Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to remote controller control system technical field, especially in a kind of remote controller with safety distance communication. BACKGROUND
[0002] In current industrial applications, the widespread use of remote controllers has greatly improved work efficiency, especially in scenarios that require remote control of vehicles or robotic arms and other equipment. However, as the operating distance flexibly changes from being in close proximity to the equipment to being several meters or even further away, operators face new challenges in safety when using remote controllers for work. In particular, when the operator is located far away from the receiver (such as the vehicle control unit), it may be difficult to fully perceive the work environment due to limited visibility or excessive distance, increasing the risk of misoperation or ignoring potential dangers. In order to address this safety hazard, it is particularly important to develop a remote controller with intelligent safety distance control function. That is, when the remote controller reaches a limited distance from the receiver (the distance can be changed), the remote controller can also make the receiver enter the emergency stop state without pressing the emergency stop. SUMMARY
[0003] According to the embodiments of the utility model, a remote controller with safety distance communication is provided, comprising:
[0004] A distance measuring sensor is used to detect the distance from an external receiver.
[0005] A single-chip microcomputer is used for data processing.
[0006] A 485 transceiver chip is connected to the single-chip microcomputer and the distance measuring sensor, and is used to receive operation requests, set the distance measuring sensor to fast automatic continuous measurement, and upload the distance data measured continuously by the distance measuring sensor to the single-chip microcomputer.
[0007] Further, it further comprises a wiring terminal connected to the distance measuring sensor and the 485 transceiver chip.
[0008] Further, the communication protocol between the distance measuring sensor and the 485 transceiver chip is Modbus RTU communication protocol.
[0009] Further, the baud rate of the distance measuring sensor is consistent with the baud rate of the serial port of the single-chip microcomputer.
[0010] Further, the baud rate of the serial port of the single-chip microcomputer and the distance measuring sensor is 115200.
[0011] Further, it further comprises:
[0012] A first capacitor is connected to pin 11 of the 485 transceiver chip at one end.
[0013] The first diode has one end connected to pin 11 of the 485 transceiver chip, and the other end of the first diode is connected to the other end of the first capacitor and then grounded.
[0014] The second capacitor has one end connected to pin 12 of the 485 transceiver chip.
[0015] The second diode has one end connected to pin 12 of the 485 transceiver chip, and the other end connected to the other end of the first capacitor and then grounded.
[0016] According to an embodiment of this utility model, a remote control with secure distance communication utilizes a sensor that continuously and rapidly measures distance, closely monitoring the interval between itself and the receiver. Once this distance reaches a preset limit, whether too close or too far, the sensor immediately triggers a warning signal, i.e., a "limit number." This limit number is not merely a warning; it also carries emergency stop (emergency stop) data, which is rapidly transmitted to the receiver. Upon receiving this emergency signal, the receiver immediately implements corresponding safety measures, such as cutting off power or stopping mechanical movement, to prevent potential hazards. The entire process achieves instantaneous response and emergency control to distance changes, ensuring the safety of the system or operating environment.
[0017] It should be understood that both the foregoing general description and the following detailed description are exemplary and intended to provide further illustration of the claimed technology. Attached Figure Description

[0020] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.
[0021] First, combine Figs. 1-2 This invention describes a remote controller with secure distance communication according to an embodiment of the present invention, used for remote control, and with a wide range of applications.
[0022] like Figs. 1-2 As shown, a remote control with secure distance communication according to an embodiment of the present invention includes a distance sensor 6U1, a microcontroller, and a 485 transceiver chip 6U2.
[0023] Specifically, such asFigs. 1-2 As shown in the figure, the ranging sensor 6U1 is used for detecting the distance from the external receiver; the single-chip microcomputer is used for data processing; the 485 transceiver chip 6U2 is connected with the single-chip microcomputer and the ranging sensor 6U1, and is used for receiving operation requests, setting the ranging sensor 6U1 to fast automatic continuous measurement, and uploading the distance data of the continuous measurement of the ranging sensor 6U1 to the single-chip microcomputer.
[0024] Further, as shown in the figure, Fig. 2 The remote controller with safe distance communication of the embodiment of the utility model further contains: wiring terminal 1J2, wiring terminal 1J2 connects ranging sensor 6U1 and 485 transceiver chip 6U2.
[0025] Further, in the embodiment, the communication protocol of the ranging sensor 6U1 and the 485 transceiver chip 6U2 is Modbus RTU communication protocol.
[0026] Further, in the embodiment, the baud rate of the ranging sensor 6U1 is consistent with the baud rate of the serial port of the single-chip microcomputer, and the baud rate is 115200, which significantly improves the data transmission efficiency and system stability.
[0027] Further, the remote controller with safe distance communication of the embodiment of the utility model further contains: first capacitor 6C3, first diode 6D2, second capacitor 6C4 and second diode 6D3. One end of first capacitor 6C3 is connected with pin 11 of 485 transceiver chip 6U2; one end of first diode 6D2 is connected with pin 11 of 485 transceiver chip 6U2, and the other end of first diode 6D2 is connected with the other end of first capacitor 6C3 and then grounded; one end of second capacitor 6C4 is connected with pin 12 of 485 transceiver chip 6U2; one end of second diode 6D3 is connected with pin 12 of 485 transceiver chip 6U2, and the other end of second diode 6D3 is connected with the other end of first capacitor 6C3 and then grounded. Through the setting of first capacitor 6C3, first diode 6D2, second capacitor 6C4 and second diode 6D3, the protection circuit and the circuit stability can be improved.
[0028] As shown in the figure, Figs. 1-2As shown, the AB line of the distance sensor 6U1 is connected to the 485 transceiver chip 6U2 through the terminal 1J2, and the power supply voltage is 9V DC. When the remote controller is powered on, the default initialization program sends a frame request to the distance sensor 6U1, sets fast automatic continuous measurement, and configures the measurement frequency, such as 10Hz or 20Hz. After the single-chip microcomputer sends the instruction once, the distance sensor 6U1 will continuously measure the distance and report the data, which will occupy the RS485 bus. The data transmission distance parameter is in hexadecimal, and its unit in decimal is mm, for example, 4E 20 is converted to 20000mm (200m). After the single-chip microcomputer receives the data through the 485 chip, the program processes it.
[0029] Under normal circumstances, when the operator presses the emergency stop button, the remote controller sends emergency stop data to the receiver, and the receiver enters the emergency stop state, that is, all operations are invalid, and all functions stop.
[0030] When the distance between the remote controller and the receiver exceeds the limit value, the emergency stop data will also be sent. The distance sensor 6U1 is set to fast automatic continuous measurement, so that the distance sensor 6U1 sends automatic and continuous data to the single-chip microcomputer for data processing and judgment. When the distance reaches or exceeds the limit value, a judgment is made, and emergency stop data is sent to the receiver.
[0031] The above, with reference to Figs. 1-2 A remote controller with safe distance communication is described according to an embodiment of the present application. The sensor continuously and rapidly measures the distance and closely monitors the interval between the receiver. Once the distance reaches the preset limit, whether it is too close or too far, the sensor will immediately trigger a warning signal, i.e. "limit number". This limit number is not just a warning, but also carries emergency stop (emergency stop) data, which is quickly transmitted to the receiver. After receiving this emergency signal, the receiver will immediately execute the corresponding safety measures, such as cutting off the power supply, stopping mechanical movement, etc., to prevent potential dangerous situations. The whole process realizes immediate response and emergency control of distance changes, ensuring the safety of the system or operating environment.
