Abstract
The utility model relates to a passive photoelectric counting sensor of a metering instrument. The technical scheme of the sensor is as follows: transmitting pipes and receiving pipes are arranged at two sides of a character wheel and correspond to one another one by one through code channels on the character wheel; five pairs of transmitting pipes and receiving pipes A, B, C, D and E are arranged in sequence and in different positions; the transmitting pipes A and D are connected with each other, and the pairs of receiving pipes A and D are also connected with each other; and the pairs of transmitting pipes B and E are connected with each other, and the pairs of receiving pipes B and E are connected with each other. The passive photoelectric counting sensor overcomes the defect of error code, namely a mistaken signal is caused as one infrared transmitting pipe irradiates an adjacent infrared receiving pipe which should not be irradiated instead of one opposite infrared receiving pipe. The passive photoelectric counting sensor adopts a plurality of pairs of photoelectric pipes for grouping (pairing) for power supply and transmitting, and one or two pairs of transmitting pipes or receiving pipes are arranged between the transmitting pipes and the receiving pipes in each group at intervals so as to solve the error code problem caused by close distance. The passive photoelectric counting sensor is simple in circuit, and reduces power consumption due to the transmitting of groups by turns.
Description
Technical field
The utility model relates to a kind of passive photoelectricity sensor for countering, especially is applied in the passive photoelectricity sensor for countering of measuring instrument in intellectual water meter, the gas meter, flow meter.
Background technology
Before the present utility model, at present, existing photo-electronic directly reading counter is at other one group of emission and the infrared photocell that receives of installing additional of the mechanical count character wheel of common water meter, gas meter, flow meter, and mechanical reading is transformed into electronical reading.Its principle of work is: the mechanical count character wheel is a roundlet drum type part, cylindrical is printed on 0～90 numeral, it is code channel that the side has hole slot, 0～90 digital co-ordinate position and code channel coordinate angle form one-to-one relationship, and emission and the infrared photocell that receives shine penetrates that the character wheel side leads to or obstructed code channel forms the encode code function of reading of realization electrical equipment of corresponding electric signal; Mechanical character wheel rotates, and guarantee that electrical equipment reads sign indicating number and have reliable redundancy, each numeral that coding should be arranged more than 3, and promptly 0～90 numeral must have coding more than 30, is equivalent to have at least the photoelectric tube more than 5 pairs---and 2
5Individual coding just can meet the demands.Because the mechanical character wheel physical dimension is very little, so 5 pairs of photoelectric tubes can only closely be the fan-shaped character wheel side that is arranged in.When infrared photocell is switched on work simultaneously, because each leans on closely to infrared photocell, can shine adjacent the infrared receiving tube that should not shine during the infrared receiving tube in an infrared transmitting tube irradiation opposite, forming wrong signal is error code.
Summary of the invention
The purpose of this utility model will overcome above-mentioned defective exactly, design, the passive photoelectricity sensor for countering of a kind of measuring instrument of development.
The technical solution of the utility model is:
The passive photoelectricity sensor for countering of measuring instrument, power valve and receiving tube branch are listed in character wheel both sides and corresponding one by one by the code channel on the character wheel, its major technique is characterised in that power valve and receiving tube all have A, B, C, D, E5 right, arrange successively, and be in the diverse location place, two pairs of power valves of A, D are connected, receiving tube also is connected, and two pairs of power valves of B, E are connected, receiving tube also is connected.
Advantage of the present utility model and effect be with on the mechanical count character wheel many to photoelectric tube grouping (to) the power supply emission, and be separated by a pair of between each power valve and the receiving tube in every group or the two pairs of power valves and receiving tube, it is distant to make it distance, and then each is organized group number merging read sign indicating number, thereby solved between the photo-electronic directly reading counter because of the close error code problem that causes of distance.
Simple and each group emission in turn of the utility model circuit has reduced power consumption.
Other advantages of the utility model and effect will go on to say below.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.

Embodiment
As shown in Figure 1 and Figure 2:
During the utility model work:
This method adjacent light fulgurite mistake can not occur according to misreading when reading yard, and the grouping power-on circuit is low in energy consumption, life of product is long.
The utility model scope of asking for protection is not limited to embodiment explanation of the present utility model, also is not limited to 5 pairs of power valves 1 and receiving tube 3, can be applied to the situation of a plurality of power valves 1 and receiving tube 3 according to innovative thinking of the present utility model.
