Then, it waits for one cycle of control transmission to be completed. Since a transfer operation completion interrupt is generated when one cycle of control transmission is completed, it is determined whether there is an interrupt (S3).

If there is an interrupt, it is determined that one cycle of control 完了 has been completed, and the control information processor 16 gives a data car 5¾ start command to the transmission control circuit 14 (S 4). Specifically, the operation start address of the transfer setting table is written to the register 44 in the CPU interface circuit 38. In response to this, the transfer control circuit 14 The transmission control circuit 45 operates to perform an arrest process.

At the same time, the status change generating power was detected by comparing with the value of the information I data D 1 up to the previous time: ^ stores the generated address value. Here, “state change” means “state change”. The CPU interface circuit 38 outputs a DMA request signal (DREQ signal: Direct Memory Access Request signal) to the control information processing device 16 every time | 5¾ ends, and receives the control information processing! 16 Internal DMA circuit A request acceptance signal (DACK signal: Direct Memory Access Acknowledge signal) is returned, and the information output by the CPU interface circuit 38 on the bus signal d is stored in the RAM 25. At this time, the CPU interface circuit 38 outputs the updated information data and the previous state change occurrence data address value (no state change or no special state change data). This operation is performed a specified number of times.

The state change occurrence address value that occurred last is reflected in the register 44 inside the CPU interface circuit 38, and the control information processing unit 1 16 uses this value to determine the address where the state change occurred. It is possible to edit data at high speed. In the case of Ning “Information → Control”, the data is read from the information D5 indicated by the information address value, and stored in the relay control transmission data D3 according to the specified control address value. Perform this for the specified number of times. At the time when the status becomes “end”, the CPU interface circuit 38 sends a car_5¾ end interrupt to the control information processing unit 16.

Since such a method is employed, the control information processing unit 16 can execute other processing during the execution of the processing, and can realize an efficient operation.

In the conjunction control circuit 46: ^ The speech data is sent to the speech counter and the speech processing is started. Reads the data at the address indicated by the word counter 48 from the word buffer 49, and performs parallel conversion serial conversion on the word clock dividing circuit 4 7 力 {Performs according to the word cycle and sends it to the serial connection c. .

The word cycle is determined by using the force division correction data created from the basic cut-off value using the cut-off frequency division value, and further close to the required cut-off value. . For frequency division correction, change the frequency of frequency division according to the number of data processing positions. Frequency division).

In the word counter, the word count value is incremented and set each time one data is sent, and the value is compared with the message count value. When this value reaches the total count value, the command ends, the interrupt force S occurs, and the vehicle processing ends. The control information processor 16 receives the interrupt signal and performs end processing.

Next, the operation of the reception time chart will be described.

In the reception buffer 53, the reception data is written to the address position indicated by the reception power counter 52. At this time, the reception request data number is compared with the reception power number inside the reception power counter 52. When this value reaches the reception count value, a reception interrupt is generated. The control information processing unit 16 receives an interrupt signal and performs data read processing. Reception buffer 5 3 Data data S Each time S is read, the reception count is decremented. The control information processing device 16 reads data until the reception counter value reflected in the register 44 inside the CPU interface circuit 38 becomes zero.

By adopting such a receiving method, the serial receiving operation in the control information processing unit 16 is efficiently performed by continuously processing a plurality of received data.

In addition, the control information processing unit 3 can determine that an abnormality has occurred when the content of the control transmission system is not updated, so that the data on the information system can be initialized and notified that the state is abnormal. It becomes possible.

In the above description, the method of specifying the start position of the I ^ processing may be used, or the method of always using the head of the table may be used. In addition, the operation of "Control → Information j! ^" Is performed, and all data is output and address data is added only to data that has changed state. It is good also as a method of sending out only.

In addition, the elevator control transmission system described above can be applied to a system that controls a single elevator car, and can also be applied to a group system that controls a plurality of cars.

Further, as the frequency division value correction method of the serial 5¾ circuit, correction is performed using a value obtained by adding 1 to the frequency division value data, but a method of correcting the value by subtracting 1 may be used. Furthermore, it is good to use a value of the received data sample period (8 times the received clock value, etc.) as the division value to be set, and to add a value to the sample period. Also, in the data processing, a word end interrupt is generated when the set number of data is reached, but an interrupt is generated before the number of data is reached, and the time required for the interrupt processing time is advanced. It is also possible to have all vehicles end processing. Industrial use
