Abstract
The utility model provides a redundancy power supply provided with an alarm device, belonging to the computer power supply technical field. A power circuit is connected with a light alarm circuit and a sound alarm circuit; the light alarm circuit is formed as follows: a +12V power circuit is in serial connection with a resistor and a diode, and a +5V SB power circuit is in serial connection with another resistor and another diode, and the two circuits are connected in parallel and connected with an LED in series; the sound alarm circuit is formed as follows: the redundancy power supply is provided inside with a buzzer, and the power circuit, the buzzer and a triode of the redundancy power supply are connected in series, and the triode is also connected with a resistor in series and then connected with two power supply PG signals in series, and the two power supply PG signals are connected with a diode in series respectively. The redundancy power supply of the utility model has the advantages of realizing the light alarm function as well as the sound alarm function and being capable of judging the power supply failure of the redundancy power supply in first time, so that the maintenance of the power supply is convenient, and the normal operation of equipment such as computers can be guaranteed.
Description
1, technical field
The utility model relates to the computer power supply technical field, specifically a kind of redundant power with warning device.
2, background technology
General redundant power, when a power supply broke down, another power supply will be born all loads automatically.Yet after some power supplys broke down, being difficult in time and accurately judge was that fault has appearred in concrete that road power supply, does the maintenance and inspection work of loaded down with trivial details power-supply device after majority also needs to shut down again.And transfer at equipment and can't give the user with tangible warning or caution when utilizing another power supply, so the user can not understand the operating state that power supply is provided with timely, grasps the ruuning situation of machine integral body.Device that can add on redundant power reports to the police indicates class or device have been present stage, and the production industry of redundant power has a technical problem to be solved.
3, summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, and a kind of redundant power with warning device is provided.
The technical solution of the utility model realizes in the following manner, a kind of redundant power with warning device, on power circuit, be connected with optical alarm circuit and sound warning circuit, optical alarm circuit is+12V power circuit and resistance and diode be in series, + 5VSB power circuit and another resistance and another diode are in series, and connect with a light-emitting diode after the parallel connection of two-way circuit again; The audible alarm circuit is to be provided with buzzer in the inside of redundant power, the power circuit of redundant power, buzzer and triode serial connection, triode is also connected with the two-way power supply PG signal of parallel connection after also being serially connected with a resistance, and two-way power supply PG signal also is serially connected with diode respectively.
The utility model has the advantages that:
A kind of redundant power with warning device of the present utility model has utilized the characteristic of diode and triode to be applied on the power supply, both realized the light warning function, realize having the sound warning function again simultaneously, can judge the power failure of redundant power the very first time, thereby convenient maintenance is to keep the operate as normal of equipment such as computer.
4, description of drawings
Accompanying drawing 1 is an electrical block diagram of the present utility model.
Mark in the accompanying drawing 1 is represented respectively;
Power circuit 1, optical alarm circuit 2, audible alarm circuit 3.
5, embodiment
Do following detailed description the in detail below in conjunction with 1 pair of a kind of redundant power of the present utility model of accompanying drawing with warning device:
As shown in Figure 1, a kind of redundant power with warning device of the present utility model is connected with optical alarm circuit 2 and sound warning circuit 3 on power circuit 1, wherein:
Optical alarm circuit 2 is+12V power circuit and resistance and diode be in series, + 5VSB power circuit and another resistance and another diode are in series, connect with a light-emitting diode again after the parallel connection of two-way circuit, light-emitting diode plays a part indicator light, indicator light has 3 kinds of operating states: 1. do not power up or power supply bad, indicator light display white (not working); 2. power supply+5VSB output is normal, and indicator light shows crocus; 3. each group output normal (that is power work is normal) of power supply, indicator light shows green.When powering up or power up the back power supply and do not break down, so+5VSB and+12V does not all export (being 0V), so indicator light (D3) does not work display white; When switching on but not dragging down PSON ,+12V voltage is 0, and+5VSB output 5V voltage drives D3 through R2, D2, shows crocus; After energising and dragging down PSON ,+12V output 12V voltage ,+5VSB output 5V voltage, but because the buffer action of D1, D2 ,+12V voltage drives D3 through R1, D1, shows green.
Audible alarm circuit 3 is to be provided with buzzer in the inside of redundant power, the power supply power circuit of redundant power, buzzer and triode serial connection, triode is also connected with the two-way power supply PG signal of parallel connection after also being serially connected with a resistance, and two-way power supply PG signal also is serially connected with diode respectively.PG1 and PG2 are the clock signal of power supply, and when PG1 or PG2 were high level, buzzer did not ring, and as PG1 or PG2 when being low level, the base stage of the triode of control is a low level, the triode conducting, and buzzer sends sound.When power supply went wrong, when delaying machine, PG1 or PG2 were low level, are high level during operate as normal.Utilize this principle just can design alarm circuit power supply generation abnormal conditions are carried out alarm.
