Description

Technical Field

[0001] The present invention relates to the technical field of communication detection, and in particular to a detection method and a terminal for a communication module. Background Art

[0002] Communication equipment is widely used, and a single device needs to meet more and more functions. This is reflected in the hardware as the integrated design of functional module circuits one by one. The damage of a single functional module circuit may cause the equipment to be scrapped due to lack of function, resulting in waste. With the promotion of modularization of communication equipment, pluggable communication modules have been widely used. The maintenance method of replacing faulty communication modules has improved the utilization rate of the equipment body and saved costs. Faulty communication modules can also be returned to the factory for repair, and those that meet quality requirements can be recycled. If a communication module fails, directly repairing a single communication module instead of repairing the entire device greatly reduces material costs. However, this requires a lot of manpower and time for on-site communication module troubleshooting.

[0003] In the related art, fault detection of the communication module is generally performed based on a specific reference signal characteristic value. Since different communication modules have different version models, if different communication module versions all perform fault detection of the communication module according to the specific reference signal characteristic value, it is impossible to obtain a relatively accurate reference signal characteristic value, which is not conducive to the accurate detection of different fault events of the communication module. Summary of the invention

[0004] In view of this, the present invention provides a communication module detection method and terminal to solve the problem that if different communication module version models all perform communication module fault detection according to specific reference signal characteristic values, it is impossible to obtain relatively accurate reference signal characteristic values, which is not conducive to accurately detecting different fault events of the communication module.

[0056] 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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0057] Figure 1 is a circuit schematic diagram of a terminal according to an embodiment of the present invention.

[0058] The present disclosure provides a terminal, such as Figure 1 As shown, the terminal includes: a power supply module 11, a current detection module 12, a voltage detection module 13, an interface module 14, a communication module 15 connected in sequence, and a control module 16 connected to the power supply module 11, the current detection module 12, the voltage detection module 13, and the interface module 14, wherein the communication module 15 is plugged into the interface module 14 to establish a communication connection with the control module 16.

Then it is output to the current detection module 12 through the P-channel MOS tube V1. When CTL_P is at a high level, the NPN transistor Q1 is turned on, the base of V1 is pulled down to a low level, and V1 is turned on. When CTL_P is at a low level, the NPN transistor Q1 is turned off, the base of V1 is pulled up by the pull-up resistor R2, Vg=Vs, V1 is turned off, and R1 is a current limiting resistor.

The number of interface socket holes of the interface module is different according to the requirements of different communication modules. It includes 1 power input, 1 power ground, 1 plug detection pin, and several insertion signal pins. The plug detection pin DET_Q is connected to a pull-up resistor and pulled up to the power level of the control module.

[0065] exist Figure 1 In the embodiment, the control module 16 includes a control I / O pin CTL_P, sampling input pins ADC_I, ADC_V, and an I / O input pin DET_Q. The control module 16 is connected to the power supply module 11 through CTL_P, ADC_I is connected to the current detection module 12, ADC_V is connected to the voltage detection module 13, and DET_O is connected to the interface module 14.

[0066] exist Figure 1 In the figure, the communication module 15 includes a communication chip JP2 and a resistor R11. The communication module 15 is plugged into the module hardware interface corresponding to the terminal. In addition to the necessary power interface and interface module 14, it also needs to have a separate plug-in signal for providing identification to the terminal. The signal pin does not need a complex design, and only needs to be connected to a 100Ω current limiting resistor and pulled down to the ground.

[0067] In the terminal of the disclosed embodiment, there is no need for too many requirements for the external communication module, and it is sufficient to include a 1-way plug-in detection pin, and the required resources are simple and easy to implement. The disclosed embodiment is for communication modules with the same interface definition, such as HPLC&HRF dual-mode communication module, HPLC&Bluetooth dual-mode communication module, HPLC communication module, 4G communication module and many other types. Due to different functions and different design schemes, the power consumption of communication modules also varies greatly. The corresponding specifications have relatively broad requirements for the power consumption range of communication modules. It is difficult to judge whether the power consumption of the communication module is abnormal according to the power consumption range of the specification. Each manufacturer also keeps the module parameters designed by itself confidential, and it is impossible to obtain more accurate parameters. When the communication module is first inserted into the terminal, the terminal will automatically sample the actual signal characteristic value of the communication module through the circuit and algorithm of the main body, and generate the reference signal characteristic value corresponding to the current version model and save it in the storage module of the terminal. The terminal will update the reference signal characteristic value for different situations.

[0068] Furthermore, during the operation of the communication module, the terminal regularly collects actual signal characteristic values ​​and compares them with the saved reference signal characteristic values, and then feeds back the working status, plug-in and unplugging, power consumption, failure, etc. of the terminal's external communication module. For abnormal conditions, the terminal makes its own judgments and takes self-recovery and protection measures to avoid new problems caused by continued abnormal operation of the communication module, records abnormal status information and reports it to the platform to remind management personnel to deal with it in time.

[0069] According to an embodiment of the present invention, an embodiment of a detection method for a communication module is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0070] In this embodiment, a communication module detection method is provided, which is applied to a terminal, and can be specifically applied to a mobile terminal, such as a mobile phone, a tablet computer, etc. Figure 3 is a flow chart of a communication detection method according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0071] Step S301, obtaining the current version model of the communication module.

[0072] Specifically, in each communication process between the communication module and the terminal, each communication module has its own corresponding version model, so each time a user inserts its communication module into the terminal, it is necessary to obtain the current version model of the communication module. For example, when user A inserts its communication module into the terminal, the current version model of user A is obtained, and when user B inserts its communication module into the terminal, the current version model of user B is obtained.

[0073] Step S302, determining whether the current version model is a pre-stored version model.

[0074] Specifically, each time the current version model of the communication module of this communication is matched with the version model pre-stored in the controller to determine whether the current version model of the communication module is the pre-stored version model.

[0075] Step S303: if the current version model is not a pre-stored version model, the actual signal characteristic value of the communication module is obtained, and a reference signal characteristic value corresponding to the current version model is generated.

[0076] Specifically, if the current version model is not a pre-stored version model, the actual signal characteristic value of the communication module is obtained, and the reference signal characteristic value corresponding to the current version model is generated. For example, when user A inserts his communication module into the terminal, if the current version model of user A is not a pre-stored version model, the actual signal characteristic value of the communication module is obtained, and the actual signal characteristic value of the communication module is used as the reference signal characteristic value corresponding to the current version model.

[0077] As a specific example, the reference signal characteristic value includes a reference current characteristic value, and the reference current characteristic value includes a reference average current characteristic value and a reference maximum current characteristic value.

[0078] Step S304, if the current version model is a pre-stored version model, obtain the actual signal characteristic value of the communication module, and determine whether the deviation between the actual signal characteristic value of the communication module and the reference signal characteristic value corresponding to the current version model of the communication module is greater than a preset threshold; wherein, if the deviation is not greater than the preset threshold, update the reference signal characteristic value corresponding to the current version model of the communication module; if the deviation is greater than the preset threshold, determine a fault event.

[0079] As a specific example, the actual signal characteristic value of the communication module includes: an actual current characteristic value, and the actual current characteristic value includes an actual average current characteristic value and an actual maximum current characteristic value.

[0080] Specifically, if the current version model is a pre-stored version model, the actual signal characteristic value of the communication module is obtained, and the actual signal characteristic value is compared with the reference signal characteristic value, thereby obtaining the individual difference of the communication module. The preset threshold value can be 10% of the reference average current characteristic value, or other values, which are not specifically limited here. If the deviation between the actual signal characteristic value and the reference signal characteristic value is not greater than the preset threshold, the reference signal characteristic value corresponding to the current version model of the communication module is updated, and if the deviation between the actual signal characteristic value and the reference signal characteristic value is greater than the preset threshold, the fault event is determined. The fault events here include: fault events that the terminal can handle by itself and fault events that the terminal cannot handle by itself (fault events that require professional personnel to check), for example, the fault events that the terminal can handle by itself include abnormal power consumption fault events of the communication module, and events of abnormal pin insertion faults. The fault events that the terminal cannot handle by itself include: short circuit fault events of the power supply circuit of the communication module, open circuit fault events of the power supply circuit of the communication module, damage fault events of the communication module, leakage fault events of the communication module, abnormal insertion fault events of the communication module, etc.

[0081] The detection method of the communication module in the embodiment of the present disclosure compares the current version model of the communication module with the pre-stored version model, further generates the reference signal characteristic value corresponding to the current version model in combination with the reference signal characteristic value corresponding to the current version model, and compares the difference between the deviation between the reference signal characteristic value corresponding to the current version model and the actual signal characteristic value and the preset threshold, and then further updates the reference signal characteristic value corresponding to the current version model of the communication module and determines the fault event. Finally, the embodiment of the present disclosure can accurately extract the reference signal characteristic values ​​corresponding to the communication modules of different version models, which is conducive to the accurate detection of different fault events of the communication module.

[0082] In this embodiment, a communication module detection method is provided, which is applied to a terminal, and can be specifically applied to a mobile terminal, such as a mobile phone, a tablet computer, etc. Figure 4 is a flow chart of a communication detection method according to an embodiment of the present invention. Figure 4 As shown, in the above step S304, updating the reference signal characteristic value corresponding to the current version model of the communication module includes:

[0083] Step S401, determining whether a deviation between an actual average current characteristic value and a reference current characteristic value is greater than a preset threshold.

[0084] The actual signal characteristic value includes an actual current characteristic value, the actual current characteristic value includes an actual average current characteristic value and an actual maximum current characteristic value, and the reference signal characteristic value includes a reference current characteristic value.

[0085] Step S402 , if the deviation between the actual average current characteristic value and the reference current characteristic value is not greater than a preset threshold, an updated reference signal characteristic value is obtained based on the actual current characteristic values ​​sampled multiple times within a preset time.

[0086] Specifically, the reference current characteristic value here refers to the reference average current characteristic value. The reference average current characteristic value is a reference average current characteristic value pre-stored before the update. For example, when user A inserts his communication module into the terminal, the actual average current characteristic value of user A is compared with the pre-stored reference current characteristic value. The pre-stored reference current characteristic value is based on the reference average current characteristic value generated by the previous user B or the updated reference current characteristic value. The deviation between the actual average current characteristic value and the reference current characteristic value is compared to obtain the difference between the two. The preset threshold value can be 10% of the preset average current characteristic value, or other values, which are not specifically limited here.

[0087] Furthermore, the actual average current characteristic value includes an actual static average current characteristic value and an actual dynamic average current characteristic value, and the actual maximum current characteristic value includes an actual maximum dynamic current characteristic value and an actual maximum static current value.

[0088] If the deviation between the actual average current characteristic value and the reference current characteristic value is not greater than the preset threshold, the updated reference signal characteristic value is obtained based on the actual current characteristic value sampled multiple times within the preset time. For example, in the actual current characteristic value acquisition process of the communication module, when the communication module is inserted into the terminal, the power interface of the terminal provides a fixed voltage, the communication module is started, and the actual current characteristic value is generated. The terminal samples the actual current characteristic value once per second, and the sampling continues for 60 minutes. A total of 3600 actual current characteristic values ​​are sampled and temporarily stored. Within this 60 minutes, the terminal sends a command to the communication module, dividing 60 minutes into 6 samplings, each sampling time is 10 minutes, and the communication module maintains dynamic communication for 2 minutes and static for 8 minutes in this 10 minutes. A total of 6 times (dynamic time + static time), calculate the average value of the actual current characteristic value in the dynamic time and static time in each sampling. Therefore, the actual average current characteristic value sampled multiple times within the preset time can be obtained in this way.

[0089] Based on the actual average current characteristic values ​​sampled multiple times within the preset time calculated above, the general specification sets a limit on the charging time of the supercapacitor of the communication module, which shall not exceed 30 minutes. Therefore, the first actual static current average value to the sixth actual static current average value and the first actual dynamic current average value to the sixth actual dynamic current average value can be compared. If both the actual static and actual dynamic current average values ​​change from high to low, it means that the communication module circuit contains a supercapacitor, and the initial charging of the supercapacitor causes a significant change in current consumption; if there is no change from high to low, it means that the communication module circuit does not contain a supercapacitor.

[0090] On the basis of the actual average current characteristic value sampled multiple times within the preset time calculated above, for the communication module without supercapacitor, the sampled current data in the dynamic time and static time of the fourth, fifth, and sixth samplings in the following 30 minutes of continuous sampling for 60 minutes are used as the sample interval to obtain the actual maximum current characteristic value (actual maximum dynamic current characteristic value, actual maximum static current characteristic value) and the actual average current characteristic value (actual average dynamic current characteristic value, actual average static current characteristic value). These extracted information are bound to the model version read as the reference current characteristic value and saved in the storage unit of the control module as the judgment basis for the working status of each subsequent module. For the communication module with supercapacitor, the sampling value of the second second when it is first powered on is additionally recorded as the maximum value of the capacitor (excluding the error caused by the instantaneous current pulse when the power is turned on in the first second), and the model version read is also bound as the standard current characteristic value and saved in the storage unit of the control module.

[0091] In some optional embodiments, the reference signal characteristic value includes a reference maximum current characteristic value; wherein, based on the actual current characteristic values ​​sampled multiple times within a preset time, the updated reference signal characteristic value is obtained, including:

[0092] Step a1, obtaining the actual maximum current characteristic value from the actual current characteristic values ​​sampled multiple times within a preset time.

[0093] Specifically, the preset time can be a preset 60 minutes, and the actual maximum current characteristic value includes the actual maximum dynamic current value and the actual maximum static current value, that is, the actual maximum dynamic current characteristic value and the actual maximum static current characteristic value are obtained from multiple actual current characteristic values ​​within the preset 60 minutes.

[0094] Step a2: selecting the maximum value from the actual maximum current characteristic value and the reference maximum current characteristic value as the current update parameter of the reference maximum current characteristic value.

[0095] Specifically, a maximum value is selected from the actual maximum current characteristic value and the pre-stored reference maximum current characteristic value as the current update parameter of the reference maximum current characteristic value.

[0096] Step a3, updating the reference maximum current characteristic value according to the current update parameter to obtain an updated reference signal characteristic value.

[0097] For example, under the condition that the deviation between the actual average current characteristic value and the reference current characteristic value is no greater than a preset threshold, when user A inserts his communication module into the terminal, the actual maximum current characteristic value is obtained from the actual current characteristic value of user A's communication module sampled multiple times within a preset time, and the maximum value is selected from the actual current characteristic value of user A's communication module and the reference maximum current characteristic value generated or updated by the previous communication module as the current update parameter of the reference maximum current characteristic value of user A's current communication.

[0098] In some other optional implementations, obtaining an updated reference signal characteristic value based on actual current characteristic values ​​sampled multiple times within a preset time includes:

[0099] Step b1, based on the actual average current characteristic values ​​sampled multiple times within a preset time, calculate the average result of the actual average current characteristic values ​​sampled multiple times within the preset time by the communication module of this communication and the reference average current characteristic value.

[0100] Specifically, the actual average current characteristic value included here includes an actual dynamic average current characteristic value and an actual static average current characteristic value, and the reference average current characteristic value includes a reference dynamic average current characteristic value and a reference static current characteristic value. Therefore, based on the actual dynamic average current characteristic value sampled multiple times within the preset time, the average result of the actual dynamic average current characteristic value sampled multiple times within the reference time and the reference dynamic average current characteristic value of the communication module of this communication is calculated, and based on the actual static average current characteristic value sampled multiple times within the reference time, the average result of the actual static average current characteristic value sampled multiple times within the reference time and the reference static average current characteristic value of the communication module of this communication is calculated.

[0101] Step b2: using the average result as the updated reference average current characteristic value.

[0102] For example, when specifically updating the benchmark average dynamic current characteristic value and the benchmark static current characteristic value, the benchmark average current characteristic value is a pre-stored benchmark average current characteristic value. For updating the actual dynamic average current value, under the condition that the deviation between the actual average current characteristic value and the benchmark average current characteristic value is not greater than the preset threshold, the actual dynamic average current characteristic value and the benchmark dynamic average current characteristic value are averaged to replace the previously pre-stored benchmark average dynamic current characteristic value. For static, the actual static average current value and the pre-stored benchmark average static current characteristic value are averaged to replace the previously pre-stored benchmark static average current characteristic value.

[0103] Under the condition that the deviation between the actual average current characteristic value and the reference current characteristic value is not greater than a preset threshold, the embodiment of the present disclosure obtains an updated reference signal characteristic value based on the actual current characteristic values ​​sampled multiple times within a preset time. Ultimately, the embodiment of the present disclosure can accurately update the reference signal characteristic values ​​corresponding to communication modules of different versions and models, which is facilitating the accurate detection of different fault events of the communication module.

[0104] like Figure 5 As shown in FIG. 1 , it is a specific flow chart of updating the reference signal characteristic value corresponding to the current version model of the communication module in the embodiment of the present disclosure. Figure 5 In the communication terminal, each time the user inserts a new communication module into the communication terminal, the current version information is first read to determine whether it is a pre-stored version model. If so, the actual signal characteristic value of the communication module is obtained. If not, the actual signal characteristic value is obtained and bound to the current version model as a set of new reference signal characteristic values. After obtaining the actual signal characteristic value of the communication module, it is determined whether the deviation between the actual signal characteristic value of the communication module and the reference signal characteristic value corresponding to the current version model of the communication module is greater than 10%. If so, a fault event is determined. If not, based on the actual current characteristic values ​​sampled multiple times within a preset time, an updated reference signal characteristic value is obtained, and a new reference signal characteristic value is generated and saved as a reference for subsequent fault state judgment.

[0105] In this embodiment, a communication module detection method is provided, which is applied to a terminal, and can be specifically applied to a mobile terminal, such as a mobile phone, a tablet computer, etc. Figure 6 is a flow chart of a communication detection method according to an embodiment of the present invention. Figure 6 As shown, the actual signal characteristic value includes a current sampling measurement value, a voltage sampling measurement value, and an insertion signal when the communication module is inserted into the interface module, wherein the fault event is determined in the above step S304, including:

[0106] Step S601, determining a fault event according to a current sampling measurement value, an insertion signal when a communication module is inserted into an interface module, and a voltage sampling measurement value.

[0107] Specifically, the fault events here include: fault events that the terminal can handle by itself and fault events that the terminal cannot handle by itself (fault events that need to be inspected by professionals). For example, the fault events that the terminal can handle by itself include abnormal power consumption fault events of the communication module and abnormal insertion pin fault events. The fault events that the terminal cannot handle by itself include: short circuit fault events in the power supply circuit of the communication module, open circuit fault events in the power supply circuit of the communication module, damage fault events in the communication module, leakage fault events in the communication module, and abnormal insertion fault events in the communication module.

[0108] Since communication modules often become loose and fall off, communication is abnormal, and damaged, the communication platform cannot obtain the functional information of the terminal and its communication module. When the fault status is uncertain, it can only arrange personnel to deal with it. The problems of looseness and falling off can be handled by ordinary personnel after checking; in the case of communication abnormalities and damage, professionals are required to check and provide treatment plans. When the communication site situation is completely unclear, arranging the wrong personnel to deal with the problem will result in untimely handling of the fault problem and repeated waste of personnel attendance. Therefore, generating different types of fault events is conducive to quickly locating communication fault problems and helping managers to reasonably arrange personnel for on-site maintenance, rather than blindly dispatching maintenance personnel to blindly detect faults when the fault is unknown, thereby achieving the purpose of reducing maintenance costs and improving detection efficiency.

[0109] In some optional implementations, determining a fault event according to an insertion signal when the communication module is inserted into the interface module includes:

[0110] Step c1, determining whether the insertion signal when the communication module is inserted into the interface module is a high level signal or a low level signal.

[0111] Step c2: if the insertion signal when the communication module is inserted into the interface module is a high level signal, it is determined that the communication module is not inserted into the terminal.

[0112] Step c3, recording the abnormal insertion failure event of the communication module, and reporting the abnormal insertion failure event to the fault handling platform.

[0113] Step c4: if the insertion signal when the communication module is inserted into the interface module is a low level signal, it is determined that the communication module is normal.

[0114] Therefore, when an abnormal insertion fault event occurs in the communication module, the terminal cannot handle it by itself, but reports the abnormal insertion fault event to the fault handling platform and waits for professionals to come and check and give corresponding handling measures, which is conducive to timely and targeted resolution of the fault event.

[0115] In some optional implementations, determining a fault event according to a current sampling measurement value and an insertion signal when the communication module is inserted into the interface module includes:

[0116] Step d1, determining whether the current sampling measurement value is greater than the voltage divider resistor current value and not greater than the second current maximum value;

[0117] Specifically, the current sampling measurement value includes the voltage divider resistor current value I 0 , the second maximum current I 2 , detection current value I, second current maximum value I 2 Refers to the actual maximum current characteristic value when the super capacitor inside the communication module is charged + communicating (without super capacitor, I 2 =I 1 ), I 1 It refers to the actual maximum dynamic current characteristic value when the communication module without supercapacitor communicates.

[0118] Specifically, it is determined whether the detection current value satisfies I 0 <I≤I 2 .

[0119] Step d2: if the detected current value I is equal to the current value of the voltage-dividing resistor, it is determined that an abnormal insertion fault occurs in the communication module, and the abnormal insertion fault of the communication module is recorded as a second fault event;

[0120] Specifically, if I=I0, it is determined that an insertion abnormality fault occurs in the communication module.

[0121] Step d3: If the detected current value is greater than the current consumption value of the voltage-dividing resistor and is not greater than the second current maximum value, it is determined that the communication module is normal.

[0122] Specifically, the detection current value I satisfies I 0 <I≤I 2 , confirm that the communication module is normal.

[0123] like Figure 7 The figure is a flow chart of the communication module plug-in detection in the embodiment of the present disclosure. The above steps c1 to c4, and steps d1 to d3 correspond to Figure 7 Schematic diagram of the Figure 7 In the present invention, the two methods of judging the insertion and removal of the communication module complement each other, thereby improving the accuracy of judging the insertion of the communication module.

[0124] exist Figure 7In the hardware interface of the terminal, the communication module is inserted into the terminal. When a communication module with normal functions is inserted into the terminal, the detection pin is pulled down to provide a low-level signal, which is recognized by the control module detection pin, and the control module determines that a communication module is inserted; when the communication module is inserted, the power is turned on, and the communication module starts to consume current. The control module detects the detection current value I, and the detection current value I is the second maximum current value I 2 If the range is within the range, it means that a communication module is inserted. The level change of the specified pin and the change of the power interface current are used as the basis for judging whether the communication module is inserted normally. On the contrary, the low level signal of the control module detection pin becomes a high level, and I = I 0 , indicating that the communication module is loose and has fallen off. At this time, record the abnormal insertion of the communication module, report it to the fault handling platform, and arrange for ordinary personnel to restore it on site.

[0125] In some optional implementations, the current sampling measurement value includes a detection current value, and the voltage sampling measurement value includes a detection voltage value; wherein, determining a fault event according to the current sampling measurement value, an insertion signal when the communication module is inserted into the interface module, and the voltage sampling measurement value includes:

[0126] Step e1: if the insertion signal is a low level signal and the communication fails, and both the detection voltage value and the detection current value are zero, it is determined that the fault event is a short circuit fault in the power supply circuit of the communication module.

[0127] Specifically, when the communication module is running, there will be a variety of fault conditions, such as abnormal communication and abnormal power consumption. When the terminal initiates a communication command to the communication module, the control module detects the three signals ADC_I, ADC_V, and DET_Q to calculate I and U for analysis. Among them, I and U are the average values ​​of 3 samples. The detection voltage value is U, and the detection current value is 0. If U=0, I=0, DET_Q is low level, and communication fails; under this condition, the terminal determines that it is short-circuit protection, the power supply of the communication module is short-circuited and damaged, and the short-circuit protection event is recorded and reported to the fault handling platform to remind the management personnel to handle it in time.

[0128] Since the short circuit failure of the communication module is a failure that the terminal cannot handle by itself, the embodiment of the present disclosure executes the above steps, based on the detection voltage value and the detection current value, and combined with the insertion signal and the communication result, it can promptly determine that the communication module has a short circuit failure, record the short circuit failure event, and upload the short circuit failure event to the fault handling platform, and then dispatch relevant short circuit maintenance personnel to perform targeted fault repairs, rather than directly and blindly dispatching maintenance personnel to blindly detect the fault when the fault is unknown, thereby achieving the purpose of reducing maintenance costs and improving detection efficiency.

[0129] In some optional implementations, the current sampling measurement value includes a detection current value and a voltage divider resistor current value, and the voltage sampling measurement value includes a detection voltage value and an output voltage value, wherein the fault event is determined according to the current sampling measurement value, an insertion signal when the communication module is inserted into the interface module, and the voltage sampling measurement value, including:

[0130] Step f1, if the insertion signal is a low level signal and the communication fails, and the detection voltage value is equal to the output voltage value and the detection current value is equal to the voltage divider resistor current value, it is determined that the fault event is a circuit breaker event in the power supply circuit of the communication module.

[0131] Specifically, the detection voltage value is U, the output voltage value is VOUT, the detection current value is I, and the voltage divider resistor current value is I 0 If U=VOUT,I=I 0 , DET_Q is low level, communication fails; under this condition, the terminal determines that the communication module has a power failure, records the power open circuit event, and reports it to the fault handling platform.

[0132] Since the open circuit fault of the communication module is a fault that the terminal cannot handle by itself, the embodiment of the present disclosure can timely determine the open circuit fault of the communication module by executing the above steps based on the detection voltage value, output voltage value, detection current value and current value of the voltage divider resistor, and combining the insertion signal and communication results, and record the open circuit fault event, upload the open circuit fault event to the fault processing platform, and then dispatch relevant open circuit maintenance personnel to carry out targeted fault maintenance. Instead of blindly dispatching maintenance personnel to blindly detect faults when the fault is unknown, the purpose of reducing maintenance costs and improving detection efficiency is achieved.

[0133] In some optional implementations, the current sampling measurement value includes a detection current value, a voltage divider resistor current value, and a first current maximum value, and the voltage sampling measurement value includes a detection voltage value and an output voltage value; wherein, determining a fault event according to the current sampling measurement value, an insertion signal when the communication module is inserted into the interface module, and the voltage sampling measurement value includes:

[0134] Step g1, if the insertion signal is a low level signal and the communication fails, and the detection voltage value is equal to the output voltage value, the detection current value is greater than the voltage divider resistor current value and is not greater than the first current maximum value, the power supply module is controlled to be turned off to reset the communication module.

[0135] Specifically, the detection voltage value is U, and the output voltage value is VOUT. If U=VOUT, I 0 <I≤I 1 , DET_Q low level, communication failed; under this condition, I and U are normal, the control power supply module to reset the communication module. 1It refers to the actual maximum dynamic current characteristic value when the communication module without supercapacitor communicates.

[0136] Step g2: when the power supply module is turned on, determine whether the communication module has resumed normal communication.

[0137] Step g3: if the communication module cannot restore normal communication, it is determined that the fault event is an event in which a chip of the communication module is damaged.

[0138] Step g4: if the communication module resumes normal communication, it is determined that the fault event is an event in which a program abnormality fault occurs in the communication module.

[0139] Specifically, when U = VOUT, I 0 <I≤I 1 , DET_Q is low level, communication fails; it is judged as abnormal communication. The power supply module is controlled to be turned off and on by controlling the level change of CTL_P. When the power supply module is turned on, it is judged whether the communication module has restored normal communication. If normal communication can be restored, the program abnormal event is recorded and the log is stored for reference; if it is not restored to normal, it is judged that the communication chip of the communication module is damaged, the hardware abnormal event is recorded, and the fault handling platform is reported.

[0140] Since the communication chip damage in the communication module is a fault that the terminal cannot handle by itself, the embodiment of the present disclosure can timely determine the communication chip damage fault in the communication module based on the detection voltage value, output voltage value, detection current value, voltage divider resistor current value, the first current maximum value of the communication module and the second current consumption maximum value of the communication module by executing the above steps, and record the communication chip damage fault event, upload the communication chip damage fault event to the fault processing platform, and then dispatch maintenance personnel for the relevant communication chip damage fault to carry out targeted fault repair. Instead of directly and blindly dispatching maintenance personnel to blindly detect faults when the fault is unknown, the purpose of reducing maintenance costs and improving detection efficiency is achieved.

[0141] In some optional implementations, the current sampling measurement value includes a detection current value, a voltage divider resistor current value, and a first current maximum value, and the voltage sampling measurement value includes a detection voltage value and an output voltage value; wherein, according to the current sampling measurement value, an insertion signal when the communication module is inserted into the interface module, and the voltage sampling measurement value, determining the fault event further includes:

[0142] Step h1, if the insertion signal is a high level signal and the communication is normal, and the detection voltage value is equal to the output voltage value, the detection current value is greater than the voltage divider resistor current value and is not greater than the first current maximum value, it is determined that the fault event is an abnormal insertion pin fault of the communication module.

[0143] Specifically, the detection voltage value is I, the output voltage value is VOUT, and the maximum value of the first current is I 1 , the I 1 It refers to the actual maximum dynamic current characteristic value when the communication module without super capacitor communicates. If U=VOUT,I 0 <I≤I 1 , DET_Q high level. Communication is normal; under this condition, it is determined that the insertion pin is abnormally open, but it does not affect the normal operation of the communication module. Record the abnormal events of the insertion pin for reference.

[0144] Since the pin abnormality failure of the communication module is a failure that the terminal can handle by itself, the embodiment of the present disclosure executes the above steps, based on the detection voltage value, the output voltage value, the detection current value, the first current maximum value and the voltage divider resistor current value, and combines the insertion signal and the communication result, it can promptly determine that the pin abnormality failure of the communication module has occurred, and record the pin abnormality failure event of the communication module, and record the pin abnormality failure event of the communication module on the fault handling platform without reporting it. The terminal can handle the fault by itself, instead of blindly dispatching maintenance personnel to blindly detect the fault in the event of an unknown fault, thereby achieving the purpose of reducing maintenance costs and improving detection efficiency.

[0145] In some optional implementations, the current sampling measurement value includes a detection current value and a second current maximum value, and the voltage sampling measurement value includes a detection voltage value and an output voltage value; wherein, determining a fault event according to the current sampling measurement value, an insertion signal when the communication module is inserted into the interface module, and the voltage sampling measurement value, comprises:

[0146] Step i1, if the insertion signal is a low level signal and the communication fails, and the detection voltage value is equal to the output voltage value, the detection current value is greater than the second current maximum value and not greater than the preset power short circuit protection threshold, the power supply module is controlled to be turned off to reset the communication module.

[0147] Specifically, the detection voltage value is U, the output voltage value is VOUT, and the second current maximum value is I 2 , the I 2 Refers to the actual maximum current characteristic value when the super capacitor inside the communication module is charged + communicating (without super capacitor, I 2 =I 1 ), the preset power short circuit protection threshold is I 3 , the I 3 Refers to the communication module power short circuit protection threshold. If U=VOUT, I 2 <I≤I 3 , DET_Q is low level, communication fails; under this condition, the power consumption is abnormal, and the control power supply module is turned off to reset the communication module.

[0148] Step i2, when the power supply module is turned on, determining whether the communication module has resumed normal communication;

[0149] Step i3: if the communication module resumes normal communication, it is determined that the fault event is an abnormal power consumption fault of the communication module;

[0150] Step i4: if the communication module cannot restore normal communication, determine that the fault event is an event in which the communication module is damaged.

[0151] Specifically, on the basis of the above, when the power supply module is turned on, normal communication is restored, abnormal power consumption events are recorded and logs are stored for reference; if it is not restored to normal, it is judged that the communication module is damaged, and CTL_P is controlled to shut down the power supply to prevent other hidden dangers caused by the continuous high current of the communication module, record the communication module damage event, and report it to the fault handling platform.

[0152] Since the communication module damage fault is a fault that the terminal cannot handle by itself, the embodiment of the present disclosure can timely determine the communication module damage fault by executing the above steps based on the second current maximum value of the communication module, the detection current value and the power short-circuit protection threshold, and combined with the insertion signal and the communication result, and record the communication module damage fault event, upload the communication module damage fault event to the fault processing platform, and then dispatch maintenance personnel for the relevant communication module damage fault to carry out targeted fault repair. Instead of directly and blindly dispatching maintenance personnel to blindly detect faults when the fault is unknown, the purpose of reducing maintenance costs and improving detection efficiency is achieved.

[0153] In some optional implementations, the current sampling measurement value includes a detection current value and a second current maximum value, and the voltage sampling measurement value includes a detection voltage value and an output voltage value; wherein, determining a fault event according to the current sampling measurement value, an insertion signal when the communication module is inserted into the interface module, and the voltage sampling measurement value, comprises:

[0154] Step j1, if the insertion signal is a low level signal and the communication is normal, and the detection voltage value is equal to the output voltage value, the detection current value is greater than the second current maximum value and less than the preset power supply short circuit protection threshold, it is determined that the fault event is a leakage fault in the communication module.

[0155] Specifically, the detection voltage value is U, the output voltage value is VOUT, and the second current maximum value is I 2 , the I 2 Refers to the actual maximum current characteristic value when the super capacitor inside the communication module is charged + communicating (without super capacitor, I 2 =I 1 ), the preset power short circuit protection threshold is I 3 , the I 3Refers to the communication module power short circuit protection threshold. If U=VOUT, I 2 <I<I 3 Abnormal, DET_Q low level, communication is normal; under this condition, it is determined that the communication module has abnormal leakage, which may be caused by leakage of the super capacitor inside the communication module. Record the communication module leakage event and report it to the fault handling platform for prompt processing.

[0156] Since the leakage fault of the communication module is a fault that the terminal cannot handle by itself, the embodiment of the present disclosure can timely determine the abnormal leakage fault of the communication module by executing the above, based on the detection voltage value, output voltage value, detection current value, second current maximum value and preset power supply short circuit protection threshold, and combined with the insertion signal and communication result, and record the abnormal leakage fault event of the communication module, upload the abnormal leakage fault event of the communication module to the fault processing platform, and then dispatch maintenance personnel of the abnormal leakage fault of the relevant communication module to carry out targeted fault repair. Instead of directly and blindly dispatching maintenance personnel to blindly detect faults in the case of unknown faults, the purpose of reducing maintenance costs and improving detection efficiency is achieved.

[0157] like Figure 8 As shown in the figure, the terminal provides different response methods for different types of communication module failure events. Some abnormal problems can be solved autonomously on the terminal side, reducing the number of manual maintenance times and maintenance costs. The protection measures triggered by the terminal for abnormal power consumption avoid safety hazards caused by overheating of the communication module and ensure the normal operation of the terminal. At the same time, the records of different abnormal events provide guidance for subsequent maintenance.
