The invention controls the calving of cows in agriculture.

5 At the moment I am not aware of a technical solution to watch for cow calving. With the present invention, such monitoring of calving is possible.

Currently, the monitoring of the calving is based on the pastor's 10 visits to the barn or the camera's surveillance by the pastor. These both have the disadvantage of being tied to a specific location. It is not always possible to see the far. In addition, you must wake up at night or check the situation with the camera monitor.

The present invention can automate monitoring.

The invention controls the initiation of calving and when calving begins, the invention provides an alarm.

Calving surveillance is based on measuring the tail position of a cow. The cow raises its tail when it is moaning and urinating, but also when it exits. However, since the stalling situation is a much shorter event, it can be deduced from the position of the tail that calving begins. When starting the calving, the cow must keep its tail constantly or more frequently raising its tails upwards. It is to this continuous lifting of the tail, or to the frequent lifting of the tail, that the invented device, the calf-watcher, responds.

The invented device is attached to the root portion of the cow's tail by means of a collar 30 1. The device has a curved tube 2 with, for example, a steel ball 3. The tube position is sought such that in normal cow standing or resting position, the ball cannot be connected to circuit 4. Even when the cow is normally hi-.1 ·. · The ball tends to away from the coupling pin 35 '. repeat. When a cow begins to sow, it keeps its tail *: ": constantly up or lifting its tail.

The ball 3 can then roll along the tube 2 to the other end of the tube where the ball connects the circuit 4. The correct position of the tube for switching on the circuit can be tested while the cow is urinating or stabbing. Connected to the circuit: the tail transmitter 5 and the barn receiver 6. When .1: 1. the cow keeps its tail constantly up at '1' in the calving situation so that the circuit is constantly switched on or the circuit switches on due to the high frequency of the tail. Then 45 ... (transmitter or receiver, respectively) turns on (depending on which time setting is used) and sends the information, ···. Forward eg via a robotic phone ·; · 'to the pastor's paging device. to monitor the calving, thus avoiding 50'.1.1 calving and the resulting problematic situations such as calf death and so on.

The invention will now be described in more detail with reference to the accompanying drawing.

The sensor body is made of, for example, plastic and the bottom surface 5 of the sensor is shaped like a cow tail 6. On both sides of the sensor body there are lugs to which the elastic rubber collar 1 is fastened or the rubber lugs respectively are inserted between the lugs and tightened on the sensor. These solutions make the sensor light and easy to mount.

A curved tube 2 is placed inside the sensor. The tube can also be set to be adjustable with respect to the sensor body, whereby the coupling point can be varied to prevent coupling in normal cow standing or resting position. The body of the transducer 15 may also be shaped as tubular.

A corresponding adjustment can also be made by moving the sensor down or up in the tail. Since the change in tail position is not very large, the curvature of the sensor tube can be used to clarify the on-off connections that occur.

For example, a steel ball 3 moves inside the tube. Once it has risen, the steel ball rolls to the other end of the tube, where the ball performs the circuit switching between the pin 4, for example. A small power supply 5 25, such as a battery and a wireless mini transmitter 7, is placed in the sensor. When the steel ball 3 is turned on, the receiver will not trigger an alarm until the time required for calving is reached. Correspondingly, the sensor may include components for setting the time. Thus, the transmission signal 30 is only activated when the desired calving time limit is exceeded. This saves power on the power supply. In a parsnip vat, data can also be transmitted along the cord, as the cow cannot move as it would in the yard.

By providing information on the onset of calving in the early stages of calving, problems with single birth can be avoided.

These include, for example, choking on the calf, the calf's forehead, the size of the calf too large for the reproductive organs. At worst, both the cow and the calf are lost. Also in mouth-4j5 * 'herds have heavy run at night to check tarkast.'. calving. In order to completely avoid problems, constant monitoring is needed. On the farm with small human resources. for it is practically impossible. With the present invention, '· *' can be used to automate monitoring. In addition, the invention frees up 45 herdsmen to work elsewhere, because with current technology, it is easy to arrange the transfer of data to, for example, a cellphone · ... · or a pager.

You can also program check alarms on the unit in a timed sequence. When a cow is crying or urinating, an alarm can be sent so that the cowherd knows that the device is really working, especially during the day. When the cow starts to give birth, a calving alert will be given.

5 At night time, control alarms may be triggered by notification of a rise in the tail, either by urination or by dehydration, within a specified time interval. If no tail movement notification is received within the specified time, the device will trigger a false alarm and the caretaker will be woken up to verify the operation of the device. For example, if the cow had got the device out of its place.
