[0020] The cold chain logistics management system of the embodiment of the present invention will be described below with reference to the accompanying drawings.
[0021] figure 1 Shown is the overall structure diagram of the cold chain logistics management system of the present invention.
[0022] The cold chain logistics management system is mainly composed of a monitoring center system 1 and a vehicle-mounted intelligent terminal 2.
[0023] The monitoring center system 1 and the vehicle-mounted intelligent terminal 2 are connected with the Internet through a GPRS network.
[0024] The architecture of the monitoring center system 1 is based on the B/S application mode (Browser/Server). The monitoring center system 1 is equipped with a server, which is connected to the client through the Internet or other communication networks. The client is set at the system user, and the system user may be a manufacturer, a logistics company, a seller, a warehouse, or other related users of the item. The monitoring center system 1 can be installed in any one of the manufacturer, seller, warehouse, or logistics enterprise of the article according to the purpose. Preferably, system users and vehicle drivers can carry mobile phones to receive business information sent by the monitoring center system 1.
[0025] The vehicle-mounted intelligent terminal 2 transmits the collected vehicle driving information (including satellite positioning information, vehicle status information, etc.) to the monitoring center system 1, and the server provides the system user through background processing. The system user issues instructions through the client's IE browser, and sends them to the vehicle-mounted intelligent terminal 2 through the GPRS network to achieve task dispatch, dispatch and vehicle management.
[0026] Such as figure 2 As shown, the vehicle-mounted intelligent terminal 2 is composed of a host 21 and a vehicle-mounted data collection module 22.
[0027] The host 21 includes a GPS positioning module 211, a GSM module 212, a storage module 213, an alarm module 214, and a control module 215.
[0028] The host 21 has a unique terminal number, and each terminal number in the system uniquely corresponds to a vehicle-mounted intelligent terminal 2 installed on the vehicle.
[0029] The vehicle-mounted data collection module 22 includes multiple external devices, which are connected to the control module 215 in the host 21 through respective interfaces, and are used to collect vehicle working status information. The vehicle working state information includes temperature information, cabin switch information, and cabin image information.
[0030] The external devices include a temperature sensor 221, a door sensor 222, a camera 223, and a scheduling display screen 224.
[0031] The temperature sensor 221 can be installed at different positions inside the vehicle compartment according to the user's needs to detect the temperature, and input the temperature data into the host 21. The host 21 compares and judges according to the alarm temperature value in the storage module 213. When the temperature is abnormal, the alarm module 214 sends out a sound and light alarm. At the same time, the control module 215 sends an alarm signal to the monitoring center system 1 through the GPRS network, and the monitoring center system 1 sends Audible alarm.
[0032] The door magnetic sensor 222 is used to sense the opening and closing of the compartment, and trigger the camera 223 to take a photo whenever it is opened or closed. When the car door is opened illegally, the alarm module 214 sends out an audible and visual alarm. At the same time, the control module 215 sends an alarm signal to the monitoring center system 1 through the GPRS network, and the monitoring center system 1 sends out an audible and visual alarm.
[0033] The camera 223 can be installed above the door of the carriage to supervise the loading and unloading of the carriage and prevent fraudulent vehicle idling rate. When the door is opened or closed, or when any alarm occurs, the camera 223 will be triggered to take pictures. At the same time, the user can also take pictures manually through the host 21.
[0034] The dispatch display screen 224 is placed next to the bridge and is used for communication between system users and outside workers, and sending dispatch information and responses. The driver can see the instructions issued by the monitoring center system 1 on the dispatch display 224, so as to realize task dispatch, dispatch and vehicle management.
[0035] The GPS positioning module 211 in the host 21 receives instructions from the control module 215, collects satellite positioning information within a certain time interval, and transmits the satellite positioning information to the storage module 213 for storage; the control module 215 receives temperature signals generated by external devices, The car switch information and image information are sent to the storage module 213 for storage. The control module 215 encapsulates the satellite positioning information collected by the GPS positioning module and the vehicle working state information generated by the external device into a GPRS data packet, which is sent to the GPRS network through the GSM module 212. In a typical embodiment, 8 temperature sensors 221 are installed in the carriage, and the GPRS data packet of temperature data is:
[0036] #GMAI 00010000001 1 TS 1 00245 01152 10491 00163 10528 00667 1037300534*
[0037] That is, the temperature values collected by the corresponding eight temperature sensors 221 are:
[0038] +24.5, +115.2, -49.1, +16.3, -52.8, +66.7, -37.3, +53.4.
[0039] "00010000001" is the terminal number, which uniquely corresponds to the vehicle-mounted smart terminal 2 installed on the vehicle.
[0040] The GPS positioning module 211 collects satellite positioning information under the control of the control module and stores it in the storage module 213. The positioning information includes latitude and longitude, speed direction, and the like.
[0041] The GSM module 212 is used to send satellite positioning information and vehicle working status to the GPRS network, and receive scheduling information and control instructions of the monitoring center system 1, and forward them to the control module 212 to control the vehicle. Typically, the control command issued by the monitoring center system 1 is to set the alarm temperature of the host, and the control module 212 forwards the alarm temperature value to the storage module 213.
[0042] The alarm module 214 is used to generate an audible and visual alarm. When the temperature detected by the temperature sensor 221 is higher than the alarm temperature value, or the door magnetic sensor 222 detects an illegal opening of the car door, an alarm is generated.
[0043] The control module 215 can also detect the antenna and power reserve conditions of the vehicle-mounted intelligent terminal 2, or vehicle violations such as vehicle speeding, overloading, and crossing of boundaries, and generate an alarm to remind the driver.
[0044] The architecture of the monitoring center system 1 is based on the B/S application model (Browser/Server), which provides authorized users with a WEBGIS system for information release such as positioning and travel through the Internet or other communication networks. System users access the monitoring center system through IE browser to control and query, including business registration, business supervision, business statistics, vehicle supervision, etc.
[0045] The monitoring center system 1 includes a WEB application server 11, a WEB data server 12, a business data server 13, a map data server 14, a database server 15, a communication server 16, and a short message server 17.
[0046] The communication server 16 is used for the communication connection management between the monitoring center system 1 and the vehicle-mounted intelligent terminal 2. The GSM module 212 in the vehicle-mounted intelligent terminal 2 is connected to the GPRS network, and is connected to the Internet through the access point CMNET of the GPRS network, and is connected to the monitoring center system 1 through the TCP/IP protocol.
[0047] The map data server 14 stores GIS spatial graphic data, mainly including electronic traffic maps, which can display the spatial position, geometric characteristics and topological relationships of the road traffic network graphic elements including the shipper and the consignee, and other appendages, Such as information about government agencies, green space squares, shops and supermarkets.
[0048] Data middleware is set in the WEB data server 12 to integrate the data generated by the GPS module 211 and different external devices, and forward the vehicle driving information (including satellite positioning information, vehicle status information, etc.) collected by the vehicle-mounted intelligent terminal 2 to the WEB data server 12. Form the information for WEBGIS publishing.
[0049] The business data server 13 receives and processes business data. The business data includes order information placed by a user, vehicle temperature information, vehicle departure information, vehicle arrival information, cabin temperature information, satellite positioning information, and the like.
[0050] The database server 15 is used to store basic data and business data of the system. The business data includes temperature values collected by the vehicle-mounted intelligent terminal 2, over-temperature warning information, warning information about illegal opening of the compartment door, vehicle speeding, overloading, cross-border violations, etc. Satellite positioning information, business applications submitted by system users, and a list of completed tasks. Basic data includes user information and permissions, vehicle data, terminal data, system operation logs, etc. When the service data server 13 receives the warning information, it stores the license plate number of the warning vehicle, the corresponding order number, time and other information in the database server 15. The user can query the alarm information by the license plate number, time, and order number.
[0051] The short message server 17 can be a short message (SMS, Short Messaging Service) server or a multimedia message (MMS, Multimedia Messaging Service) server. When a system user submits a service application to the WEB application server 11, the short message server 17 is reviewed and distributed. Send the corresponding information to the user's mobile phone.
[0052] The WEB application server 11 calls the electronic traffic map stored in the map data server 14, generates a dispatch route according to the loading location and the unloading location, generates an alarm temperature value according to the temperature requirements in the task status list, and based on the license plate number in the task status list, and The terminal number corresponding to the vehicle-mounted smart terminal 2 sends the alarm temperature value to the vehicle-mounted smart terminal 2 of the corresponding vehicle and stores it in the memory 213. In communication, there are terminal numbers in the data packets, which correspond to the license plate number in the system. When selecting a vehicle to send instructions through the license plate number, the background automatically sends data to the communication address where the corresponding terminal number is located (the terminal's IP and port number for logging in to the Internet through GPRS).
[0053] The WEB application server 11 calls the short message server 17 to send short messages.
[0054] The WEB application server 11 provides a user interface. Allow users to complete business applications, vehicle status query and data statistics functions. Such as image 3 As shown, the WEB application server 11 includes a business registration module, a business supervision module, a business statistics module, a vehicle supervision module, a system management module, and a log recording module.
[0055] The business registration module provides the functions of business application, business review, person-in-charge confirmation and driver confirmation, and generates a task status list. The manufacturer user uses the business application function to submit the delivery application form, and the logistics enterprise approvers review it, and the operator assigns vehicles and drivers to generate a task status list, including order number, license plate number, model, driver, phone number, and arrival time , Loading location, unloading location and temperature requirements.
[0056] The business supervision module provides real-time supervision on the status of business documents and monitoring data in the business. The status of the business document is a key point in the cold chain logistics business process, such as "accept order", "arrival", "loading", "departure", "delivery", "unloading" and "completed". The monitoring data in the business is the real-time data monitoring of temperature fluctuations, door opening and closing, and images in the vehicle during the business operation process required by the business, that is, during the transportation process.
[0057] The business statistics module provides business data query and comprehensive statistics interface. According to the order number, business occurrence time, business receipt status, business alarm threshold, business-related vehicle, responsible person and other attribute data, filter and integrate the business reports required by the user, such as "order completion rate", "X vehicle X monthly temperature Abnormal records", "Total business volume in X years", "Receipts currently in the status of'Central China Delivery'" and so on.
[0058] The vehicle supervision module provides the functions of vehicle positioning, trajectory query and violation vehicle query. When the user selects vehicle positioning, the WEB application server 11 calls the electronic traffic map stored in the map data server 14, and displays the current positioning of the vehicle on the map according to the satellite positioning information collected by the vehicle-mounted intelligent terminal 2. When the user selects the trajectory playback function, the WEB application server calls the electronic traffic map stored in the map data server and the satellite positioning information stored in the database server 15 to form the driving trajectory of the vehicle. Violation vehicle query function provides vehicle speeding, overloading, and cross-border violation information.
[0059] The system management module provides level-level authority management for system users. User levels include administrators, operators, and browsing users. Among them, the administrator user is responsible for system supervision and maintenance, the operator user is engaged in system operation and data analysis, and browsing users accept the information and results provided by the system. The system administrator of the monitoring center sets user permissions hierarchically, and saves the setting results into a user permission table in the database server.
[0060] The log record module is used for system operation log record and provides query function. The administrator can know what user has done what operation at what time.
[0061] The operation process of the cold chain logistics management system is as follows:
[0062] Step 101: The user logs in to the WEB application server 11 through the IE browser, and the WEB application server 11 authenticates the user according to the user information stored in the database server 15. The user who has passed the authentication, such as the manufacturer, can log in to the WEB application server 11. Submit the delivery application form; the SMS server 17 sends the application information to the mobile phone of the order clerk of the logistics enterprise.
[0063] Step 102: The logistics company's order taker logs on to the WEB application server 11 and reports to the superior for approval. When the delivery application is approved or rejected, the SMS server 17 sends a short message to notify the manufacturer's ordering staff.
[0064] Step 103: After the delivery application form is approved by the logistics enterprise, the logistics enterprise operator assigns vehicles and drivers to form a task status list. The short message server 17 automatically sends short messages to notify the driver of the task and requirements for leaving the vehicle; the WEB application server 11 automatically issues instructions to the allocated vehicles according to the temperature requirements in the task status list, and sets the alarm temperature value of the vehicle intelligent terminal 2 through the GPRS network.
[0065] Step 104: After the driver leaves the vehicle, the vehicle-mounted intelligent terminal 2 starts to detect the temperature in real time, and sends it to the monitoring center system 1 via GPRS. At this point, the user can start to log in to the WEB application server 11 to locate the vehicle.
[0066] Step 105: After the vehicle arrives at the delivery point, the system automatically judges that the vehicle has arrived according to the electronic fence, and the vehicle-mounted intelligent terminal 2 records the vehicle arrival time and sends the vehicle arrival time to the monitoring center system 1.
[0067] Step 106: The compartment is cooled and after the loading is completed, the operator logs in to the WEB application server 11 to confirm that the loading is completed. Record the loading time.
[0068] Step 107: The vehicle departs from the delivery point, the system automatically judges according to the electronic fence, the vehicle-mounted intelligent terminal 2 records the vehicle departure time, and sends the vehicle departure time to the monitoring center system 1. During transportation, system users of manufacturers, logistics enterprise vehicle management, warehouses or points of sale receiving goods can log in to the WEB application server 11 to intuitively view temperature and vehicle location information. If an alarm occurs, the short message server 17 sends an alarm short message to notify the responsible person.
[0069] In step 108, the vehicle is delivered to the receiving point, the system automatically judges according to the electronic fence, the vehicle-mounted intelligent terminal 2 records the delivery time of the vehicle, and sends the delivery time of the vehicle to the monitoring center system 1.
[0070] Step 109: After the vehicle is delivered, unload the goods, log in to the WEB application server 11, and complete the "unloading confirmation" operation in the system.
[0071] In step 110, the inspector inspects the goods and logs in to the WEB application server 11 to view the historical value of the temperature and check whether the transportation temperature meets the requirements. After the inspection is passed, the system "confirms completion" and records the unloading time.
[0072] After the completion of the waybill, the vehicle returns, and the logistics company's vehicle administrator can coordinate arrangements and optimize scheduling according to the vehicle model, current location and other information, and issue other transportation tasks to the vehicle in time.
