The present invention is composed of a dispatching control device and a dispatching terminal and can be used as an auxiliary device of a stored program control exchange. When the present invention is attached to a stored program control exchange, the software and the hardware of the stored program control exchange can be modified at a small degree so that the dispatching terminal comes into contact with a branch dispatching appliance of the stored program control exchange through a dispatching control device; as a result, state information and control information are transferred. The stored program control exchange is integrated with a dispatching appliance, and the stored program control exchange has the function of production dispatching; as a result, the goal of one appliance with two purposes is actually reached.
Description
The present invention relates to a kind of communication product, particularly a kind of production scheduling equipment.
Production scheduling equipment is that enterprise carries out the requisite communication apparatus of modern production.In present widely used communication exchange device, exchange plant and production scheduling equipment are equipped with respectively, and exchange plant does not possess scheduling feature.Though production scheduling equipment has certain function of exchange.But compare with subscriber exchange, also have many difference on its performance, also far do not reach the essential performance of subscriber exchange, enterprise wants independent networking in order to guarantee the unblocked of various communications, causes the waste of overlapping investment and resource.
The objective of the invention is to overcome the deficiency of SPC PBX, design a kind of production scheduling equipment, by revising the software and hardware of subscriber exchange slightly, and itself and subscriber exchange subscriber line circuit are coupled together, make subscriber exchange have the production scheduling function simultaneously.Reach user's exchange, the two purpose that really integrates of production scheduling.
The present invention mainly is made up of scheduling controlling equipment and dispatch terminal equipment two parts, and it sees accompanying drawing 1 with being connected of stored-program control exchange.Dispatch terminal is connected with scheduling controlling equipment with serial ports by speech channel.Serial ports is used for transmitting dialing information and relevant control and state information, scheduling controlling equipment is connected with dispatch terminal on the one hand, its speech channel is connected with the stored-program control exchange subscribers feeder on the other hand, transmit relevant controlling information between its serial ports and the stored-program control exchange, be connected to finish group calling with each scheduling extensions subscribers feeder in a meeting dedicated link and the stored-program control exchange simultaneously, exhale together and function such as conference dispatching.Each master scheduling is by dispatch terminal, and each the extension set scheduling of scheduling controlling equipment and programme-controlled exchange exchange is got in touch.
The present invention requires program controlled user exchange software and hardware is done minor modifications, and to adapt to the needs of production scheduling, its major requirement is:
1. need provide a serial port so that communicate with scheduling controlling equipment.
2. stored-program control exchange extension set dispatched users line connects with scheduling controlling equipment meeting dedicated link and its break-make is subjected to the control of the microprocessor of stored-program control exchange.
3. should have " hot line " and " preferentially " function with the master scheduling conversation.When extension set dial the master scheduling number or when behind the scheduling extensions off-hook beyond the defined dialing time, as long as there is idle master scheduling to send ringing-current from trend scheduling controlling equipment.When the whole links of stored-program control exchange all take, should roll over a link by force and give relevant extension set.
4. scheduling controlling equipment has " preferentially " and " intrusion " function.Behind the master scheduling off-hook, no matter whether stored-program control exchange has idle link all should distribute a link to give the master scheduling user, and after the master scheduling dialing when if scheduling extensions is just busy, should insert by force and this scheduling extensions conversation.
Dispatch terminal is mainly by microprocessor unit; Keyboard; Compositions such as display unit and speech path equipment unit.Dispatch terminal is microprocessor keyboard scan ceaselessly in the course of the work, and when having detected key and press, microprocessor mails to scheduling controlling equipment to this key scanning sign indicating number by serial port.To the relevant state information that the scheduling control appliance is sent here by serial ports, microprocessor analysis judges that the back shows for information about on display terminal, so that master scheduling is understood each scheduling extensions state at any time.
Scheduling controlling equipment is mainly by microprocessor unit; The interface decoding unit; Impedance conversion; The ringing-current detecting unit; Letter bell equipment; The meeting amplifying unit; Net continues; The master scheduling detecting unit; Language processing unit; Detecting signal unit; The sending and receiving unit; Music, signal source; Compositions such as real-time clock unit and serial port.The ringing signal that the ringing-current detecting unit is sent here the exchange subscribers feeder detects, so that microprocessor is handled accordingly.Exchange subscribers feeder and the isolation that continues and net are realized in the impedance conversion unit; When master scheduling and extension set scheduling conversation, provide low ohmic loop simultaneously for the exchange subscribers feeder.Usefulness when the meeting amplifying unit mainly is scheduling meeting and group calling because it is more to participate in the extension set dispatched users of having a meeting when holding a meeting, must be amplified speech current.Speech current after the amplification is stronger, can not be by the net that continues of stored-program control exchange, so directly be connected on the subscribers feeder of stored-program control exchange extension set scheduling drawing a dedicated link on this meeting amplifying circuit, and its break-make is subjected to the control of stored-program control exchange microprocessor.The function of net of continuing is to realize temporary transient connection between stored-program control exchange subscribers feeder and the master scheduling according to the instruction of microprocessor.The major function of master scheduling detecting unit is to provide to microprocessor that master scheduling is plucked, hook state information.The function of sending and receiving unit is that the double-audio signal of receiving scheduling terminal use phone carries out analyzing and processing for microprocessor, send double-audio signal by the net that continues to user's main exchange under the control of microprocessor instruction.The effect of language processing unit is to work in coordination with detecting signal unit, sending and receiving unit after the speech of master scheduling is dynamically recorded, and finishes relevant extension set automatically and dispatches the processing of calling out, converse.The effect of music, signal source is relevant warning tone to be provided for before formal meeting when master scheduling is held port operation meeting or group calling each extension set scheduling, and letter bell equipment sends the sound when the exchange subscribers feeder comes ringing-current, notify each master scheduling to handle.Serial port is in order to transmitting control and state information between scheduling controlling equipment and program controlled user machine and scheduling controlling equipment and each dispatch terminal.
Scheduling controlling equipment is when work, microprocessor ceaselessly scans ringing-current control unit and master scheduling detecting unit, when finding ringing-current is arranged, little processing controls letter bell equipment sounding notice master scheduling off-hook is replied, when scheduling controlling equipment send ringing-current, send the number of off-hook extension set scheduling at SPC PBX here to scheduling controlling equipment by serial port.After microprocessor is found the master scheduling off-hook, microprocessor unit at first judges currently whether have ringing-current to send here, net is connected this master scheduling and is dispatched with relevant extension set if ringing-current is arranged then little processing controls continues, by serial port the extension set scheduling of conversing is sent to each dispatch terminal with the master scheduling number simultaneously, on the display of dispatch terminal, shows for information about; So that each master scheduling is grasped the state of each scheduling extensions at any time.Judge currently when not having ringing-current when microprocessor, then select a coupled idle exchange subscribers feeder, by the net that continues it and dispatch terminal are connected, while control group converter unit makes it be in low resistive state; At this moment stored-program control exchange send dialing tone to this dispatch terminal, and master scheduling can dial after hearing dialing tone, can connect relevant scheduling extensions after the dialing.
The dialing of master scheduling can by the double-tone on the dispatch terminal frequently phone or keyboard send, when phone sent frequently by double-tone, can be scheduled sending and receiving unit in the control appliance of this number received the back and handles for microprocessor unit.When microprocessor unit judged that this number is represented control information or inter-process, microprocessor carried out relevant processing on the one hand, and the control group converter unit is in high-impedance state on the other hand, and making this subscribers feeder is idle condition.When master scheduling is passed through the keyboard dialing of dispatch terminal equipment, then the scan code of keyboard is sent by serial port by the microprocessor on the dispatch terminal equipment, after the microprocessor on the scheduling controlling equipment receives this scan code, if through judging that this scan code represents a certain scheduling extensions number, then microprocessor control sending and receiving unit by the net that continues to programme-controlled number.
When microprocessor judges went out coded representation conference dispatching that dispatch terminal sends here or group calling, in order to reduce the required time of dialing, each extension set scheduling number transmitted to exchange by serial port.At this moment, on the one hand scheduling controlling equipment matches with exchange and inserts the input of meeting amplifying unit by the net that continues again after leader's extension set and the master scheduling connection, so that leader's extension set and master scheduling can arbitrarily be made a speech when having a meeting.On the other hand exchange one by one to relevant extension set scheduling ring, behind the extension subscriber off-hook, the action of exchange control corresponding relays is connected this extension line with the dedicated link of meeting amplifying unit.Master scheduling is sent to relevant extension set scheduling by this dedicated link with leader's speech after amplifying.
When scheduling controlling equipment is in automatic call conversation state, microprocessor detects at the detecting signal unit output and dials sound and number control sending and receiving number unit later on seriatim and dial to exchange, microprocessor detects relevant extension set by detecting signal unit and whether dispatches off-hook then, and microprocessor starts linguistic unit and emits the speech of prerecording when detecting off-hook.Repeat said process up to relevant each all conversation of extension set scheduling.
In order to reduce to the index word of SPC PBX software and to the taking of its resource, the spy is provided with music, signal source and real-time clock unit separately in scheduling controlling equipment in the present invention; Though for the present invention they and nonessential.
Though the present invention is connected on the subscribers feeder of stored-program control exchange in this explanation, the present invention also can be connected on the trunk line of stored-program control exchange in principle.
Advantage of the present invention: use the present invention.Change to former SPC PBX software and hardware is less, only need to revise simply on a small quantity just can unite two into one user's stored-program control exchange and production scheduling machine, reach the purpose of dual-use, because in the present invention, subscriber line circuit, switching network, repeat circuit etc. are all used original circuit in user's stored-program control exchange.So make user's stored-program control exchange have the very high ratio of performance to price, save user's great amount of investment, has high economic benefit, and convenient for users to use again because master scheduling generally is located near the production scene, and external environment condition is relatively poor, bigger to the influence that is installed in on-the-spot dispatching telephone control board, and the present invention can spatially be separated with exchange, can make exchange away from the production scene, thereby can improve its reliability, increase the service life.
