Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a remote control method for loading a program stored in an auxiliary storage device into a main storage device in order to bring a slave exchange into service operation in an automatic telephone exchange. It is related to the method.

[Conventional technology]

Conventionally, in this type of remote control method, the first
As shown in the figure, the master station's auxiliary storage device (M-SM)
11 and a slave station auxiliary storage device (S-SM) 12 are composed of magnetic tape storage devices. M-SM
Read information from 11 and main memory (MM) 15
In the case of storing M-SM1 in the slave station,
A magnetic tape that stores control information for reading information from 1 is set in the S-SM 12, and the master station sets the magnetic tape that stores information necessary for switching control to the M-SM 12.
Set to SM11. After that, by manipulating the read operation request signal (MIPL) 17 at the master station, the control device (CC) 14 of the slave station detects it as an operation request from the master station, and starts the information transfer device (CH) 13. Send the S-SM number to CH13. CH1
3 starts S-SM12 by S-SM number,
When the control information stored in the magnetic tape set in the S-SM 12 is read out for the MM 15, the CC 14 then refers to the information on the MM 15 and reads out the control information stored in the magnetic tape set in the S-SM 12.
The M-SM 11 is activated by the M-SM number, and the stored information is read from the MM 15 from the M-SM 11 in the same manner as described above, thereby completing the operation in response to the read operation request.

[Problem to be solved by the invention]

Therefore, when making an operation request at the master station, it is necessary to set the magnetic tape at the slave station, but in this type of remote control system, the slave stations are usually unmanned stations and are quite far away from the master station. In reality, the current situation is that the magnetic tape is moved to the slave station and the magnetic tape is set, as well as an operation request is made at the slave station. Furthermore, if the MM memory contents are destroyed due to a failure such as a power outage or malfunction, replacement control becomes impossible, so it is necessary to read information to the MM immediately, but the current drawback is that it takes a considerable amount of time.

The purpose of the present invention is to set the operation request signal of the master station so that the information transfer device is always activated with the S-SM number, and convert it to the M-SM number only when the operation request signal is set. The present invention provides a remote control method that solves the above-mentioned drawbacks and allows information read operations to be performed only by operations at the master station, by controlling the read operation and resetting the operation request signal of the main storage device upon completion of the read operation. It's about doing.

[Means to solve the problem]

The remote control method of the present invention sets an operation request signal to be sent by the master station in the slave station, and after the set output is guaranteed to have been received by the information transfer device, the operation request signal and the operation request to be sent by the slave station are set. The control device sends the slave station number to the information transfer device by ORing with the signal, and the information transfer device transmits the slave station number to the master station only when the operation request signal of the master station is set. After conversion to a number, the auxiliary storage device is activated, and the main storage device resets the operation request signal of the master station when the operation is completed. When the master station requests an information read operation, the slave station It is characterized by not requiring any operation.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 2 is a block diagram showing one embodiment of the present invention, and the case where information is read from the auxiliary storage device (M-SM) 11 of the master station to the main storage device (MM) 15 will be explained. Auxiliary storage device of slave station (S-
M-SM1 is a magnetic tape that stores control information for reading information from SM) 12, information necessary for exchange control, and reset control information for the master station's operation request signal storage circuit (RG) 21 upon completion of the read operation.
Set to 1. By manipulating the read operation request signal (MIPL) 17 of the master station, the slave station sets this signal in the RG 21 and inputs the set output to the information transfer device (CH) 13. Also, the MIPL signal 17 is connected to the delay circuit (DL) 22.
is input. The DL 22 generates an output after a period of time until the set output of the RG 21 can be read by the CH 13, and inputs it to the control device (CC) 14. Next, CC14 uses CH1 according to the S-SM number.
Start 3. CH13 receives the received S-SM only when the output of RG21 is in the set state.
Convert the number to M-SM number, then M-SM
11. The S-SM for MM15
When the control information for reading information is read from the CC 12, the CC 14 refers to the information in the MM 15 and activates the CH 13 using the S-SM number as described above. Therefore, information necessary for exchange control and RG reset control information upon completion of the read operation are read from the M-SM 11 to the MM 15. MM15 resets RG21 upon completion of the chaotic operation.

Next, an example of a specific implementation circuit will be explained with reference to FIG. When the MIPL electric switch 17 is operated at the master station, the M0 relay operates at the slave station, and then the M1 relay operates. After that, when the MIPL electric switch 17 returns, the M0 relay is restored, and while the M1 relay is slowly and slowly restored, the M2 relay operates, and then the M
3 relays operate and maintain self-holding. IC1 via ICO of CH13 is set to logic 1 by M3 relay operation. Thereafter, when the M1 relay is restored and an operation request signal is sent to the CC 14 while the M2 relay is slowly recovering, the CH 13 is activated as described above. Next, CH13 reads the set IC1 output with the control circuit, and only if it is at logic 1 level,
Outputs SET signal. This SET signal causes IC2
When the via IC3 is set to logic 1, the S-SM number received from the CC 14 is masked since the output of IC4 is logic 0, so the output of IC5 is also logic 0. on the other hand
M-SM by connecting IC3 output to IC6
The number is sent to S-SM via IC7. After confirming that the M-SM has started up normally, the control circuit sends out a RESET signal to reset the IC3.
When the output of IC3 becomes logic 0, IC6 is masked,
On the other hand, the gate of IC5 is opened and used as a circuit for subsequent information transfer. The MM 15 operates the RST relay upon completion of the information read operation.
M3 relay is restored by RST relay operation, and CH
IC1 returns to logic 0.

〔Effect of the invention〕

As explained above, the present invention assumes that the information transfer device of the slave station is activated by the slave station number, and in the case of an operation request of the master station, it is configured to convert to the master station number and activate the auxiliary storage device. This has the effect that when an operation is requested from the master station, the operation can be completed without the need for operation of the slave station.
