TW583810B - Method of using voltage-drop rate to measure battery in UPS system - Google Patents

Abstract

In order to assure that the work machine can maintain continuously at the normal state when power is terminated or jumped out, it is necessary to dispose one UPS system to provide power at short period after the power is jumped out and before the delivery of power from the power generator. In order to make the UPS system operate normally, each battery state must be measured irregularly. Therefore, in addition to measuring the variations of voltage and temperature of battery through the use of microprocessor, sensor, and digital converter in the invention, the variation value of voltage drop with time during the discharge procedure of battery is measured such that the measurement of voltage drop rate is used to as a standard to judge whether a battery is suitable for use in UPS.

Correction The factory often suffers from 24k ^ 583810 due to the poor power supply quality, such as the sudden drop in voltage, power failure without warning, etc. V. Description of the invention (1) Loss. In order to avoid losses, most factories construct independent power generation. In the event of a problem, the independent power generation system will start from the start to supply the required power. The power supply will have a window period, and there will be no power supply to stop it. For the occurrence, currently, continuous power system failures are used until the independent power generation system is delivered. It has power storage and instantaneous discharge functions, which can be used to supply equipment. If most of the power is supplied. Therefore, the construction of the uninterrupted power system is completed. Eliminate the electrical system caused by poor power quality. When power is supplied The power system is immediately activated. Because it takes a certain amount of time for independent power generation, the production line still has a very short period of time, which compensates for the above-mentioned empty window period of power supply in order to respond to the empty window period of power supply from the normal power generation system. Although a battery can not store enough batteries for series and parallel connection, it can increase the system. Most of the batteries are connected in series and parallel. There are many important tools in the general factory area as the load. A group of uninterruptible power system to cut off the system contains a lot of batteries and the number is formed by the load host's power demand or when the power supply is normal and the uninterruptible system situation occurs, the uninterruptible system loads the power required by the host instantaneously. Load host The battery pack of the uninterruptible power system needs to be provided. In order to ensure the stability of the uninterruptible power system, this is the case for the uninterruptible power system. After the power supply is lost, each negative provides enough power. Not every battery pack. The battery characteristics of this battery pack vary. The system is in a charging state. When the power abnormally changes to the discharging state, its normal working voltage is immediately supplied, so a sufficient voltage is supplied to the host. ’So generally using a negative

583810 Case No. 91119221 Amendment V. Description of the invention (2) All minor abnormal voltages on the mains voltage of the loader. If abnormal, replace the abnormal normal supply negative. Normal abnormal battery temperature is too high or too high. Use manual measurement for more time. Therefore, the use of automata, such as the device, also exceeds the pressure or temperature. Such as the patent, it can be measured. However, in order to respond to the problem, the power supply of the trip generator is not safe. If the charging state is safe (dV / dt), the system cannot be used to test the battery level of the precision industry. In response to the demand for more pools, in order to increase the system's regular battery, the host ’s power is still loaded for a long time. Most of the criteria are based on the high and low voltage. The method of continuously detecting the charging requires a large number of methods. You can set the temperature or electricity preset value and issue a telegram number 4 3 7 1 1 5. When the battery parameters and the requirements of the police precision industry are described, the uninterruptible power system needs sufficient power and needs a voltage range, but V is the voltage, t In order to maintain sufficient requirements for a period of time, the voltage and current of the battery are still the voltage drop of the upper and lower batteries. In view of this, the reliability of the battery will cause electricity or excessive power. "Telegram, in addition to keeping the low, the current pool of electricity is a low limit. The normal pool group function has a very short time and a certain discharge time.) Excessive power Battery abnormal rate limit as a judge with the charge of this creation is the battery pack to avoid possible. However, if the battery voltage is insufficient and the voltage and source are detected when there is no charge, the device should be used to alert the control of the process cut-off temperature and analogy. With a detection and warning system, electricity and electricity will be consumed. The pool of the pool is the time required to change the time when the battery has an abnormal condition to provide the load master time. Therefore, the battery battery voltage drop slope will still cause continuous power supply. Battery status in this state. In the past, the battery standards were determined separately.

583810 Modification ^ The detection of the time-declining slope (dv / dt) proposes a method of 噺, the principle of which is briefly described below.

When talking about the large battery, the manufacturer will provide the slope data of the battery's positive 3 time decline. The form of the battery and the load are different; the change curve of the rate is also different. After learning the change curve, an instrument with a storage and calculation function, such as a computer, is built in the measurement structure. When the battery pack in the current power-off system is discharged due to need, the instrument can be used separately: record the individual voltage drop value and the corresponding elapsed time. The two types of data can be calculated by inputting the instrument with the calculation function. Output voltage vs. time drop slope data. This information is compared with the information provided by the manufacturer. When the obtained information is lower than the appropriate ratio of the information provided by the manufacturer, such as 70%, it is determined that the battery needs to be replaced and replaced with a new battery. In order to achieve the above detection principle, the function and configuration of each instrument structured in this case are shown in Figure 1. Related components include: control software (丨 丨),

Main unit (12), main unit module (13), parameter measurement module (14), battery (1 5). The control software functions include setting hardware and software parameters, receiving materials, recording data, calculating data #, issuing warnings, and data query. The host module has a 232 or 485 communication interface to collect parameter measurement modules, which are then processed by the microprocessor and transmitted to the computer. The main unit module also has an LCD liquid: a display, which is used to display the currently set warning parameters and the set parameter measurement module station number. There is also a buzzer that can send out warning carp. The parameter measurement alone converts the measured temperature and voltage by analogy 2 and encodes them by the microprocessor, and then transmits the data through the 232 or 485 communication interface. Host module and parameter measurement

583810 Case No. 91119221, the amendment (4) 'The connection method of the electronic components is as shown in the figure. One module is connected to a voltage, temperature and counting. 5. Description of the invention The above functions are described. Each element is connected, and each battery not only shows the same power. Therefore, the control limit of the battery module in each battery group is connected to the total power area of the battery group. The main unit is connected to the same factory. Every pool. Therefore, to set the station number, the host needs to be connected. All the configurable data on the master of the software installation and connection will be updated by the module to retrieve the software. The new time set by the module is based on the current and different information from each host. It can be connected to provide a display dielectric pressure limit. Multiple negative power systems require different bits and parameters in the brain. The host computer and the parameter parameters are spaced. The module is profitable and provides a battery room. Due to the amount of parameter battery. There are multiple parameters for the main load surface, and the main load measurement module needs a large number of main measurement modes. The measurement mode can be controlled and the number can be controlled. When the group's general broadcast is currently not shown in this issue. . The parameter is a single measurement module parameter quantity quantity measuring machine jumper setting station display target, so the host module one host machine module group station number multiple masters by the test group display software updates the information protocol method every time the parameters are clear. Parameter measurement and measurement module The load host can set the module and the module to be measured, and the required number and the temperature before the measurement require multiple groups to connect to the module. the Lord . So know. Set the connection mode of the host module on the screen. The control section will act as expected and issue the information that needs to be connected to it. : Therefore, it is not necessary. Module and battery can measure the battery. The same station number table. The host module is connected to the power of the host module. Parameters above and below main and voltage. Because the motor module of the UPS system can also be connected to each battery pack separately. Will be heading. The parameters of the data connection between the host software and the computer will be set before the main control of the computer can be set, the number of control pool connection

Data is stored =, the time at that time is also recorded. The recorded voltage and the corresponding time after the battery is discharged are important voltages used to determine whether the battery is abnormal. The voltage value in the database can be calculated by calculating the voltage versus time of each battery in the factory during charging and discharging. Rate of change (or software for slope system pre-built by the battery manufacturer to test the normal battery = voltage and load change data. You can use the comparison voltage to time slope to understand whether the battery Mf condition occurs, the battery station number is for use Or, the battery pack of the uninterruptible power supply system cannot provide normal work during early prevention or replacement and discharge. _% The system can be normally operated at the time of power failure.
