[0024] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0026] The industrial wireless remote control system for starting up by infrared rays provided by the utility model comprises a start button for triggering a start operation instruction; a function operation switch for triggering a corresponding function signal instruction; a remote control transmitting system comprising a transmitter chip and a transmitter mainboard, wherein the transmitter chip is integrated and arranged on the transmitter mainboard, and the transmitter chip is used to generate a remote control signal; an infrared transmitting circuit connected to the transmitter mainboard and used to control the emission of infrared light signals; an infrared light emitting diode connected to the infrared transmitting circuit and used to convert the remote control signal into an infrared light signal; a high-frequency transmitting module connected to the transmitter mainboard and used to generate a radio signal according to a signal triggered by the function operation switch; a remote control receiving system comprising an infrared receiving module and a high-frequency receiving module, which are respectively connected to the receiver chip and used to receive the transmitted infrared light signal and radio signal; the receiver chip is arranged on the receiver mainboard, and the receiver mainboard is used to transmit the received infrared light signal and radio signal to the remote control system starting unit or the mechanism action signal output unit respectively.

[0027] For example, the infrared transmitting circuit may be integrated on the transmitter mainboard, or may be an independent circuit structure connected to the transmitter mainboard, which is not limited in this embodiment.

[0028] For details, please refer to Figure 1 and Figure 2 ,The infrared power-on function of the remote control system is mainly composed of a transmitter, an infrared receiving module and a receiver.

[0029] The transmitter is equipped with infrared light-emitting diodes, start buttons and other control switches. The transmitter mainly contains transmitter chips, transmitter motherboards, high-frequency transmitter modules and infrared transmitter circuits. When the remote control system is in the off state, if you want to activate the transmitter, you must first take the transmitter within 20 meters of the infrared receiving module so that the operator can visually see the infrared receiving module, and there is no obstruction between the transmitter and the infrared receiving module. Then, after aligning the infrared light-emitting diode with the infrared receiving module as much as possible, press the start button, and the start command will be recognized by the control chip program to generate the required command signal. The transmitter motherboard encodes and modulates the command signal, and after the infrared transmitting circuit power is amplified, the infrared light-emitting diode emits the modulated command code signal in the form of infrared rays.

[0030] The receiving part consists of an infrared receiving module and a receiver. The receiver is generally installed in the electrical cabinet of the equipment. The infrared receiving module is connected to the receiver through a cable. The length of the cable can be configured arbitrarily so that the infrared receiving module can be installed in a position that is easy for the operator to see.

[0031] When the receiving system is powered on, the infrared receiving module can receive infrared signals, receive the infrared coded signals sent by the transmitter, convert them into corresponding electrical signals, and transmit them to the receiver through cables. The receiver is mainly composed of a receiver chip, a receiver motherboard, and an output circuit. After the receiving control chip receives the electrical signal from the infrared receiving module, it is decoded and demodulated by the demodulation circuit of the receiver motherboard, and finally the operation control of the start command is realized, and the remote control system starts normally.

[0032] The industrial wireless remote control system provided by the utility model, which is turned on by infrared rays, has not only an infrared start function, but also a radio wave transmission function. After completing the normal infrared start remote control, the operator can operate other mechanism actions on the transmitter, such as rocker commands, knob switch commands, etc., which are transmitted by radio wave transmission. The radio waves are transmitted through the high-frequency transmitting module installed in the transmitter and the high-frequency receiving module in the receiver. The transmission distance of the radio waves is long, so the operator can leave the limit within 20 meters and can usually operate at a distance of 100-150 meters.

[0033] The transmitter and receiver of the industrial wireless remote control system provided by the utility model have both infrared transmission function and radio wave transmission function. The remote control system can only be started through the infrared transmission function, forcing the operator to observe the on-site situation closely before operating the equipment, thus ensuring on-site safety.

[0034] In order to ensure that the infrared signal emitted by the transmitter has strong directionality, the transmitter provided in this embodiment is provided with a light converging device in the infrared emission area to control the infrared radiation range within 30°. The light converging device can be a combination of a convex lens and a concave lens similar to a telescope structure, or it can be a concave mirror, which is not limited in this embodiment. On the other hand, in order to ensure that the transmission distance of the infrared signal is within 20 meters, the remote control transmission system provided in this embodiment includes a power regulating device, which is connected to the infrared emission circuit and can manually adjust the power of the infrared emission circuit, thereby adjusting the transmission distance of the infrared signal.

[0035] The utility model has both radio wave transmission function and infrared transmission function. The infrared transmission function is only used to start the remote control system. The operator can only activate the radio system when there is an infrared connection between the transmitter and the receiver. The maximum distance of infrared transmission is 20 meters, and the radiation angle of infrared is about 30°. Therefore, during the activation process, the operator must intentionally point the transmitter in the direction of the receiver to trigger the activation system.

[0036] The utility model utilizes the characteristics of infrared transmission distance and directional radiation angle to limit the start-up distance and direction of the remote control system, ensuring that the operator can only start the remote control when the transmitter is within 20 meters and the receiver is pointed. This ensures that the operator observes the on-site environment before starting the equipment, avoids dangerous situations caused by accidental activation of the wireless remote control, and protects the operator and other people near the operated equipment.

The utility model is intended to cover any variation, use or adaptation of the utility model, which follows the general principles of the utility model and includes common knowledge or conventional technical means in the technical field not disclosed in the utility model.
