The outage probability and clutter crosstalk are larger. The basic connection mode is as follows: mains supply, uninterruptible power supply and equipment use. When the uninterrupted power supply fails, bypass power supply cannot be carried out or the storage battery pack fails, all relevant equipment is powered off.
Along with the progress of scientific technology, the requirements on the communication data of basic network points and the power supply reliability of security monitoring equipment are higher and higher, so how to ensure the power supply reliability becomes a key problem needing attention. In the past, two paths of power supplies often need manual operation to achieve the purpose of switching the power supplies, so that accidents are often caused by misoperation. Therefore, the application provides a control method, a system, a device, equipment and a storage medium for load power supply, and the purpose of realizing power supply switching is achieved by controlling a switching device.
Fig. 1 shows a flowchart of a control method for power supply of a load according to an embodiment of the present application.
In some embodiments, as shown in fig. 1, a control method for power supply of a load includes:
s10: a power supply state of a first power supply system that supplies power to a load device is detected.
Under normal conditions, the load equipment is base station communication data and security monitoring equipment, and only one power supply system is needed for supplying power to the base station communication data and the security monitoring equipment, so that when the power supply system of the load equipment is a first power supply system, the power supply state of the first power supply system can be detected, and the detection of the power supply state can be conceivable to detect whether output voltage or output current exists in the power supply system or not, so that a voltmeter or ammeter can be installed at the output end of the power supply system to detect the power supply state of the power supply system in real time.
S11: and when the power supply state is a fault, controlling a switching device connected with the first power supply system and the second power supply system, switching from the first power supply system to the second power supply system, and supplying power to the load equipment by the second power supply system.
When the power supply state of the first power supply system is detected to be faulty, the power supply system for supplying power to the load device can be switched from the first power supply system to the second power supply system by controlling the switching device connected with the first power supply system and the second power supply system, so that the two power supply systems can be selected to be connected with the switching device at the same time, and then the switching device is connected with the load device. The power supply system for switching the load equipment is controlled by the control switching device, when one power supply system fails, the other power supply system can be switched in time to supply power for the load equipment, so that continuous work of the load equipment is realized, normal use of communication data and security monitoring equipment of a base network point is ensured, and safety of the communication data is improved.
In some embodiments, the first power supply system is an uninterruptible power supply system and the second power supply system is a utility power supply system; or the first power supply system is a commercial power supply system, and the second power supply system is an uninterruptible power supply system.
The load device can be powered by two power supply systems under normal conditions, one is an uninterruptible power supply system and the other is a commercial power supply system, so that the uninterruptible power supply system can be selected as a first power supply system and the commercial power supply system is a second power supply system; the utility power supply system can be selected as the first power supply system, the uninterruptible power supply system is selected as the second power supply system, one of the uninterruptible power supply system and the second power supply system is selected as the first power supply system to supply power for the load equipment under normal conditions, and the other power supply system is switched to be used as the second power supply system to supply power for the load equipment when the first power supply system fails, so that continuous power supply for the load equipment is realized.
In some embodiments, the power supply state comprises an output voltage of the first power supply system, and after detecting the power supply state of the first power supply system that powers the load device, the method further comprises:
s101: it is determined whether the output voltage satisfies less than a preset voltage.
After detecting that the output voltage exists in the first power supply system, the output voltage of the first power supply system can be measured by installing a voltmeter at the output end of the first power supply system, and then judging whether the output voltage is smaller than a preset voltage or not.
S102: and under the condition that the output voltage is smaller than the preset voltage, determining that the power supply state is a fault.
When the output voltage of the first power supply system is determined to be smaller than the preset voltage, the voltage provided by the power supply system can be considered to be incapable of enabling the load equipment to work normally, and therefore the power supply state is considered to be a fault. At this time, the power supply system needs to be switched for the load device. The power supply state of the first power supply system is judged by comparing the output voltage of the first power supply system with the preset voltage, so that whether the first power supply system can provide rated voltage for normal operation for load equipment or not can be intuitively and clearly displayed.
In some embodiments, before controlling the switching device connected to the first power supply system and the second power supply system to switch from the first power supply system to the second power supply system, the method further comprises, prior to powering the load device by the second power supply system:
s103: and detecting the voltage of the second power supply system when the power supply state is a fault.
When the first power supply system is determined to be in fault and the power supply system needs to be switched to the second power supply system, the voltage of the second power supply system needs to be detected, so that a voltmeter can be installed at the output end of the second power supply system to detect the voltage of the second power supply system. After the voltage of the second power supply system is detected, the voltage of the second power supply system can be compared with a preset voltage to judge whether the voltage of the second power supply system is larger than the preset voltage or not so as to judge whether the second power supply system can enable the load equipment to work normally or not.
S104: and under the condition that the voltage of the second power supply system is larger than or equal to the preset voltage, controlling a switching device connected with the first power supply system and the second power supply system to switch from the first power supply system to the second power supply system, and supplying power to the load equipment by the second power supply system.
When it is determined that the voltage of the second power supply system is greater than or equal to the preset voltage, that is, when the load device can normally operate under the voltage provided by the second power supply system, the switching device can be controlled to switch the power supply of the load device from the first power supply system to the power supply of the second power supply system.
It is conceivable that the switching means will not be controlled to switch the power supply system in the embodiment of the application if the voltage of the second power supply system is smaller than the preset voltage, that is to say the second power supply system is not able to normally supply the load device. By measuring the voltage of the second power supply system to be switched before the power supply system is switched for the load equipment and comparing the voltage with the preset voltage, whether the second power supply system can provide the rated voltage required by normal operation for the load equipment or not can be determined, and the switching efficiency of switching the load equipment to the normal power supply system can be improved only when the second power supply equipment supplies power normally.
In some embodiments, the switching means comprises a static switch; when the power supply state is a failure, controlling a switching device connected to the first power supply system and the second power supply system to switch from the first power supply system to the second power supply system, and supplying power to the load device by the second power supply system, the switching device comprising:
and under the condition that the power supply state is a fault, controlling a static change-over switch connected with the first power supply system and the second power supply system, switching from the first power supply system to the second power supply system, and supplying power to the load equipment by the second power supply system.
The switching device can be a static change-over switch which is mainly used for switching the power supply of two paths of power supplies and is an automatic switching system for the power supply of which the power supply is one of two paths. In a normal working state, the main power supply is in a normal voltage range, and the load is always connected with the main power supply. When the main power supply fails, the load is automatically switched to the standby power supply, and after the main power supply is recovered to be normal, the load is automatically switched to the main power supply.
The static change-over switch is one of common important equipment in a data center power supply and distribution system, bears a basic function for guaranteeing the electricity reliability of a terminal core load, and has close connection with the whole power supply and distribution system architecture design. Similar to an automatic change-over switch, the basic structure of the static change-over switch is that two incoming lines are provided with one outgoing line, wherein the two incoming lines are standby, and only one power supply is loaded at the same time.
The static change-over switch is mainly composed of intelligent control board, high-speed controllable silicon and circuit breaker, and is a contactless electronic switch, namely two bidirectional diodes, and is an AC switch composed of controllable silicon elements, and the on and off of the AC switch is controlled by logic controller. The switching of the power supply system is realized through the static change-over switch, so that the labor cost can be reduced, and the safety of switching operation is improved.
In some embodiments, the method further comprises:
s12: when the power supply state is a failure, failure information is generated.
When it is determined that the power supply state of the first power supply system fails, failure information is generated, where the failure information may be an alarm prompt set by people, for example, an alarm sound or an alarm flashing light, and it is conceivable that the failure information further includes text prompt information and the like, which is not described herein.
S13: and sending fault information to the terminal equipment, wherein the fault information is used for prompting a user of the first power supply system to be faulty by the terminal equipment.
After the fault information is generated, the fault information can be sent to the terminal equipment, and the user of the terminal equipment can acquire that the first system breaks down at the first time by sending the fault information to the terminal equipment, so that subsequent maintenance and other operations on the first system are facilitated.
