The invention discloses a kind of digital sensors, which is characterized in that by M old digital sensors, dismantling easily counts sensor and an external data integrator at M.M easily count amplifier, A/D chip, the CPU that sensor retains old digital sensor, and pressure stabilizing and communication chip are placed on external data integrator.M-1 voltage stabilizing chip and M-1 communication chip are saved, an outer CPU is increased.It is grown up to be a useful person and is formed by the data set of N number of easy several sensors and an outside, N >=1, data integration device have M data-in port, and N number of data-in port in M data-in port is separately connected N number of easy several sensors, M >=N, data set, which is grown up to be a useful person, to be connect with N number of easy several sensors using separate hardware.The present invention solves the trouble that former digital sensor is at high cost, volume is big, communication speed is slow and address is arranged, and also substantially increases communication reliability.
Description
Technical field
The present invention relates to it is a kind of it is at low cost, communication speed is high, zero-address digital sensor.
Background technique
Existing digital sensor as shown in Figure 1, sensor internal be integrated with amplifier, A/D chip, microprocessor CPU,
Voltage stabilizing chip, communication chip etc..In multiple digital sensor application occasion, external equipment passes through bus mode and number shown in FIG. 1
Word sensor communication, so digital sensor must be provided with address.When old digital sensor needs repairing, it is necessary to will newly count
Identical address is arranged in word sensor, could replace old digital sensor.
And in conjunction with Fig. 2, the bus communication mode of external equipment and existing digital sensor is communicated using response formula, is needed
Each numeric sensor data is read one by one, and speed is slower.If one of digital sensor communication failure (short circuit), will
Cause whole bus that cannot communicate.
Summary of the invention
Object of the present invention is to: increase the reliability of flexibility and the communication of digital sensor and reduces cost.
In order to achieve the above object, the technical solution of the present invention is to provide a kind of digital sensors, which is characterized in that will
M old digital sensors, dismantling easily count sensor and an external data integrator at M.M easily number sensor reservations are old
There are amplifier, A/D chip, the CPU of digital sensor, pressure stabilizing and communication chip are placed on external data integrator.Save M-
1 voltage stabilizing chip and M-1 communication chip increase an outer CPU.By N number of easy several sensors and the data set of an outside
It grows up to be a useful person composition, N >=1, data integration device has M data-in port, N number of data input pin in M data-in port
Mouth is separately connected N number of easy several sensors, M >=N, and data set, which is grown up to be a useful person, to be connect with N number of easy several sensors using separate hardware, in which:
Each easily number sensor is made of amplifier, A/D chip, microprocessor CPU, and external analog signal accesses amplification
Device, amplifier are connected with the input end of analog signal of A/D chip, and the digital signal output end of A/D chip connects one CPU of microprocessor
Data input pin, the corresponding data-in port that the data output end of one CPU of microprocessor and data set are grown up to be a useful person is connected；
Data set is grown up to be a useful person to be made of voltage stabilizing chip, communication chip and two CPU of microprocessor, voltage stabilizing chip be communication chip,
Two CPU of microprocessor and N number of easy several sensors provide operating voltage, and the data input pin of two CPU of microprocessor and M data are defeated
Inbound port is connected, the data output end connecting communication chip of two CPU of microprocessor, and communication chip is established data with external equipment and led to
News.
Preferably, the communication chip establishes the data communication by bus with the external equipment.
Preferably, two CPU of microprocessor will pass through again institute after the data summarization received from N number of easy several sensors
It states communication chip and is sent to the external equipment.
In the present invention, data set, which is grown up to be a useful person, to be connect with easily several sensors using separate hardware, so data transmission bauds is high, end
Slogan is exactly sensor number, very easy to use without address.Meanwhile because data integrator and easily number sensor are using independent
Hardware connection will not influence other easy several working sensors so one easily counts sensor fault, communicate more reliable.More into one
Step, data set are grown up to be a useful person after the data summarization of each easy several sensors, then with peripheral device communication, so communication speed of the invention
It is high.Due to eliminating M-1 voltage stabilizing chip and M-1 communication chip, so cost sharp fall.The present invention solves former number
Word sensor is at high cost, volume is big, communication speed is slow and the trouble of setting address, also substantially increases communication reliability.
Detailed description of the invention
Fig. 1 is the circuit block diagram of existing digital sensor；
Fig. 2 is the communication flow figure of existing digital sensor；
Fig. 3 is the circuit block diagram of digital sensor provided by the invention；
Fig. 4 is the communication flow figure of digital sensor provided by the invention.
Specific embodiment
Present invention will be further explained below with reference to specific examples.It should be understood that these embodiments are merely to illustrate the present invention
Rather than it limits the scope of the invention.In addition, it should also be understood that, after reading the content taught by the present invention, those skilled in the art
Member can make various changes or modifications the present invention, and such equivalent forms equally fall within the application the appended claims and limited
Range.
Original digital sensor is resolved into two parts by the present invention: amplifier, AD core in existing digital sensor
Piece and microprocessor CPU constitute an easily number sensor；Voltage stabilizing chip and communication core in existing digital sensor
Piece is further added by a microprocessor CPU and constitutes external data set and grows up to be a useful person.Therefore, the present invention in easy several sensors significantly
Reduce the circuit of sensor internal, volume be can be made smaller.
As shown in figure 3, in the present embodiment, n easily number sensors are separately connected data set and grow up to be a useful person n data input pin of moral
Mouthful, data set is grown up to be a useful person uses separate hardware to connect with n easily number sensors, in which:
Each easily number sensor is made of amplifier, A/D chip, one CPU of microprocessor, and external analog signal access is put
Big device, amplifier are connected with the input end of analog signal of A/D chip, and the digital signal output end of A/D chip connects microprocessor one
The data input pin of CPU, the corresponding data-in port phase that the data output end of one CPU of microprocessor is grown up to be a useful person with data set
Even；
Data set is grown up to be a useful person to be made of voltage stabilizing chip, communication chip and two CPU of microprocessor, voltage stabilizing chip be communication chip,
Two CPU of microprocessor and N number of easy several sensors provide operating voltage, and the data input pin of two CPU of microprocessor and M data are defeated
