In another aspect, the externally configured information collector C1 may be configured with a main switch of a house to measure the total power consumption of the house.
The first information 111 may be temporarily stored in the memory of the local server 11. When the local server 11 connects to the first server 12 via a network with wire or wirelessly, the first information 111 collected by the information collectors C1-Cn would be compiled and uploaded to the first server 12 in a predetermined time interval. Particularly, the predetermined time interval may be set by the user 10 according to the needs of the user 10.
In an embodiment, the first information 111 collected by the information collectors C1-Cn would be uploaded to the first server 12 in real-time, that is, immediately. In addition, the user 10 may log in the account via mobile devices or Internet to check the real-time status and using history of the electronic devices D1-Dn.
Furthermore, at least one second information 121 may be obtained by analyzing the at least one first information 111 by the first server 12. In an embodiment, the at least one second information 121 may comprise an actual mean time between failures (MTBF), a malfunction time, a malfunction frequency, a frequent malfunctioned module and a working period, total working hours and working status records of the electronic device D2 when the information collector C2 is built-in to the electronic device D2.

Referring to FIG. 3, after registering the electronic devices D1 to the personal account of the user 10, the first server 12 or the local server 11 may automatically write back a temporary safe interruption value (not shown) obtained by analyzing a predetermined number of times of the working current or voltage of the electronic device so that the safe power switch C11 is capable of cutting the power supply of the electronic device D1 to protect the electronic device D1. Preferably, the predetermined number of times may be ten times to dozens of times. The collection and analysis of the working current or voltage of the electronic device may be started from the first working time of the information collector or from resetting the information collector after changing the connected electronic device. However, the safe interruption value 122 may be varied due to variations and interference of the environment around the electronic device D1 and the voltage used therein. Thus, when the information collector C1 starts working, the first server 12 may collect the first information 111, such as current consumption, ambient humidity and ambient temperature, of the electronic device D1 within the first few weeks of operation so as to calculate the mean value of the working current or voltage. Accordingly, the mean value of the working current or voltage may be written back to the safe power switch C11 connected to the electronic device D1 by the first server 12 to be the safe interruption value 122, as a new safe protection booting mechanism.
Alternatively, the information collector C1 may connect to the first server 12 to search for the safe interruption value 122 of the electronic device D1 with reference to the predetermined information 101, such as a brand, a model name or a serial number of the electronic device D1, registered in the personal account. When corresponding safe interruption value 122 of the electronic device D1 is not found in the first server 12, the safe power switch C11 would applied the temporary safe interruption value 122 to be the safe interruption value 122 of the electronic device D1. In an embodiment, the user 10 may manually set up the safe interruption value 122 as well. However, the safe interruption value 122 may not exceed the rated current determined by the manufacturer of the electronic device D1. If the safe interruption value 122 is higher than the rated current set by the manufacturer, the rated current is written back to the safe power switch C11 as a substituted safe interruption value 122 by the first server 12.
Referring to FIG. 4, in an embodiment, when the electronic device D1 are under abnormal working status, the first server 12 may send a message 125 of an alarm to warn the user 10 via APP of mobile devices, SMS messages or emails. Wherein, the abnormal conditions may comprise that the temperature of the electronic device D1 exceeds a safe working temperature and turn-on or turn-off of the electronic device D1 at non-predetermined time etc. Furthermore, when the working current or voltage of the electronic device D1 surpassing a safe warning value, the local server 11 or the first server 12 may also send the message 125 to warn the user of cutting off the power supply of the electronic device D1 to avoid the working current or voltage exceeding the safe interruption value 122. Preferably, the safe warning value is calculated by the average of a normal maximum working current or voltage value of the electronic device D1 and the safe interruption value 122. More specifically, the normal maximum working current or voltage value is obtained by analyzing the working current or voltage of the electronic device D1 for a predetermined time under normal usage. In addition, when the user declining to cut off the power supply of the electronic device D1 when receiving the warning message, the normal maximum working current or voltage value is automatically elevated by the local server 11 or the first server 12 in order to elevate the safe warning value, namely, elevating the threshold of warning.
The user 10 may log in the personal account to check the alarm or the current status of the electronic devices D1-Dn remotely via a mobile device or a web browser. Additionally, the user may further check power consumption and a working history of the electronic devices D1-Dn. When necessary, the user 10 may log in the account to control the information collectors C1-Cn and further turn on safe power switches C11-Cn1 so that the power supply of the electronic devices D1-Dn may be cut off. In another embodiment, when the electronic devices D1-Dn are abnormally used with safety concern, the safe power switch C11-Cn1 of the information collectors C1-Cn or the first server 12 may cut off the power supply of the electronic devices D1-Dn in response to that a working current or voltage surpasses the safe interruption value 122 or the rated current. Contrarily, the first server 12 may automatically provide the user with an analysis report. Specifically, the analysis report may comprise total working hours, a working period, a working frequency, power consumption and variations of temperature and humidity of one individual electronic device D1 or all of the electronic devices D1-Dn. Even more, the first server 12 may provide an analysis report of the individual modules of the electronic device D2 when the information collector C2 of the electronic device are built-in.
Referring to FIG. 5, the method in accordance with an embodiment of the present invention may improve the quality of service and reduce the consumption of energy and human labor. The user 10 may check the current consumption, working history and current status of each one of the electronic devices D1-Dn via APP of a mobile device or Internet. In addition, the total power consumption of the individual electronic device D1 or all of the electronic devices D1-Dn in a period of time may be calculated periodically so as to be a parameter for saving energy or adjusting the time of using the electronic devices D1-Dn. The first server 12 may analyze working period of individual electronic device D1 in accordance with the parameter. The first server 12 may write back and adjust a setting of working period of the information collector C1-Cn so as to turn on the power in advance or delay the turn off process. As a result, the power consumption of the electronic devices D1-Dn may be reduced when the electronic devices D1-Dn are not in use or are in a standby mode.
When the time approaches the warranty expiration date, the first server 12 may automatically notify the user 10 by the local server 11 or the first server 12 via messages 125 in a predetermined time ahead of the warranty expiration date for reminding the user that the warranty expiration date is due. On the other hand, the first server 12 may calculate a fee of extending warranty for providing a maintenance service without a manufacturer of the electronic devices D1-Dn after a warranty expiration date, and query the user for extending the warranty expiration date by the local server 11 or the first server 12. That is, the first server 12 may automatically send a quotation 124 with a fee for extending the warranty so that the waste of manpower, and the time of communicating between the user and the manufacturer may be reduced.
In an embodiment, when a working current or voltage of the electronic devices D1, D2 exceed a normal range recorded and determined by the local server 11 or the first server 12, the local server 11 or the first server 12 may determine the electronic device D1 as a malfunctioned electronic device according to the externally configured information collector C1.
Specifically, when the information collector C2 is built-in to the electronic device D2, the local server 11 or the first server 12 may further determine a malfunction in the internal modules of the electronic device D2. In response to the malfunction, the information collector C1 automatically sends a notification to the user or the first server 12 through the local server 11 to notify the user. Subsequently, the first server 12 would notify the second server S1 to automatically generate a quotation for maintaining the electronic devices D1, D2 and provide the quotation to the local server 11 via the first server 12. When the user decline to maintain the malfunctioned electronic device, the first server 12 would demonstrate other electronic device with similar function to the user so that the user may directly purchase a new electronic device.
In an embodiment, in case of that the malfunctioned electronic device D2 is within the period of warranty, the first server 12 would send a notification 123 to notify the user and the customer service department of the manufacturer, i.e. the second server S2, according to the malfunctioned module and maintenance chart reported by the information collector C2. When the user replies the actual status of the malfunction with an approval for the maintenance, the first server 12 may notify the customer service department of the manufacturer to prepare the spare parts for the malfunctioned module. In addition, the customer service department of the manufacturer may send maintenance staff or the spare parts to the user 10 according to the maintenance chart replied by the user 10 to maintain the malfunctioned module. Thus, the human labor and time for the communication between the user and maintenance staff may be saved.
In another embodiment, in case of that the warranty of the malfunctioned electronic device D2 is expired, the first server 12 would send a notification 123 to notify the user and the customer service department of the manufacturer, i.e. the second server S2, according to the malfunctioned module and maintenance chart reported by the information collector C2. When the user replies the actual status of the malfunction, an approval for the maintenance and an agreement to the terms of payment, the first server 12 may notify the customer service department of the manufacturer to prepare the spare parts for the malfunctioned module. In addition, the customer service department of the manufacturer may send maintenance staff or the spare parts to the user according to the maintenance chart replied by the user to maintain the malfunctioned module. Thus, the human labor and time for the communication between the user and customer service personnel may be saved as well.
