Secondly, the control method of oil-well realtime monitoring system, this control method mainly was divided into for three steps:
(1). by the fuel-displaced situation in the sensing system I detection well site;
(2). the cable network by the well site passes to SCM system II with information, is controlled, is handled by SCM system II;
(3). pass to the mobile base station through the information after the SCM system II processing by mobile GPRS network, issue internet Internet by the mobile base station again, received by remote detection monitoring system III at last.
Wherein, in above-mentioned steps (two), as follows with regard to the concrete control step of SCM system II:
At first, program begins, the SCM system initialization;
Then, connect network, pick up counting,, need to wait for 10 seconds read transducers for avoiding signal oscillating by real-time clock, so, read in a secondary data every 10 seconds from sensor, and deposit in the buffer memory of single-chip microcomputer inside;
Then, real-time clock judges whether to be half an hour, and system requirements sends a secondary data per half an hour, and carries out this step and can save communication flows;
At last, turn back to 10 seconds meter steps of real-time clock, circulation is from sensor readings.
Need to prove that around here in this step, after one section program is carried out, when circulating from sensor readings, still need wait for for 10 seconds, this is for fear of signal oscillating, and then continues performing a programme; And microprocessor selected 30 minutes to send a secondary data, mainly was to save communication flows, and transmission in per 10 minutes is once intensive excessively, certainly will cause too high communication cost; It is oversize again to send a blanking time in per 1 hour, real-time monitoring to oil well is unfavorable, just in case there is accident to take place, it is oversize that people obtain time of information, handles if having little time, cause immeasurable loss, consequence is serious, and is hardly imaginable, so, the reason of comprehensive all angles, we selected with 30 minutes is that a spaced points sends a secondary data.
At last, be the core place of most critical of the present invention, the control flow of monitoring programme (describe by its hardware components front among the remote detection monitoring system III, so, here just no longer repeat), as shown in Figure 7, the concrete detection monitoring step of described remote detection monitoring system III is as follows:
At first, program begins, system initialization;
Then, detect monitoring programme and be divided into three branches---time-triggered report, listens for network, transmitter status:
In time-triggered report, arrive the record in the staqtistical data base then, printing reports, the report of sending short messages, disposal data the specified a certain moment if judge whether to arrive the client by timer; If do not arrive, then return and continue timing in the time-triggered report; Wherein, just the moment of client's appointment is not fixed, and it can be 10 minutes, 20 minutes, 30 minutes or the like, according to client's demand set printing reports, the time of the report of sending short messages;
In listens for network, in fact, all monitoring no matter whether connect circuit always; Judged whether connection,, then opened new thread, then do not returned and continue to monitor if connection is arranged; Enter to carry out successively behind this new thread and read in data, judgment data, whether judgment data is legal, if legal then deposit database in, if illegal, then closes this thread;
In transmitter status, whether the work that detects earlier transmitter is normal, if data query time of advent regularly, and surpass two hours, then send short messages and printed report; If regularly data query does not reach the time, then return and continue in the transmitter status to detect.
In addition, emphasize again one be that the monitoring programme of remote detection monitoring system III is made up of three parts: database, backstage control program, WEB service; Wherein, database: after data are received from network, deposit it in database (seeing Fig. 8 and data dictionary) earlier by background monitor, database is responsible for the management of data, and its technology is very ripe, repeats no more here; WEB service: inform today during output when people's application that authority is arranged on the network, it can obtain data from database, tell the applicant with the form of html web page then.
