For fully understanding the present invention, with reference to the accompanying drawings of the preferred embodiments of the present invention.Embodiments of the invention can be deformed into various forms, and scope of the present invention shall not be construed as the embodiment that is defined in following detailed description.The present embodiment is provided for, to those skilled in the art, the present invention is described more completely.Therefore, more particularly bright in order to emphasize, the shape of the key element in accompanying drawing etc. likely can show turgidly.It should be noted that in each accompanying drawing, exist identical member to carry out illustrated situation with identical reference marks.In addition, omit judgement is thought to the detailed description of known function and the formation that may unnecessarily obscure main idea of the present invention.
With reference to the accompanying drawings, further describe the preferred embodiments of the present invention.
Fig. 2 is the skeleton diagram that shows the formation of wireless each room control system of the BCM of utilization of the present invention.
As shown in Figure 2, the present invention includes: the several each room controller 110 that is installed on each room; Each room valve positioner 120, it receives signal from main room controller, regulates the aperture of each room valve; Main room controller 100, it receives the data about the current state of described each room controller 110 and each room valve positioner 120, stores these data and shows, controls thus each room valve positioner 120 and each room controller 110; And BCM130, it is connected with described main room controller 100 by PLC, and the control signal of main room controller is sent to boiler 140.
Described main room controller 100 possesses wireless communication part 102 for communicating by letter with each room valve positioner 120 and each room controller 110 and plc communication portion 101 for communicating by letter with BCM130, in order to carry out boiler 140 and each room valve 122 is controlled required data processing and built-in miniature computing machine 103.In addition, comprise display part and the key input part 104 towards user.
Particularly described main room controller 100 obtains power supply supply from described BCM130, thereby without possessing other power supply unit, even under larger current drain, also can stably control each room system.
Described each room valve positioner 120, from described main room controller 100 reception control signals, is controlled the driver that each room valve opening is regulated, for possessing wireless communication part with described main room controller 100 radio communications.
Described each room controller 110 is arranged at each room, and for control the heating in each room according to user's operation, for communicating by letter and possess wireless communication part 111 with described main room controller 100, power supply unit 112 embodies with cell type.
Described BCM130 comprises for communicating by letter with main room controller 100 and the 1st Department of Communication Force 131 of power line communication (PLC) mode of electric power supply and the 2nd Department of Communication Force 132 for communicating by letter with boiler.
Generally speaking, boiler or each room control system are used each manufacturer intrinsic communication protocol separately, described the 2nd Department of Communication Force 132 is in adopting the communication protocol of the communication protocol same size using with the boiler of any kind, adopt general communication protocol, even also can communicate by letter in the time that communication protocol is different.
Particularly, in the time that communication protocol is different, realize intercommunication mutually by general RS-485 communication module, now, can utilize DIP switch built-in in BCM or automatic identifying method, according to the contact state of boiler, contact value is changed to A contact or B contact.
On the other hand, described BCM130, as module, can pass through other device, is connected between boiler 140 and main room controller 100, or is combined into a part for main room controller 100.
Fig. 3 is the process flow diagram that shows the applied time-division transmitting-receiving of radio communication mode between main room controller of the present invention and each room controller.
As shown in Figure 3, between main room controller 100 and each room controller 110, in radio communication, each room controller 110 is accepted respectively intrinsic ID and is distributed, and divides out by each ID the transmitting-receiving cycle of setting.Then, wake up according to the cycle of self, attempt and main room controller 100 radio communications, receive ack signal from main room controller 100, or be converted to sleep pattern after the end cycle of self.
By using this transmitting-receiving mode, thus can prevent data from transmitting simultaneously and contingent communication failure in possible trouble, reduce the wakeup time of each room controller 110, reduce unnecessary battery consumption.
On the other hand, each room controller 100 is with main room controller 110 in the time of radio communication, and use transmits the retry transmitting-receiving mode that sends grouping for 5 times, thereby while making radio communication, contingent data transmission errors realization minimizes.
In addition, described each room controller 110 periodically checks battery status value, if battery remaining surplus is reduced to below set value, battery altering pilot lamp is lighted, allow user can know like a cork battery altering opportunity, described main room controller 100 periodically checks the communications status of each room controller 110, in the time more than 240 seconds cannot communicating by letter, starts enforced opening/the close function of the valve driver in corresponding room at main room controller.
Implementation column of the present invention described above is example, as long as those skilled in the art just can understand, can derive thus various distortion and other impartial embodiment.Therefore can understand, the present invention is not only limited to the form mentioning in described detailed description.Therefore, the real technical protection scope of the present invention should be determined according to the technological thought of claims.In addition, it will be appreciated that as the present invention includes all deformations and equipollent and the sub in spirit of the present invention and the scope thereof in defining according to claims.
