Description

Technical Field

[0001] The invention relates to the technical field of fault diagnosis, and in particular to an intelligent basic test box capable of realizing self-diagnosis. Background Art

[0002] Self-diagnosis technology uses the detection program to automatically detect the main parts of the instrument and locate the fault. The diagnosis function brings great convenience to the use and maintenance of the instrument and is a necessary means to improve the reliability of the instrument.

[0003] There are two types of instrument self-diagnosis. One is offline self-diagnosis, which refers to the self-diagnosis performed before or during the instrument executes the application program. Since this self-diagnosis is performed without the application program, it is called offline self-diagnosis. After the instrument is powered on, the instrument first enters the self-diagnosis program to tell the user whether the instrument is in normal working condition. In addition, the user can call the program at any time during the interval of the instrument's operation to detect whether the instrument is in normal condition. The other is online self-diagnosis, which refers to the self-diagnosis of the instrument during the normal working process of the instrument.

[0004] Diagnosis generally includes two aspects: on the one hand, it refers to the response when the instrument fails, which is a relatively basic self-diagnosis; on the other hand, it refers to the discovery and repair of potential faults in the instrument or when the accuracy and characteristics decrease. The self-diagnosis system of the instrument is generally an independent software and hardware module. To complete the self-diagnosis process, first find the key parts of the instrument, record and save various parameters in its normal measurement state and excited state, and note that historical records must also be saved. Secondly, each closed loop can be opened and tested at any time, so that different tasks can be completed according to different needs during the self-diagnosis process.

[0005] For the basic test box used to detect electronic sounding instruments, the relevant faults of the basic test box are still identified through manpower and experience, and automatic diagnosis cannot be achieved. Summary of the invention

[0007] An embodiment of the present invention provides an intelligent basic test box capable of self-diagnosis, comprising: a self-diagnosis module, wherein the self-diagnosis module comprises a diagnosis processing unit and a reference standard unit connected to each other; the reference standard unit is used to obtain a sampling reference value of a preset measurement parameter, and send the sampling reference value to the diagnosis processing unit; the diagnosis processing unit is also connected to a sampling standard of the intelligent basic test box, and is used to receive the sampling standard value of the sampling standard for the preset measurement parameter and the sampling reference value, and compare the sampling standard value with the sampling reference value, and perform fault diagnosis on the sampling standard according to the numerical difference between the sampling standard value and the sampling reference value.

[0008] Furthermore, the preset measurement parameters include temperature, relative humidity and air pressure.

[0009] Furthermore, when the diagnostic processing unit is used to diagnose faults of the sampling standard according to the numerical difference between the sampling standard value and the sampling reference value, it is specifically used to: compare the numerical difference with a preset threshold; if the numerical difference is greater than the preset threshold, it is determined that the sampling standard has failed; otherwise, it is determined that the sampling standard has not failed.

[0010] Furthermore, the reference standard unit includes a humidity-sensitive capacitor, and the humidity-sensitive capacitor is used to obtain the sampled reference value corresponding to the relative humidity.

[0011] Furthermore, the diagnostic processing unit is also connected to the external output port of the intelligent power module of the intelligent base test box, for obtaining the voltage signal and current signal output by the intelligent power module to the electronic sounding instrument, and performing fault diagnosis on the intelligent power module according to the voltage signal and the current signal.

[0012] Furthermore, the self-diagnosis module also includes a remote communication unit, and the remote communication unit is connected to the diagnosis processing unit and the remote control end to establish a communication connection between the diagnosis processing unit and the remote control end.

[0013] Furthermore, the diagnostic processing unit is also used to monitor the status of remote communication.

[0015] Furthermore, the display subunit is also used to display operation prompt information, and the operation prompt information includes prompt information displayed when the sampling standard fails, such as checking the water tank to add water or replace the gauze.

[0016] Furthermore, the reference standard unit is also used to calibrate the sampling standard.

[0017] The embodiment of the present invention provides an intelligent base test box capable of self-diagnosis. A self-diagnosis module is set in the intelligent reference box, and a sampling reference value measured by a reference standard unit of the self-diagnosis module is compared with a sampling standard value measured by a sampling standard of the intelligent base test box, thereby performing fault diagnosis on the sampling standard, thereby realizing automatic self-diagnosis of the intelligent reference box.

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Figure 1 FIG. 1 is a schematic diagram of the structure of an intelligent basic test box capable of realizing self-diagnosis provided by an embodiment of the present invention. Figure 1As shown, the intelligent basic test box includes a self-diagnosis module 1, and the self-diagnosis module 1 includes a diagnosis processing unit 10 and a reference standard unit 20 that are interconnected; the reference standard unit 20 is used to obtain a sampling reference value of a preset measurement parameter, and send the sampling reference value to the diagnosis processing unit 10; the diagnosis processing unit 10 is also connected to the sampling standard 2 of the intelligent basic test box, and is used to receive the sampling standard value of the preset measurement parameter of the sampling standard 2 and receive the sampling reference value, and compare the sampling standard value with the sampling reference value, and perform fault diagnosis on the sampling standard 2 according to the numerical difference between the sampling standard value and the sampling reference value.

[0023] The intelligent basic test box is used to detect the electronic sounding instrument. The intelligent basic test box includes a sampling standard 2 for obtaining the sampling standard value of the preset measurement parameters, and the preset measurement parameters are determined according to the measurement parameters of the electronic sounding instrument. For example, the current electronic sounding instrument is mainly used to measure temperature, relative humidity and air pressure, and the preset measurement parameters can be set to include temperature, relative humidity and air pressure. The sampling standard 2 compares the sampling standard value measured by it with the corresponding measurement value of the electronic sounding instrument to detect the performance of the electronic sounding instrument.

[0024] To achieve effective detection of the electronic sounding instrument, it is first necessary to ensure that the sampling standard 2 works stably and reliably. Therefore, the embodiment of the present invention realizes intelligent diagnosis of the sampling standard 2 by setting a self-diagnosis module 1 in the intelligent base test box. The self-diagnosis module 1 includes a diagnostic processing unit 10 and a reference standard unit 20; the reference standard unit 20 is used to obtain the sampling reference value of the preset measurement parameter and send the sampling reference value to the diagnostic processing unit 10. The reference standard unit 20 also needs to realize the sampling measurement of the preset measurement parameter. Compared with the sampling standard 2, the reference standard unit can use a measuring element with high reliability but slightly lower precision to reduce costs while ensuring measurement accuracy. Among them, the reference standard unit 20 provides reference data for qualitative analysis of the sampling standard 2.

[0025] The diagnostic processing unit 10 is connected to the reference standard unit 20 and the sampling standard 2 respectively, and is used to receive the sampling reference value measured by the reference standard unit 20 and the sampling standard value measured by the sampling standard 2, and compare the sampling standard value with the sampling reference value, and can compare the two in real time, and perform fault diagnosis on the sampling standard 2 according to the numerical difference between the sampling standard value and the sampling reference value. The diagnostic processing unit 10 can provide the user with the status information of the instrument (whether the instrument is working normally) by comparing and analyzing the numerical values ​​of the sampling standard 2 and the reference standard unit 20.

[0026] A preset threshold value may be set for the numerical difference. If the numerical difference is greater than the preset threshold value, the diagnosis processing unit 10 learns that the sampling standard 2 has failed; otherwise, it learns that the sampling standard 2 has not failed.

[0027] The embodiment of the present invention sets a self-diagnosis module in the intelligent reference box, compares the sampling reference value measured by the reference standard unit of the self-diagnosis module with the sampling standard value measured by the sampling standard of the intelligent reference box, and then performs fault diagnosis on the sampling standard, thereby realizing automatic self-diagnosis of the intelligent reference box.

[0028] Further, based on the above embodiment, the reference standard unit 20 includes a humidity-sensitive capacitor, and the humidity-sensitive capacitor is used to obtain the sampled reference value corresponding to the relative humidity.

[0029] The preset measurement parameters may include temperature, relative humidity and air pressure. The reference standard unit 20 may be provided with a measuring device that is more reliable than the sampling standard 2 but less accurate. For example, the sampling standard 2 usually uses a ventilated psychrometer method (which may be composed of two temperature platinum resistors, one of which is wrapped with a wet cloth) to measure relative humidity to ensure the accuracy of humidity measurement; however, due to the lack of water in the wet bulb or the contamination of the wet bulb gauze, problems may easily occur in humidity measurement, which requires inspection and disposal. Therefore, a highly reliable humidity-sensitive capacitor may be provided in the reference standard unit 20 to measure the reference value of relative humidity, that is, the sampling reference value corresponding to the relative humidity, so as to compare it with the sampling standard value measured by the sampling standard 2 to detect faults in a timely manner.

[0030] On the basis of the above-mentioned embodiment, the embodiment of the present invention improves the reliability of diagnosis by setting a humidity-sensitive capacitor to measure the reference value of relative humidity.

[0031] Figure 2 1 is a schematic diagram of the structure of an intelligent base test box capable of realizing self-diagnosis provided by another embodiment of the present invention. Further, based on the above embodiment, the diagnostic processing unit 10 is also connected to the external output port of the intelligent power module 3 of the intelligent base test box, and is used to obtain the voltage signal and current signal output by the intelligent power module 3 to the electronic sounding instrument, and perform fault diagnosis on the intelligent power module 3 according to the voltage signal and the current signal.

[0032] The external output port of the diagnostic processing unit 10 is connected to the electronic sounding instrument to supply power to the electronic sounding instrument. The diagnostic processing unit 10 is also connected to the external output port of the intelligent power module 3 of the intelligent base test box to obtain the voltage signal and current signal output by the intelligent power module 3 to the electronic sounding instrument, and perform fault diagnosis on the intelligent power module 3 according to the voltage signal and the current signal.

[0033] According to the working requirements of the electronic sounding instrument, the voltage preset value of the voltage signal and the current preset value of the current signal can be set respectively, the voltage preset value can be a voltage range, and the current preset value can be a current range. When the diagnostic processing unit 10 performs fault diagnosis on the intelligent power module 3 according to the voltage signal and the current signal, if it is determined that the voltage signal exceeds the voltage preset value or the current signal exceeds the current preset value, it is determined that the intelligent power module has a fault, otherwise, the intelligent power module has not a fault.

[0034] If the intelligent power module fails, it is further known that the electrical performance of the electronic sonde fails.

[0035] On the basis of the above-mentioned embodiment, the embodiment of the present invention realizes self-diagnosis of external power supply by collecting the output voltage and output current of the intelligent power module.

[0036] Further, based on the above embodiment, the self-diagnosis module 1 further includes a remote communication unit 30, and the remote communication unit 30 is connected to the diagnosis processing unit 10 and the remote control end to establish a communication connection between the diagnosis processing unit 10 and the remote control end.

[0037] The self-diagnosis module 1 further includes a remote communication unit 30, which is connected to the diagnosis processing unit 10 and the remote control terminal respectively to establish a communication connection between the diagnosis processing unit 10 and the remote control terminal. The self-diagnosis module 1 can send the fault diagnosis result to the remote control terminal, and the remote control terminal can also implement remote control and adjustment operations on the self-diagnosis module 1.

[0039] Further, based on the above embodiment, the diagnosis processing unit 10 is also used to monitor the status of remote communication.

[0040] The diagnosis processing unit 10 is also used to monitor the communication status between the diagnosis processing unit 10 itself and the remote control terminal, and the communication status includes a connection status and a disconnection status. If the communication status is detected to be a disconnection status, it is determined that a remote communication failure occurs.

[0041] The diagnosis processing unit 10 may also perform relevant monitoring on the remote communication unit 30 so as to timely discover communication failures.

[0042] On the basis of the above-mentioned embodiments, the embodiments of the present invention realize remote communication fault diagnosis by monitoring the communication status between the diagnosis processing unit and the remote control terminal.

[0043] Further, based on the above embodiment, the self-diagnosis module 1 also includes a human-computer interaction unit 40, and the human-computer interaction unit 40 is connected to the diagnostic processing unit 10; the human-computer interaction unit 40 includes a display subunit and an alarm subunit; the display subunit is used to display fault information, and the alarm subunit is used to perform sound and light alarm when a fault occurs.

[0044] The human-computer interaction unit 40 is used for local human-computer interaction. The human-computer interaction unit 40 is connected to the diagnosis processing unit 10, and includes a display subunit and an alarm subunit. Other subunits may be provided as needed to perform corresponding human-computer interaction, such as an input subunit.

[0045] The display subunit is used to display fault information, and the alarm subunit is used to sound and light alarm when a fault occurs. When the diagnosis processing module 10 determines that a fault occurs, it sends the corresponding fault information to the display subunit for display, and can also send it to the alarm subunit for sound and light alarm.

[0046] On the basis of the above-mentioned embodiments, the embodiments of the present invention realize timely acquisition of fault information by providing a human-computer interaction unit.

[0047] Further, based on the above embodiment, the display subunit is also used to display operation prompt information, and the operation prompt information includes prompt information for checking the water tank to add water or replace gauze when the sampling standard 2 fails.

[0048] The display subunit is also used to display operation prompt information, which includes prompt information for checking the water tank to add water or replace gauze when the sampling standard 2 fails, prompting the user to check the water tank to add water or replace gauze.

[0049] On the basis of the above-mentioned embodiment, the embodiment of the present invention includes operation prompt information for checking the water tank to add water or replace the gauze, which is conducive to the rapid troubleshooting of the fault.

[0050] Further, based on the above embodiment, the reference standard unit 20 is also used to calibrate the sampling standard 2 .

[0051] The reference standard unit 20 is also used to calibrate the sampling standard 2.

[0052] On the basis of the above-mentioned embodiment, the embodiment of the present invention enriches the function of the self-diagnosis module and improves the reliability of the intelligent basic test box by calibrating the sampling standard.
