Part producer also provides some long distance control systems at present, monitoring central air-conditioning that can be real-time, but certain customers, tighter to the network management and control as army, military base etc., the internet can not be provided to the outside, such user just can't monitor, a lot of lawless persons utilize the central-remote monitoring system to enter in user's the LAN in addition, carry out some illegal operations, reveal some capsule information of user, cause irredeemable loss.
Summary of the invention
At the deficiency that prior art exists, the purpose of this invention is to provide a kind of safe and reliable, can in time prevent or the computer based central air-conditioning remote monitoring and warning system of handling failure.
To achieve these goals, the technical solution used in the present invention is:
A kind of computer based central air-conditioning remote monitoring and warning system, comprise central air-conditioning unit, information acquisition unit and control module, the signal that described information acquisition unit is gathered the central air-conditioning unit passes to control module, described control module is connected with the networking unit, described signal passes to long-range computer by the networking unit after control module is handled, behind the signal that described Computer Analysis control module is handled, judge whether the central air-conditioning unit exists fault, if any fault, then fault message is sent on the terminal device of computer installation.
Preferably, described computer installation has dedicated firewall, receives only the signal that networking unit transmission comes.
Preferably, described networking unit comprises the networking converter, and the MAC Address of described networking converter is bundled on user's the LAN.
Preferably, described signal gathering unit comprises temperature sensor, pressure sensor and flow sensor.Described signal gathering unit is distributed in each circulatory system of central air-conditioning unit.
Preferably, described control module comprises Programmable Logic Controller and the display screen that is connected with Programmable Logic Controller respectively, communication unit and fault alarm.
Preferably, described terminal device is mobile phone, and described mobile phone is by the long-range computer of internet access.
Beneficial effect of the present invention:
(1) advanced design of the present invention, automatically the signal of control module is analyzed, accurately judge whether the parameter setting is reasonable, the precognition potential faults, thereby fault is eliminated in bud, after adopting remote computer to monitor in addition, engineer and air conditioning managing personnel can be anywhere, pass through the monitoring website of computer any time, check the ruuning situation of air-conditioning, even after breaking down in addition, the engineer also can in time be known fault message by modes such as SMSs, in order to prepare to respond in advance, responsiveness and maintenance efficiency and speed have been improved.
(2) computer installation of the present invention dedicated firewall, receive only the information of networking converter, and can not receive other relevant information of user, and the long-range computer network of calling party initiatively not, so just can guarantee the security of user network.
(3) MAC Address of networking converter of the present invention is bundled on user's the network, and miscellaneous equipment then can not utilize the network of networking converter to conduct interviews like this, improves its security.
(4) mobile phone of the present invention can be by the long-range computer of internet access, thereby control central air-conditioning unit is convenient and swift.
Description of drawings
Fig. 1 is structural representation of the present invention.
Number in the figure explanation: 1, central air-conditioning unit; 2, information acquisition unit; 3, Programmable Logic Controller; 4, signal adapter; 5, networking converter; 6, computer; 7, mobile phone.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
Consult Fig. 1, a kind of specific embodiment of the present invention is provided, a kind of computer based central air-conditioning remote monitoring and warning system, comprise central air-conditioning unit 1, information acquisition unit 2 and control module, the signal that information acquisition unit 2 is gathered central air-conditioning unit 1 passes to the Programmable Logic Controller 3 of control module, Programmable Logic Controller 3 is connected with the signal adapter 4 of networking unit, signal carries out Data Format Transform by signal adapter 4, give long-range computer 6 by the network delivery of networking converter 5 then, behind the signal that computer 6 analysis controlling units are handled, judge whether central air-conditioning unit 1 exists fault, if any fault, then fault message is sent on the terminal device of computer 6 settings, terminal device comprises mobile phone 7, mailbox etc.Computer 6 is provided with dedicated firewall, receives only the signal that networking unit transmission comes.
The networking unit comprises networking converter 5, and the MAC Address of networking converter 5 is bundled on user's the LAN.Signal gathering unit 2 comprises temperature sensor, pressure sensor and flow sensor, is distributed in each circulatory system of central air-conditioning unit 1.Display screen, communication unit and fault alarm (not drawing among Fig. 1) that control module comprises Programmable Logic Controller 3 and is connected with Programmable Logic Controller 3 respectively
Signal gathering unit 2 is gathered the temperature on central air-conditioning unit 1 each circulatory system, pressure and flow signal, pass to then on the Programmable Logic Controller 3 of control module, Programmable Logic Controller 3 sends various signals to signal adapter 4 by cable, signal adapter 4 becomes the RS485 form with the RS232 format conversion of signal, and then send to the networking converter 5, networking converter 5 passes to long-range computer 6 by the user network of its connection with various signals, 5 signals that send unit of networking converter, do not relate to network user's information, so just do not exist the network information of user side to divulge a secret.After 6 pairs of signals of computer carry out analyzing and processing, if having unusual or potential faults, then corresponding signal is sent in relevant work personnel's the mobile phone 7 or mailbox, so that the staff in time takes measures.In addition, also can be by the long-range computer 6 of internet access after mobile phone 7 processes are authorized, computer 6 is controlled, transmitted control signal to the Programmable Logic Controller 3 of central air-conditioning unit 1 by computer 6, control signal comprises start, shutdown, adjustment and other control.
