In an intellectual scale and a method of using same, a plurality of chemical management modes is provided. The intellectual scale can be switched to operate under any one of these chemical management modes to detect and measure a chemical to obtain the type and the weight of the chemical under the current chemical management mode, and record the obtained type and weight of the chemical, so that a user is able to know the use state of the chemical.

1. An intellectual scale with a plurality of chemical management modes, comprising: a weighing unit arranged for measuring a weight of a chemical and generating a measurement signal; and the chemical being measured is accommodated in a container which has a radio-frequency identification (RFID) tag
1. An intellectual scale with a plurality of chemical management modes, comprising: a weighing unit arranged for measuring a weight of a chemical and generating a measurement signal; and the chemical being measured is accommodated in a container which has a radio-frequency identification (RFID) tag attached thereto for generating a wireless signal;a wireless signal receiving unit arranged for receiving the wireless signal and demodulating the received wireless signal into an identification signal;at least one key being used to input a switch signal; anda control unit with the chemical management modes, wherein the chemical management modes include: a stocktaking mode, under which the control unit checking and recording the type and a remaining quantity of the chemical; a lending mode, under which the control unit recording conditions of the chemical at the time of being lent for use; a return mode, under which the control unit recording conditions of the lent chemical at the time of being returned; an exhaustion mode, under which the control unit recording an exhaustion condition of the chemical; the control unit receiving the switch signal and switching to one of the chemical management modes based on the received switch signal; and the control unit also identifying a type of the chemical according to the identification signal and obtaining the weight of the chemical according to the measurement signal; further the control unit recording the type of the chemical and the weight thereof corresponding to a current chemical management mode under the chemical management modes, wherein the control unit compares the chemical under the lending mode with the chemical under the return mode to thereby record a use state of the chemical, and the control unit comprises an internally built threshold value, wherein the control unit transmits a warning signal to a warning unit when a difference between the weight of the chemical before using and after using exceeds the threshold value. 2. The intellectual scale with a plurality of chemical management modes as claimed in claim 1, wherein the RFID tag further includes control information of the chemical when the chemical is a type of controlled chemical, and the control information being transmitted via the wireless signal. 3. The intellectual scale with a plurality of chemical management modes as claimed in claim 2, further comprising a storage unit for storing the type, the weight, the control information and the use state of the chemical. 4. The intellectual scale with a plurality of chemical management modes as claimed in claim 2, further comprising a display unit for displaying the type, the weight, the control information and the use state of the chemical. 5. An intellectual scale with a plurality of chemical management modes, comprising: a weighing unit arranged for measuring a weight of a chemical and transmitting a measurement signal; and the chemical is accommodated in a container which has a barcode provided thereon;an identifying unit arranged for identifying the barcode and generating an identification signal;at least one key being used to input a switch signal; anda control unit with the chemical management modes, wherein the chemical management modes include: a stocktaking mode, under which the control unit checking and recording the type and a remaining quantity of the chemical; a lending mode, under which the control unit recording conditions of the chemical at the time of being lent for use; a return mode, under which the control unit recording conditions of the lent chemical at the time of being returned; an exhaustion mode, under which the control unit recording an exhaustion condition of the chemical; the control unit receiving the switch signal and switching to one of the chemical management modes based on the received switch signal; the control unit also identifying a type of the chemical according to the identification signal and obtaining the weight of the chemical according to the measurement signal; further the control unit recording the type of the chemical and the weight thereof corresponding to a current chemical management mode under the chemical management modes, wherein the control unit compares the chemical under the lending mode with the chemical under the return mode to thereby record a use state of the chemical, and the control unit comprises an internally built threshold value, wherein the control unit transmits a warning signal to a warning unit when a difference between the weight of the chemical before using and after using exceeds the threshold value. 6. The intellectual scale with a plurality of chemical management modes as claimed in claim 5, wherein the barcode further includes control information of the chemical when the chemical is a type of controlled chemical. 7. The intellectual scale with a plurality of chemical management modes as claimed in claim 6, further comprising a storage unit for storing the type, the weight, the control information and the use state of the chemical. 8. The intellectual scale with a plurality of chemical management modes as claimed in claim 6, further comprising a display unit for displaying the type, the weight, the control information and the use state of the chemical. 9. A method of using an intellectual scale with a plurality of chemical management modes, comprising the following steps: transmitting a switch signal to switch the intellectual scale to one of the chemical management modes, wherein the chemical management modes include: a stocktaking mode, under which the control unit checking and recording the type and a remaining quantity of the chemical; a lending mode, under which the control unit recording conditions of the chemical at the time of being lent for use; a return mode, under which the control unit recording conditions of the lent chemical at the time of being returned; an exhaustion mode, under which the control unit recording an exhaustion condition of the chemical;measuring a weight of a chemical to generate a measurement signal;identifying a type of the chemical to generate an identification signal;obtaining the type of the chemical and the weight thereof corresponding the current chemical management mode via the identification signal and the measurement signal, respectively; andrecording the type of the chemical and the weight thereof corresponding to the current chemical management mode, wherein the control unit compares the chemical under the lending mode with the chemical under the return mode to thereby record a use state of the chemical, and the control unit comprises an internally built threshold value, wherein the control unit transmits a warning signal to a warning unit when a difference between the weight of the chemical before using and after using exceeds the threshold value. 10. The method of using an intellectual scale with a plurality of chemical management modes as claimed in claim 9, further comprising the step of attaching an RFID tag to a container accommodating the chemical for identifying the type of the chemical. 11. The method of using an intellectual scale with a plurality of chemical management modes as claimed in claim 9, further comprising the step of printing a barcode on a container accommodating the chemical for identifying the type of the chemical.
