The resistance sensor read device comprises a character wheel shaft and a plurality of character wheels arranged on the character wheel shaft, ten numbers including 0 to 9 are distributed on the top surface of each character wheel, and each number occupies a reading-out angle; and the resistance sensor read device is characterized in that resistance sensors are arranged on the inner sides of the character wheels. In the resistance sensor read device provided by the utility model, the resistance sensors are additionally arranged on the character wheels; when a rotary disc of the electromagnetic counter rotates, a sensor signal is output by an external pressing sheet; the external microcomputer can acquire the rotation angle within 360 degrees of the rotary disc according to resistance analog quantity output by the resistance sensors and a count value of the rotary disc according to corresponding rotation position of the rotary disc, and is accurate and reliable in reading out; and elastic connection between the external pressing sheet and the resistance sensors can ensure that elastic overload sheets are in reliable contact connection with the external pressing sheet and the resistance sensors when the character wheels rotate, and the interference of a connection wire in the character wheels is avoided.
Description
Technical field
The utility model relates to counter, especially a kind of electric resistance sensor reading device of message register.
Background technology
The character wheel of common mechanical counter does not have sensor signal and digital interface output; Being not easy to microcomputer reads; And, there is increasing application scenario to need the numeral on the reading mechanical counter rotating disk, like the lightning counting device on the lightning arrester JCQ monitor along with the application popularization of present microsystem; Because the needs of electric power online monitoring technology development; On-line monitoring system need read counting thunder, and present lightning counting device can only the manual read fetch data, and does not have sensor or digital signal can export to microcomputer.
Summary of the invention
The purpose of the utility model is the electric resistance sensor reading device that a kind of message register is provided for the deficiency that solves above-mentioned prior art, and on the basis that the manual read fetches data, integrated sensor can convert data message to analog quantity and read for microcomputer.
In order to achieve the above object; The electric resistance sensor reading device of a kind of message register that the utility model designed; Comprise a print wheel shaft and be arranged on a plurality of character wheels on the print wheel shaft; Distributing on the end face of each character wheel respectively occupies ten numerals of 0-9 of a reading angle, it is characterized in that described character wheel inboard is equipped with electric resistance sensor.Electric resistance sensor can be provided with the contact and directly or indirectly link to each other with microcomputer; Along with character wheel rotates; Electric resistance sensor is along with rotation; The resistance that the contact connects changes, and microcomputer is learnt the rotational angle position of character wheel in 360 degree gamuts according to the resistance simulation amount of sensor output, learns the numerical value of counter again according to the correspondence position that rotates.Mechanical counter simply reequiped just can reach become analog quantity for the function that microcomputer reads data-switching, be suitable for large range promotion use.
Improve and replenish as the further of said structure, the utility model also comprises the combination in any of following additional technical feature or these characteristics:
Described electric resistance sensor conflict connects a plurality of elasticity and crosses slide glass; Described elasticity is crossed the slide glass other end and is fixed on the outer compressing tablet; Microcomputer can obtain data message through connecting outer compressing tablet; The interference of having avoided connecting line that character wheel is rotated, and elasticity crosses the vibrations that slide glass can weaken counter, guarantees that the connection of contact point was reliable when character wheel rotated.
Described elasticity is crossed the slide glass two ends and is equipped with a plane and fits with electric resistance sensor and outer compressing tablet respectively, contact reliably, interlude is a bending structure, can carry out the bending of certain angle, plays the effect of elastic shock attenuation.
Each character wheel all connects two elasticity and crosses slide glass, guarantees the reliable and formation loop that connects.
Described electric resistance sensor and character wheel are circle, and electric resistance sensor is arranged in the inboard groove of character wheel, and the location is reliable, rotate the transmission efficiency height.
Described character wheel has three, and described reading angle is 360 degree and is divided equally by ten numerals of 0-9, makes things convenient for reading.
The electric resistance sensor reading device of a kind of message register that the utility model obtains; On the counter character wheel, add resistance type sensor; During the counter dial rotation, through outer compressing tablet output sensor signal, outside microcomputer can be learnt the rotational angle position of rotating disk in 360 ° of gamuts according to the resistance simulation amount of sensor output; Microcomputer is learnt the rotating disk count value according to the correspondence position of dial rotation, and accuracy of reading is reliable; The elasticity of outer compressing tablet and electric resistance sensor is connected, and elasticity is crossed slide glass and is connected reliably with the contact point of outer compressing tablet and electric resistance sensor in the time of can guaranteeing that character wheel rotates, and has avoided the interference of connecting line to the character wheel rotation.
