The urea water of tool remote monitoring function is produced equipment

Technical field

The utility model relates to a kind of urea water and produces equipment, and espespecially a kind of urea water of tool remote monitoring function is produced equipment.

Background technology

Urea water (being called again automobile-used urea water) normally makes an addition to selectivity media reductive system (the Selective Catalytic Reduction of diesel motor, SCR) in as media reductive agent, for example, in order to reduce the content of noxious material in the waste gas of this diesel motor discharge or gas (oxides of nitrogen), general urea water is produced equipment 1, refer to shown in Fig. 1, its inside includes a mixing apparatus 12 and heating arrangement 11 and a purifier apparatus 13 being connected with these mixing apparatus 12 pipelines respectively, this mixing apparatus 12 is normally a bucket groove, the process of its production urea water is to inject processing procedure water in the bucket groove of this mixing apparatus 12, again technical grade urea (urea) is dropped in this barrel of groove, simultaneously and by stir and heating arrangement 11 circulating-heatings to fixed temperature after obtain semi-manufacture urea water, this semi-manufacture urea water being transported to purifier apparatus 13 carries out after purifying removal impurity again, can be obtained by the outlet of purifier apparatus 13 final finished product is automobile-used urea water, wherein, this urea water is produced equipment 1 its heating arrangement 11, mixing apparatus 12, the concrete structure of purifier apparatus 13 and other necessary structures are as temperature-sensitive sticker, the parts such as rabbling mechanism or concentration analyzer, under being, in technical field, possess and conventionally know that the knowledgeable knows, in this, repeat no more, in addition, this urea water is produced equipment 1 and conventionally can be electrically connected with a control module 21 of controlling module 2, this control module 21 can be electrically connected an I/O device 22 again as touch control screen, whereby, operating personnel can learn by this I/O device 22 the production status message of this urea water production equipment 1, also can assign control command by this I/O device 22 moves as controlled the running of this heating arrangement 11 or rabbling mechanism.

Refer to shown in Fig. 1, though existing urea water production device 1 can be manufactured automobile-used urea water, but this controls the function that module 2 does not have wireless operated or can control in far-end, therefore only operation at the scene of operator, therefore each urea water is produced equipment 1, all must configure enough operating manpowers, cause the raising of human cost, in addition, the production message of machinery and equipment also cannot be concentrated to instantaneity and converges whole or collect, cause managerial personnel to produce the overall production capacity of equipment 1 to each urea water and make elasticity and macroscopical regulation and control, again when machinery and equipment has abnormal or fault, maintenance personal also cannot detect and easy fault eliminating operation from far-end immediately, average time for repair of breakdowns (the Mean Time to Repair that causes board, MTTR) improve, and then cause board produce with maintenance management on puzzlement, be with, how for above-mentioned disappearance, to be improved, be the technical difficulties place that the present utility model people institute wish solves.

Summary of the invention

Because existing urea water production device, because not possessing remote monitoring function, cause operating manpower cost to increase and production maintenance management inconvenience, so the purpose of this utility model is to develop and is a kind ofly convenient to carry out from far-end the urea water that production message supervises, controls and keep in repair and produce equipment.

For reaching the above object, the utility model provides a kind of urea water of tool remote monitoring function to produce equipment, and it comprises: a urea water is produced equipment; A programmable controller, this programmable controller has an IO interface, and this programmable controller is electrically connected by its IO interface and urea water production equipment, and this programmable controller is provided with a communication interface again; A near-end main control system, this near-end main control system is to be connected with the communication interface of this programmable controller by signal line; A far-end main control system, this far-end main control system is by Internet, to be connected transmission message or control command with this near-end main control system.

The beneficial effects of the utility model are: by this programmable controller, be connected respectively with urea water production equipment and near-end main control system, and this far-end main control system is connected by Internet with near-end main control system, therefore operating personnel can supervise and control production message and the action that urea water is produced equipment in far-end, and can significantly save operating manpower demand, simultaneously, the utility model also can carry out from far-end the maintenance of production management and machinery and equipment, and then makes the utility model can reach the effect that reduces human cost and improve production management and keep in repair convenience.
