电动卷闸门� ？仄髋渲靡�
常用的电动门� ？叵低骋话惴址⑸浜徒邮樟礁霾糠� 。
The commonly used electric door remote control system is generally divided into two parts: transmitting and receiving.
(1)发射部分
(1) Launch part
分为� ？仄骱头⑸淠 ？�，� ？仄魇亲魑桓稣炊懒⑹褂�;而� ？啬 ？樵诘缏分械币桓鲈词褂�，凭据其引脚界说进行应用，使用� ？啬 ？榈挠攀圃谟诳梢院陀τ玫缏诽煲挛薹斓牧印⑻寤 ⒌汀⑽锞∑溆�，但使用者必须真正明白电路原理，不然照旧用� ？仄骼吹谋愕� 。
It is divided into remote controller and transmitting module. The remote controller is used independently as a whole machine; The remote control module is used as a component in the circuit and is applied according to its pin definition. The advantage of using the remote control module is that it can be seamlessly connected with the application circuit, small volume, low price and make the best use of everything. However, the user must really understand the circuit principle. Otherwise, it is convenient to use the remote control.
(2)接收部分
(2) Receiving part
分为超外差与超再生接收方法，超再生解调电路也称超再生检波电路，它实际上是事情在间歇振荡状态下的再生检波电路 。超外差式解调电路与超外差收音机相同，它是设置一本机振荡电路爆发振荡信号，与接收到的载频信号混频后，获得中频(一般为465kHz)信号，经中频放大和检波，解调出数据信号 。由于载频频率是牢固的，所以其电路要比收音机简简单些 。超外差式的接收器稳定、灵敏度高、抗滋扰能力也相对较好;超再生式的接收器体积小、自制 。
Super regenerative demodulation circuit is also called super regenerative detection circuit. It is actually a regenerative detection circuit working in intermittent oscillation state. Superheterodyne demodulation circuit is the same as superheterodyne radio. It is equipped with a local oscillation circuit to generate oscillation signal. After mixing with the received carrier frequency signal, the intermediate frequency (generally 465kHZ) signal is obtained. After intermediate frequency amplification and detection, the data signal is demodulated. Because the carrier frequency is fixed, its circuit is simpler than that of a radio. The superheterodyne receiver has the advantages of stability, high sensitivity and relatively good anti-interference ability; Super regenerative receiver is small and cheap.
影响无线电式电动卷闸门� ？仄饕 ？鼐嗬氲囊蛩兀�
Factors affecting the remote control distance of radio electric rolling gate remote controller:
a.阻挡，目前使用的无线� ？仄魇褂没ǖ腢HF频段，以直线流传，中间若有墙壁阻挡将折损� ？鼐嗬�，如果是钢筋混泥土的墙壁，由于导体对电波的吸收作用，影响愈甚;
a. Blocking: the currently used wireless remote controller uses the UHF frequency band specified by the state and propagates in a straight line. If there is a wall blocking in the middle, the remote control distance will be damaged. If it is a reinforced concrete wall, it will be even more affected due to the absorption of electric waves by conductors;
b.发射功率，发射功率大则距离远，但耗电大，容易爆发滋扰;
b. Transmission power: large transmission power means long distance, but it consumes a lot of power and is prone to interference;
c.接收灵敏度，接收器的接收灵敏度提高，� ？鼐嗬朐龃�，但容易受滋扰造成误动或失控;
c. Receiving sensitivity: the receiving sensitivity of the receiver is improved, and the remote control distance is increased, but it is easy to be disturbed, resulting in misoperation or out of control;
d.天线，接纳直线型天线，并且相互平行，� ？鼐嗬朐�，但占据空间大，在使用中把天线拉长、拉直可增加� ？鼐嗬�;
d. The antenna adopts linear antennas, which are parallel to each other and have a long remote control distance, but occupy a large space. Lengthening and straightening the antenna in use can increase the remote control distance;
e.高度，天线越高，� ？鼐嗬朐皆�，但受客观条件限制 。
e. Height, the higher the antenna, the farther the remote control distance, but it is limited by objective conditions.
电动卷闸门� ？仄骷际跣阅埽�
Technical performance of remote controller for electric rolling gate:
1、事情电压：� ？睾蠥C220V，� ？仄鱀C12V(23A型电池) 。
1. Working voltage: remote control box AC220V, remote controller DC12V (23a battery).
2、负载功率：≤200VA 。
2. Load power: ≤ 200va.
3、� ？鼐嗬耄�≤100米 。
3. Remote control distance: ≤ 100m.
4、� ？乩嘈停何奁蛐�，可穿墙越壁 。
4. Remote control type: non directional, can pass through the wall.
5、� ？胤椒ǎ�315MHz 6万组编码，产品之间互不滋扰 。
5. Remote control mode: 315MHz 60000 groups of codes, and products do not interfere with each other.
6、外形尺寸：� ？睾�130×85×35mm，� ？仄�60×40×13mm 。
6. Overall dimension: remote control box 130 × eighty-five × 35mm, remote control 60 × forty × 13mm 。
电动卷闸门� ？仄魇虑槠德视氡嗦耄�
Working frequency and code of remote controller of electric rolling gate:
电动门� ？爻Ｓ玫脑夭ㄆ德饰�315mHz或者433mHz，� ？仄魇褂玫氖腔ǖ目牌刀�，在这一频段内，发射功率小于10mW、笼罩规模小于100m或不凌驾本单位规模的，可以不必经过“无线电治理委员会”审批而自由使用 。
The common carrier frequency of electric door remote control is 315MHz or 433MHz. The remote controller uses the open frequency band specified by the state. In this frequency band, if the transmission power is less than 10MW, the coverage is less than 100m or does not exceed the scope of the unit, it can be used freely without the approval of the "Radio Regulatory Commission".
