As a kind of implementation, also comprise reset switch 50, for controlling the position of on and off switch or machine shaft 70, reset.Described reset switch 50 comprises two parts, the one, and power knob, makes system works or closes; The 2nd, SR is pressed before quitting work, and mainly makes machine shaft position reset, for work and prepare next time.
Preferably, described power module 40 adopts battery powered, such as No. 5 battery powered or button cell etc.
Described signal processing and control module 20, preferably adopt super low power consuming single chip processor, single-chip microcomputer 201 periphery configures have and power circuit 202, motor-drive circuit 203 and infrared signal circuit for generating 205, infrared receiving processing circuit 206 etc., described circuit is connected with respective modules respectively, this single-chip microcomputer in the most of the time in resting state, to save electricity consumption, when liquid level is during lower than infrared bright finish, liquid in pipe becomes air, the respective signal that single-chip microcomputer is sent by infrared light receptor 80 is waken up, example as shown in Figure 4, super low power consuming single chip processor 201 is processor, cooperation is with peripheral circuit, drive and control the behavior of modules, there is respectively the power circuit 202 being connected with power module 40, the motor-drive circuit 203 being connected with motor module 60, the infrared circuit for generating 206 being connected with infrared emittance 10, the infrared receiving processing circuit 205 being connected with infrared remote receiver, and further, comprise the reseting switch circuit 207 being connected with reset switch 50, the Wi-Fi drive circuit 204 being connected with Wi-Fi wireless transport module 30 etc.
Described infrared receiving processing circuit 205, for to receiving infrared electro signal and processing, to remove clutter noise and the background noise receiving, eliminates the impact of ambient light and other interference.
Fig. 5 is described infrared receiving processing circuit 205 embodiment schematic diagrams, comprising:
Preposition filtering and amplifying circuit 21, delay circuit 22, subtraction circuit 23 and amplifying circuit 24, described infrared receiving processing circuit 205 is essentially delay comparison circuit, because the infrared electro signal receiving is inevitably subject to the interference of more stable ambient light, the signal of telecommunication receiving is drawn high to some specific level, in order to eliminate this interference, preposition filtering and amplifying circuit 21 amplifies the also noise of the burst of filtering high frequency by primary signal, delay circuit 22 enters subtraction circuit 23 with signal below more jointly by signal delay a period of time, in subtraction circuit 23, the level of a rear time deducts the level of last time as the output of subtraction circuit, its output characteristic is as follows: while being liquid in tube for transfusion always, before and after the delay of input, level is a certain stable level, this particular value is determined by extraneous bias light intensity, subtraction circuit output approaches 0V voltage, when only the liquid in tube for transfusion sports air, the difference to the infrared Absorption ability of certain wavelength due to air and liquid, the level that the level of a rear time deducts the last time 0V voltage of not reacceesing, but one on the occasion of voltage, the moment that this voltage occurs is the moment that liquid level passes through infrared light sensing device.The voltage amplification of finally by amplifying circuit 24, subtraction circuit being exported, enters single-chip microcomputer 201.Single-chip microcomputer detects high level and is waken up, and low level does not process.By a series of processing of described infrared receiving processing circuit, no matter extraneous background light intensity, delay comparison circuit can both be kept to 0V automatically and accurately, eliminates its impact, therefore can identify liquid level by the moment of infrared light sensing device, reach the object of removing external interference.
The opening and closing of described infrared transmitter 10 and infrared light receptor 80 are controlled by signal processing and control module 20, can allow in theory infrared transmitter 10 and infrared light receptor 80 1 direct-opens, but because transfusion time is conventionally long, and starting in a period of time of transfusion, the probability of infusion-completed is very low, then the probability of infusion-completed improves constantly, as a kind of special processing mode, in order to save power consumption, the present invention adopts a kind of timetable to control the opening and closing of infrared transmitter, the feature of described timetable is, the a period of time of starting working in whole device just, the working time of infrared transmitter is very short, while not working, be closed, to save power consumption, continuation along with the time, its working time constantly extends, a until time point, it will be worked incessantly.Utilize this timetable, both can save power consumption, can meet with maximum of probability the reliability of equipment again.
In the case, can in single-chip microcomputer, design a timing routine or at SCM peripheral, a timing circuit is set, for timing.Following table is the preferred exemplary of the operating schedule of infrared transmitter of the present invention.It is as shown in the table, infrared transmitter is received the control of signal controlling and processing module, the a period of time of starting working at warning clip, the open frequency of infrared transmitter (the startup frequency of infrared transmitter, be the infrared transmitter number of starts per minute) less, continuation along with the time, the corresponding increase of infrared transmitter open frequency, the time stopping transfusion being detected better, reduce the power consumption of infrared transmitter, for example, in 30 minutes after powering on, startup per minute 1 time, in 30-50 minute, startup per minute 2 times, in 50-60 minute, startup 4 per minute is inferior, to starting frequency, control flexibly.
It should be noted that, the first intermediate plate 1 of the present invention and the second intermediate plate 2 are just distinguished for ease of describing, be not illustrated in while realizing and must carry out according to this labelling, such as, infrared transmitter 10 also can be arranged in the second intermediate plate 2, and motor module 60 is arranged in the first intermediate plate 1 (similarly, the motor shaft 70 of motor module 60 is connected with cylindrical rotating module 5), in cavity, be provided with signal processing and control module 20 and power module 40 and can be arranged on arbitrarily in the first intermediate plate 1 or the second intermediate plate 2, can not limit the present invention with this.Wi-Fi wireless network of the present invention can be both the Wi-Fi technology adopting, and can be also the W-Lan technology adopting, and can not be interpreted as and only adopt Wi-Fi technology.
The present invention is installed together electric machine and infrared sensing apparatus, and adopt super low power consuming single chip processor to do control system, use battery powered, make this warning clip build less, the present invention simultaneously makes clip shape, simply clamp tube for transfusion, greatly facilitate at narrow beside sickbed and use, be easy to apply.
Compared with prior art, the invention provides a kind of easy to operate, volume is little, lightweight equipment, device is made clip shape, feature is just to use extremely convenient and simple, saved complicated actuating device simultaneously, and the mode that adopts direct folder to close, and can make full use of more common wireless network (such as Wi-Fi, W-Lan etc.), can seamlessly rapidly warning message be passed to wireless network server, aspect reception signal processing, also the retardation ratio that has adopted innovation mode is eliminated the impact of bias light, reduced the processing time, promoted real-time.
The present invention also provides a kind of transfusion method for controlling stopping, comprising: sending and receiving infrared light, detects infrared signal level, if infrared signal level being detected changes, close the sending and receiving of infrared light, drive motors rotates, and motor rotation axis drives rotating module to clamp tube for transfusion.
Especially, as shown in Figure 6, the program flow diagram for a kind of method for controlling stopping of infusing, comprising:
301, system powers on,
