Abstract
The utility model relates to a portable tester for a railway air conditioning unit. The portable tester for the railway air conditioning unit comprises a handheld temperature and humidity measuring probe, a pincerlike current measuring probe, a host machine and a display screen. The host machine is connected with the display screen and the host machine and the display screen are integrally assembled. The host machine is provided with a first RS232 (Recommend Standard) serial port and a second RS232 serial port. The first RS232 serial port is connected with the handheld temperature and humidity measuring probe and the second RS232 serial port is connected with the pincerlike current measuring probe. The host machine is further provided with a USB (Universal Serial Bus) interface, a charge interface, a charge indicator lamp and a power on/off button. The portable tester for the railway air conditioning unit provided by the utility model is simple in structure and convenient to use, and can be used to judge whether the air conditioning unit of a passenger train meets the performance requirements or not, so as to provide a ground for whether the unit is disassembled or not.
Description
Technical field
The utility model relates to railway air conditioning equipment, is specially the equipment that a kind of railway air conditioning unit performance detects.
Background technology
In the passenger train transportation,, cause the damage of mobile unit or performance to descend easily because car body running environment is abominable.At present in transportation by railroad, behind the certain mileage of vehicle operating, just must be to main mobile unit get off maintenance and performance test, the air-conditioning unit is exactly one of them.The performance test of air-conditioning unit does not have light instrument at present, need get off to make an experiment, and the disintegration workload is big, and the air-conditioning of superior performance is also carried out this work, both need not cause huge waste yet.
The utility model content
The technical matters that the utility model solved is to provide a kind of portable railway air conditioning unit tester, and a crew member that buys car in installments carries, can be conveniently to solve the shortcoming in the above-mentioned background technology.
The technical matters that the utility model solved adopts following technical scheme to realize:
Portable railway air conditioning unit tester; Comprise hand-held temperature and humidity measurement probe, pincerlike current measurement probe, main frame and display screen; Said main frame is connected with display screen, and is assembled into one, and main frame is provided with a RS232 serial ports and the 2nd RS232 serial ports; The one RS232 serial ports connects hand-held temperature and humidity measurement probe, and the 2nd RS232 serial ports connects pincerlike current measurement probe; Also be provided with a USB interface, a charging inlet on the said main frame, a charging indicator light and an electric power on/off machine button.
Beneficial effect: the utility model is simple in structure, and is easy to use, can judge whether the carriage air conditioner unit reaches performance requirement, for unit is will not get off to disintegrate foundation is provided.
Description of drawings
Fig. 1 is the structured flowchart of the utility model.
Fig. 2 is the main frame of the utility model and the synoptic diagram of display screen.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Like Fig. 1, shown in Figure 2; Portable railway air conditioning unit tester comprises hand-held temperature and humidity measurement probe 5, pincerlike current measurement probe 4, main frame 2 and display screen 1, and said main frame 1 is connected with display screen 2; And be assembled into one; Main frame 1 is provided with a RS232 serial ports 25 and the 2nd RS232 serial ports 26, the one RS232 serial ports 25 connect the pincerlike current measurement probe 4 of hand-held temperature and humidity measurement probe 5, the two RS232 serial ports, 26 connections.Also be provided with 23, one charging indicator lights 22 of 24, one charging inlets of a USB interface and an electric power on/off machine button 21 on the said main frame 2.
During test; Hand-held temperature and humidity measurement probe 5 is connected on the main frame 1 with pincerlike current measurement probe 4; Utilize the data of two probes to keep and transfer function, the vehicle air conditioning unit turnover wind-warm syndrome humidity and the unit current delivery that record are arrived main frame 2, main frame 2 utilizes inner data handling system deal with data; Whether the performance of judging unit reaches requirement, on display screen, shows.As want printing reports, can USB mouth 23 be connected printer 3.
More than show and described ultimate principle of the utility model and the advantage of principal character and the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the instructions that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
