E, it is suitably applied the design of Robot Design and intelligent carriage.

In the present embodiment, signal acquisition module uses infrared sensor；Specifically, infrared sensor is typically divided into actively With passive two kinds of working methods.And this secondary design just be passive type, i.e., when human body pass through sensor working region when, Sensor starting.But since the infrared energy that human body issues is very weak, so the detector of pyroelectric infrared sensor assembling Its distance only has 1-2m.What sensor generated enters microcontroller by conversion, amplification.

Intelligent closestool has used infrared sensor principle, when people comes into or when close to intelligent closestool, discharges horse automatically Bucket cabinet, when sit down the sponge for compressing high-end density when, trigger automatic reset switch, incude the movement of people, utilize infrared ray Physical property is come the sensor that measures.Infrared ray is also known as infrared light, it has reflection, refraction, scatters, interferes, absorbs etc. Property.Any substance can infrared radiation as long as itself has certain temperature (being higher than absolute zero).Infrared ray passes Sensor measurement Shi Buyu testee directly contacts, and because friction may be not present, and has high sensitivity, reacts the advantages that fast.

Infrared sensor includes optical system, detecting element and conversion circuit.Optical system can be divided by structure difference Transmission-type and reflective two class.Detecting element can be divided into temperature-sensitive detecting element and optical detection device by working principle.Thermal element It is thermistor that part, which is applied at most,.Temperature increases when thermistor is by infrared radiation, and resistance changes (this variation It may be that become larger be also likely to be to become smaller, because thermistor can be divided into posive temperature coefficient thermistor and negative temperature coefficient thermistor power Resistance), electric signal output is become by conversion circuit.The most commonly used is light-sensitive elements for optical detection device, usually by vulcanized lead, selenizing The materials such as lead, indium arsenide, antimony arsenide, mercury cadmium telluride ternary alloy three-partalloy, germanium and silicon doping are made.Infrared sensor is usually used in contactless Temperature measurement, gas composition analysis and nondestructive inspection, obtain extensively in fields such as medicine, military affairs, space technology and environmental projects Using.Coefficient resistance), electric signal output is become by conversion circuit.The most commonly used is light-sensitive elements for optical detection device, lead to Often it is made of materials such as vulcanized lead, lead selenide, indium arsenide, antimony arsenide, mercury cadmium telluride ternary alloy three-partalloy, germanium and silicon doping.Infrared ray passes Sensor is usually used in contactless temperature measurement, gas composition analysis and nondestructive inspection, in medicine, military affairs, space technology and environment work It is used widely in the fields such as journey.

Infrared sensor of the human body technical indicator:

(1) it load characteristic: is compatible with bearing power: 25W-200W entirely

(2) induction range: 120&ordm；Within coning angle 5-6m

(3) Lighting control:>250LUX automatic distinguishing<120LUX automatically turns on (indoor someone)

(4) the advanced and mature integrated circuit high-powered energy-saving of use, only 2~3 degree of year power consumption

(5) connection: three line series types

(6) operating temperature: -20 DEG C -+50 DEG C infrared intelligent battery-conserving switches utilize human body infrared induction principle, using elder generation Into integrated circuit and precision electronic element Multiple Combination form.What it is due to this secondary design is intelligent closestool, in conjunction with human body infrared Many advantage and disadvantage of sensor.

In the present embodiment, the communication module uses blue tooth wireless communication module；Specifically, bluetooth module is a kind of collection At the PCBA board of Bluetooth function, it is used for short-distance wireless communication, is divided into blue-teeth data module and blue tooth voice module by function.It is blue Tooth module refers to the chip basic circuit set of integrated Bluetooth function, is used for wireless network communication, is broadly divided into three categories type: Data transmission module remote control module etc..General module has the attribute of semi-finished product, is to carry out adding on the basis of chip Work, so that subsequent applications are more simple.As replace data cable short-distance wireless communication technology, bluetooth supports point to point with And the communication of point-to-multipoint, the various data and voice devices in family or office are wirelessly linked to be a piconet (Pico-net), several piconets can also further realize interconnection, form a distributed network (scatter-net), It is easily communicated to realize quick between these connection equipment.

Pin definition:

SET: pin is arranged in hardware principal and subordinate, and it is holotype that SET, which connects high level, under hardware setting, hanging or connect low level and be Slave pattern；

VCC GND: power input can connect 3.3V-5V voltage；

RXD: receiving end connects the end TXD of other serial equipments；

TXD: transmitting terminal connects the end RXD of other serial equipments；

CLR: memory clearing pin, the bluetooth module matched can search for the last bluetooth matched automatically after powering on Equipment, CLR pin connect the high level of 10US or more, can remove the unpaired message inside bluetooth module, instruct with " AT+CLEAR " Equally.

This secondary design is intelligent closestool, in order to control closestool each function realization, select HC-05 slave one Blue tooth wireless communication module.

Further, intelligent closestool control system further includes relay control module, for controlling the water pump of intelligent closestool, The relay control module is connect with the central controller.

In the present embodiment, electromagnetic type relay is generally made of iron core, coil, armature, contact reed etc..12V relay The course of work are as follows: as long as adding certain voltage at coil both ends, will pass through certain electric current in coil, to generate electromagnetism Effect, armature will overcome the pulling force of return spring to be drawn to iron core under the action of electromagnetic attracting force, thus dynamic with moving armature Contact and stationary contact (normally opened contact) are attracted.After coil blackout, the suction of electromagnetism also disappears therewith, and armature will be in spring Reaction force returns to original position, discharges movable contact and original stationary contact (normally-closed contact).It is attracted, discharges in this way, from And conducting, cutting in circuit is achieved the purpose that.For " normally opened, normally closed " contact of relay, can distinguish in this way: The stationary contact being in an off state when relay coil is not powered on, referred to as " normally opened contact "；Stationary contact in an ON state claims For " normally-closed contact ".

The selection of relay rated operational voltage is the most important technical parameter of relay.When using relay, The operating voltage of circuit (circuit i.e. where relay coil), the rated operational voltage of relay are answered where should considering first Equal to the operating voltage of place circuit.The operating voltage of circuit is the 0.86 of relay rated operational voltage where general.Pay attention to The workpiece voltage of place circuit must not be more than relay rated operational voltage, and otherwise relay coil is easy to burn.Relay Device is divided into two sides, and side is tip side, connection forceful electric power load；The other side is coil-end, connects light current drive control, be it is a kind of with The switch of smaller current control high power load.
