Button is used to departing from first module to second unit when being used alone, and artificial key-press input is setting its running parameter.Power supply is single
Unit 26 provides power supply for the second host computer, is connected with relay 24 on the second host computer 22 and provides battery for the device
The normally closed and normally opened output point of group internal resistance value off-limit alarm, signal occurs to detect that circuit 25 provides battery pack internal resistance and exists for the device
The measurement point of line monitoring.
Further, the second unit also includes that built-in electric capacity C, the electric capacity C are connected in series with detection sensor.
Electric capacity C plays a part of protection circuit to the second unit, and during cut-off direct current drive circuit electric current can also be met
Change, it is to avoid the coupled interference between circuit.
The working method one of the device：Second unit can be linked together composition with first module by communication interface 14
One system is realizing the on-line monitoring of back-up source battery pack internal resistance value.Working method two：Second unit can also independent structure
The on-line monitoring work of back-up source battery pack internal resistance value is realized into a system, the purpose of design work mode one is can
With by the parameters in the plant running, by first module of the installation by adhering in back-up source cabinet cabinet door come all aobvious
Illustrate and, meanwhile, user just can be operated parameter setting without opening back-up source cabinet cabinet door to the device.This side
Formula is commonly available to be adopted in the manufacture process before back-up source cabinet dispatches from the factory.If will be to after user's onsite application
If stand-by power source cabinet is installed additional, for ease of site operation, working method two can be adopted, it is not necessary to the scene in back-up source cabinet door
Punch construction, and unit 2 is directly arranged on the inside of back-up source switch board or battery rack.
Embodiment 1：Direct current cabinet is usually as electric power and the corollary equipment of industrial enterprise's high pressure switch cubicle, its application purpose
It is that, when forced outage, direct current cabinet can provide 220V direct current operative power sources to high pressure switch cubicle.Therefore each DC cabinet
It is furnished with a set of battery pack, for providing back-up source.When needing battery pack to provide back-up source, it may appear that three kinds of situations：1.
Battery pack normal power supply, direct current cabinet is working properly；2. the situation of open circuit is had in the middle of battery pack, and now battery pack cannot be normal
Power supply, direct current cabinet job failure, high pressure switch cubicle is without operation power, danger close；3. battery pack internal resistance is larger, when offer standby
During electric current, due to electric current it is very big so that internal battery pack moment generates heat, and causes apparatus overheat even fire.Therefore, direct current cabinet peace
The device real-time monitoring battery pack internal resistance resistance disclosed in dress the utility model is highly desirable to.Direct current cabinet is installed using this dress
Put very simple, using the working method two of this device, the second unit of the device is arranged on into the conjunction inside direct current cabinet

The "+" of back-up source battery pack, "-" pole are connected, then by the 220VAC power on of battery pack internal resistance on-Line Monitor Device, immediately
Real-time monitoring can be carried out to the battery pack internal resistance of direct current cabinet, if monitored internal resistance value is exceeded, " back-up source battery pack internal resistance
On-Line Monitor Device " will report to the police immediately.
Embodiment 2：The device is implemented into on-line monitoring application to the battery pack internal resistance of UPS using working method one real
Example.UPS uninterrupted power sources are important supporting usually as the industries such as finance, industrial enterprise's instrument system, bank, airport, hospital
Equipment, its application purpose is that, when forced outage, UPS uninterrupted power sources can persistently provide the power supply of 220VAC or 380VAC,
So as to ensure the normal work of these key sector's equipment.Each UPS uninterrupted power source is equipped with a set of battery pack, for providing
Back-up source.When needing battery pack to provide back-up source, it may appear that three kinds of situations：1. battery pack normal power supply, UPS is uninterrupted
Power work is normal；2. have the situation of open circuit in the middle of battery pack, now battery pack cannot normal power supply, UPS is uninterruptedly electric
Source job failure, needs the visual plant power-off of continuous powered operation；3. battery pack internal resistance is larger, when standby electric current is provided,
Due to electric current it is very big so that internal battery pack moment generate heat, cause UPS no-break power units overheated or even fire.Therefore,
UPS uninterrupted power sources install the device and carry out real-time monitoring battery pack internal resistance resistance and are highly desirable to.UPS uninterrupted power sources are installed
It is very easy to using the device, the first module of the device is arranged on the cabinet door correct position of UPS uninterrupted power source cabinets, just
In operating personnel's button operation.The second unit of the device is arranged on into the correct position inside UPS uninterrupted power source cabinets, then will
By the monitor input terminal of battery pack internal resistance on-Line Monitor Device (i.e. detection sensor 27) respectively with back-up source battery pack
"+", "-" pole are connected, then by the first module of battery pack internal resistance on-Line Monitor Device and the 220VAC power on of second unit,
Real-time monitoring can be carried out to the battery pack internal resistance of UPS uninterrupted power sources immediately, if monitored internal resistance value is exceeded, the device will
Report to the police immediately.
The above, only the utility model preferably specific embodiment, but protection domain of the present utility model is not
Be confined to this, any those familiar with the art in the technical scope that the utility model is disclosed, according to this practicality
New technical scheme and its utility model design in addition equivalent or change, all should cover in protection model of the present utility model
Within enclosing.
