Description
Technical field
The present invention relates to a kind of communication system, relate in particular to a kind of communication system for down-hole mechanical equipment.
Background technology
The equipment job sites such as down-hole development machine, coal-winning machine are in the mine of below ground, generally do not have the mobile network and cover.The scope of operation can reach 10km apart from ground under some equipment raises, for realizing the monitoring to underground work machinery, just must solve Communication.
In theory, there is various ways to realize, as: whole adopt wireless communication mode, lay special-purpose CAN telecommunication cable, based on the telephone line transmission of 52K modem, developing from pas network etc., these several main communication modes are compared:
1. integral body adopts wireless communication mode, developing from pas network: all data of this two schemes and voice transfer all rely on Radio Link, underworkings is broad not as ground, the passage bent angle is many, and wireless signal very easily is interfered under nlos environment and unstable; Need to arrange a plurality of wireless relay, increased the expense of later maintenance;
2. lay special-purpose CAN telecommunication cable: cross section 1.5mm
2
Approximately 6.8 yuan/meter of twin-core twisted-pair cables, every kilometer needs about 7000 yuan of cable expenses, and can increase along with the propelling of equipment work, also needs to increase the CAN relaying when communication distance surpasses 7km, the whole system cost is quite expensive, has improved excavate costs;
3. based on the telephone line transmission of 52K Modem: use original telephone wire in the mine, cost is the cheapest, but transmission when can not realize voice and data, can't use the down-hole phone in the time of the transmission of data, to stop transfer of data when making a phone call, consider not too to be fit to use based on fail safe, convenience.
In addition and since the equipment such as silo shearer be in mobile in, and the coal excavation apparatus afterbody will lay the hydraulic support about 100 meters, inconvenient wiring, thereby 2. and 3. above scheme be wired connection, is used for also existing inconvenience herein.Thereby, need a kind of communication system that is applicable to downhole operation equipment and ground communication, the transmission of data of exploitation.
Summary of the invention
The object of the invention provides a kind of communication system for down-hole mechanical equipment, use this communication system can make things convenient for the transmitted in both directions of ground and downhole data, and cost is lower, does not affect original speech communication, and is safe.
For achieving the above object, the technical solution used in the present invention is: a kind of communication system for down-hole mechanical equipment, comprise wireless transmission part and wire transmission part, the master controller of each equipment partly is sent to the chromacoder place with data through described wireless transmission, and this chromacoder is connected with ground telephone set and data receiver through described wire transmission part; Described chromacoder comprises a modulator-demodulator and a serial server with the wireless data sending function, described serial server receives and sends described modulator-demodulator to from the data-signal of described master controller and through Ethernet, the down-hole telephone set is connected with this modulator-demodulator through telephone wire, described modulator-demodulator is connected with an ADSL repeater through telephone wire, again through telephone wire and DSLAM equipment connection, described landline phone machine is by telephone wire and this DSLAM equipment connection, and described data receiver is through Ethernet and this DSLAM equipment connection.
In the technique scheme, each equipment of down-hole comprises development machine, coal-winning machine etc., when the work of this kind equipment need to ground Surveillance center swap data.Among the present invention, the mode that adopts wireless transmission to combine with wire transmission realizes the transmission of data, freely movable when not affecting each equipment availability, adopt the wireless transmission part to be connected with chromacoder, the signal data that sends in the equipment master controller is packaged into the TCP/IP packet by serial server, send modulator-demodulator (digital signal is converted to the defeated analog signal of phone line) to through the Ethernet cable, originally the intrinsic telephone set in down-hole also accesses in this modulator-demodulator simultaneously, in the lump in telephone wire is sent to the ADSL repeater, signal on the telephone wire is carried out power amplification, to promote communication distance, be sent at last DSLAM equipment, voice signal on the telephone wire is separated with data-signal, data-signal is reduced into the TCP/IP packet, send to data receiver (PC/Surveillance center), voice signal sends to the landline phone machine.Owing to adopting the ADSL technology, can when an ordinary telephone line is answered, called, carry out ADSL transmission and be independent of each other, thereby realize the two-way transmission of ground and downhole data signal, only need use the intrinsic telephone wire in down-hole and just can finish, need not to drop into the expense of rewiring.
In the technique scheme, described wireless transmission means is divided and is comprised a protocol converter with radio function, and this protocol converter is connected with the master controller of each equipment through the CAN bus, is connected with described serial server through wireless network.Protocol converter converts the CAN protocol frame that master controller transmits to the Modbus protocol frame, and be packaged into wireless data packet, mail to serial server, serial server is bundled into the Modbus protocol frame with the wireless data packet solution, and is packaged into the TCP/IP Packet Generation to modulator-demodulator.
Further technical scheme is, described protocol converter is arranged with an explosion-proof tank outward, increases fail safe.
In the technique scheme, the road between described modulator-demodulator and the described ADSL repeater is 3～5KM.
In the technique scheme, also be provided with electrical isolation grid in the described chromacoder, described down-hole telephone set is connected with described modulator-demodulator through these electrical isolation grid, is used for isolation from the non-intrinsic safety electric signal of modulator-demodulator, prevents that it from having influence on the work of telephone set.
In the technique scheme, described chromacoder and described ADSL repeater are arranged with respectively an explosion-proof tank outward, increase fail safe.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1, the present invention adopts the communication modes that wireless transmission combines with wire transmission, wireless transmission partly makes things convenient for the freely movable of underground equipment, but also real-time transmission data during mobile operating, original telephone wire is partly used in wire transmission, adopt the ADSL technology, in the situation that do not affect original voice call communication, realize the in the lump transmission of device data, realize that with the ground monitoring center bi-directional data transmits;
2, owing to the telephone wire by means of the mine indispensability, need not to rearrange cable, realize the multiplexing of down-hole voice and transfer of data, greatly saved the communication system cost.
