In response to the problems set forth in the background, in one embodiment, a voltammeter is provided, as shown in FIG. 1. The voltammeter comprises:
the input end of the selection switching module 10 is used for connecting the object to be tested 99;
a measuring system 20, an input end of the measuring system 20 is connected to a first output end of the selection switching module 10;

an energy storage and power supply module 40, an input end of the energy storage and power supply module 40 being connected to an output end of the voltage conversion module 30, and an output end of the energy storage and power supply module 40 being connected to a power supply end of the measurement system 20, and being configured to store the electric energy input by the voltage conversion module 30 and being further configured to supply power to the measurement system 20;
a controller 50, a control end of the controller 50 is connected to a controlled end of the selection switching module 10, a power supply end of the controller 50 is connected to an output end of the energy storage and power supply module 40, and the controller 50 is configured to send a first control instruction and a second control instruction to the selection switching module 10 according to a configured power-taking time period and a configured measurement time period;
the first control instruction is used to instruct the selection switching module 10 to switch on the connection between the measurement system 20 and the object to be measured 99 in the measurement time period, so that the measurement system 20 measures an electrical signal of the object to be measured 99, the electrical signal of the object to be measured includes a voltage, and the second control instruction is used to instruct the selection switching module 10 to switch on the connection between the voltage conversion module 30 and the object to be measured 99 in the measurement power-taking time period, so that the voltage conversion module 30 converts the voltage of the object to be measured 99 and inputs the converted voltage to the energy storage and power supply module 40.
The selection switching module 10 is used for selectively connecting the connection between the measurement system 20 and the object to be measured 99 or the connection between the voltage conversion module 30 and the object to be measured 99.
The electrical signal of the object to be measured 99 obtained by the measuring system 20 includes parameters such as voltage, current, phase and frequency of the object to be measured 99.
The energy storage power supply module 40 may be a battery, a super capacitor, or other circuits capable of storing electric energy.
The controller 50 may be a chip with data analysis, processing and control functions, such as a single chip microcomputer and an ARM.
Specifically, the controller 50 in the voltammeter may send a first control instruction to the selection switching module 10 according to the configured measurement time period, and the selection switching module 10 switches on the connection between the measurement system 20 and the object to be measured 99 according to the received first control instruction, at this time, the voltage of the object to be measured 99 is measured by the measurement system 20. The controller 50 may further send a second control instruction to the selection switching module 10 according to the configured power-taking time period, the selection switching module 10 switches on the connection between the voltage conversion module 30 and the object to be measured 99 according to the received second control instruction, at this time, the voltage conversion module 30 converts the voltage of the object to be measured 99 and inputs the converted voltage to the energy storage power supply module 40, so as to supply power to the components in the voltammetry meter including the measurement system 20 and the controller 50.
Therefore, the voltammeter can be selectively switched to the measurement system 20 by the switching module 10 in the measurement time period, so that the measurement system 20 can accurately measure the electrical signal of the measured object 99, and can also be selectively switched to the voltage conversion module 30 by the switching module 10 in the power taking time period after the measurement time period, and the energy storage power supply module 40 in the voltammeter is charged by the electrical signal of the measured object 99, so as to ensure the power supply requirement during the measurement of the voltammeter, the measurement system 20 and the voltage conversion module 30 do not operate simultaneously, the measurement accuracy is ensured, meanwhile, the condition that the measurement is suspended due to insufficient electric quantity in the use process of the voltammeter is avoided, and the measurement efficiency is ensured.
In one embodiment, a plurality of alternately arranged electricity taking time periods and measuring time periods are configured; the controller 50 is configured to alternately send a first control instruction and a second control instruction to the selection switching module 10 according to the configured power-taking time period and the configured measurement time period. The measurement system 20 and the voltage conversion module 30 operate alternately according to a plurality of configured alternately arranged power-taking time periods and measurement time periods. Through setting up the electric time quantum and the measuring time quantum of getting of a plurality of short periods, through this kind of alternative control, can avoid the problem that measurement efficiency is low because of getting electric time overlength and leading to further improve volt-ampere meter's measurement of efficiency.
In one embodiment, the time lengths of the power-taking time periods are the same, and the time lengths of the measurement time periods are the same, and the controller 50 is configured to periodically and alternately send the first control instruction and the second control instruction to the selection switching module 10 according to the configured power-taking time period and measurement time period. The measurement system 20 and the voltage conversion module 30 are alternately operated periodically. The power-taking time periods and the measurement time periods with the same length are configured, on one hand, the number of parameters of the configuration time periods acquired by the controller 50 is small, which is beneficial to improving the control efficiency of the controller, and on the other hand, the storage space for storing the configured power-taking time periods and the measurement time periods in the controller 50 can be saved.
In one embodiment, the controller 50 is further configured to obtain an output voltage of the energy storage and supply module 40, and if it is determined that the energy storage and supply module 40 is fully charged according to the output voltage of the energy storage and supply module 40, control the selection switching module 10 to maintain a state of connecting the object to be measured 99 with the measurement system 20, and stop the above control process of alternately switching between the power taking mode and the measurement mode.
In one embodiment, as shown in fig. 2, the controller 50 is configured to control the selection switching module 10 to switch on the measurement system 20 and the object to be measured 99 in the sampling time period according to the configured sampling time period, acquire the voltage of the object to be measured 99 from the measurement system 20, and send the first control instruction and the second control instruction to the selection switching module 10 according to the configured power-taking time period and the configured measurement time period when it is determined that the voltage of the object to be measured 99 is within the preset voltage range.
The preset voltage range refers to the voltage range of the object to be measured 99 which can ensure the power supply efficiency of the volt-ampere meter. When the voltage in the voltage range is input to the energy storage power supply module 40 through the voltage conversion module 30, the correspondingly configured power taking time period is maintained at a short level, for example, less than or equal to 0.5s, and therefore, in the whole measurement process of the voltammeter, the problem of low measurement efficiency of the voltammeter due to the overlong duration of a single power taking time period is solved.
The sampling time period is positioned before the measuring time period and the electricity taking time period. Considering that if the voltage of the object to be measured 99 is too low, the object to be measured 99 is powered, the charging efficiency is very low, and the power-powered time period enough to support the power supply requirement of the measurement system 20 is lengthened, on the basis, before the power-powered and measurement switching control is performed, the voltage of the object to be measured 99 is sampled in the sampling time period, and if the voltage is judged to be within the preset voltage range, the step S600 is performed, so that the working efficiency of the voltammeter using the control method can be ensured.
For example, for a voltammeter with a voltage channel having a range of 0V to 500V, the preset voltage range may be set to 50V to 500V, and if the voltage of the object to be measured 99 measured by the measurement system 20 in the sampling time period is within a range of 50V to 500V, the first control instruction and the second control instruction are sent to the selection switching module 10 according to the configured power-taking time period and the measurement time period. Considering the problem of power supply efficiency for supplying power to the energy storage power supply module 40, if the voltage of the object to be measured 99 is lower than 50V, the controller 50 does not send the first control instruction and the second control instruction to the mode selection module according to the configured power-taking time period and measurement time period, and only controls the selection switching module 10 to connect the measurement system 20 to the object to be measured 99, so as to measure the electrical signal of the object to be measured 99.
In one embodiment, the selection switching module 10 is a relay. The first output terminal of the relay is connected to the measurement system 20, the second output terminal of the relay is connected to the voltage conversion module 30, the controlled terminal of the relay is connected to the controller 50, and the input terminal of the relay is connected to the object to be measured 99. In the case where the controller 50 sends the first control instruction to the relay, the relay turns on the connection between the measurement system 20 and the object to be measured 99 according to the received first control instruction, and at this time, the voltage of the object to be measured 99 is measured by the measurement system 20. Under the condition that the controller 50 sends a second control instruction to the relay according to the configured power-taking time period, the relay switches on the connection between the voltage conversion module 30 and the object to be measured 99 according to the received second control instruction, at this time, the voltage conversion module 30 converts the voltage of the object to be measured 99 and inputs the converted voltage to the energy storage power supply module 40, so that power is supplied to a part of the voltammetry meter including the measurement system 20 and the controller 50.
In one embodiment, the voltage conversion module 30 includes: and the input end of the charging chip is connected with the second output end of the selection switching module 10, the output end of the charging chip is respectively connected with the input end of the energy storage power supply module 40, and the charging chip is used for converting the voltage of the object to be tested 99 and then inputting the converted voltage to the energy storage power supply module 40. In addition, the charging chip can also be used for performing charging management and charging control on the energy storage power supply module 40, detecting the running state of the energy storage power supply module 40 and ensuring the normal running of the energy storage power supply module 40.
In one embodiment, the voltage conversion module 30 further includes: and the input end of the flyback power supply is connected with the second output end of the selection switching module 10, the output end of the flyback power supply is connected with the input end of the charging chip, and the flyback power supply is used for reducing the voltage of the object to be measured 99 and then charging the energy storage power supply module 40 through the charging chip.
For example, alternating current input by the object to be tested 99 may be rectified and stepped down to 5V direct current to be output to the charging chip by the flyback power supply, for example, when the object to be tested 99 is a voltage transformer, and then the energy storage and power supply module 40 is charged by the charging chip.
In one embodiment, as shown in fig. 2, the voltammeter further includes: a communication module 60, a display module 70, and/or an input module 80; the controller 50 is connected to the communication module 60, the display module 70 and/or the input module 80; the communication module 60 is further used for connecting an upper computer, and the controller 50 is used for acquiring the voltage of the object to be measured 99 measured by the measuring system 20 and uploading the voltage to the upper computer; the controller 50 is further configured to obtain the voltage measured by the measurement system 20 and input the voltage to the display module 70 for display; the controller 50 receives the power-taking time period and the measurement time period input from the input module 80.
By arranging the communication module 60 in the voltammeter, the voltage of the measured object 99 acquired by the controller 50 from the measurement system 20 can be transmitted to an upper computer in real time by utilizing the communication function of the communication module 60, so that the upper computer can record and analyze the voltage of the measured object 99, the upper computer can be a computer in a control room, and the like, and the electric signal condition of the measured object 99 can be conveniently monitored by a worker in real time.
In addition, the input module 80 may be a device having an input function, such as a keyboard, and therefore, a user may flexibly set the power-taking time period and the measurement time period as needed through the input module 80, and may flexibly adjust according to the application scene change and the characteristic of the object to be measured 99, and the configuration flexibility is high.
In one embodiment, as shown in fig. 2, the voltammeter further includes: and the USB charging module 90, one end of which is connected with the energy storage power supply module 40, and the other end of which is connected with an external power supply, is used for supplying power to the energy storage power supply module 40 through the external power supply under the condition of no voltage signal of the object to be measured.
In one embodiment, as shown in fig. 3, there is provided a voltammeter control method, comprising:
and S200, setting a power taking time period and a measuring time period.
And S600, sending a first control instruction and a second control instruction to the selection switching module according to the measurement time period and the power taking time period.
The first control instruction is used for indicating the selection switching module to be connected with a measured system and a measured object in each measurement time period so that the measurement system can measure an electric signal of the measured object, the electric signal of the measured object comprises voltage, and the second control instruction is used for indicating the selection switching module to be connected with the voltage conversion module and the measured object in each power taking time period so that the voltage conversion module converts the voltage of the measured object and then transmits the converted voltage to the energy storage power supply module;
the input end of the selection switching module is used for connecting a measured object, the first output end of the selection switching module is connected with the input end of the measuring system, and the second output end of the selection switching module is connected with the input end of the voltage conversion module; the input end of the energy storage power supply module is connected with the output end of the voltage conversion module, and the output end of the energy storage power supply module is respectively connected with the power supply end of the measuring system and the power supply end of the controller and used for supplying power to the measuring system and the controller.
The specific limitations of the selection switching module, the measurement system, the energy storage and power supply module and the controller can be referred to the limitations of the voltammetry table above, and are not described herein again.
Specifically, after the power taking time period and the measuring time period are set, a first control instruction can be sent to the selection switching module according to the set measuring time period, the selection switching module only switches on connection between the measuring system and the measured object according to the received first control instruction, and at the moment, the voltage of the measured object is measured through the measuring system. And a second control instruction can be sent to the selection switching module according to the configured power taking time period, the selection switching module is connected with the voltage conversion module and the measured object according to the received second control instruction, and at the moment, the voltage conversion module converts the voltage of the measured object and inputs the converted voltage to the energy storage power supply module, so that power is supplied to a part of the voltammetry meter including the measurement system and the controller.
Therefore, by adopting the volt-ampere meter control method, the measurement system can be executed in the measurement time period, so that the voltage of the measured object can be accurately measured, the voltage conversion module can be executed in the power taking time period after the measurement time period, the volt-ampere meter is charged through the voltage signal of the measured object, the measurement system and the voltage conversion module do not operate simultaneously, the measurement accuracy is ensured, meanwhile, the condition that the measurement is suspended due to insufficient electric quantity in the use process of the volt-ampere meter is avoided, and the measurement efficiency is ensured.
In one embodiment, as shown in fig. 4, before the step of sending the first control instruction and the second control instruction to the selection switching module according to the measurement time period and the power-taking time period, the method further includes the steps of:
and S300, setting a sampling time period.
And S400, sending a third control instruction according to the sampling time period, and acquiring the voltage of the measured object measured by the measuring system in the sampling time period.

And the third control instruction is used for indicating the selective switching module to switch on the connection between the measuring system and the measured object in the sampling time period.
The preset voltage range refers to the voltage range of the measured object capable of ensuring the power supply efficiency of the volt-ampere meter. When the voltage in the voltage range is input to the energy storage power supply module through the voltage conversion module, the correspondingly configured power taking time period is maintained at a short level, for example, less than or equal to 0.5s, and therefore, the problem of low measurement efficiency of the voltammeter due to overlong duration of a single power taking time period in the whole measurement process of the voltammeter is solved.
The sampling time period is positioned before the measuring time period and the electricity taking time period. Considering that if the voltage of the measured object is too low, the measured object is taken, the charging efficiency is very low, and the power taking time period which is enough to support the power supply requirement of the measurement system is prolonged, on the basis, before the power taking and measurement switching control is carried out, the voltage of the measured object is sampled in the sampling time period, and if the voltage is judged to be within the preset voltage range, the step S600 is executed, so that the working efficiency of the volt-ampere meter using the control method can be ensured.
For example, for a voltammeter with a voltage channel having a range of 0V to 500V, the preset voltage range may be set to 50V to 500V, and if the voltage of the measured object measured in the resampling time period of the measurement system is within a range of 50V to 500V, the first control instruction and the second control instruction are sent to the selection switching module according to the configured power-taking time period and the measurement time period. Considering the problem of power supply efficiency of the energy storage power supply module, if the voltage of the measured object is lower than 50V, the controller does not send the first control instruction and the second control instruction to the mode selection module according to the configured power taking time period and the measurement time period, and only controls the selection switching module to switch on the connection between the measurement system and the measured object in the sampling time period through the electric control instruction to measure the voltage of the measured object.
In one embodiment, the step of setting the power-taking time period and the measurement time period includes:
and setting a plurality of alternately arranged electricity taking time periods and measuring time periods. As described in the above embodiment of the voltammeter, the first control instruction and the second control instruction are alternately sent to the selection switching module based on the alternately arranged power taking time periods and measurement time periods, so that the power taking process between two adjacent measurement processes can be ensured to be short in maintenance time, and the high-efficiency measurement is ensured while the power supply requirement during measurement can be maintained.
In one embodiment, the time lengths of the power-taking time periods are the same, and the time lengths of the measurement time periods are the same. As described in the embodiments of the voltammetry meters, by configuring the power-taking time periods with the same length and the measurement time periods with the same duration, on one hand, the number of parameters of the configuration time periods obtained by the controller is small, which is beneficial to improving the control efficiency of the controller, and on the other hand, the storage space for storing the configured power-taking time periods and the measurement time periods in the controller can be saved.
In one embodiment, the time length of the power-taking time period is the same as the time length of the measurement time period. By configuring the power taking time period and the measurement time period with the same length, the minimum quantity of parameters of the configuration time period acquired by the controller can be realized, the improvement of the control efficiency is facilitated, the stable operation of the control method is ensured, and in addition, the storage space for storing the configured power taking time period and the configured measurement time period in the controller can be minimized.
