Description

A kind of intelligent room control system

Technical field

The utility model relates to a kind of intelligent room control system, and the single guest room system of this system can support networking of CAN bus and Ethernet networking, multichannel relay output simultaneously or light modulation output simultaneously.

Background technology

At present the hotel all generally uses room control system to manage numerous rooms, and the mode by networking realizes the supervision to all rooms on host computer, though existing intelligent room control system is fairly perfect, and the deficiency below the existence still:

1) aspect networking or only support CAN bus networking, only support the Ethernet networking, and because the CANBUS of each producer application at present all is a SJA1000 chipset scheme of directly using Zhou Ligong company, this scheme provides circuit diagram, source code and the complexity setting of having hidden CANBUS, but preceding summary takies the resource of a single-chip microprocessor MCU, therefore the new MCU of adding that wants correspondence is as networking MCU, with the light steering logic between a MCU management house, realization is to the supervision in room, another MCU and SJA1000 form the CANBUS networking, and the TCP scheme that Ethernet adopts is directly used general MCU+RTL8019 especially.Therefore so long as interconnection type can not be less than two MCU;

2) on data transmission, generally or only support the point-to-point input of single fixed number, or only support the input of 485 buses;

3) because the main frame of existing room control system has just been fixed the feeder number that relay and controllable silicon are exported at the beginning of design, if the controllable silicon output loop then can not be dealt with inadequately midway, therefore limitation is big aspect output load, and relay output loop number and controllable silicon output loop number immobilize.

Summary of the invention

Problem to be solved in the utility model is: existing intelligent room control systems connection mode is single, and data transfer mode is restricted.

The technical solution of the utility model is: a kind of intelligent room control system, be arranged in the guest room, comprise the CANBUS controller, the TCPIP controller, the RS485 bus controller, point-to-point input/output control module, single-chip microcomputer, the 30A relay, No. 19 relays or controllable silicon light modulation output module and host computer, the CANBUS controller, the TCPIP controller, the RS485 bus controller, point-to-point input/output control module is connected with single-chip microcomputer is two-way respectively, the control input end of 30A relay and No. 19 relays or controllable silicon light modulation output module connects the output terminal of single-chip microcomputer, wherein by CAN bus and Ethernet and host computer networking, the RS485 bus controller connects all RS485 peripheral hardwares in the guest room respectively for CANBUS controller and TCPIP controller; Point-to-point input/output control module connects all point-to-point peripheral hardwares in the guest room; The 30A relay connects the controlled source socket in guest room.

Guest room RS485 peripheral hardware comprises RS485 bus temperature controller, RS485 identification electricity-getting switch and RS485 bus input and output enlargement module; The point-to-point peripheral hardware in guest room comprises echo switch, human body infrared detector, the magnetic approach switch of crawl.

The utility model be a kind of integrated level high, drive easily, the intelligent flexibly room of networking control system, as long as a slice single-chip microcomputer, by No. 19 relays or controllable silicon light modulation output module with the controllable silicon loop be packaged into can with the form of relay exchange, so can be in 19 tunnel scopes free selective relay output or controllable silicon export.
