In the present embodiment, a wireless sensor network is configured using stationary sensors. The central control host computer obtains the intrusion signal through the wireless sensor network.
And S200, judging whether an intruder exists or not based on the intrusion signal.
The central control host judges whether an intruder exists or not by judging whether the intrusion signal transmitted by the wireless sensor network is received or not.
Specifically, the wireless sensor network comprises a plurality of infrared sensors and a plurality of aggregation nodes, wherein one aggregation node corresponds to the plurality of infrared sensors;
the step of judging whether an intruder exists or not based on the intrusion signal comprises the following steps:
s210, judging whether the sink node receives an intrusion signal monitored by the infrared sensor.
In the embodiment, the sink node adopts a ZigBee coordinator, a plurality of infrared sensors are deployed in a monitoring area and form a wireless network, namely the ZigBee network, in a self-organizing manner, data monitored by the infrared sensors reach the sink node through wireless transmission, the sink node is used for transmitting the data monitored by the infrared sensors to a central control host, and specifically, the sink node transmits the data monitored by the infrared sensors to the central control host through a serial communication interface.
In specific implementation, the infrared sensors are deployed on two sides of the asphalt concrete pavement, one or more infrared sensors are deployed at preset intervals, and meanwhile, communication connection needs to be guaranteed among the infrared sensors. The plurality of infrared sensors correspond to one sink node, and the sink node transmits signals monitored by the infrared sensors to the central control host.

In specific implementation, the temperature of the road surface which is just compacted is usually about 80 ℃, and the temperature is high, so that safety risk is caused to the invading human or animals, and therefore, a first temperature threshold value is set for monitoring the safety condition of the invador. If the first temperature information is higher than the first temperature threshold value, it is indicated that the temperature of the asphalt concrete pavement brings safety risk to an intruder at the moment, and meanwhile, the asphalt is not solidified, so that the intruder may damage the pavement.

If an intruder occurs and the temperature of the asphalt concrete pavement is higher than a first temperature threshold value when the intruder intrudes, the buzzer is controlled to give an alarm, a primary alarm signal is sent out and displayed on the display screen for reminding a worker to treat as soon as possible and checking the safety condition of the intruder and the condition of the asphalt concrete pavement at the intrusion site of the intruder. For example, if the first temperature threshold is set to 75 degrees celsius, and if there is an intruder, the temperature of the asphalt concrete pavement, that is, the first temperature information, is higher than 75 degrees celsius, the central control host sends a primary alarm signal and controls the buzzer to alarm.

This algorithm is implemented in detail and therefore is not described in detail herein.
The step of judging that the first camera is damaged and has a fault comprises the following steps:
