specifically, the above transmission module is a wireless transmission module for performing signal connection, which protector is triggered can be determined according to state information of the hybrid protector, the first type protector and the second type protector, the abnormal value is determined according to the abnormal number of the terminals, and when the ratio of the abnormal number of the terminals to the total number of the terminals is less than or equal to a second threshold value, the initial determination is that the abnormal number of the terminals is caused by the hybrid protector and the first second protector, which is exemplary: the second threshold is 2/5, step S42 is further executed to further determine whether the terminal meets the restarting condition to determine whether the terminal is damaged, and when the ratio of the number of abnormal terminals to the total number of terminals is greater than the second threshold, it may be that the power supply is abnormal, so that the output needs to be stopped in time to prevent the terminal from being damaged.
The step S44: and judging which of the mixed protector or the first type protector and the second type protector is abnormal, and judging the type of the abnormality.
Specifically, which one of the abnormality has occurred is determined by the state of the hybrid protector or the first type protector, the second type protector, and the abnormality types include surge, leakage, and the like.
Further, the step S44 includes: when the type of the abnormality is electricity leakage, the main power supply is disconnected, the control unit and the transmission module are powered by a battery, the electricity leakage information is transmitted to the server or the user side, when the abnormality is only electricity surge, the control unit judges the position of the electricity surge based on the state information of the hybrid protector, the first type protector and the second type protector, if the hybrid protector and the first type protector are abnormal in the electricity surge, the main power supply is disconnected, if the electricity surge is only generated in the main power supply or the channel control unit, the main power supply and the channel control unit are reset after a first preset time interval, and the control unit resets the main power supply and the channel control unit and enters restarting based on a built-in reset program; and in a second preset time after restarting, if the same type of abnormality occurs again, the main power supply is disconnected, and meanwhile, a battery is used for supplying power to the control unit and the transmission module, so that the information transmission server or the user side cannot be recovered due to surge.
Specifically, in the hybrid protector or at least one of the first type protector and the second type protector is abnormal due to electric leakage, because the hazard of electric leakage is relatively large and the property is relatively bad, the main power supply needs to be disconnected, the electric leakage position is isolated, devices in a circuit are prevented from being broken down, when the main power supply is disconnected, the control unit and the transmission module are powered off, information cannot be continuously transmitted, the electric leakage information transmission needs to be completed through battery power, when the abnormality in the protector does not include electric leakage, the abnormality is considered to be surge, the surge has the characteristic of non-persistence, reset is performed after a predetermined time interval, the first predetermined time can be 10 seconds, whether the power supply needs to be switched or not is determined by detecting whether the surge occurs again, and when the power supply appears again, the main power supply is disconnected, the safety of the power source of the whole channel is ensured, and the safety of the terminal is ensured.
Further, the first detection result is a surge and/or leakage.
Further, when it is determined in the step S44 that the types of abnormalities occurring in the hybrid protector and the first-type protector and the second-type protector are different, step S45 is executed: resetting after a preset time interval, wherein the control unit resets the main power supply and the channel control unit based on a built-in reset program and enters a restarting state; and in a preset time after the reset, if the same type of abnormality occurs again, the main power supply is disconnected, and meanwhile, a battery is used for supplying power to the control unit and the transmission module, so that the main power supply is in surge so as to lead the information transmission server or the user side not to be recovered.
Specifically, if the types of abnormalities occurring in the hybrid protector and the first type protector and the second type protector are different, for example, the hybrid protector generates surge, the second type protector generates leakage, and it is possible that the surge causes the channel control unit to generate transient leakage, and the leakage is possible to recover after the surge is released, that is, the leakage is no longer generated, reset and restart after a predetermined interval time, for example, 10s, and within a predetermined time, for example, 10 minutes, and detect whether an abnormality occurs again, for example, surge, if the abnormality occurs again, the main power supply is disconnected, if the abnormality occurs again, normal operation can be continued, and the problem that the system cannot continue to operate even if the abnormality disappears accidentally is avoided.
Further, when the control unit monitors that the first state detection module and the second state detection unit are abnormal in the same type, the control unit controls the channel control unit to suspend multi-channel output, and when the second state detection unit is abnormal and the first state detection module is not abnormal, the switching unit performs first switching on a channel corresponding to the abnormal terminal, and the first switching enables the channel corresponding to the abnormal terminal to be connected to a charging channel and charges a battery.
Specifically, when the control unit monitors that the first state detection module and the second state detection unit have the same type of abnormality, it is possible that the channel control unit has an abnormality, the abnormality of the terminal is possibly caused by the abnormality of the channel control unit, so that the output of the multiple channels needs to be suspended, and when the second state detection unit has an abnormality and the first state detection module has no abnormality, it is possible that the terminal has an abnormality, so that the output channel corresponding to the abnormal terminal charges the battery, and the power source resource is reasonably used.
