Abstract

The utility model discloses a wire or a wireless dispatching telecommunications. The main unit of the utility model is provided with double CPU, and the electric power source is provided with double electric back-up for improving the system reliability. The installed wireless module can be made for the deficiency wire communication; also can be switched in network in any position of wireless web covering signal area. The wireless web comprises a plurality of configuration methods for flexibly choosing according to requirement. Thereby, the wireless web is competent for a web from a small web with some users to a big web with more than thousands of users, and the wireless web is characterized in that the wireless web is provided with Roaming or the like, but wire web can not realized. The wireless web has the advantages of that the wireless web is not tied by cable and is movable, the wireless web can deal with the problem of difficult interconnections, less crowed socket connector and short circuit, furthermore, the wireless web connection is flexible, expand market is convenient, various web standards are compatible, and the investment of users can be protected, and the application scope is wide.

Description

Wired, wireless composite scheduling switch

Technical field

The utility model relates to a kind of scheduling switch, relates in particular to a kind of wired and scheduling switch wireless communication function of having simultaneously.

Background technology

The program control scheduling communication system is widely used in electric power, metallurgical, civil aviaton, public security, oil, chemical industry, the harbour, the mine, first-aid centre, the command scheduling of enterprises and institutions such as traffic, can satisfy the commander of enterprises and institutions, the scheduling requirement, because the program control scheduling communication system is being undertaken the critical function of enterprises and institutions' inner working, user side is generally away from several kms of master control system, though close together between the user who also has, but because floor at interval each other, hard obstruct such as wall, cause very difficulty of wiring, therefore construction period is the longest, surrounding enviroment are had the greatest impact, in work progress, often need brokenly wall to pick up, threading frame pipe is unfavorable for setting up fast of system.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of wired, wireless composite scheduling switch that has wireless communication function, reliable operation concurrently.

For achieving the above object, the technical solution of the utility model is: wired, wireless composite scheduling switch, the main control module that comprises the operation of coordination, control whole system and ancillary equipment, the power module of required operating voltage is provided for system, trunk module between main control module and public telephone network or other telephone networks, between main control module and landline telephone, wire module arranged, also include the wireless module between main control module and radio telephone; Described main control module is two CPU main control modules; Described power module is a duplicate supply.

As a kind of improvement, described wireless module comprises wireless receiving, radiating portion, data bus interface control and data conversion unit between wireless receiving, radiating portion and dispatching host machine.

Owing to adopt technique scheme, system host adopts two CPU, and system power supply adopts the duplicate supply backup, has improved the reliability of system; The setting of wireless module has not only remedied the deficiency of wire communication, and any one position can access network in the signal coverage areas of wireless network; Wireless network has the various configurations mode, can select flexibly as required.Like this, wireless network just can be competent at the catenet from the mininet that has only several users to thousands of users, and the characteristic that can provide picture cable network such as " roam (Roaming) " to provide.And not fettered by cable, removable, can solve the problem of bringing because of line difficulty, cable-to-cable connector become flexible, short circuit etc., and have networking flexibility, dilatation convenient, with plurality of advantages such as multiple network operating such, the existing investment of protection user, applied range, and: (1) networking cycle is short, the networking fast and flexible can be formed system point-to-point, point-to-multipoint as required; (2) anti-interference, anti-fading ability is strong, the high communication quality; (3) good confidentiality; (4) wide coverage; (5) Fast Installation, non-maintaining, antenna is small and exquisite.

Embodiment

As Fig. 1, Fig. 2, shown in Figure 3, wired, wireless composite scheduling switch, the main control module that comprises the operation of coordination, control whole system and ancillary equipment, the power module of required operating voltage is provided for system, the trunk module that realization connects with public telephone network or other telephone networks, can realize the wire module that has of Fixed Telephony function, also include wireless user and wireless user, the interior wireless user of net and wire user in realizing netting, net the wireless module of interior wireless user and main control module communication function; Described main control module adopts two CPU board of automatic detection, automatic switchover, automatic blocking faulty board; Described power module adopts the duplicate supply of automatic detection, automatic switchover, automatic blocking faulty board.

CPU coordinates, controls the operation of whole system and ancillary equipment as the control centre of system.System program is stored among the EPROM, behind the device start, automatically performs initialization and self-diagnostic program.Storage of subscriber data in having battery powered dynamic memory, after system's power down, will can obliterated data.System adopts two CPU board to carry out two Hot Spares, detection automatically, automatic switchover, automatic blocking faulty board; In the system, a CUP plate should be arranged at least, could move.

System adopts the duplicate supply Hot Spare, detection automatically, automatic switchover, automatic blocking faulty board.The power panel input voltage is direct current-48V, output voltage be direct current+5V ,-5V and exchange 75V.

As described in Figure 4, described wireless module comprises wireless receiving, radiating portion MC9S08GT, makes wireless receiving, radiating portion carry out the data bus interface control and the data conversion unit MC13192 of exchanges data with the scheduling main frame.

The course of work of wireless module is as follows:

When (wireless) user is moved in the fixed schedule call, dispatching host machine is delivered to MC9S08GT with signal by transmission channel (data/address bus), finish voice at wireless receiving, radiating portion after digital conversion by 16 ADC in 8 passage roads, be connected with the SPI of wireless receiving, radiating portion by four line SPI interfaces, become analog signal at the digital transceiver of wireless receiving, radiating portion and launch through simulating transmitting machine.

After wireless user's (moving) end is being received the wireless signal of main frame, the analog receiver of MC13192 arrives digital transceiver with the transmission of wireless signals that receives, after SPI four line data/address buss are delivered to MC9S08GT digital signal conversion are become analog signal, pass to speech ciphering equipment, set up conversation.

Equally, when wireless (moving) end makes a call to dispatching host machine, when setting up conversation, voice are delivered to 16 analog to digital converters of 8 passages through transmission channel, deliver to the SPI of MC13192 through the SPI of MC9S08GT, deliver to digital transceiver again, after digital to analog conversion, launch by simulating transmitting machine, after the radio-cell of dispatching host machine end receives the wireless signal that the wireless user sends, accept by the simulation receiver of MC13192, after digit receiver is done mould/transformation of variables, deliver to the SPI that SPI is transferred to MC9S08GT, deliver to the transmission channel (data/address bus) of main frame through the GPIO mouth, enter the switching system of dispatching host machine, set up conversation.
