Accompanying drawing explanation
Fig. 1 is the structural representation of the integrated collecting device of the many physical quantitys of the present invention.
Embodiment
As shown in Figure 1, remote monitoring server and the multiple physical quantity transducers at Pollution Source Monitoring point are comprised at long-range pollution monitor system.The integrated collecting device of a kind of many physical quantitys, the integrated collecting device of this many physical quantity comprises multiple collection subelement (Remote Sensor, RS), each collection subelement RS includes web-transporting device, also comprise MCU, this MCU not only for controlling the acquisition time of transducer and the transfer of data between web-transporting device and the corresponding sequential that gather physical quantity, but also calculates the difference between physical quantity that the current physical quantity that collects and last time collect.In the ordinary course of things, only by this differential transmission to web-transporting device so that reduce Internet Transmission load.
Described web-transporting device is for transmitting the physical quantity that this collection subelement RS collects, described physical quantity difference computational unit for calculate current detection to physical quantity and the physical quantity that detects of last time between difference, the integrated collecting device of this many physical quantity to the web-transporting device that uses of remote monitoring server transmission data as master network transmission equipment, and described web-transporting device has network throughput computing unit, the result of calculation of the network throughput computing unit that the integrated collecting device of described many physical quantitys gathers on subelement RS according to each determines the web-transporting device that the integrated collecting device of this many physical quantity uses to remote monitoring server transmission data, after this master network transmission equipment of each change, by web-transporting device and the remote monitoring server as new master network transmission equipment carry out first time communicate time, all the partial data of the physical quantity collected is sent to remote monitoring server.
According to a preferred embodiment of the invention, the current network throughput of each RS to be stored in respective memory and real-time update.This real-time throughput situation can be saved the form into load balance table or load level table.Certainly, also other data structure can be saved into.
Because remote monitoring server is different to the frequency acquisition demand of various different physical quantity, and because the time length obtaining these physical quantitys itself when gathering various physical quantity required is different, therefore, in same amount of time, the data that each RS sends are generally different, and the physical quantity kind gathered is more, and this situation is more complicated.Such as, RS comprises gaseous contamination source transducer, liquid stain sources transducer, solid pollution source transducer and/or Contamination of Electromagnetic Wave source transducer.
To include fields at described load level table: hierarchical level value (Water Level), higher limit (Up Limit), warning value (Trap Up), with lower limit (Low Limit).Is the hierarchical level height low value of described access point shown by hierarchical level value field, when higher limit, warning value then represent at described hierarchical level respectively with the numeral in lower limit field preset the upper limit of corresponding tolerable load capacity, warning and lower limit.In the present embodiment, described load capacity (comprise tolerable load capacity with after a while by carry with real time load amount) can be the corresponding terminal quantity that links at described access point or the data traffic transmitted one of them.Such as, when hierarchical level value is higher, then the upper limit of the tolerable load capacity of described access point, warning and lower limit are also higher, are so the tolerable load capacity representing that described access point can provide higher.In the present embodiment, the size of the lower limit of each hierarchical level value is between the warning value and lower limit of the hierarchical level value of low one-level; Further, the size of the higher limit of each hierarchical level value is between the warning value and lower limit of higher leveled hierarchical level value.So, when no matter the real time load amount (momentary load amount when namely operating) of a certain access point is the upper limit because reaching residing hierarchical level value at that time or lower limit and is raised or turns down a hierarchical level, between the warning value that its real-time load capacity all will drop on upper level or next stage and lower limit.
Rely on and suitable setting carried out to network administration apparatus, optionally net control management devices regularly (such as every a few minutes) initiatively check the load balanced state of each group or the connecting state of each access point or real time load amount.Further, according to the result checked, control the hierarchical level value with the tolerable load capacity adjusting certain access point, or change certain access point group's configuration, to improve load balanced state, and then promote the whole efficiency of Radio Network System.
In other embodiments of the invention, the real time acquiring method of above-mentioned network throughput also can be obtained by principle mentioned in the background technology of such as Chinese invention patent application CN200710160974.
In actual use, the network throughput of certain RS can be determined according to the mean value of above-mentioned hierarchical level value.
In the fixing cycle is arranged, broadcasted by the network throughput of all RS at regular intervals, each RS all compares, and what wherein network throughput was minimum will by as main network transmission equipment, and other RS will send data from this RS of trend.
Alternatively, above-mentioned multiple sub-collecting unit RS also comprises network transmitting unit respectively, and this network transmitting unit is used for replacing this web-transporting device when web-transporting device breaks down.
Alternatively, described multiple collection subelement RS also comprises GPS transducer, for often organizing physical quantity measured value mark timestamp and locating information.Contribute to the reliability improving data acquisition like this, avoid the interference of human factor.
Alternatively, described multiple collection subelement RS also comprises alarm, for being sent with the form of sound and/or light by the fault message gathering subelement RS.This scheme can help field maintenance person to know abnormal operating state as early as possible, carries out the maintenance of the transducer of RS or the replacing of power supply (such as battery).
As shown in Figure 1, described network transmitting unit and web-transporting device adopt WLAN networking.Alternatively, mode that is fixing or dynamic IP can also be all adopted to communicate with remote monitoring server between them.
The mode illustrated with word and accompanying drawing above illustrates the structure of some embodiments of the present invention, not exhaustive or be limited to concrete form described above.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
