Main purpose of the present invention is to solve the problem and deficiency, provides a kind of repair time short, is easy to two, same compartment air-conditioner set and looks into out of order rail vehicle air conditioner group repair method.
For achieving the above object, technical scheme of the present invention is:
A kind of rail vehicle air conditioner group repair method, comprise in compartment two outwards transmission operating datas air-conditioner set and for receiving operating data and the apparatus for examination and repair of display, described apparatus for examination and repair is connected by communication interface with two described air-conditioner set, parsing operation data after apparatus for examination and repair receives operating data also show, by contrasting the operating data of two described air-conditioner set, judge wherein whether a described air-conditioner set has fault.
Further, in described air-conditioner set, be provided with air-conditioning control panel, in described air-conditioning control panel, be provided with diagnostic module.
Further, when overhauling, the operating data of the compressor of described air-conditioner set is diagnosed by described diagnostic module, shows in described apparatus for examination and repair if any its transmitting fault information of fault.
Further, when overhauling, the Frequency Converter Control data of described air-conditioner set are diagnosed by described diagnostic module, show in described apparatus for examination and repair if any its transmitting fault information of fault.
Further, the data that the temperature sensor of described air-conditioner set detects when overhauling are transferred in described apparatus for examination and repair and show, the data detected by temperature sensor and normal operation of air conditioner data compare, and judge temperature sensor and system cloud gray model whether fault.
Further, determine fault in maintenance after, by described apparatus for examination and repair, each parts in described air-conditioner set are controlled separately.
Further, in described air-conditioner set, be provided with memory module, the historical data of air-conditioner set when vehicle operating is stored in described memory module, is downloaded by described apparatus for examination and repair when overhauling.
Further, described apparatus for examination and repair is PC, is provided with data monitoring program in PC.
To sum up content, a kind of rail vehicle air conditioner group repair method of the present invention, by the contrast of two air-conditioner set data, be easy to judge whether have an air-conditioner set to break down in two air-conditioner set in same compartment, eliminate two Properties of Air-conditioning Unit and mutually disturb covering, not easily find a wherein problem broken down.By the operating data state of apparatus for examination and repair display air-conditioner set, can open-and-shut discovery air-condition faults, within shortening repair time to 10 minute greatly.Apparatus for examination and repair is downloaded historical data, can have the fault occurred in car operation by data analysis, is easy to reappear fault.
Accompanying drawing explanation
Fig. 1 is schematic flow sheet of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the present invention is described in further detail:
A kind of rail vehicle air conditioner group repair method, is mainly used in the Quick overhaul to air-conditioner set after guideway vehicle Hui Ku.Mainly be included in two air-conditioner set in compartment, this air-conditioner set outwards can transmit operating data, an apparatus for examination and repair, this apparatus for examination and repair can receive the operating data of air-conditioner set and show, in the present embodiment, apparatus for examination and repair is PC, installation data watchdog routine in PC.PC is connected by communication interface with two air-conditioner set, in maintenance process, air-conditioner set constantly transfers data in PC, and resolved by data monitoring program and show, by contrasting the operating data of two air-conditioner set, judge wherein air-conditioner set whether poor-performing or break down.By the contrast of two air-conditioner set data, be easy to judge whether to have in two air-conditioner set in same compartment Properties of Air-conditioning Unit poor or break down, eliminate two Properties of Air-conditioning Unit and mutually disturb covering, not easily find a wherein problem broken down.
Be provided with air-conditioning control panel in air-conditioner set in the present embodiment, air-conditioning control panel is provided with diagnostic module, diagnostic module is used for compressor and Frequency Converter Control etc. and diagnoses.When overhauling, the compressor operating data of air-conditioner set are diagnosed by diagnostic module, and if any fault, its failure message comprises malfunction coding etc. and is all transferred in the monitoring software of PC and shows, can open-and-shut discovery compressor fault problem.Frequency Converter Control data are diagnosed by diagnostic module equally, and if any fault, its failure message shows on the monitoring software being transferred to PC.
The data that each temperature sensor of air-conditioner set detects, comprise the temperature value etc. of the ambient temperature inside and outside compartment, compressor exhaust temperature, evaporator-condenser, all be transferred on the monitoring software of PC, routine data contrast during by normally running with air-conditioner set, can judge each temperature sensor whether fault.
Determine fault in maintenance after, also control separately by each parts of apparatus for examination and repair to air-conditioner set.
Also memory module is provided with in air-conditioner set in the present embodiment, the historical data of air-conditioner set in track car operation process stores in a storage module, downloaded by the monitoring software in PC when overhauling, by analyzing the historical data downloaded, diagnose the fault occurred in car operation, be easy to reappear fault.
This repair method, can the fault of open-and-shut discovery air-conditioner set by the operating data state of apparatus for examination and repair display air-conditioner set, shortens the repair time greatly, and the greatly less work capacity of maintenance, within whole maintenance process can foreshorten to 10 minutes.
As shown in Figure 1, the main maintenance process of this rail vehicle air conditioner group repair method is: PC is accessed air-conditioner set by communication interface by service personnel, the monitoring software of the inherent PC of 5 minutes demonstrates the Various types of data state of two air-conditioner set, as compressor fault code, compartment internal and external temperature, evaporator condensation actuator temperature etc.Service personnel contrasts the data such as two air-conditioner set evaporators, condenser temperature value, judges whether the poor-performing of an air-conditioner set or breaks down, and finds in advance to lack the potential problemes such as fluorine.Service personnel carries out trouble diagnosing by observing all kinds of air-conditioner set status data, especially compressor behavior, whether whether Frequency Converter Control communication data sends correct, each temperature sensor normally work.Air-conditioner set historical data in guideway vehicle operation is downloaded by monitoring software by service personnel, by analysis of history data, and the fault that diagnosis air-conditioner set occurs in car operation.
As mentioned above, plan content given by reference to the accompanying drawings, can derive similar technical scheme.In every case be the content not departing from technical solution of the present invention, any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
