2nd, the invention provides a kind of brand-new pressure gauge date storage method, with it, central processing unit can be remembered
Record go into the well every time it is upper electric when Beijing time, each time power-on time of the data collected to go into the well every time of going into the well is used as title
Storage.When needing extraction/play back the data of certain collection of going into the well, it is only necessary to the testing time corresponding to selection.Solve with
Past pressure gauge is gone into the well the problem of will being programmed to it every time, and data storage is clear.So without right before going into the well every time
Pressure gauge is programmed, it is only necessary to one-time programming.
3rd, the present invention monitors pressure variety between two neighboring pressure acquisition time point by central processing unit in real time, if
When pressure oscillation is larger, then the higher worksheet of sample frequency is replaced with, if pressure oscillation is smaller, is replaced with sample frequency more
Low worksheet.That is, whether pressure gauge meeting automatic decision of the present invention needs to change sampling rate, then increase
Or reduce sample frequency, intellegent sampling is realized, so as to effectively increase the accuracy rate of test under conditions of low-power consumption is ensured.
Brief description of the drawings
Fig. 1 is the circuit structure diagram of power-supplying circuit.
In figure：U1- switch chips, U2- power supply chips, U3- clock chips.
Embodiment
The present invention is described further below in conjunction with accompanying drawing：
The present embodiment includes central processing unit, memory, battery and pressure sensor, and central processing unit is by pressure sensor
The pressure data collected is stored into memory, and battery is that central processing unit, memory and pressure sensor are powered, in addition to
Power-supplying circuit for the power supply of control pressure sensor.
Include switch chip U1, power supply chip U2 and clock chip U3 in power-supplying circuit, battery is above-mentioned three
Chip power supply.
Central processing unit is by the data line interface SDA on clock chip U3 and clock signal line interface SCL to clock core
After piece U3 carries out instruction transmission, clock chip U3 sends instructions to switch chip U1, and switch chip U1 receives clock chip U3
Instruction after, switch chip U1 enters "off" state, now, power supply chip U2 voltage stabilizings output, for pressure sensor power, in
When central processor is not to clock chip U3 send instructions, clock chip U3 no longer sends to switch chip U1 and instructed, switch chip
U1 is in "off" state, and now, described power-supplying circuit does not have voltage output, pressure sensor power-off.
Pressure gauge provided by the invention is controlled by setting power-supplying circuit to realize the switch of voltage, when there is voltage defeated
When going out, whole circuit is data acquisition state (i.e. working condition), and when Non voltage output, whole circuit is resting state.
The collection and dormancy of whole circuit are exactly realized, so as to reach the purpose of low-power consumption.The time of collection and dormancy can be according to work
Condition requirement is arbitrarily set, and is fully meet autonomous controllable.
As further technical scheme, the data storage capacity of described memory is not less than 2,000,000 groups.Data storage
The size of capacity directly determines the length of activity duration, and ensureing that enough memory capacity can be brought to test jobs can not estimate
The advantage of amount, the difficult miscellaneous well for much needing to test for a long time could be completed from former multiple operation trials, lifted to one
Secondary test jobs are with regard to achievable present situation.
In the present invention, the massive store of memory is realized by the memory combination of multi-disc dependable performance.Each
In memory, data reversely store, i.e., store, solve in the past successively to first memory from last a piece of memory
Data storage/playback caused by data random storage mode such as stops at all disadvantages without reason, accomplished data in order storage with
Sequential playback.
Storage mode is using the uninterrupted method for conveying data, before next group of data transmit, data transfer chip
The packet of upper one group of data can be sent to storage chip always, untill storage chip receives this data.Therefore, Large Copacity
Memory module effectively increases test jobs overall efficiency, maximum while ensure that the accuracy of data storage and playback
Limit improves the uniformity, continuity, reliability of data storage/playback.
The invention provides a kind of date storage method of the low-power consumption pressure bomb without overprogram, applied to upper
In the pressure gauge described in claim 1 or 2 stated, specific method is：Pressure gauge is programmed before going into the well for the first time, for the first time
When going into the well, simultaneously data storage is operated according to the worksheet of programming, when going into the well for the second time, central processing unit is recorded on second
Beijing time when electric, each time power-on time of the data collected to go into the well every time of going into the well stores as title.The present invention carries
Supplied a kind of brand-new pressure gauge date storage method, with it, central processing unit it is recordable go into the well every time it is upper electric when
Beijing time, power-on time of the data collected of going into the well for each time to go into the well every time be used as title storage.Need extraction/playback
During the data of certain collection of going into the well, it is only necessary to the testing time corresponding to selection.Solve conventional pressure gauge to go into the well every time all
The problem of being programmed to it, and data storage is clear.So without being programmed before going into the well every time to pressure gauge, only
Need one-time programming.In order to provide time standard in control circuit, it is necessary to set timing chip inside pressure gauge, go out
When being needed before factory with Beijing time school.
As further technical scheme, monitored in real time by central processing unit between two neighboring pressure acquisition time point
Pressure variety, if pressure variety exceeds default bound, worksheet is changed, and according to new worksheet collection simultaneously
Data storage, if pressure variety exceeds the upper limit, i.e., when pressure oscillation is larger, then the higher worksheet of sample frequency is replaced with,
If pressure variety is less than lower limit, i.e., when pressure oscillation is smaller, then it is replaced with the lower worksheet of sample frequency.Namely
Say, whether pressure gauge meeting automatic decision of the present invention needs to change sampling rate, then increases or reduce sample frequency, real
Intellegent sampling is showed.By this sample mode, pressure gauge can when down-hole pressure is without fluctuation using relatively low sample frequency, with
Power consumption is reduced, extends the usage time of battery.When down-hole pressure unusual fluctuations, increase sample frequency, more accurately to remember
Record pressure changing.When pressure anomaly fluctuation situation disappears, sample frequency can be reduced to conventional sense, so as to recover low work(
Consumption state.
