  In this type of monitoring system, a monitoring terminal 51 as shown in FIG. 5 has been conventionally used. The monitoring terminal 51 includes a monitoring process execution unit 52 that processes monitoring data received from a monitoring device (not shown), a screen display unit 53 that displays data processed by the monitoring process execution unit 52 on a screen, and a monitoring device. And a monitoring setting holding unit 54 for setting and holding registration information such as a display address and a display position on the screen. Then, common monitoring software is installed in each of the plurality of monitoring terminals 51, and the monitoring processing execution unit 52 accesses the monitoring device using the registration information set in the monitoring setting holding unit 54. .

  Here, registration information such as the address and display position of the monitoring device has been conventionally set for each monitoring terminal 51. For this reason, when registering a new monitoring device or removing a monitoring device that is no longer needed, the setting contents of the monitoring setting holding unit 54 are changed at each monitoring terminal 51 to monitor the monitoring software. It was necessary to unify registration information. In changing the setting, conventionally, as shown in FIG. 6, a setting change screen is displayed on the screen display unit 53 of each monitoring terminal 51 (S61), and the contents of the setting change are input by operating the keyboard or the like (S62). ) After storing the change contents in the monitoring setting holding unit 54 (S63), the change is notified to the monitoring process execution unit 52 (S64).

  However, according to the conventional monitoring system, when the registration information is changed, it is necessary to change the setting in all the monitoring terminals 51. Therefore, if the number of the monitoring terminals 51 is increased, the change work takes time, or the change work is performed. There was a problem such as a device that was forgotten to appear. Moreover, since each monitoring terminal 51 can change registration information independently, there is a possibility that an incorrect address is registered in some monitoring terminals 51 or a necessary address is not registered. It was difficult to accurately match the registration information of the monitoring terminal 51 with the same content.

  An object of the present invention is to solve the above-described problems and provide a monitoring system that can easily and accurately update registration information set in the monitoring software in a system in which a plurality of monitoring terminals use common monitoring software. There is.

  In order to solve the above-described problems, a monitoring system according to the present invention connects a plurality of monitoring terminals via a network to a plurality of monitoring devices that acquire operation information of electrical equipment, and each monitoring terminal has a common monitoring software. In the system that accesses the monitoring device using the registration information set in, the monitoring terminal is composed of a master monitoring terminal and a slave monitoring terminal, and the registration information of the monitoring software is held in the master monitoring terminal in a changeable manner Means and means for transmitting the changed registration information to the slave monitoring terminal.

  Here, as the monitoring device, for example, a device for monitoring the environment of the farm, a device for monitoring the environment or electric lock in the LAN rack installed in the server room or the data center, a device for monitoring equipment of supermarkets or convenience stores Etc. Examples of electrical devices that are monitored by the monitoring device include temperature sensors, humidity sensors, CO2 sensors, pH sensors, water level meters, noise sensors, power / voltage / current sensors, and the like. As the monitoring terminal, a device that can communicate with the monitoring device via a network, such as a personal computer, a mobile phone, or a PDA, can be used.

  In the monitoring system of the present invention, when a new monitoring device is registered in the monitoring terminal or when a monitoring device that is no longer needed is removed from the registration, the registration information is changed on the master monitoring terminal. Registration information is transmitted from the master monitoring terminal to the slave monitoring terminal. For this reason, in the slave monitoring terminal, it is not necessary to perform a troublesome input work, and there is no possibility of forgetting the change work, and the registration information of all the monitoring terminals can be updated in a short time and easily. In addition, since the setting change work is performed centrally by the master monitoring terminal, it is easy to accurately match the registration information of all the monitoring terminals with the same contents.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the monitoring system of this embodiment is installed or carried around a plurality of monitoring devices 1 installed around various electric devices (not shown) and at a remote location away from the monitoring device 1. A plurality of monitoring terminals 2 and 3 are provided. Each monitoring device 1 is connected to various sensors provided in the electric device, and monitors the operation state (operation status) of the electric device based on operation information and environmental information acquired from the sensor. Each of the monitoring terminals 2 and 3 is connected to the monitoring device 1 via the network such as the Internet 4 or a LAN, and monitors the operation state of the electrical device based on the data received from the monitoring device 1.

  The monitoring terminals 2 and 3 are composed of one master monitoring terminal 2 and a plurality of slave monitoring terminals 3, and common monitoring software is installed in each. As shown in FIG. 2, the master monitoring terminal 2 includes a monitoring process execution unit 5 that processes the monitoring data received from the monitoring device 1, and a screen display unit 6 that displays the data processed by the monitoring process execution unit 5 on the screen. The monitoring setting holding unit 7 that holds (stores) registration information such as the address of the monitoring device 1 and the display position on the screen in a changeable manner, and the registration information of the monitoring setting holding unit 7 is transmitted to the slave monitoring terminal 3 and And a monitoring setting transmission / reception unit 8 for receiving a response message from the slave monitoring terminal 3.

  The slave monitoring terminal 3 includes a monitoring processing execution unit 52, a screen display unit 53, and a monitoring setting holding unit 54 as in the conventional case (see FIG. 5). And registration information such as display position is kept unchangeable. Then, when changing the registration information set in the monitoring software, the master monitoring terminal 2 changes the setting contents of the registration information, stores the changed registration information in the monitoring setting holding unit 7, and sets the monitoring setting. The information is transmitted from the transmission / reception unit 8 to the slave monitoring terminal 3, and the slave monitoring terminal 3 receives the changed registration information and stores it in the monitoring setting holding unit 54.

  FIG. 3 shows registration information changing processing by the master monitoring terminal 2. First, the master monitoring terminal 2 checks whether there is a change in the setting contents of the registration information (S21). When there is a change in the registration information, the registration information file in the monitoring setting holding unit 7 is updated (S22), and the updated registration information file is transmitted from the monitoring setting transmission / reception unit 8 to the slave monitoring terminal 3 (S23). Based on the response message of the slave monitoring terminal 3, it is confirmed that the updated file has been transmitted to all the slave monitoring terminals 3 (S24), and the registration information changing process is completed.

  FIG. 4 shows registration information changing processing by the slave monitoring terminal 3. The slave monitoring terminal 3 always sets the reception standby mode (S31), and confirms reception from the master monitoring terminal 2 (S32). Then, when the master monitoring terminal 3 transmits the updated registration information file, the slave monitoring terminal 3 receives this file (S33) and stores it in the monitoring setting holding unit 54 of the own device (S34). After that, the slave monitoring terminal 3 accesses the required monitoring device 1 using the screen information and address information registered in the updated file, and monitors the operating state of the electrical equipment managed by the monitoring device 1.

  Therefore, according to the monitoring system of this embodiment, when registering a new monitoring device 1 or removing a monitoring device 1 that is no longer necessary, registration information is changed on the master monitoring terminal 2, The changed registration information can be transmitted from the master monitoring terminal 2 to all the slave monitoring terminals 3 all at once. Accordingly, it is possible to complete the updating operation of the monitoring software easily and in a short time by omitting the input operation at the many slave monitoring terminals 3. In addition, since the master monitoring terminal 2 performs the setting change work in a centralized manner, it is possible to accurately match the registration information of all the terminals with the same contents, and in particular, a large-scale system with a large number of monitoring terminals 2 and 3 There is an advantage that confusion associated with the setting change can be avoided.
