Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following embodiments and accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Referring to fig. 1, a structure diagram of a power supply module disclosed in the embodiments of the present application is shown, where the power supply module may include a power monitoring unit 10, a power switching unit 20, an ac power supply 30, a built-in storage battery 40, and a dc power supply 50, and the power supply module may be applied to any electrical appliance, and is suitable for a scenario with a high requirement on power supply stability, such as a power plant, a large-scale thermoelectric unit, and the like.
In particular, the amount of the solvent to be used,
when power supply is started, the power supply switching unit 10 can control the alternating current power supply 30 to supply power to the electrical appliance;
when the power monitoring unit 10 monitors that the ac power supply 30 does not satisfy the preset ac power supply condition and the internal storage battery 40 satisfies the preset storage battery power supply condition, the power switching unit 20 may be triggered to switch to the internal storage battery 40 for power supply;
when the power monitoring unit 10 monitors that the internal storage battery 40 does not satisfy the storage battery power supply condition and the ac power supply 30 still does not satisfy the ac power supply condition, the power switching unit 20 may be triggered to switch to the dc power supply 50 for supplying power.
Further, the power switching unit 20 may control which power source supplies power by using the contactor, and the power monitoring unit 10 may determine whether the power source needs to be replaced by monitoring power supply parameters such as voltage and current. The contactor can be divided into an alternating current contactor (voltage AC) and a direct current contactor (voltage DC), and can be applied to electric power, distribution and power utilization occasions. The contactor is an electric appliance which utilizes a coil to flow current to generate a magnetic field in industrial electricity to close a contact so as to control a load. In this specification, a contactor may be used to control a power supply that provides power.
The power monitoring unit 10 may be connected to each power source for monitoring output parameters of each power source, such as voltage, current, power, etc.
In one embodiment, to implement power supply monitoring, the power supply monitoring unit 10 may be installed inside the power supply module or in the electrical appliance.
Fig. 1 is a schematic structural diagram of a power supply module in which a power monitoring unit 10 is installed inside the power supply module. When the power supply monitoring device is installed in a power supply module, the output power supply of the power supply module can be monitored during power supply monitoring, for example, the output power supply can be instantaneous voltage, instantaneous current, or the average value of voltage and current in a period of time, and the like.
Fig. 2 is a schematic structural diagram of a power supply module in which the power monitoring unit 10 is installed in an electrical appliance. When the device is installed in an electrical appliance, the input power supply of the electrical appliance can be monitored, specifically, the device can also be instantaneous voltage, instantaneous current, or the average value of the voltage and the current within a period of time, and the like.
In an embodiment, the power monitoring unit 10 may be split into two units, which are respectively installed inside the power supply module and in the electrical appliance, so as to monitor both the condition of the power supply module and the condition of the electrical appliance.
In one embodiment, since different power sources have different characteristics, a corresponding power supply condition may be preset for each power source. For example, for an ac power supply, ac power supply conditions may be preset, and similarly, for a battery, also battery power supply conditions may be preset, and for a dc power supply, also dc power supply conditions may be preset.
Specifically, as for the ac power supply condition, as described above, a higher requirement may be imposed on the instantaneous voltage, for example, a relationship with an ac voltage preset value may be used as a basis for determining whether the ac power supply condition is satisfied, and the ac voltage preset value may be regarded as a value proposed according to the power supply requirement. If the instantaneous alternating voltage is not lower than the preset value of the alternating voltage, the alternating current power supply condition is met, otherwise, the alternating current power supply condition is not met.
The relationship between the average value of the voltages within a period of time and the stable value of the alternating voltage can be used as a basis for judging whether the alternating current power supply condition is met, and the stable value of the alternating voltage can also be regarded as a value provided according to the power supply requirement. For example, for an ac power supply, if the voltage average value is not lower than the ac voltage stable value within a predetermined first time period (which may be preset to 10 seconds), the ac power supply condition is considered to be satisfied, otherwise, the ac power supply condition is not satisfied. Specifically, for example, the voltage preset value may be 219.5V (volt), and the voltage stable value may be 219.6V. I.e., the power supply requirements set forth for a 220V voltage output, allow for small fluctuations in voltage. Similarly, a current preset value, a predicted current stabilization value, and the like may also be set for the current.
And for the storage battery power supply condition, the relation between the storage battery power supply condition and a preset storage battery voltage preset value can be used as a basis for judging whether the storage battery power supply condition is met, if the instantaneous storage battery voltage is not lower than the storage battery voltage preset value, the storage battery power supply condition is met, and otherwise, the storage battery power supply condition is not met.
Similarly, the relationship between the average value of the voltages in a period of time and the preset stable value of the battery voltage can also be used as a basis for judging whether the battery power supply condition is satisfied, for example, for the battery, if the average value of the voltages in the predetermined second period of time (which can be preset to be 5 seconds) is not lower than the stable value of the battery voltage, the battery power supply condition is considered to be satisfied, otherwise, the battery power supply condition is not satisfied.
For the particularity of the storage battery, an electric quantity threshold may also be set as a storage battery power supply condition, for example, 10%, when the remaining electric quantity is not lower than the electric quantity threshold, the storage battery power supply condition may be considered to be satisfied, otherwise, the storage battery power supply condition is not satisfied.
Due to the particularity of the storage battery that it needs to be repeatedly charged and discharged, if it is ensured that power can be supplied at any time, it is necessary to maintain a power supply state. Therefore, in an embodiment, when the power monitoring unit 10 detects that the internal battery 40 does not satisfy the battery power supply condition, the power switching unit 20 may be triggered to control the ac power supply 30 or the dc power supply 50 to charge the internal battery 40.
Specifically, when the power monitoring unit 10 monitors that the internal storage battery 40 does not satisfy the storage battery power supply condition, power supply switching may be performed, for example, power supply may be switched to the ac power supply 30, and power supply may also be switched to the dc power supply 50. Then, there is an idle power supply, and the battery can be charged by the idle power supply under control so as to be used again later.
In practical application, most electrical apparatus all adopt alternating current power supply, so the utility model provides a power supply module also can use alternating current power supply to give first place to. Therefore, in an embodiment, when the power monitoring unit 10 monitors that the ac power supply 30 in the non-power supply state recovers to meet the ac power supply condition, the power switching module 20 may be triggered to switch to the ac power supply 30 for supplying power.
Specifically, the ac power supply condition may be as described above, where the instantaneous ac voltage is not lower than the preset value of the ac voltage, and the voltage average value in the predetermined first time period is not lower than the stable value of the ac voltage, and of course, various preset values for the current may be included. The power supply monitoring unit 10 may monitor the power supply parameter of the ac power supply when switching to the internal battery 40 or the dc power supply 50 for power supply, and may continue power supply from the ac power supply 30 when the power supply returns to a state in which power supply is possible.
In practical applications, if one power supply is supplied for too long, the failure rate may also be increased, so in an embodiment, in order to prevent a certain power supply load from being excessive during the power supply process, when the power monitoring unit 10 monitors that the power supply duration of any one of the ac power supply 30, the internal storage battery 40, and the dc power supply 50 exceeds a preset maintenance duration, the power switching module 20 may be triggered to switch one of the other two power supplies.
Specifically, for a single power supply, the longer the power supply time is, the higher the probability of failure is, so a maintenance duration may be preset, for example, in units of hours or days, and if the power supply continues to supply power for more than the maintenance duration, the power supply switching module may be triggered to switch one of the other two power supplies. For example, if the ac power supply continues to supply power for more than 24 hours, the power supply may be switched to the internal battery or the dc power supply.
It has been mentioned above that a dc supply condition can also be preset for the dc power supply, for example, a dc supply condition can also be similar to the ac supply condition, and reasonable supply requirements can be made for the voltage and the current.
Therefore, in an embodiment, when the power monitoring unit 10 monitors that the internal storage battery 40 does not satisfy the storage battery power supply condition and the ac power supply 30 still does not satisfy the ac power supply condition, the power switching unit 20 may be triggered to switch the dc power supply 50 to supply power, and the method may include:
when the power monitoring unit 10 monitors that the internal storage battery 40 does not satisfy the storage battery power supply condition, the ac power supply 30 still does not satisfy the ac power supply condition, and the dc power supply 50 satisfies the preset dc power supply condition, the power switching unit 20 may be triggered to switch the dc power supply 50 to supply power.
Specifically, if the built-in storage battery is unable to supply power, it is possible to monitor whether the ac power supply and the dc power supply respectively satisfy respective ac power supply conditions and dc power supply conditions. If the AC power supply does not meet the AC power supply condition and the DC power supply meets the DC power supply condition, the DC power supply can be switched to supply power. In practical applications, of course, if both satisfy respective power supply conditions, either one of them may be selected, or an ac power supply is preferred.
In practical applications, the dc power may be converted into ac power for supplying power in accordance with a necessary power supply demand.
In practical application, a fault that needs to be repaired manually may occur in a certain power supply, and the occurrence of the fault generally causes that the power supply cannot meet corresponding power supply conditions for a long time. Therefore, in an embodiment, in order to find the power supply module has a fault in time and repair the fault in time, when the power monitoring unit 20 monitors any one of the ac power supply 30, the internal storage battery 40, and the dc power supply 50 and continues not to satisfy the corresponding power supply condition for more than a preset alarm duration, an alarm notification is sent.
Specifically, the alarm duration may be preset to be 1 hour, that is, if the power monitoring unit 10 monitors that a certain power supply exceeds 1 hour and cannot continuously meet the corresponding preset power supply condition, it indicates that a fault that needs to be manually repaired occurs in the power supply, and at this time, an alarm notification, such as a mail or a short message, may be sent to a specified location, so that the engineer can repair the power supply as soon as possible.
It can be seen from the technical scheme that the embodiment provided above provides, the utility model provides a power supply module can be when starting the power supply, by the power switching unit, control alternating current power supply supplies power, utilize power monitoring unit to monitor the power supply condition afterwards, unsatisfied power supply condition when alternating current power supply, and when built-in battery satisfied power supply condition, then can switch to the battery power supply, can continue the monitoring afterwards, also unsatisfied power supply condition when monitoring built-in battery, and alternating current power supply still when unsatisfied power supply condition, then can switch to the direct current power supply. The alternating current power supply, the built-in storage battery and the direct current power supply are integrated in the power supply module, and flexible switching can be performed according to whether power supply conditions are met, so that the power supply stability is guaranteed as much as possible.
