The livestock and poultry information acquisition device

Technical field

The utility model belongs to the cultural technique field, relates to a kind of information acquisition device, especially a kind of livestock and poultry information acquisition device.

Background technology

The collection of livestock and poultry individual information and reception and processing are the important process that modernization is cultured.Do not have the livestock and poultry message pick-up to handle means if culture the place, it is individual and according to growth of animals or poultry needs timely adjustment breeding environment to be difficult to distinguish livestock and poultry.And the control lag of breeding environment usually causes and stress wait the problem that is unfavorable for growth of animals or poultry.

Understand according to the applicant, handle in order to realize livestock and poultry information acquisition, at present livestock and poultry individual identification and information have adopted radio frequency (RF) technology, promptly receive by radio frequency receiver to be positioned at the livestock and poultry radiofrequency signal sent of information acquisition device on one's body, and it is discerned and information acquisition.But the wireless RF chip of existing information collector is in running order for a long time, and power consumption is big, is unfavorable for energy-conservation, obviously reasonable inadequately.

Summary of the invention

The primary and foremost purpose of utility model is to propose a kind of low-power consumption, energy-conservation livestock and poultry information acquisition device.On this basis, the utility model also will propose to gather the livestock and poultry information acquisition device of the individual multiple physiologic information of livestock and poultry in good time.

In order to reach above primary and foremost purpose, livestock and poultry information acquisition device of the present utility model contains wireless signal transmission circuit, and single-chip microcomputer and vibration receiving circuit, the output terminal of described vibration receiving circuit connects the oscillator signal input end of single-chip microcomputer, described wireless signal transmission circuit is that the wireless signal with dormant state sends chip, the emission control termination wireless signal transmission chip of described single-chip microcomputer

The control end.

In order to reach further purpose, livestock and poultry information acquisition device of the present utility model also comprises multiple sensors, and the output terminal of described sensor connects the signal input part of single-chip microcomputer.Particularly, sensor can comprise the vibration transducer of monitoring gait, the fine motion sensor of monitoring pulse and the temperature sensor of monitoring body temperature etc.

During work, various sensors can be gathered information such as the gait, body temperature, pulse of the physiologic information of reflection livestock and poultry individuality, send the single-chip microcomputer storage to, and wireless signal sends chip and is in dormant state usually.Have only after the vibration receiving circuit receives extraneous oscillator signal (usually when livestock and poultry individuality enter when being fixed in 3 meters left and right sides scopes of correct position receiving processor), pass through Single-chip Controlling, the wake on wireless signal sends chip, make it externally send the information of being gathered, be the receiving processor that closes on and receive.After Information Monitoring is sent completely, wireless signal sends chip and enters energy-conservation dormant state once more, thereby reduce power consumption greatly, save electric energy, need not to be equipped with the high capacity cell power supply, can send under the prerequisite of the livestock and poultry relevant physiological information that collects in assurance, for condition has been created in the compact and low power consumption of information acquisition device in good time.

Embodiment

Embodiment one

The livestock and poultry information acquisition device of present embodiment mainly contains MSP430F149 type single-chip microcomputer, the wireless signal transtation mission circuit that the GW100B chip constitutes, the vibration receiving circuit that the J04P chip constitutes, the vibration transducer that the ND chip constitutes, the fine motion sensor that the SV801 chip constitutes as shown in Figure 1.

Connect the oscillator signal input end of single-chip microcomputer by the modulate circuit of parallel resistance R9A and capacitor C 10 formations as

J04P chip

2,4 pin of vibration receiving circuit, promptly receive pin, when receiving electromagnetic signals not, 4 pin of J04P are the low level output state, output becomes high level state after receiving electromagnetic vibration signal, output signal is input to single-chip microcomputer and receives pin after filtering and current-voltage conversion, single-chip microcomputer is connected with oscillator signal input end 20 pin of single-chip microcomputer MSP430F149 after handling this signal by interrupt function.2 pin connecting resistance R9A of J04P chip and input end and the ground connection of capacitor C 10U, 4 pin connecting resistance R9A of J04P chip and the output terminal of capacitor C 10U, 1 pin of J04P chip connects power supply.GW100B chip as the wireless signal transtation mission circuit has dormant state, and 1,2,4 pin are connected with
