Description of drawings
Fig. 1 is the schematic diagram of the utility model accumulator safety on line monitoring device.
Embodiment
Embodiment below in conjunction with description of drawings the utility model.
As shown in Figure 1; Electric substation's accumulator safety on line monitoring device of the utility model; It is characterized in that by single-chip microcomputer; The relay control circuit, accumulator testing loop, display, keyboard, the PC that are connected of single-chip microcomputer formed therewith respectively, and described PC is connected with described single-chip microcomputer with the CAN bus through the RS485 interface, and described single-chip microcomputer, relay control circuit, accumulator testing loop composition data are gathered and key-course; Described single-chip microcomputer, CAN bus, PC composition data transport layer are provided with data analysis layer in the described PC.
Described PC is the user terminal PC.
Described accumulator testing loop comprises battery tension test loop, accumulator internal resistance test loop, accumulator dump energy test loop.
This accumulator safety on line monitoring device can be divided into three parts, is respectively data acquisition and control loop layer, data transfer layer and is positioned at the data analysis layer on the user terminal PC.
The user starts preset test event through the Single-chip Controlling relay circuit, comprises measuring voltage, electric current; Control loop injects the AC signal of certain frequency simultaneously to accumulator, because there is impedance in internal, measure the current signal of its feedback then, carries out signal Processing, relatively injects the difference of signal and feedback signal, thereby records accumulator internal resistance.
Single-chip microcomputer is when these data presentation are on LCDs, extract integrate effective battery real time data via RS485 interface and CAN bus transfer to PC.
Accumulator monitoring software can show battery pack total voltage, sample rate current, dump energy and accumulation electric weight, and the battery rated capacity of current battery pack also can be set, and the prediction dump energy.Mutual relationship in the real-time tendency curve embodiment charge and discharge process between total voltage and the charging or discharging current.
The single battery voltage value and the internal resistance value that can also show every joint accumulator respectively.Single battery voltage is patrolled and examined process and is adopted the real-time sampling mode, and sampling time interval is 50 ms.Because it is less that the internal resistance of accumulator changes at short notice, especially in charging process, so accumulator internal resistance is patrolled and examined the employing dual mode: periodic sampling mode and manual sample mode.Through clicking internal resistance monitoring option,, the internal resistance parameter fills in the collection period time in being provided with, and device will be patrolled and examined by this setting value loop cycle, perhaps click the button of sampling immediately and realize manually patrolling and examining.
Monitoring through internal resistance can be carried out reliable prediction to the performance of battery, and realizes in time reporting to the police through configuration software, in order to avoid accident occurs.
