Description

Technical Field

[0001] This invention relates to the field of geophysical instrument technology, and in particular to a current detection device and a multi-mode endurance prediction method for geophysical instruments. Background Technology

[0002] In the field of geophysical exploration, it is often necessary to deploy exploration equipment in the target area for long-term data acquisition. To meet the practical needs of long-term continuous field operations, the built-in batteries of geophysical exploration equipment can last for tens of days or even months. To reduce average power consumption and improve battery life, many functional modules in geophysical instruments, except for the most critical data acquisition module, adopt a long-term sleep mode and short-term activation mode. For example, the GNSS module in geophysical exploration equipment is usually periodically woken up to acquire the second pulse signal and then enters sleep mode, remaining inactive for most of the time the equipment is operating. Simultaneously, in geophysical exploration equipment, apart from critical functions such as data acquisition, other functions can be enabled or disabled as needed; these are called optional functions, such as 4G communication, real-time data transmission, and Bluetooth status monitoring. Disabling optional functions also achieves the goal of reducing average power consumption and improving battery life.

[0003] While increased equipment battery life improves the effectiveness and convenience of long-term operations, it also brings significant challenges to battery life testing. Battery life is a crucial performance indicator for many geophysical exploration instruments; therefore, conducting battery life testing is essential and cannot be omitted during product development and testing. Currently, the widely used method in the industry is actual battery life testing, which involves assembling the finished geophysical equipment, fully charging it, and then testing the duration it can operate continuously before the battery is depleted.

[0004] However, due to the varying wake-up cycles and durations between different modules, the overall power consumption of the device exhibits significant time-varying characteristics. A fixed power consumption cannot be directly measured using simple instruments for calculating battery life. Furthermore, given the long battery life of the device, conducting actual battery life tests is too time-consuming, extending the device's R&D and testing cycle and hindering the implementation of more detailed power consumption measurements. Moreover, once adjustments are made to the device's functions, its battery life will change simultaneously. Previous battery life test results will no longer accurately reflect the battery life under the new functional combinations, potentially requiring retesting, which is time-consuming and labor-intensive. Summary of the Invention

[0005] Based on the technical problems existing in the background technology, this invention proposes a current detection device for geophysical instruments and a multi-mode endurance prediction method, which shortens the endurance testing time, to a certain extent shortens the equipment development cycle, and accelerates the product iteration speed.

[0039] The technical solution of the present invention will now be described in detail through specific embodiments. Many specific details are set forth in the following description to provide a thorough understanding of the invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] like Figures 1 to 4 As shown, the present invention proposes a current detection device for a geophysical instrument, comprising a geophysical surveying device 1 and a current detection device 2 for supplying power to the geophysical surveying device 1. The current detection device 2 includes a precision voltage divider resistor 21, a regulated power supply 22, and a power detection module 23. One end of the precision voltage divider resistor 21 is connected to the positive output terminal of the regulated power supply 22, and the other end is connected to the input terminal of the geophysical surveying device 1. The output terminal of the geophysical surveying device 1 is connected to the negative output terminal of the regulated power supply 22. The input terminal of the power detection module 23 is connected to the input terminal of the precision voltage divider resistor 21, and the output terminal is connected to a terminal. The current detection device 2 also includes a USB chip 24, with its two ends connected to the power detection module 23 and the terminal, respectively.

[0041] The current detection device 2 is connected to the external geophysical survey equipment 1 via a power cord, supplying power to the geophysical survey equipment 1. The external terminal (personal computer) of the current detection device 2 is connected via a USB cable. The current detection device 2 transmits power consumption data to the personal computer via USB, and the computer supplies power to the current detection device 2 via USB. The chip in the power detection module 23 is configured with data for the current detection device 2. The personal computer runs a data processing program responsible for data analysis and real-time display. The power detection module 23 can be an INA219 power detection module manufactured by Texas Instruments, and the USB chip 24 can be a CH341T USB chip manufactured by Nanjing Qinheng.

[0042] The precision voltage divider resistor 21 is a small-value precision resistor with negligible resistance. It is connected in series with the external geophysical survey equipment 1. The current flowing through it is consistent with that of the geophysical survey equipment 1. This current causes a voltage difference to be generated across the precision voltage divider resistor 21. The power detection module 23 obtains the voltage value of the precision voltage divider resistor 21.

[0043] The regulated power supply 22 supplies power to the precision voltage divider resistor 21 and the external geophysical survey equipment 1, ensuring a stable input voltage for the entire system and facilitating subsequent power calculations. Therefore, the power detection module 23 receives the voltage signal across the precision voltage divider resistor, amplifies it, and converts it into a digital signal. Based on the resistance value of the precision voltage divider resistor 21, the current value of the precision voltage divider resistor 21 is obtained. This current is used as the current value of the geophysical survey equipment 1. Based on this current value and the output voltage of the regulated power supply 22, the power consumption value of the geophysical survey equipment 1 and the precision voltage divider resistor 21 is calculated. Since the resistance of the precision voltage divider resistor 21 is a small-value precision resistor with negligible resistance, this power consumption value can be approximated as the power consumption of the geophysical survey equipment 1. This power consumption value is then output to the USB chip 24, which is responsible for data transmission between the current detection device 2 and the external personal computer.

[0044] The above-mentioned current detection device 2 is used to test the power supply of the geophysical survey equipment 1. During the endurance test, the instantaneous current of the geophysical survey equipment 1 under the current functional combination can be monitored in real time. After a relatively short measurement period, the average power consumption of the equipment under the current functional combination can be given. At the same time, by changing the on or off of the optional functions on the geophysical survey equipment 1, the power consumption of each module or function can be accurately calculated, which is used to measure the power consumption and value of that module or function.

[0045] like Figure 2 As shown, a current detection device for a geophysical instrument can be used to predict the endurance of geophysical exploration equipment. The specific endurance prediction process is as follows:

[0046] A multi-mode endurance prediction method for geophysical instruments includes the following steps:

[0047] S1: After enabling all selectable functions of the geophysical survey equipment 1, perform continuous current monitoring for a period of time to calculate the maximum power consumption and average power consumption value P of the geophysical survey equipment 1. max and minimum theoretical battery life BL min ;

[0048] After activating all selectable functions of the geophysical survey equipment 1, current monitoring is performed for a continuous period of time. The average power consumption of the geophysical survey equipment 1 and the precision voltage divider resistor 21 during this period is calculated and approximated as the maximum average power consumption P of the geophysical survey equipment 1. max ;

[0049] Based on the maximum power consumption and average power consumption value P max The minimum theoretical endurance BL of geophysical survey equipment 1 was calculated based on the equipment's battery capacity Cap. min .

[0050] BL min =Cap / P max

[0051] It should be noted that the average power consumption of the geophysical survey equipment 1 and the precision voltage divider resistor 21 is approximated as the average power consumption of the geophysical survey equipment 1. The reason for this approximation is that the resistance of the precision voltage divider resistor 21 is extremely small, and its power consumption is negligible relative to the geophysical survey equipment 1. In addition, the average power consumption of the geophysical survey equipment 1 remains basically unchanged when it is running stably.

[0052] S2: After turning off all selectable functions of geophysical survey equipment 1, perform current monitoring for a continuous period of time to calculate the minimum and average power consumption values ​​P of geophysical survey equipment 1. minAnd maximum theoretical battery life BL max ;

[0053] After disabling all selectable functions of the geophysical survey equipment 1, current monitoring was performed for a continuous period of time. The average power consumption of the geophysical survey equipment 1 and the precision voltage divider resistor 21 during this period was calculated and approximated as the minimum average power consumption value P of the geophysical survey equipment 1. min ;

[0054] Based on the minimum power consumption and average power consumption value P min The maximum theoretical endurance BL of the geophysical survey equipment 1 was calculated based on the equipment's battery capacity (Cap). max .

[0055] BL max =Cap / P min

[0056] S3: Alternately disable the optional functions of geophysical survey equipment 1, continuously monitor the current of geophysical survey equipment 1 for a period of time, and calculate the average power consumption increase P corresponding to each optional function. zj and the reduction in theoretical battery life BL zj Specifically, the steps include the following:

[0057] S31: Alternately disable the optional functions of geophysical survey equipment 1, continuously monitor the current of geophysical survey equipment 1 for a period of time, and calculate the average power consumption value P of geophysical survey equipment 1 when a certain optional function is disabled. g ;

[0058] S32: Based on the average power consumption value P when a certain optional function is disabled. g The theoretical battery life (BL) of Geophysical Survey Equipment 1 with a certain optional function turned off was calculated based on the equipment's battery capacity (Cap). g ;

[0059] S33: Based on the average power consumption value P (maximum power consumption). max The power consumption value P when a certain optional function is turned off. g The average power consumption increase P corresponding to this optional function is calculated. zj ;

[0060] S34: Based on the minimum theoretical battery life BL min And the theoretical battery life when a certain optional function is turned off (BL) g The theoretical reduction in battery life BL corresponding to this optional function was calculated. zj .

[0061] Through steps S31 to S34, the average power consumption increase P corresponding to a certain optional function can be obtained. zj And the theoretical reduction in battery life BL zj This facilitates the calculation of the average power consumption and theoretical battery life of devices under the currently available function groups.

[0062] S4: Based on the increase in average power consumption P zj and minimum power consumption average power consumption value P min The average power consumption P of geophysical survey equipment 1 under the current selectable function group was calculated. ry And theoretical battery life BL ry The optional function group is a combination of one or more optional functions. Specifically, it includes the following steps S41 to S43:

[0063] S41: Statistically analyze the currently available function groups that are activated on geophysical survey equipment 1, and obtain the average power consumption increase P for each available function in the current available function group. zj ;

[0064] S42: Calculate the average power consumption increase P corresponding to each optional function. zj Increase to minimum average power consumption value P min The average power consumption P of geophysical survey equipment 1 under the current selectable function group is obtained. ry ;

[0065] S43: Based on the average power consumption P of the devices under the current optional function group ry The theoretical endurance (BL) of Geophysical Survey Equipment 1 under the current optional function group is calculated based on the equipment's battery capacity (Cap). ry .

[0066] Based on steps S1 and S2, the longest and shortest power consumption and the corresponding theoretical battery life can be obtained. Based on steps S1 to S3, the average power consumption increase P corresponding to a specific optional function can be obtained. zj and the reduction in theoretical battery life BL zj Based on steps S1 to S4, the average power consumption P of the device under any selectable function group in any mode can be obtained. ry And theoretical battery life BL ry This means that multi-mode range prediction has been achieved.

[0067] The multi-mode battery life prediction method described above does not require a complete charge-discharge cycle; it only needs to sample for a period of time to obtain relatively accurate average power consumption data, significantly shortening the battery life testing time. Therefore, it can shorten the equipment development cycle and accelerate product iteration to some extent. By using the controlled variable method, the power consumption of each module or function can be accurately measured. This data can be used during the equipment design and development process to adjust modules or functions, achieving a balance between functionality and battery life. By enabling or disabling selectable functions and adjusting equipment parameters according to actual needs, the battery life of the equipment in the field can be precisely controlled, avoiding problems such as insufficient battery life utilization or unexpected battery depletion due to uncontrollable battery life.

[0068] It should be noted that the battery life and power consumption corresponding to steps S1 to S4 above are theoretical values. If you need to draw a comparison table between theoretical and actual values, you can test the actual values ​​in the following way, and then compare the measured values ​​in the same mode with the theoretical values ​​in the same mode to obtain the theoretical battery life comparison table for each mode.

[0069] When determining the endurance time under a certain function combination, the endurance time of the geophysical survey equipment 1 under the corresponding optional function group is the actual endurance time under that optional function group.

[0070] A method for determining the actual average power consumption under a certain functional combination: By continuously monitoring the current of the geophysical exploration equipment for a period of time, the average power consumption of the geophysical exploration equipment and the precision voltage divider resistor 21 during that period is calculated, and this average power consumption is approximated as the actual power consumption data of the geophysical exploration equipment 1 under the current functional combination. The reasons for this approximation include: the resistance value of the precision voltage divider resistor 21 is extremely small, and its power consumption is negligible relative to the geophysical exploration equipment 1; the average power consumption remains essentially constant during stable operation of the geophysical exploration equipment 1. Therefore, this geophysical instrument can accurately measure and monitor the instantaneous current and average power consumption under the current functional combination in real time, which can be used to estimate the equipment's runtime.

[0071] The calculation process for actual average power consumption:

[0072] W i =UI t (t i+1 -t i )

[0073]

[0074] Among them, t i+1 and t i These represent the two current sampling times, where U is the output voltage of the regulated power supply, and I... t Let time t i The sampling current value at that time, W iFor t i+1 and t i The power consumption of geophysical survey equipment 1 between time points, where T is the test time length, n is the total number of samples during the test time, and P is the actual average power consumption value.

[0075] Maximum power consumption and average power consumption P max Minimum power consumption and average power consumption value P min Power consumption value P when a certain optional function is turned off g The above formula is also used for calculation.

[0076] like Figure 3 As shown, the overall process for multi-mode battery life prediction is as follows: First, measure the average power consumption of the device under each measured function combination, and the corresponding actual average power consumption value. The measured function combinations include: all optional functions are enabled, all optional functions are disabled, only optional function 1 is disabled, only optional function 2 is disabled, ..., only optional function n is disabled. Here, n is the number of all optional functions of the geophysical survey equipment 1. Then, calculate the theoretical battery life of the device under each measured function combination. Based on the average power consumption of all optional functions enabled and the average power consumption of only disabling a specific optional function, calculate the average power consumption increase P brought by each optional function. zj Ultimately, by increasing the power consumption of each optional function in any combination of optional functions to the minimum average power consumption value P, min The above steps yield the theoretical average power consumption and theoretical battery life under the current function combination. Finally, based on the data obtained from the above steps, a table comparing the theoretical battery life of the device under any function combination is created to facilitate subsequent use of the test results.

[0077] like Figure 4 The image shows a template for a theoretical endurance time comparison table for a geophysical exploration device with three optional functions / modules, showing the theoretical endurance time for each mode. The first row is the column header, and each subsequent row represents a function combination mode. For a geophysical exploration device with n optional functions / modules, the theoretical endurance time comparison table for each mode should contain 2... n Row data.
