Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0054] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time.

[0055] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0056] Embodiment 1

[0057] See also Figure 1 , Figure 1 A flowchart of a method for monitoring the internal environment of a cable box provided in a first embodiment of the present invention is shown. The cable box internal environment monitoring device can be implemented by software and / or hardware. The method specifically includes steps S01 to S09.

[0058] Step S01, obtaining environmental data uploaded by a cable box environment monitoring point, wherein the environmental data at least includes a cable box external temperature value, a cable box internal temperature value, and a cable box internal condensation impedance value.

[0059] Specifically, environmental data may also include cable box vibration data, cable box tilt data, cable box abnormal unpacking data or other environmental data that may affect the cable signal. Among them, the cable box vibration data may be used to monitor the vibration intensity of the cable box, ensure the stability inside the cable box, and prevent problems such as poor contact of internal cables and terminal damage due to excessive vibration. The cable box tilt data may be used to monitor whether the cable box falls over, and the cable box abnormal unpacking data may be used to monitor whether the cable box is in an abnormally opened state, to avoid malicious damage to the cable box and internal cables.

[0060] Step S02: acquiring a condensation temperature value according to the external temperature value of the cable box, and determining whether the condensation temperature value is less than the internal temperature value of the cable box.

[0061] Specifically, relative humidity is defined as the ratio of the absolute humidity in the air to the saturated absolute humidity at the same temperature and pressure. In specific studies, through large-sample statistical analysis, it is found that as the ambient temperature and humidity data change, the corresponding dew point temperature is also changing. For example, as the ambient temperature and humidity increase, the corresponding dew point temperature is also rising. In specific implementation, it is necessary to enter the temperature value outside the cable box into the mapping table, and then the condensation temperature value under the current condensation state can be determined by looking up the table. It can be understood that when the temperature value inside the cable box reaches the condensation temperature value, condensation will occur.

[0062] When it is determined that the condensation temperature value is less than the temperature value inside the cable box, that is, no condensation is generated, S03 is executed.

[0063] Step S03, calculating the temperature difference between the condensation temperature value and the temperature value inside the cable box.

[0064] It should be noted that the calculation method is to subtract the condensation temperature value from the internal temperature value of the cable box, wherein the closer the internal temperature value of the cable box is to the condensation temperature value, the easier it is to generate condensation.

[0065] Step S04, determining whether the temperature difference is less than or equal to a temperature warning threshold.

[0066] In this embodiment, the temperature warning threshold is set to 10. When it is determined whether the temperature difference is less than or equal to the temperature warning threshold value is less than or equal to 10, it means that the temperature value inside the cable box is close to the condensation temperature value at which condensation will occur in the cable box, and attention needs to be paid, then S05 is executed.

[0067] Step S05, determining whether the condensation impedance value inside the cable box is greater than an impedance warning threshold.

[0068] Specifically, the impedance warning threshold is set to 20KΩ. When it is determined that the condensation impedance value inside the cable box is greater than 20KΩ, S06 is executed; when it is determined that the condensation impedance value inside the cable box is not greater than the warning threshold, it means that the environmental data in the current box is normal, and no action is taken to continue monitoring.

[0069] Step S06, issuing an early warning message indicating that the environmental data uploaded by the cable box environmental monitoring point is abnormal, and continuing to obtain the environmental data.

[0070] It is understandable that the issuance of a warning message means that there is a high possibility of condensation or humidity in the future. When maintenance personnel receive the warning message, they can deploy in advance and pay special attention.

[0071] Step S07, determining whether the condensation temperature value obtained next time is greater than or equal to the cable box internal temperature value obtained next time.

[0072] It should be noted that, during the continuous monitoring process, when it is determined that the condensation temperature value obtained next time is greater than or equal to the cable box internal temperature value obtained next time, condensation has occurred, and S08 is executed.

[0073] Step S08, determining whether the condensation impedance value obtained next time is greater than an impedance alarm threshold.

[0074] Specifically, in order to further understand the state of condensation, the size of the condensation impedance value is judged. In this embodiment, the impedance alarm threshold is set to 100KΩ, that is, when it is judged that the condensation impedance value obtained next time is greater than 100KΩ, it means that the condensation inside the cable box is already serious, then execute S09.

[0075] Step S09, issuing an alarm prompt message, wherein the alarm prompt message is used to notify relevant personnel that condensation occurs in the cable box.

[0076] In summary, the method for monitoring the internal environment of a cable box in the above-mentioned embodiment of the present invention can effectively understand the current environmental conditions in the box by obtaining environmental data uploaded by a cable box environmental monitoring point, wherein the environmental data at least includes the external temperature value of the cable box, the internal temperature value of the cable box, and the condensation impedance value of the cable box. The temperature value under the corresponding condensation state is obtained through the external temperature value of the cable box, and the internal temperature value of the cable box is compared with the condensation temperature value. It can effectively determine whether the inside of the cable box is damp or water has entered. Combined with the condensation impedance value, a judgment can be made to understand the condensation situation. When it is judged that the condensation impedance value is greater than the impedance alarm threshold, an alarm prompt information is issued, so that relevant personnel can be notified in time to perform maintenance on the corresponding cable box, and there is no need to rely on manual regular unpacking and inspection for maintenance.

[0077] Embodiment 2

[0078] A second embodiment of the present invention provides a method for monitoring the internal environment of a cable box. The cable box internal environment monitoring device can be implemented by software and / or hardware. The method specifically includes steps S11 to S25.

[0079] Step S11, obtaining environmental data uploaded by a cable box environment monitoring point, wherein the environmental data at least includes a cable box external temperature value, a cable box internal temperature value, and a cable box internal condensation impedance value.

[0080] In this embodiment, the environmental data specifically include the external temperature value of the cable box, the internal temperature value of the cable box, and the condensation impedance value inside the cable box, and the above three types of environmental data are updated every 1 minute.

[0081] Step S12, determining whether the condensation impedance value inside the cable box is less than an impedance alarm threshold.

[0082] The impedance alarm threshold is 100KΩ, that is, when it is determined that the condensation impedance value inside the cable box is less than 100KΩ, S13 is executed; when it is determined that the condensation impedance value inside the cable box is greater than or equal to 100K, an alarm prompt message is directly issued without the need for further judgment.

[0083] Step S13, obtaining the condensation impedance value at the current moment and the condensation impedance value 6 minutes after the current moment.

[0084] It can be understood that the condensation impedance value will be obtained every 1 minute, and the condensation impedance value will be read every 6 minutes for the next step of processing.

[0085] Step S14, determining whether a change between the condensation impedance value at the current moment and the condensation impedance value 6 minutes later based on the current moment is less than a change threshold.

[0086] Since the condensation impedance value is obtained every 6 minutes, when it is determined that the change between the condensation impedance value at the current moment and the condensation impedance value 6 minutes after the current moment is less than the change threshold, S15 is executed; when it is determined that the change between the condensation impedance value at the current moment and the condensation impedance value 6 minutes after the current moment is greater than or equal to the change threshold, it means that serious water ingress may occur within these 6 minutes, and an alarm prompt message is issued.

[0087] Step S15, obtaining a condensation temperature value according to the external temperature value of the cable box, and determining whether the condensation temperature value is less than the internal temperature value of the cable box.

[0088] In this embodiment, the mapping table is specifically shown in Table 1 below:

[0089] Table 1

[0090]

[0091] It can be understood that the correspondence between the temperature value and the condensation temperature value under the corresponding condensation state is shown in the table above. According to this correspondence, a relevant curve has been fitted and input into the server as a program. After the mapping relationship table is established, the obtained external temperature value of the cable box is input into the program to obtain the corresponding relative humidity value, and then the corresponding condensation temperature value is obtained according to the relative humidity value. The condensation temperature value refers to the theoretical temperature value when condensation occurs inside the cable box.

[0092] Step S16, calculating the temperature difference between the condensation temperature value and the temperature value inside the cable box

[0093] Step S17, determining whether the temperature difference is less than or equal to a temperature warning threshold.

[0094] Step S18, determining whether the condensation impedance value inside the cable box is greater than an impedance warning threshold.

[0095] Step S19, issuing an early warning message indicating that the environmental data uploaded by the cable box environmental monitoring point is abnormal, and continuing to obtain the environmental data.

[0096] Step S20, determining whether the condensation temperature value obtained next time is greater than or equal to the cable box internal temperature value obtained next time.

[0097] Step S21, determining whether the condensation impedance value obtained next time is greater than an impedance alarm threshold.

[0098] Step S22, issuing an alarm prompt message, wherein the alarm prompt message is used to notify relevant personnel that condensation occurs in the cable box.

[0099] Step S23, obtaining the identity information of the cable box environment monitoring point, and obtaining the geographical location information of the cable box environment monitoring point according to the identity information.

[0100] Specifically, each cable box environment monitoring point has its unique identity information, namely, an IP address, through which the geographical location information of the cable box environment monitoring point can be obtained, and the geographical location information at least includes the longitude and latitude of the cable box environment monitoring point.

[0101] Step S24, acquiring meteorological data from the time when the early warning prompt information is issued to the time when the alarm prompt information is issued according to the geographical location information, wherein the meteorological data at least includes temperature data.

[0102] Step S25, establishing a prediction model according to the temperature data, wherein the prediction model is used to predict changes in condensation state with temperature.

[0103] It is understandable that the occurrence of condensation is also affected by the weather, especially in mountainous areas, where the temperature difference between day and night is large and the air humidity is high, condensation and humidity are very likely to occur. In this embodiment, the longitude and latitude of the cable box environmental monitoring point are associated with the corresponding weather temperature, and the temperature data from the time the early warning prompt information is issued to the time the alarm prompt information is issued is extracted. By establishing a prediction model for the temperature data, that is, when there are similar weather temperature changes in the future and match the historical data, the condensation situation of the cable box environmental monitoring point can be predicted, providing relevant reference for maintenance personnel.
