Thermal control device for prepaying with noncontact-type smart IC card

Abstract

The invention relates to a thermal control device for prepaying with a noncontact-type smart IC card, mounted in a thermal power station of a civil central heating system. The device mainly comprises a shell and components in the shell, i.e. a power supply, a contact-type operation controller, a noncontact-type smart IC card reader, public communication network modules of CDMA (Code Division Multiple Access) / GPRS (General Packet Radio Service) / ADSL (Asymmetric Digital Subscriber Line), and the like, an RS (Recommended Standard) 485 MOD-BUS communication module, an M-BUS heat meter communication module, a multi-branch electric valve control module, a multi-branch electric valve state detection module, and the like. By the device, the prepaying functions of the IC card for central heating, the storage of paying data, transaction records, heat consumption data, and the like can be realized. The device is used for collecting a heat meter according with an M-BUS communication standard protocol, transmitting partial data to local other smart equipment through an RS 485 interface and transmitting the information of the real-time data, the transaction records, the heat consumption data, and the like to an upper management system through communication interfaces of the public communication networks of CDMA / GPRS / ADSL, and the like so that heat supply enterprises can acknowledge the heat consumption requirements and the transaction conditions of heat users in time, and the modern management levels of the heat supply enterprises are improved.

Description

technical field [0001] The invention relates to heating (cold) metering control technology, in particular to a heat consumption control device utilizing non-contact intelligent IC card prepayment, which is used to realize prepaid management, control, alarm and remote monitoring etc. Background technique [0002] At present, the phenomenon that customers of urban heating companies in my country are in arrears of heating fees is very serious. It is urgent to adopt a more scientific charging management system to solve the existing problems, protect the legal rights of enterprises, improve the quality of heating supply, increase the charging rate, and reduce the operating risks of heating companies. Guarantee the safe and stable operation of the urban heating system, and realize the efficient, low-carbon, scientific and sustainable development of urban heating.
