Description
The present invention relates to a kind of device that analog quantity is carried out digitized processing.
The existing mode that analog quantity is carried out digitized processing mainly contains three kinds:
1.A/D transformation circuit method: change analog quantity into voltage or current signal earlier, again this signal is transformed into digital quantity immediately with the A/D change-over circuit, receive and record with computing machine again.Because this conversion is real-time, just can not work in case have a power failure, and have many equipment when having a power failure still in normal use, as water meter, gas meter etc., to these equipment if carry out digitized processing with said method, will bring gross error, after restoring electricity, could operate as normal after need proofreading and correct the data of record.
2. rotating disk compiling method: with analog quantity through gear drive, the anglec of rotation that becomes the coding rotary disk continous way changes, on card perpendicular to rotating shaft, ecto-entad be furnished with a few by low level to coding circle high-order, that form by " 0 " " 1 " digital marking, transducer arrangements is in the side of code-wheel, each coding circle only has a sensor corresponding with it, and sensor can outwards provide the numerical coding of the current angle value of code-wheel during use, receives and record with computing machine again.According to said method She Ji scrambler has: the SZGM-01 photoelectric encoder.For further improving encoding precision, high, medium and low position is set sometimes waits several code-wheels, the rotation of each code-wheel all is a kind of successional, and just the angle of rotation becomes certain multiple relation, so that can provide the numerical value of each section of high, medium and low position in the binary number after the digitizing.She Ji scrambler has in this way: BMQ-2X contact shaft-position encoder.Need not proofread and correct after this type of compiling method can accomplish to have a power failure and to recover operate as normal, but also there is following point: A. because each sensor is corresponding with a coding circle, therefore encoding precision is directly proportional with the digital marking number of encoding on enclosing, under the certain situation of digital marking size, for keeping certain encoding precision, the diameter of coding circle just must be done greatlyyer, so the volume of class scrambler is also bigger, usually its diameter is between 70～ 170, and the diameter of existing water meter panel is only between 70～ 80, if this type of scrambler is installed in table, volume will increase more than the several times; B. under the diameter and the big or small certain condition of digital marking of coding circle, it is very limited that a coding encloses the digital marking number that can set, and each coding circle only has a sensor corresponding with it, therefore the scope of scrambler output valve is smaller, be mainly used in the angle of rotating shaft is carried out digital coding, so be not suitable for the equipment that ammeter, water meter etc. need carry out digitized processing to the big number of accumulative total.
3. differential code method: analog quantity is resolved into a lot of " base unit values ", when the increase and decrease of " base unit value " takes place in analog quantity, just outwards send a positive pulse or negative pulse, add up by the computing machine paired pulses of outside again, thereby draw currency, " D86-M series " pulsed watt-hour meter of producing as country's typing adopts this mode exactly, the problem that it exists is: because line fault, situations such as power failure can cause partial pulse to be lost, and verification automatically between the digitized record value of the currency of instrument and computing machine, can cause two cover systems " reading " that tangible difference is arranged after the long-time running, need regularly carry out desk checking, when computer network will be monitored thousands of the such watt-hour meter of hundreds of simultaneously, again the workload of Jiao Zhenging is very large, in order to address this problem, people have adopted the whole bag of tricks to improve the reliability of system: complicated computer network, add holding storage battery or the like, although the cost of system is increased greatly, also fails fundamentally to address this problem.
The purpose of this invention is to provide and a kind ofly also cumulative errors can not occur, also do not need device manual synchronizing, that analog quantity carried out digitized processing after the power failure having under the situation of line fault and other random disturbance.
For achieving the above object, the present invention proposes a kind of new digital coding device: it is by the coding wheels, wheel shaft, the carry gear, gear shaft, rotate the input gear, digital marking, wheel support, sensor, the erecting frame of sensor is formed, the coding wheels, rotate the input gear through wheel shaft, the carry gear is installed on the wheel support through gear shaft, analog quantity is taken turns through the low level that rotation input gear passes to earlier in the coding wheels, and the continous way that will rotate the input gear is rotated, the batch (-type) that converts this code wheel to rotates, take turns transmission by the mode of A system to a high position through the carry gear by the low level wheel again, code wheel is provided with M the discernible digital marking of sensor, and the formation coding circle coaxial with code wheel, M is the integral multiple of A, each code wheel is discerned the digital marking of its current location with n sensor, and Integer n should make following formula set up: 2
n＞A, sensor is fixed on the wheel support through erecting frame, the information of sending with the identification number code labeling.
Above-mentioned digital marking can be made by extinction and reflectorized material respectively, sensor is made of light-emitting component and light activated element, when code wheel rotated to desired location, reflectorized material reflected the light that light-emitting component sends to light activated element, and made its action and send digital signal.
Above-mentioned digital marking can be made by permanent magnetic material, sensor is by magneto sensor: tongue tube or mistor or Hall element or magnetic transister constitute, when code wheel rotated to desired location, permanent magnetic material was near magneto sensor, and made its action and send digital signal.
Above-mentioned digital marking can be made by permeability magnetic material, and sensor is made of inductance element, and when code wheel rotated to desired location, permeability magnetic material was near inductance element, and its inductance value is changed and sends digital signal.
