Cold chain logistics management and temperature monitoring functions of Java warehouse management system

The cold chain logistics management and temperature monitoring functions of the Java warehouse management system require specific code examples

With the continuous development of the logistics industry, cold chain logistics has become increasingly important in food, It plays an important role in pharmaceutical and other industries. In order to ensure the safety and quality of goods during the logistics process, the warehouse management system needs to have the functions of cold chain logistics management and temperature monitoring.

Cold chain logistics management mainly includes cargo tracking and positioning, temperature and humidity monitoring and alarms, transportation route planning, etc. Temperature monitoring is one of the most important links in cold chain logistics. By monitoring and recording the temperature changes of goods in real time, abnormalities can be discovered in time and corresponding measures can be taken to ensure the quality of the goods.

Below, we will use a simple sample code to demonstrate the implementation of the cold chain logistics management and temperature monitoring functions of the Java warehouse management system.

First, we need to create a temperature sensor class named TemperatureSensor to simulate temperature collection. The sample code is as follows:

public class TemperatureSensor {

    public double getTemperature() {
        // 模拟温度采集
        Random random = new Random();
        double temperature = random.nextDouble() * 10 + 20; // 生成20~30之间的随机温度
        return temperature;
    }
    
}

Next, we create a warehouse class named Warehouse for managing goods and monitoring temperature. The sample code is as follows:

public class Warehouse {

    private List<Goods> goodsList;
    private TemperatureSensor temperatureSensor;

    public Warehouse() {
        goodsList = new ArrayList<>();
        temperatureSensor = new TemperatureSensor();
    }

    public void addGoods(Goods goods) {
        goodsList.add(goods);
    }

    public void removeGoods(Goods goods) {
        goodsList.remove(goods);
    }

    public void checkTemperature() {
        double temperature = temperatureSensor.getTemperature();
        for (Goods goods : goodsList) {
            if (goods.getTemperatureRange().contains(temperature)) {
                System.out.println("货物：" + goods.getName() + " 温度正常");
            } else {
                System.out.println("货物：" + goods.getName() + " 温度异常，当前温度为：" + temperature);
            }
        }
    }

}

Next, we create a goods class named Goods to manage the information and temperature range of the goods. The sample code is as follows:

public class Goods {

    private String name;
    private Range<Double> temperatureRange;

    public Goods(String name, Range<Double> temperatureRange) {
        this.name = name;
        this.temperatureRange = temperatureRange;
    }

    public String getName() {
        return name;
    }

    public Range<Double> getTemperatureRange() {
        return temperatureRange;
    }
    
}

Finally, we create a main class named Main to test the functionality of the warehouse management system. The sample code is as follows:

public class Main {

    public static void main(String[] args) {
        Warehouse warehouse = new Warehouse();
        Goods goods1 = new Goods("苹果", Range.closed(0.0, 10.0)); // 苹果的温度范围为0~10度
        Goods goods2 = new Goods("牛奶", Range.closed(2.0, 8.0)); // 牛奶的温度范围为2~8度
        warehouse.addGoods(goods1);
        warehouse.addGoods(goods2);

        for (int i = 0; i < 10; i++) {
            warehouse.checkTemperature(); // 每隔一段时间检查温度
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
}

Through the above sample code, we created a simple warehouse management system and implemented the functions of cold chain logistics management and temperature monitoring. Among them, TemperatureSensor simulates the temperature collection process of the temperature sensor, the Warehouse class manages the goods and temperature sensors, and monitors the temperature of the goods through the checkTemperature() method , Goods class manages the information and temperature range of the goods, and Main class tests the functions of the warehouse management system.

Of course, the above is just a simplified example, and actual warehouse management systems involve more functions and complexities. But through this example, you can clearly understand the basic implementation of cold chain logistics management and temperature monitoring of the Java warehouse management system.
