The embodiment of the invention discloses a kind of communication means based on parameter negotiation, Apparatus and system, effectively can overcome intersymbol interference, strengthen the stability of communication link, and elevator system reliability.Below describe in detail respectively.
Referring to Fig. 3, is the schematic flow sheet of a kind of communication means based on parameter negotiation that the embodiment of the present invention provides, and concrete, as shown in Figure 3, the described method of the embodiment of the present invention can comprise the following steps:
S101: the first communication equipment is held consultation to target component according to default negotiation algorithm, and the targeted parameter value obtained after obtaining described negotiation, wherein, the channel bit error rate that described targeted parameter value is corresponding is less than default bit error rate threshold.
It should be noted that, the described method of the embodiment of the present invention can be applied particularly in digital communication system, and can perform in the first communication equipment specifically in this digital communication system, and wherein, this first communication equipment is transmitter or receiver.
In specific embodiment, a bit error rate threshold can be pre-determined according to the actual requirements.Such as, because the link negotiation time is shorter, adaptive equalization technique generally adopts higher than code requirement, and the channel bit error rate as current code requirement is 10 -12bit/s (bits per second), then can according to higher than this 10 -12the channel bit error rate of bit/s is as 10 -7the parameter of bit/s to communication equipment is held consultation.
Concrete, when default negotiation algorithm is held consultation to target component, the first communication equipment first forward adjustment can increase the weight of parameter, if the error rate becomes large, then oppositely adjusts parameter, otherwise continues forward adjustment parameter, until when the error rate is less than 10 -7during bit/s, the targeted parameter value (namely consulting rear) after the first communication equipment can acquire this adjustment.
S102: described first communication equipment judges whether described targeted parameter value is within the scope of the preset parameter region corresponding with described target component.
In specific embodiment, due to the transmitter parameter of at every turn consulting and receiver parameters more concentrated, the link set up based on this parameter is more stable, and the reliability eliminating ISI is also higher.Therefore, can in advance for target component configuration obtain a parameter region, this parameter region indicates the target component of better span, the parameter value that the zone line comparatively concentrated as parameter distribution in Fig. 1 is corresponding.
Optionally, this parameter region can be that insertion loss (InsertLoss is called for short " IL ") information according to the transmission channel between the transmitter that detects and receiver is determined.Then this first communication equipment is also by obtaining the insertion loss information of transmission channel between described second communication equipment, thus with the described insertion loss information obtained for foundation, presetly obtains the parameter region corresponding with described target component.
Further alternative, this parameter region can be determine according to the working temperature under the network operational environment detected.Then this first communication equipment is also by obtaining the working temperature under operational environment residing for described first communication equipment, and with temperature range corresponding to the described working temperature got for foundation, presetly obtains the parameter region corresponding with described target component.
After targeted parameter value after acquiring this negotiation, whether value and the targeted parameter value that can detect the target component that this negotiation obtains are within the scope of parameter region corresponding to this target component.If be within the scope of this parameter region, when namely judged result is for being, consults to terminate, and can step S103 be performed; Otherwise, can step S101 be performed, repeat this negotiations process, until the new targeted parameter value negotiated is within the scope of this parameter region.
S103: if be within the scope of described parameter region, then described first communication equipment sets up communication link based on described targeted parameter value and second communication equipment, and is communicated with described second communication equipment by described communication link.
In specific embodiment, obtain being in the targeted parameter value within the scope of parameter region corresponding to this target component in negotiation, namely during better parameter value, namely link is set up by this targeted parameter value negotiated and second communication equipment, and communicate based on the link of this foundation, thus overcome intersymbol interference, and promote the stability of communication link.Wherein, this second communication equipment is corresponding with the current equipment carrying out parameter negotiation, and also, the first communication equipment carrying out parameter negotiation if current is the transmitter in digital communication system, and namely this second communication equipment is the receiver in this digital communication system; Corresponding, the first communication equipment carrying out parameter negotiation if current is the receiver in digital communication system, and namely this second communication equipment is the transmitter in this digital communication system.
Further alternative, before described first communication equipment to be held consultation to target component according to default negotiation algorithm, described first communication equipment also can detect the enable current state of preset negotiation, and described current state comprises opening or closed condition; If described negotiation is enable be in opening, then according to default negotiation algorithm, target component is held consultation described in described first communication equipment execution, and the step of the targeted parameter value obtained after obtaining described negotiation; If described negotiation is enable be in closed condition, then described first communication equipment obtains the preset parameter setting values corresponding with described target component, and using described parameter setting values as targeted parameter value.That is, can the enable switch of a pre-configured consultation parameter, and a preset parameter setting values corresponding with this target component, thus in this enable switch of unlatching, namely consult enable when being in opening, the negotiation algorithm that the first communication equipment triggers according to presetting carries out parameter negotiation and obtains the flow process of targeted parameter value; Otherwise then this first communication equipment directly calls that this is preset with this parameter setting values, and using this parameter setting values as this targeted parameter value, to communicate with second communication equipment based on this targeted parameter value and parameter setting values.
Further, need the parameter of consulting may comprise multiple, then can be respectively preset parameter parameter region that each needs to consult, carry out parameter negotiation with the parameter region based on each correspondence.Concrete, can the parameter of consulting be needed as target component each, according to default negotiation algorithm, this target component is held consultation, the targeted parameter value obtained after obtaining described negotiation, and judge whether described targeted parameter value is within the scope of the preset parameter region corresponding with described target component; When the corresponding targeted parameter value of multiple target component needing to consult all is within the scope of each self-corresponding parameter region, then this first communication equipment can set up communication link based on the multiple targeted parameter value be within the scope of each self-corresponding parameter region and second communication equipment, and is communicated with described second communication equipment by described communication link.Wherein, if this first communication equipment is transmitter, then need the parameter of holding consultation can comprise the parameter such as postemphasis (being generally designated as C1), amplitude (being generally designated as C0), preshoot (being generally designated as C3) of transmitter; If this first communication equipment is receiver, then need the parameter of holding consultation can comprise the parameter such as gain (being generally designated as GAIN), penalty coefficient (ADC), linear feedback parameter (being generally designated as DFE0, DFE1 etc.) of receiver.Optionally, this default negotiation algorithm can be the fixing algorithm being solidificated in inside communication equipment, also can be the negotiation algorithm for holding consultation within the scope of this parameter region generated according to the parameter region of this setting.
Further alternative, when described targeted parameter value is not within the scope of described parameter region, described first communication equipment can control to repeat describedly holds consultation to target component according to default negotiation algorithm, and the targeted parameter value obtained after obtaining described negotiation, and judge whether described targeted parameter value is in the step within the scope of the preset parameter region corresponding with described target component, i.e. repeated execution of steps S101 to S102; And record the negotiation number of times of described negotiation; Whether the described negotiation number of times of described first communication equipment detection record exceedes setting threshold; If exceed described setting threshold, then described first communication equipment sends alarm.Wherein, this setting threshold can pre-set and obtain, and is such as set to 5 times, then the first communication equipment can carry out alarm after repeating 5 subparameters and consulting, so that notify relevant device, it is abnormal.
In embodiments of the present invention, can hold consultation to needing the target component of consulting according to the negotiation algorithm preset, negotiation obtains the targeted parameter value that channel bit error rate is less than default bit error rate threshold, and whether be in preset with corresponding parameter region that is this target component by detecting the targeted parameter value that obtains of this negotiation, determine that negotiation completes when this targeted parameter value is within the scope of this parameter region, set up communication link with the targeted parameter value negotiated based on this with second communication equipment to communicate, thus can effectively overcome because fading channel etc. affects the intersymbol interference brought, make the stability enhancing communication link, and improve system reliability.
Referring to Fig. 4, is the structural representation of a kind of communication system based on parameter negotiation that the embodiment of the present invention provides, and concrete, as shown in Figure 4, the described system of the embodiment of the present invention can comprise: transmitter 1 and receiver 2; Wherein,
