the communication terminal device. For this reason, communication terminal devices have diversified from high-performance and high-performance to portable terminals, and the number of components of communication networks has increased, so there is a limit to support with the same state data, for example, wide area network ( The state data created to be transmitted to a UNIX (registered trademark) compatible communication terminal device connected to a LAN) has a large capacity, so that data and signals transmitted and received through the communication network are crowded, or the communication terminal When the data processing capability of the device is low, it takes time to confirm the state of the load device on the communication terminal device side, resulting in a system with poor responsiveness.

  In order to solve this problem, for example, measures to recommend the components of the communication network and the functions of the communication terminal device to the user can be considered, but today, when open systems have become mainstream, this limitation is limited to the user. It would be a big disadvantage and not an essential solution. The present invention has been made in consideration of the above circumstances, and when the monitoring control device receives transmission request data from the communication terminal device via the communication network, the components of the communication network and the functions of the communication terminal device are provided. It is an object of the present invention to provide a monitoring control system capable of returning optimal monitoring control data according to the above and a program recording medium capable of causing the monitoring control apparatus to execute such a function.

  In order to achieve the above object, a monitoring control system of the present invention includes a monitoring control device that monitors and controls a load device such as a lighting device, and a communication terminal device connected to the monitoring control device via a communication network. In the supervisory control system configured in combination, the supervisory control device receives the transmission request data requesting transmission of the supervisory control data of the load device from the communication terminal device via the communication network. The configuration is such that monitoring control data having different capacities can be selectively transmitted to the communication terminal device in accordance with the time at which the transmission request data is received, and the transmission request data is transmitted at a time within a predetermined time zone set in advance. The amount of monitoring control data to be transmitted when received is set to the monitoring control data to be transmitted when transmission request data is received at a time other than the predetermined time zone. Characterized by smaller than the capacity of the data.

In such a monitoring control system, the monitoring control device further selectively selects monitoring control data having a larger capacity as the data transfer speed in the communication network to which the transmission request data is transmitted from the communication terminal device is higher. It is good also as a structure which can transmit.
At this time, when the monitoring control device receives transmission request data at a data transfer rate slower than a predetermined rate via the communication network at a time within the predetermined time zone, the first monitoring control data When the transmission request data is received at a data transfer rate faster than a predetermined rate via the communication network at a time within the predetermined time zone, the data capacity is larger than that of the first monitoring control data. When the second monitoring control data is transmitted and the transmission request data is received at a data transfer speed slower than the predetermined speed via the communication network at a time other than the predetermined time period, the third monitoring control data is received. When transmitting data and receiving transmission request data at a data transfer rate faster than a predetermined rate via the communication network at a time other than the predetermined time zone, Transmits the serial data capacity than the third monitoring control data is large fourth monitoring control data, the first to among the fourth monitoring control data, the data capacity of the first monitoring control data is the smallest, the fourth monitoring control It is assumed that the data capacity of data is the largest.

The monitoring control system according to the present invention includes a monitoring control device configured to combine a monitoring control device that monitors and controls a load device such as a lighting device, and a communication terminal device connected to the monitoring control device via a communication network. In the system, when the monitoring control device receives transmission request data requesting transmission of monitoring control data of the load device from the communication terminal device via the communication network, The higher the data transfer speed in the communication network, the higher the capacity of the monitoring control data can be selectively transmitted, and the capacity of the monitoring control data may be varied according to the monitoring control status of the load device. .

  According to the present invention, when receiving the transmission request data for requesting transmission of the monitoring control data of the load device from the communication terminal device via the communication network, the monitoring control device receives data and signals transmitted and received through the communication network. The optimal monitoring control data can be transmitted according to the congestion, data processing capability of the communication terminal device, etc., and the communication terminal device side can quickly check the state of the load device, and the responsiveness can be improved. Can be improved.

  The monitoring control device receives the transmission request data from the communication terminal device to the communication terminal device when receiving transmission request data requesting transmission of the monitoring control data of the load device via the communication network. Since different types of monitoring control data are selectively transmitted according to the time, for example, in the early morning, when there are many requests from the communication terminal device, data with a small capacity is transmitted, while when there are few requests, If data having a small capacity is transmitted, good responsiveness can be ensured.

  When the monitoring control device receives transmission request data for requesting transmission of the monitoring control data of the load device from the communication terminal device via the communication network, the monitoring control status of the load device is transmitted to the communication terminal device. Accordingly, different types of monitoring control data are selectively transmitted, for example, when the control unit of the monitoring control device performs monitoring control of the load device, the load device transmits data having a small capacity. When the monitoring control is not performed, good responsiveness can be ensured by transmitting a large amount of data.
