Abstract
The invention provides a PDU (power distribution unit) power supply with an alarm function. The PDU power supply comprises a PDU power supply circuit, and is characterized by also comprising a monitoring module and an alarm module, wherein both the monitoring module and the alarm module are connected with the PDU power supply circuit, and the monitoring module is electrically connected with the alarm module. The PDU power supply has the benefits that the monitoring module can be used for monitoring the voltage and current values of the circuit at any time, the alarm module can be used for sending out an alarm to prompt a staff when the bearing capacity of the circuit is exceeded, and the safety performance is relatively high.
Description
Technical field
The present invention relates to a kind of PDU electric power source distribution device, especially relate to a kind of PDU power supply with alarm function.
Background technology
Along with computer networking technology development, the demand of the key equipments such as server, switch, various electronic equipments also increases day by day.PDU, plays a part all expensive device in associated machine room and runs well for each electrical equipment in these information network system machine rooms provides the product of distributing electric power as special.The PDU power supply of prior art exists protection not enough, and the technical matters such as alarm in time while being in an emergency.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of PDU power supply with alarm function, be especially applicable to power consumption large, to security performance, require high information network system machine room to use.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of PDU power supply with alarm function, comprise PDU power circuit, it is characterized in that: also comprise monitoring modular and alarm modules, described monitoring modular is all connected with described PDU power circuit with described alarm modules, and described monitoring modular is electrically connected to alarm modules.Described monitoring modular comprises a voltage receptor, a current-sense device and a liquid crystal display; One end of described voltage receptor is connected with described PDU power circuit, and the other end is connected with liquid crystal display; Described current-sense device is connected with described PDU power circuit, described liquid crystal display and described alarm modules simultaneously; Described liquid crystal display can show magnitude of voltage and the current value of current circuit.Described alarm modules comprises the pilot lamp of a hummer and three kinds of different colours, and the pilot lamp of described three kinds of different colours is respectively: green indicating lamp, orange indicating light and red led.The pilot lamp of described hummer and described three kinds of different colours is all connected with described current-sense device.
Advantage and good effect that the present invention has are: owing to adopting technique scheme, because this PDU power supply is provided with alarm modules, once load surpasses the load-bearing capacity of circuit, can send in time alerting signal, prompting staff safeguards, avoids causing the generation of follow-up dangerous situation.Have simple in structure, the advantage such as security performance is high, protection is large.

Embodiment
As shown in Figure 1, the present invention includes switch control module, PDU power circuit, output module, monitoring modular and alarm modules.Described monitoring modular is all connected with described PDU power circuit with described alarm modules, and described monitoring modular is electrically connected to alarm modules.
As shown in Figure 2, described switch control module is connected with PDU power switch 1.Described output module is connected with socket 7.Described monitoring modular comprises a voltage receptor, a current-sense device and a liquid crystal display 6; One end of described voltage receptor is connected with described PDU power circuit, and the other end is connected with liquid crystal display 6; Described current-sense device is connected with described PDU power circuit, described liquid crystal display 6 and described alarm modules simultaneously; Described liquid crystal display 6 can show magnitude of voltage and the current value of current circuit.Described alarm modules comprises the pilot lamp of a hummer 5 and three kind of different colours, and the pilot lamp of described three kinds of different colours is respectively: green indicating lamp 2, orange indicating light 3 and red led 4.The pilot lamp of described hummer 5 and described three kinds of different colours is all connected with described current-sense device.Described liquid crystal display 6 is located at PDU power supply surface.
When PDU normally works, the current data that described current-sense device collects, in normal range, only has green indicating lamp 2 to light; When the current data collecting when described current-sense device approaches preset alarm threshold value, only there is orange indicating light 3 to light; When the data that collect when described current-sense device surpass preset alarm threshold value, only have red led 4 to light, described hummer 5 alerting signal of sounding simultaneously, to point out staff.
In the present embodiment, this preset alarm threshold value is 20A.PDU when work, when the current data collecting when described current-sense device is less than 18A, only there is green indicating lamp 2 to light; When the current data collecting when described current-sense device is greater than 18A and is less than 20A, only there is orange indicating light 3 to light, remind staff to note; When the current data collecting when described current-sense device is more than or equal to 20A, only have red led 4 to light, hummer 5 alerting signal of sounding simultaneously, to point out staff.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
