[0028] like Figures 1 to 6 As shown, the vehicle load monitoring device provided by the embodiment of the utility model is used to be arranged on a vehicle. The vehicle load monitoring device includes:

[0029] The communication device 1 includes a circuit module 12, which includes a communication module 122, a positioning module 123 and a main control module 124. The communication module 122 and the positioning module 123 are both electrically connected to the main control module 124. Among them, the communication module 122 plays a role in wireless communication, and the positioning module 123 is used to receive positioning information and wirelessly transmit the positioning information to the load data management platform (not shown in the figure, the load data management platform is also the background server) through the communication module 122, so that the background management user can obtain the vehicle's location information in real time (the specific functions and working principles of the communication module 122 and the positioning module 123 can refer to the existing technology and will not be repeated here).

[0030] The load detection unit includes a plurality of load sensors 2 and a load control module 3. The plurality of load sensors 2 are electrically connected to the load control module 3. The plurality of load sensors 2 are respectively arranged at different positions on the vehicle 4 to detect the load weight at different positions of the vehicle 4. The load control module 3 is electrically connected to the main control module 124. The load control module 3 is used to transmit the average load weight information detected by the plurality of load sensors 2 to the main control module 124, and wirelessly transmit the average load weight information to the load data management platform through the communication module 122, so that the backend management user can obtain the vehicle load information in real time.

[0031] Specifically, since the installation position of the load sensor 2 will affect the load data detected by it (i.e., the load measured by the load sensor 2 is different when the installation position is different), multiple load sensors 2 are set at different positions on the vehicle 4, thereby detecting the load at different positions of the vehicle 4. The load control module 3 calculates the average load according to the load data respectively measured by the multiple load sensors 2, thereby improving the accuracy of the load data (and, when a load sensor 2 is damaged, other load sensors 2 can continue to be used, thereby avoiding the situation where a load sensor 2 cannot work after being damaged); the load control module 3 then transmits the calculated average load information to the main control module 124, and the main control module 124 wirelessly transmits the average load information to the load data management platform through the communication module 122.

[0032] The vehicle load monitoring device provided by the utility model can realize the positioning function of the vehicle load monitoring device by setting a communication module 122, a positioning module 123 and a main control module 124; at the same time, by setting a load detection unit, the load detection unit includes a plurality of load sensors 2 and a load control module 3, and the plurality of load sensors 2 are respectively used to be set at different positions on the vehicle 4, so as to detect the load weight at different positions of the vehicle 4, and the load control module 3 transmits the average load weight information detected by the plurality of load sensors 2 to the main control module 124, and wirelessly transmits the average load weight information to the load data management platform through the communication module 122, so that the background management user can obtain the vehicle's position information and load weight information in real time, so as to facilitate the background management.

[0033] like Figures 1 to 5 As shown, as an embodiment, the communication device 1 also includes a housing 11, and the circuit module 12 (including the communication module 122, the positioning module 123 and the main control module 124) and the load control module 3 are all arranged in the housing 11 (the communication module 122, the positioning module 123, the main control module 124 and the load control module 3 are arranged in the housing 11 Figure 3 The multiple load sensors 2 are connected to the load control module 3 by electrical signals through cables (not shown). Figure 6 As shown, since the communication device 1 is generally arranged in the cockpit 41 of the vehicle 4 (the communication device 1 is generally arranged on the dashboard), and the load sensor 2 is generally arranged at the rear axle position of the vehicle 4, the distance between the load control module 3 and the load sensor 2 is relatively far, and the two need to be connected by a longer cable.

[0034] like Figures 1 to 5 As shown, as an embodiment, the circuit module 12 also includes a circuit board 121 arranged in the shell 11, the communication module 122, the positioning module 123, the main control module 124 and the load control module 3 are all arranged on the circuit board 121 and are electrically connected to the circuit board 121, and the communication module 122, the positioning module 123 and the load control module 3 are all connected to the main control module 124 through the circuit board 121 via electrical signals.

[0035] like Figures 2 to 4As shown, as an embodiment, a power supply connector 13 is provided on the shell wall of the shell 11, and the power supply connector 13 is electrically connected to the circuit board 121; the power supply connector 13 is used to be electrically connected to the battery (not shown) of the vehicle 4 (specifically connected by a cable), so as to power the vehicle load monitoring device. At the same time, the circuit module 12 also includes a battery 125 arranged in the shell 11, and the battery 125 is electrically connected to the circuit board 121. The battery 125 is used to power the vehicle load monitoring device after the vehicle load monitoring device loses the power supply from the battery of the vehicle 4. That is, the main power supply of the vehicle load monitoring device is the battery of the vehicle 4. When the battery of the vehicle 4 is in the power-on state, the vehicle load monitoring device is powered by the battery of the vehicle 4 and charges the battery 125; when the battery of the vehicle 4 is in the power-off state, the vehicle load monitoring device loses the power supply from the battery of the vehicle 4, and the vehicle load monitoring device is powered by the battery 125.

[0036] like Figure 2 and Figure 3 As shown, as an implementation manner, a first through hole 111 is provided on the shell wall of the shell 11 , one end of the power supply connector 13 is fixed on the circuit board 121 , and the other end of the power supply connector 13 is inserted into the first through hole 111 .

[0037] like Figures 1 to 5 As shown, as an embodiment, the communication device 1 further includes a display screen 14 disposed on the outer wall of the housing 11, the display screen 14 is electrically connected to the circuit board 121, the display screen 14 is electrically connected to the main control module 124, and the display screen 14 is used to display average load information. Since the communication device 1 is generally disposed in the cockpit 41 of the vehicle 4, the driver can quickly and intuitively know the current load information through the display screen 14.

[0038] like Figures 1 to 3 As shown, as an embodiment, the housing 11 includes a main housing 11B and a front cover 11A connected to each other, and the circuit module 12 is arranged in the main housing 11B; a mounting groove 113 is provided on the outer wall of the front cover 11A, and the display screen 14 is arranged in the mounting groove 113.

[0039] like Figures 3 to 5As shown, as an embodiment, the circuit module 12 also includes an overload alarm module 126, which is electrically connected to the circuit board 121, and the overload alarm module 126 is electrically connected to the main control module 124. The overload alarm module 126 is used to issue a corresponding alarm message when the average load weight detected by the multiple load sensors 2 is greater than a preset value (for example, the rated load weight (i.e., the preset value) is 10 tons. If the average load weight detected by the multiple load sensors 2 is greater than 10 tons, the main control module 124 controls the overload alarm module 126 to issue a corresponding alarm message), thereby reminding the driver so that the driver can know the overload information in time.

[0040] Specifically, the overload alarm module 126 includes a speaker (not shown) for issuing a sound alarm message and an indicator light (not shown) for issuing a light alarm message; when the average load detected by the multiple load sensors 2 is greater than a preset value, the main control module 124 controls the speaker to issue a sound alarm and controls the corresponding indicator light to light up to remind the driver. The speaker can be set in the housing 11, and the indicator light can be set on the shell wall of the housing 11.

[0041] like Figure 4 and Figure 5 As shown, as an embodiment, the circuit module 12 further includes a vibration sensor 127, which is disposed in the housing 11 and electrically connected to the circuit board 121 (the vibration sensor 127 can be specifically disposed on the circuit board 121), and the vibration sensor 127 is electrically connected to the main control module 124, and the vibration sensor 127 is used to detect the vibration signal of the vehicle 4. The main control module 124 is used to control the positioning module 123 to switch between the working state and the standby state according to the vibration signal value detected by the vibration sensor 127.

[0042] Specifically, when the vehicle 4 is in a stopped state, the vibration sensor 127 cannot detect a vibration signal or the detected vibration signal value is very small; when the vehicle 4 is in a moving state, the vibration signal value detected by the vibration sensor 127 is larger; by comparing the vibration signal value detected by the vibration sensor 127 with the set value, the state of the vehicle 4 is judged. When the vibration signal value detected by the vibration sensor 127 is greater than or equal to the set value, it means that the vehicle 4 is in motion, and the main control module 124 controls the positioning module 123 to enter the working state; when the vibration signal value detected by the vibration sensor 127 is less than the set value, it means that the vehicle 4 is in a stopped state, and the main control module 124 controls the positioning module 123 to enter the standby state; thereby, the positioning module 123 does not need to work all the time (because the position of the vehicle 4 does not change when the vehicle 4 is in a stopped state, the positioning module 123 does not need to work at this time. Of course, when the positioning module 123 is in the standby state, the positioning module 123 can be remotely awakened through the communication module 122) to save power consumption (the power consumption of the positioning module 123 is relatively large, especially when the vehicle load monitoring device is powered by the battery 125, the battery life of the vehicle load monitoring device will be shorter).

[0043] As an implementation method, the main control module 124 and the load control module 3 are both MCU micro control units.

[0044] As an implementation method, the communication module 122 is a 4G network communication module, that is, it can communicate on the 4G network. The positioning module 123 is a GPS positioning module, which can perform GPS positioning. Of course, in other embodiments, the communication module 122 and the positioning module 123 can also be other types (for example, the communication module 122 is a 2G / 4G dual-frequency network communication module, and the positioning module 123 is a GPS / BD dual positioning module, that is, the positioning module 123 is compatible with GPS positioning and Beidou positioning).

[0045] like Figure 2 and Figure 3 As shown, as an embodiment, a SIM card slot 128 for inserting a SIM card (not shown) is provided on the circuit board 121, and a second through hole 112 is provided on the shell wall of the shell 11 at a position corresponding to the SIM card slot 128, and the second through hole 112 is used for inserting the SIM card.

[0046] like Figure 6As shown, the embodiment of the utility model further provides a vehicle 4, in particular a truck, including the above-mentioned vehicle load monitoring device, in which a plurality of load sensors 2 are respectively arranged at different positions on the vehicle 4. The load sensors 2 can be arranged on four leaf springs at the front, rear, left, and right sides of the vehicle 4, at the beam / axle / frame of the vehicle 4, etc. (the specific installation position of the load sensor 2 can refer to patents such as CN218805564U).

[0047] As an embodiment, the communication device 1 is arranged in the cockpit 41 of the vehicle 4. The number of the load sensors 2 is four; the vehicle 4 includes a cargo box 42, the cargo box 42 is a rectangular parallelepiped structure, and the four load sensors 2 are respectively arranged below the four vertex positions of the cargo box 42 (specifically, the load sensors 2 can be arranged between the cargo box 42 and the frame 43).

[0048] The vehicle load monitoring device provided by the embodiment of the utility model can realize the positioning function of the vehicle load monitoring device by setting a communication module 122, a positioning module 123 and a main control module 124; at the same time, by setting a load detection unit, the load detection unit includes a plurality of load sensors 2 and a load control module 3, and the plurality of load sensors 2 are respectively used to be set at different positions on the vehicle 4, so as to detect the load weight at different positions of the vehicle 4, and the load control module 3 transmits the average load weight information detected by the plurality of load sensors 2 to the main control module 124, and wirelessly transmits the average load weight information to the load data management platform through the communication module 122, so that the background management user can obtain the vehicle's position information and load weight information in real time, so as to facilitate background management.

[0049] The above are only specific implementations of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
