The first weight acquisition component 11 is disposed on top of the first bracket 16, and the first weight acquisition component 11 abuts against the top plate of the first housing 15. The first housing 15 is used to provide protection for the first weight acquisition component 11, preventing dust, moisture, and other environmental factors from damaging the sensitive first weight acquisition component 11. The first bracket 16 is used to provide support for the first weight acquisition component 11, ensuring the stability of the first weight acquisition component 11 during the weighing process and improving the accuracy of the weighing. The abutment of the first weight acquisition component 11 against the top plate of the first housing 15 can provide additional stability, reduce vibration or movement that may occur during the weighing process, and thus improve the accuracy of the weighing.

[0042] In one embodiment, the metering host 1 further includes a third bracket 17, one end of the third bracket 17 is connected to the first shell 15, and the other end of the third bracket 17 is provided with a mounting portion 171, and the mounting portion 171 is detachably connected to the display device 12.

The second load sensor 211 is used to sense pressure, and the second transducer 212 is used to convert the analog signal from the second load sensor 211 into a digital signal. When an object applies pressure to the second load sensor 211, the second load sensor 211 deforms or undergoes other physical changes (such as changes in resistance, capacitance, or inductance), generating an analog signal. The second transducer 212 receives the analog signal from the second load sensor 211 and converts it into a digital signal. The display device 12 is used to display the digital signal.

[0047] In one embodiment, the metering host 1 further includes a first battery module 19, which is electrically connected to the first weight acquisition component 11 and the display device 12. The metering sub-device 2 includes a second battery module 25, which is electrically connected to the second weight acquisition component 21. The first and second battery modules 19, 25 can include one or more battery cells, such as lithium batteries, nickel-metal hydride batteries, or other rechargeable battery technologies, to meet the power and energy requirements of the system. The first battery module 19 is connected to the first weight acquisition component 11 and the display device 12 via wires or circuit boards, ensuring a stable power supply. Similarly, the second battery module 25 is connected to the second weight acquisition component 21 via wires or circuit boards, ensuring a stable power supply. Battery power allows the metering host 1 and metering sub-device 2 to be used without an external power source, increasing the portability and flexibility of the devices. Each metering host 1 and metering sub-device 2 has its own battery module, allowing them to operate independently in different locations without being restricted by power sources. The first battery module 19 can also be used to power the first communication module 13, and the second battery module 25 can also be used to power the second communication module 22.

[0048] In one embodiment, the metering host 1 further includes a first switch 110 for controlling the power supply to the first battery module 19; the metering slave 2 includes a second switch 26 for controlling the power supply to the second battery module 25.

For battery-powered devices, proper power control can reduce the frequency of battery replacement and lower long-term operating costs.

[0049] The combined metering device can be used in food production for real-time and accurate online statistics of multiple ingredients and multiple ingredients, which is convenient for counting the proportions of various components of food; for example, the first switch 110 is turned on to put the metering host 1 into working state, and the main ingredients (such as green peppers, potatoes, flour) are placed on the top plate of the first shell 15 of the metering host 1. The first load-bearing sensor 111 is subjected to pressure changes, and the first transmitter 112 converts the analog signal of the first load-bearing sensor 111 into a digital signal, and transmits it to the first wireless receiving module 132 via the first wireless sending module 131. The first wireless The receiving module 132 stores the digital signal in the first storage device 120 to obtain the weight data of the main ingredient; at the same time, the image photo of the main ingredient (i.e., the first item) is obtained through the image acquirer 141, the image feature extraction module 142 extracts features from the image information, and the comparison and recognition module 143 compares and recognizes the features extracted by the image feature extraction module 142 with the preset item feature data in the second storage device 144 to obtain the preset name of the first item, thereby completing the collection of the name and weight data of the main ingredient (first item), and the weight and name of the main ingredient can be displayed through the display device 12. Turning on the second switch 26 of the metering sub-machine 2 puts the metering sub-machine 2 into operation and connects it to the first storage device 120. Fixed or planned ingredients and auxiliary materials are placed on the metering sub-machine 2. When an ingredient or auxiliary material is taken, the pressure on the second load-bearing sensor 211 changes. The second transmitter 212 converts the analog signal from the second load-bearing sensor 211 into a digital signal, which is transmitted to the second wireless receiving module 222 via the second wireless communication module. The first wireless receiving module 132 stores the digital signal in the first storage device 120, thereby obtaining the weight data of the ingredients and auxiliary materials. With the metering host 1 calculating the weight of the main ingredient and the metering sub-machine 2 calculating the weight of the auxiliary materials during the production process, the weight data of the food during the production process can be quickly collected, achieving the purpose of efficient summary statistics.

At the same time, the second weight acquisition component 21 of the metering sub-machine 2 is used to obtain the weight data of the second item, and the weight data of the second item is transmitted to the first storage device 120 for storage. Multiple groups of data can be obtained simultaneously in the first storage device 120, and the display device 12 is used to display the weight data of the first item and the weight data of the second item stored in the first storage device 120, so that at least one group of weight data of the first item and multiple groups of weight data of the second items can be summarized and displayed on the display device 12 at the same time; the metering main machine and the metering sub-machine 2 can perform load-bearing measurement at the same time, thereby improving the working efficiency of weighing and measurement.
