Description
Technical field
The utility model belongs to calibration system technical field, more particularly to a kind of calibration system on sensor.
Background technology
The demarcation operation of the products such as instrument, sensor, the physics corresponding to all external conditions such as zero point and full scale
Condition (pressure, weight, speed ...) is identical, and physical signalling (such as voltage, electric current, the instrument of each sensor output
Indicating value etc.) small difference is had again.Instrument, transducer calibration are wasted time and energy one by one, are unfavorable for product mass operation.And
Modern digital formula sensor, instrument employ singlechip technology mostly, using the single-chip microcomputer of commonsense method burning, all sensings
Device inner parameter (containing address) is identical, when sensor being demarcated and communicated using serial communication, because address is identical
And single sensor can not be made a distinction；Even if the inner parameter of single sensor is there occurs becoming during demarcation, it is not easy to will
It is picked out.Single transducer calibration is wasted time and energy, and is unfavorable for mass operation.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of the prior art, and provides a kind of mark on sensor
Determine system, realize the function of broadcast and point-to- point communication simultaneously to the sensor with identical address, can undoubtedly accelerate operation speed
Degree, uses manpower and material resources sparingly.
The purpose of this utility model is completed by following technical solution, including main frame, control panel, selecting switch,
Described main frame is connected by serial port with control panel, and the control panel is by selecting switch and uses serial communication side
Formula is connected with each sensor；Described control panel is provided with several selection signals, and the selection signal is opened for control selections
Close and corresponded with several sensors, opening and closing for selection signal control selections switch, can be built separately or together
Vertical communication port between main frame and several sensors.
Preferably, the selection signal that is provided with of described control panel controlled by control panel and with several sensors one
One correspondence.
Preferably, described serial port is RS485 modes or RS232 modes or RS422 modes.
The beneficial effects of the utility model are：
1), at the unallocated address of sensor, it is possible to achieve point-to- point communication is that each sensor distributes address by main frame；
2) after, distributing address, each sensor can be proofreaded respectively, directly judges defective work, can be with
Realize main frame to sensor, point-to- point communication function of the sensor to sensor；
3) broadcast capability, can be realized, the common selecting switch of multiselect one can only realize man-to-man communication, it is impossible to simultaneously
All connections are established, this programme can establish the communication channel of all the sensors simultaneously, realize the function of broadcast.
Brief description of the drawings
Fig. 1 is system connection diagram of the present utility model.
Fig. 2 is control panel of the present utility model and sensor connection diagram.
Label in accompanying drawing is respectively：1st, main frame；2nd, control panel；3rd, sensor；4th, selecting switch；21st, TX passages；22、
RX passages；23rd, selection signal.
Embodiment
Detailed introduction is done to the utility model below in conjunction with accompanying drawing：As shown in accompanying drawing 1,2, the utility model includes master
Machine 1, control panel 2, described main frame 1 are connected by serial port with control panel 2, and the control panel 2 passes through serial communication
Mode is connected with sensor 3；There are TX passages 21, RX passages 22 and several selection signals 23 on described control panel 2, wherein
Selection signal 23 is connected with selecting switch 4.Control panel 2 switchs 4 so as to realize control main frame by the control selections of selection signal 23
TX passages 21, (RX001, the TX001 of RX passages 22 and each sensor 3；RX002, TX002；RX003, TX003 ...) passage
Connection.The opening and closing can control main frame 1 and different sensors 3 of different choice signal 23 in selecting switch 4 it
Between communication channel break-make.
Controlled after the command analysis that described selecting switch 4 is issued by control panel 2 according to main frame 1 by selection signal 23
System.
Described serial port is RS485 modes or RS232 modes or RS422 modes.
A kind of scaling method of calibration system on sensor, the scaling method are main frame 1 by under serial communication
Say the word to control panel 2, control panel 2 switchs 4 by the control selections of selection signal 23, selecting switch 4 can select from it is different
Sensor 3 is communicated, and control panel 2 is switched by the control selections of selection signal 23 and opens and close from the sensor 3 of different passages, can
To realize point-to-point or broadcast communication function respectively；So the can of main frame 1 uses the method for poll to divide for each sensor 3
With address, sensor 3 initialization initial stage is avoided, the physical address of all the sensors 3 is identical can not to realize asking for point-to- point communication
Topic.As shown in Figure 2, for example, when main frame and sensor 31 communicate, can transmitting order to lower levels to control panel selector channel 1, corresponding selection
S1 switch closure is switched, other selecting switch (S2, S3 ...) are opened.Now main frame 1, control panel 2, sensor 31 hardware
Connection is established in physical channel (TX and RX001, RX and TX001), and other passages are disconnected, and main frame can be issued individually to sensor 31
The personalizing parameters such as address.
Described main frame 1 is by TX passages 21, RX passages 22 successively to (RX001, TX001 in each sensor 3；RX002,
TX002；RX003, TX003 ...) poll issue address distribution order, when all selection signals 23 for closure when, Suo Youchuan
The physical channel of sensor 3 is all established, and is realized the function of broadcast and to all the sensors 3 while can be demarcated -- extraneous physical condition
When identical, zero point or full scale are specified by ordering.
The utility model is not limited to above-mentioned embodiment, makees any change no matter being formed in its shape or material, all
It is to use structure design provided by the utility model, is all a kind of deformation of the present utility model, is considered as new in this practicality
Within type protection domain.
