Description
Technical field
The invention belongs to block terminal power supply ordering techniques field, more particularly to a kind of sensor-based system electricity based on positional information
Source collator and its method, multiple sensor assemblies, circuit or function group for managing an annular or arc systems
Power supply sorts.
Background technology
Traditional power supply sort method is come by the delay of independent circuits hardware or software programming delay of each detector
Realize.
One of common hardware time-delay method is to be directly proportional using one or more RC circuits to generate to its charging interval
Delay.It is not co-extensive so as to produce that potentiometer can realize different RC constants for individually adjusting the resistance value of each module
When.This method can only provide limited time delay scope, therefore not be suitable for the system with a large amount of detector modules.Separately
Outside, assembled for large scale system also very poorly efficient.Common hardware another method that is delayed is to set number using many code switches
Word delay coding.The method equally exists the shortcoming of inefficient system assembling, and needs reserved larger mechanical box or circuit
Plate space is to facilitate hand-coding.
Distinguish as software programming time-delay method usually using central a timing control unit and multichannel communication circuit
Each detector module is connected to realize.Delay is by control unit when detector is manufactured（Pre-programmed）Or after system assembles（Afterwards
Programming）Set.This method not only needs to use the part and complicated communication line of costliness, and system assembling is also required to increase
Plus the additional step of delay programming.
The common drawback of existing two methods described above is each detector needs in hardware setting or software
It is handled differently to realize different start-up studies, it is necessary to function support part costly and efficiency of assembling is low in programming
Under.On the other hand, all also there are common potential problems in above two existing method, after system assembles or fielded system
If it is desired to change existing delay duration or clooating sequence after maintenance, it usually needs hardware " is reprogramed ".In some cases, very
Realized to needing to disassemble and recombinate by presence detector.
On the other hand, in many medical treatment and industrial diagnostics application, in order to realize detection homogeneity, usually using annular or
The detector assembling structure of arc.Typical sensor-based system is typically made up of the detector of multiple arrays, in most cases, each
Detector array needs independent support circuit and specific mechanical support structure, and they are collectively forming a detector module.
In similar application, it by single power supply is multiple module for power supply that typical system power supply mode, which is, and utilizes power supply sequencing
Device controls to realize that power supply sorts, and power supply sequence contributes to control high surge current and limitation above electric noise.
Although power supply ranking function has been realized in extensive application in itself, pass through integrated circuit（IC）Or set up multichannel
The increased system cost of method institute of communication is very undesirable.Further, since the need for pre-programmed or rear programming, traditional sort method
Extra installation step is needed, and tends to error.
Therefore, prior art is further improved and perfect.
