The specific embodiment
As Fig. 1~shown in Figure 8.A kind of oil well lowering-in operation data recording instrument is characterized in that being made up of master instrument, plug-in display and upper PC.Whole device is a controller with the single-chip microcomputer, adopts many cpu modes.In master instrument, the C8051F020 single-chip microcomputer is a controller, forms referring to master instrument structure shown in Figure 2.C8051F020 receives 6 road analog sensor signals, receives No. 2 photoelectric encoder signals by LPT by A/D timesharing in the sheet, can finish the stretching power of oil pipe in the lowering-in operation, dynamically lifting force, dynamically push power, static lifting force, water injection pressure, water filling temperature, pipe distance, pipe speed, the collection of nine parameters such as slippage relatively down down; Deposit the I of expansion after the survey data analyzing and processing in by the SMBus universal serial bus 2In the C storage chip, and liquor charging crystal display and the demonstration of plug-in display simultaneously.Single-chip microcomputer was gathered a secondary data every 1 second, every 5 seconds storage one secondary data.8 push button signallings then are sent to controller by LPT.
After the end of job, by communication cable notebook computer is linked to each other with this device, by software control, survey data dumps in the computer and preserves, and further analyzing and processing.
Because plug-in display has certain distance with the photoelectric encoder and the master instrument that are installed in the scene, be to guarantee the signal reliable transmission, all adopt long line transmission means, control by single-chip microcomputer separately in the receiving circuit.
Figure 3 shows that photoelectric encoder receiving circuit block diagram, selected the RS-422 interface mode for use, the three-phase pulse signal of two-way incremental photoelectric encoder, after the conversion of SN55182 level shifting circuit, be responsible for reception by 89C2051 (reception) single-chip microcomputer, be responsible for handling and regularly send to master controller C8051F020 by 89C2051 (processing) single-chip microcomputer.Side circuit is seen Fig. 7.
Fig. 4 is plug-in display circuit block diagram, and plug-in display receives display command and the data of master controller C8051F020 by the RS-485 interface mode.Receive and display driver by the 89C51 Single-chip Controlling.Plug-in display has two row totally 14 displaying blocks, and wherein the physical circuit of a demonstration is seen Fig. 8.
The analog quantity parameter that this device detects has 6, after sensor and measuring circuit conversion, utilizes 12 A/D of C8051F020 single-chip microcomputer inside to carry out mould/number conversion.The analog signal of input is 4~20 milliamperes of current signals, converts 0~2.4V voltage signal to through potentiometer, and this signal does not directly enter single-chip microcomputer and handles, but earlier through the isolated amplifier of a 1:1, inserts the A/D conversion links of single-chip microcomputer again.Because the feedback resistance of this amplifier is very high, has limited the front end input current.In the time of can preventing that the two-wire system sensor from breaking down, to the damage of single-chip microcomputer.Physical circuit is seen Fig. 9.
Whether transfinite in order to make single-chip microcomputer grasp measuring-signal, to import 4~20 milliamperes of current signals, corresponding potentiometer output 0~2.4V voltage signal, be adjusted into 0~21 milliampere of current signal, corresponding potentiometer output 0~2.4V voltage signal, device has diagnostic function to the abnormal operating state (sensor output is beyond 4~20 milliamperes of normal ranges) of sensor, and can report to the police by the LCD prompting.
In nine measurement parameters that require, except that water filling temperature and water injection pressure are the direct measuring amount, all the other are indirect measuring amount.Need combine with the working rig structure, sensor mount scheme and measuring method reasonable in design are carried out relevant calculating, could obtain relevant parameter.Below the pipe distance is measured as example with relative slippage, as shown in Figure 5.The driving wheel of following tube injection head drives oil pipe and moves down, and the photoelectric encoder 2 coaxial with driving wheel rotates synchronously; 1 of photoelectric encoder is coaxial with driven pulley, and when pushing oil pipe in the past oil well of working rig, mobile oil pipe drives photoelectric encoder 1 and rotates, and the umber of pulse of being exported by photoelectric encoder 1 can obtain the distance that oil pipe moves indirectly; Can judge by the umber of pulse value difference of two photoelectric encoder outputs whether the driving wheel of tube injection head skids down.
Owing to when the pipe machine is worked down, manage and put forward two kinds of situations of pipe under having, so the output signal of photoelectric encoder is needed sensing.Utilize LPT received code device output A, the level signal of B two-phase pulse, and with A, the level signal of B two-phase pulse coding.Referring to encoder output A, B two-phase pulse sequential chart shown in Figure 6.A pulse period is divided into four parts: t1~t4, four kinds of states that read are as shown in table 1:
t1 t2 t3 t4
Just change 00 10 11 01
Counter-rotating 01 11 10 00
Table 1 encoder output state
According to the state that collects for adjacent twice relatively, can differentiate the rotation direction of encoder immediately.
The course of work of this device is as follows:
After the opening power, liquid crystal display displays initial interface and operation indicating.The operating personnel only needs to operate with prompting as required.Usually operating personnel have two kinds of selections: initiating task or data communication.As after pressing " startup " button, operation begins.LCD begins dynamically to show the value of each job parameter, and the result all keeps a decimal.Need to show owing to have nine parameters, can arbitrarily switch demonstration by " main screen ", " secondary screen " button.
Can press " time-out " button Suspend Job as required in the whole operation process, then resume operation by " time-out " button once more.
The end of job can stop operation by " stopping " button.Also can carry out data communication by " communication " key and host computer this moment.If occur abnormal conditions such as " deadlocks " in the operation process, can make system recover normal operating conditions by " resetting " key.After resetting, further operation indicating appears in the display frame meeting, both can select to restart operation by "start" button, and the operation before can selecting to continue to reset by " implying " key again also can be uploaded data by " communication " key.
Transmit data as need and host computer, must before communication, connect connection, and " oil pipe job parameter acquisition system " software of host computer is ready to, set up good new database, write down the operational circumstances of this subjob, wait for that instrument begins communication, the time of each communication is generally very short.Administrative staff can utilize " oil pipe job parameter acquisition system " application software to carry out data management and analytical work.After all working finished, power cutoff got final product.
Plug-in instrument is on-the-spot plug-in Displaying Meter, connect with the master instrument interface after, directly be controlled by master instrument, do not need any autonomous operation.After operation began, plug-in display begins to show this instrument automatically, and it showed " pipe distance down " and " following pipe speed " two parameters synchronously.
