Detailed ways

Example 1

As shown in Fig. 1, a kind of intelligent electronic guardrail system, it comprises the sensing device that is positioned at around the power maintenance area, and described sensing device sends sensing signal to main control circuit through wireless module I3; Described main control circuit includes main control circuit The control circuit board and the wireless module II4 connected with it, the sound and light alarm circuit, the serial port conversion circuit and the relay control circuit. In this way, when someone enters the defense area, the induction device will send an induction signal to the main control circuit at this time. After the main control circuit receives the signal, it will immediately control the circuit to perform protection actions (corresponding to the relay work and alarm), so as to avoid interference in power maintenance in time. cause unnecessary losses.

Wherein, both the wireless module I and the wireless module II are zigbee wireless transceiver modules. Zigbee is a low-power personal area network protocol based on the IEEE802.15.4 standard. The technology specified under this agreement is a short-distance, low-power wireless communication technology. It is characterized by close range, low complexity, self-organization, low power consumption, low data rate, and low cost. It is mainly suitable for the fields of automatic control and remote control, and can be embedded in various devices. In short, ZigBee is a cheap, low-power short-range wireless networking communication technology. Its data rate is relatively low, only 250Kb/S in the 2.4GHZ frequency band, and this is only the rate on the link. Excluding the consumption of channel contention response and retransmission, the rate that can really be used by applications may be less than 100Kb/S. And the remaining rate may be divided by multiple adjacent nodes and multiple applications of the same node, so it is not suitable for things like video. But it is suitable for the sensing and control required by the utility model.

As shown in Figure 2, in this embodiment, the sensing devices are two sets of infrared transmitters 1 and two sets of infrared receivers 2, wherein the two sets of infrared transmitters 1 are arranged diagonally, and the two sets of infrared receivers 2 are arranged diagonally, And a wireless module I3 is set in each group of infrared receivers 2 .

It can be seen from the figure that the infrared radiation distance can reach 100 meters, and the wireless transmission can reach 1.6 kilometers, which greatly improves the portability and flexibility.
