detailed description

The technical solutions of the present utility model will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

As shown in accompanying drawing 1, the wearable baby spitting alarm device of the present invention comprises the temperature sensing unit 2 that is arranged in the bib of the baby and is connected successively, the gate circuit unit 3, the conditioning circuit unit 4, the temperature detection unit 5, the statistics The judging unit 6 and the alarm or wireless transmitting unit 7 and the gate circuit unit 3 are connected with a power supply unit 1 .

These constituent units are sequentially assembled in the unit device area of numbers 1 to 7 on the baby bib carrier as shown in Figure 2, in which the contacts of the temperature sensing unit are densely distributed on the carrier bib, and the specific layout is shown in Figure 3, both There are columns and row contacts, and its function is that only when the temperature change signal sent by the row unit and the temperature signal sent by the column unit act at the same time, the gating circuit will transmit the signal to the conditioning circuit, and then detect whether to spit milk or water, which is also gating The function of the circuit (both the gate circuit not only selects the row of temperature but also selects the column of temperature, so that the detection is more accurate).

The specific arrangement method is set according to the actual needs to ensure that the arrangement method of each unit will not have any adverse effects on the baby.

As shown in Figure 1, the power supply unit provides energy for the entire device. The power supply unit 1 can be a button battery or other power supply that meets the requirements of the equipment. The power supply unit is replaceable so that the power is sufficient, and the power supply provides voltage for signal transmission. Once the baby vomits or chokes, the fluid or the like will wet the contact with the temperature sensing unit, and then the temperature of the fluid-immersed area will increase or decrease. The temperature increase or decrease is compared with the ambient temperature. out. The temperature sensing unit converts the temperature signal into a current signal, so as to transmit the information to the gating module; the main function of the gating module is to realize the multi-point acquisition of the temperature of the carrier, that is, the multi-point acquisition of the column and column, which is convenient for the subsequent devices to judge the fluid immersion The area of the liquid or the temperature of the liquid, the multi-channel gating module cannot cause measurement errors; the data directly collected by the temperature sensing unit needs to be calibrated, the calibration range is -10°C-50°C, and the signal needs to be filtered through the conditioning circuit. Amplification and other adjustments for subsequent data processing; after temperature calibration, the temperature is detected to set the temperature change and the fluid immersion area, that is, the temperature detection device. Compare to find out whether the temperature has changed or the degree of change; after the temperature is detected, the temperature is judged, that is, how much the temperature has risen or how large the area is immersed in the fluid. The contacts use multi-point acquisition, and the contacts are connected in parallel. In this way, when the spitting area is large, the current is relatively large, and when a high-temperature liquid or the like falls into the bib, the current is also large, so the size of the current can be used to judge the spitting area or the amount of milk or the temperature of the spitting object , use the size of the generated signal and the gate of the gate circuit to judge how much area there is a temperature change or the severity of the temperature change, that is, the statistical judgment of the temperature. After the statistical judgment, determine whether to alarm.
