Detailed description of the invention
For making object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is described in further detail.Should be appreciated that detailed description of the invention described herein only in order to explain the present invention, do not limit protection scope of the present invention.
The wireless schematic flow sheet from method for numbering serial of hydraulic support electrohydraulic control system of the present invention in an embodiment has been shown in Fig. 1.As shown in Figure 1, the method in the present embodiment comprises step:
Step S101: current brackets controller obtains self numbering;
Step S102: judge that whether self is main website, if main website, enters step S103 according to self numbering described, default master-salve station decision rule;
Step S103: search the bracket controller not obtaining numbering in self coverage, and connect with the bracket controller not obtaining numbering searched, obtain the distance between self and the bracket controller respectively not obtaining numbering;
Step S104: according to distance order from the near to the remote, described self numbering, preset numbers Cahn-Ingold-Prelog sequence rule, in the bracket controller not obtaining numbering and self nearest preset number bracket controller be numbered.
According to the scheme of the embodiment of the present invention as above, it is after bracket controller obtains numbering, if it is main website, can connect by other bracket controllers not yet obtaining numbering automatically and in its coverage, and these bracket controllers are numbered, based on self numbering of default master-salve station decision rule and acquisition, relevant bracket controller becomes main website automatically, circulation like this, achieve the automatic numbering to bracket controller, without the need to manually arranging bracket controller one by one, decrease installation workload, reduce the probability of numbering and makeing mistakes.
When implementing the scheme of the embodiment of the present invention, the inside of the bracket controller of each hydraulic support is all built-in with wireless device, this wireless device has normal radio communication function, and can be adopt any possible communication to carry out radio communication, distance between bracket controller and current brackets controller, also can adopt and anyly can determine that the mode of distance is determined.
It should be noted that, because hydraulic support is used in the fully-mechanized mining working in colliery, therefore, when determining the distance between bracket controller and current brackets controller, the conventional localization methods such as GPS (GlobalPositioningSystem, global positioning system) can not be used to determine.
Therefore, in an embody rule example, this wireless device can be the radio communication device based on UWB (UltraWideband is a kind of carrierfree communication technology), is namely communicated by UWB between each bracket controller.UWB can realize the message transmission rate of hundreds of Mbit/s to number Gbit/s in the scope of about 10 meters, there is strong anti-interference performance, transfer rate is high, very bandwidth is wide, consume the many advantages such as electric energy is little, transmitted power is little, thus can make, between bracket controller, there is higher communication performance.The more important thing is, UWB can realize accurate geographic location, possesses the function of range finding, thus by just can realize radio communication and these two functions of finding range at the built-in radio communication device based on UWB of bracket controller simultaneously.
In a concrete example, as shown in Figure 1, obtain the distance between self and the bracket controller respectively not obtaining numbering in above-mentioned steps S103 after, before step S104 pair and self nearest preset number bracket controller are numbered, can also step be comprised:
Step S1034: judge with self nearest preset number bracket controller and self distance whether within the scope of corresponding predeterminable range, if, then enter step S104, to in the bracket controller not obtaining numbering and the step that is numbered of self nearest preset number bracket controller, if not, then warning information is sent.
In the case, by the distance between each bracket controller being in a specific preset range, (namely any main frame is not more than corresponding predeterminable range scope with each distance between machine in its coverage, such as be not more than a corresponding predeterminable range scope with nearest one from the distance of machine, another corresponding predeterminable range scope is not more than from the distance of machine with nearest second, other are by that analogy), can so that reasonably arrange the distance of each hydraulic support, be conducive to main website to each control from machine in its coverage.When adopting the radio communication device based on UWB, can also guarantee and play the advantage of the communication performance of UWB further.
Wherein, above-mentioned default master-salve station decision rule, based on different Considerations, can set in different ways.Sequence schematic diagram below in conjunction with the mounting arrangements of the bracket controller of the hydraulic support shown in Fig. 2 is example, carries out example explanation with regard to wherein several different master-salve station decision rule.
Concrete example one
In this concrete example, above-mentioned default master-salve station decision rule can be the main website numbering collection preset, and when the numbering that bracket controller obtains is this main website numbering concentrate, then can assert from as main website, otherwise be slave station.This main website numbering collection can be when installing the bracket controller of hydraulic support, is equipped with this main website numbering collection in all bracket controllers.
In this concrete example, the bracket controller of each hydraulic support prestores main website numbering collection, and each bracket controller is after the numbering obtaining self, judge whether self numbering is present in this main website numbering and concentrates, if so, then judge certainly as main website, otherwise be slave station.
After by the bracket controller installation of all hydraulic support, all bracket controllers are slave station, and install by certain distance linear array, and all bracket controllers all there is no numbering, are in the state of intercepting, and initiatively outwards do not send data.Each bracket controller is built-in with one based on the wireless device of UWB, and this wireless device, except normal wireless telecommunications, also possesses the function of range finding.Bracket controller is divided into master station and follow station, and both are by software exchange, and main website can connect with the website covered automatically, and obtain and cover distance between website, transmission numbering Frame is numbered other websites.Suppose the bracket controller open numbering from N frame (first frame or last) hydraulic support, and number order is fixedly installed in each bracket controller as increasing or decreasing, in this example, is described to increase progressively.
Because support model is different, on-the-spot at each work plane, distance between each bracket controller is not identical yet, so the bracket controller quantity that main website can cover has difference, therefore need the number to the website that each main website can cover (i.e. above-mentioned preset number) to arrange, suppose the preset number x=3 of the website that each main website can cover, 4,5,6,7.In this concrete example, in each bracket controller, this preset number can be prestored in advance.
After choosing the bracket controller of open numbering, the numbering of this bracket controller is set to the initial number (being assumed to be N) set, this initial number and above-mentioned main website number and collect relevant, owing to being number by incremental order, therefore, this initial number should be the minimum value that main website numbering is concentrated.It will be understood by those skilled in the art that if adopt serial number of successively decreasing, this initial number should be then the maximum value that main website numbering is concentrated.
After this bracket controller N obtains this initial number, because this initial number is a member that main website numbering is concentrated, thus automatically become main website, and search the bracket controller not obtaining numbering in self coverage, and connect with the bracket controller not obtaining numbering searched, obtain the distance between self and the bracket controller respectively not obtaining numbering, and determine the preset number nearest with self bracket controller.With self nearest this preset number bracket controller with when self distance is all within corresponding predeterminable range scope, then this bracket controller N is numbered for this preset number bracket controller.Suppose that preset number is 5, as shown in Figure 2, then this preset number bracket controller be N+1, N+2 ..., N+5, based on the coding rule increased progressively, it is corresponding be numbered N+1, N+2 ..., N+5.Bracket controller N enters normal operating conditions after numbering completes.
Bracket controller be N+1, N+2 ..., N+5 is after obtaining self numbering, self numbering is compared with main website numbering collection, judge whether self numbering is concentrated in this main website numbering, if not, be slave station, then automatically enter duty, if so, then automatically become main website, perform the process similar with above-mentioned bracket controller N, for other bracket controllers numbering not obtaining numbering in its coverage, and enter normal operating conditions after numbering completes.
Repeat said process, thus the numbering to all bracket controllers can be realized.Collect for { N, N+5, N+10 with main website numbering ... be example, the result after having numbered is as shown in Figure 3.
After numbering completes, the bracket controller N as server regularly can send heartbeat packet to whole system, and monitors the system failure based on the feedback of heartbeat packet, if broken down, then carries out alarm.
In addition, in system operation, each bracket controller as main website can also monitor the duty of a preset number bracket controller of self numbering, and any one in a preset number bracket controller of self numbering is when breaking down, send warning message, be convenient to carry out Breakdown Maintenance.
In addition, each bracket controller as main website can also every predetermined amount of time, detect a preset number bracket controller and the distance between self of self numbering, the distance detected is sorted, and judge whether this sequence mates with the numbering of the above-mentioned preset number of self a numbering bracket controller, if do not mate, then according to distance order from the near to the remote, self numbering above-mentioned, preset numbers order, in self coverage and self nearest preset number bracket controller re-start numbering.
Concrete example two
In this concrete example, this default master-salve station decision rule also can be preset main website numbering collection, when the numbering that bracket controller obtains is this main website numbering concentrate, then can assert from as main website, otherwise be slave station.Be with the difference of above-mentioned concrete example one, this main website numbering collection can be in numbering process, obtains from for its main website numbered.
In this concrete example, the bracket controller of each hydraulic support, when obtaining the numbering of self, obtains simultaneously and obtains main website numbering collection from for its main website distributing numbering, and judge whether self numbering is present in this main website numbering and concentrates, if so, then judge certainly as main website, otherwise be slave station.
After by the bracket controller installation of all hydraulic support, all bracket controllers are slave station, and install by certain distance linear array, and all bracket controllers all there is no numbering, are in the state of intercepting, and initiatively outwards do not send data.Each bracket controller is built-in with one based on the wireless device of UWB, and this wireless device, except normal wireless telecommunications, also possesses the function of range finding.Bracket controller is divided into master station and follow station, and both are by software exchange, and main website can connect with the website covered automatically, and obtain and cover distance between website, transmission numbering Frame is numbered other websites.Suppose the bracket controller open numbering from N frame (first frame or last) hydraulic support, and number order is fixedly installed in each bracket controller as increasing or decreasing, in this example, is described to increase progressively.
After choosing the bracket controller of open numbering, using this bracket controller as server, main website numbering collection is set, and the numbering of this bracket controller is set to the initial number (being assumed to be N) of setting, this initial number is a member that above-mentioned main website numbering is concentrated, owing to being by incremental order numbering, therefore, this initial number should be the minimum value that main website numbering is concentrated.Be understandable that, if adopt serial number of successively decreasing, this initial number should be then the maximum value that main website numbering is concentrated.
After this bracket controller N obtains this initial number, because this initial number is a member that main website numbering is concentrated, thus automatically become main website, and search the bracket controller not obtaining numbering in self coverage, and connect with the bracket controller not obtaining numbering searched, obtain the distance between self and the bracket controller respectively not obtaining numbering, and determine the preset number nearest with self bracket controller.With self nearest this preset number bracket controller with when self distance is all within corresponding predeterminable range scope, then this bracket controller N is numbered for this preset number bracket controller.Suppose that preset number is 5, as shown in Figure 2, then this preset number bracket controller be N+1, N+2 ..., N+5, based on the coding rule increased progressively, it is corresponding be numbered N+1, N+2 ..., N+5.Bracket controller N enters normal operating conditions after numbering completes.
Wherein, bracket controller N for bracket controller N+1, N+2 ..., N+5 numbering time, simultaneously to bracket controller be N+1, N+2 ..., N+5 sends numbering parameters information, include above-mentioned main website numbering in this numbering parameters information and collect.Wherein in an application example, above-mentioned preset number can also be included in this numbering parameters information, thus each bracket controller is without the need to prior preset preset number, the number (i.e. this preset number) of the slave station that the bracket controller as main website can cover can be arranged more flexibly.
Bracket controller be N+1, N+2 ... N+5 is after the numbering obtaining self and this numbering parameters information, self numbering is compared with main website numbering collection, judge whether self numbering is concentrated in this main website numbering, if not, be slave station, then automatically enter duty, if, then automatically become main website, perform the process similar with above-mentioned bracket controller N, be other bracket controllers numbering not obtaining numbering in its coverage, and enter normal operating conditions after numbering completes.
Repeat said process, thus the numbering to all bracket controllers can be realized.Collect for { N, N+5, N+10 with main website numbering ... be example, the result after having numbered is as shown in Figure 3.
Concrete example three
In this concrete example, this default master-salve station decision rule is determined from the information of coming for its Host Transfer of numbering.When the numbering that bracket controller obtains meets the rule condition determined based on these information, then can assert certainly as main website, otherwise be slave station.The concise and to the point schematic flow sheet of this example is correspondingly show in Fig. 4.
After by the bracket controller installation of all hydraulic support, all bracket controllers are slave station, and install by certain distance linear array, and all bracket controllers all there is no numbering, are in the state of intercepting, and initiatively outwards do not send data.Each bracket controller is built-in with one based on the wireless device of UWB, and this wireless device, except normal wireless telecommunications, also possesses the function of range finding.Bracket controller is divided into master station and follow station, and both are by software exchange, and main website can connect with the website covered automatically, and obtain and cover distance between website, transmission numbering Frame is numbered other websites.
Because support model is different, on-the-spot at each work plane, distance between each bracket controller is not identical yet, so the bracket controller quantity that main website can cover has difference, therefore need the number to the website that each main website can cover (i.e. above-mentioned preset number) to arrange, suppose the preset number x=3 of the website that each main website can cover, 4,5,6,7.
Suppose the bracket controller open numbering from N frame (first frame or last) hydraulic support, the bracket controller of one total M+1 frame hydraulic support needs numbering, and number order is likely increase progressively or successively decrease, it should be numbered by the order increased progressively or by the order of successively decreasing that each bracket controller is not known in advance.For number order for increasing progressively, each bracket controller fitting arrangement as shown in Figure 2.
After installation is complete, manually arranging N frame bracket controller is server, and in server, arrange numbering parameters information: the initial number N of the bracket controller of initial number, preset numbers Cahn-Ingold-Prelog sequence rule (increasing or decreasing), preset number (i.e. each support website quantity that can cover: preset number x).Wherein, the number M still needing the residue bracket controller of numbering outside the bracket controller removing described initial number can also be included in this numbering parameters information, this number M can judge in order to the accuracy of the numbering to system, is setting forth in detail in the explanation of subsequent example.
When setting above-mentioned numbering parameters information, if set number order rule as successively decreasing, can also determine whether N-M is greater than 0 further, if not, then do alarm.If so, then continue to perform follow-up process.In numbering process, numbering parameters information can send to remaining stents controller.
After numbering parameters information is provided with, server (i.e. bracket controller N) automatically obtains numbering ID, and the support at this numbering and place is number corresponding, and be N, thus automatically become main website, N bracket controller has been numbered.
After N bracket controller becomes main website, start the website (i.e. bracket controller) searched in oneself coverage, connect with the website searched, obtain the distance between self and website, adjust the distance near to far sorting, and whether nearest x the website of judging distance oneself and oneself distance be within the scope of corresponding predeterminable range, if not, then send warning information, point out.If all within the scope of the predeterminable range of correspondence, then according to the order near to far away, the Frame that numbering is set is sent successively to this x website, numbering ID is that No. ID of main website adds one successively, namely the numbering of this x website be followed successively by N+1 ..., N+x (is understandable that, when preset numbers Cahn-Ingold-Prelog sequence rule is for successively decreasing, then for subtract one successively, the numbering of this x website be followed successively by N-1 ..., N-x).When sending the Frame of numbering, above-mentioned numbering parameters information sends to this x main station controller by main website simultaneously.The external numbering work of N main website completes, and enters normal operating conditions.
Obtain numbering N+1 ..., whether N+x bracket controller can analyze based on oneself numbering be main website.Be specially, judge whether the numbering of oneself meets N+k*x (k=0,1,2,3,4 ...) (being understandable that, if successively decrease, then should be N-k*x), if do not met, being then slave station, if met, is then main website.The slave station obtained after numbering enters normal operating conditions, and no longer frame is searched in response.
N+x bracket controller is automatic after obtaining numbering becomes main website from slave station, search the website not obtaining numbering in oneself coverage, connect with the website searched, obtain the distance between self and website, adjust the distance near to far sorting, and whether nearest x the website of judging distance oneself and oneself distance be within the scope of corresponding predeterminable range, if not, then send warning information, point out.If all within the scope of the predeterminable range of correspondence, then according to the order near to far away, oneself x website that be nearest, that not yet obtain numbering of adjusting the distance is numbered, numbering ID adds 1 successively based on the numbering of N+x bracket controller, namely the numbering of this x website be followed successively by N+x+1 ..., N+2x (is understandable that, when preset numbers Cahn-Ingold-Prelog sequence rule is for successively decreasing, be then N-x-1 ..., N-2x).Concrete method for numbering serial is consistent with the method for numbering serial of N main station controller, and the so far numbering work of N+x (when preset numbers Cahn-Ingold-Prelog sequence rule is for successively decreasing, being then N-x) number main website completes.
Based on master-salve station determination mode similar as above, N+2x is (when preset numbers Cahn-Ingold-Prelog sequence rule is for successively decreasing, then for N-2x) number bracket controller is automatic after obtaining numbering becomes main website by slave station, and adopt mode similar to the above, oneself website that is nearest, that do not obtain numbering of adjusting the distance is numbered, No. ID be followed successively by N+2x+1 ... N+3x (is understandable that, when preset numbers Cahn-Ingold-Prelog sequence rule is for successively decreasing, be then N-2x-1 ..., N-3x).
And so forth, the website that the next one becomes main website continues to be numbered all the other unnumbered websites, method for numbering serial is with main website method for numbering serial is consistent before, circulate always, until all websites in system have all been numbered, after having numbered as shown in Fig. 3 (number order for increasing progressively, x=5).In System Number process, all slave stations successfully obtaining ID numbering enter normal operating conditions at once, and the main website after completing all the other site number enters normal operating conditions at once.
Wherein, in numbering process, each main station controller, after having numbered the slave station in its coverage, is also based upon the numbering that its slave station provides, and judges whether System Number completes.
Wherein in a kind of mode, for main website N+kx, based on as mentioned above, its numbering arranged for the slave station in its coverage should be N+kx+1, N+ (k+1) x, be N+ (k+1) x with its distance slave station farthest, the numbering of all slave stations in its coverage and above-mentioned initial number N can be compared by main website N+kx, whether the difference of both judgements equals above-mentioned number M, if, then think that all bracket controllers obtain numbering, System Number completes, otherwise, bracket controller N+ (k+1) x will become main website automatically, continue to perform follow-up process.
In a further mode of operation, for above-mentioned main website N+kx, it after becoming main website, can search the website not obtaining numbering in oneself coverage, if searched less than the website not obtaining numbering, then can think that System Number completes.
In a further mode of operation, for main website N+kx, it can after becoming main website, and it after becoming main website, can search the website not obtaining numbering in oneself coverage.Whether if the number not obtaining the website of numbering searched is not less than preset number x, then a nearest x website of directly adjusting the distance is numbered, do not complete System Number and analyze.If the number not obtaining the website of numbering searched is less than x, then after the site number not obtaining numbering searched is completed, adopt and mode similar in above-mentioned first kind of way, the numbering of distance slave station farthest and above-mentioned initial number N are compared, whether the difference of both judgements is consistent with above-mentioned number M, if consistent, then think that System Number completes.On the other hand, be less than x at the number not obtaining the website of numbering searched, also can directly think that System Number completes.
After System Number completes, whether accurately can also analyze System Number, specifically can by judging that the bracket controller quantity of numbering is analyzed with whether set number of holders M is consistent, if do not met, then send warning message, if met, then illustrate that coding is normal, performs normal workflow.
Actual comparison of coherence can adopt various possible mode to carry out, wherein in a kind of mode, can be when main website decision-making system has been numbered, the numbering of distance slave station farthest and above-mentioned initial number N are compared, whether the difference of both judgements is consistent with above-mentioned number M, and judges that whether System Number is wrong based on consistency checking result.
The bracket controller entering normal operating conditions can carry out normal communication with the adjacent bracket controller in left and right, by judging that numbering determines the adjacent controller in the left and right of oneself, when communication in a data frame with self numbering and object numbering, remaining stents controller after receiving the data, judge whether object numbering numbers consistent with self, consistent then receive, inconsistent, abandon data.
After numbering completes, the bracket controller N as server regularly can send heartbeat packet to whole system, and monitors the system failure based on the feedback of heartbeat packet, if broken down, then carries out alarm.
In addition, in system operation, each bracket controller as main website can also monitor the duty of a preset number bracket controller of self numbering, namely x-1 the slave station oneself covered and next main website, and any one in a preset number bracket controller of self numbering is when breaking down, send warning message, be convenient to carry out Breakdown Maintenance.
In addition, each bracket controller as main website can also every predetermined amount of time, detect a preset number bracket controller and the distance between self of self numbering, namely x-1 the slave station oneself covered and next main website, the distance detected is sorted, and judge whether this sequence mates with the numbering of the above-mentioned preset number of self a numbering bracket controller, if do not mate, then according to distance order from the near to the remote, self numbering above-mentioned, preset numbers order, to in self coverage, numbering is re-started with self nearest preset number bracket controller.Thus if changed bracket controller or some bracket controller falls random order, main website can detect exception, and the website covered oneself renumbers at once.
Based on the thought identical with said method, the embodiment of the present invention also provides the wireless from numbering device of a kind of hydraulic support electrohydraulic control system.The structural representation of this device in an embodiment has been shown in Fig. 5.
As shown in Figure 5, the wireless of the hydraulic support electrohydraulic control system in the present embodiment comprises from numbering device:
Master-slave sta-tion mode handover module 501, for when obtaining self numbering, judging whether self is main website according to self numbering described, default master-salve station decision rule, and being set to main website or slave station according to judged result through mode of operation;
Cover slave station determination module 502, for when the result of determination of described Master-slave sta-tion mode handover module 501 is main website, search the bracket controller not obtaining numbering in self coverage, and connect with the bracket controller not obtaining numbering searched, obtain the distance between self and the bracket controller respectively not obtaining numbering; To determine not obtain in the bracket controller of numbering, with self nearest preset number bracket controller;
Numbering module 503, for according to distance order from the near to the remote, described self numbering, preset numbers Cahn-Ingold-Prelog sequence rule, in the bracket controller not obtaining numbering and self nearest preset number bracket controller be numbered.
According to the scheme of the embodiment of the present invention as above, it is after bracket controller obtains numbering, if it is main website, can connect by other bracket controllers not yet obtaining numbering automatically and in its coverage, and these websites are numbered, based on self numbering of default master-salve station decision rule and acquisition, relevant bracket controller becomes main website automatically, circulation like this, achieve the automatic numbering to bracket controller, without the need to manually arranging bracket controller one by one, decreasing installation workload, reducing the probability of numbering and makeing mistakes.
When implementing the scheme of the embodiment of the present invention, the inside of the bracket controller of each hydraulic support is all built-in with wireless device, this wireless device has normal radio communication function, and can be adopt any possible communication to carry out radio communication, distance between bracket controller and current brackets controller, also can adopt and anyly can determine that the mode of distance is determined.
It should be noted that, because hydraulic support is used in the fully-mechanized mining working in colliery, therefore, when determining the distance between bracket controller and current brackets controller, the conventional localization methods such as GPS (GlobalPositioningSystem, global positioning system) can not be used to determine.
Therefore, in an embody rule example, this wireless device can be the radio communication device based on UWB (UltraWideband is a kind of carrierfree communication technology), is namely communicated by UWB between each bracket controller.UWB can realize the message transmission rate of hundreds of Mbit/s to number Gbit/s in the scope of about 10 meters, there is strong anti-interference performance, transfer rate is high, very bandwidth is wide, consume the many advantages such as electric energy is little, transmitted power is little, thus can make, between bracket controller, there is higher communication performance.The more important thing is, UWB can realize accurate geographic location, possesses the function of range finding, thus by just can realize radio communication and these two functions of finding range at the built-in radio communication device based on UWB of bracket controller simultaneously.
In a concrete example, as shown in Figure 5, the device in the present embodiment can also comprise alarm module 504, now:
Above-mentioned covering slave station determination module 502, also for judging the preset number nearest with self bracket controller and self distance whether within the scope of corresponding predeterminable range;
Above-mentioned alarm module 504, for when the result of determination of covering slave station determination module 502 is no, sends warning information;
Above-mentioned numbering module 503 is when the result of determination of above-mentioned covering slave station determination module 502 is for being, in the bracket controller not obtaining numbering and self nearest preset number bracket controller be numbered.
In the case, by the distance between each bracket controller being in a specific preset range, (namely any main frame is not more than corresponding predeterminable range scope with each distance between machine in its coverage, such as be not more than a corresponding predeterminable range scope with nearest one from the distance of machine, another corresponding predeterminable range scope is not more than from the distance of machine with nearest second, other are by that analogy)), can so that reasonably arrange the distance of each hydraulic support, be conducive to main website to each control from machine in its coverage.When adopting the radio communication device based on UWB, can also guarantee and play the advantage of the communication performance of UWB further.
Wherein, above-mentioned default master-salve station decision rule, based on different Considerations, can set in different ways.
