Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

As shown in fig. 1, in this embodiment, the multifunctional collecting device includes: the controller module 10 comprises a conversion circuit 20, a temperature sensitive element 30, a pressure sensitive element 40 and an acceleration sensitive element 50.
Those skilled in the art will appreciate that the configuration shown in fig. 1 does not constitute a limitation of the serial communication conversion apparatus, and may include more or less components than those shown, or some components in combination, or a different arrangement of components.
The temperature sensor 30 is a component that collects element temperature information or displays element temperature change, for example, a thermistor that collects battery temperature information or displays battery temperature change. The characteristic of the temperature sensitive element 30 is changed according to the change of the temperature, and the current temperature information is determined according to the current characteristic of the temperature sensitive element 30, such as a mercury liquid column in a thermometer, which is changed according to the change of the environmental temperature information, and the interval between mercury atoms between mercury is changed according to the change of the temperature. When the temperature rises, the space between the mercury atoms becomes large, the volume expands, and the mercury liquid column rises. In this embodiment, the temperature sensitive element 30 collects the battery temperature information to be collected according to the collection starting instruction, and sends the collected battery temperature information to the component of the controller. The pressure sensitive element 40 is a component for collecting pressure information, and the pressure sensitive component changes along with the change of the pressure information, and reflects the change of the pressure information according to the change of the pressure sensitive element 40. The acceleration sensing element 50 is a component for collecting acceleration information, and the acceleration sensing element changes according to the change of the movement acceleration of the object, otherwise, the change of the acceleration of the object can be reflected through the change of the acceleration sensing element 50.

The conversion circuit 20 is a circuit that converts a received signal, and the conversion circuit 20 may convert the received signal by amplifying, modulating, or the like. In this embodiment, the converting circuit 20 may amplify and modulate the received information, so that the received information meets the requirement of transmission. The received information is temperature information, pressure information or acceleration information of battery deformation of the battery.
The controller module 10 is connected to the temperature sensor 30, the pressure sensor 40, the acceleration sensor 50, and the converting circuit 20 respectively.

The pressure information and the acceleration information are the same as above, and are not described herein again.
In specific implementation, when the type of information to be acquired by the upper computer is multiple information, the controller module 10 sends a start acquisition instruction to the multiple sensitive elements, the multiple sensitive elements acquire the start acquisition instruction according to the received start acquisition instruction and feed back the acquired information to the controller module 10, the controller module 10 sends the acquired information to the conversion circuit 20 to be amplified and modulated to obtain information to be sent, and finally the information to be sent is sent to the upper computer. For example, if the type of information to be acquired by the upper computer is temperature information and pressure information, the controller module 10 sends a start acquisition instruction to the temperature sensitive element 30 and the pressure sensitive element 40, the temperature sensitive element 30 and the pressure sensitive element 40 respectively acquire the temperature information and the pressure information and send the acquired temperature information and pressure information to the controller module 10, and the controller module 10 sends the acquired temperature information and pressure information to the conversion circuit 20 for amplification and modulation, and finally sends the amplified temperature information and pressure information to the upper computer. When the host computer needs to collect other kinds of information, the processing is the same as above, and the details are not repeated here.
It should be understood that the upper computer may be a vehicle control device installed in the vehicle, or may be a vehicle remote control device, such as an ECU. The acquisition instruction may be an instruction sent by the upper computer according to a requirement, and the instruction includes a kind of information to be acquired, such as at least one of temperature information, pressure information, or acceleration information. The acquisition starting instruction is an instruction generated by the controller module 10 to start the sensitive element to acquire information. The information to be sent is amplified and modulated information, and the information can be sent to an upper computer through a network or a connecting line.
The invention provides a multifunctional acquisition device and a multifunctional acquisition sensor, wherein a controller module 10 generates a start acquisition instruction according to an information acquisition instruction, controls a temperature sensitive element 30, a pressure sensitive element 40 and an acceleration sensitive element 50 to acquire and feed back temperature information, pressure information and acceleration information of a battery, then a conversion circuit 20 amplifies and modulates the temperature information, the pressure information and the acceleration information of the battery to obtain information to be sent, and sends the information to be sent to an upper computer. In the prior art, one sensor cannot acquire a plurality of information simultaneously, for example, when measuring a battery bulge, if a battery pressure sensor, a battery bulge acceleration sensor and a battery temperature sensor are respectively installed during measuring the battery bulge, and the three sensors are simultaneously installed, the sensor is large in size, and the plurality of sensors cannot guarantee the same position information on the battery, so that the problem of inaccurate measurement and the like is easily caused.
