Abstract
The utility model relates to a remote transmitting electronic reading water meter. In the utility model, one side of a drive gear of indicating needle of the water meter is in parallel provided with two non-interfering sensors, and the indicating needle of the water meter is inlaid with magnet steel. The magnetic steel on the drive gear of the indicating needle of the water meter is respectively sensed with the sensors positioned at different positions to send out pulse signals at the time of rotation, and the pulse signals can be transmitted to an after reading device; thus, an effective counting cycle is obtained; so the case of the repetition count caused by the dithering of the sensors when the magnetic steel and the sensor are positioned at the relative critical position can be avoided. The utility model has the advantages that the reliability and the accuracy of the electric remote transmitting numerical reading can be achieved, and the real-time detection of interference and the failure of a transmission line can be realized simultaneously.
Description
The utility model relates to the architecture advances of measuring instrument, especially a kind of teletransmission electronical reading metering water meter.
Traditional metering water meter is by the series of gears gear that is provided with in it flow to be converted to the number that can Gong read, and it is simple in structure, accurate measurement is reliable.For making things convenient for the stoichiometric number of supvr's water-meter reading, Chinese patent ZL95212638.9 discloses a kind of " electrical distance transmitting meter reading device ", its structure is to set up " electrical distance transmitting electronic package " on the gear of traditional metering water meter, can will convert to and can conveniently read for the supvr by this electrical distance transmitting assembly with the proportional gear rotational speed of flow for the electric impulse signal of computer interface.Its design concept is to being arranged on the magnet steel induction on the metering water meter gear by sensor, sending electric impulse signal supplies to read in machine processing back as calculated, and when in fact the magnet steel on being set in the water meter gear and sensor are on mechanical critical localisation, irregular chatterin will take place and cause the subsequent treatment mistake in sensor, cause repeat count, thereby cause the remote meter reading metering inaccurate.
The purpose of this utility model is the deficiency that exists at above-mentioned teletransmission electrometer water gauge, provide a kind of can solve when be set in magnet steel on the water meter gear and sensor on mechanical critical localisation irregular action and cause electric pulse to count an inaccurate difficult problem; Simultaneously, can realize to artificial malicious interference and electrical signal transmission line road open circuit, the teletransmission electronical reading metering water meter of the Realtime Alerts of short circuit.
Teletransmission electronical reading metering water meter of the present utility model is realized by following design proposal: the indicator of water gauge transmission gear that studs with magnet steel etc. radial location one side two the non-interfering sensors that be arranged in parallel.The magnet steel that the gear driven that utilizes water meter to rotate is set on the gear periphery rotates simultaneously, be arranged on two sensors induction action respectively under the magnet steel magneticaction that changes of this gear below, make the magnet steel in the rotation send pulse signal with being in the sensor in different positions induction respectively, and as an effective count cycle.Thereby avoided magnet steel and sensor when relative critical localisation, shake takes place and causes repeat count in sensor; Because geographically actual range is very near for two sensors being adopted, disturb responsive to external world and action simultaneously gets final product real-time confirmation; Simultaneously can effectively detect opening circuit and short trouble of electrical signal transmission line road.
The good effect that teletransmission electronical reading metering water meter of the present utility model is produced is: realized the electrical distance transmitting reliable reading of metering water meter, accurately, realizing the fault detecting real-time to interference and transmission line simultaneously, is a kind of reliable, economic, practical teletransmission electronical reading metering water meter.
The concrete structure of teletransmission electronical reading metering water meter of the present utility model is provided in detail by the following drawings and embodiment.
Fig. 1 is the structural representation of teletransmission electronical reading metering water meter;
Fig. 2 is the sensor circuit schematic diagram of teletransmission electronical reading metering water meter.
Embodiment: identical with existing metering water meter from the dial train gear shift of the visible teletransmission electronical reading of Fig. 1 metering water meter, transmission gear 2 edges of indicator of water gauge 1 edge is put a magnet steel 3, radial location such as the below of transmission gear 2 and gear shaft two sensors 4,5 that be arranged in parallel.The circuit theory of sensor 4,5 is seen Fig. 2, the pulse signal sensing circuit by parallel resistor R1, R2, R3 and be connected in respectively R2, R3 the end sensor 4,5 constitute.Its course of work is: when magnet steel 3 acts on sensor 4 and sensor 5 respectively with gear 2 rotations, just can obtain different equivalent resistances at the two ends of signal transmission line L1, L2, it is a count cycle that two sensors 4,5 respond respectively successively, and these pulse signals promptly are reliable metrical informations through subsequent treatment.When the magnet steel 3 in the rotation is in the critical localisation of sensor 4 actions, the aftertreatment device of remote transmitting water meter will not be admitted the shake action message of sensor 4 before the information that does not obtain sensor 5 actions, and vice versa.When outer interference cause two sensors 4,5 to move simultaneously or signal transmission line opens circuit, during short circuit, the equivalent resistance that L1, L2 end is reflected also has nothing in common with each other, thereby provides reliable basis for estimation for detecting these phenomenons.Therefore, the utility model information that can verily the water meter gear be rotated a circle fully be sent to water meter after read treating apparatus; When strong magnetic being set,, can conclude outer magnetic interference in view of the above because the water meter diameter much larger than two sensors, 4,5 spacings, must cause two sensors 4,5 to move simultaneously at the water meter periphery; Signal transmission line opens circuit, during short circuit, the equivalent resistance that L1, L2 end is reflected also has nothing in common with each other, thereby provides reliable basis for estimation for detecting these phenomenons.
