Tambayar da Duk Da Take Nuna Sababin Da Duk Da Ƙasa a Maimaitaccen Kirkiro Tsarin Kula

Waɗannan lokacin, tushen masu sauri na gida suna yi karin yadda ake amfani da su, kuma abubuwa daban-daban da ake iya samun shi a cikin tushen masu sauri suna cika a wajen rarrabe tsari. Wannan makaranta ta nuna sababon da ke faruwar tushen masu sauri, kuma ta bayyana kayayyaki da za su iya yi, tun daga wasu misalai na abubuwan da suka faru a kan tushen masu sauri.

1. Tushen Da Ba Ta Baka
Tushen da ba ta baka yana nufin tushen da ya faruwa amma ba ta baka ba, wanda shi ne mafi yawan faruwar tushen masu sauri a kan harkokin gwamnati. Idan an fito da tushen da suka faru, ana iya samun cewa fadada C2 a kan tafkin DCDC ya faru, kuma chipin da ya kawo kyaukyau a kan tafki ya faru, ko kuma tsafta UN ta fi sani. Sababon da ke faruwar tushen da ba ta baka ba suna nuna haka: faruwar kyaukyau a kan tafki (kamar kawar karami ko faruwar gwamnati) ko kuma harmonikin maye da ake iya samun shi a kan yanayi na harkokin gwamnati zai iya faruwar fadada kuma chipin da suka kawo kyaukyau; idan ba a yi aiki a cikin tsohon tarihi, zai iya faruwar fadada da kuma tsafta UN ta fi sani.

2. Tushen Da Ba Ta Baka Duk
Tushen da ba ta baka duk yana nuna alama da ake iya samun shi a kan LCD da ba ta baka duk. Abubuwan da suka faruwar wannan batu sun haɗa da aiki da ba ta daidai a kan pinna LCD ko kuma tushen da ake fito a kan gwamnati mai karfi da ake iya samun shi a kan karfin matafi. Misali, tushen masu sauri na uku da aka fito a kan gwamnati ta baka jumla na energy da ake iya samun shi a kan 702,610.88 kWh, energy na lokacin da ake iya samun shi a kan 700,451.96 kWh, energy na lokacin da ake iya samun shi a kan 700,987.42 kWh, energy na lokacin da ake iya samun shi a kan 700,551.59 kWh, kuma energy na lokacin da ake iya samun shi a kan 700,619.91 kWh. A cikin yanayi na daidai, jumla na energy da ake iya samun shi ya kamata da sum din lokaci da ake iya samun shi. Amma, wannan hadisi ba ta shiga a kan tushen. Aka baka akwai hanyar barcod a kan LCD ta baka 75517684, amma a kan nameplate ta baka 05517684.

Wannan ya nuna cewa LCD ya baka duk, inda ake iya samun "0" a kan "7", wanda ya tabbatar da tushen da ba ta baka duk. Idan an karɓe tushen a kan gwamnati da handheld meter reader, an samun jumla na energy da ake iya samun shi a kan 002,610.88 kWh, energy na lokacin da ake iya samun shi a kan 000,451.96 kWh, energy na lokacin da ake iya samun shi a kan 000,987.42 kWh, energy na lokacin da ake iya samun shi a kan 000,551.59 kWh, kuma energy na lokacin da ake iya samun shi a kan 000,619.91 kWh. Sum din lokacin da ake iya samun shi ya shiga da jumla, wanda ya tabbatar da tushen da ba ta baka duk. Sababon da ke faruwar wannan batu ya nuna cewa tushen ya fito a kan gwamnati mai karfi, kuma ya iya samun karfin matafi na karfi.

3. Ba Zan Iya Karɓe Data Na Energy Ba
Wannan batu yana nuna cewa a kan tushen masu sauri, ana iya samun alama ta "←" (wanda ya nuna cewa energy ta shiga), kuma jumla na energy da ake iya samun shi ta baka 0, amma energy na shiga ta baka halaye. Bayanan da aka samu, sababon da ke faruwar wannan batu ya nuna cewa wiring ta tushen ya faru. Energy na daidai ya shiga da energy na shiga. Idan an sanya wiring, tushen ya ji aiki daidai.

4. Under-Voltage Na Battery
Tushen masu sauri na uku da kuma tushen masu sauri na uku suna da battery na tafki wanda ya kawo kyaukyau a kan chipin na tafki. Tushen masu sauri na uku suna da battery na tafki wanda ya kawo kyaukyau a kan programming door a kan tushen. Idan an faru batu na under-voltage, alarm light na tushen ya ci gaba, kuma a kan LCD ana iya samun alama na low-power. A kan gwamnati, ana iya fito battery, kuma a tuntuƙi voltage a kan positive da negative terminals ta battery da DC voltmeter. Idan voltage ya shiga da specifications, battery ya ci gaba a tafki kuma a yi aiki daidai; idan voltage ya ɗaya da rated value, battery ya ci gaba a tafki.

5. Fast Registering (Over-registering)
Tushen masu sauri na uku da aka fito a kan gwamnati ta baka jumla na energy da ake iya samun shi. Akan testing a kan gwamnati da calibration instrument, an samun cewa tushen ya shiga da error limits. Testing a kan laboratory ta tabbatar da tushen ya shiga da standards, amma reading pre-calibration ta baka 4,505.21 kWh kuma reading post-calibration ta baka 4,512.32 kWh—wanda ya nuna cewa 7.111 kWh ya faru a kan testing, amma tushen masu sauri na uku daidai ya faru kawai kusan 1 kWh. Wannan ya tabbatar da batu na "fast registering."
Analysis ya nuna cewa CPU supply voltage ya shiga da designed 5V, wanda ya faruwar read/write operations a kan I2C bus. Tun daga inspection a kan tafki, ana iya samun cewa fadada C2 ta faru. Sababon da ke faruwar fadada sun haɗa da high voltages na grid fluctuations ko kuma kawar karami, kuma harmonikin maye da ake iya samun shi a kan yanayi na harkokin gwamnati.

6. Comprehensive Analysis
Tushen masu sauri suna da muhimmanci masu sauri, kuma suna da muhimmiyar aiki da ake iya samun shi a kan tushen, aiki da ake iya samun shi a kan tushen, monitoring na lokacin, automatic control, kuma data interaction. Suna da muhimmiyar aiki da ake iya samun shi a kan tushen, marketing management, kuma customer service. Amma, muhimmin aiki mafi muhimmanci shine accurate energy measurement, wanda ya kamata daidai da stability. Saboda haka, a cikin yadda ake amfani da systems na energy acquisition don monitor operational status da abnormal events na tushen masu sauri, ita ce amsa a yi analysis of root causes of meter failures and actively implement improvement measures.

Tun daga analysis of operational fault cases, sababon da ke faruwar meter failures suna nuna haka:

(1) Environmental influences, including electromagnetic interference, harmonics, high voltage, lightning strikes, electrostatic discharge, excessive temperature and humidity, high-frequency electromagnetic fields, and electrical fast transient (EFT) pulses.

(2) Poor component quality, including batteries, CPUs, LCD screens, relays, varistors, capacitors, metering chips, voltage regulators, clock chips, crystals, 485 optocoupler diodes, and carrier communication modules.

(3) Software faults, including system crashes, sudden changes in energy display, and clock errors.

(4) Workmanship issues, including substandard welding techniques by meter manufacturers (leading to cold or loose solder joints) and incorrect wiring during installation by power supply companies.

To address these failure causes, the following measures can be taken:

(1) Strengthen component selection to ensure smart meters operate reliably even under extreme environmental conditions.

(2) Enhance software testing to improve the software's error prevention and anti-interference capabilities.

(3) Improve quality supervision of workmanship, effectively monitoring and evaluating both internal assembly quality and on-site installation practices.
