Abstract
An air-conditioning control equipment for rail vehicle, aiming at to solve mainly the technical matter of structural simplification. The technical proposals are that: the air-conditioning control equipment has a control panel; various control components are arranged on the control panel; a programmable micro-processing controller is also arranged on the control panel; the input end of the programmable micro-processing controller is connected with a temperature sensor, and the fan-out is connected with a contactor and a motor protection switch. The utility model is applicable for various air conditionings of rail vehicles.
Description
Technical field:
The utility model relates to a kind of air-conditioning control convenience, particularly a kind of air-conditioner controller.
Background technology:
In guideway vehicle, as light rail train etc., be equipped with the A/C of regulating temperature in each compartment, this A/C has well behaved control convenience, when train operation, different environmental changes, the passenger all can be in best comfort conditions.Described control convenience includes a control desk, control desk is provided with various assemblies, as terminal, voltage transformer, programmable logic controller (PLC), amplifier, contactless switch and protection switch etc., the functional block diagram of this control convenience as shown in Figure 4, the input end of diagram programmable logic controller (PLC) connects temperature sensor, the input analog amount of sensor is through the programmable logic controller (PLC) procedure operation, and output after amplifier amplifies, control contactor or protection switch running, realize the regulatory function of air-conditioning unit, meet setting value with temperature or other parameters in the maintenance compartment; But said structure because the output parameter of programmable logic controller (PLC) in the equipment must could be realized its controllable function after the amplification of amplifier, makes device structure complicated, and the applicability of its power supply, temperature sensor input all remain improvement.
The utility model content:
Technical problem to be solved in the utility model is to provide a kind of improved used for rail vehicle air-conditioner controller, the structure of its energy simplified apparatus, the reliability of raising equipment operation.
The technical scheme in the invention for solving the above technical problem is: the air-conditioning control convenience includes a control desk; control desk is provided with terminal; voltage transformer; contactless switch and motor protection switch; be characterized on control desk, also being provided with a microprocessor controller able to programme; the input end of microprocessor controller able to programme is connected with temperature sensor; the mouth of microprocessor controller able to programme is connected with contactless switch and motor protection switch; the analog quantity of temperature sensor is realized the regulatory function of air-conditioning unit through microprocessor controller conversion output control contactor able to programme and motor protection switch action.
The structure of the utility model mat controller direct connection temperature sensor and contactless switch etc. make the control convenience designs simplification, and can improve serviceability, and this controller can improve equipment interface and power adaptation.
Description of drawings:
Fig. 1 is the utility model used for rail vehicle air-conditioning control convenience structural representation.
Fig. 2 is the utility model functional block diagram.
Fig. 3 is that microprocessor controller able to programme is formed scheme drawing among Fig. 2.
