Please refer to Fig. 3, also proposed a kind of method realizing zonal control for centralized direct current street lamp in the another aspect of the present embodiment, coordinate the above-mentioned system realizing zonal control for centralized direct current street lamp to carry out zonal control, described method comprises:
S100: the planning of subregion, is divided into predetermined subregion by the shunt of direct current road lamp system according to demand;
S200: the typing of partition information, by the Data Enter of all subregions in system;
S300: arrange partition number, is set as corresponding partition number by the shunt that each section post comprises;
S400: be pressed into by partition information in command stack, system obtains control command from command stack, control command is through the order of high direct voltage coding module coating-forming voltage, and voltage commands drives high direct voltage order sending module to send order to streetlight unit;
S500: after streetlight unit takes orders, parses the partition number in this order, and judges that whether this partition number is consistent with the partition number of self, if unanimously, then responds this voltage commands, if inconsistent, then ignores this voltage commands.
Concrete, in the step s 100, the shunt of direct current road lamp system is the minimum composition unit of subregion, and a subregion at least will comprise a shunt, can comprise whole shunt at most, i.e. default partition.According to the actual requirements, the composition of definition subregion, namely subregion comprises how many shunt to owner, needs how many subregions.If owner only needs, all along separate routes at same subregion, only need close sectoring function, allow system works on default partition.
In step S200, after having planned subregion, before the configuration of boot partition, need first partition information to be entered into system.Operating personnel can carry out the typing of partition information by the monitoring unit of host computer or execute-in-place direct current road lamp system.The partition information of typing comprises: the information such as the switch lamp moment of subregion, the multistage light modulation state pause judgments moment of subregion and multistage light modulation ratio.After Data Enter, operating personnel are boot partition function (sectoring function unlatching) and zone configuration function successively.System carries out zone configuration automatically subsequently, and after zone configuration completes, system carries out work according to setting subregion automatically, namely automatically transfers normal mode of operation to.
In step S300, system enters zone configuration pattern, arranges partition number to subregion.In this stage, system can enter into zonal control module, judges whether to carry out zone configuration, if, then carrying out after zone configuration completes, entering normal mode of operation, if not, then directly enter normal mode of operation, carry out work according to set subregion, as shown in Figure 6.
Concrete, system carries out zone configuration flow process as shown in Figure 7, when being configured, first judge whether the number of partitions arranged is less than the total quantity of subregion, if so, then according to the composition of subregion, arrange corresponding closed along separate routes, subregion setting command enters command stack, then continues to judge whether the number of partitions arranged is less than the total quantity of subregion, until the number of partitions arranged equals the total quantity of subregion.
Concrete, the setting of described partition number comprises step:
The all shunt of system closing;
According to the composition only shunt that comprises of this subregion closed of subregion;
System sends partition number configuration order, and namely closed shunt is set to corresponding partition number.
Such as: first system closes all shunt, then according to the composition only shunt that comprises of closed subregion of subregion, then system sends the configuration order of subregion 1 to the streetlight unit in the shunt of partition group one-tenth, streetlight unit will receive life from now on, self is set to subregion 1, and preserve partition number, thus all streetlight units on subregion 1 are all set;
The following configure partition 2 of system, method is identical with configure partition 1 method.By that analogy, after system configures set all number of partitions automatically, more automatically proceed to normal work pattern, carry out the control of subregion.
In step S400, normal mode of operation uses 2 functional modules, and one is zonal control module, and one is high voltage direct current order sending module.In zonal control module, system judges whether sectoring function opens, if after opening, according to all subregions of subregion index (i.e. partition number) poll, Systematic selection is pressed into control command (after selectivity refers to the process that the system elapsed time judges, then determining which kind of control command press-in command stack) in command stack; If sectoring function is not opened, then the control command (partition number of default partition is 0) producing default partition is ordered into command stack, as shown in Figure 8.
Wherein, which kind of order is system, by checking whether current time dropped in the time period set in partition information, decide as command stack.System is preset with 3 time periods:
Turn on light to turning off the light the time period;
1 grade of light modulation is initial to end time section;
2 grades of light modulations are initial to end time section.
Such as current time has dropped on that 1 grade of light modulation is initial in end time section, and so system is just 1 grade of light modulation ratio, press-in command stack; Similar, if to have dropped on 2 grades of dimming time initial in end time section for current time, so system can 2 grades of light modulation ratios press-in command stacks.The primary operating parameter that control command comprises has:
Subregion forms;
The lighting time point of subregion (lighting time point and to turn off the light between time point be a time period, namely turn on light to turning off the light the time period);
The time point of turning off the light of subregion;
1 grade of light modulation ratio of subregion;
1 grade of light modulation start time point of subregion (1 grade of light modulation initial time and at the end of be a time period between punctum, namely 1 grade of light modulation is initial to end time section);
1 grade of desk lamp with dimmer switch time point of subregion;
2 grades of light modulation ratios of subregion;
2 grades of light modulation start time points of subregion (2 grades of light modulation initial times and at the end of be a time period between punctum, namely 2 grades of light modulations are initial to end time section);
2 grades of light modulation end time points of subregion.
After having control command to be sent in systems axiol-ogy to command stack, take out a control command, control command is through high direct voltage coding module coating-forming voltage order (as shown in Figure 4), and voltage commands drives high direct voltage module to send to streetlight unit; After streetlight unit receives voltage commands, first parse partition number (as shown in Figure 5), and judge that whether this partition number is consistent with the partition number that oneself is preserved.If partition number is consistent, then streetlight unit responds this voltage commands; Otherwise streetlight unit ignores this voltage commands.Wherein, high direct voltage coding techniques can referenced patent CN201410032298, and therefore not to repeat here.
To sum up, what provide in the embodiment of the present invention a kind ofly realizes in the method and system of zonal control for centralized direct current street lamp, first subregion is carried out to branched shunt, the typing of partition information, and set partition number, system obtains control command from command stack, and the corresponding high direct voltage order sending module that drives sends voltage commands to streetlight unit, streetlight unit can judge that whether the partition number in this voltage commands is consistent with the partition number of self, if consistent, then respond this voltage commands, if inconsistent, then ignore this voltage commands, thus realize zonal control, without the need to extra communication module, with low cost, and system stability is reliable.
