# Sixth Lichuang Electric Competition# Warehouse security control system

* 1. Introduction to project functions

   The starting point of this system is the intelligent safety management of the warehouse. Four relays are used instead of machine operation to simulate the warehouse environment;

    This system mainly consists of 2 parts:

 1: It is a lower computer with main control, temperature and humidity, smoke sensor, access control, SIM, relay, buzzer, LED, etc.

2: The host computer developed by QT has login protection function, temperature and humidity, smoke historical data storage and current data display, temperature and humidity threshold setting, machine remote opening and closing function, alarm release function, and access control data collection function;

It has the following functions overall:

1. Collect the temperature, humidity, smoke and other parameters of the warehouse in real time and transmit them to the host computer

2. After the data is collected by the host computer, it is displayed on the interface and generates a curve graph for more direct viewing.

3. The upper computer can set the alarm threshold

4. If the temperature, humidity, and smoke reach the alarm threshold, the buzzer will sound, the warning light will flash, a warning will be displayed, and information will be sent to the mobile phone through the SIM module, and the machine will automatically shut down.

5. There is a system login interface. Only people with administrative rights can log in to this system.

6. Remote control machine functions (replaced by relays)

7. Access control data collection can display a series of data such as the person who opened the access control, opening time, position and contact information. If an accident occurs in the warehouse, the specific person can be reached.

* 3. Open source agreement

CC-BY-NC-SA 3.0

Commercial use is prohibited, learning is encouraged;

Note: Altruism means self-interest, please read the following content carefully.

1. Embrace open source and give projects unlimited value. It is recommended that more than 80% of the core functions of the project be open source;
2. If a certain part of the function is irreplaceable and the project cannot solve the corresponding problem after deletion, then the function implemented by this part is the core function of the project; for example, if an electronic load is designed and a host computer software is designed to monitor power changes, the electronic The load is the core function, and the host computer software is the auxiliary function; for example, an isolated 485 module is used in the electronic load to communicate with the host computer, then the communication function implemented by this 485 module is an auxiliary function;
3. Projects should choose an open source agreement that suits them . If the project references other open source projects, the source should be indicated and follow the original author's open source agreement. It is recommended that original projects use the GPL3.0 open source agreement;
4. Functions implemented by directly quoting the original circuits or original codes of open source projects cannot be used as the core functions of one's own projects, and functions directly implemented using common modules on the market cannot be used as core functions of one's own projects.

* 4. Hardware part

The main control uses STM32F103VET6 as the main control, with peripherals composed of temperature and humidity, smoke sensor, access control, SIM, relay, buzzer, LED, etc.
