Abstract
The invention discloses a network communication system used for a freeze dryer. The network communication system is installed on the freeze dryer and connected to Ethernet. The network communication system comprises an external control computer, recorders and an automatic feeding and discharging PLC communication module. The network communication system further comprises a network communication module and a network switch. Multiple network ports of the network switch are connected with the network communication module, the external control computer, the recorders and the automatic feeding and discharging PLC communication module through network cables respectively. Independent IP addresses are distributed to the external control module, the recorders and the automatic feeding and discharging PLC communication module respectively. The remaining network ports of the network switch serve as ports for collecting remote information. The network cables are eight-core network cables, and the network communication module is a QJ71E71-100 module. The number of communication modules can be reduced, the communication rate can be greatly increased, and the communication mode is more stable. In addition, according to the network switch, the communication interfaces are reserved for collecting the remote information.
Description
Technical field
The present invention relates to a kind of pharmaceutical purpose freeze dryer, relate to specifically a kind of network communication system of freeze dryer.
Background technology
Existing programmable logic controller (PLC) (the Programable Logic Controller that adopts Mitsubishi's brand, PLC) communication control system of freeze dryer, normally with QJ71C24 module and recorder, carry out communication, by QJ71PB93D module and Siemens System PLC or other brands (as Omron, the automatic feeding and discharging device of the module with network communication function ABB etc.) carries out communication, and carries out communication with QJ71C24 module and clo Li Sika and external control computer.The communication speed of this control system is slow, and particularly the communication between computer and PLC easily lags behind or be stuck; The price of the QJ71PB93D module adopting with the communication of automatic feeding and discharging device in addition, is very expensive.
Summary of the invention
The object of this invention is to provide a kind of network communication system for freeze dryer, can adopt Ethernet to realize the communication modes between different PLC, and can reduce communication module cost and effectively improve communication speed.
Network communication system for freeze dryer of the present invention, be arranged on freeze dryer and be connected in Ethernet, described network communication system comprises external control computer, recorder, automatic feed/discharge PLC communication module, network communication module and the network switch, and a plurality of network ports of the described network switch connect respectively described network communication module and described external control computer and described recorder and described automatic feed/discharge PLC communication module by netting twine; Described external control computer, recorder, automatic feed/discharge PLC communication module are respectively assigned with an independent IP address.
The port that the rest network port of the described network switch gathers as remote information.
Described netting twine is a kind of 8 core grid lines.
Described network communication module is to adopt QJ71E71-100 module.
Described automatic feed/discharge PLC communication module is the module with network communication function that adopts Siemens, Omron or ABB.
The quantity of described recorder is 2 or a plurality of, and a plurality of rest network interfaces of the network switch are as the standby port that increases recorder.
The invention has the beneficial effects as follows: recorder, external control computer, automatic feed/discharge communication module are connected on the network switch by netting twine respectively in Ethernet, and distribute an independent IP address to each parts; Network communication module QJ71E71-100 is connected with the network switch by netting twine, so the present invention can save communication module, greatly improve communication speed, and communication modes is more stable; In addition, the network switch is that communication interface has been reserved in teleinformatic collection.
Accompanying drawing explanation
