Embodiment
Describe an optimum embodiment of the present invention now in detail.With reference to accompanying drawing, identical numbering is represented identical parts in institute's drawings attached.As employed in the instructions here and whole claims, following term has and the clear and definite related connotation of the description here, unless the style of writing spell out other connotation: " one " and the connotation of " this " comprise plural reference, and " ... interior " connotation comprise " ... interior " and " ... on ".
Fig. 1 has illustrated a computer system 10, and this system has an integrated energy system 12 on system communications bus 4.Computer system 10 appears at one such as cell phone, needs in the mancarried electronic aid such as the active energy management system of battery charge.Also can at random be embodied as an independent computer system 10 and energy system 12 though illustrated computer system 10 comprises 12, one equipment of energy system here, perhaps only be realized as an energy system 12.Energy system 12 comprises a plurality of such as electric battery 16, analyzer 18, wireless device 20, desktop charger 22, the energy device of desktop charger display 24 or other energy system equipment 20, each energy device all are integrated on the system communications bus 14 and may communicate by letter by bus 14.System communications bus 14 allows to carry out the half-or full-duplex multi-point between energy device, thereby each equipment all can communicate dialogue by communication bus 14 and miscellaneous equipment.
Energy device all comprises an energy device processor, make each energy device processor communication data idle condition of surveillance communication bus 14 selectively, promptly the current not using system of the miscellaneous equipment of the computing machine shown in square 28 communication bus 14 transmits data.Energy device preferably also comprises a storer, the data that this storer can stored energy equipment, but and can be sent to miscellaneous equipment to data in 14 times spent of communication bus.The energy device processor can be any processor, microcontroller and a microprocessor as known in the art.When not having communication data on the system communications bus 14, each energy device 16,18,20,22,24,26 is all attempted other energy device 16,18,20,22,24,26 communications with energy system 12 on an optimal ordering discussed here and the system communications bus 14.Then the miscellaneous equipment on the best polling system communication bus 14 of energy device transmits to have determined whether that any energy system device data is submitted to.
With reference to Fig. 2, wherein show the serial supervision of energy device and the best protocol of serial communication.Shown in step 34, each energy device 16,18,20,22,24,26 equal surveillance communication buss 14 are so that transmit data stream by system communications bus 14.Should be noted that energy device can detect communication data with a positive edge or marginal edge trigger.Then make a judgement shown in 36 to determine whether activity is arranged on bus 14, whether cellular communication data is promptly arranged as adjudicating.If communication data stream is arranged, then shown in step 38, equipment is waited for the schedule time under an idle condition, and follows once more the communication data on the surveillance communication bus 14, promptly turns back to step 34.But in the frequent monitor communication bus 14 of equipment, under the situation of the utmost point short cycle monitor communication bus 14 of promptly frequent supervision or interval such as some microseconds, the monitored state of step 34 and the idle condition of step 38 can be same steps as.Otherwise, carry out circulation time in monitoring step and can enter a waiting status.
Again the exemplary predetermined free time before the surveillance communication bus 14 is as follows:
Wireless device 20:10 millisecond+/-499 millisecond
Desktop charger 22:11 millisecond+/-499 millisecond
Desktop charger display 24:12 millisecond+/-499 milliseconds
Analyzer 18:13 millisecond+/-499 millisecond
Other energy system equipment 26:14 millisecond+/-499 milliseconds
The importance of above-mentioned step sequence is, serial monitor communication bus 14 is not so that equipment can detect the surveillance operation of miscellaneous equipment and can not miss communication activity on the monitoring wire.Like this, finish supervision to the energy device of communication bus 14 up to serial, the real time between the equipment of monitor communication bus 14 at interval only need be greater than a time interval that is enough to not disturb the supervision of another equipment.Thereby can find can be added to easily in the serial protocol such as other energy device of electric battery 16, the idling cycle that wherein monitors is 1 millisecond, early than or be later than the shortest or longest-idle of existing equipment in the energy system 12.
Referring again to judgement 36, if 14 free time of system communications bus, then shown in step 40, energy device is attempted communicating by letter with the miscellaneous equipment in the energy system 12 in order.The optimal transmission agreement with a pulse to start with so that make all external data device reset of energy system 12.Each energy device produces the example of timing sequence of a reset pulse on communication bus 14 as described below:
Wireless device 20:574 millisecond+/-10 millisecond
Desktop charger 22:553 millisecond+/-10 millisecond
Desktop charger display 24:532 millisecond+/-10 milliseconds
Analyzer 18:511 millisecond+/-10 millisecond
Other energy system equipment: 490 milliseconds+/-10 milliseconds
Serial at communication bus 14 monitors, needs the series arrangement reset pulse so that equipment is not attempted simultaneously by communication bus 14 communications and generation data collision.As a result, above-mentioned sequence is the simple declaration of avoiding the sequence of data collision to one, and can use the interval At All Other Times between reset pulse or the communication arbitrarily.
An example of communication bus 14 controls is that when an electric battery was placed in the desktop charger 22, charger 22 changed to a particular state such as high idle condition to bus 14.If communication bus 14 is idle on a high state, then low status detection of a free time is shown charger 22 not occur or do not communicate by letter, and a system equipment that is different from charger when communicating by letter, needs can take bus 14.But when finishing communication by bus 14, energy device must forbid this drawing high.Can use other communication bus 14 control methods as known in the art in the present invention arbitrarily.
After reset pulse, as adjudicate shown in 42, energy device can determine whether system communications bus 14 has activity, and promptly surveillance communication bus 14 is to determine whether to flow through the data of system communications bus 14.If on the system communications bus 14 communication activity is arranged, then energy device must be supposed on system communications bus 14 data circuits communication data, an idle condition wait for once more the schedule time (step 38) and/or after predetermined free time the communication data of monitor bus 14.If do not have communication data on the system communications bus 14 after reset pulse, then shown in step 44, system equipment can send data by system communications bus 14.Substantially, of the present invention owing to having, by energy device 16,18,20,22,24,26 serial supervision and the host-host protocols that use when communicating by system communications bus 14, energy system equipment can take system communications bus 14 under the situation that does not have very high data collision possibility.In case energy system equipment sends communication datas by system communications bus 14, then equipment returns the communication data of surveillance communication bus 14 or from the data of another energy system equipment, promptly turns back to step 34.
When polling system communication bus 14 in judgement 42 with when detecting communication data, desktop charger 22 is interrupted any arrival or also is optimum from the charge or discharge electric current of electric battery 16.By making charging current flow through other parts of computer system 10, such action makes electromagnetic interference (EMI) (EMF) minimum of not expecting.But disturb in the very little system at the EMF of charging current and other, needn't forbid charging current during the communication data of desktop charger 22 on detecting communication bus 14.
An optimum embodiment of the present invention has been described in the front, should be appreciated that can want prime form and arrange and carry out some change under the prerequisite that does not depart from described fundamental purpose of the present invention such as claims and scope.
