The above-ground scheduling center is in communication with the launch tower through a TCP/IP network communication protocol, and the launch tower is in communication with the underground video call device through wireless communication based on QOM modulating. The link device mainly comprises the above-ground scheduling center (2), the launch tower (1) and the video call terminal (3).

Description

The linked set of oil field well video calling

Technical field

The present invention relates to the linked set of oil field well video calling, belong to the communications field.

Background technology

Because the demand of the video communication system of the dense population areas such as the demand of oil field well video communication and city has larger difference, so existing more perfect wireless video communication system, for example Personal Handyphone System, GSM, CDMA etc., because cost is high, utilance is low and do not possess the reasons such as scheduling feature, can't generally adopt at oil field well, and indiscriminately imitate the advantage that existing civilian communication system can not have been given play to Personal Handyphone System fully fully, wasted a large amount of system resource.

Summary of the invention

Technical problem: for the demand of oil field well video communication, we have designed the linked set of the oil field well video calling of the radio communication based on the QOM modulation.Launching tower is communicated by letter with the downhole video verbal system and is adopted the radio communication based on the QOM modulation, and it is realized simply, transmitted power is little, supports the low-speed communication of down-hole verbal system.

Technical scheme: the linked set of oil field well video calling of the present invention mainly comprises 3 parts, that is: aboveground control centre, launching tower and video call terminal; Launching tower comprises message sink module, processing module, Executive Module, output unit and timing module; Aboveground control centre comprises the first message transmission module, the first input unit, Executive Module, mode selection module, computing module and timing module; Video call terminal comprises the second input unit, processing module, logic judgment module, the second output unit, timing module and mode selector; Wherein, the input of the output termination input unit of the first output unit, logic judgment module, mode selection module and the second output unit, output termination first input unit of output unit and the input of the second input unit.

In launching tower, the output termination processing module of input unit, the output of processing module connects respectively Executive Module, timing module, and the output of Executive Module connects respectively output unit and processing module, the input of the output termination timing module of message transmission module.

In aboveground control centre, the first input unit, Executive Module, mode selection module, energy process module, the first output unit sequentially are connected in series, the first output unit is connected with timing module is two-way, the output of the first input unit also is connected with the input of timing module, and the output of Executive Module, mode selection module also is connected with the input of the first input unit.In the downhole wireless verbal system, the second input unit, processing module, Executive Module, the second output unit sequentially are connected in series, the output of timing module connects respectively Executive Module, mode selector (3.6), and Executive Module is connected with mode selector is two-way.

Beneficial effect: adopt this device will change IP-based communication modes fully into by Circuit-switched video calling mode, can take full advantage of the communication capacity of oil field well Industrial Ethernet like this, reach the utilization of resources and maximize, in down-hole, utilize IP can greatly reduce the cost of equipment as the bearer network of video simultaneously.

Embodiment

As shown in Figure 1, the scheme of this method comprises that three parts form: control centre 2 to the method for the access of oil field well video and seamless link; Launching tower 1; Video call terminal 3.Wherein:

1, launching tower 1

For launching tower, after input unit 1.1 is received message, this message is sent to judge module 1.2, processing module 1.2 is responsible for checking the correctness of the message of receiving, be transmitted to Executive Module 1.3 for the message that can receive, Executive Module 1.3 needs the message sent to output unit 1.4 according to the message output received, upgrade the next message that can receive of processing module 1.2 simultaneously, after output unit 1.4 sends message, open the overtime clocking capability of timing module 1.5, timing time is the time that next message expectation arrives, if receive correct message by processing module 1.2 at the appointed time, processing module 1.2 will be closed the overtime clocking capability of timing module 1.5 so, if what at the appointed time clocking internal module 1.5 was not received judge module 1.2 closes the timing instruction, it will initiatively allow processing module 1.2 upgrade the message that can receive next time so.

2, aboveground control centre 2

For this method, aboveground control centre 2 is cores.The initiation of system call and final completing all and must completing by this module of dispatching.For control centre, if downhole wireless verbal systems 3 are called out by control centre 2, (2 send messages related to calls, open subsequently timeout feature and, in the message sink state, wait for the reply of video call terminal 3 in control centre.If input unit 2.2 is received reply message, this message is sent to timing module 2.6, by timing module 2.6, judge whether overtime.If overtime, this message is sent to output unit 2.1, by 2.1 time-out errors of output unit.If it is not overtime, close timing module 2.6, this message is sent to Executive Module 2.3 simultaneously, Executive Module 2.3 judges whether according to the message received the message that I need, if it is send out message to mode selection module 2.4, otherwise send out the logic state error message to sending message module 2.1, continue to wait for receipt message by input unit 2.2 simultaneously.Mode selection module 2.4 judges whether to meet works as precondition, if send out message to computing module 2.5, upgrades current state concurrent message to output unit 2.1 simultaneously, enters next Messages-Waiting, opens timing module 2.6 simultaneously.Otherwise clockwork spring part error message is given and sent message module 2.1, continue to wait for receipt message by input unit 2.2 simultaneously.

If video call terminal 3 call scheduling centers 2, input unit 2.2 receives information and sending to Executive Module 2.3, judges whether to meet current state, if meet, sends message to mode selection module 2.4.Otherwise send the logic state error message to sending message module 2.1, continue to wait for receipt message by input unit 2.2 simultaneously.Mode selection module 2.4 judges whether to meet works as precondition, if send out message to computing module, upgrades current state concurrent message to output unit 2.1 simultaneously, enters next Messages-Waiting, opens timing module 2.6 simultaneously.Otherwise clockwork spring part error message is given and sent message module 2.1, continue to wait for receipt message by input unit 2.2 simultaneously.

3, the down-hole verbal system 3

For down-hole verbal system 3, after input unit 3.1 is received message, this message is sent to processing module 3.2, processing module 3.2 is responsible for checking the correctness of the message of receiving, be transmitted to Executive Module 3.3 for the message that can receive, Executive Module 3.3 is according to the state of the mode selector 3.6 of the message received and verbal system, output needs the message sent to output unit 3.4, upgrade the next message that can receive of logic judgment module 3.3 simultaneously, after output unit 3.4 sends message, open timing module (3.5 overtime clocking capabilitys, timing time is the time that next message expectation arrives, if receive correct message by Executive Module 3.3 at the appointed time, Executive Module 3.3 will be closed the overtime clocking capability of timing module 3.5 so, upgrade mode selector 3.6 simultaneously, if what at the appointed time clocking internal module 3.5 was not received Executive Module 3.3 closes the timing instruction, timing module 3.5 is by replacement mode selector 3.6 so.
