PWM Controller and Transformer Driver with Quad-Channel Isolators ADUM3474ARSZ

GENERAL DESCRIPTION The ADuM3470/ADuM3471/ADuM3472/ADuM3473/ ADuM3474 devices1 are quad-channel digital isolators with an integrated PWM controller and transformer driver for an isolated dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler® technology, the dc-to-dc converter provides up to 2 W of regulated, isolated power at 3.3 V to 24 V from a 5.0 V input supply or from a 3.3 V supply. This eliminates the need for a separate, isolated dc-to-dc converter in 2 W isolated designs. The iCoupler chip scale transformer technology is used to isolate the logic signals, and the integrated transformer driver with isolated secondary side control provides higher efficiency for the isolated dc-to-dc converter. The result is a small form factor, total isolation solution. The ADuM347x isolators provide four independent isolation channels in a variety of channel configurations and data rates.

Η Τεχνολογία Της Control4 Πίσω Απο Το Πρωτόκολλο Λειτουργίας Της.

Πρωτόκολλο λειτουργίας της Control4

Τα προϊόντα της Control4 που παρουσιάστηκαν για πρώτη φορά στην εμπορική έκθεση οικιακής τεχνολογίας CEDIA το 2004, ήταν οι πρωταγωνιστές της ευέλικτης επικοινωνίας. Η τεχνική ομάδα της Control4 διαπίστωσε την ευελιξία που προσφέρει η ασφαλής ασύρματη επικοινωνία, και τροποποίησε τη λογική σύνδεσης των συστημάτων της, ελαχιστοποιώντας την ανάγκη εργασιών επισκευής και επιδιορθώσεων. Είναι η πρώτη εταιρία που σύζευξε το ενσύρματο και ασύρματο δίκτυο Ethernet, με την επαναστατική ασύρματη τεχνολογία ZigΒee Pro και το καλωδιακό RS485 σε έναν ενιαίο κορμό λειτουργίας. Ενοποίησε όλους τους σύγχρονους τρόπους σύνδεσης και διαχώρισε κάθε συσκευή της να επικοινωνεί με την ασφαλέστερη και ταχύτερη μέθοδο.

Οπότε όλα τα υλικά που εγκαθίστανται εντός ηλεκτρολογικών πινάκων (dimmers, relays κλπ.) ή όσα απαιτούν πληροφορία ήχου και εικόνας (όπως οθόνες αφής, μπουτονιέρες θυροτηλεόρασης κ.α.) επικοινωνούν ενσύρματα μέσω Ethernet και συνδέονται με κλασικό καλώδιο UTP Cat5e ή ανώτερο.

Οι ασύρματες συσκευές που χρησιμοποιούν τακτικά οι χρήστες και απαιτούν ελευθερία κίνησης με ταυτόχρονη μετάδοση πληροφορίας γραφικών, όπως τα τηλεχειριστήρια, οι εφαρμογές, κ.α., χρησιμοποιούν το δίκτυο WiFi.

Οι ενσύρματες συσκευές που συνήθως εντοιχίζονται σε εσωτερικούς χώρους, όπως διακόπτες, μπουτονιέρες κ.α., επικοινωνούν μέσω RS-485 και συνδέονται σε σειρά ή ακτινικά μέσω ενός καλωδίου τεσσάρων συνεστραμμένων αγωγών χαμηλής τάσης 48Volt DC. Οι δυο αγωγοί μεταφέρουν την πληροφορία (Data±), ενώ οι άλλοι δύο την τάση λειτουργίας (DC±).

Οι ασύρματες συσκευές που τοποθετούνται σε σημεία που δεν επιδέχονται εργασίες νέας καλωδίωσης, όπως μπουτονιέρες με ενσωματωμένα relay και dimmer κ.α., επικοινωνούν μέσω ZigΒee Pro* και συνδέονται εντός ενός δικτύου προσωπικής περιοχής (PAN) που ρυθμίζεται να έχει συγκεκριμένη εμβέλεια.

Αυτή η μεγάλη επικοινωνιακή ενοποίηση μετέτρεψε αυτομάτως όλες τις συμβατικές κατοικίες σε υποψήφιες ενσωμάτωσης τεχνολογίας smart home, χωρίς όμως το κόστος εργασιών καλωδίωσης και των συνεπακόλουθων εργασιών επισκευής ή επιδιορθώσεων. Έτσι δημιουργήθηκε ένα νέο άνοιγμα αγοράς που γρήγορα τροφοδοτήθηκε με αντίστοιχα προϊόντα από όλες τις ανταγωνιστικές εταιρίες.

* Το ZigBee είναι μια ασύρματη τεχνολογία βασισμένη στο πρωτόκολλο IEEE 802.15.4 που αναπτύχθηκε στις αρχές της δεκαετίας του 2000 ως μια εναλλακτική λύση χαμηλού κόστους και κατανάλωσης σε σχέση με τα υφιστάμενα πρωτόκολλα δικτύωσης. Δημιουργεί ένα δικτυακό πλέγμα (mesh networking), στο οποίο τα τηλεγραφήματα αναμεταδίδονται από όλες τις γειτονικές συσκευές του μέχρι να φτάσουν στην τελική, στην οποία απευθύνονται. Το ZigBee έχει σχεδιαστεί με γνώμονα την ανεκτικότητα σε παρεμβολές RF, καθιστώντας το ένα από τα καλύτερα πρότυπα επικοινωνίας για έξυπνα σπίτια, που συνήθως βρίθουν τεχνολογίας.

Ασφάλεια λειτουργίας και επικοινωνίας των συστημάτων Control4

Η Control4 έχει στη φαρέτρα της προϊόντα που καλύπτουν όλες τις ανάγκες των πελάτων της και για όλες τις μορφές επικοινωνίας: ασύρματο δίκτυο WiFi, ενσύρματες συνδέσεις Ethernet (802.3), τη δύναμη του Bluetooth ή του AirPlay ακόμη και του DLNA. Τα επιλεγμένα συστήματα της διαθέτουν συμβατότητα Z-Wave, ώστε να επικοινωνούν με προϊόντα τρίτων κατασκευαστών επιτρέποντας τον χειρισμό τους. Η χρήση του ZigBee Pro ήταν μια επαναστατική επιλογή με άριστα αποτελέσματα στα συστήματα φωτισμού της και ακολουθήθηκε από το σύνολο του ανταγωνισμού.

Με τόσους πολλούς και διαφορετικούς τρόπους σύνδεσης ήταν απαραίτητο η επικοινωνία μεταξύ των προϊόντων της να πραγματοποιείται κωδικοποιημένα και απροσπέλαστα. Όλα τα προϊόντα της Control4 διαθέτουν ένα ενδεδειγμένο chip που είναι υπεύθυνο για την αναγνώριση και απόδοση δικαιωμάτων σύνδεσης στο επιθυμητό δίκτυο. Επιπλέον το πρωτόκολλο λειτουργίας της δεν είναι «ανοικτό», αλλά πλήρως κωδικοποιημένο επιφέροντας αύξηση της ασφάλειας. Ακόμη και οι εμπειρότεροι προγραμματιστές της Control4 δεν έχουν την δυνατότητα ανάγνωσης του δικτύου, των τηλεγραφημάτων που μεταδίδονται ή της δυνατότητας προσθαφαίρεσης συσκευών χωρίς το βασικό πρόγραμμα και τα κλειδιά πρόσβασης που διαθέτει ο ιδιοκτήτης.

Basic structure and control method of LED electronic display screen

As an efficient information display tool, LED electronic display screen is widely used in advertising, transportation, sports and other fields. Its basic structure and control method are the keys to achieving efficient and clear display. The following is a detailed introduction to the main components of the LED electronic display and its control methods.

Screen structure

The screen body of the LED electronic display is the core part of displaying information, and is mainly composed of display lattice, row and column drive circuits and other auxiliary circuits. The display dot matrix is usually composed of 8×8 single-color or two-color display units, and various combinations are used to form display screens of various sizes and resolutions. For example, a 32×128 bar screen requires 64 8×8 display units arranged in a 4×16 format. What is an LED box?

Intelligent display unit

The intelligent display unit is a small system that can independently complete the display task and can display Chinese characters, lines and simple graphics. It usually contains a main control microcontroller, RS-485 communication interface, Chinese character library and display buffer, etc. Each intelligent display unit has a unique number or address to facilitate system control and data transmission. Depending on the size and needs of the display, an appropriate number of smart display units can be selected. Provide you with LED display specifications.

Main controller

The main controller is the backbone of the LED electronic display system. It also uses a single-chip microcomputer as the main control device and is equipped with a Chinese character library, a data memory with power-down protection, a real-time calendar clock, and multiple HS-485 communication interfaces. The main controller is responsible for receiving commands and display data from the computer and distributing this information to various intelligent display units while ensuring the synchronization of the displayed content. The main controller allows the LED electronic display system to work independently without relying on an external computer. Take you 5 minutes to understand the LED display control system.

Computers and application software

The computer and its application software are responsible for updating the display content as needed, changing the display mode, and realizing online dynamic display. Since the data display content of the LED display is relatively simple, the amount of data is not large, and the update frequency is not high, the data transmission between the host computer and the lower computer usually uses serial asynchronous communication. The level standard of the communication interface can be selected from RS232, RS422 or RS485 to adapt to different application environments and transmission distances.

Control method

The control methods of LED electronic display mainly include the following aspects:

Synchronous control: Communication synchronization between the main controller and the intelligent display unit ensures the consistency and accuracy of the displayed content.

Asynchronous communication: Data transmission with the computer uses serial asynchronous communication to adapt to different communication distances and environmental requirements. Knowledge about synchronous control and asynchronous control of LED display.

Display mode management: Control changes in display modes through application software, such as static display, scrolling display, flashing display, etc.

Content update: The application software on the computer is responsible for generating and updating the display content, transmitting it to the main controller through the communication interface, and then distributing it to each display unit by the main controller.

Through the above structure and control method, LED electronic display screen can achieve efficient, stable and diversified information display to meet the display needs of different occasions.
