Description

Technical Field

[0001] This invention belongs to the field of power distribution technology, and particularly relates to a remote local alarm and three-power-source-uninterrupted switching device. Background Technology

[0002] The reliability of power supply is crucial for the normal operation of various equipment and systems, and its stability directly affects system operation and data security. Therefore, research on power system backup schemes and power switching methods is receiving increasing attention. Existing power management technologies can guarantee power supply to a certain extent, but some significant shortcomings remain.

[0003] Currently, traditional single-power-supply configurations often have certain shortcomings and cannot provide sufficient power assurance. In practical applications, when the main power supply fails: First, due to the lack of a timely alarm system and its corresponding automatic power switching system, the backup power supply cannot start in time, leading to serious consequences such as equipment shutdown and data loss, which poses a significant risk to the stable operation of critical tasks; second, if the mains power outage is prolonged, a typical backup power supply cannot support the normal operation of the system for an extended period; third, if the power switching control device malfunctions, the entire power supply system will be paralyzed, severely affecting the normal operation of the system; and fourth, remote, non-disruptive control is not possible. Summary of the Invention

[0004] The purpose of this invention is to provide a remote local alarm and three-power-supply-free switching device that provides timely alarm during power outages, switches to backup power, switches between automatic and manual dual-insurance power supplies, and provides power for extended periods.

[0005] The objective of this invention is achieved as follows: A remote-to-local alarm and three-power-supply seamless switching device includes a mains power supply, a backup power supply, and a power failure alarm. The mains power supply, backup power supply, and power failure alarm are all electrically connected to a remote control module. The remote control module is also electrically connected to a mains circuit breaker, a backup power circuit breaker, a power output circuit breaker, and a remote-to-local switch. A dual-power seamless switching device is electrically connected to the mains circuit breaker, the backup power circuit breaker, and the power output switch. The remote-to-local switch is used for manual control to indicate whether the remote control module is in use. The remote control module is used to control the mains circuit breaker and the backup power circuit breaker. The power output circuit breaker is used to open and close the power supply. The backup power supply includes a solar power supply and a battery power supply that is charged by the mains power supply. The solar power supply and the battery power supply are electrically connected to the remote control module through a voltage detection module and a power switching module, respectively. When the voltage value measured by the voltage detection module is less than the set voltage threshold, the power switching module switches between the solar power supply and the battery power supply. The dual power supply disturbance-free switch is used to output the power supply without disturbance to the outside through the power output circuit breaker.

[0006] As a further optimization of the above technical solution, the dual-power disturbance-free switch is also electrically connected to the temperature controller, mains power indicator, backup power indicator, and timer, and is used to display the temperature, mains power, backup power, and cumulative time of the current power outage.

[0007] As a further optimization of the above technical solution, the temperature controller is electrically connected to one or more electric fans, and the temperature controller controls the opening and closing of the electric fans.

[0008] As a further optimization of the above technical solution, a power distribution cabinet is provided. The backup power supply, power failure alarm, remote control module, mains air switch, backup power air switch, power output air switch, remote and local switch, and dual power disturbance-free switch are installed on the mounting plate inside the power distribution cabinet. The temperature controller, mains indicator light, backup power indicator light, and timer are installed on the inner door of the power distribution cabinet. An outer door is provided outside the inner door of the power distribution cabinet. The outer door is provided with a transparent cover that allows observation of the working status of the temperature controller, mains indicator light, backup power indicator light, and timer inside the power distribution cabinet.

[0009] As a further optimization of the above technical solution, one or more electric fans are installed on the side wall inside the power distribution cabinet, and the opening and closing of the electric fans are controlled by a temperature controller.

[0010] As a further optimization of the above technical solution, there are two electric fans, which are respectively installed on the side wall inside the power distribution cabinet.

[0011] As a further optimization of the above technical solution, the solar power supply includes a solar photovoltaic array, a charging controller, a battery pack, and an inverter connected in sequence. The battery power supply includes a charging controller, a battery pack, and an inverter connected to the mains power. The power output terminals of the inverter, which is electrically connected to the solar power supply and the battery power supply, are electrically connected to the remote control module through a voltage detection module and a power switching module, respectively.

[0012] As a further optimization of the above technical solution, the remote control module receives the mains power failure signal sent by the power information acquisition terminal and then controls the power failure alarm to sound.

[0013] As a further optimization of the above technical solution, the power failure alarm includes sound alarm, light alarm and power failure signal alarm.

[0014] As a further optimization of the above technical solution, the power failure signal alarm includes: a remote control module is electrically connected to a signal transmitter and a transmitting antenna in sequence, and the remote control module transmits the power failure signal transmitted from the power information acquisition terminal to the outside world through the signal transmitter and the transmitting antenna to remind relevant personnel.

[0015] The advantages of this invention compared to the prior art are: 1. This invention can ensure that remote devices can remotely control the on / off of relevant circuits through a remote control module in the event of a mains power outage, without being affected by the mains power outage, and continue to be powered by a backup power source.

[0016] 2. Power outage alarm: After a power outage, this invention provides the power supply unit with time to understand the power supply status and handle power outage accidents in a timely manner through sound alarm, light alarm and sending power outage signal alarm.

[0017] 3. This invention uses solar power as a backup power source, which saves energy, reduces production costs, and allows for alternating power supply from solar power and battery power during prolonged power outages. When the battery power is supplied, it can charge the solar power source, ensuring the urgent power needs of the user unit after a long power outage.

[0018] 4. In the event of a failure or loss of control of the main line of the remote control module, the present invention can manually switch to the backup power supply for direct external power supply when the "remote-local switch" is moved to the "local" position, and manually switch to the power supply of the remote control module control equipment when the "remote-local switch" is moved to the "remote" position, thus playing a double insurance role and preventing the power distribution cabinet from failing.

[0019] 5. The timer can keep track of the emergency response after a power outage, which helps to understand the rapid response capability after a power outage and provides data and decision-making basis for how to deal with power outages in the future.

[0020] 6. Install an electric fan inside the distribution cabinet. The fan can be turned on in time to cool down the cabinet when the temperature inside exceeds the set value, so as to ensure the safe use of electrical components inside the distribution cabinet.

[0021] 7. This invention employs a dual-power disturbance-free switch, which can seamlessly switch on to the backup power supply in the event of a main power failure or abnormality through high-speed detection and precise control. This ensures continuous operation of the load without voltage interruption or surge. Through high-speed response (switching time can be compressed to 25-40 milliseconds) and precise synchronous control, it effectively avoids motor stalling, sensitive equipment restarts, or production interruptions, thus protecting the equipment safety of end customers.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 : A remote-to-local alarm and three-power-supply-disruption-free switching device includes a mains power supply 10, a backup power supply, and a power failure alarm. The mains power supply, backup power supply, and power failure alarm are all electrically connected to a remote control module. The remote control module is also electrically connected to a mains power circuit breaker, a backup power circuit breaker, a power output circuit breaker, and a remote-to-local switch. A dual-power-disruption-free switch is electrically connected to the mains power circuit breaker, backup power circuit breaker, and power output switch. The remote-to-local switch is used for manual control to indicate whether or not the remote control module is in use. The remote control module is used to control the mains power circuit breaker, backup power circuit breaker, and power output circuit breaker. The backup power supply includes a solar power supply 30 and a battery power supply 20 charged by mains power. The solar power supply 30 and the battery power supply 20 are electrically connected to the remote control module through a voltage detection module and a power switching module, respectively. When the voltage value measured by the voltage detection module is less than the set voltage threshold, the power switching module switches between the solar power supply 30 and the battery power supply 20 for external power supply. The dual-power disturbance-free switch is used to output the power from the mains power switch or the backup power switch switched by the remote control module without disturbance to the outside through the power output switch.

[0024] As a further optimization of the above technical solution, the dual-power disturbance-free switch is also electrically connected to the temperature controller, mains power indicator, backup power indicator, and timer, and is used to display the temperature, mains power, backup power, and cumulative time of the current power outage.

[0025] As a further optimization of the above technical solution, the temperature controller is electrically connected to one or more electric fans, and the temperature controller controls the opening and closing of the electric fans.

[0026] As a further optimization of the above technical solution, a power distribution cabinet is provided. The backup power supply, power failure alarm, remote control module, mains air switch, backup power air switch, power output air switch, remote and local switch, and dual power disturbance-free switch are installed on the mounting plate inside the power distribution cabinet. The temperature controller, mains indicator light, backup power indicator light, and timer are installed on the inner door of the power distribution cabinet. An outer door is provided outside the inner door of the power distribution cabinet. The outer door is provided with a transparent cover that allows observation of the working status of the temperature controller, mains indicator light, backup power indicator light, and timer inside the power distribution cabinet.

[0027] As a further optimization of the above technical solution, one or more electric fans are installed on the side wall inside the power distribution cabinet, and the opening and closing of the electric fans are controlled by a temperature controller.

[0028] As a further optimization of the above technical solution, there are two electric fans, which are respectively installed on the side wall inside the power distribution cabinet.

[0029] As a further optimization of the above technical solution, the solar power supply includes a solar photovoltaic array, a charging controller, a battery pack, and an inverter connected in sequence. The battery power supply includes a charging controller, a battery pack, and an inverter connected to the mains power. The power output terminals of the inverter, which is electrically connected to the solar power supply and the battery power supply, are electrically connected to the remote control module through a voltage detection module and a power switching module, respectively.

[0030] As a further optimization of the above technical solution, the remote control module receives the mains power failure signal sent by the power information acquisition terminal and then controls the power failure alarm to sound.

[0031] As a further optimization of the above technical solution, the power failure alarm includes sound alarm, light alarm and power failure signal alarm.

[0032] As a further optimization of the above technical solution, the power failure signal alarm includes: a remote control module is electrically connected to a signal transmitter and a transmitting antenna in sequence, and the remote control module transmits the power failure signal transmitted from the power information acquisition terminal to the outside world through the signal transmitter and the transmitting antenna to remind relevant personnel.

[0033] The working process of this invention: This invention uses both solar power and battery power as dual backup power sources. Normally, the battery power source uses mains power to charge the battery pack via a charging controller. An inverter converts the 24V voltage to 220V for emergency backup power in case of mains power failure. The solar power source uses a solar photovoltaic array to receive solar energy, which is converted into electrical energy by the charging controller to charge the battery pack. An inverter then converts the 24V voltage to 220V for emergency backup power in case of mains power failure. The power supply sequence for the dual backup power sources is: the power switching module prioritizes the solar power source as backup, followed by the battery power source. The solar power source serves as an auxiliary backup power source. In the event of a mains power outage, the solar power source is the primary backup power source. Once the voltage detection module detects that the voltage value of the solar power source is lower than the set threshold, the power switching module automatically shuts off the solar power source and simultaneously turns on the battery power source to supply power to the outside. While the battery power source is supplying power to the outside, the solar photovoltaic array can charge the energy storage battery pack. Once the voltage detection module detects that the voltage value of the battery power source is lower than the set threshold, the power switching module automatically shuts off the battery power source and simultaneously turns on the solar power source, allowing the solar power source to supply power to the outside again, further extending the backup power supply time.

[0034] After the power switching module receives the voltage value of the battery power detected by the voltage detection module as being less than the set threshold (e.g., 180V), it can switch the power supply between the solar power and the battery power through control circuits such as programmable controller, thyristor module, IGBT module, IGCT module, IPM module, and relay. For example, the principle and circuit of the "Fast Dual Power Switch" disclosed in Chinese Patent Publication No. CN200994080Y can be used to switch the power supply between the solar power and the battery power.

[0035] When the mains power fails, the remote control module receives the mains power failure signal from the power information acquisition terminal and controls the power failure alarm to issue an audible alarm, a light alarm, and send a power failure signal alarm as a warning.

[0036] After the remote local switch is manually moved to local mode, the backup power supply directly outputs backup power, and the remote control module fails.

[0037] When the remote local switch is manually moved to remote mode, the remote control module controls the backup power supply to provide external power: 1) When normally powered by mains electricity: the mains power supply passes through the remote control module, mains circuit breaker, dual power supply disturbance-free switch, and power output circuit breaker to supply power to the outside.

[0038] 2) During the mains power supply process, when the remote control module receives the power failure signal, it controls the mains power circuit breaker to close, the backup power circuit breaker to open, and the power output circuit breaker to open. The backup power supply then passes through the voltage detection module, the power switching module, the remote control module, the backup power circuit breaker, the dual power disturbance-free switch, and the power output circuit breaker to supply power to the outside in sequence.

[0039] 5. Power management personnel can not only receive audible alarms, light alarms, and power outage alarm information from the power failure alarm at any time, but also observe the working status of the temperature controller, mains power indicator, backup power indicator, and timer inside the power distribution cabinet through the transparent cover on the outer door of the power distribution cabinet, so as to take the next step in a timely manner.

[0040] 6. When the temperature inside the power distribution cabinet exceeds a set value (e.g., 40 degrees Celsius), the temperature controller can promptly activate the fan to cool the cabinet, thereby ensuring the safe use of electrical components within the power distribution cabinet.

[0041] 7. After receiving the signal from the power information acquisition terminal that the mains power has been restored, the remote control module immediately turns on the mains power circuit breaker, turns off the backup power circuit breaker, and controls the mains power to supply power to the outside in sequence through the remote control module, the mains power circuit breaker, the dual power disturbance-free switch, and the power output circuit breaker.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that simple substitutions or modifications can still be made to the technical solutions or technical features described in the foregoing embodiments, and these simple substitutions or modifications do not cause the essence of the corresponding technical solutions to deviate from the spirit and substance of the technical solutions of the embodiments of the present invention, and are still within the protection scope of the present invention.
