[0034] Detailed Implementation

[0035] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0036] The remote control antenna assembly and operating machinery according to the present invention are described below with reference to the accompanying drawings.

[0037] like Figure 1 and Figure 7 As shown, in this embodiment, the remote control antenna assembly is used in the operating machinery, which includes a vehicle body and a boom 10 mounted on the vehicle body. The remote control antenna assembly includes a boom remote control antenna and a receiver 5 mounted on the vehicle body. The receiver 5 is used to receive and process the signal and perform signal conversion. The receiver 5 and the boom remote control antenna are connected by a cable 2. The boom remote control antenna includes an antenna radiator 1 and a signal processing unit. The boom remote control antenna is mounted on the boom 10. The antenna radiator 1 is used to receive and radiate radio frequency signals. The signal processing unit is electrically connected to both the antenna radiator 1 and the receiver 5. The signal processing unit is used to detect and process the radio frequency signals transmitted by the antenna radiator 1. The receiver 5 is used to receive and process the processed signal to achieve information interaction.

[0038] In this application, by mounting the boom remote control antenna on the boom, the antenna radiator can be effectively prevented from being blocked, thereby enabling more stable signal reception and meeting the long-distance communication requirements of the remote control transmitter. It should be noted that the vehicle body includes a chassis and a driver's cab and electrical control box mounted on the chassis. The receiver 5 can be mounted above the driver's cab or at the electrical control box. Specifically, the boom 10 includes multiple boom sections connected sequentially at their ends. The boom remote control antenna is mounted at the tail end of one of the boom sections. The antenna radiator 1 can be mounted on a boom section away from the vehicle body to ensure that the antenna radiator 1 can stably receive radio frequency signals or radiate radio frequency signals into the external space.

[0039] like Figure 6As shown, in this embodiment, the signal processing unit includes a detection module 4 and a transceiver front-end module 3. The detection module 4 is used to detect the signal transmission / reception type of the antenna radiator 1. The transceiver front-end module 3 is electrically connected to both the antenna radiator 1 and the detection module 4. The transceiver front-end module 3 is used to process the radio frequency signal of the antenna radiator 1 and switch between receiving and transmitting states according to the signal transmission / reception type to achieve information interaction. One end of the cable 2 along its length is connected to the receiver 5, and the other end is connected to both the detection module 4 and the transceiver front-end module 3. The cable 2 is laid along the extension direction of multiple arm sections, and the cable 2 is attached to the side wall of the arm section.

[0040] like Figure 1 As shown, in this application, a transceiver front-end module 3 is provided between the detection module 4 and the antenna radiator 1. The detection module 4 detects the radio frequency signal received by the antenna radiator 1 and transmits a control signal to the transceiver front-end module 3. After receiving the control signal, the front-end transceiver module determines the signal type. When the signal type received by the transceiver front-end module 3 is a transmit signal, the transceiver front-end module 3 switches to the transmit state and radiates the radio frequency signal to the outside through the antenna radiator 1. When the signal type received by the transceiver front-end module 3 is a receive signal, the transceiver front-end module 3 switches to the receive state and transmits the external radio frequency signal to the receiver 5 through the antenna radiator 1. Specifically, the cable 2 is a coaxial cable. The cable 2 can transmit radio frequency signals, DC signals, and discrimination signals simultaneously. For example, transmitting the discrimination signal through the cable 2 allows the transceiver front-end module 3 to easily switch between the low-noise amplifier 31 and the power amplifier 32. The design of the coaxial cable 2 can minimize system wiring and improve system integration and communication reliability.

[0041] like Figure 7 As shown, in this embodiment, an isolation cover 6 is also provided around the antenna radiator 1, the detection module 4 and the transceiver front-end module 3. The isolation cover 6 extends along the length of the antenna radiator 1 and serves to protect the antenna radiator 1, the detection module 4 and the transceiver front-end module 3, and prevent them from being damaged by bumps.

[0042] In this embodiment, the remote control antenna assembly also includes a mounting component. The mounting component is used to lock the isolation cover 6 to the boom section to ensure that the boom remote control antenna can be firmly installed on the boom section. The mounting component can be a threaded component in the prior art. The boom section has a mounting hole that is threaded with the mounting component. The isolation cover 6 has a mounting ear. The mounting component passes through the mounting ear and is inserted into the mounting hole to lock the boom remote control antenna to the boom section.

[0043] In this embodiment, the isolation cover 6 is provided with a mounting plate 7 for supporting the detection module 4 and the transceiver front-end module 3. The antenna radiator 1 includes an antenna substrate and an antenna radiation line. The antenna substrate is mounted on the mounting plate 7, and the antenna radiation line is laid on the antenna substrate and connected to the transceiver front-end module 3 to ensure stable signal transmission. The antenna radiation line is only used for radio frequency signal transmission, and no other electrical signals are emitted to the external space through the antenna radiator 1, so as to avoid external devices receiving too many interference signals.

[0044] In this embodiment, the transceiver front-end module 3 includes a low-noise amplifier 31, a power amplifier 32, and a power divider 33. The low-noise amplifier 31 is used to reduce and amplify the radio frequency signal, the power amplifier 32 is used to amplify the radio frequency signal transmitted by the receiver 5 and transmit it to the outside via the antenna radiator 1, and the power divider 33 is used to separate the low-noise amplifier 31 and the power amplifier 32. The cooperation of the low-noise amplifier 31, the power amplifier 32, and the power divider 33 enables efficient signal transmission.

[0045] like Figure 2 As shown, in the first embodiment, there are two power dividers 33, which are respectively arranged on both sides of the low noise amplifier 31 and the power amplifier 32. The radio frequency signal transmitted from the antenna radiator 1 to the receiver can be processed by the power divider 33 and then enter the low noise amplifier 31 and the power amplifier 32. Similarly, the radio frequency signal transmitted from the receiver to the antenna radiator 1 can also be processed by the power divider 33 and then enter the low noise amplifier 31 and the power amplifier 32. The transceiver front-end module 3 in the first embodiment has a simple structure, which is conducive to simplifying the structure of the remote control antenna assembly.

[0046] In this embodiment, the transceiver front-end module 3 further includes a switch control unit 34, which is used to control the switching between the low-noise amplifier 31 or the power amplifier 32 and the antenna radiator 1 according to the detection result of the detection module 4.

[0047] like Figure 3 As shown, in the second embodiment, the switch control unit 34 is located between the antenna radiator 1 and the low-noise amplifier 31 and the power amplifier 32. Since no filter 35 is provided in this embodiment, the second embodiment can be applied to sites with low environmental requirements.

[0048] In this embodiment, the transceiver front-end module 3 further includes a filter 35 for filtering the radio frequency signals emitted by the antenna radiator 1. The filter 35 is installed between the antenna radiator 1 and the switch control unit 34 or between the low noise amplifier 31 and the switch control unit 34.

[0049] like Figure 4As shown, in the third embodiment, a filter 35 is added between the antenna radiator 1 and the switch control unit 34. The filter 35 can filter out noise from the radio frequency signal received by the antenna radiator 1, which is beneficial to improving the detection accuracy of the subsequent detection module 4.

[0050] like Figure 5 As shown, in the fourth embodiment, the filter 35 is installed between the low-noise amplifier 31 and the switch control unit 34, enabling long-distance communication, minimizing system wiring, and improving system integration.

[0051] In this embodiment, the detection module 4 includes a transmit signal detection unit 41 and a transmit signal detection unit 42. The transmit signal detection unit 41 is used to receive the DC component of the signal in the antenna radiator 1 or the receiver 5 and generate a discrimination signal to distinguish the signal type. At the same time, it transmits the discrimination signal to the transceiver front-end module 3. The power supply detection unit 42 is electrically connected to the receiver 5 and is used to separate the radio frequency signal and the DC signal transmitted by the receiver 5, so that the radio frequency signal can be efficiently transmitted to the transceiver front-end module 3, and the switching between the receiving state and the transmitting state of the transceiver front-end module 3 is not affected by the DC signal.

[0052] The transmit signal detection unit 41 receives the DC component of the signal from the antenna radiator 1 or the receiver 5 and generates a discrimination signal that can distinguish the signal type. Simultaneously, it transmits the discrimination signal to the transceiver front-end module 3. When the transmit signal detection unit 41 receives the radio frequency signal transmitted from the antenna radiator 1 and detects a radio frequency signal of the receiving type, it sends a receiving type discrimination signal to the transceiver front-end module 3. Upon receiving the discrimination signal, the transceiver front-end module 3 disconnects the circuit on the power amplifier 32 side via the switch control unit 34. At this time, the transceiver front-end module 3 enters the receiving state, and the external radio frequency signal enters from the antenna radiator 1, passes through the low-noise amplifier 31, and is transmitted to the receiver 5 via the cable 2. When the transmit signal detection unit 41 receives the radio frequency signal transmitted from the receiver 5 via the cable 2, it transmits a transmit type discrimination signal to the transceiver front-end module 3. Upon receiving the discrimination signal, the transceiver front-end module 3 disconnects the circuit on the low-noise amplifier 31 side via the switch control unit 34. At this time, the transceiver front-end module 3 enters the transmit state, and the radio frequency signal will be radiated into external space via the celestial radiator. This design minimizes system wiring and improves the integration of the remote control antenna components and communication reliability.

The working machine can be a multi-arm pump truck, crane, or aerial work platform, etc., a mechanical device requiring stable long-distance communication. Since the working machine employs all embodiments of the remote control antenna assembly, it also possesses all the beneficial effects brought by the remote control antenna assembly, which will not be elaborated upon here.
