Abstract
The utility model relates to a double-frequency cow activity monitor. The monitor comprises identification signal transmitting devices arranged on cow bodies and a plurality of milking unit readers in a milking parlor, wherein each identification signal transmitting device is a low-frequency signal and high-frequency signal transmitting device with an acceleration sensor; each of a plurality of milking unit readers is arranged around the milking position of each crow; a plurality of milking unit readers are connected with a control host through a local area network; and each milking unit reader is provided with a low-frequency signal transmitting and receiving circuit and a high-frequency signal transmitting and receiving circuit. The monitor has the advantages of low-frequency accurate positioning and ultrahigh-frequency remote transmission, greatly improves the crow positioning accuracy and the reliability of activity data, has the advantages of manpower elimination, high accuracy and the like, and is very significant for improving the crow mating success rate, shortening the empty pregnant period, shortening the embryo interval and improving the milk yield.
Description
Technical field
The utility model relates to a kind of double frequency milk cow activity monitor, utilizes the activity monitoring of wearable sensors realization to the milk cow activity on the milk cow health.
Background technology
Breeding is one of important step during dairy is produced.The quality of cow reproduction management not only affects quantity and the quality of cows, and directly affects milk yield, value and the economic benefit of cows.In production practices, periodically carry out in order to keep milk cow breeding, gestation, calving, lactation production process, need the activity of monitoring cow oestrus to determine the best semen deposition time, milk cow is normally become pregnant.Traditional monitoring method of oestrusing mainly relies on the behavior symptom before animal doctor personnel clinical observation cow oestrus, and the method is owing to being limit by personnel's experience level and high workload dense degree, and easy generation is missed the leakage of feelings phase and joined phenomenon, and then affects the cow reproduction process.
Summary of the invention
The purpose of this utility model is to propose a kind of double frequency milk cow activity monitor technical scheme, utilizes the activity monitoring of wearable sensors realization to the milk cow activity on the milk cow health, and then the best semen deposition time of definite cow oestrus.
to achieve these goals, the technical solution of the utility model is: a kind of double frequency milk cow activity monitor, comprise be arranged on ox with it the id signal emitter and a plurality of unit readers of milking in milking parlour, wherein, described id signal emitter is with the low frequency signal of acceleration transducer and high-frequency signal emitter, described a plurality of unit reader of milking is respectively around the cattle pen setting of milking of every a head of cattle, a plurality of identification readers are connected with main control system by LAN, the described unit reader of milking is respectively arranged with low frequency signal transceiver circuit and high-frequency signal transceiver circuit.
Further, in the described unit reader of milking is arranged on and does not exceed the cattle pen scope of a meter apart from ox.
Further, described low frequency signal is 125Khz, and described high-frequency signal is 915Mhz.
Further, be provided with gate inhibition's formula reader in described cattle pen porch, gate inhibition's formula reader is connected with main control system by network.
The beneficial effects of the utility model are: have low frequency accurately advantage and the ultrahigh frequency remote transmission advantage of location, greatly improved the accuracy of milk cow location, and the reliability of activity data, make the entire system performance reach level preferably, effect is very good.Can realize 24 hours to the collection of action messages such as moving, couch, stand, by the oestrus of computer software comprehensive analysis and judgement milk cow; Compare with the tradition monitoring method of oestrusing, the utlity model has round-the-clock uninterrupted monitoring, need not artificial, high accuracy for examination, for improving milk cow breeding success rate, reduce nonpregnant number of days, shorten the tire spacing, improving the milk yield tool and be of great significance.
Below in conjunction with drawings and Examples, the utility model being done one describes in detail.

Fig. 2 the utility model electrical block diagram.
Embodiment
a kind of double frequency milk cow activity monitor embodiment, referring to Fig. 1 and Fig. 2, described monitor comprise be arranged on ox with it id signal emitter 1 and a plurality of unit readers 3 of milking in milking parlour 2, wherein, described id signal emitter is with the low frequency signal of acceleration transducer and high-frequency signal emitter, described a plurality of milk the unit reader respectively around every a head of cattle milk the position 4 cattle pen settings, a plurality of unit readers of milking are connected with main control system 6 by LAN 5, the described unit reader of milking is respectively arranged with low frequency signal transceiver circuit and high-frequency signal transceiver circuit.
In embodiment, in the described unit reader of milking is arranged on and does not exceed the cattle pen scope of 1 meter apart from ox.
In embodiment, described low frequency signal is 125Khz, and described high-frequency signal is 915Mhz.
Further, be provided with gate inhibition's formula reader 7 in described cattle pen porch, gate inhibition's formula reader is connected with main control system by network.
operation principle of the present utility model is: when milk cow enters milking parlour, at first the low frequency signal that milk cow id signal emitter with it sends is collected by the gate inhibition's formula reader in milking parlour porch setting, be sent to central control host and carried out identification record, after milk cow enters into separately the position of milking, the unit reader of milking that is arranged on the position of respectively milking gathers the low frequency signal that milk cow id signal emitter with it sends again, further determined the position of milk cow, this moment, identification reader activated high-frequency circuit work, the milk cow action message that acceleration transducer produces sends to be received by the unit reader of milking by high frequency and is sent to central control host.
The unit reader of milking in embodiment has adopted the PIC16LF1518T single-chip microcomputer, and the low frequency 125K of use controls conducting and the shutoff of metal-oxide-semiconductor as the excitation end by PWM, realizes the ASK modulation; Hyperfrequency 915M is used for the transmission of data, and milk cow id signal emitter is with it set up data communication, collection milk cow sign data; Connect by RS485 interface and main control system PC, the unified image data of controlling.
Adopt the native system performance indications of twofold frequency system higher than current most of dairy farms positioning identification system.At present, on market, most products adopts the single frequency band design, the subject matter of single frequency band design: if only adopt the low frequency mode, usually less than 1 meter, pedometer can't be realized telecommunication due to the operating distance of low frequency recognition; If only adopt the hyperfrequency mode, the lability that distributes due to ultra high frequency electrical field causes recognition accuracy rate not high (usually less than 95%).This control method combines advantage and the ultrahigh frequency remote transmission advantage of the accurate location of low frequency, makes the entire system performance reach level preferably, and effect is very good.Accurately locate the recognition rate〉99%.
