Embodiment Construction

[0011] The accompanying drawings disclose the specific structure of the present invention without limitation, and the present invention will be further described below in conjunction with the accompanying drawings.

[0012] Such as figure 1 As shown, the dual power switch control device includes a control unit and an execution unit. The control unit includes a DSP processor, a control loop A and a control loop B. The control loop A detects the voltage, frequency and phase of the common power supply in real time, and Send the real-time signal to the DSP processor. After the DSP processor judges the real-time signal, it sends the corresponding operation command to the execution unit to control the on and off of the common power supply; the control loop B is connected to the DSP processor and controls the backup Power on and off; the common power supply and the backup power supply are interlocked, and when one of them is turned on, the other is automatically turned off. The exec...

Abstract

The invention discloses a double-power switch control device which comprises a control unit and an execution unit, wherein the control unit comprises a DSP (digital signal processor), a control loop A and a control loop B; the control loop A is used for detecting voltage, frequency and phase position of a frequently-used power supply in real time and sending real-time signals to the DSP; after the real-time signals are judged by the DSP, corresponding operating orders are sent to the execution unit to control the switch-on and switch-off of the frequently-used power supply; the control loop B is connected with the DSP so as to control the switch-on and switch-off of a stand-by power supply; the frequently-used power supply and the stand-by power supply are in interlocking relation, namely, one of the power supplies is switched on, while the other is automatically switched off. According to the invention, the characteristics of high speed, high precision and powerful functions of the DSP are utilized, the stable, reliable and quick switch of the double-power switch is realized and the continuous, uninterrupted safe power supply is ensured; as the switch is switched manually, the control is diversified.

Description

technical field [0001] The invention relates to a power switch control system, in particular to a dual power switch control device. Background technique [0002] With the advancement of science and technology and the development of society, people's living standards continue to improve, and various industries have put forward higher and higher requirements for the reliability, safety, and continuity of power supply. In many occasions, two-way power supplies are required to ensure power supply. reliability and continuity. For example, shopping malls, banks, hospitals, communication departments, transportation departments, and national defense and military departments all require continuous and uninterrupted safe power supply. The intelligent dual power switch controller can solve the above problems well and provide a strong guarantee for reliable and continuous power supply. At present, intelligent dual-power switch controllers are used in many enterprises and fields. With ...
