Also there are many data processing techniques in the prior art, but it respectively has advantage and disadvantage, briefly enumerates and is described as follows：
1, Microsoft Windows Communication Foundation (WCF)
This technology can meet the requirement of real-time Communication for Power, but user need to design and test suitable network topology structure.And
And this technology cannot be satisfied the requirement for supporting more equipment.WCF only supports the windows platform of prepackage .NET, can not support sector
Divide non-Windows platform device（Such as iOS device）.
And the technology is not perfect to the support of data sharing.Main cause is that the technology requires the preset data of collaborative share
Definition（Such as XML Scheme or data definition API）, so that shared both sides can parse shared data.The requirement leads to following two
Kind limitation：1）When certain equipment updates the data definition, the equipment of remaining access system must also redefine corresponding data lattice
Formula；2）For unknown new equipment, user's Chang Wufa preliminary setting data formats.In industrial applications, emergence
New equipment make investor must constantly upgrade-system to cope with new demand, consequence is then that system upgrade is cumbersome of a high price.
2, high-performance relational database

Step 1：RDS clients are locally generated data cell（Variable）Description information, including：Title, type,
Value；
Step 2：The description information of step 1 is sent to RDS servers by RDS clients with signal packet mode；
Step 3：RDS servers read description information, and whether inquire in server memory database has the data.As nothing should
Data cell, RDS servers create data in memory database；
Step 4：RDS servers preserve the data in memory database；
Step 5：RDS servers send a control signal to RDS clients with signal packet mode, inform operating result.
（Two）RDS server push data update is to related RDS clients
After push update only occurs in and writes data.
Step 6：RDS servers query subscription data cell in memory database（Variable）Client mesh
Record.The data cell is provided by RDS clients in step 1；
Step 7a：If inquired one or more clients in step 6, RDS servers are locally generated data cell
（Variable）Description information, including：Title, type, value.And this data cell is sent to signal packet mode in step 6
Inquire obtained all clients；
Step 7b：If do not inquired any client in step 6, RDS servers terminate this task.
（Three）RDS client subscription data
Step 1：One or more data cells that needs are subscribed to（Variable）, RDS clients are being locally it
Generate data cell one by one（Variable）Description information, including title；
Step 2：Several descriptions generated in step 1 are formed list by RDS clients, and are encapsulated as the data that pull subscription
Packet；
Step 3：Data packet in step 3 is sent to RDS servers by RDS clients with signal packet mode；
Step 4：RDS server read data packets are changed in memory database and preserve RDS clients and data cell
Subscribing relationship；
Step 5：RDS servers send a control signal to RDS clients with signal packet mode, inform operating result.
（Four）RDS clients actively read data
Step 1：RDS clients are locally generated data cell（Variable）Description information only includes title；
Step 2：The description information of step 1 is sent to RDS servers by RDS clients with signal packet mode；
Step 3a：RDS servers read description information, whether have the data in audit memory database.Such as without the data
Unit, RDS servers are with the control signal of signal packet mode transmission representative " unknown data " to client；
Step 3b：RDS servers read description information, whether have the data in audit memory database.As there are the numbers
According to unit, RDS servers read data value, and data value is sent to client with signal packet mode.
In DRILLING APPLICATION, accurate online state helps to improve safe handling of the operating personnel to equipment.For example,
In drilling process, pressure sensor may be offline and causes system senses pressure unchanged, and this situation needs notice behaviour in time
Make the personnel offline failure to avoid blowout caused by hypertonia.Therefore, the invention also includes RDS clients with fixed intervals
Heartbeat signal is sent to detect online situation.It is as follows：
Step 1：RDS clients send Heartbeat with signal packet mode and control signal to RDS servers；
Step 2：It whether there is the client-side information in RDS server audit memory databases；
Step 3a：According to step 2 result.The client-side information is such as inquired, RDS servers are sent with signal packet mode and controlled
Signal response processed；
Step 3b：According to step 2 as a result, such as failing to inquire the client, RDS servers send phase with signal packet mode
Signal should be controlled to client terminal start-up RDS client identity identification steps；
If step 1 time-out does not start, RDS servers assume that client connection disconnects.
As after step 1, RDS client timeouts do not receive the response signal of server, and RDS clients it will be assumed and take
Business device connection disconnects.
Either case in the off-line of RDS client timeouts or client malfunction with server in identification procedure
When, RDS servers, which may require that, re-recognizes RDS clients.
The above-mentioned each process steps interacted with RDS clients to RDS servers are illustrated, during these,
Respective change can occur for the connection status of RDS servers and RDS clients, and the variation of these states is that basis is presently in state
It is realized with RDS control signals；By the transformation of connection status, RDS servers and RDS clients can be appreciated that partner state information,
Such as RDS client states（As online or offline）, RDS servers and RDS clients current connection state, the network state etc.,
Facilitate RDS servers to flow control.For example, when RDS client off-lines, RDS servers will not push to latest data
The client, to save system resource and Internet resources.
To ensure that long-time steady operation, RDS servers need to coordinate connection status with RDS clients.It is shown in Fig. 3 to be
The connection status of RDS servers and a RDS client is how to be converted according to current state and control signal.Number in circle
