Abstract
A multi-functional warding device comprises a sensor, a wireless transmitter, a wireless receiver and a power supply. The sensor comprises a photodiode positioned on the clothing surface of a ward, a thermistor positioned in a middle layer of the clothing and two electric contactors positioned in the last layer of the clothing; the photodiode, the thermistor and the two contactors are connected with an input end of a signal processing circuit respectively, and an output end of the signal processing circuit is connected with an input end of an encoding circuit. The monitor can remind or alarm people when children or patients catching cold, urinating, dropping quilts during the night or when children leaving a warding range. The utility model is multi-functional, convenient and practical.
Description
One, technical field
The utility model relates to a kind of device that children, patient are guarded.
Two, background technology
The existing device that children, patient are guarded generally is the ward sensing circuit and wireless launcher to be set on one's body, and monitoring person monitors by receiver, handles variety of event at any time.Its design proposal, existing open in patents such as application numbers 88213256,92218694,99206087, the function that these devices have is comparatively single, the sensor of the employing special use that has, cost height, poor practicability.
Three, summary of the invention
The purpose of this utility model is a kind of simple in structure, monitor device of serving many purposes of design.
For this purpose, the multi-functional monitor device of the utility model design, comprise sensor, wireless launcher, wireless receiver and power supply, wireless launcher comprises and connects coding circuit, modulation circuit, high-frequency amplifier circuit and emitting antenna according to this that wireless receiver comprises receiving antenna, high-frequency amplifier circuit, demodulator circuit, shaping circuit, decoding scheme, the Display and Alarm Circuit that connects according to this; Sensor comprises photodiode, thermistor and two conductive contacts that are arranged on ward's clothing, also include signal processing circuit, photodiode, thermistor and two conductive contacts are connected with the input end of signal processing circuit respectively, and the output terminal of signal processing circuit is connected with the input end of coding circuit.
Owing to be provided with photodiode, thermistor and conductive contact, children, patient suffer from cold, urinate fall at wet, night by, perhaps children walk out monitoring apart from the time, this monitor can be pointed out, be reported to the police, and has multiple function, and is convenient and practical.
Four, description of drawings
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the circuit diagram of wireless launcher in this multi-functional monitor device.
Fig. 2 is the circuit diagram of wireless receiver in this multi-functional monitor device.
Fig. 3 is the circuit diagram of photosensor signal treatment circuit in this multi-functional monitor device.
Fig. 4 is the circuit diagram of temperature sensitive signal processing circuit in this multi-functional monitor device.
Fig. 5 is the circuit diagram of humidity inductive signal processing circuit in this multi-functional monitor device.
Five, embodiment
As shown in Figure 1 and Figure 2, the multi-functional monitor device of the utility model design comprises sensor, wireless launcher, wireless receiver and power supply.The sensor of multi-functional monitor device is located in custodial person's the clothing such as baby' diaper, and wireless launcher is worn on one's body the custodial person, and wireless receiver is held by monitoring person.Wireless launcher comprises and connects coding circuit 1, modulation circuit 2, high-frequency amplifier circuit 3 and emitting antenna 4 according to this that wireless receiver comprises receiving antenna 5, high-frequency amplifier circuit 6, demodulator circuit 7, shaping circuit 8, decoding scheme 9, the Display and Alarm Circuit 10 that connects according to this; Wherein, circuit 1 to circuit 10 is the universal electric circuit, and its 26S Proteasome Structure and Function is not tired one by one to be stated.Among the figure, when K switch 1, K2 are closed simultaneously, transmitter, receiver are in continuous emission, accepting state, this moment, the ward was if walk out monitoring range (being effective receiving range of wireless receiver), wireless receiver does not receive signal, and the transistor V4 in the Display and Alarm Circuit 10, V5 driven for emitting lights diode (LED) 1 send alerting signal, drives vibrating motor W, speech IC IC4 by transistor V6 simultaneously, send vibrations or audible alarm, play the missing effect of child that prevents.
Sensor comprises photodiode D1, thermistor R1 and two conductive contact L1, L2.Photodiode D1 is laid in the surface of clothing, is positioned at waistband position or chest, back, and when the bed clothes that cover as the ward were raised or played, photodiode D1 was subjected to the low-light irradiation to produce electricity output.Thermistor R1 is sandwiched in the clothing middle layer, and when the ward suffered from cold, catches cold body temperature decline, the resistance of thermistor R1 can change, thereby produces signal output.Two conductive contact L1, L2 are located at the innermost layer of clothing, are positioned at stern, shelves position, when ward's enuresis, when drenching clothing, introduce inductive reactance between conductive contact L1, L2, can produce signal output.
As Fig. 3, Fig. 4, shown in Figure 5, it is the signal processing circuit of above-mentioned each sensor, comprise comparer IC1, IC2, IC3, transistor V1, V2, V3, above-mentioned photodiode D1, thermistor R1 and conductive contact L1, L2 are connected between the input end X and power end Y of comparer, and signal processing circuit output terminal Z is connected to input end A, B, the C of coding circuit 1 respectively.The signal of above-mentioned each sensor output, make transmitter send different signals by signal processing circuit, receive processing by receiver, make LED 2, LED3, LED4 send alerting signal respectively, drive vibrating motor W, speech IC IC1 by transistor V6 simultaneously, send vibrations or audible alarm.Among the figure, adjustable resistor W1, W2, W3 are used to regulate comparing voltage value.
The type of alarm of above-mentioned Display and Alarm Circuit 10 can be selected, and selects audible alarm by day for use, helps in time to find that situation, night select for use vibrations to report to the police, and sleeps with interruption-free.
