Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.
Fig. 1 is a schematic diagram of an embodiment of a standby power output control method for a sleep-type intelligent power distribution terminal. The present embodiment includes the following steps:
s100, the intelligent power distribution terminal detects whether the main line loses power or not to obtain a detection result. Of course, the detection result may include that the main line is powered off, or the main line is not powered off, that is, the power supply of the main line is normally connected. Obviously, if the main line power supply is normally connected, the whole intelligent power distribution terminal can normally operate without additional operation. The following description focuses on the handling of abnormal situations in which the normal operation of the intelligent power distribution terminal is affected due to power loss of a main line and other reasons.
It should be noted here that the main line power supply of the intelligent power distribution terminal includes an ac power supply, and also includes other accessed dc power supplies, and all the accessed power supplies capable of ensuring normal power distribution of the intelligent power distribution terminal are available. In addition, as for the "intelligent" power distribution terminal, the intelligence here means that, with the popularization of computer technology, the power distribution terminal adopts some preferential power distribution in the power distribution process, and performs different power and current distribution in different periods, which are all intelligent power distribution, and the power distribution terminal with the function is called as an intelligent power distribution terminal. Certainly, after the control of the power distribution terminal to be described in this embodiment on the power loss mode of the main line is added, the intelligence of the intelligent power distribution terminal is stronger.
According to the detection result, when the main line is detected to be powered off, the following step S200 is performed.
S200, the intelligent power distribution terminal enters a sleep mode. In the method of the embodiment, a dormant mode is specially set, and when the main line is powered off, namely a stable power source is unavailable, and power distribution can not be normally carried out any more, the intelligent power distribution terminal enters the dormant mode and does not carry out power distribution any more.
Specifically, in the sleep mode, the intelligent power distribution terminal supplies power by using a standby power supply, and the output power of the standby power supply is a second power; when the intelligent power distribution terminal is not in the sleep mode, the intelligent power distribution terminal uses a normal power supply to supply power, and the output power of the normal power supply is first power; the second power is less than the first power. Fig. 2 is a circuit diagram of an example of an intelligent power distribution terminal, in which a normal DC power source is referred to herein as a normal power source. In the method in this embodiment, after the power distribution terminal enters the sleep mode, the high-power output in the normal state is turned off, and the sleep mode with low-power output is started, so that the usage amount of the standby power supply is reduced. The method for calling the standby power supply of the sleep type intelligent power distribution terminal is provided with a special sleep mode, and when a main line is powered off, normal high-power output can be controlled to be turned off, and the standby power supply enters a low-power output state. Therefore, the output of the standby power supply is reduced, the energy consumption is reduced, and the service life of the standby power supply is prolonged while the supply of necessary component power supplies and the basic work of a power distribution terminal are guaranteed.
As shown in fig. 3, after detecting that the main line is powered off, before entering the sleep mode, the method may further include the following steps:
s201, processing power failure items of the intelligent power distribution terminal equipment. After the main line loses power, the current condition of the power distribution terminal needs to be recorded and the like, so that the stability of the power distribution terminal and the downstream is ensured. Specifically, the power-down event in this step includes switching on and off operation, index monitoring, signal acquisition, receipt collection, data processing, and data upload. In the process, after the main line of the intelligent power distribution terminal loses power, the standby power supply is immediately called for processing, in the processing process, the standby power supply is output at first power, most of components connected with the normal power supply are in a working state, even the calling rate is high, and therefore the normal power supply works at the first power at the moment.
In addition, it should be noted that the power-down event includes, in addition to the on/off switch operation, various index detection, and the like, all events that the intelligent power distribution terminal needs to process under the power-down condition of the main line, so as to ensure that the intelligent power distribution terminal can work normally after the main line is powered on, and parameters related to the power-down of all main lines can be reserved.
Furthermore, in the sleep mode, the intelligent terminal closes all invalid functions, including various functions such as monitoring and operation, only keeps the communication function and the minimized operation of the CPU to provide processing functions related to communication information, meanwhile, the sleep signal is transmitted to the normal power supply, after the normal power supply receives the sleep signal, the high-power output in the normal state is closed, the sleep mode with low-power output is started, and the power output only can maintain the operation of the sleep terminal and the communication module.
In this embodiment, except for a Central Processing Unit (CPU), also called a central control module, only the function of the communication module is retained, and this function is that the intelligent power distribution terminal can communicate with the outside, so that the state of the intelligent power distribution terminal can be obtained through a signal, and the intelligent power distribution terminal can also be controlled through the communication module, thereby ensuring the controllability of the intelligent power distribution terminal.
In order to realize the sleep mode of the intelligent power distribution terminal, a sleep power supply module needs to be added into the intelligent power distribution terminal, so that when a main line loses power, the intelligent power distribution terminal sends a sleep signal through the sleep power supply module and controls the intelligent power distribution terminal to enter the sleep mode.
As shown in fig. 4, for the processing in the power-off state of the main line, the intelligent power distribution terminal performs the processing according to the following steps:
and S300, detecting whether the main line is electrified or not, and obtaining a detection result. Two detection results are available, wherein one detection result is that the main line is electrified, the other detection result is that the main line is not electrified, and when the main line is not electrified, the intelligent power distribution terminal continues to keep a sleep mode; when the main line is powered on, the intelligent power distribution terminal enters a normal operation mode from a sleep mode.
It should be noted here that, the detecting whether the main line is powered on may be passive detection, and a stimulus that the power is turned on after the main line is powered on is directly used as a detection signal for powering on.
As shown in fig. 5, the method of an embodiment further includes the following steps:
s400, whether the wake-up signal is received or not is detected, and a detection result is obtained. The detecting step also obtains two detection results, one is that the wake-up signal is detected, and the other is that the wake-up signal is not detected. And if the wake-up signal is not detected, keeping the dormant state of the intelligent power distribution terminal unchanged. But if the wake-up signal is really detected to be received, controlling the intelligent power distribution terminal to enter a normal operation mode from a sleep mode.
It should be noted here that the wake-up signal is a signal requesting to adjust the intelligent power distribution terminal from the sleep mode to the normal operation mode. This signal may contain a variety of external input states, but eventually the summary to the CPU appears as a wake-up signal.
Specifically, the wake-up signal may include a wake-up signal input through the operation mode switching button, or may include a wake-up signal activated according to a preset mode call health condition. As a factual mode, a normal/sleep button can be arranged on the intelligent terminal, the intelligent terminal can be manually switched after automatically entering the sleep mode, and the intelligent terminal can be forcibly and manually waken up/sleeping on site for maintenance personnel to read terminal data on site or debug on site. And a normal/sleep indicator lamp can be arranged on the terminal and displayed according to the actual state. In addition, as can be seen from the foregoing description, during the sleep period, the communication is normally performed, and the intelligent terminal may wake up the entire terminal including the power supply according to the wake-up instruction received by the communication, and may also go to sleep according to the instruction.
As an implementable manner, the intelligent terminal can wake up/sleep the terminal and the power supply at any time according to the conditions set locally in advance.
In addition, as shown in fig. 6, in addition to controlling the intelligent power distribution terminal to enter the sleep mode when detecting that the main line is powered down, the power distribution terminal may also actively enter the sleep mode according to a control signal. Specifically, the method is realized according to the following steps:
s100', the intelligent power distribution terminal detects whether a signal entering a sleep mode is received or not, and a detection result is obtained.
It should be noted that, the intelligent power distribution terminal may execute the step S100' in a normal operation state to detect whether to enter a sleep mode. The detection result also comprises two types, wherein one type is that a signal entering the sleep mode is detected, the other type is that a signal entering the sleep mode is not detected, and if the signal is not detected, the intelligent power distribution terminal continues to normally operate. And if the intelligent power distribution terminal detects that the signal for entering the sleep mode is received, the intelligent power distribution terminal enters the sleep mode. And operates according to various parameters of the sleep mode, and the specific operation process is performed with reference to the foregoing embodiment.
The setting of the step can actively control the intelligent power distribution terminal to enter the dormant mode by setting the mode conversion button at the intelligent power distribution terminal, and has important significance on the processes of equipment maintenance, testing and the like.
In the method implemented in the foregoing, the intelligent power distribution terminal is powered by an energy storage power source in the sleep mode, and the energy storage power source is a super capacitor, a storage battery and/or a flywheel energy storage.
The application simultaneously provides a dormancy type intelligent power distribution terminal, and it includes AC power module, central control module, normality power module and dormancy power module. And the AC power supply module is used for supplying power to the distribution terminal load and charging the super capacitor. The normal power supply module, the switched capacitor circuit module and the dormant power supply module are all electrically connected with the central control module. Specifically, the central control module is configured to execute the method according to any one of the foregoing embodiments to control the operation mode of the power distribution terminal; the normal power supply module is used for supplying power to the devices which still run when the main line is power-off by the power distribution terminal; and the dormant power supply module is used for supplying power to related devices for controlling the dormant mode of the power distribution terminal.

And the super capacitor bank is adopted as an energy storage source at the energy storage end, and the super capacitor bank formed by the super capacitor monomer and the balancing circuit adopts the balancing circuit with ultra-low power consumption, so that the self-loss is reduced.
