[0022] Embodiment one: this embodiment carries out temperature control detection on automobile sensor according to the data acquisition basis of Internet of Things, in order to ensure the running efficiency of automobile sensor, please refer to Figure 1As shown, the automobile sensor temperature control detection system based on Internet of Things technology comprises a temperature control detection platform, wherein the temperature control detection platform is communicatively connected with a sub-position evaluation analysis unit, a temperature control detection analysis unit and a temperature influence analysis unit; The temperature control detection platform generates a sub-position evaluation analysis signal and sends the sub-position evaluation analysis signal to the sub-position evaluation analysis unit. After receiving the sub-position evaluation analysis signal, the sub-position evaluation analysis unit evaluates and analyzes the automobile sensors at different positions, infers the importance of the sensors at each position to the automobile detection according to the sensor evaluation set for each position of the automobile, and can also infer the different influences of temperature on each sensor according to the operation evaluation analysis, so as to accurately perform temperature control detection; The automobile position to be subjected to temperature control detection is marked as a temperature control area, the sensors distributed and arranged in the temperature control area are acquired, and the positions of each sensor are marked as detection positions. The maximum numerical deviation value of the same detection parameter at the detection position in the temperature control area under different running durations of the automobile during operation is acquired, the floating amount of the numerical deviation of the same detection parameter at the detection position corresponding to the detection parameter under different environmental temperatures in the temperature control area is acquired, and the maximum numerical deviation value of the same detection parameter at the detection position in the temperature control area under different running durations of the automobile during operation and the floating amount of the numerical deviation of the same detection parameter at the detection position corresponding to the detection parameter under different environmental temperatures in the temperature control area are respectively marked as SPC and PCF; The overlapping duration of the cumulative period in which any detection parameter at the detection position in the temperature control area is not within the set parameter threshold and the automobile operation and maintenance period during the operation of the automobile is acquired, and the overlapping duration of the cumulative period in which any detection parameter at the detection position in the temperature control area is not within the set parameter threshold and the automobile operation and maintenance period during the operation of the automobile is marked as CDS; The above collected parameters are uniformly marked as sub-position evaluation analysis information, and the evaluation analysis coefficient XS of the sensor at the detection position in the automobile temperature control area is obtained by substituting the parameters into a formula, and the formula is: wherein bhg1, bhg2 and bhg3 are respectively the preset proportion coefficients of the maximum numerical deviation value of the same detection parameter at the detection position, the floating amount of the numerical deviation of the same detection parameter at the detection position, and the overlapping duration of the cumulative period, which are used for de-dimensioning processing of the collected parameters; The evaluation analysis coefficient XS of the sensor at the detection position in the automobile temperature control area is compared with the evaluation analysis coefficient threshold value: If the evaluation analysis coefficient XS of the sensor at the detection position in the automobile temperature control area exceeds the evaluation analysis coefficient threshold value, it is determined that the sensor at the corresponding detection position in the automobile temperature control area is abnormally evaluated and analyzed, and the corresponding sensor is marked as an important high-impact end; If the evaluation and analysis coefficient XS of the sensor corresponding to the detection position in the vehicle temperature control area does not exceed the evaluation and analysis coefficient threshold, it is determined that the evaluation and analysis of the sensor at the corresponding detection position in the vehicle temperature control area is normal, and the corresponding sensor is marked as a non-important low-impact end; After each detection position is divided into two types, the corresponding type is sent to the temperature control detection platform, and a temperature control detection analysis signal is generated and sent to the temperature control detection analysis unit. After receiving the temperature control detection analysis signal, the temperature control detection analysis unit performs temperature control detection and analysis on different types of sensors, and infers the operating efficiency of the sensors at the detection positions in the current vehicle temperature control area through ambient temperature analysis, thereby avoiding sensor detection deviations caused by inefficient temperature control. This can help improve the efficiency of vehicle operation detection, ensure the detection and operation stability of sensors in various parts, and further enhance the stability of vehicle operation detection. The temperature value exceeding the set temperature range threshold in the temperature control area is obtained, and the corresponding temperature is marked as the temperature value to be controlled. The peak value of the real-time temperature value to be controlled in the temperature control area during vehicle operation is collected. At the same time, the deviation floating frequency of the actual time taken to control the real-time temperature value to be controlled to be within the set temperature range during the continuous increase of the peak value and the set time consumption is obtained. The peak value of the real-time temperature value to be controlled in the temperature control area during vehicle operation and the deviation floating frequency of the actual time taken to control the real-time temperature value to be controlled to be within the set temperature range during the continuous increase of the peak value and the set time consumption are marked as temperature rise parameters and temperature control parameters, respectively, and compared with the peak value continuous increase span value threshold and the time consumption deviation floating frequency threshold, respectively: If the peak value of the real-time temperature to be controlled in the temperature control area during vehicle operation continues to increase and the span value exceeds the peak value continuous increase span value threshold, or the deviation floating frequency between the actual time taken to control the real-time temperature to be controlled to the set temperature range and the set time taken during the continuous increase of the peak value exceeds the time deviation floating frequency threshold, then the operating temperature environment of the current temperature control area is set to a high-intensity temperature environment; If the peak value of the real-time temperature value to be controlled in the temperature control area continuously increases within the set temperature range during vehicle operation, and the deviation floating frequency between the actual time taken to control the real-time temperature value to be controlled within the set temperature range and the set time taken during the continuous increase of the peak value does not exceed the time deviation floating frequency threshold, then the operating temperature environment of the current temperature control area is set to a low-intensity temperature environment; The adjacent floating interval time length shortening frequency of the detection parameter of the important high-influence end in the temperature control area in the current automobile running process is obtained, and the maximum span peak value of the corresponding numerical value floating of the adjacent detection time of the detection parameter of the unimportant low-influence end in the temperature control area is obtained, and the adjacent floating interval time length shortening frequency of the detection parameter of the important high-influence end in the temperature control area in the current automobile running process and the maximum span peak value of the corresponding numerical value floating of the adjacent detection time of the detection parameter of the unimportant low-influence end in the temperature control area are marked as high-influence information and low-influence information respectively, and are compared with the shortening frequency threshold and the maximum span peak value threshold respectively: If the adjacent floating interval time length shortening frequency of the detection parameter of the important high-influence end in the temperature control area in the current automobile running process exceeds the shortening frequency threshold, or the maximum span peak value of the corresponding numerical value floating of the adjacent detection time of the detection parameter of the unimportant low-influence end in the temperature control area exceeds the maximum span peak value threshold, it is judged that the current temperature control detection analysis is abnormal, if the current temperature environment is a high-intensity temperature environment, an environment alarm signal is generated and sent to the temperature control detection platform, after the temperature control detection platform receives the environment alarm signal, the sensor at the current detection position is controlled in the environment temperature, and if necessary, the automobile running period is regulated; if the current temperature environment is a low-intensity temperature environment, a device alarm signal is generated and sent to the temperature control detection platform, after the temperature control detection platform receives the device alarm signal, the sensor at the current detection position is detected in the device itself performance, and is put into detection use after detection qualification; If the adjacent floating interval time length shortening frequency of the detection parameter of the important high-influence end in the temperature control area in the current automobile running process does not exceed the shortening frequency threshold, and the maximum span peak value of the corresponding numerical value floating of the adjacent detection time of the detection parameter of the unimportant low-influence end in the temperature control area does not exceed the maximum span peak value threshold, it is judged that the current temperature control detection analysis is normal, if the current temperature environment is a high-intensity temperature environment, a safety signal is generated and sent to the temperature control detection platform; if the current temperature environment is a low-intensity temperature environment, a warning signal is generated and sent to the temperature control detection platform, after the temperature control detection platform receives the warning signal, the temperature environment control of the temperature control area is carried out for warning, according to the real-time temperature floating trend combined with the temperature control efficiency floating trend, the real-time analysis result is analyzed according to the real-time analysis result, and the corresponding environment control is carried out; After the temperature control detection platform completes the temperature control detection analysis control and receives the safety signal, a temperature influence analysis signal is generated and sent to a temperature influence analysis unit. After the temperature influence analysis unit receives the temperature influence analysis signal, temperature influence analysis is performed on the temperature control detection process of the temperature control area to determine whether there is temperature influence on the sensor in the current temperature control detection stage, thereby avoiding affecting the real-time detection efficiency of the sensor during the current cumulative running period detection, causing inaccurate detection of the temperature control area, and at the same time, the temperature influence analysis can detect the running efficiency of the sensor in real time and monitor the influence of temperature on the sensor in real time, which is beneficial to the running detection efficiency of the sensor; The temperature control detection period of the temperature control area is analyzed, and a period with the same length as the temperature control detection period is collected as a rear period and marked as a front period; the temperature control area influence analysis period is constructed by the two periods; and the detection parameter value of any detection position of the temperature control area is taken as the influence analysis reference parameter; The influence analysis reference parameter floating trend of the same detection position corresponding to the front period and the rear period is obtained, and the two floating trends are compared. If the influence analysis reference parameter floating trend of the front period and the influence analysis reference parameter floating trend of the rear period are connected trends, the temperature influence of the current temperature control area is normal, a temperature influence normal signal is generated and sent to the temperature control detection platform, and the temperature control detection platform continues to perform the current temperature control detection; The connected trend is that the two trends are in the same trend, and the growth trend or the decreasing trend corresponds to the floating span in the same range, which also includes that the two trends are in the same trend floating period, and the floating peak value and the valley value of the two trends are in the set range in the reciprocating floating period, and the floating span is also in the same range. Both cases belong to the connected trend; If the influence analysis reference parameter floating trend of the front period and the influence analysis reference parameter floating trend of the rear period are non-connected trends, the temperature influence of the front period of the current temperature control area is abnormal, the temperature control detection of the current temperature control area is suspended, the current automobile operation is controlled, and the real-time temperature environment of the temperature control area is detected and regulated; Embodiment two: the last embodiment performs temperature control detection on the automobile sensor, and this embodiment further improves the temperature control efficiency by predicting the temperature control detection period based on the last embodiment. Please refer to Figure 2 As shown in the figure, the temperature control detection platform is communicatively connected with a detection period prediction unit; The temperature control detection platform generates a detection cycle prediction signal and sends the detection cycle prediction signal to the detection cycle prediction unit. After receiving the detection cycle prediction signal, the detection cycle prediction unit predicts the temperature control detection cycle of the temperature control area, infers whether the current temperature control detection cycle meets the temperature control detection efficiency, avoids the temperature control detection anomaly being outside the temperature control detection cycle, causes the temperature influence fault to exist the detection time lag, cannot timely perform the temperature control detection, and reduces the temperature control execution efficiency; The time point number ratio of the detection parameter floating peak increase time point and the detection parameter non-floating time point in the current detection cycle in the temperature control area is obtained, and the time length ratio of the detection parameter collection error rate rising time length and the same error rate falling time length in the current detection cycle in the temperature control area is obtained. The time point number ratio of the detection parameter floating peak increase time point and the detection parameter non-floating time point in the current detection cycle in the temperature control area, and the time length ratio of the detection parameter collection error rate rising time length and the same error rate falling time length in the current detection cycle in the temperature control area are compared with the time point number ratio threshold range and the time length ratio threshold range respectively: If the time point number ratio of the detection parameter floating peak increase time point and the detection parameter non-floating time point in the current detection cycle in the temperature control area is not in the time point number ratio threshold range, or the time length ratio of the detection parameter collection error rate rising time length and the same error rate falling time length in the current detection cycle in the temperature control area is not in the time length ratio threshold range, it is determined that the current detection cycle is abnormal, a cycle deviation signal is generated and sent to the temperature control detection platform. After receiving the cycle deviation signal, if one of the corresponding time point number ratio and the time length ratio exceeds the corresponding range, the corresponding detection cycle is shortened to improve the detection frequency. Otherwise, the corresponding detection cycle is lengthened to control the detection cost when meeting the detection demand; If the time point number ratio of the detection parameter floating peak increase time point and the detection parameter non-floating time point in the current detection cycle in the temperature control area is in the time point number ratio threshold range, and the time length ratio of the detection parameter collection error rate rising time length and the same error rate falling time length in the current detection cycle in the temperature control area is in the time length ratio threshold range, it is determined that the current detection cycle is normal, a cycle qualified signal is generated and sent to the temperature control detection platform; The application in use, the part position evaluation analysis unit will be marked as the temperature control area of the automobile part for temperature control detection, obtains the sensor distributed and arranged in the temperature control area and marks the position of each sensor as the detection position, obtains the part position evaluation analysis information, and substitutes into the formula to obtain the evaluation analysis coefficient of the sensor corresponding to the detection position in the automobile temperature control area, and the sensor is divided into important high impact end and non-important low impact end according to the evaluation analysis coefficient comparison; the temperature control detection analysis unit collects the temperature rise parameter and the temperature control parameter, and divides the current temperature control area running temperature environment into high intensity temperature environment and low intensity temperature environment according to the parameter comparison, and collects the heavy high impact information and the non-low impact information according to different types of running temperature environment, generates different types of signals according to information analysis and sends to the temperature control detection platform; the temperature influence analysis unit carries out temperature influence analysis on the temperature control detection process of the temperature control area.
