at present, most of transformer cooling control systems adopt PLC controllers, and the PLC controllers have the advantages that the temperature is adjusted by automatically controlling the cooling systems according to the temperature change of the oil surface of the transformer, and the cooling capacity does not need to be adjusted manually.
However, the existing PLC controller technology cannot allow a user to conveniently know the signal state in the control cabinet and the operation condition of the controller at any time and any place, and a designer must go to the site to modify the program even if the program is slightly modified.
Specifically, the prior art mainly has the following technical problems:
(1) the existing PLC controller needs a technician to debug after arriving at the site, and the technician must go to the site even if the program needs to be slightly changed during operation.
(2) The PLC controller can not conveniently check the state of signals in the control cabinet at any time and any place during operation.
(3) When the PLC controller breaks down, the operation personnel can not know whether the variables in the PLC controller are normal or not, and the designer can not remotely assist in diagnosis.
(4) The problems that the factory PLC controllers cannot be monitored in a centralized manner and compared and analyzed in a centralized manner are solved, and technical upgrading of products is not facilitated.
Therefore, as network technology develops, a new system needs to be constructed to solve the above problems.
The utility model has the following contents:
an object of the utility model is to solve the above-mentioned technical problem, provide a PLC controller remote monitering system for transformer.
In order to achieve the above purpose, the utility model adopts the following technical scheme to realize:
the remote monitoring system of the PLC controller for the transformer comprises the PLC controller, an industrial serial port line, a wireless communication module and a remote monitoring computer; wherein,
the PLC is used for adjusting the oil surface temperature of the transformer by controlling the starting and stopping of the motor, the wireless communication module is connected with the PLC through an industrial serial port line and used for accessing resources mutually, and a 3G mobile phone card is inserted into the wireless communication module or wifi is accessed into the wireless communication module; a web monitoring platform is developed on a remote monitoring computer, and the remote monitoring computer is accessed to a wireless communication module through an HTTP interface to realize centralized monitoring.
The utility model discloses further improvement lies in, the PLC controller includes CPU, opens into, opens out and the analog quantity module for the signal of participating in logical operation in the access transformer switch board, and opening of output control motor stops.
The utility model has the advantages as follows:
(1) the utility model discloses can avoid the frequent business trip of designer to modify the PLC program, reducible field service expense.
(2) When a fault occurs, the user can be remotely assisted to analyze the accident reason, the blind business trip is avoided, and the working efficiency is improved.
(3) The PLC controllers of different projects can be managed in a centralized manner, problems can be analyzed in a centralized manner, and product technology upgrading is promoted.
To sum up, compare with current PLC controller, the utility model discloses can be anytime and anywhere through the signal of web monitor platform remote monitoring in the PLC controller and the operational aspect of all variables in the controller, help user analysis problem. The PLC ladder diagram is modified by using a remote monitoring computer, and the PLC program does not need to be modified frequently.
Description of the drawings:
fig. 1 is a schematic block diagram of the present invention.
In the figure: 1. transformer, 2, motor, 3, PLC controller, 4, industry serial port line, 5, wireless communication module, 6, web monitoring platform, 7, remote monitoring computer.
The specific implementation mode is as follows:
the present invention will be further described with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the utility model provides a transformer is with PLC controller remote monitoring diagnostic system, including PLC controller 3, industry serial port line 4, wireless communication module 5, web monitoring platform 6 and remote monitoring computer 7.
PLC controller 3 stops through controlling motor 2 and adjusts transformer 1's oil level temperature, and wireless communication module 5 and PLC controller 3 pass through industry serial port line 4 and connect, and the resource is visited each other, and wireless communication module 5 has inserted 3G cell-phone card or has inserted wifi, and both are each other redundant, adopt non-transparent transmission, update the variable through consuming the flow, read all variables inside the PLC controller.
A web monitoring platform 6 is developed on a remote monitoring computer 7, the wireless communication module 5 is accessed through an HTTP interface, centralized monitoring is achieved, related signals in the PLC 3 and the running state of the PLC 3 can be checked in real time by logging in the monitoring platform on the internet through a tablet, a mobile phone or a computer as long as checking authority is obtained, and preliminary reason analysis can be carried out when a fault occurs.
The wireless communication module 5 is set with authority, different operations can be carried out under different authorities, the user has the highest authority, the user can update the password at any time, and after the user authority is obtained, the ladder program can be updated on the remote monitoring computer 7 by utilizing remote downloading software and PLC programming software.
When the PLC controller is in operation, a user can check the state of a signal in the PLC controller and the operation condition of the PLC controller at the moment through a webpage by using any terminal capable of surfing the Internet. If faults occur in operation, a user can firstly check whether input variables of the PLC controller are normal or not according to webpage monitoring, preliminarily determine the problem, and a designer can also remotely assist in troubleshooting. If the user needs to modify the program, the designer can modify the program without going to the site and the remote place.
The above-mentioned embodiment is only one of the present invention, and is not intended to limit the present invention in any form.
