As shown in Figure 1, the unidirectional monitoring system of dry-mixed mortar storing blender of the present invention follows iso standard, achieves application layer, and based on UDP host-host protocol transmission data, system comprises dry-mixed mortar storing blender end monitoring single-chip microcomputer and remote server.
Wherein, single-chip microcomputer gathers building ground dry-mixed mortar storing blender machine operation and current material state, containing GPRS hardware module in single-chip microcomputer, and is sent the information gathered to long-range remote server by this module, in order to the professional realizing dry-mixed mortar storing blender is monitored on a large scale, remote server is connected with the single-chip microcomputer of all dry-mixed mortar storing blender ends being deployed in architecture production site, form one group of unidirectional monitoring system of dry-mixed mortar storing blender, collaborative work, the information that remote server one side is gathered by each dry-mixed mortar storing blender end of Internet reception monitoring single-chip microcomputer, inquiry and Monitoring Service is provided to user on the one hand by the mode of Web service, here user comprises super keeper, higher authority, mortar supplier and tank body manufacturer etc.
The data of transmission comprise three kinds of data packet message types, material variation type of notification message, a normal operation heartbeat message type and a notice of cancellation type of message.Data packet message is made up of message header and message body, and three kinds of data packet message types all have identical message header form, resolve in remote server to facilitate to received different messages.
Referring to Fig. 2, data packet message of the present invention is made up of message header and message body.
The form of message header can be adopted in two ways, as the message header form one of Fig. 2 (a) and the message header form two of Fig. 2 (b).In concrete procotol realizes, one of any two kinds of forms can be adopted.Message header is made up of seven fields:
1. device number (EquipmentID): 32 integer 4 bytes, identifies the unique number of every platform dry-mixed mortar storing blender equipment, is distributed unitedly by super keeper, when disposing, is arranged by single-chip microcomputer;
2. phone number (GPRSNumber): with on single-chip microcomputer for phone number that the SIM card accessing GPRS network is corresponding;
3. mobile station equipment coding (IMEI): distributed by GPRS module chip production manufacturer;
4. longitude location information (ClientPosXValue) and Position Latitude information (ClientPosYValue): the longitude and the latitude value that represent dry-mixed mortar storing blender geographical location information respectively.Concrete form and implication as follows:
A) represent scope: the scope of 32 integer 4 bytes, CHINESE REGION be on the occasion of;
B) computing method: by gather after, latitude information is accurate to radix point 6 (be generally 6, if more than 6, only get first 6), then acquired value is taken advantage of 1000000.If its collection latitude information is 139.959836, then corresponding ClientPosYValue field should be filled in: 139.959836*1000000=139959836.When remote server is resolved message, adopt phase anti-inference method, be the actual acquisition value of information by this value divided by 1000000 income values;
5. sequence number (SerialID): stochastic generation 32 integers when single-chip microcomputer starts, increases 1 when often sending out a new information later, to reach after the maximal value (231-1=2147483647) of expression scope again from 0;
6. type of message (MessageType): represent pass concrete meaning and the type of message.Three kinds of type of messages, the message header field value of material variation notification message is 0, the message header field value of normal operation heartbeat message is 1, the message header field value of notice of cancellation message is 2, adopts 1 byte 8 bit representation.
