For ease of understanding, a detailed flow of an embodiment of the present invention is described below, and referring to fig. 1, a first embodiment of a battery-powered temperature recording method according to an embodiment of the present invention includes:

s1, detecting the temperature of the deployment environment of the battery-powered temperature recording device through a sensor to obtain temperature data to be stored, and judging whether the temperature data to be stored is lower than a preset limit temperature through a controller;

in this embodiment, the sensor is a temperature sensor, which can detect the ambient temperature in real time, collect the ambient temperature at intervals to obtain ambient temperature data, and detect the ambient temperature in real time through the sensor in the battery-powered temperature recording device, that is, measure the ambient temperature through a commonly used thermocouple temperature sensor, when the working end of the thermocouple contacts the ambient temperature, there is a temperature difference with the temperature of the free end of the thermocouple, because the temperature difference at the two ends of the thermocouple can generate a thermal electromotive force in the loop, and the direction and magnitude of the thermal electromotive force are related to the material of the conductor and the temperatures of the two junctions, and further through a thermocouple graduation chart made by the functional relationship of the thermal electromotive force temperature, the thermocouple temperature sensor can calculate the measured ambient temperature data to obtain the temperature data to be stored.

The limit temperature is the environmental temperature of the battery in the temperature detection device, the output voltage and current of the battery are reduced when the temperature is lower than the critical temperature condition, so that the critical temperature condition of the whole device cannot be supported, the temperature data to be stored obtained by the temperature sensor is transmitted to the controller through the connecting circuit, a limit temperature value is preset in the controller, the transmitted temperature data to be stored is converted into a data type which can be processed by the controller, the controller compares the ratio of the temperature data to be stored and the limit temperature through a comparison function, and judges whether the temperature data value to be stored is lower than the limit temperature, namely, a digital-analog converter in the controller converts the temperature data transmitted as an analog signal by the sensor into a digital signal which can be identified and processed by the controller, and then the temperature data in the type of the digital signal is compared with the limit temperature value by calling the comparison function, the comparison of the two values can know whether the temperature data value currently input into the controller is lower than the limit temperature value.

S2, detecting the temperature of the deployment environment of the battery-powered temperature recording device through a sensor to obtain temperature data to be stored, and judging whether the temperature data to be stored is lower than a preset limit temperature through a controller;

in this embodiment, the first memory is a volatile memory, which is a random access memory (i.e., RAM) for temporarily storing programs and data in the controller for direct exchange and temporary storage, and can achieve read and write at any time, and has a high speed, the largest difference between the first memory and the nonvolatile memory is data volatility, that is, data stored in the nonvolatile memory is lost along with power failure, when the temperature data to be stored obtained by comparing the controller through a comparison function is lower than a limit temperature value, because the power supplied by a battery is not enough to provide normal operation of the whole temperature recording device, while the stored data in the nonvolatile memory is not easy to lose, the power consumed by the nonvolatile memory is almost half of that of the whole device, at this time, the operation of the nonvolatile memory is stopped first, and the volatile memory with lower power consumption is used to achieve temporary compression storage of the temperature data, thereby solving the storage of the temperature data at the limit temperature, the controller firstly judges the surplus degree of the memory array space, if the memory array space is not fully stored, the temperature data to be stored is stored in the memory array, if the memory array space is fully stored, the temperature data stored in the memory array is firstly compressed in a mean value calculation mode, and the temperature data obtained by compression and the temperature data to be stored are stored in the memory array.

In the practical application processing process, when the controller calls a comparison function to compare and obtain that the temperature data to be stored is lower than the limit temperature data value, the surplus degree of the memory array space is detected, the memory array identifies the used and called storage space in the volatile memory through the controller, the memory array space is established by identifying the storage space which is not used in the volatile memory, if the controller detects that the memory array space is not fully stored, the temperature data to be stored is stored in the memory array space, and if the memory array space is completely stored, the temperature data which are already stored in the memory array space are merged.

S3, detecting the power supply state of the battery in real time through the controller, and judging whether the power supply state meets the preset power supply condition;

in this embodiment, the power supply state refers to the operating state of the battery current and the battery voltage provided by the battery at this time, and the controller in the temperature recording device determines whether the power consumption of the nonvolatile memory that can normally store data is satisfied by detecting the power consumption of the battery provided to the nonvolatile memory at this time, and further determines whether the power consumption of the nonvolatile memory that can normally store data satisfies the normal operation of the entire device, so as to store the measured temperature data in the nonvolatile memory.

In practical application, when the battery provides voltage and current for the temperature recording device, the controller can detect the provided voltage and current of the battery in real time through the current detection circuit and the voltage detection circuit on the periphery of the controller, so that the controller can know the values of the voltage and the current provided by the battery in real time, and the current and the voltage values are compared with the voltage value and the current value required by the temperature recording device in a normal working state according to the values of the current and the voltage, so that whether the power supply state of the battery meets the condition of normal working operation of the whole temperature recording device at the moment can be obtained, and the recording function of storing the detected temperature data into the nonvolatile memory is realized.

And S4, if the power supply state meets the power supply condition, writing the compressed temperature data stored in the first memory into the second memory.

In this embodiment, the second storage is a nonvolatile storage, and can implement a long-term storage function of temperature data, if the controller detects that the battery power supply state satisfies the normal operation of the temperature recording device, and implements a recording function of storing the measured temperature data into the nonvolatile storage, it is determined whether temperature data is still stored in a memory array constructed by the volatile storage, if temperature data stored in a temporary compression mode is also stored, the temporary temperature data in the memory array is stored and written into the nonvolatile storage and the storage of the data is terminated, and if storage spaces in the memory array are all empty arrays, the operation of the program is terminated.

In practical application, through the judgment processing of a current and voltage monitoring circuit and a controller in the temperature recording device, if the voltage and the current provided by the battery meet the normal operation of the temperature recording device, whether the memory array space stores data is judged firstly, the controller traverses all the memory array spaces by accessing the first address of the memory array space constructed by the volatile memory, if the second address of the array memory is non-empty data, the traversal is continued until the array address of the empty data is found, and the empty data refers to a mark that the array space temporarily does not store the temperature data when the corresponding array memory space does not store the temperature data. When the empty data mark is judged, storing all the temperature data stored with temporary compressed storage in the front of the array into a nonvolatile memory, ending the program after the storage is finished, and if the second address of the array memory is empty data, indicating that the measured temperature data is stored into the nonvolatile memory, ending the operation of the program.

In this embodiment, after the sensor detects the temperature of the deployed environment, the measured temperature data to be stored is transmitted to the controller, the controller compares the temperature data with a preset limit temperature, if the temperature data is lower than the limit temperature value, the remaining degree of the current memory array space is determined, if the remaining degree is certain, the temperature data is directly stored into the memory array, if the memory array does not have the remaining storage space, the stored temperature data is compressed, and the compressed temperature data and the temperature data to be stored are stored into the volatile memory together.

And then judging whether the power supply of the current device is normal, if the power supply is abnormal, continuously acquiring and compressing the temperature data for temporary storage, and if the power supply is normal, storing the temperature data temporarily compressed and stored in the volatile memory into the nonvolatile memory to realize the storage of the temperature data. Based on the method, the working temperature of the device can be further reduced by using the method under the same battery power supply, the device can work under lower temperature, and the power for writing data into the storage module is equivalent to the total power consumption of the controller and the sensor under the general condition, so that when the temperature is lower than the limit temperature, the battery power supply pressure is halved, and when the device is below the limit temperature for a long time, the device can have longer working time, and the service life of the device is prolonged.

Referring to fig. 2, a second embodiment of the method for recording battery-powered temperature according to the embodiment of the present invention includes:

s11, if the temperature data to be stored is higher than the limit temperature, determining that the power supply of the battery power supply temperature recording device is normal, and judging whether the historical temperature data are stored in the first storage through the controller;

in the embodiment, the preset limit temperature is that the limit temperature value changes due to the fact that the power supply capacity of the battery is attenuated along with use, a corresponding temperature function is established through a comparison relation between the use process of the electric quantity obtained through actual measurement and the limit temperature, the temperature function is used as a preset limit temperature parameter, the controller judges and obtains a current limit temperature value, the controller in the temperature recording device compares the temperature data to be stored detected by the sensor with the limit temperature value, if the temperature data value to be stored is higher than the limit temperature value, the current limit temperature value can be known to be normal in power supply of the battery, and then the controller judges whether historical temperature data are stored in the volatile memory or not;

s12, if the historical temperature data are stored, storing the historical temperature data and the temperature data to be stored into a second memory through the controller;

in this embodiment, if the value of the temperature data to be stored is higher than the limit temperature value, it is known that the power supply of the battery is normal at that time, the temperature recording device may store the measured temperature data in the nonvolatile memory, and if the temperature data temporarily compressed and stored due to the temperature being lower than the limit temperature is stored in the volatile memory at that time, the controller extracts the data stored in the volatile memory and stores the data in the nonvolatile memory together with the temperature data to be stored at that time.

S13, if the historical temperature data are not stored, storing the temperature data to be stored into a second memory through the controller;

in this embodiment, if the temporarily compressed and stored temperature data is not stored in the volatile memory at this time, the temperature data to be stored this time is stored in the nonvolatile memory.

In practical application, the data measured by the sensor in the temperature recorder is converted to obtain temperature data to be stored, the temperature data to be stored is transmitted into the controller, the temperature data to be stored is further compared with a limit temperature value, the limit temperature can be-40 ℃ by taking the working limit temperature of a CR2450 battery as an example, if the temperature data to be stored is higher than-40 ℃, whether the volatile memory stores the temporarily compressed and stored temperature data generated by being lower than-40 ℃ is judged, the controller judges whether the volatile memory is empty data by accessing the 2 nd address of the volatile memory, if the volatile memory is non-empty data, the array space address of the memory array space built by the volatile memory is traversed through a traversal function, and when one is traversed to be empty data, the temperature data before the array space is empty data is extracted through traversal, and storing the extracted temperature data which is temporarily compressed and stored and the temperature data to be stored into a nonvolatile memory together, and if the controller is empty data for the 2 nd address which accesses the volatile memory, storing the temperature data to be stored into the nonvolatile memory without storing the temperature data which is temporarily compressed and stored in the volatile memory.

S2, if the temperature data to be stored is lower than the limit temperature, temporarily compressing the temperature data to be stored through a first memory and storing the temperature data;

In this embodiment, it is described in detail that the controller compares and determines temperature data to be stored with a preset limit temperature value, if the temperature data is higher than the limit temperature value, the power supply of the device is normal at this time, it is determined whether temporary compressed data is stored in the volatile memory at this time, if the temporary compressed data is present, the temperature data to be stored and the temporary compressed data are stored in the nonvolatile memory, and if the temporary compressed data is not present, the data to be stored is directly stored in the nonvolatile memory, so that the temperature data is stored. Compared with the prior art, the method can judge whether the current measured temperature is lower than the limit temperature or not, further judge whether the temporary compression volatile memory storage operation is required or not, realize the judgment before the device data storage operation under the limit low temperature, and is beneficial to preventing the device from resetting and realizing the temperature data storage under the condition of the limit low temperature.

Referring to fig. 3, a third embodiment of the method for recording battery-powered temperature according to the embodiment of the present invention includes:

s21, judging whether a memory array space corresponding to the temperature data to be stored has a residual storage space or not through the controller, wherein the first storage comprises at least one memory array space;

in this embodiment, after comparing the temperature data acquired by the sensor with the limit temperature data, if the temperature data to be stored is lower than the limit temperature, the controller determines the remaining degree of the memory array space formed by the volatile memory component.

S221, if the residual storage space exists, traversing the residual storage space through the controller to obtain sequential labels of the memory arrays in the residual storage space;

in this embodiment, the controller obtains, through traversal identification, that a storage space exists in the memory array space, and in the traversal process of the memory array space, the controller marks, from the beginning, data of the temperature data stored in traversal according to the arabic number, starting from 1, and traverses the data until the first empty data appears, and then stores the temperature data to be stored into the array space address corresponding to the empty data mark, thereby implementing the function of storing the data to be stored into the volatile memory.

S222, storing the temperature data to be stored to a first memory array sequentially marked in the residual storage space through the controller;

in this embodiment, if there is a remaining storage space in the memory array space, the temperature data to be stored is stored in the memory array space in the volatile memory, so as to implement storage of temporary temperature data generated by the limit low temperature by the volatile memory.

In practical application, a controller in the temperature recording device calls a comparison function to compare temperature data to be stored, which is acquired by a sensor and transmitted to the controller, with a limit temperature value, if the temperature data to be stored is lower than the limit temperature data, the controller judges the remaining degree of a memory array space constructed by a volatile memory, assuming that the temperature recording device only acquires temperature, the temperature data storage occupies 2Bytes, the memory array continuous whole block storage space occupies 52Bytes, namely, the memory array can store 25 groups of temperature data and one temperature quantity data, when the temperature data is not stored, the memory array space is empty data 0xFF, when the controller stores the first temperature data, the temperature data is stored into the 2 nd address of the memory array and covers the original empty data, the number of the first address recording data is changed into 1, and if the empty data are stored in the memory array space, indicating that a certain residual degree exists in the memory array space for storing the data, and further storing the temperature data to be stored in the memory array space in the nonvolatile memory.

S23, if the residual storage space does not exist, the controller extracts the stored temperature data in the memory array space;

in this embodiment, if there is no remaining storage space in the memory array space, the controller extracts the stored temperature data in the memory array space.

S24, calculating the average thermodynamic temperature of the extracted temperature data, and taking the thermodynamic average temperature as the mean value of the stored temperature data;

in this embodiment, the controller obtains that there is no remaining storage space in the memory array space through traversal identification, and compresses all temporary temperature data stored in the memory array space through a traversal function, that is, traverses all temporary temperature data in the memory array space from a first address one by one in a storage direction through the traversal function, and then calls a thermodynamic average temperature function, and calculates thermodynamic average temperature values of the traversed temporary temperature data to obtain an average value of the stored temperature data.

The actual processing process of the part of program in the controller, when the controller in the temperature recording device has no empty data by traversing the memory array space, namely, the memory array space has no residual storage space, all the temperature data stored in the memory array space are extracted by calling a traversal function, in the traversal process, the 2 nd address is marked as an Arabic numeral 1, the next traversal is a numeral plus one, all the temperature data and the number of the stored temperature data are obtained, further, a thermodynamic average temperature function is called, so that the average value of the stored temperature is obtained, in addition, if the current address is the average value of the first compression temperature data, the total number of the stored and collected temperature data is recorded, if the current address is not the average value of the first temperature data, the number collected at the current time is added with the number of the previously stored and collected temperature data, and outputting the number of the total temperature data and the obtained average value to further obtain the average value of the stored temperature data and the total number of the collected temperature data.

S25, clearing the stored temperature data in the memory array space, and storing the mean value and the temperature data to be stored in the memory array space through the controller;

in this embodiment, the stored temperature data in the memory array space is cleared, and the obtained average temperature data and the temperature data to be stored are stored in the memory array together, so that the temporary temperature data is compressed and stored by the nonvolatile memory.

In practical application, if non-empty data does not exist in the memory array space, it is indicated that the memory array space is full of temporarily compressed temperature data, the controller sums the temperature data in the memory array space through traversal and an averaging function, and then obtains an average value by dividing the sum by the number of the stored temperature data, so as to obtain the average temperature data of the temporarily compressed temperature data, then clears the temporarily compressed temperature data stored in the memory array space, all addresses are covered by the empty data, then obtains the average temperature data and the temperature data to be stored, and stores the two data into the first address and the 2 nd address of the cleared memory array space together, thereby realizing the function of compressing the temporary temperature data and storing the data into the volatile memory.

In this embodiment, on the basis of the second embodiment, when the controller determines that the temperature data to be stored is lower than the preset limit temperature, the remaining degree of the memory array space is further determined, if the memory array space has a remaining storage space, the temperature data is temporarily stored in the memory array, if the memory array is fully stored, the stored temperature data is extracted first, then the average thermodynamic temperature is calculated, the total number of the stored and acquired temperature data is recorded, the temperature data storage memory space is cleared, and finally the calculated average thermodynamic temperature, the temperature to be stored, and the acquired number are stored in the emptied memory array space, so that the temporary compressed storage of the temperature data at the limit temperature is realized. Compared with the prior art, the method can realize temporary storage of the data, and under the limited storage space, the average thermodynamic temperature of the fully stored temperature data is calculated, so that temporary compression storage of the data is realized, the continuous storage of the temperature data in the limited volatile storage space is realized, and the temperature data at the limit temperature is not lost.

Referring to fig. 4, a fourth embodiment of the method for recording battery-powered temperature according to the embodiment of the present invention includes:

s2501, judging whether the temperature data stored in the first storage meets preset temperature acquisition conditions or not through the controller;

in this embodiment, the preset temperature collecting condition is usually a design index of data collecting amount, for example, the index 15000 group, the collecting is not continued enough, and after the temperature data to be stored is collected and stored, the controller detects the stored temperature data to be stored, and detects whether the stored temperature data meets the preset temperature collecting condition or not.
