How uniapp application realizes smart parking and parking lot management
With the increasing number of vehicles, parking has become an important and thorny issue in urban life. In order to solve the parking problem, it has become a trend to use intelligent technology to manage parking lots. The uniapp framework provides a cross-platform development method that can easily develop applications that support smart parking and parking lot management. This article will introduce how to use uniapp to implement smart parking and parking lot management, and provide corresponding code examples.
1. Smart parking
Smart parking refers to the use of technical means to realize functions such as automatic parking space search and automatic navigation in the parking lot, which greatly improves the efficiency and convenience of parking. The key to realizing smart parking in uniapp is to obtain parking space information, determine whether the parking space is available, and implement automatic navigation functions.
// 在页面加载时,发送http请求获取车位信息 mounted() { uni.request({ url: 'http://localhost:8080/getParkingLot', method: 'GET', success: (res) => { this.parkingLot = res.data }, fail: (err) => { console.log(err) } }) }
<!-- 使用v-for指令遍历车位信息列表 --> <view v-for="(lot, index) in parkingLot" :key="index"> <!-- 根据车位的状态设置相应的样式 --> <view :class="{ 'parking-lot': true, 'available': lot.isAvailable }">{{ lot.lotNumber }}</view> </view>
// 用户选择目的地后,发送http请求获取导航路线 navigateTo(destination) { uni.request({ url: 'http://localhost:8080/getNavigation', method: 'GET', data: { destination: destination }, success: (res) => { const navigation = res.data // 跳转到导航页面,并将导航信息传递给导航页面 uni.navigateTo({ url: '/pages/navigation/navigation?navigation=' + JSON.stringify(navigation) }) }, fail: (err) => { console.log(err) } }) }
2. Parking Lot Management
Parking lot management refers to the management and statistics of parking spaces, orders and other information in the parking lot to improve the parking lot utilization and management efficiency. The key to realizing parking lot management in uniapp lies in the data addition, deletion, modification, and data statistics functions.
// 添加车位 addParkingLot(lotNumber) { uni.request({ url: 'http://localhost:8080/addParkingLot', method: 'POST', data: { lotNumber: lotNumber }, success: (res) => { console.log(res.data) }, fail: (err) => { console.log(err) } }) } // 删除车位 deleteParkingLot(lotNumber) { uni.request({ url: 'http://localhost:8080/deleteParkingLot', method: 'DELETE', data: { lotNumber: lotNumber }, success: (res) => { console.log(res.data) }, fail: (err) => { console.log(err) } }) } // 修改车位 updateParkingLot(lotNumber, isAvailable) { uni.request({ url: 'http://localhost:8080/updateParkingLot', method: 'PUT', data: { lotNumber: lotNumber, isAvailable: isAvailable }, success: (res) => { console.log(res.data) }, fail: (err) => { console.log(err) } }) } // 查询车位 searchParkingLot(lotNumber) { uni.request({ url: 'http://localhost:8080/searchParkingLot', method: 'GET', data: { lotNumber: lotNumber }, success: (res) => { console.log(res.data) }, fail: (err) => { console.log(err) } }) }
// 统计停车场的使用情况 getParkingStatistics() { uni.request({ url: 'http://localhost:8080/getParkingStatistics', method: 'GET', success: (res) => { console.log(res.data) }, fail: (err) => { console.log(err) } }) } // 统计停车场的收入 getIncomeStatistics() { uni.request({ url: 'http://localhost:8080/getIncomeStatistics', method: 'GET', success: (res) => { console.log(res.data) }, fail: (err) => { console.log(err) } }) }
Through the above code examples, we can see that it is very convenient to implement intelligent parking and parking lot management in uniapp. By obtaining parking space information, judging parking space availability and realizing automatic navigation, users can quickly find parking spaces; and by adding, deleting, modifying, checking and statistics of parking spaces, orders and other data, parking lot managers can manage parking lots efficiently. The implementation of these functions not only improves the efficiency and convenience of parking, but also improves the management level of the parking lot.
