Description
Technical field
The present invention relates to the geological exploration fields such as oil, can be used for petroleum seismic prospecting system and there is big data quantity and carried out the system of data transmission by trunking scheme.
Background technology
The basic composition of petroleum seismic prospecting system: petroleum seismic prospecting system is primarily of host computer system and each acquisition station unit composition, and each acquisition station, by stube cable, is connected to main frame in a series arrangement one by one, forms a data acquisition link.On a data acquisition link, serial connection nearly hundreds of even thousands of acquisition stations, each acquisition station are equipped with microprocessor and multiple sensors, each acquisition station timing by the various data upload that collect to main frame.
Petroleum seismic prospecting system data communication mode: at present, the practical data transfer mode of petroleum seismic prospecting system adopts RS485 communication to carry out data transmission, and carry out done site by site force transfer with trunking scheme, namely image data to be passed to upper level (near main frame) acquisition station with RS485 communication mode by the data of next stage (namely away from main frame) acquisition station, each acquisition station one-level one-level force transfer, finally all image data are transferred to main frame, complete a data collection task.
The defect of petroleum seismic prospecting system data communication relay transmission mode: when on data acquisition chain, certain grade of acquisition station breaks down, when causing this grade of acquisition station normally can not pass data, the data of its following acquisition station at different levels all cannot be transferred to main frame by this level, thus cause whole data acquisition system (DAS) normally to work, when particularly carrying out petroleum prospecting at sea, because exploration operation cost is very high, this will bring about great losses.
Summary of the invention
For solving the problems of the technologies described above, the scheme that the present invention adopts is as follows:
A kind of oil seismic exploration data acquisition system (DAS), comprises acquisition station module, the telecommunication cable of host computer system module, plural serial stage connection, every grade of acquisition station is provided with telecommunication cable transfer relay.

Embodiment
As described in Fig. 1-3, a kind of oil seismic exploration data acquisition system (DAS), comprises acquisition station module 2, the telecommunication cable of host computer system module 1, plural serial stage connection, every grade of acquisition station is provided with telecommunication cable transfer relay 3.
Acquisition station module 2 comprises microprocessor system module 4, microprocessor system module 4 is connected with data receiver cable interface module 5, data sending terminal cable interface module 6 respectively, data receiver cable interface module 5 and next stage acquisition station model calling, data sending terminal cable interface module 6 and upper level acquisition station model calling.
Data receiver cable interface module 5 is connected with the normally closed contact of telecommunication cable transfer relay 3, and next stage acquisition station module is connected with the transfer contact of this group communication cable transfer relay 3 by communication cable line.
The data sending terminal cable interface module 6 of acquisition station module 1 is connected with the normally closed contact of telecommunication cable transfer relay 3, and upper level acquisition station module is connected with the transfer contact of this group communication cable transfer relay 3 by communication cable line.
The adjacent corresponding normally opened contact of two group communication cable transfer relays 3 is directly connected.
Telecommunication cable transfer relay 3 in every one-level acquisition station module is controlled by its upper level acquisition station module, and acquisition station module at the corresponding levels can only control the telecommunication cable transfer relay in next stage acquisition station module.
Two signal wires that described its control signal of telecommunication cable transfer relay 3 is all sent here by higher level's acquisition station module control.
The control signal of described telecommunication cable transfer relay, by capacitance, carries out multiplexing with other AC signal lines in transmission cable.
principle of work:
Under system normal condition, the data receiver cable interface module 5 of acquisition station module at the corresponding levels received by the communication cable line of next stage acquisition station module by the normally closed contact of i hilted broadsword (or multitool) double-throw telecommunication cable transfer relay, thus enables subordinate's acquisition station module that data are entered our station; Our station data are connected to the normally closed contact of ii signal communication cable transfer relay by its data sending terminal cable interface module 6, thus enable the corresponding levels and lower DBMS be sent to higher level's acquisition station module by ii relay, achieve midsequent data communication.
If certain acquisition station module break down and can not proper communication time, its upper end acquisition station module just cannot be got in touch with this station, also by this station, its all subordinate station volume datas cannot be sent to main frame.Now upper level acquisition station module will by newly-increased cable, adhesive order is sent to telecommunication cable transfer relay at the corresponding levels, thus the connection disconnected between acquisition station module at the corresponding levels and telecommunication cable, higher level's acquisition station module is striden across acquisition station module at the corresponding levels simultaneously, directly be connected with subordinate acquisition station module communication cable, realize, with the data communication of all subordinates acquisition station intermodule, reaching the fault-tolerant object of relay transmission.
The effect of newly-increased telecommunication cable transfer relay switches the telecommunication cable of fault collection station module, every one-level acquisition station module all will increase such switching and control.But must be come by higher level's acquisition station module the control of the telecommunication cable transfer relay of the corresponding levels, because, if acquisition station module at the corresponding levels breaks down, its failure mode is difficult to expect, is difficult to the switching completed again telecommunication cable transfer relay and controls when our station breaks down.And telecommunication cable transfer relay at the corresponding levels is when being controlled by higher level's acquisition station, the control signal switching telecommunication cable transfer relay at the corresponding levels just needs to be connected in higher level's acquisition station module by newly-increased cable.If do not have unnecessary cable in cable, then relay control signal line also can be undertaken multiplexing by adding block condenser with other AC signal lines.
In order to save cable core, all relays switched for telecommunication cable, (or delivering to next stage by acquisition station at the corresponding levels) two signal wires that its control signal is all sent here by higher level's acquisition station control.
In normal system operation, switching control telecommunication cable transfer relay itself does not need to power up, and therefore, newly-increased telecommunication cable transfer relay both can not increase system power consumption, also can not introduce extra electromagnetic interference (EMI).Just after certain acquisition station module breaks down, telecommunication cable transfer relay in the module of fault collection station just can be energized adhesive, and increases corresponding power consumption, and switches pilot relay after switching completes, system just normally works, so also therefore can not introduce interference.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; change can be expected easily or replace, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
