Block 2.4 in the sixth figure is the circuit diagram of the power measurement unit of the author. The figure shows two sets of power measurement units. There are 12 power measurement units in this creation, so it is necessary to have 6 measurement boards such as block 2.4 to form The requirements of this creative embodiment. Taking one of them as an example, each group of power measurement units consists of three integrated circuits (1C), namely U19 dedicated microprocessor, 9 M425447 U20 memory and U21 power measurement 1 (3, in the figure The selected input voltage signal is input from the V-IN1 pin to the PIN-7 pin of U21 measuring 1C, and the common reference zero potential is taken as AGND. The measured current signals V1P-1 and V1N-1 are detected in the current. The conversion voltage can be obtained on the resistor R53, and its voltage is proportional to the current to be measured. U21 power measurement 1 (: according to the input voltage and current signal ' can get the voltage value, current value and power value to be measured. Accumulated electric energy value and power factor, frequency and other power information. U19 is a special microprocessor for the module that can read the value measured by U21 and correct it according to the correction parameters stored in U20. Accurate data, the calculated results are stored in U20 memory, U20 also has correction parameters, still retain memory when shutting down, and can control the power of the power measurement IC (U21), when the microprocessor U19 finds communication with U21. Or when the measured value is abnormal, The power supply is restarted by controlling Q1 to improve the reliability of use. Each dedicated power measurement unit communicates with the microprocessor of block 2.5 through TXD and RXD signals to obtain measurement information of each power measurement unit. Block 2.5 is the microprocessor circuit diagram of the author. The U5 microprocessor plans two sets of serial communication interfaces (UART), which are the MTXD and MRXD signals for each measurement unit, and the STXD and SRXD signals for external communication. The MTXD is connected to the TXD1~TXD12 of the power measurement unit, here is the switch 1C through U15 and U16, that is, the microprocessor U5 is decoded via the address line of ADDRO~ADDR4 so that the MTXD can be correspondingly connected to each power measurement. The unit's TXD signal is also switched to 1C' by U17 and U18. The MRXD can be connected to the RXD signal of each power measurement unit. In other words, the U5 microprocessor ic can communicate with each measurement unit in turn through the multiplexed scan M425447. Set or read the data, then use the U10 RS-485 conversion 1C link of STXD and SRXD and block 2.6 communication interface circuit, U10RS-485 conversion 1C can STXD and SRX The D digital signal becomes a differential RS-485-A and RS-WB signal, which can be connected with a remote central collection server to achieve remote monitoring of the power consumption information of each circuit of the distribution box. # U5U处理II There is an important task, that is, the information measured by each loop 'matching the contents set in each loop can do the necessary process, operation' such as phasor addition, algebra addition, etc. in order to achieve the power measurement unit It is planned to be a single and three-phase power monitoring function, and any combination of multiple groups can be used to complete complex and unpredictable power monitoring needs. In addition, the power supply required for this creation is also provided in J3-7 and 8 of block 2.6. If the picture is not 24V and 24-0V, the external supply mDC power supply must first be regulated by U13 power supply 1C in block 2.7. Conversion, you can get a stable 5V working power supply, in addition to improve the reliability of the overall monitoring, specially set up a power monitoring ICU14, the power monitoring IC can detect the 5V power supply at any time, when the 5 V power supply is instantaneously or slowly falling to When only about left and right are left, a positive pulse will be generated on the PWR pin. The positive pulse signal will turn off the 5V power supply after the power supply 1C is turned off, and then restart the power after the positive pulse signal disappears. In addition, the WDI pin of U14 is connected to an output pin of the microprocessor of U5, and the pulse signal input must be generated by the program timing. Therefore, if the microprocessor of U5 is privately crashed, or U5 reads the abnormality of each power measurement unit, The pulse signal can be paused by the WDI pin, which can cause the positive pulse signal to restart the power supply, increasing the reliability of use. The block 2.8 of the eighth figure is the circuit diagram of the touch operation interface of the present invention. The M425447 U11 is a capacitive touch detection ic, wherein KEY1~KEY4 are four touch pieces, which are installed under the outer casing, and the human hand is close to the KEY- The touchpad of 1~KEY-4 generates a capacitance change, so that U11 can distinguish the button signal to be operated at the moment, and then output the micro-processing IC U5 of the block 2.5 in a digital manner, that is, KEY-UP and KEY- in the circuit diagram. DOWN, KEY-CYCLE and KEY-SET Four digital logic signals, U5 can perform the information to be displayed and the content to be set according to the information input. In the figure, the capacitors C11, C12, C14, and C15 connected in parallel with the touch lens can adjust the touch k degree, and the less the capacitance, the better the sensitivity. Lu Box 2.9 is the information display circuit diagram of the creation. In the figure, LD1, LD10, LD15, LD23, LD24, LD25 are 6 LED seven-segment displays, which can display the digital and simple English letters ABCD, and the LEDs of each segment are subject to The series of Ul, U3, U6, U8, U9, and U12 are rotated in parallel with 1C to drive; in other words, the microprocessor IC U5 of block 2.5 can pass four signal lines such as DATA, STR, CLK, and PWM, and then serially and serially Ic illuminates the contents of the seven-segment LEDs to be illuminated one by one to display the information content to be displayed, and the PWM pin can control the ON/OFF ratio of the LED driving power source that is lit to achieve the purpose of controlling the brightness. In addition, U2, U4, and U7 are also serially connected to the parallel 1C, which is controlled by the four signal lines mentioned above, except that the LEDs that are lit are separate indicator lights, such as LD2~LD9, LD11~LD14 'LD16~ LD22, etc. These indicators are used to give the user a clearer view of the project and loop relationship displayed, as well as the project content set.
