Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an information delivery system in an electronic automatic switching system, and more specifically, to a system for transmitting information between a central control unit and peripheral devices in an electronic automatic switching system under software program control. Regarding information delivery method.

[Background of the invention]

The central control unit in a conventional electronic automatic switching system reads and receives information between peripheral devices such as subscriber circuit equipment, trunk equipment, register equipment, and signaling equipment through a scanning device and through a drive device. It was driving.

The central control unit controls the time interval and timing for scanning the scanning device, the order and scanning position of the scanning device, and the time interval and timing for driving the driving device, the order of the driving device, and Each drive position etc. was determined and processed. This means that the operating patterns of all the devices that exchange information with the central control device must be incorporated into the program. Therefore, in the conventional technology, as the number of new types of devices and models that exchange information with the central control device increases, the large-scale program that commands the central control device that controls the operation of the transfer system is updated every time. This method has the disadvantage that corrections must be made, and if the corrections are made incorrectly, it can cause serious adverse effects on the entire system.

Next, the prior art will be explained in more detail with reference to the relay system of the conventional electronic automatic father changer shown in FIG. 1st
In the figure - SUB is the subscriber, 1 is the switch network, 2 is the MFC sender, 3 is the MP'
Use C register.

4 is a register sender drive, 5 is a register sender scanner, 6 is a scan drive, 7 is a trunk scanner, 8 is a file memory, and 9 is a central controller.

10 is a memory, 11 is a terminal device, and 12 is an L
It is a PP trunk, and 13 has a LP person rank.

14 is a transmission register, and 15 is a trunk drive device. In Figure 1, when subscriber SUB makes a call,
The subscriber terminal of the switch network 1 becomes in a calling state. The central control unit 9 sequentially executes processing operations based on commands of the program stored in the file memory 8, and upon receiving a command to scan the call status of the subscriber SUB, the central control unit 9 performs a scanning drive. The device 6 is used to search for a subscriber SUB f whose calling terminal on the switch network 1 is in a calling state. The scanning drive device 6 receives an instruction to scan the calling subscriber terminal from the central controller 9, forms a scanning signal from the scanning instruction from the central controller 9, and determines whether the subscriber terminal is in the calling state or not. Scan one by one to find subscriber terminals that are in a calling state. When a power input terminal in the state of one call is found, the scanning drive device 6 converts the scanning signal into an instruction response that can be read by the central control device 9 and outputs it. When the central control unit 9 learns of the call origination of the subscriber SUB, it then learns the calling register 14 which is calling 2+, -, according to the instructions of the program.

The register sender scanning device 5 is instructed to scan the transmission register 14. The register scanning device 5 converts the instruction contents into a scanning signal for the transmission register 14, scans the empty space in the transmission register, converts the result into an instruction response that can be read by the central control device 9, and outputs the result to the central control device 9. Subsequently, the central control device 9 causes the scanning drive device B to scan the switch network 1 in order to find out the push channel in the switch network 1 that can connect between the υ call terminal and the call register 14 according to the instructions of the program.

Based on the result, the central controller 9 causes the scanning driver 6 to close the channel connecting the calling terminal and the calling register 14. Hereinafter, this will be referred to as all channels A.

When the dial tone is heard from the calling register 14 to the subscriber name SUB via the channel Af in the switch network 1, the central control unit 9 sends a message to the register sender scanning device 5 to know the dialed number of the subscriber SUB. Perform a scan and receive the results. That is, the central controller 9 reads dial pulses from the calling subscriber received by the calling register 14 via the register sender scanning device 5 at regular intervals according to instructions from the program. The central control unit 9, as instructed by the program, completes the reception of the predetermined Atayal digits and, when it is time to connect to the subscriber of another station, instructs the trunk scanning device 7 to scan the LPP trunks 12 present. Similarly, scanning of vacant MFC senders 2 is also commanded. Next, the central processing unit 9 attempts to connect the empty LPP trunk 12 and the empty MFC sender 2 using a channel within the switch network 1.

Instructs the scanning drive device 6. This channel will be referred to as channel B hereinafter. Then, the central control device 9 causes the MFC sender 2 to send connection code information necessary for connection at the rear end to the MFC sender 2 via the scanning drive device 6 and the register sender drive device 4 according to instructions from the program. . When the central control rack @ 9 completes sending out the connection signal information, it first sends the call terminal and the LPP trunk 12 to the channel in the switch network 1 via the scanning drive device 6.
connect with. This channel will be referred to as channel C hereinafter. Of course, channel AB in the switch network 1 is opened at this time.Next, the central control unit 9 monitors the abandonment of the calling subscriber SUB or the response of the called party at regular intervals according to the instructions of the program. Then, the trunk scanning device 7 scans the LPP trunk 12.

Even after the called party answers and the call is entered, the central controller 9 continues to monitor the calling party SUB and the called party using the trunk scanning device 7 as instructed by the program. Even if the call ends and the LP output trunk 12 becomes stuck, the central controller 9 always monitors that the LP output trunk 12 is free.7 As described above, the central controller 9 uses the file memory The operation processing of the entire conversion system is executed according to the program stored in the central control unit 8, but the program includes all the operation processing patterns, judgment criteria, monitoring status, etc. that the central control unit 9 should execute. It is necessary to program down to the detailed state transitions, etc. Therefore, the disadvantage is that the program in the file memory 8, which controls the operation processing of the exchange system, must be modified each time the models of ingress/egress trunks increase due to differences in line signals, or the models of registers and senders increase due to differences in register signals. Yes.

[Purpose of the invention]

The present invention was developed in view of the above-mentioned drawbacks of the prior art, and when changing nine models in which new types of peripheral devices are added to the electronic automatic switching system, the program that controls the overall operation of the electronic automatic switching system is modified. The purpose of the present invention is to provide an information delivery system in an electronic automatic switchboard that can be operated without any need for a system.

[Summary of the invention]

The information delivery method in the electronic automatic switching system of the present invention is such that in the electronic automatic switching system equipped with a central control unit and various peripheral devices, software program control is performed to control the unique operations of the various peripheral devices described above. It is characterized in that information is exchanged between the central control unit and various peripheral devices using the same format.

[Embodiments of the invention]

The present invention will be explained in more detail below with reference to the accompanying drawings. In the following embodiment, an outgoing trunk of one peripheral device will be explained as an example.

Fig. 2 is a diagram showing an example of a conventional outgoing trunk, where A is a position relay, E is a rear response monitoring relay, M is a rear loop monitoring relay, S is a signal closing relay, and T is a communication path closing relay. Each relay is shown. When the outgoing trunk is empty, the relay M is activated via the relay wire by the downstream device metal loop circuit (terminal A1 → switch t2 → switch S2 → relay M → switch IN3 → switch t3 → terminal B1). Operate. To determine whether the outgoing trunk is stuck or in use, the central controller sends a message to the trunk scanning device via terminal TQ,
TI and terminal T2. Judgment is made by reading the state of T5. When the central control device captures the outgoing trunk, a signal from the trunk drive device is input through the terminal T4f, driving the relay S that closes one signal path, and one terminal AO, EO → contact tQ, t1 → contact s2.53 → contact t2. A series of circuits at t3 are connected. As a result, the connection code necessary for the subsequent connection input to the terminals AO and BO on the switch network side is outputted from the terminals AI and β1. When the central controller completes sending the connection code to the downstream.

Drive the communication path closing relay T through the trunk drive device, terminals AO, BO-+ contacts tQ, tl-p contacts GO.

S1→contact t2. ts→terminal A1. A communication path consisting of El is closed. As a result, position relay A operates in a loop circuit via the 9-output power loop. When position relay A operates, the circuit of terminals TO and TI is closed by contact α, and the trunk scanning device monitors this at regular intervals.

Monitor caller abandonment. On the other hand, when the connection is completed at the downstream station and the called party answers, the line AL of the downstream station,
Reversal of BL activates rear response monitoring relay E, and terminals T2. The circuit of T5 is closed again. The central controller reads this through the trunk scanning device and knows the called party's response. After starting one conversation, the central controller communicates with the nephews TO, TI and the terminal r2. r
The state of the loop closure of No. 5 is monitored to see if the calling party has lost any trace, and the termination of the call No. 5 is known. The above-mentioned state transitions are all programmed for each model and type and stored in a file memory to control the entire conversion system.

FIG. 3 is a diagram showing an embodiment of the present invention), and the same parts as those in FIG. 2 are given the same reference numerals, and the explanation thereof will be omitted. What is different from the conventional example shown in FIG.

A one-chip processor 100 incorporating a program for identifying and controlling each operation pattern of a position relay A, a rear response monitoring relay E, a rear loop monitoring relay M, a communication path closing relay T, and a signal closing relay S. is provided.

Data is directly exchanged between this one-chip processor ioo and the central control unit only when necessary. Data is exchanged with the central control unit using data such as whether the outgoing trunk is in use or sending a signal, the status of the calling party, and the status of the called party. No matter how the circuit configuration changes, the data formats between the central control unit and the outgoing trunks should not change.

When a new model with a different outgoing trunk circuit configuration is used, a program built into the one-chip processor 100 unifies data exchange with the central control unit. By doing so, new models can be added without modifying the program that issues commands to the central control unit that controls the entire switching system. Of course, this invention can be applied not only to outgoing trunks but also to incoming trunks, registers, senders, etc.

As is clear from the above description, the present invention provides peripheral devices such as outgoing trunks, incoming trunks, MFC senders, and MFC registers with a control function that controls the individual operations of each peripheral device. Information can be exchanged between central control units using data in the same format.

Therefore.

Even if the line signals, register signals, received digits, etc. of each peripheral device change, there is no need to modify the program for the central control unit, and one type of peripheral device can be easily changed or added.

According to the present invention, it is possible to shorten the information transfer time between the central control unit and peripheral devices, improve the processing capacity of the central control unit, and simplify the configuration of the program for the central control unit.
