Problems solved by technology

However, due to the different operating temperatures of the vehicle heating system, it often needs to be turned on and off. Therefore, the traditional circulation pump manually controlled by the operator is no longer suitable for the needs of existing vehicles, and better technology needs to be applied to the vehicle field.

Abstract

The invention provides a control device and control method of a heating system of a coal power boiler for a vehicle. The temperature in a vehicle compartment is measured through a temperature sensor, a water temperature sensor is used for measuring the temperature of circulation water in the boiler, and a control system controls the gear of an electric heater to be added or reduced, controls a circulation pump to be started or stopped, and controls over water shortage protection, anti-boiling protection and alarming for insufficient heating according to the temperature of the vehicle compartment and the water temperature. When a circulation water pump in a room is lower than a set temperature and the outlet water reaches a certain temperature, the circulation pump is started so as to improve the average temperature of a radiator, and the effect of improving the temperature in the vehicle compartment is achieved. When the indoor temperature reaches the set temperature or the water temperature is too low, the circulation pump is stopped, and automatic control of the heating system is achieved. By means of the device and method, the effect of automatically switching natural circulation and forced circulation of the vehicle heating system is achieved, and work efficiency for frequently starting or stopping the electric heater and the water pump is improved.

Description

Technical field [0001] The invention relates to a control device and a control method of a heating system in the field of vehicle manufacturing, in particular to a control device and a control method of the heating system of a coal-fired boiler for vehicles. Background technique [0002] At present, the control method of the vehicle boiler heating system usually adopts the heater in the boiler to set several gears, which is manually operated by the operator to make the heater in the boiler execute the corresponding heating gear. In this way, not only the workload of the operator is increased virtually, but also misoperation is likely to occur during the operation, which in turn leads to an increase in the accident rate. [0003] At the same time, due to the laying of vehicle lines in cold areas, the requirements for the vehicle heating system are higher. This requires the addition of a circulating pump to the vehicle heating system to increase the working efficiency of the vehicle...
