Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
At present, in order to prevent power failure in life, a user can set an emergency power supply, and a circuit schematic diagram is shown as 1. Under normal conditions, the storage battery is charged by power supply lines (L and N); when power is cut off, the storage battery automatically supplies power to the lamp, and the lamp is lighted at the moment, so that the effect of an emergency lamp is achieved. In addition, a switch K is provided on the power supply line, and a user can switch the emergency lamp L0 to the power supply line via the switch K. However, if the emergency lamp is turned on when a power failure event occurs in life, if the power failure event occurs in daytime or at home and the user needs to go out, in order to avoid electric energy waste, the user can only wait for the power supply line to come in or take off the lamp to turn off the emergency lamp, or the emergency lamp is cut off through the switch K, but the user needs to actively switch back the emergency lamp after the user happens, and once the user forgets to switch back the emergency lamp, the emergency lamp cannot be used for emergency.
In order to solve the above problem, an embodiment of the present invention provides an intelligent emergency power supply, and fig. 2 is a schematic circuit diagram of the intelligent emergency power supply according to the embodiment of the present invention. Referring to fig. 2, an intelligent emergency power supply includes: a switch module 201, a control module 202 and an energy storage module 203. Wherein the content of the first and second substances,
the switch module 201 is connected in series to a first power line L of a power supply (represented by power lines L and N; when the power supply is an ac power supply, the power line L can be understood as a live line, and the power line N can be understood as a zero line; when the power supply is a dc power supply, the power line L can be understood as a positive line, and the power line N can be understood as a negative line); the energy storage module 203 is connected with the switch module 201;
the control module 202 is connected to the switch module 201 and the energy storage module 203, respectively, and is configured to obtain a switch state of the switch module 201 and determine whether to supply power to the electrical load 204 according to the switch state.
In the embodiment, the energy storage module 203 provides a detection voltage or current through a connection line with the switch module 201, and when the switch state of the switch module 201 changes, different loops can be formed. In this way, the control module 202 can determine the loop between the switch module 201 and the energy storage module 203 by detecting the voltage or current of each connection line, and then determine the switch state of the switch module 201, i.e. whether the detection time is an open state or a closed state.
IN one embodiment, referring to fig. 3 and 4, the switch module 201 may include a single-pole double-throw switch K1, a first input terminal IN1, a second input terminal IN2, and an output terminal OUT. The first terminal, the second terminal and the output terminal (not shown) of the single-pole double-throw switch K1 are respectively connected to the first input terminal IN1, the second input terminal IN2 and the output terminal OUT of the switch module 201. The first input terminal IN1 of the switch module 201 is connected to a section of the first power line L near the power supply (not shown), and the output terminal OUT of the switch module 201 is connected to a section of the first power line L near the power load 204. The output OUT and the second input IN2 of the switch module 201 are respectively connected to the positive output (denoted by the "+" symbol IN the figure) and the negative output (denoted by the "-" symbol IN the figure) of the energy storage module 203. The switch module 201 is configured to switch the switch states according to the user's trigger operation, where the switch states include a closed state corresponding to the connection of the first input terminal IN1 and the output terminal OUT and an open state corresponding to the connection of the second input terminal IN2 and the output terminal OUT. The working process of the switch module 201 includes:
first, operating state 1. The user can trigger the single-pole double-throw switch K1 to be closed, i.e. the first input terminal IN1 and the output terminal OUT of the switch module are connected.
In this operating state, the power supply includes a power-on or power-off condition. IN one embodiment, the control module 202 is connected to the first input IN1 of the single-pole double-throw switch K1, so that the power on or off of the power supply can be determined by the control module 202 itself. For example, when the power supply is powered and the first power line L is at a high voltage level, the control module 202 may detect that the first input terminal IN1 is at a high voltage level. For another example, when the power supply fails, the first power line L is low, and the control module 202 can detect that the first input terminal IN1 is low. That is, the control module 202 determines whether the power supply is powered off or not by the potential at the first input terminal IN 1.
(1) Power supply power on condition
If the power consumption load 204 is a power consumption load that needs to operate for a long time, such as a router, a refrigerator, or a socket, the single-pole double-throw switch K1 is closed. With continued reference to fig. 3, the current flow paths are: the power supply, the first input terminal IN1, the output terminal OUT, the connection node a, the connection node b, the consumer load 204, and the second power line N are finally injected into the power supply. Therefore, the electric load can be supplied by the power supply, and the purpose of long-term work is achieved.
Meanwhile, the energy storage module 203 is connected with a second input end IN2 of the single-pole double-throw switch K1, the control module 202 and the positive output end of the energy storage module 203. Since the second input terminal IN2 and the output terminal OUT are not connected, the control module 202 cannot detect current at the positive output terminal of the energy storage module 203, that is, the detection loop (the positive output terminal of the energy storage module, the connection node c, the second input terminal IN2, the output terminal OUT, the connection node a, the connection node b, and the negative output terminal of the energy storage module) does not exist, and the current at the positive output terminal is smaller than the current threshold (which may be set to several microamperes or several milliamperes, which may be understood as a leakage current IN the circuit). In this way, the control module 202 can determine that the spdt switch K1 is in the closed state and the control switch C remains in the open state without the energy storage module 203 supplying power to the electrical load 204.
If the electric load 204 is an electric load such as an emergency lamp that needs emergency operation, a connection line between the electric load 204 and the second power line N may be eliminated. When the single-pole double-throw switch K1 is in a closed state, the power load does not need to be supplied with power, and a circuit diagram is shown in figure 4.
(2) Power failure condition of power supply
In this case, the electric load needs the intelligent emergency power supply for supplying power. With continued reference to fig. 3 and fig. 4, the control module 202 controls the switch C to be closed, and at this time, a power supply loop is formed between the energy storage module 203 and the electrical load, and the current flows through the following paths: the positive output end of the energy storage module 203, the connection node C, the switch C, the electric load 204, the connection node b and the negative output end of the energy storage module 203.
Second, operating state 2. The user can trigger the single-pole double-throw switch K1 to be IN the on state, i.e. the second input terminal IN2 and the output terminal OUT of the switch module 201 are connected.
Since the spdt switch K1 is in the on state, which may be the result of a user-triggered operation, for example, a user-triggered operation after a power failure, or a user-triggered operation due to maintenance, the control module 202 cannot determine whether the power supply has a power failure. To ensure the safety of power utilization, the control module 202 may obtain the historical operating status of the intelligent emergency power supply. Wherein the historical operating state may include: emergency power supply state and standby state. For example, when the historical operating state of the intelligent emergency power supply is the emergency power supply state, the control module 202 controls the energy storage module 203 (or the dc power supply module) to stop supplying power to the power load. For another example, when the historical operating state of the intelligent emergency power supply is the standby state, the control module 202 controls the energy storage module 203 (or the dc power module) to maintain the state of not supplying power to the power load.
In another embodiment, referring to fig. 5, the switch module 201 may further include a diode D and a resistor R. A cathode of the diode D (left end of the diode IN fig. 5) is connected to the second end of the single-pole double-throw switch K1 (the end corresponding to the second input end IN2 of the switch module 201), and a resistor R is connected IN series between an anode of the diode D (right end of the diode IN fig. 5) and the output end of the single-pole double-throw switch K1 (the end corresponding to the output end OUT of the switch module 201). In this embodiment, the diode D is disposed to prevent the current of the power supply from affecting the energy storage module 203 when the current comes from the right side of the first power line L (e.g. the end of the first power line far from the label L in fig. 5). In this embodiment, the condition that the energy storage module 203 is short-circuited when the single-pole double-throw switch K1 is in an on state can be avoided by setting the resistor R, so as to achieve the purpose of protecting the energy storage module 203.
In an embodiment, the control module 202 may be implemented by hardware such as a single chip, an ARM chip, and an FPGA, or may be implemented by software having the same function, and a technician may select the hardware according to a specific scenario, which is not limited herein.
In an embodiment, the energy storage module 203 may be implemented by a battery including a lithium battery, a fuel cell, and the like, and a corresponding driving circuit. In practical applications, the energy storage module 203 may select an appropriate type according to the electrical load: for example, if the electrical load is an LED lamp, the energy storage module 203 may include a storage battery; for another example, if the power load is a refrigerator, the energy storage module 203 may include a power battery, etc.; if the power consumption load is power consumption of a certain industrial plant area, the energy storage module 203 may be a standby generator. The skilled person may choose according to a specific scenario, which is not limited herein.
In an embodiment, when the load of the electric load is small, the energy storage module 203 may also supply power to the electric load, and the energy storage module 203 is connected to the control module 202. When the power supply to the electric load 204 is determined, the control module 202 controls the energy storage module 203 to be turned on, so that the energy storage module 203 and the electric load 204 can form a power supply loop, and the energy storage module 203 supplies power to the electric load 204. When it is determined that power supply to the electric load 204 is not needed, the control module 202 controls the energy storage module 203 to be turned off, so that a power supply loop between the energy storage module 203 and the electric load 204 is disconnected, and the energy storage module 203 cannot supply power to the electric load 204.
It can be understood that, to ensure that the energy storage module 203 has sufficient electric energy, the energy storage module 203 may be connected to a power supply (not shown in the figure), and when the control module 202 determines that it is not necessary to supply power to the electric load, the energy storage module 203 and the power supply are controlled to form a charging loop, so that the power supply can charge the energy storage module 203 until the charging is completed or the charging loop is closed when it is necessary to supply power to the electric load 204.
In another embodiment, when the load of the electric load is large, the energy storage module 203 cannot supply power to the electric load, and the intelligent emergency power source may include a dc power module (not shown) connected to the control module 202. When the power supply to the electric load 204 is determined, the control module 202 controls the dc power module to be turned on, so that the dc power module and the electric load 204 may form a power supply loop, and the dc power module supplies power to the electric load 204. When it is determined that power is not required to be supplied to the electrical load 204, the control module 202 controls the dc power module to be turned off, so that the power supply loop between the dc power module and the electrical load 204 is disconnected, and the dc power module cannot supply power to the electrical load 204.
It can be understood that, in order to ensure that the dc power module has sufficient electric energy, the dc power module may be connected to a power supply, and when the control module 202 determines that it is not necessary to supply power to the electric load, the dc power module and the power supply are controlled to form a charging loop, so that the power supply may charge the dc power module until the charging is completed or the charging loop is closed when it is necessary to supply power to the electric load 204.
In this embodiment, the energy storage module 203 is connected to the switch module 201 connected in series to the first power line L of the power supply, so that the control module 202 can obtain the on-off state of the switch module 201 according to the condition that the energy storage module 203 and the switch module 201 form a loop, and determine whether to supply power to the power load 204 according to the on-off state. It can be seen that, in this embodiment, power supply or power failure to the electric load 204 is determined according to the on-off state of the switch module 201, so that the problem that the electric load 204 does not need to supply power under the power failure condition can be solved, the purpose of saving electric energy is achieved, and further the use experience of a user can be improved.
It should be noted that, for the convenience of the skilled person to understand the solution of the present application, the energy storage module 203 is described as an example to supply power to the electrical load.
Fig. 6 is a schematic view of a scene of an emergency lamp including the intelligent emergency power supply shown in fig. 2 to 5 according to an embodiment of the present invention. Referring to fig. 6, the intelligent emergency power supply and the LED module constitute an intelligent emergency lamp. Wherein, the LED module is an LED lamp L1. The intelligent emergency power supply comprises a storage battery B, a single-pole double-throw switch K1, a diode D, a resistor R and a control module 202. The positive output end of the storage battery B is connected with the anode of the diode D through the resistor R, and the cathode of the diode is connected with the second input end IN2 of the single-pole double-throw switch K1. The single-pole double-throw switch K1 is connected IN series to a first power line L of a power supply, and a first input end IN1 and an output end OUT of the single-pole double-throw switch K1 are respectively connected with the first power line L. The output terminal OUT of the single-pole double-throw switch K1 is also connected with the negative output terminal of the battery B through a connecting line ab. The positive output of the battery is connected to the LED lamp L1 through switch C and then to the negative output of the battery. The control module 202 is connected to a positive output terminal (not shown) of the battery B, a first input terminal IN1 of the single-pole double-throw switch K1, and a switch C, respectively. The operation of the emergency light of fig. 6, see fig. 7, includes:
when the first input terminal IN1 of the spdt switch K1 is connected to the output terminal OUT, the control module 202 detects that the real-time current at the positive output terminal of the battery B is 0, and at this time, the control module 202 determines that the spdt switch K1 is IN a closed state. Then, the control module 202 detects the potential of the first input terminal IN1 of the single pole double throw switch K1. If the detection result shows that the first input end IN1 is at a high potential, the control module 202 determines that the power supply is powered on, and at the moment, determines that the intelligent emergency power supply is IN a standby state, does not need to supply power to the LED lamp L1, and keeps the LED lamp L1 IN an off state. When the battery B is not powered, the control module 202 or the control chip of the battery B may be charged according to the condition of the electric quantity of the battery B. If the detection result indicates that the first input end IN1 is at a low potential, the control module 202 determines that the power supply has a power failure, and at this time, the intelligent emergency power supply needs to be supplied to the LED lamp L1 and adjusted to an emergency power supply state, so that the LED lamp L1 is turned on.
When the second input end IN2 of the single-pole double-throw switch K1 is connected to the output end OUT, the control module 202 detects the real-time current at the positive output end of the battery B, and if the real-time current is greater than or equal to the current threshold, the control module 202 determines that the single-pole double-throw switch K1 is IN an on state. Control module 202 then obtains the last historical operating state of the intelligent emergency power supply.
