The main CPU unit 1 loads a program from the program holding unit 2 and operates using the system memory unit 3. As processing, when receiving the change data of the terminal device from the multiplex transmission control unit 5, the transmission control unit 10 makes a voice data input request or a voice data output request.

Next, the operation will be described with reference to FIGS. The main CPU unit 1 loads a program from the program holding unit 2 and operates using the system memory unit 3. In the system memory unit 3, a main CPU
In addition to the work area 1, there is an interlocking setting table as shown in FIG. 4 which is set in advance from a host computer or a setting tool and a terminal status table of each terminal. The interlocking setting table executes image capture and voice input. For example, conditions such as "terminal A and terminal B are true" and "terminal A is true and terminal C is false" are registered. If the condition is satisfied, image capture and voice input are performed. The terminal status table stores the status of the terminal connected to the current multiplex transmission.

As shown in FIG. 4, the multiplex transmission control unit 5 checks the normal operation of each terminal through the multiplex transmission cable 4 to monitor the status of each terminal and checks the normal operation of the terminal. Is performed, the terminal device obtains the status data of the terminal device, and transmits the obtained address and status data of the terminal device to the main CPU 1.

[0036] This makes it possible to take in an image and input / output sound according to the interlocking condition of a plurality of terminals connected on the multiplex transmission.

[Fourth Embodiment] The basic configuration of the equipment controller of the present embodiment is very similar to that of the first embodiment, and the same parts are denoted by the same reference numerals. , And a detailed description thereof will be omitted.

Here, the three blocks of the transfer control unit 10, the image compression unit 9, and the A / D conversion unit 8 combined with the camera unit 7 are the same as in the second embodiment described above. A configuration in which a microphone 15 and a speaker 16 are combined with the block of the transfer control unit 10, the A / D conversion unit 8, and the D / A conversion unit 17 may be employed.

Next, the operation will be described with reference to FIG.
The main CPU unit 1 loads a program from the program holding unit 2 and operates using the system memory unit 3. The multiplex transmission control unit 5 checks the normal operation of each terminal through the multiplex transmission cable 4 to check the normal operation of each terminal, and when the terminal generates an event, inquires about the event occurrence address. Data is acquired, and a process of transmitting the acquired address and status data of the terminal device and time data at the time of event occurrence to the main CPU 1 is performed.

The main CPU 1 has a plurality of processing tasks. Among them, there are an event monitoring task, an image capturing task, a host transmission task, and the like.

As shown in FIG. 5B, the event monitoring task confirms whether or not the status has been registered in the event table when the terminal device changes state, and notifies the host transmission task if the status has been registered.

As shown in FIG. 5A, the image capturing task always executes image capturing processing during the idle time of the CPU, and sequentially stores the captured image data in the system memory together with the time information at the time of capturing. When the reserved buffer becomes full, the image data is sequentially updated from the oldest image data.

When the host transmission task receives the address and status data of the terminal in which the event has occurred and the time data at the time of occurrence of the event, as shown in FIG. The closest image data stored in the system memory after the time data value at the time of occurrence is transferred to the host computer.

Here, as for the scheduling of each task, as shown in FIG. 5D, when no processing is normally performed, image input processing is performed. A state change occurs in the terminal,
If it is determined that the change is an event in the transmission control processing task, the transfer processing task is executed to transfer the image data to a host computer or the like. (If there is a processing task with a higher priority than the transfer processing, it can be executed first.) Thereby, there is almost no time lag between the time when the event occurs in the terminal connected on the multiplex transmission. In this state, it is possible to capture images and voice.

[Fifth Embodiment] The basic configuration of the equipment controller of the present embodiment is the same as that of the first embodiment, and a detailed description thereof will be omitted.

Next, the operation will be described. The multiplex transmission control unit 5 checks the normal operation of each terminal through the multiplex transmission cable 4 to check the status of each terminal and checks the normal operation of each terminal. Data is acquired, and a process of transmitting the acquired address and status data of the terminal device to the main CPU 1 is performed.

The main CPU unit 1 loads a program from the program holding unit 2 and operates using the system memory unit 3. As the processing, when the change data of the terminal is received from the multiplex transmission control unit 5, a request for image data is made to the transfer control unit 10.

As shown in FIG. 6, the transfer control unit 1
At 0, when a request for image data is received from the main CPU unit 1, a start command is transmitted to the image compression unit 9. The image compression unit 9 sequentially compresses two-field image signals input continuously from the camera unit 7 and digitizes them by the A / D conversion unit 8, and transfers the two-field separately compressed data. The data is transferred into the system memory through the control unit 10.

The transferred image data can be transmitted to the host computer 13 through the transmission cable 14 when the transfer is completed, and can be stored in the system memory and can be stored in the system memory when necessary. Can also be sent to When displaying an image on the host computer, the image data which has been divided into two fields and compressed is decompressed, and each field image data is combined with one frame of image data and displayed on the screen. Here, as the synthesizing process, a buffer is allocated, and the data is synthesized by expanding data of the odd field and the even field in the allocated buffer.

Thus, when a still image is captured, the processing of synthesizing the field image data into one frame image can be performed not by the controller but by a high-performance host computer.

[0051]

As described above, according to the first aspect of the present invention, by combining the multiplex transmission and the image capturing function, one terminal can be connected to the equipment controller.
This eliminates the need for wiring on a one-to-one basis, thus improving the workability.

According to the second aspect of the present invention, since the multiplex transmission and the voice input / output function are combined, it is not necessary to wire all the terminals and the equipment controller in a one-to-one manner. It has the effect of saying

According to the third aspect of the present invention, in addition to the effects of the first or second aspect of the present invention, it is possible to perform image capturing and audio input / output processing in accordance with the interlocking condition of a plurality of terminals. It has the effect of being able to do it.

According to the fourth aspect of the invention, in addition to the effects of the first or second aspect, when it is desired to capture an image when an event of a terminal device occurs, the event is continuously transmitted to a plurality of terminals. Even if a task having a high priority is generated, it is possible to minimize the time lag of the image taken in association with the event of the terminal device.

According to the fifth aspect of the present invention, it is possible to reduce the cost of the equipment controller and reduce the processing load by processing the still image frame synthesizing process by the host computer with high performance. It works.
