Abstract

PURPOSE:To make a slave station side know the measured value and its kind and to monitor the operational state of a device being monitored by making a master station send a display setting data so as to initialize the slave station so that the slave station may display the various measured values collected by the slave station whose content is identical with that of the master station. CONSTITUTION:In a master station 1, a display setting data generating part 3 sends and registers a display setting data 4 far displaying the actual operational value at respective measuring points of the device being monitored on a display device 11 in a display setting area 5 of a slave station 2. A measured value collecting part 6 of the slave station 2 collects various measured values from the device being monitored and a display data generating part 7 makes them correspond to the display setting data registered in the display setting area 5 and converts and generates the various measured values collected by the measured value collecting part into a display data and then accumulates them in a display data information storing part 8. The display data information storing part 8 displays the display data information on the display part 11 of the slave station 2, and later, sends and displays a display data information 10 on a display part 11 of the master station in response to a display data information request 9 from the master station.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote monitoring system in a remote monitoring system composed of a master station and a plurality of slave stations, and more particularly to displaying measurement data of the slave stations.

[0002]

2. Description of the Related Art In a conventional distant monitoring system, an analog signal measured from a monitored device is compressed and converted into a predetermined transmission signal, for example, and transmitted from a slave station to a master station. In addition to converting to, the unit of the data was added and displayed corresponding to the test item. At this time, the slave station simply displayed the compressed and converted measurement data as it was, and did not know which test item the display data corresponded to and the true value and unit of the data.

[0003]

In the conventional remote monitoring method, the measured value of the analog input from the monitored device is converted into display data at the master station and displayed, and the measured value is displayed at the slave station as it is. Therefore, it is difficult for the slave station side to determine what data represents what from the displayed contents, and thus it is difficult to confirm whether the monitored device is operating normally.

It is an object of the present invention to provide a remote monitoring system capable of displaying true data corresponding to the same test item as the master station on the slave station side.

[0005]

According to the remote monitoring method of the present invention, a plurality of slave stations for individually monitoring the actual operation of an arbitrary plurality of locations of a monitored device and collecting the measured values are transmitted through a transmission path. Display setting data for displaying various data required by the master station as actual operation values at each measurement point of the monitored device in a distant monitoring system that is housed in the master station and manages the operating state of the monitored device Is registered in the slave station, the slave station converts and collects each collected measurement value of the monitored device into an actual operation value at each measurement point corresponding to the display setting data, and stores the same. The actual operation value of each measurement point displayed on the display device and stored in response to the request from the master station is transmitted.

[0006]

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, in which a monitoring item for monitoring a monitored device (not shown) and a true value and a unit of its measured value (analog input) are designated. Areas corresponding to the master station 1 including the display setting data creation unit 3 and the display unit 11 that displays the monitoring data converted into the true data of the measurement points corresponding to the monitoring items, and the display setting data from the master station 1. The display setting area 5 for analog input stored in the table and the measurement value collection unit 6 that stores the analog measurement values from the monitored device corresponding to the monitoring item and various measurement values from the measurement value collection unit 6 to create true display data A display data creation unit 7 and a display data information storage unit 8 that stores the created display data and sends the accumulated data in response to a display data information request from the master station 1 and a display unit 1 that displays the same display data as the master station. Configuring from the slave station 2 which made of.

The master station 1 sends the display setting data from the display setting data creating section 3 to the slave station 2. Upon receiving the display setting data 4, the slave station 2 writes the data in the display setting area 5. The display data creation unit 7 recreates the display data corresponding to the data in the display setting area for each measurement value from the measurement value collection unit 6, and stores it in the display data information storage unit 8. The display data of the display data information storage unit 8 is displayed on the display unit 11 of the slave station. After that, when the display data request signal 9 is received from the master station 1, the slave station 2 receives the display data information storage unit 8
To send corresponding display data to the master station 1. In the master station 1, the display data is displayed on the display data display unit 11.

[0009]

As described above, according to the present invention, by transmitting display setting data from the master station and initializing each slave station, various measurement values collected by each slave station from each monitored device can be obtained. Since the same content as that of the master station can be displayed on the slave station, the slave station can know what data the measured value represents and can monitor the operating state of the monitored device.
