We require a system for controlling access to a building. The unit would require a small touch screen. Ability to interface to some form of electric lock Able to take simple switch inputs from sensors to show things like doors closed, doors locked, PIR detector etc. PINs and respective valid time and dates would be stored in the system. When a user enters a PIN the system checks if valid for that time/date if it is a signal is sent to a lock to open it. PINs plus times and date information are downloaded through an Internet connection. If the Internet connection is lost the system works using the stored data. Unit reports by email when someone uses the unit successfully or a failed attempt. The unit could have an IP address or regularly poll to a Website to see if update is required. I mention Raspberry PI as a controller, simply because they are easily avaialble and cheap. I would entertain other controllers

Hello! Please check my reviews to know a bit about me. I'll be using TI's TM4C123 microcontroller - because it is based on ARM cortex M3 and is pretty powerful with the price comparable to the latest raspberry pi. Your project sounds interesting but it is equally tough as well

Hi, I have worked on several projects using Raspberry pi/Arduino projects. I think you want implement intelligent door locking system using centralized server managed authentication. We can do this using several models. It depends on how you want to create access and how to deploy the system. We can use pin based authentication, RFID based authentication etc. The display part comes to picture when we want to get pin/password interactively. In case of RFID or other passive authentication, display is optional. So we can discusses about this to create a design for this. Thanks!

@vitamin4ik

Hello! I'm experienced engineer, who took part in many embedded devices projects. I've designed electronics (circuit, schematic,BOM,prototype) and software. I'm also Raspberry Pi fan and delivered many projects to customers using Raspberry. I would like to use my experience to help you with this project. I understand the scope but need your additional requirements list. I do have Raspberry. But what about other elements/devices? Should I purchase them or you can supply? I have done similar task before on other controller. I can offer previous version of solution or update it and deliver it for Raspberry Pi. What do you prefer? I'm available online since 8AM your local time. Chat with me, please! Looking forward to hear from you soon Best regards, Vitaliy

you sit are in luck because I made something similar. a system to control my computer,lights and change my a.c. according to temp. the best way that I think to approach this is to use a web based control system like I did and run a webserver in the pi to control it for better compatibility.

Hi I don’t have the Touch Screen for the raspberry pi, but I think I can do it with that in my hand. The way I’m imagine the system is using the RPi in kiosk mode, at the system start it will open a web browser that will have the interface. The web browser will access to a local page in automatic way. The web page will be done in html and will be served by the bottle framework in python. Python+Bottle will manage all the system. The local data will be stored in a sqlite3 encrypted database, because any one with access to the system will be able to retrieve all the data stored in the device. Also we cannot store the decryption key in the Raspberry Pi, the system will ask for one when the system first start, then there will be a connection at that time, later it can lose connection without problem.

Hi, Here is my proposal for the project. RPi is indeed a good choice. I suggest a Qt based application for the user interface part as well as communication with the RPi's GPIO. The opening of the door's lock, requires some external circuitry, e.g. a TTL signal out of RPi's GPIO can be interfaced with a high voltage circuitry that can activate a relay/solenoid to open doors. It is not clear that the extra circuitry is part of your project or not, so my bid is only considering the software part. I can of course design a simple test circuitry to show you it works. For the software, I can compile a minimal OS based on arm-linux so as soon as the device boots up, the screen will show the user interface. The most important question is the security, I suggest a local network, such systems should never be connected to internet! I am available on skype for more details if you choose me. Regards, Saeid.

Experience with Raspberry PI, hardware and sensor interfacing. This is a perfect project. Will need more details on the lock system and exact file format you wish to update. Ability to also log to database/online spreadsheet for easier data review.

I have developed this type of project before for parking garages. I am very experienced with this and know exactly how to set up the raspberry pi, display and set up the web communication.
