The robot program control circuit randomly controls the various audio signals (10) through the circuit. It has the characteristics of simple circuit, convenient operation and low cost.
As shown in the figure, the program programmed in the tape is input from the Vi end. lC1 (555) and R6, C3 form a monostable trigger circuit. Each time an audio signal is input to the V1 terminal, the ICl trigger is set once to form td=1.1R6C3, and a positive polarity pulse of about 0.6 seconds is sent to the CP end of the IC2. 1C2 uses 1/2CD4013 (D flip-flop), which is connected to flip-type trigger, that is, every time a positive pulse is sent, the output state of Q2 changes once. The output of IC2 is divided into two ways, one way is added to VT10 which is used as electronic switch tube, and the power is turned on for each relay; the other is sent to IC3. IC3 is a four-input NAND gate, which uses 1/2CD4011 to form pulse keying multi-harmonic The oscillator has an oscillation period of T = 2.2R6C5, and the illustrated parameter is about 1 second. It generates an oscillating signal as a clock pulse for IC4. IC4 uses a decimal counter/pulse splitter. Under the action of the clock CP, its output terminals Y0~Y9 sequentially appear high-level pulses with a pulse width of T. VT0~VT9 are turned on in turn, the corresponding J0~J9 is controlled to be connected, and the external solenoid valve or the follower mechanism is controlled to control the ten actions of the manipulator respectively. The suction of 10 J can be arranged or selected according to the needs of the work.
It is worth mentioning that although this circuit can only control 10 actions, if necessary, using the carry pulse of the 1C4 Qco terminal (12 feet), you can cascade 2 or several CD4017 to expand the control range.
An Indoor Access Point is a device for wireless local area networks (WLAN) that provides wireless network coverage and connectivity. It can connect to a wired network and transmit data via a wireless signal, allowing users to connect to the network wirelessly within coverage.
Indoor access points come in a variety of different types and specifications to suit different scenarios and needs. Here are some common types of indoor access points:
1. Single Band Access Point: A single band access point operates in the 2.4GHz band and typically provides a maximum transfer rate of 300Mbps. This type of access point is suitable for small office or home networks because the 2.4GHz band has better penetration and coverage, but a relatively low transfer rate.
2. Dual Band Access Point: The dual band access point supports both 2.4GHz and 5GHz bands, providing higher transmission rates and better performance. The 5GHz band has more interference free channels than the 2.4GHz band, which can provide faster speeds and more stable connections. Dual-frequency access points are suitable for medium sized offices, malls or hotels.
3. Lightweight Access Point: A lightweight access point is a wireless network device that needs to be used with a network controller. Lightweight access points do not have independent management functions themselves, but are centrally managed and configured via a network controller. This type of access point is suitable for large enterprises or organizations to enable centralized management and monitoring of the entire network.
4. Standalone Access Point: A standalone access point is a standalone device that has its own management and configuration functions and does not require additional network controllers. This type of access point is suitable for small businesses or individual users and can provide a simple and easy-to-use wireless networking solution.
5. Scalable Access Point: A scalable access point is a device that can scale on demand, increasing or decreasing the number of access points based on network demand. This type of access point is suitable for places that require flexible scaling, such as large office buildings, schools, or hospitals.
In addition to the types listed above, there are some special purpose indoor access points, such as:
1. Wall-mounted Access Point: A wall-mounted access point can be plugged directly into a Wall power outlet without the need for an additional power cord. This type of access point is suitable for home networks or small offices and can provide easy installation and use.
2. Integrated Antenna Access Point: The antenna of the antenna access point is integrated into the device, and no additional antenna installation is required. This type of access point is suitable for sites that require simple installation and a nice look.
3. Multiple Antenna Access Point: Multiple antenna access points can achieve better signal coverage and performance through multiple antennas. This type of access point is suitable for large venues or high-density user environments, such as conference rooms, stadiums or airports.
To sum up, there are many different types and specifications of indoor access points, which can be selected according to different scenarios and needs. Whether it's a small office, home network or a large enterprise, you can achieve convenient wireless network coverage and connectivity through indoor access points.
