Existing this cover production system, every equipment all is relatively independent, though automaticity of today is higher, every equipment can carry out certain intelligent management and control to self, but individual device is contact not, still need special operating personnel to manage monitoring separately, with the situation that in time notes abnormalities.Like this, the management and monitoring efficiency ratio of whole production system is lower, and the personnel that need are also more, the operating cost height.On the other hand, production data statistics and data sink are inconvenient always, must fetch data respectively by every equipment, and record gathers, and link is many, makes mistakes easily.
Summary of the invention
The objective of the invention is to overcome the shortcoming of the described existing paster production system of background technology, invent a kind of paster production control manufacturing execution system that utilizes radio sensing network to carry out data acquisition, network management.
The paster production control manufacturing execution system of this data acquisition, in the production place, arrange to have SMT chip mounter, printing machine, tin cream thicknessmeter, crest welder, optical tester and X-ray tester, form streamline and be arranged in order, each component devices has the operation running parameter of computer control and collection itself separately.It is characterized in that: also be provided with wireless environmental data collecting node in the production place, be arranged in each position of production environment, the work environment data of monitoring whole production system mainly is exactly a temperature and humidity; On the control computer of each component devices, connect the radio sensing network forward node; And server is set, server can receive the wireless signal of above-mentioned environmental data collecting node and wireless forward node, and cloud computing system also is installed on the server, and each building block is controlled.
Preferably: the radio sensing network forward node on each component devices connects by the serial ports of the control computer of equipment, obtains the parameter that equipment itself is gathered.
Further preferred: as the note distribution apparatus to be installed, on the server such as short message transceiver.Server after the operational parameter data analyzing and processing that gathers, sends note as required.The content of note can be that alarm also can be that data are informed.
Like this, the present invention utilizes the radio sensing network technology, and environment and each component devices of production system are formed a radio sensing network, and device data gathers in real time, automatically analyze, control in real time only need just can be understood the ruuning situation of whole production system to the operation of server, and finishes technology adjustment and control to each component devices by the MES system software, improved production efficiency greatly, quantitative requirement to operating personnel is also low, reduces weariness working, improves the quality of production.

Embodiment
As shown in Figure 1, a concrete example application of the present invention is described.
In the system of the present invention, the SMT chip mounter is the chip mounter of the sa 6M620 of PANASONIC, this equipment itself contains computing machine, move by computer control, and the operational factor that computing machine is directly gathered this equipment is stored in the computing machine, these parameters are: material rate, error message, material usage quantity and other technological parameters are counted, lost to paster, and on the force pipe of chip mounter pressure transducer is arranged, and pressure data is also obtained by computing machine; Contain serial ports on the computing machine, connect the node of a radio sensing network on serial ports, present embodiment preferably adopts the wireless sensing node of Zigbee agreement.Use the advantage that mainly contains the following aspects of the wireless-transmission network of ZigBee technique construction: 1. low-power consumption is under the low power consumption standby mode, and No. 5 dry cells of 2 joints can be supported 1 node work 6-24 month, even longer.This is the outstanding advantage of ZigBee.Compare, bluetooth can only be worked and can be worked a few hours several weeks, WiFi.
2. low-cost by significantly simplify agreement (less than bluetooth 1/10), reduced requirement, by forecast analysis to communication controler, 8 8-digit microcontrollers measuring and calculating with 8051, Full Featured host node needs the 32KB code, and the subfunction node is few to the 4KB code, and ZigBee exempts from the agreement patent royalty.
3. low rate ZigBee is operated in the communication speed of 250kbps, satisfies the application demand of lower rate transmissions data.
The short-distance transmission scope one between 10～100m, after increasing the RF emissive power, also rise to 1～3km.This refers to the distance between adjacent node.If by the relay of route and inter-node communication, transmission range can be farther.
5. the response speed of prolonging ZigBee in short-term is very fast, and one changes duty over to from sleep and only needs 15ms, and the node connection enters network only needs 30ms, has further saved electric energy.Compare, bluetooth needs 3～10s, WiFi to need 3s.
6. high power capacity ZigBee can adopt starlike, sheet and mesh network topology, and by a host node management plurality of sub node, maximum host nodes can be managed 254 child nodes; Host node also can be formed the big net of 65000 nodes at most by the last layer network node control simultaneously.
