[0051] At present, with the development of information technology, modern communication methods are diverse. The communications commonly used by modern people include Internet communication, mobile communication, satellite communication, fiber optic communication and radio communication.
[0052] In the related art, in applications with high information security requirements, such as internal corporate communication, traditional automatic telephones are still the main means of communication. However, in actual applications, it is found that when the telephone handle is not properly returned to its original position after the call is completed or the telephone handle is accidentally touched by a person, the telephone will be abnormally picked up, resulting in the inability to make incoming calls, affecting the user experience.
[0053] In view of this, a telephone status recognition method, device, electronic device and storage medium are provided in the embodiments of the present application. By detecting and analyzing the circuit characteristic values of the line, the telephone status change trend of the telephone is determined, so as to quickly identify whether the telephone is in an abnormal off-hook state of being off-hook for a long time, which helps to give off-hook warning prompts in time, avoid the situation where the phone cannot make calls, and effectively improve the user experience.
[0054] It should be noted that in each specific implementation of the present application, when it comes to the need to perform relevant processing based on data related to user identity or characteristics such as user information, user behavior data, user historical data, and user location information, the user's permission or consent will be obtained first, and the collection, use, and processing of these data will comply with relevant laws, regulations, and standards.

After clearly obtaining the user's separate permission or consent, the necessary user-related data for the normal operation of the embodiment of the present application will be obtained.
[0055] The specific implementation of the embodiment of the present application is described in detail below in conjunction with the accompanying drawings. First, a method for identifying a phone state provided in the embodiment of the present application is described in conjunction with the accompanying drawings.
[0056] Please refer to Figure 1 , Figure 1 1 is a schematic diagram of an implementation environment of a method for identifying a telephone state provided by an embodiment of the present application. In the implementation environment, the main software and hardware entities involved include a terminal processor 110 and a server 120.
[0057] Specifically, the terminal processor 110 may be installed with a relevant telephone state identification method control program, and the server 120 is a background server of the control program. The terminal processor 110 and the background server 120 are connected in communication. The telephone state identification method provided in the embodiment of the present application may be executed on the terminal processor 110 side.
[0058] Server 120 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers. It can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), as well as big data and artificial intelligence platforms.
[0059] In addition, the server 120 may also be a node server in the blockchain network.
[0060] The terminal processor 110 and the server 120 may establish a communication connection through a wireless network. The wireless network uses standard communication technology and / or protocols, and the network may be set to the Internet, or any other network, such as but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, or any combination of a wireless network, a private network, or a virtual private network. Moreover, the above-mentioned software and hardware entities may use the same communication connection mode or different communication connection modes, and this application does not impose any specific restrictions on this.
[0061] Of course, it is understandable that Figure 1 The implementation environment in the embodiment of the present application is only some optional application scenarios of the telephone state identification method provided in the embodiment of the present application, and the actual application is not fixed. Figure 1 The software and hardware environment shown is not specifically limited in this application.
[0062] like Figure 2 As shown, Figure 2 It is a flowchart of a method for identifying a telephone status provided in an embodiment of the present application, which specifically includes but is not limited to steps S100 to S300.
[0063] Step S100: Obtain circuit characteristic values of the monitoring line within the current sampling period.
[0064] In an embodiment of the present application, a sampling period refers to the length of time during which a processor samples circuit characteristic values of a monitoring circuit at certain time intervals, wherein the time length and the time interval between adjacent sampling periods can be set according to the actual usage scenario (for example, the time length can be set to 20 seconds, and the time interval can be set to 1 second), and the present application does not impose any specific restrictions on this.
[0065] Furthermore, the monitoring line refers to the connection line between the program-controlled telephone exchange and the telephone used by the user. The circuit characteristic value is the parameter describing the circuit characteristics and behavior in the monitoring line, such as current, voltage, etc., which can be collected in real time by electronic instruments such as high-speed ADC chips or sensors.
[0066] In practical applications, the circuit characteristic values of the monitoring lines obtained at each sampling time can be recorded in units of each sampling period, and marked according to the sampling time, and the records are stored in the server. For example, in a sampling period of 20 seconds, the circuit characteristic values of 20 groups of monitoring lines from the 1st second to the 20th second are recorded in units of each second as the circuit characteristic values of the sampling period of 20 seconds.
[0067] Step S200: Determine the telephone status of the telephone in the monitoring line within the current sampling period according to the circuit characteristic value.
[0068] In the embodiment of the present application, when the telephone is in different telephone states, its circuit characteristic value has different characteristics. Therefore, by performing a comprehensive analysis of the circuit characteristic value of the monitoring line obtained during each sampling cycle, the telephone state of the telephone in the monitoring line can be determined.
[0069] Specifically, as an optional implementation, the circuit characteristic value includes a current value and an AC level value; and determining the telephone state of a telephone in the monitoring line within the current sampling cycle time according to the circuit characteristic value includes:
[0070] When the current value of the monitoring line is less than or equal to the first threshold, determining that the telephone state of the telephone in the monitoring line within the current sampling period is on-hook;
[0071] When the current value of the monitoring line is greater than the second threshold value, and the time during which the AC level value of the monitoring line is greater than the third threshold value and less than the fourth threshold value satisfies the first preset time threshold value, determining that the telephone state of the telephone in the monitoring line within the current sampling cycle time is the off-hook dialing state;
[0072] When the current value of the monitoring line is greater than the second threshold value, and the number of times that the change value of the AC level value of the monitoring line within the current sampling cycle is greater than the fifth threshold value within adjacent sampling moments satisfies the sixth threshold value, it is determined that the telephone state of the telephone in the monitoring line within the current sampling cycle time is a busy tone state;
[0073] When the current value of the monitoring line is greater than the second threshold value, and the time during which the AC level value of the monitoring line is greater than the seventh threshold value satisfies the first preset time threshold value, determining that the telephone state of the telephone in the monitoring line within the current sampling cycle time is the hang-up tone state;
[0074] When the current value of the monitoring line is greater than the second threshold, and the time during which the AC level value of the monitoring line is less than the fifth threshold satisfies the first preset time threshold, it is determined that the telephone state of the telephone in the monitoring line within the current sampling cycle is an abnormal off-hook state.
[0075] In the present application example, the circuit characteristic values can be current values and AC level values. Both the current values and the AC level values can be collected by electronic instruments in a high-speed polling collection mode on the monitoring line, and the AC level value at each sampling moment is calculated. Combined with the loop current value of the monitoring line, a comprehensive analysis is performed to identify the telephone status.
[0076] For example, a high-speed ADC chip can be used to collect voltage on the monitoring line multiple times. For example, the line voltage value can be collected 10 times within 1 second, the maximum and minimum voltage values obtained from the 10 collection results can be determined, and the difference between the maximum and minimum voltage values can be obtained. The difference is the AC level value.
[0077] Of course, it can be understood that the above-mentioned AC level value collection methods are just some optional methods provided in the embodiments of the present application. The actual application is not fixed to the collection method of the high-speed ADC chip mentioned above, and the present application does not make any specific restrictions on this.
[0078] For example, please refer to Figure 3 , Figure 3 is a schematic diagram of a circuit characteristic value recording table provided in an embodiment of the present application, Figure 3 The circuit characteristic values are recorded in the table when the user fails to properly return the phone handle to its original position after completing a call, causing the phone to go into an abnormal off-hook state.
[0079] Among them, from the 1st second to the 5th second, the telephone is in the on-hook state. Since the telephone and the program-controlled switch are disconnected when hanging up, the circuit characteristic values collected by the monitoring line can determine that the current value is less than 5mA, and the AC level value is approximately 0V; from the 6th second to the 25th second, the user picks up the handset to talk, and a loop is formed between the telephone and the program-controlled switch at this time. The circuit characteristic values collected by the monitoring line can determine that the current value is greater than 10mA; from the 26th second to the 45th second, after the other end hangs up, the user does not put the telephone handset back to its original position correctly, and the telephone enters a busy tone state. The circuit characteristic values collected by the monitoring line can determine that the current value is greater than 10mA, and the AC level value frequently jumps, and the AC level value changes between adjacent samplings. The change value within a moment (for example, the change value of the AC level value from the 26th second to the 27th second is 0.37-0.08=0.29V) is greater than 0.1V for more than 10 times; from the 46th second to the 65th second, the phone enters the hang-up tone state, and the circuit characteristic values collected by the monitoring line can determine that the current value is greater than 10mA, the AC level value is greater than 0.5V, and the time when the AC level value is greater than 0.5V is greater than 15 seconds; from the 66th second to the 85th second, because the phone handle has not been correctly put back, the phone enters the abnormal off-hook state, and the circuit characteristic values collected by the monitoring line can determine that the current value is greater than 10mA, the AC level value is less than 0.1V, and the time when the AC level value is less than 0.1V is greater than 15 seconds.
[0080] For example, please refer to Figure 4 , Figure 4 is a schematic diagram of another circuit characteristic value recording table provided in an embodiment of the present application, Figure 4The circuit characteristic values are recorded when the user accidentally touches the telephone handle, causing the telephone handle to fall off and causing the telephone to go into an abnormal off-hook state.
[0081] Among them, from the 1st second to the 5th second, the telephone is in the on-hook state. Since the telephone and the program-controlled switch are disconnected when hanging up, the circuit characteristic values collected by the monitoring line can determine that the current value is less than 5mA, and the AC level value is approximately 0V; from the 6th second to the 25th second, the user accidentally touches the handle. At this time, a loop is formed between the telephone and the program-controlled switch, and the telephone enters the off-hook dialing state. The circuit characteristic values collected by the monitoring line can determine that the current value is greater than 10mA, and the time of 0.2V<AC level value<0.4V is greater than 15 seconds; from the 26th second to the 45th second, since the telephone handle is not correctly placed back to its original position, the telephone enters the busy tone state. The circuit characteristic values collected by the monitoring line can determine that the current value is greater than 10mA, and the AC level The value changes frequently, and the change value of the AC level value in adjacent sampling moments (for example, the change value of the AC level value from the 26th second to the 27th second is 0.3-0.02=0.28V) is greater than 0.1V for more than 10 times; from the 46th second to the 65th second, the phone enters the hang-up tone state, and the circuit characteristic values collected by the monitoring line can determine that the current value is greater than 10mA, the AC level value is greater than 0.5V, and the time when the AC level value is greater than 0.5V is greater than 15 seconds; from the 66th second to the 85th second, because the telephone handle has not been put back correctly, the phone enters the abnormal off-hook state, and the circuit characteristic values collected by the monitoring line can determine that the current value is greater than 10mA, the AC level value is less than 0.1V, and the time when the AC level value is less than 0.1V is greater than 15 seconds.
[0082] Therefore, combined with the above analysis, when the phone is in different phone states, the current value and the AC level value in the circuit characteristic value have different characteristics. For example, when the phone is in the on-hook state, the current value is always less than a threshold value, and when the phone is in the off-hook state, the current value is always greater than another threshold value.
[0083] Furthermore, in practical applications, according to a plurality of preset thresholds, based on the circuit characteristic values of the monitoring line collected in each sampling period, the telephone status of the telephone in the monitoring line can be determined.
[0084] Specifically, when the current value of the monitoring line is less than or equal to the first threshold value (for example, Figure 3 and Figure 4 For example, the first threshold value can be set to 5mA), it is determined that the telephone state of the telephone in the monitoring line within the current sampling period is the on-hook state; when the current value of the monitoring line is greater than the second threshold value, and the time when the AC level value of the monitoring line is greater than the third threshold value and less than the fourth threshold value meets the first preset time threshold value (for example, Figure 4 For example, the second threshold value can be set to 10mA, the third threshold value can be set to 0.2V, the fourth threshold value can be set to 0.4V, and the first preset time threshold value can be set to 15 seconds), it is determined that the telephone state of the telephone in the monitoring line within the current sampling cycle time is the off-hook dialing state; when the current value of the monitoring line is greater than the second threshold value, and the number of changes in the AC level value of the monitoring line within the current sampling cycle time within adjacent sampling moments is greater than the fifth threshold value, the sixth threshold value (for example, Figure 3 and Figure 4 For example, the fifth threshold value can be set to 0.1V, and the sixth threshold value can be set to 10 times), it is determined that the telephone state of the telephone in the monitoring line within the current sampling period is a busy state; when the current value of the monitoring line is greater than the second threshold value, and the time when the AC level value of the monitoring line is greater than the seventh threshold value satisfies the first preset time threshold (for example, Figure 3 and Figure 4 For example, the seventh threshold value can be set to 0.5V), it is determined that the phone state of the telephone in the monitoring line within the current sampling cycle is the hang-up tone state; when the current value of the monitoring line is greater than the second threshold value, and the time when the AC level value of the monitoring line is less than the fifth threshold value meets the first preset time threshold, it is determined that the phone state of the telephone in the monitoring line within the current sampling cycle is the abnormal off-hook state.
[0085] Of course, it is understandable that the threshold settings provided above are only some optional reference examples provided in the embodiments of the present application. The actual threshold settings are not fixed to the values given in the above embodiments, and the present application does not impose any specific restrictions on this.
[0086] Step S300: Determine the telephone state change trend of the telephone according to the telephone state of the telephone within a plurality of consecutive sampling periods, thereby determining off-hook warning information of the telephone.
[0087] In the embodiment of the present application, Figure 3 and Figure 4 For example, by setting the length of the sampling period to 20 seconds, that is, the 6th to 25th seconds is a sampling period, the 26th to 45th seconds is a sampling period, the 46th to 65th seconds is a sampling period, and the 66th to 85th seconds is a sampling period, the phone state of the telephone in each sampling period can be determined according to the circuit characteristic value in each sampling period, and the phone state change trend of the phone can be determined according to the phone state of the phone in multiple consecutive sampling periods.
[0088] For example, Figure 3For example, the phone states of a telephone within multiple consecutive sampling cycles are on-hook state, off-hook talk state, busy tone state, urging to hang up tone state, and abnormal off-hook state, so that the phone state change trend can be determined as from on-hook state to off-hook talk state, from off-hook talk state to busy tone state, from busy tone state to urging to hang up tone state, and from urging to hang up tone state to abnormal off-hook state.
[0089] For example, Figure 4 For example, the phone states of a telephone within multiple consecutive sampling cycles are on-hook state, off-hook dialing state, busy tone state, urging to hang up tone state, and abnormal off-hook state, so that the phone state change trend can be determined as from on-hook state to off-hook dialing state, from off-hook dialing state to busy tone state, from busy tone state to urging to hang up tone state, and from urging to hang up tone state to abnormal off-hook state.
[0090] Therefore, combined with the above analysis, it can be determined that before the abnormal off-hook state occurs, the telephone will successively appear busy tone state and reminder to hang up tone state, and then enter and maintain the abnormal off-hook state. Therefore, it can be further determined that the off-hook warning information is an abnormal off-hook state, and an alarm can be given through the alarm indicator light and alarm sound, so as to notify the maintenance personnel to handle it.
[0091] Specifically, as an optional implementation, please refer to Figure 5 , Figure 5 1 is a flow chart of determining off-hook warning information provided by an embodiment of the present application, wherein the method of determining the telephone state change trend of the telephone according to the telephone state of the telephone within a plurality of consecutive sampling cycles, thereby determining the off-hook warning information of the telephone, includes:
[0092] Determining a change trend of the telephone state of the telephone according to the telephone state of the telephone within a plurality of consecutive sampling periods;
[0093] When the telephone state change trend of the telephone satisfies the first change trend, determining the off-hook warning information of the telephone as abnormal off-hook;
[0094] When the telephone state change trend of the telephone does not meet the first change trend, determining the off-hook warning information of the telephone as no abnormal off-hook occurs;
[0095] The first change trend is a change from a busy tone state to an urging-to-hang-up tone state, and then a change from the urging-to-hang-up tone state to an abnormal off-hook state.
[0096] In the embodiments of the present application, Figure 3 and Figure 4, it can be determined that before the abnormal off-hook state occurs, the telephone will successively appear busy tone state and hanging-up tone state, and then enter and maintain the abnormal off-hook state. Therefore, the first change trend can be set to change from busy tone state to hanging-up tone state, and then from hanging-up tone state to abnormal off-hook state. When the telephone state change trend of the telephone meets the first change trend, it is determined that the telephone has an abnormal off-hook situation. If it is not handled in time, it may affect the incoming calls of the telephone, which may further affect the user experience. Therefore, the off-hook warning information of the telephone is determined as abnormal off-hook. Based on this, the buzzer and indicator LED lights configured on the hardware platform can be used to give warnings to notify maintenance personnel to handle it; when the telephone state change trend of the telephone does not meet the first change trend, it can be determined that the off-hook warning information of the telephone is that no abnormal off-hook occurs, and no relevant warning processing is required.
[0097] Therefore, the present application obtains the circuit characteristic value of the monitoring line in real time, and quickly identifies the phone status of the telephone by monitoring the changing characteristics of the current value and the AC level value. It determines whether the phone has abnormal off-hook phenomenon based on the changing trend of the phone status, and promptly gives an abnormal off-hook alarm to avoid the situation where the phone cannot make incoming calls, thereby effectively improving the user experience.
[0098] Further, as an optional implementation, please refer to Figure 6 , Figure 6 is a structural schematic diagram of a monitoring circuit provided in an embodiment of the present application, wherein the monitoring circuit comprises: a first resistor R1, a second resistor R2, a third resistor R3, and a voltage acquisition unit;
[0099] The first resistor R1 is connected to the internal line interface and the external line interface respectively;
[0100] The second resistor R2 is connected to one side of the first resistor R1 and one side of the voltage acquisition unit respectively;
[0101] The third resistor R3 is respectively connected to the other side of the first resistor R1 and the other side of the voltage acquisition unit;
[0102] The resistance of the second resistor R2 and the resistance of the third resistor R3 are both greater than the resistance of the first resistor R1.
[0103] In the embodiment of the present application, the AC level value can be directly obtained and calculated through the voltage acquisition unit, and the loop current value in the monitoring circuit can be quickly calculated based on the voltage difference between the two sides of the first resistor and the resistance value of the first resistor.
[0104] Further, as an optional implementation, the resistance of the first resistor is less than or equal to 10 ohms; the resistance of the second resistor and the resistance of the third resistor are both greater than or equal to 100,000 ohms.
[0105] That is to say, in the embodiment of the present application, a high-resistance resistor of not less than 100 kΩ is incorporated, and a low-resistance resistor of not more than 10 Ω is connected in series with the monitoring line. During the monitoring process, the call quality of the telephone's current service will not be affected.
[0106] For example, the impact of high-resistance resistors is analyzed. The telephone network call loop impedance is 600Ω. After the monitoring line is connected with a 100kΩ resistor, the impedance changes to 598.2Ω. The impedance change rate is only 0.25%, and the impact on the impedance characteristics can be ignored. The impact of low-resistance series connection is analyzed. According to the measured single-line resistance of 130Ω for a 1km communication line, a line model is constructed. When a 10Ω resistor is connected in series to the monitoring line, the line resistance changes by 7.7%, which is equivalent to extending the telephone line by 77m. According to the attenuation constant of 1.9dB / km for the double-line, the series connection resistor has little effect on the attenuation of the voice signal, which is no more than 0.15dB.
[0107] Therefore, combined with the above analysis, when the monitoring line provided in this application monitors the phone status of a telephone, the monitoring process will not affect the service quality of the telephone's active services, and can further timely monitor whether the telephone has an abnormal off-hook status.
[0108] In practical applications, please refer to Figure 7 , Figure 7 It is a structural schematic diagram of an installation and deployment of a monitoring line provided in an embodiment of the present application. The external line interface of the monitoring line is connected to a telephone, the internal line interface is connected to a program-controlled telephone exchange, and is communicated with a computer processor (for example, via SPI communication), and a buzzer, an alarm indicator light, a power interface, a status indicator light, a debugging serial port, and a reset button are provided at the computer processor. It is capable of online real-time monitoring of circuit characteristic values collected by the monitoring line between the telephone and the program-controlled telephone exchange, and real-time analysis of the telephone status of the telephone, so as to determine whether the telephone has an abnormal off-hook state of being off-hook for a long time, and the installation and deployment wiring of the monitoring line provided by the present application is convenient and fast, will not affect the services in use, and can realize real-time monitoring of the telephone status of the telephone.
[0109] Specifically, as an optional implementation, the method further includes:
[0110] In response to the triggered update instruction, the first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold, the sixth threshold, the seventh threshold and the first preset time threshold are updated.
[0111] It can be understood that the first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold, the sixth threshold, the seventh threshold and the first preset time threshold are not unchangeable after being pre-set, but multiple thresholds can be updated in real time by responding to triggered update instructions, thereby better meeting user usage needs.
[0112] It should be noted that the update instruction can be actively triggered by the user or by the processor itself, and this application does not make any specific limitation on this.
[0113] In an embodiment of the present application, update instructions may include different update instructions such as voice update instructions, text input update instructions entered through an input box, touch update instructions triggered by touch screen operation, selection update instructions triggered by drop-down menu selection, and update instructions selected by checking a check box, but are not limited to the above content.
[0114] Specifically, as an optional implementation, after determining the telephone state change trend of the telephone according to the telephone state of the telephone within a plurality of consecutive sampling cycles, thereby determining the off-hook warning information of the telephone, the method further includes:
[0115] After the preset sampling interval, the step of obtaining the circuit characteristic value of the monitoring line within the current sampling period is returned to be executed until the off-hook warning information of the telephone is determined.
[0116] In an embodiment of the present application, when the off-hook warning information of the telephone is determined according to the telephone state change trend, it is possible to return to the step of obtaining the circuit characteristic value of the monitoring line within the current sampling cycle time after a preset sampling interval, that is, to obtain the circuit characteristic value of the monitoring line within the next sampling cycle time until the off-hook warning information of the telephone is determined. This allows for repeated determination of the real-time telephone state of the telephone, thereby determining whether the telephone has an abnormal off-hook state, which helps to give a timely warning of abnormal off-hook.
[0117] Below, in conjunction with the specific application implementation process, the telephone state identification method provided in this application is described in detail and explained:
[0118] In an embodiment of the present application, a phone state recognition method is provided, which can be applied to the phone state recognition scenario of a telephone. By detecting and analyzing the circuit characteristic values of the line, the phone state change trend of the phone is determined, thereby quickly identifying whether the phone has an abnormal off-hook state of being off-hook for a long time, which helps to give an off-hook warning prompt in time, avoid the situation where the phone cannot make incoming calls, and effectively improve the user experience.
[0119] Specifically, the circuit characteristic value of the monitoring line obtained at each sampling moment can be recorded in units of each sampling cycle, and marked according to the sampling moment, and recorded and stored in the server. Among them, the circuit characteristic value can be a current value and an AC level value, and both the current value and the AC level value can be collected by an electronic instrument in a high-speed polling collection mode on the monitoring line, and the AC level value at each sampling moment is calculated, combined with the loop current value of the monitoring line, and a comprehensive analysis is performed to identify the telephone state of the telephone.
[0120] Furthermore, in practical applications, according to a plurality of preset thresholds, based on the circuit characteristic values of the monitoring line collected in each sampling period, the telephone state of the telephone in the monitoring line can be determined. For example, when the current value of the monitoring line is less than or equal to the first threshold (for example, Figure 3 and Figure 4 For example, the first threshold value can be set to 5mA), it is determined that the telephone state of the telephone in the monitoring line within the current sampling period is the on-hook state; when the current value of the monitoring line is greater than the second threshold value, and the time when the AC level value of the monitoring line is greater than the third threshold value and less than the fourth threshold value meets the first preset time threshold value (for example, Figure 4 For example, the second threshold value can be set to 10mA, the third threshold value can be set to 0.2V, the fourth threshold value can be set to 0.4V, and the first preset time threshold value can be set to 15 seconds), it is determined that the telephone state of the telephone in the monitoring line within the current sampling cycle time is the off-hook dialing state; when the current value of the monitoring line is greater than the second threshold value, and the number of changes in the AC level value of the monitoring line within the current sampling cycle time within adjacent sampling moments is greater than the fifth threshold value, the sixth threshold value (for example, Figure 3 and Figure 4 For example, the fifth threshold value can be set to 0.1V, and the sixth threshold value can be set to 10 times), it is determined that the telephone state of the telephone in the monitoring line within the current sampling period is a busy state; when the current value of the monitoring line is greater than the second threshold value, and the time when the AC level value of the monitoring line is greater than the seventh threshold value satisfies the first preset time threshold (for example, Figure 3 and Figure 4 For example, the seventh threshold value can be set to 0.5V), it is determined that the phone state of the telephone in the monitoring line within the current sampling cycle is the hang-up tone state; when the current value of the monitoring line is greater than the second threshold value, and the time when the AC level value of the monitoring line is less than the fifth threshold value meets the first preset time threshold, it is determined that the phone state of the telephone in the monitoring line within the current sampling cycle is the abnormal off-hook state.
[0121] Furthermore, it can be determined that before the abnormal off-hook state occurs, the telephone will successively appear a busy tone state and a urging tone state, and then enter and maintain the abnormal off-hook state. Therefore, the first change trend can be set to change from a busy tone state to a urging tone state, and then from a urging tone state to an abnormal off-hook state. When the telephone state change trend of the telephone meets the first change trend, it is determined that the telephone has an abnormal off-hook situation. If it is not handled in time, it may affect the incoming calls of the telephone, which may further affect the user experience. Therefore, the off-hook warning information of the telephone is determined to be an abnormal off-hook situation. Based on this, a warning can be given through the buzzer and indicator LED lights configured on the hardware platform to notify the maintenance personnel to handle it. When the telephone state change trend of the telephone does not meet the first change trend, it can be determined that the off-hook warning information of the telephone is that no abnormal off-hook situation has occurred, and no relevant warning processing is required.
[0122] Optionally, the monitoring circuit includes: a first resistor, a second resistor, a third resistor, and a voltage acquisition unit, through which the AC level value can be directly obtained and calculated, and the loop current value in the monitoring circuit can be quickly calculated according to the voltage difference between the two sides of the first resistor and the resistance value of the first resistor. Among them, a high-resistance resistor of not less than 100kΩ is incorporated, and a low-resistance resistor of not more than 10Ω is used in series to connect the monitoring circuit, and during the monitoring process, the call quality of the service in use by the telephone will not be affected.
[0123] Finally, multiple thresholds can be updated in real time by responding to the triggered update instructions, thereby better meeting the user's usage needs, and after a pre-set sampling interval, return to execute the step of obtaining the circuit characteristic value of the monitoring line within the current sampling cycle time, that is, obtain the circuit characteristic value of the monitoring line within the next sampling cycle time until the off-hook warning information of the phone is determined. This can realize the repeated determination of the real-time phone status of the phone, thereby determining whether the phone has an abnormal off-hook state, which helps to give a timely warning prompt of abnormal off-hook.
