As shown in fig. 1 and 2, the electric running apparatus includes: a vehicle body 10, a plurality of operation devices 20, and a communication system 30; the vehicle body 10 includes a frame 11; the plurality of running devices 20 comprise a walking assembly 21, an operation assembly 22 and a power supply assembly 23; the communication system 30 comprises a plurality of control modules 31 connected to the operating device 20. The control module 31 in this embodiment includes a control module a electrically connected to the operation module 22, a control module B electrically connected to the walking module 21, and a control module C electrically connected to the power supply module 23; information or instructions are transmitted between the plurality of control modules 31 via the frame 11. The operation device 20 works in cooperation with the corresponding control module 31 to operate the electric running device.

Specifically, the operation component 22 receives a walking instruction sent by a user and sends the walking instruction to the control module a, the control module a receives and transmits the walking instruction to the control module B through the frame 11, the control module B reads the walking instruction and executes the walking instruction, the walking component 21 is controlled to start to work, the walking component 21 comprises a walking motor and wheels, namely, the walking motor is controlled to work, and the walking motor is connected with and drives the wheels to roll so as to drive the electric driving equipment to walk on the ground. It can be appreciated that the control module C is communicatively connected to the control module a and the control module B via the frame 11. During operation of the electric drive apparatus, the control module C may be configured to control the running gear 21 according to the running information transmitted from the control module B received from the frame 11. Or the operation information of the operation assembly 22 and the electric quantity parameter information in the power supply assembly 23, which are transmitted on the control module a, send a charging instruction to the power supply assembly 23 so that the power supply assembly 23 supplies power to the walking assembly 21 according to the charging instruction.

It should be noted that, in the present embodiment, the plurality of control modules 31 transmit commands or information through the frame 11, and the commands or information sent or received by each control module 31 are coupled to the frame 11, instead of transmitting the commands or information by using a data wiring manner. The frame 11 is understood here to be a frame body with electrical conductivity as a supporting structure. Of course, in other embodiments, the frame body includes a conductive layer that conforms to the surface of the frame and extends generally along the frame. In the related art, data communication is performed between nodes through a dedicated communication harness between the control modules 31, and when the apparatus walks outdoors or performs a function, a problem of poor contact between the communication harnesses due to road bumps easily occurs. According to the application, the communication quality and the communication efficiency among the control modules in the electric running equipment are realized through the frame 11, so that the running efficiency of the electric running equipment is improved. By adopting the technical scheme of the application, the problems of poor contact and the like caused by adopting special communication wire harnesses can be avoided, or the problems of redundant interference of each wire harness and the like can be solved.

It should be further noted that, taking an example that the control module includes two control modules, i.e., the first control module and the second control module, which may be any two control modules of the control module a, the control module B, and the control module C, the specific types of the first control module and the second control module are not limited herein, when the first control module and the second control module communicate, the first control module sends information or an instruction including address information to the frame 11, and the second control module is configured to obtain the information or the instruction transmitted on the frame 11, and determine whether to receive and execute the information or the instruction based on the address information. Therefore, when receiving signals or instructions, the control module can directly read address information transmitted by the acquired signals or instructions to acquire the types and sources of the signals or instructions, and determine the execution objects for transmitting the signals or instructions according to the types and sources of the signals or instructions, so that the efficiency and the accuracy of data transmission of a communication system are improved, and the integration and the allocation of information are facilitated.

In some embodiments, fig. 3 is a schematic structural diagram of a communication system in an electric driving apparatus according to an embodiment of the present application. As shown in fig. 3, each control module 31 includes a controller 311 and a transceiver 312. Transceiver module 312 includes modem module 3121, signal amplification circuit 3122, detection circuit 3123, and signal coupling module 3124. The modem module 3121 and the signal coupling component 3124 constitute a transmitting unit. In this way, the controller 311 transmits information or instructions to the modem module 3121 such that the modem module 3121 modulates the information or instructions and transmits the modulated information or instructions to the vehicle frame 11 through the signal coupling assembly 3124.

In some embodiments, signal coupling component 3124, detection circuit 3123, signal amplification circuit 3122, and modem module 3121 constitute a receiving unit. In this way, the signal coupling component 3124 couples information or instructions transmitted through the vehicle frame 11 to the detection circuit 3123, and the detection circuit 3123 filters the information or instructions transmitted by the signal coupling component 3124. The signal amplifying circuit 3122 amplifies the filtered information or command and outputs the amplified information or command to the modem module 3121, and the controller 311 can receive the information or command demodulated by the modem module 3121.

Specifically, the carrier center frequency of the modem module 3121 is 10MHz or more and 12MHz or less. In some embodiments, the carrier center frequency of the modem module 3121 is approximately 10.7MHz. The information or the instruction output by the controller 311 is a parallel digital signal, the modem module 3121 loads the digital signal onto the carrier with the center frequency of 10.7MHz, modulates the digital signal loaded onto the carrier with the center frequency of 10.7MHz, and the signal coupling component 3124 couples the modulated digital signal onto the frame 11, so as to realize the transmission of the information or the instruction output by the controller 311.

The specific process of the controller 311 receiving information or instructions sent by another controller through the frame 11 is as follows: the detection circuit 3123 filters the information or instructions transmitted by the signal coupling component 3124 to obtain an analog signal with a carrier center frequency of 10.7MHz, then the signal amplification circuit 3122 amplifies the analog signal with a carrier center frequency of 10.7MHz, and the modem module 3121 demodulates the amplified analog signal with a carrier center frequency of 10.7MHz to output a digital signal to the controller 311. In some embodiments, the signal amplifying circuit 3122 may be integrated in the modem module 3121, that is, the modem module 3121 may amplify the analog signal with the carrier center frequency of 10.7MHz and output the digital signal to the controller 311 through the demodulation of the amplified analog signal with the carrier center frequency of 10.7 MHz.

Signal coupling component 3124 may function to bypass high frequency noise. In some embodiments, referring to fig. 3, the signal coupling component 3124 is configured as a safety capacitor having a range of values: c is less than or equal to 1000pF. In some embodiments, signal coupling component 3124 may also be configured as an inductor for coupling signals. The range of the capacitance value of the signal coupling component 3124 is: c is less than or equal to 1000pF. Typically, the typical value of the distributed inductance of the capacitance range is L.ltoreq.5μH, i.e. the coupling capacitance of 1000pF has a distributed inductance of μH and the parallel resonance frequency is f.ltoreq.7MHz. That is, the range of the capacitance of the signal coupling assembly 3124 is: c is less than or equal to 1000pF, and has better decoupling effect on noise below 10 MHz. The signal coupling component 3124 is further used for filtering the transmitted information or instructions through the detection circuit 3123 to obtain an analog signal with a carrier center frequency of 10.7MHz, so that the signal quality of the demodulated signal of the input modem module 3121 can be ensured. It should be noted that, in selecting the capacitance value of the coupling capacitor, a person skilled in the art needs to set the capacitance value according to a specific working condition of the electric driving apparatus. The application does not limit the capacitance of the coupling capacitor.

In some embodiments, the controller 311 and the transceiver 312 are covered with an insulating material; the detection circuit 3123 is provided with a conductive layer near one end of the frame 11; or the side of the modulation and demodulation module 3121 close to the frame 11 is provided with a conductive layer; a signal coupling assembly 3124 is formed between the conductive layer and the frame 11; that is, the signal coupling assembly 3124 in the above embodiments may be constructed of a conductive layer and the frame 11; the conductive layer is electrically connected to the detection circuit 3123 and the modem module 3121; thus, the signal coupling assembly 3124 is directly composed of the conductive layer and the frame 11, which saves the arrangement of the signal coupling assembly 3124 and improves the space utilization of the whole communication system. It will be understood, of course, that the range of values for the signal coupling assembly 3124 formed between the conductive layer and the frame 11 is as follows: c is less than or equal to 1000pF, so the size of the cross-sectional area of the conductive layer and the distance between the conductive layer and the frame 11 can be set according to the value range C of the coupling capacitance is less than or equal to 1000 pF.

In some embodiments, the control module 31 is configured to send information or instructions to the frame upon detecting that the communication system is in idle mode. The control module is further configured to set the communication system to an idle mode when no information or instructions transmitted by the vehicle frame are received within a preset time. In the actual communication process, the two control modules need to transmit information or instructions through the frame 11 at the same time. For example, in the above embodiment, the control module a transmits information or instructions to the control module B through the frame 11, and the control module C also transmits information or instructions to other control modules through the frame 11. In order to avoid transmission competition of information or instructions on the frame 11, when the control module a does not receive the information or instructions transmitted by the frame 11 within a preset time (it should be noted here that the control module a may specify the information or instructions sent by the control module according to the address information, or may receive the information or instructions sent by the control module C). In other words, the control module C does not send information or instructions to the frame 11 within the preset time, so that the control module a can send information or instructions to the frame, and thus, transmission competitiveness of information or instructions on the frame 11 can be avoided.

In addition, it should be noted that the communication system disclosed in the embodiment may be applied to various electric driving devices. By way of example, it is applicable to riding lawn mowers and other riding electric machines operating indoors or outdoors, where other functions than walking can be achieved by outputting other forms of power in addition to walking on the ground, such as riding snowploughs, riding agricultural machines, riding mopeds, riding sweepers, and all terrain vehicles, etc. The specific type of the specific electric power running apparatus is not specifically limited herein.
