Particularly, described sound identification module adopts LD3320 chip.
Particularly, described central controller adopts Freescale S9S12XEP100 family chip.
Particularly, described sound identification module and central controller parallel communications.
Particularly, described voice input module is microphone.
Operation principle of the present utility model is:
Described voice input module gathers voice signal and transfers to sound identification module, voice signal carries out contrasting with the action phrase in the list of phrases prestored and the action phrase identical with voice signal is sent to central controller by sound identification module, and central controller controls positive pole relay according to action phrase and/or negative pole relay carries out corresponding action.
The utility model comprises following advantage and beneficial effect compared to existing technology:
(1) the utility model adopts Voice command, because phonetic incepting has larger scope, in unexpected abnormality situation, related personnel can when making battery pack power-off with a certain distance from when electric automobile by voice command, and do not need closely to operate, greatly improve the fail safe of related personnel, realize the promptness of control operation, and Voice command is convenient simultaneously.
(2) by the break-make of Voice command positive pole control relay and/or negative pole relay, do not need artificially manually directly to contact high-tension line, guarantee the safety of related personnel further.
Accompanying drawing explanation
Fig. 1 is the theory diagram of the utility model based on voice-operated battery management system.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1, a kind of based on voice-operated battery management system, comprising: battery pack, positive pole relay, negative pole relay, voice input module, sound identification module, acquisition module (BMU) and central controller (BCU).
Connect the positive terminal of load after total anode serial connection positive pole relay of described battery pack, after total negative terminal serial connection negative pole relay, connect the negative pole end of load.Described voice acquisition module is for gathering voice signal and by transmitting voice signal to sound identification module.Voice signal carries out contrasting with the action phrase in the list of phrases prestored and the action phrase identical with voice signal is sent to central controller (BCU) by described sound identification module.Described central controller (BCU) controls positive pole relay according to the action phrase of sound identification module and/or negative pole relay carries out corresponding actions.In the present embodiment, described central controller (BCU) controls positive pole relay and negative pole relay disconnection or closed according to the action phrase of sound identification module.Positive pole relay and negative pole relay are operated simultaneously, make the operation of follow-up related personnel safer.Described acquisition module (BMU) is connected with central controller (BCU) signal, for gathering battery state information according to the control command of central controller (BCU) and by gathered battery state information transmission to central controller (BCU).
In the present embodiment, described voice input module is microphone.Described sound identification module adopts LD3320 chip.Described LD3320 chip is a " speech recognition " special chip.LD3320 integrated chip voice recognition processor and some external circuits, as AD, D/A converter, microphone interface, voice output interface etc.The microphone interface of LD3320 chip connects microphone, the register of voice recognition processor prestores the list of phrases of the action phrase comprising one or more, the phrase of list of phrases includes but not limited to, " disconnection positive pole relay ", " power-off ", " disconnected relay ", " lower electricity ", " pass power supply ", " powering on ", " startup ", " unlatching ", " closing relay " etc., also can adopt other phrases.The action directive of a control relay of the corresponding central controller of each the action phrase prestored in the register of sound identification module, or the action directive of a control relay of the corresponding central controller (BCU) of multiple different action phrase.As, the disconnection actuating of relay control command of the equal corresponding central controller (BCU) of action phrase of " power-off ", " disconnected relay ", " lower electricity ", " pass power supply "; " power on ", " startup ", " unlatching ", " closing relay " the closing relay action directive of the equal corresponding central controller (BCU) of action phrase.Adopt multiple brief, common phrase, avoid related personnel in case of emergency brain blank be difficult to recall specific action phrase and the situation that causes Voice command failure.
