Heat exchanging units long-range control system

Abstract

The invention relates to a heat-exchanger unit remote control system in the heat exchange control field, the technology is mainly characterized in that: the system is composed of a main control machine which is positioned at a control center, a modulation demodulator which is connected with a communication interface thereof, control boxes of heat-exchanger units which are distributed in each heat supply station and modulation demodulators which are connected with the communication interfaces thereof by connection via a public telephone virtual network, and the heat exchanger unit control boxes are connected with a temperature sensor in a heat supply pipeline, a pressure sensor, a regulating valve, a circulating pump, a water supplementing pump and an outdoor temperature sensor. The heat-exchanger unit remote control system can carry out the real-time monitoring and the control of the operation situations of all the heat-exchanger units, once the devices of the heat supply stations are detected to have the faults, the processing can be carried out immediately, thus ensuring the normal operation of a heat supply system, automatically adjusting the opening degree of the regulating valve of a primary network, avoiding the waste of the resources due to the excessive heat supply or the inconvenience of a user due to the insufficient heat supply and stably supplying the heat to the user of a secondary network.

Description

technical field [0001] The invention relates to the field of heat exchange control, in particular to a remote control system of a heat exchange unit. Background technique [0002] The heat exchange unit in the heating station is the central link for the thermal energy of the primary network to be transmitted to the users of the secondary network. Adjust the opening and opening of the regulating valve according to the pressure, outdoor temperature, etc., and control the water volume of the primary network water supply, so that the return water temperature of the secondary network meets the specified heating standards. At present, there is no connection between the various heating stations in a region or city. Each heating station only controls the heat exchange units in the station. Moreover, the heating stations use manual methods to adjust the primary network. The opening of the valve and the monitoring of the operating status of the equipment have problems such as heavy m...

Problems solved by technology

At present, there is no connection between the various heating stations in a region or city. Each heating station only controls the heat exchange units in the station. Moreover, the heating stations use manual methods to adjust the primary network. The opening of the valve and the monitoring of the operating status of the equipment have problems such as heavy monitoring workload and difficult control of the temperature, resulting in unstable return water temperature of the secondary network. If the temperature of the user in the secondary network is too high, it will cause thermal resources. Waste, if the temperature is too low, it will cause inconvenience to the daily life of users
