為了提高電動操作的自動化水平和,減少操作員的勞動強度和強電磁場操作員的人身威脅,從80年代,許多已經先后進行了實況機器人的研究和開發工作,如日本、西班牙、美國、加拿大、法國和其他進行的研究和開發工作生活的機器人。2014年，也完成了高壓帶電工作機器人產品原型的開發。電動扳手是高壓帶電作業機器人的專用工具，其主要功能是安裝和拆卸高壓帶電作業絕緣子等需要維護的連接工具。摘要為了滿足高壓電動作業機器人應用的需要，研制了一種以DSP為主控制器的新型遙控沖擊電動扳手，能夠滿足高壓帶電作業的要求。
In order to improve the automation level and safety of electric operation and reduce the labor intensity of operators and the personal threat of operators in strong electromagnetic fields, many countries have carried out research and development of real-time robots since the 1980s, such as Japan, Spain, the United States, Canada, France and other countries. Robots working and living. In 2014, China also completed the prototype development of high-voltage live working robots. Electric wrench is a special tool for high-voltage live-working robot. Its main function is to install and disassemble insulators for high-voltage live-working and other connecting tools that need to be maintained. In order to meet the needs of the application of high-voltage electric working robot, a new type of remote control impact electric wrench with DSP as the main controller is developed, which can meet the requirements of high-voltage live working.

The switch of the electric wrench is controlled by the wireless remote control receiving module. With over-current and over-voltage automatic protection circuit, the performance is reliable. The speed of the driving wrench is more than three times that of the ordinary electric wrench, and it stops automatically when the preset torque is reached. Reducer is adopted to reduce speed, which is stable and reliable.

3.無線收發模塊
3. Wireless transceiver module
超外差接收機以其電路簡單、成本低等優點得到了廣泛的應用。超外差接收機雖高，但溫度適應性強，接收靈敏度高，運行穩定可靠，抗干擾能力強。因此，選用抗干擾能力強的無線接收模塊。
Super heterodyne receiver has been widely used because of its simple circuit and low cost. Although the price of superheterodyne receiver is high, it has strong temperature adaptability, high receiving sensitivity, stable and reliable operation, and strong anti-interference ability. Therefore, the wireless receiving module with strong anti-jamming ability is chosen.
帶有接收模塊的遠程控制。遙控信號傳輸距離300-500米。各鍵的功能如表所示:
Remote control with receiving module. The transmission distance of remote control signal is 300-500 meters. The functions of each key are shown in the table.
4. 電源電路設計
4. Power Circuit Design
為了實現電路的可靠性，對電路采取了以下措施:
In order to achieve the reliability of the circuit, the following measures have been taken for the circuit:
1)抗電磁干擾
1) Anti-EMI
電磁干擾必須包括電磁干擾源、電磁干擾傳輸方式和接收電磁干擾的應答器三個要素。
Electromagnetic interference must include three elements: the source of electromagnetic interference, the transmission mode of electromagnetic interference and the responder receiving electromagnetic interference.
2)過電流保護
2) Overcurrent protection
為了防止控制部分和點擊驅動部分短路，在前序電路中添加類似F1和F2的自恢復報告。自恢復熔斷器是一種新型的聚合物熔斷器，當電流低于額定值時，其電阻僅為歐姆的十分之一。當電路足夠大時，它的阻值迅速上升，產生熱量，阻值越高，就越阻礙電源電流。
In order to prevent short-circuit of control part and click driver part, self-recovery report similar to F1 and F2 is added to the preamble circuit. Self-recovery fuse is a new type of polymer fuse. When the current is lower than the rated value, its resistance is only one tenth of ohm. When the circuit is large enough, its resistance value rises rapidly, generating heat. The higher the resistance value, the more obstructing the power supply current.
3)過電壓保護裝置
3) Overvoltage Protection Device
如圖所示，為了防止后續電路過電壓，在電源電路中分別添加抑制二極管VTS1和VTS2。抑制二極管可以看作是兩個齊納二極管并聯和反向，當電流兩端的電壓高于一定額定值時進行傳導。它的特點是瞬間通過數十萬安培的電流。
As shown in the figure, in order to prevent the subsequent circuit from overvoltage, suppression diodes VTS1 and VTS2 are added to the power supply circuit respectively. Suppression diodes can be seen as two Zener diodes in parallel and reverse, conducting when the voltage at both ends of the current is higher than a certain rating. It is characterized by instantaneous passage of hundreds of thousands of amperes of current.
4)反接保護
4) Reverse connection protection
為了保護二次電源在輸入電路反向連接時不受損壞，在輸入端增加了反向連接保護電路。當二極管打開時，熔斷器電阻增加，電流被抑制。起極保護作用。
In order to protect the secondary power supply from damage in the reverse connection of the input circuit, a reverse connection protection circuit is added at the input end. When the diode is turned on, the fuse resistance increases and the current is suppressed. It plays an extremely protective role.
