Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe.

It is described in the utility model multifunction nursing bed as shown in Figure 1 with the workflow of bluetooth controller.It first will be even Wiring is inserted respectively into nursing bed control unit interface itself and bluetooth controller interface, by lower switch, power conversion module 1 （Shown in Fig. 2）It is powered on to bluetooth controller, is in single-chip microcontroller 3 and waits making for serial ports interrupt status and bluetooth receiving module 2 Can end and receiving end be low level, be in bluetooth receiving module 2 under broadcast and reception state, carry out pairing with host computer until After successful matching and still bluetooth module is kept to be constantly under broadcast state, when host computer has care actions AT control instruction through indigo plant When tooth sending module is sent, bluetooth receiving module 2 can receive the command information from host computer, and by serial ports pin send to Single-chip microcontroller 3 is analyzed and processed, hard by control circuit control relay group according to analysis treated care actions control instruction The corresponding actuating of relay of part module 5, and be passed to through connecting line to nursing bed this body controller respective pin, to realize nursing bed The long-range real-time nursing of care actions.

Multifunction nursing bed bluetooth controller system described in the utility model is as shown in Figure 2.System includes power supply conversion Module 1, bluetooth receiving module 2, single-chip microcontroller 3, control circuit module 4, relay group hardware module 5（In Fig. 2 in the middle part of dotted line frame Point）, the bluetooth receiving module 2 in this case uses CC2540 for the BLU4.0 bluetooth module of core chips, and single-chip microcontroller 3 uses C52 Single-chip microcontroller.After bluetooth module successful matching, bluetooth receiving module 2 receives host computer and passes through the nursing bed that bluetooth sending module is sent AT signal control instruction is acted, is sent by serial ports pin to single-chip microcontroller 3 and is analyzed and processed, treated that nursing is dynamic according to analysis Make control instruction by control circuit module 4 control the corresponding actuating of relay of relay group hardware module 5, and through connecting line be passed to Nursing bed this body controller respective pin, to realize the long-range real-time nursing of nursing bed care actions.

Program flow chart in the utility model is as shown in figure 3, after bluetooth controller system electrification, bluetooth receiving module 2 enter broadcast pairing state, are waited for down always after successful matching.When bluetooth receiving module 2 receives host computer Information will be automatically sent in single-chip microcontroller 3 by the end serial ports TX, so that single-chip microcontroller 3 is generated an interrupt signal, into case statement Discriminance analysis processing is carried out, the actuating of relay is further controlled by I/O port according to instruction, outputs a signal to nursing bed itself Controller, thereby executing corresponding nursing movement；When bluetooth receiving module 2 is not received by the information of host computer, will always be in Wait state.

2 circuit of bluetooth receiving module in the utility model in this case as shown in figure 4, use CC2540 for core chips BLU4.0 bluetooth module, bluetooth receiving module 2RX, TX, BCTS are connected with C52 single-chip microcontroller TX, RX and an I/O pin, BRTS, BCTS are respectively data sending request and data transportation request signal port, and EN is level triggers model selection port, this The end EN is directly grounded in case, and bluetooth receiving module 2 is made to be constantly in broadcasting state, and the end BRTS is also directly grounded, and makes bluetooth Receiving module 2 is constantly under reception state, realizes the two-way communication of bluetooth controller and host computer and logical with single-chip microcontroller 3 Letter.Since the enable end of bluetooth receiving module 2 in the present case is directly grounded, bluetooth receiving module 2 quickly enters broadcast pairing It is matched under state, until the successful matching with host computer, the pairing indicator light after successful matching in bluetooth light.Work as bluetooth After receiving module 2 receives the signal of host computer, 3 receiving end of single-chip microcontroller is sent data to by the end serial ports TX.Work as bluetooth When the receiving end of module is received from the data of single-chip microcontroller 3, at this moment bluetooth module enters data into end BCTS automatically and sets low electricity It is flat, for waking up host computer, host computer is transferred data to after delay, automatically draws BCTS terminal potential after the completion of data transmission It is high.Wherein in the unilateral conduction that the effect of the diode at the end RX, TX is using diode, prevent from program importing single-chip microcontroller Bluetooth module is imported when 3.

Control circuit module 4 and 5 principle of relay group hardware module in the utility model are as shown in figure 5, single-chip microcontroller 3 identifies Treated action control signal connects single-pole double throw relay by 3 I/O mouthfuls of control transistor control circuit module 4 of single-chip microcontroller The relay of 5 corresponding nursing of device group hardware module movement, control signal are sent to this body controller of nursing bed, execute corresponding shield Reason movement.

Such as Fig. 6 of the utility model power conversion module 1, will be in this body controller of nursing bed using lm2596 in embodiment Power supply, which introduces bluetooth controller and is down to 5V, provides power supply use to bluetooth controller system.

Control circuit module 4 and 5 principle of relay group hardware module in the utility model is as shown in fig. 7, by resistance, hair Optical diode, relay, triode, diode composition.It is made of in the present case 10 identical control circuits, relay circuits Control circuit module 4 and relay group hardware module 5,10 care actions of corresponding nursing bed, respectively：Left turn, the right side It turns over, lift back, drop back, bent leg, flat leg, bedpan is opened, bedpan closes, self-timing A, self-timing B.It is a control electricity in Fig. 7 The schematic diagram on road and a relay circuit is controlled the closure of corresponding relay by the P2.6 pin of single-chip microcontroller 3, specifically：It is single Piece machine 3 handles control instruction information（Such as left turn）Afterwards, it corresponds to single-chip microcontroller 3 and controls the output pin P2.6 of the function to execution One low level of base stage of triode in the relay auxiliary circuit of the movement, the base stage of triode are receiving single-chip microcontroller 3 Signal after, the emitter and collector of triode is connected, and is attracted relay, and the port relay COM, SEL is connected, and will control Signal processed sends nursing bed to by output circuit and connecting line, and nursing bed can execute corresponding dynamic upon receipt of the signals Make.Simultaneously the luminous prompting relay is in attracting state to LEDs ON simultaneously.When relay is by working condition to stopping When work, controlled since the actuation of relay is the induction coil inside relay, and induction coil is the one of power-off Moment can generate huge electric current and be enough to puncture on triode, so this case is in consideration of it, devise a diode electricity Road, the effect of diode circuit are the huge current flows for consuming relay and generating in shutdown transient, prevent the triode in circuit Breakdown effect.

Bluetooth controller system line plate in this case is that related component is welded on control panel.So far, originally Utility model goal of the invention is accomplished.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
