[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring control system for remotely monitoring equipment such as an electric lock and various sensors as a terminal device, and more particularly to a start control of a terminal device.

[0002]

2. Description of the Related Art FIG. 3 is a block diagram showing a conventional remote monitoring control system for starting and controlling a terminal device. In FIG. 3, 1 is a host CPU, 2 is a main controller for accumulating terminal setting data and centrally managing a plurality of local controllers to be described later, and a communication control unit 21 for communicating with the host CPU 1; A transmission control unit 22 for transmission with the controller, and an input / output unit 23
And a terminal setting data storage unit 25 for storing terminal setting data. The host CPU 1 is connected to the host CPU 1 via a communication line 5.

[0003] Reference numeral 3 denotes a local controller for storing terminal setting data, controlling a terminal device to be described later, transmitting a terminal operation state to a higher-order side, and the like, and a transmission controller for performing transmission with the main controller 2. 31 and input / output unit 3
2, a CPU 33, a terminal setting data storage unit 34 for storing terminal setting data, and a terminal interface 3 that performs an interface function with a terminal device described later.
5 and is connected to the main controller 2 by a transmission line 6. Reference numeral 4 denotes a terminal device indicating equipment such as an electric lock and a security sensor, which are connected to the local controller 3 via a transmission line 7, respectively.

Next, the operation of the remote monitoring control system according to the above configuration will be described with reference to the operation flow shown in FIG.
First, when the system is started, the host CPU 1 downloads the terminal setting data of the terminal device 4 to the main controller 2 when the terminal setting data in the host CPU 1 does not match the terminal setting data in the main controller 2 (step S1). S41 to S43). Here, the terminal setting data defines an operation after the terminal device is started, and does not define a state at the time of starting the terminal device 4. When the download of the terminal setting data of the terminal device 4 from the host CPU 1 is completed, the main controller 2 downloads the data to the local controller 3 (step S44). The local controller 3 starts the terminal device 4 in a default state (significant side) predetermined in the system based on the downloaded data (step S45). This means that the terminal device is activated in a locked state when the terminal device is an electric lock and in a guarded state when the terminal device is a sensor.

After the system is started, remote control from the host CPU 1, status control based on a schedule, and terminal device 4
The terminal state changes due to the direct operation or the like, and the state change is always displayed by the host CPU 1. At the same time, the host CPU 1 constantly monitors the coincidence state between the terminal setting data in its own device and the terminal setting data in the main controller 2.
Only when the forced download instruction is issued in PU1, the terminal setting data is downloaded to the main controller 2 again (steps S41 → S42 → S46).
→ S43). The main controller 2 is a host CPU 1
When the data is downloaded again or when the local controller 3 is reset, the data is downloaded to the local controller 3, and the local controller 3 sets the terminal device 4 irrespective of the previous operation state (significant side or insignificant side). , Restart in the default state (significant side) (steps S43, S47 → S44 → S4)
5).

[0006]

As described above, the start control of the terminal device 4 in the conventional remote monitoring and control system is performed by setting various terminal setting data in the terminal device 4 and then setting the terminal device 4 in advance in the system. Because the system was already running because the terminal was started in the determined default state and the terminal device was started and operated in various states, it started up in a predetermined state. Terminal state is ignored. For example, when the terminal setting data is downloaded to the local controller 3, the previous operation state is the insignificant side (the unlocking state of the electric lock,
The terminal device 4 which was in the security state of the sensor) will be in a state different from the previous operation after restarting the system, and if it is an electric lock, the user will be locked in the room, and If so, an alarm that should not be generated is generated. As a result, there is a problem that the user of the terminal device 4 is adversely affected, and a task such as returning the state of the terminal device 4 to the system administrator also occurs.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems of the related art, and it is intended to perform start-up control without any problem when starting up a terminal device, even if the current state of the terminal device is unknown. The purpose is to obtain a remote monitoring and control system that can perform
