Abstract

PURPOSE:To shorten time for a system operation by making the condition of each terminal equipment constant, detecting the condition by means of a communication with a central supervisory equipment, obtaining the logical address of the terminal equipment, and making the logical address correspond to a number on the screen of each terminal equipment in the constant condition. CONSTITUTION:A monitoring device M1 allocates the address to each sensor, and allocates logical addresses 4, 5, 6, 1, 2 and 3 to sensors 200 to 205. On the other hand, since the correspondence among sensors 100 to 105 displayed on the screen, the logical address allocated by the automatic address, and the sensor numbers on the screen is unknown, the condition of each terminal equipment 100 to 105 is made constant, the logical address in such a condition is detected by the communication, and the logical address is made to correspond to the terminal equipment on the screen. Thus, the address-allocated equipment is automatically made to correspond to contents on the screen.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for creating a monitoring screen for a monitoring system, control system, etc.

[Prior art]

In various monitoring and control systems, the status of objects to be monitored, etc. is displayed on a monitoring screen such as a CRT. In some cases, the location and name of the monitored points are displayed on the screen so that the contents of the monitored point can be understood, but recently the entire system is displayed visually in the form of figures or floor plans, making it easier for operators to understand. It's starting to look like this.

In order to display such a display, it is necessary to: ■ create a monitoring screen, etc., ■ assign an address to each monitoring point so that the computer can monitor and control it, and the content on the screen and its address. It is necessary to make a correspondence between the two. Traditionally, ■ monitoring screens etc. were created in factories, etc., and ■ and ■
The assignment of addresses and the correspondence with the screen were done on-site, but the address assignment had to be done based on the settings of the depth inch of the equipment installed on-site, and this adjustment work took a considerable amount of time. It takes.

[Problems] In recent technological developments, automatic address setting has been proposed from the perspective of saving labor in address setting. For example, there is Japanese Patent Application No. 63-32906.

However, even if only the address setting is saved, a large amount of time and effort remains in associating the address with the device on the created screen, so the overall work required to operate the system becomes large.

[Object of the Invention] The present invention has been made in view of the above points, and provides an apparatus and method for automatically associating devices to which addresses are assigned and contents on a screen.

(Means) According to the method of the present invention, a plurality of terminal devices having a first address and a second address set separately from the first address, and a transmission path common to the plurality of terminal devices are provided. It consists of a connected central monitoring device, and the central monitoring device communicates with each terminal device using a second address set based on the first address, and updates the status of each terminal device according to information from each terminal device. In a status monitoring system that displays on a status display screen, each terminal is set to a certain state, the central monitoring device detects the state through communication, obtains the logical address of the detected terminal, and displays the obtained logical address and the fixed state. The purpose is to achieve the above objective by associating the numbers on the screen of each terminal device.

According to the device of the present invention, each terminal device includes a storage means for storing a first address and a second address set separately from the first address, and a communication means for communicating with the central monitoring device. The central monitoring device has a status display screen that stores the number and display position of each terminal to be displayed and displays the status of each terminal, and a second address of each terminal. A storage means for storing information, a communication means for communicating with each terminal device, and communication based on a second address of each terminal device stored in the storage means to determine whether each terminal device is in a constant state. and a storage means that stores the second address of the terminal in correspondence with the number of the terminal on the screen when the state detection means detects a certain state. It accomplishes its purpose.

The present invention will be explained below using examples.

〔Example〕

FIG. 1 shows a plan view of a building displayed on a CRT.
are sensors for various terminal devices, all of which are disaster prevention sensors. In this embodiment, a disaster prevention sensor is used, but it may also be a security, temperature, humidity, etc. sensor, and the terminal device is not limited to a sensor, but may be a computer or the like having communication means. Many types of screens of this kind are prepared in the control/monitoring system, and the operator performs various operations and monitors while looking at these display screens. This plan view on the screen and the status of the monitoring point represented therein, ie, how the analog or digital values of the sensors change, are displayed on the screen. For example, when a detected value exceeds a set value or a fire is detected, the display of these sensors changes color, flashes, and more specifically displays the measured value to inform the operator of the status of the monitoring point. It shows that.

FIG. 2 shows this monitoring system, in which each sensor 200.201, 202.203.204.205 is connected to the disaster prevention monitoring device Ml via a communication line L2. Similarly, other terminals are also connected to the disaster prevention monitoring device M2 via another communication line L3. These monitoring devices Ml
and M2 are further connected via a higher level communication line L1 and can communicate with each other.

In such a system, by using the automatic addressing described above, the monitoring device M1 allocates addresses to various sensors, and
Logical addresses (4) and (
Suppose that 5), (6), (1), (2), and (3) are correctly applied.

The monitoring device M2 similarly allocates logical addresses to the sensors connected on the communication line 3. The following description will be made regarding the sensor on the communication line Ll.

Each sensor has not only communication means but also memory means,
As shown in Table 1 below, the above logical address values are stored in the memory in correspondence with each sensor.

Table 1 Meanwhile, 100.101.102.10 displayed on the screen
The sensors 3.104.105 are located at the positions shown in Fig. 1 on the plan view, but the logical addresses stored in the monitoring device M1 and each sensor that are assigned by automatic addresses and the sensor numbers on the screen are as follows. It is unclear which corresponds to which.

Therefore, according to the present invention, each terminal is placed in a certain state, the logical address in that state is detected through communication, and the logical address is associated with the terminal on the screen.

For example, there are two methods.

The first method, as shown in Figure 3, is to provide a disconnection switch SW for each sensor, operate the switch to maintain a certain state, call each sensor using a logical address assigned by automatic addressing, and respond. Since the sensor without is the currently disconnected sensor, this method associates the sensor on the screen with the logical address.

This will be explained in more detail below.

First, an operator who monitors the screen shown in Figure 1 and a worker who operates the disconnect switch for each sensor in the actual building are placed.The operator and the worker communicate with each other via transceiver, telephone, etc. The sensor that operates the sensor is associated with the display on the screen.

Suppose that a worker operates a disconnect switch for a sensor in a building that corresponds to the screen. The operator is informed of the position of the sensor along with the operation. Since the control/monitoring device can communicate with each sensor using logical addresses, it constantly monitors whether each sensor is normal or whether any response is returned from each sensor. When any disconnection switch is operated, the logical address of the non-responsive sensor is displayed on the screen by the process shown in FIG. Each sensor is polled based on its logical address,
It detects whether there is a response or not, and if there is no response, the logical address is displayed on the screen and the operator is notified. Since the operator communicates with the worker using a transceiver, he can associate the display position of the sensor on the screen with the displayed logical address, and can set the logical address corresponding to the sensor's on-screen number. Store in memory. By performing this work for each sensor, the sensor number on the screen and the logical address are associated with each other. For example, as shown in Table 2, numbers on the screen are associated with logical addresses.

Table 2 Next, the second method will be explained.

In the first method, the sensor is provided with a special switch, but there is no need to take the trouble to provide this type of switch. For example, when a crime prevention sensor or a disaster prevention sensor is actually operated as an operation test, if the worker informs the operator of which position of the sensor is being tested, logical addresses can be associated in the same way as above. can be done. This method can also be applied to various sensors such as temperature and humidity. That is, as shown in FIG. 5, it is sufficient to detect whether or not there is a detection output, and if there is, to display the logical address on the screen.

This method is economical in that it can also be used as an operation test.

Still another method is for an operator to use a sheet of paper with a plan view as shown in Fig. 6 and a porta-pull setting device PST connected to each sensor, and assign a logical address to each sensor D as shown in Fig. 7. another identification code, e.g. a consecutive number (1),
Write [2], [3], [4], (5), and [6] into the memory within the sensor.

Based on the paper, data as shown in Table 3, for example, is stored in the memory in the monitoring device so that the sensor number on the operator's monitoring screen corresponds to its identification code.

Table 3 [Effects] As described above, according to the present invention, after automatic addressing, the terminal device on the monitoring screen and its assigned address can be easily correlated, and as a result, system operation can be improved. This is extremely effective as it reduces the amount of time required to do so.
