HBC remote control range of pump truck accessories Pump parts HBC remote control system is through the radio wave transmission of the operator's control instructions, so that the operator gets rid of the freedom of the tow cable, distance restrictions and inconvenience and other reasons, resulting in the use of wireless control to solve the above inconvenience, is a revolution in the field of industrial control, is now widely used in all walks of life. Although the control operation method of wireless and wired control is consistent, due to the particularity of radio, it is inevitable that radio waves will interfere with the use of wireless control, especially the industrial wireless remote control system for pump trucks, because of the particularity of the use of pump trucks, large mobility, the working area is not fixed, and the interference source is uncertain. The pump truck accessories HBC remote control system in the process of use will inevitably appear this and that signal interference, thus interrupting the operation. This requires us to correctly understand and fully understand, correctly distinguish the nature of interference, and how to reduce the inconvenience caused by interference. In order to be able to correctly analyze, it is necessary to understand some of the standards, specifications and scope of use of industrial wireless remote control systems, the following is a brief introduction to what is an industrial wireless remote control system from several aspects. First, the meaning of industrial wireless remote control system Industrial wireless remote control system is a new type of control mode in industrial production applications, which uses wireless transmission and remote control equipment operation. Due to the particularity and safety of remote control equipment, the appearance of industrial wireless remote control system, in order to avoid the confusion of wireless channels, countries have formulated corresponding regulations, industrial wireless remote control system, defined as micro-power radio transmission equipment. Second, the standard of industrial wireless remote control system According to European standards, the National Radio Administration has issued industrial wireless remote control system standards in line with domestic use as early as the last century. Its main technical indicators are: 1. The working frequency band is :418.950-419.275MHz, a total of 13 working frequency points 2, the interval between frequency points is :25KHz 3, the transmission power can not be greater than or equal to :10mw 4, the receiving sensitivity is greater than or equal to :20dB It is not difficult to see from the above standards that the industrial wireless remote control system is limited by national standards, the transmission power is weak, and the control distance is limited. In the normal working environment, if the antenna is installed reasonably, the remote control distance is generally about 100 meters. However, due to the different working environment and the different installation position of the antenna of the receiving system, its control distance may vary due to the environment. In addition; Because it is a micro-power transmitting and receiving equipment, it is easy to be interfered by other high-power wireless transmitting equipment, such as walkie-talkies, vehicle-borne and ship-borne communication radio, fixed radio and so on. Pump truck accessories HBC remote control system is produced in strict accordance with the standards of the Radio Administration of the People's Republic of China, each system has the above thirteen frequency points built in, the switch transmission system power supply once, and the automatic frequency hopping point once, a total of thirteen choices (more than the standard violates the regulations). That is to say, if in a radius of 200 meters, at the same time there are fourteen pump trucks in the remote control work, there will be two pump truck working frequency phase repeat, resulting in mutual interference!! In addition; Because our national radio management is more chaotic, smuggled various radio communication equipment can be seen everywhere, so in the use of wireless remote control, interference is inevitable (especially in the central cities and coastal areas of Guangdong Province). In order to reduce the interruption of operation due to wireless signal interference, we recommend that some corresponding measures be taken in use to reduce interference. 1. The antenna of the receiving system is installed in place. It is recommended to use a suction cup antenna when hitting a high level, and the antenna is introduced from the height of the car body, such as the top of the front. 2, in case of interference, the working frequency can be appropriately re-selected several times.
