依據混凝土全自動攪拌車數據收集終端的實踐需求,再考慮到模塊的通用性確認終端技術指標如下。
According to the practical requirements of the data collection terminal of the automatic concrete mixer, and considering the universality of the module, the technical indicators of the terminal are confirmed as follows.
(1)模塊作業電壓:本終端的作業電壓來源于車載電瓶,一般為12V或許24V,模塊電壓應小于電源電壓;
(1) Module operation voltage: the operation voltage of the terminal comes from the vehicle battery, generally 12V or 24V, and the module voltage should be less than the power supply voltage;
(2)通訊方法:可采用無線網絡和短信息方法通訊;
(2) Communication method: wireless network and SMS can be used for communication;

(3)終端在線率:為了保證終端與監控中 心數據溝通的實時性,終端應堅持高在線率;
(3) Terminal online rate: in order to ensure the real-time data communication between the terminal and the monitoring center, the terminal should adhere to the high online rate;
(4)丟包率:丟包率是指測驗中,所丟掉數據包數量占所發送數據包的比率,為了下降數據丟包率,在規劃中能夠考慮,發作無線傳輸模塊不能銜接網絡,導致終端不能登錄體系的狀況時,待無線傳輸模塊脫離盲區后,將數據補傳至服務器;
(4) Packet loss rate: packet loss rate refers to the ratio of the number of lost packets to the number of sent packets in the test. In order to reduce the packet loss rate, it can be considered in the planning that when the wireless transmission module cannot connect to the network, resulting in the terminal unable to log in to the system, the data will be sent to the server after the wireless transmission module is out of the blind area;
(5)定位精確度:混凝土全自動攪拌車車輛監控調度體系的電子地圖精度數量級是米,我國二級路途的規范寬度為30~60m,假如要對混凝土全自動攪拌車車輛進行精 確的監控,定位精度需控制在30m以內,不然,當兩條路途的間隔過近時,就或許呈現定位過錯,即正在某條公路上行進的車輛被定為在路途外或其它路途上;
(5) Positioning accuracy: the accuracy of the electronic map of the automatic concrete mixer vehicle monitoring and dispatching system is in the order of meters. The standard width of the secondary road in China is 30 ~ 60m. If the automatic concrete mixer vehicle is to be monitored accurately, the positioning accuracy should be controlled within 30m. Otherwise, when the distance between the two roads is too close, the positioning fault may appear, That is to say, the vehicles moving on a certain road are classified as on the road or on other roads;

(6)備電池:當發作主電源被人為或意外堵截時,備用電池作為終端電源;
(6) Backup battery: when the main power supply is blocked artificially or accidentally, the backup battery is used as the terminal power supply;
(7)作業溫度規模:終端作業于室外,往復于攪拌站和工地之間,環境較惡劣,在溫度規模-20℃~70℃之間,終端應能正常作業;
(7) Operating temperature scale: the terminal operates outdoors and reciprocates between the mixing station and the construction site. The environment is harsh. The terminal should be able to operate normally when the temperature scale is between - 20 ℃ and 70 ℃;

(8)終端尺度:終端被安裝在混凝土全自動攪拌車內,尺度不宜過大,所以要盡或許的減小車載終端的體積;
(8) Terminal scale: the terminal is installed in the automatic concrete mixer, so the scale should not be too large, so the volume of the vehicle terminal should be reduced as much as possible;
(9)終端分量和功耗:為了契合現代車載產品的發展趨勢,終端應當被規劃成分量小功耗低
(9) Terminal components and power consumption: in order to fit the development trend of modern vehicle products, terminals should be planned with small components and low power consumption
