Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a supervisory control system that monitors and controls the operating functions of a communication device, and particularly to a main supervisory control device that monitors and controls the operation of the entire communication device system. The present invention relates to a supervisory control system that maintains a master-slave relationship between a communication system and a slave supervisory control device that monitors and controls various communication devices, and monitors and controls the entire communication system.

[Conventional technology]

In this type of supervisory control system, the main supervisory control device is generally placed in an operation control room that centrally manages and operates the communication system, and controls and monitors each communication device. On the other hand, the slave monitoring control device is placed in a communication room or the like, and monitors the operational functions of each device. And the slave supervisory control device is
It has the function of distributing control information addressed to multiple devices from the main supervisory control device to designated devices, and the function of periodically collecting supervisory control information indicating the operating status of each device and transferring it to the main supervisory control device.

As a conventional monitoring and control system, as shown in Fig. 7,
2. Description of the Related Art Supervisory control systems that monitor and control satellite communication devices are known. Hereinafter, a conventional supervisory control system will be explained with reference to FIG.

The main supervisory control system 100 includes a main supervisory control device 101,
It consists of an operator console 102 and a printer 103. The main supervisory control system 100 is further provided with a storage device (not shown) such as a floppy disk device or a hard disk device, if necessary. In particular, the operator console 102 includes a satellite communication system 1
The configuration and operational status of each subsystem in 10 is displayed graphically. Additionally, there is a function that allows the operation mode of each device to be controlled by operating a batch pad control area installed on the CRT of the console. The printer 103 prints out log data obtained by real-time data logging processing, which is one of the functions of the main monitoring and control device 101. The log data includes failure information for each device and new operation mode information accompanying changes in the operation mode.

Next, the satellite communication system 110 will be explained. The satellite communication system 110 is comprised of various communication devices that manage satellite communication. Various communication devices are grouped according to function and constitute subsystems. The satellite communication system 110 operates in a high frequency band (generally 4 GHz to 30 GHz).
frequency division multiple access (FDMA)
The TXGCE subsystem 11 consists of communication equipment based on the time division multiple access (TDMA) method and the 5CPC method.
3, an RXGCE subsystem 11114, a slave monitoring control device 112, and the like.

Next, the configuration and functions of the slave supervisory control device 112 will be explained. The slave supervisory control device 112 has a plurality of serial communication interfaces for communicating information with the main supervisory control device 101 and each subsystem, and a parallel input/output interface for monitoring and controlling various devices using a plurality of signal lines.

The functions of the serial communication interface are defined by the communication specifications of the communication interface in each subsystem and the communication specifications of the measuring instrument installed together with the communication device in the subsystem. These communication specifications include:
High-level data link control procedure (HDLC), general-purpose interface bus (GP-I) used in measuring instruments
B), synchronous/asynchronous according to R5-232C, etc.

Therefore, the communication interface of the slave supervisory control device 112 needs to have functions that match the respective communication specifications.

On the other hand, the parallel input/output interface is used to control and respond to the operations of the waveguide switch 122 and coaxial switch 120, which require real-time processing, and to transmit fault information of each device.

Next, a method for monitoring and controlling devices within each subsystem will be explained.

In FIG. 8, the main supervisory controller 10] is the slave supervisory controller 11.
2 shows a communication protocol for monitoring the operating status and controlling the operation of each device in the subsystem.

Between the communication interface monitoring and control (M&C) 15] of the main monitoring and control device 101 and the slave monitoring and control device 112,
Information communication is performed using the DLC protocol. The slave monitoring control device 112 and subsystems such as the weather observation device 111, the antenna control unit (ACU) 124, and the TXGCE subsystem 113 are connected to the R8-232C asynchronous and HDL
Data communication is performed using C communication specifications.

In addition, supervisory control functional elements that require real-time processing are associated with each interface of the parallel input/output interface 155, and can be used to control the interfaces individually or monitor all interfaces at once. do.

Control command information for each subsystem in the communication protocol on the M&C communication path 104 is specified by address space and yield A. 50 is a communication interface that interfaces the control command information received through the Tough Ace M&C 151 with the subsystem designated by the address field A. Transfer to.

Also, the communication interface specifications of the Zabu system are M&C.
If it is the same as the HDLC protocol of the communication path 104, the main CPU system 150 and each communication interface need only transparently transfer control command information.

But if the protocols are different, for example HDLC
In cases such as asynchronous communication with R5-232C, protocol conversion is required. This conversion is performed by the single chip CPU of each communication interface.

Further, control of the supervisory control functional elements by each interface of the parallel input/output interface 155 requires bit conversion for associating control information with each interface. This conversion is performed by the CPU of the main CPU system 150.
will do. Here, the supervisory control functional element refers to the monitored function,
This is a controlled function item.

On the other hand, the functional status of each subsystem is processed in the opposite way to the control command information, and is transferred to the main supervisory control device 101 as monitoring information.

2, from the slave supervisory control device 1 to the main supervisory control device 10
] The HDLC protocol information transferred to is divided into response information to command information and monitoring information.

The response information is a response indicating that the command information has been correctly received, and the monitoring information indicates the functional status of each communication device.

[Problem to be solved by the invention]

The operations and functions of the conventional supervisory control system have been outlined above.

Naturally, a monitoring and control system must have the ability to monitor and control the configuration, functions, and characteristics of various communication devices, but in order to achieve this,
It depends not only on hardware processing but also on software program processing. It is no exaggeration to say that this cannot be realized unless it is processed by a software program.

For example, in order to improve maintainability, the operator console 102 graphically displays the configuration and operational status of each subsystem 4 as a simulation, but this is all done by software program processing. . Also,
Monitoring and control information between each device and the supervisory control device is performed by software program processing.

As described above, as the dependence on software program processing increases, the scale of the software program also increases in proportion to the number, configuration, model, etc. of communication devices, and the complexity also increases. Under these circumstances, communication systems are becoming increasingly diverse due to the diversification of communication services and forms of communication.
The needs of our customers are also becoming more diverse.

Conventionally, in order to deal with these problems, new software programs for monitoring and control equipment have been developed that are suitable for each customer's communication system. However, the following problems have come to light with this approach.

1) Depending on the customer's communication system, software programs for master and slave monitoring and control equipment must be developed separately, or if software programs are developed for multiple customers in parallel, limited resources (time, people, software development support equipment) are required. ) cannot be processed.

2) The program processing functions of the main and slave monitoring and control devices are clarified in the software specifications, but when they are run during evaluation tests or before operation, they do not work properly due to software bugs, etc. It takes a lot of time to extract.

3) If each subsystem is made by the same manufacturer, the slave monitoring and control device can be monitored and controlled using a serial communication interface, but if subsystems made by other manufacturers are mixed, even if they have serial communication interfaces, the communication Since the protocols may be different, it is necessary to match (convert) the communication protocols.

In addition, if there is no serial communication interface, it is necessary to perform matching with a parallel input/output interface via a dry contact relay or the like.

Therefore, it is necessary to develop and design a software program for the slave monitoring and control device each time depending on the communication interface.

4) Parallel input/output interfaces are used depending on the functions and characteristics of each device, but since the number of interfaces is traded off with the price of the supervisory control device, their quantity is limited.

Therefore, when controlling and monitoring each device using a limited number of interfaces, it is necessary to fixedly assign specific supervisory control functional elements (for example, waveguide switch control) and input/output interfaces. It is not possible to attach the number, and it is necessary to allocate it on a case-by-case basis depending on the configuration and function of the customer's communication system. This allows HDL
Correlation between the control information and monitoring information of the C protocol and the parallel input/output interface must be performed by software program processing, and a software program must be developed each time.

Furthermore, when changing or expanding the communication system, software programs must be redeveloped.

If the above-mentioned problems are not resolved and dealt with using conventional methods, delivery dates will be delayed. Furthermore, it is obvious that reliability and quality will deteriorate significantly.

The comparison information is processed and created by the comparison information creation task at the request of the slave supervisory control device 20. In this task process,
Since the configuration and operational status of the communication equipment of each subsystem are displayed in a simulated manner on the color graphic CRT 2, the configuration information used in this display, as well as the bit array information of the information in the items and communication protocols of each monitoring and control function element, can be used as a basis. Comparison information is created.

This makes it possible to flexibly respond to configuration changes and expansion of communication devices.

That is, from the perspective of the CPU processor 50, it is treated as part of a peripheral device in the same way as the ROM 51.

In particular, supervisory control information is transferred to the communication interface boards via the CPU processor 50 and a mutually accessible common memory within each communication interface board.

The CPU system of each communication interface board includes:
The CPU processor used is such that the maximum effect can be obtained depending on the specifications of the communication protocol.

For example, if the communication protocol is asynchronous, a CPU processor with an asynchronous function is used, and if it is HDLC, a CPU processor with a DMA transfer function and HDLC functions is used.

The peripheral input/output interface 54 outputs a common memory request signal 61 for arbitrating mutual access to the common memory, and also inputs a common memory request response signal to recognize that access has been granted.

The parallel input/output input device (Ilo IN) 65 is for input six rings and consists of two blocks, an A block and a B block. A photocoupler parallel/output input section 63 is connected to the input terminals of these blocks. The interface of the plurality of parallel input/output input sections 63 is divided into two blocks, an A block and a B block.

- It is possible to recognize the state of P5 (physical on/off state).

On the other hand, parallel input/output output device (Ilo 0LIT)
66 is connected to a parallel input/output unit 64 consisting of a plurality of photocouplers.

Supervisory control functional elements are assigned to these parallel input/output input section 63 and parallel input/output section 64, respectively.

Next, the LED interface 56 and the LED display 23 will be explained.

The LED interface 56 connects to the CPU system bus 59.
It has a function to latch data transferred on the data bus, and has an LED driver.

In addition, the LED display 23 is NXM (in the embodiment, 4
It consists of a plurality of LED elements arranged in columns x 2 rows). Each LED element is color-coded into red, green, orange, and yellow, and each color represents the meaning of the supervisory control functional element.

Next, a method of displaying the status of a supervisory control functional element on an LED or LCD based on communication protocol conversion and supervisory control information using comparison information will be described with reference to FIGS. 4 and 5.

FIG. 4 shows the frame structure of the communication protocol on the M&C communication path 7. A frame consists of the following blocks:

The flag F is attached before and after the frame, and is used to synchronize the frame between transmitting and receiving.

Address field A is an address indicating the receiving device that receives the information. 00 iMEX) and FF LHE are assigned to each device, and only the receiving device specified by the address can receive the information.

Also, FF LIIEX) is called a global address, and the address field (A) is FF LHEX).
If so, all receiving devices can receive the information. This is information transfer in a so-called circular mode.

In FIG. 4, address 01. tHEx, ~06 (H
EX) It is allocated to each subsystem of the communication device.

Up to address 10 +oEx, ~OF IIEX),
It is allocated to the constituent devices inside the slave supervisory control device 20.

Control field C specifies the operation of the receiving device for commands, and for responses, it specifies responses to specifications.
Used to define communication rules.

The information field contains control information for control commands.
The same information as the control information for the control command is entered for the response, and monitoring information is entered for the monitor.

In this embodiment, the types of information are: 1) Control commands (control information) 2) Monitoring commands (requests for monitoring information) 3) Responses (responses to control commands) 4) Monitoring information (control commands for parallel input/output interfaces) and responses to monitoring commands).

The information is bit b. It is composed of array elements (1) to (n) consisting of 8 bits of -b7.

Array element (1) contains information on the information length indicating the number of array elements in the information section.

This is the second communication interface in FIG.
When the CPU system in the board 27 or the third communication interface board 28 transfers information to the subsystem,
Used to control the number of transfers.

Frame check sequence FC8 is for detecting information errors in parts A, 0, and 1 of the frame, excluding parts F and FC5.

Next, FIG. 5 will be explained.

FIG. 5 shows, as an example, the device function name Parallel I10. It shows the relationship between the physical addresses of LCD and LED and contrast information. In this table, Ilo is the parallel input/output input device 65 and parallel input/output output device 66 in FIG.

The physical address (H) is the parallel input/output input section 63.
Alternatively, it is an address for identifying each interface (signal line) of the parallel input/output output unit 64. In the table, the physical addresses are 001HEX) to IF LMEX)
This shows that it has up to 32 interfaces.

The comparison information is created by the comparison information creation task of the main supervisory control device 1, and is used to make the interface proposed by the physical address correspond to the array element in the communication protocol information and the supervisory control function element specified by the bit. belongs to.

Next, the parallel input/output input section 63 inputs the physical address 00.
The process of transferring the status of the supervisory control functional element a of the communication device connected to the interface specified by (HEX), that is, the supervisory information, to the main supervisory control device 1 is shown in FIGS.
This will be explained using FIG.

Prior to operation, the slave supervisory control device 20 obtains comparison information from the main supervisory control device 1 as shown in part e of the protocol sequence diagram of FIG. 6, and stores and retains it in the EE-PROM 53 of FIG. 3.

First, the transfer of monitoring information will be explained with reference to part f of FIG. 6.

The main CPU system 21 updates the status of the supervisory control functional elements connected to the interface of the parallel input/output input unit 63 at a fixed period (variable) to the parallel input/output input unit 65.
Get it through. Then, the main CPU system 21 is
As shown in part g of FIG. 6, the monitoring side vffJa! corresponding to the physical address 0OL) IP, The state of the supervisory control functional element a is assigned to the array element N08 (3) and bit NO, 1 indicated by the comparison information. The main CPU system 21 also records the status of the supervisory control function element in array element N.
o, (3) and bit No., 2 to create the information section of the supervisory control information. Therefore, even if there is no request for transfer of monitoring information by a monitoring command from the main monitoring and control device 1, the status of the monitoring and control functional elements is updated within the main CPU system 21.

Next, processing of control commands will be explained with reference to the sixth diagram.

When controlling the supervisory control functional element C, the main supervisory control device 1 first sets the address in the address field A of the communication protocol to 1 1 +)Ipx+, which is the address of the parallel input/output output device 66, and , (n-
2) and the information section assigned to bit No. 3 is transferred to the slave supervisory control device 20. The main CPU system 21 refers to the information section and the comparison information, recognizes that the supervisory control functional element C is at the physical address 00 fHEX) of the parallel input/output output section, and controls its input/output interface. The supervisory control functional element d is similarly controlled. That is, the supervisory control functional element d has a physical address of 0111EXl.
and controls the corresponding input/output interface.

Monitoring information for the control command is obtained a certain period of time after the input/output interface is controlled. This is because it takes into consideration that, for example, a waveguide switch requires zero time of about 500 msec for operation.

Next, a case will be described in which the status of the supervisory control functional element is displayed on the LED.

For example, the status of the supervisory control function element a is displayed as contrast information on the LED to which the supervisory control function element a is designated, that is, the LED at the physical address 00LHEXI. The contrast information consists of three blocks that allow display of not only parallel input/output interfaces, but also supervisory control functional elements of other subsystems.

The processing for the sound generator is the same as the processing for the LED.

Next, a case will be described in which the status of the supervisory control functional element is displayed on the LCD.

Basically, the display is the same as the display on the LED described above. However, since LCDs display character messages and numerical values, the contrast information includes information specifying a specific supervisory control functional element and a character message to be displayed when displaying the status of that supervisory control functional element on the LCD screen. and information indicating the display position.

For example, in Figure 5, the subsystem address is 10.
, the status of the supervisory control function element specified by array element No. 3, bit No. 2 is on the LCD screen No. 011, and is specified by message No. 4 from the position of line No. 2, row N015. A character message is displayed. The character message designated by the message number is stored in advance in the ROM 51 of the main CPU system 21 as fixed information. However, in addition to fixed information such as character messages, numerical information that changes in real time and fixed numerical information must also be displayed.

For this reason, the message number can be set to characters ≦7F and numerical values (
80-8F) ≧80, and 8F
The first digit of 0 to 8F, 0 to F, indicates the number of characters displayed numerically. For example, when the minus digit is displayed as 4 (84), the information for 4 numbers from the array element number 3 of the information section, number 0.2, is displayed as the LCD screen number.

It is displayed as a 4-digit number starting from line No. 2 and row No. 5.

Furthermore, the screen configuration information such as the title and supervisory control function name displayed on the LCD screen is downloaded in advance from the main supervisory control device 1 on a screen-by-screen basis and stored in the EE-FROM 5.
It is stored in 3.

The screen may be a single screen or multiple screens to display the status of the supervisory control functional elements of the subsystem.

By operating the keyboard 25, the maintenance person can freely select a screen and recognize the operating state of the communication device in real time.

The slave monitoring control device 20 has a plurality of communication interfaces and
The board is installed. Each communication interface
There are various boards based on communication protocol specifications, such as R8-232C asynchronous and HDLC.

Moreover, the mounting position of these components within the slave monitoring and control device 20 is not specified, and the mounting location can be freely determined depending on the configuration of the communication system. This uses the keyboard 25 and LCD 24 to display the slot number indicating the physical mounting position and the subsystem address (
The address shown in the address field A of the communication protocol) is associated, and the correspondence is established by setting a sub-allore address using a dip switch mounted in the communication interface φ board.

Note that the present invention is not limited to the above embodiments, and various modifications are possible. For example, each function of the slave supervisory control device may be provided within the main supervisory control device. In this case, the slave supervisory control device can eliminate the functions of the keyboard, LCD, LED, and sound generator, and concentrate on transmitting the supervisory control information. In addition, the supervisory control system is composed of a plurality of ten or less main supervisory controllers and a single slave supervisory controller, and the supervisory control information is transferred between each main supervisory controller and the slave supervisory controller at any time. You may also allow it to be done.

In this case, connection control of multiple main supervisory controllers (communications , disable control).

[Effects of the Invention] As explained above, the present invention creates comparison information that can be flexibly dealt with in accordance with the configuration form of communication devices in a communication system in a main supervisory control device, and downloads it to a slave supervisory control device. On the other hand, the slave supervisory control device has a means for
Each communication device is directly monitored and controlled, and at that time, the monitoring and control functional elements of the communication device are monitored and controlled based on comparison information downloaded in advance from the main monitoring and control device.1) The operational functions of the slave supervisory control device are performed based on the comparison information and are therefore less dependent on software programs. Therefore, it is possible to flexibly respond to the configuration of communication devices in the communication system.

2) Item 1) eliminates the need to develop a software program depending on the configuration of each communication device.

3) As a side effect of item 2), (1) Delivery dates can be secured.

(2) Productivity improves.

(3) Since existing needle software programs can be used, the reliability of the system is improved.

4) The various functions of the main supervisory control device can be easily constructed into an integrated supervisory control device that is incorporated into the slave supervisory control device.

5) A system for monitoring and controlling slave monitoring and controlling devices from a plurality of main monitoring and controlling devices can be easily constructed.
