Fig. 8 shows the flow chart that safety utilization of electric power controlling terminal 131 cuts off power supply line's method 405.Safety utilization of electric power control
Terminal cut off power supply line's method 405 the following steps are included:
Step 801, safety utilization of electric power controlling terminal reads the numerical value of phase line current.Safety utilization of electric power controlling terminal contains phase line
Current sensor and voltage and current Acquisition Circuit, therefore safety utilization of electric power controlling terminal can be with the number of real-time measurement phase line current
Value.
Step 802, if the virtual value of phase line current is greater than zero, step 803 is executed, it is no to then follow the steps 807.It is negative when having
When load is in operating status or standby mode, the virtual value of phase line current is greater than zero, and otherwise the virtual value of phase line current is equal to
Zero.
Step 803, safety utilization of electric power controlling terminal sends the order of " cutting power supply line " to intelligent socket.
Step 805, safety utilization of electric power controlling terminal waits for a period of time.The mesh that safety utilization of electric power controlling terminal waits for a period of time
, it is that the load (such as computer) that those cannot directly be cut off the power has time enough shutdown.Safety utilization of electric power controlling terminal
The time of waiting is determined by pre-set numerical value.There are also other embodiments, for example, intelligent socket cuts off power supply line
Afterwards, the message of " power supply line has been turned off " is sent to safety utilization of electric power controlling terminal, on this basis, safety utilization of electric power controlling terminal can
The case where to understand intelligent socket cutting power supply line, and then judge that safety utilization of electric power controlling terminal can cut off power supply line.
Step 806, if someone terminates the process of intelligent socket cutting power supply line, step 808 is executed, is otherwise executed
Step 807.When intelligent socket receives the order of " cutting power supply line ", it passes through loudspeaker first or buzzer broadcasting mentions
Show sound, prompt the people using load, intelligent socket will cut off power supply line.If load is used in someone at this time, can
By the way that by the " Cancel " button on intelligent socket, stop intelligent socket cuts off the process of power supply line.When someone terminates intelligence
When the process of energy socket cutting power supply line, intelligent socket can send message to safety utilization of electric power controlling terminal, notify its intelligence
The process of socket cutting power supply line is terminated.
Step 807, the electronic switch in safety utilization of electric power controlling terminal cuts off power supply line.
Step 808, the execution of ending method 405.

The virtual value of line current is greater than zero, illustrates have load to be in operating status or standby mode, otherwise illustrates all loads all
It has been switched off.
Step 903, intelligent socket plays one section of prompt tone, reminds the people using load, and intelligent socket will cut off power supply
Route.It in this course, then can be by being inserted by intelligence if someone needs to continue to use load in office office work
The " Cancel " button on seat, stop intelligent socket cut off the process of power supply line.
Step 904, if the process of intelligent socket cutting power supply line is terminated, step 905 is executed, it is no to then follow the steps
906。
Step 905, intelligent socket sends " process of intelligent socket cutting power supply is terminated " to safety utilization of electric power controlling terminal
Message, then execute step 912.Intelligent socket sends the " process of intelligent socket cutting power supply to safety utilization of electric power controlling terminal
It is terminated " purpose of message, be notice safety utilization of electric power controlling terminal: someone is working in office, some intelligent socket is also not
It can cutting power supply.
Step 906, intelligent socket sends query messages to load closedown controller, obtains the status message of load.As a result
There are three types of possible: (1) at the appointed time, intelligent socket does not receive the response message of load closedown controller, and explanation does not have
There is the load that cannot directly cut off power supply to be connected on intelligent socket, intelligent socket can directly cut off power supply；It (2) cannot be direct
The load of cutting power supply all has been switched off, and intelligent socket can directly cut off power supply；(3) at the load that cannot directly cut off the power
In operating status or standby mode, intelligent socket cannot directly cut off power supply.
Step 907, if intelligent socket can directly cut off power supply, step 911 is executed, it is no to then follow the steps 908.
Step 908, intelligent socket sends the order of " closing load " to load closedown controller.
Step 910, intelligent socket waits load shutdown.In this course, load closedown controller can be by general
The state of I/O interface real-time monitoring load just sends disappearing for " load having been shut down " to intelligent socket once discovery load has been shut down
Breath.
Step 911, the electronic switch in intelligent socket cuts off power supply line.Once those cannot directly close the negative of power supply
Load has all been shut down, and intelligent socket can cut off power supply line.
Step 912, the execution of end step 804.
Figure 10 shows the flow chart that load closedown controller closes carrying method 909.It is negative to load closedown controller closing
Support method 909 the following steps are included:
Step 1001, if load is in standby mode, step 1002 is executed, it is no to then follow the steps 1004.
Step 1002, by general purpose I/O Interface, closedown controller is loaded to load and sends control signal, is detached from load
Standby mode.For example, load closedown controller can send control signal to load by USB interface or RS-232 interface, make
Load is detached from standby mode.
Step 1003, load closedown controller waits load to be detached from standby mode.Load is waited to be switched to by standby mode
Normal operating condition.
Step 1004, it by general purpose I/O Interface, loads closedown controller and is sent to resident control program in the load
The order of " closing load ".
Step 1005, load closedown controller waits load shutdown.In this course, load closedown controller can lead to
General purpose I/O Interface real-time detection load state is crossed, for example passes through the voltage value on the power supply line in USB interface, it can be determined that
Whether load has been switched off.
Step 1006, load closedown controller sends " load has been shut down " message to intelligent socket.
