Problems solved by technology

[0002] The current centrifuge unit does not have a quick start function. If you need to start the centrifuge unit quickly, when the power is turned on again after a power failure, manual operation is required to modify the unit parameters and eliminate the fault, so as to achieve the purpose of restarting the unit. The disadvantage is that the unit cannot realize automatic Start up, and manual operation is required when restarting after power failure
Especially after the power failure, the working parameters of the unit are lost, and the operator needs to reset the new working parameters according to the immediate load of the unit. On the one hand, it is troublesome, and on the other hand, there may be a mismatch between the newly set working parameters and the current working load of the unit. Happening

Embodiment 1

[0036] Embodiment 1. A method for automatic quick start-up of a unit when power is off. The following will combine figure 1 A method for automatic quick start-up of a power unit in this embodiment is introduced in detail.

[0037] Such as figure 1 As shown, a method for automatic and quick start-up of a unit after power failure comprises the following steps:

[0038] Step 1: Detect the operating status of the unit, and record the operating parameters of the unit at the moment of power failure when the unit is powered off;

[0039] Step 2: When the unit is powered on, eliminate the power failure and enter the fast start stage;

[0040] Step 3: When the real-time working parameters of the unit reach the operating parameters at the moment of power failure, the quick start-up phase is ended and the normal operating state is entered.

[0041] In this embodiment, the specific implementation of judging whether the unit is in a power-off state in step 1 is: when the unit is shut d...

Embodiment 2

[0050] Embodiment 2. An automatic and quick start-up system when the unit is powered off. The following will combine figure 2 A system for automatic and quick start-up when the unit is powered off in this embodiment is introduced in detail.

[0051] Such as figure 2 As shown in the figure, an automatic quick-start system for unit power failure includes a power failure identification module and a main control module. The power-off identification module is used to detect the unit operating state of the unit; the main control module is used to record the operating parameters of the unit at the moment of power-off when the unit is powered off; it is also used to eliminate the power-off fault when the unit is powered on, and Enter the fast start stage; when the real-time working parameters of the unit reach the operating parameters at the moment of power failure, the fast start stage ends and enters the normal operation state.

[0052] In this embodiment, the power failure ide...

Abstract

The invention relates to a method and a system for automatic and quick start for power-off of a unit as well as an air conditioner. The method comprises steps as follows: the operation state of a unit is detected, and operation parameters of the unit at the moment of power-off are recorded when the unit is powered off; when the unit is powered on, power-off faults are eliminated, and the unit enters the quick start phase; and when real-time working parameters of the unit reach the operation parameters at the moment of power-off, the quick start phase is ended, and the unit enters the normal operation state. With the method and the system, the function of automatic and quick start after power-off is increased, and the unit automatically enters the quick start phase under the conditions that the power-off time and the unit power-on temperature after power-on meet preset start conditions, so that the unit reaches the working parameters at the moment of power-off again, the restart time after power-off of the unit is shortened, and the load of the unit is prevented from fluctuating.

Description

technical field [0001] The invention relates to the technical field of electrical automation control, in particular to a method, a system and an air conditioner for automatically and quickly starting a unit when power is off. Background technique [0002] The current centrifuge unit does not have a quick start function. If you need to start the centrifuge unit quickly, when the power is turned on again after a power failure, manual operation is required to modify the unit parameters and eliminate the fault, so as to achieve the purpose of restarting the unit. The disadvantage is that the unit cannot realize automatic Start up, and manual operation is required when powering off and restarting. Especially after the power failure, the working parameters of the unit are lost, and the operator needs to reset the new working parameters according to the immediate load of the unit. On the one hand, it is troublesome, and on the other hand, there may be a mismatch between the newly s...
