Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Example one

Referring to fig. 1-3, a monitored control system based on beidou navigation system, including control module, beidou system, receiving module, central processing unit, power module, adjusting module, emission module and camera, control module is connected with beidou system, beidou system is connected with receiving module, receiving module is connected with central processing unit, central processing unit is connected with power module, power module is connected with adjusting module, power module and adjusting module all are connected with emission module, emission module and control module are connected.

In the invention, the control module is connected with the Beidou system through signals, and the transmitting module is connected with the control module through signals.

In the invention, the communication between the Beidou system and the receiving module is realized through local hardware communication, such as serial ports, spi, sdio and other modes.

In the invention, the power supply module controls the opening and closing of the camera and the adjusting module.

In the invention, the external of the central processing unit is connected with a timer, and the timer is set with an opening threshold value and a closing threshold value.

The power module comprises a series relay, a router, a contactor and a storage battery, wherein the series relay is respectively connected with the router and the contactor, the series relay is used for receiving data of the router and converting the data into switching value signals, so that the switch of the camera is controlled through the contactor, and the storage battery is respectively connected with the series relay and the router and provides electric energy for the series relay and the router.

In the invention, the infrared sensor is fixedly connected to the outside of the camera.

The working principle is as follows: this monitored control system is in standby state at ordinary times, and when beidou system received the SMS instruction that control module sent, began to parse the instruction content, according to the instruction content again, set up the control task, send the task to monitored control system's receiving module again, receiving module gives central processing unit with received data transmission, and central processing unit receives the data after, begins to carry out following step:

step 1, judging whether a starting instruction is received or not, if the starting instruction is received, starting a power supply module, if the starting instruction is not received, judging whether an infrared sensor senses infrared rays or not, if the infrared sensor senses the infrared rays, starting the power supply module, if the infrared sensor does not sense the infrared rays, judging whether a timer starting threshold value is reached or not, if the timer starting threshold value is reached, starting the power supply module, and if the timer starting threshold value is not reached, returning to the step 1;

step 2, if the power module is started in the step 1, namely when the camera starts to work, the central processing unit starts to judge whether a closing instruction is received, if the closing instruction is received, the power module is closed, if the closing instruction is not received, whether a timer closing threshold value is reached is judged, if the timer closing threshold value is reached, the power module is closed, and if the timer closing threshold value is not reached, the step 2 is returned;

and 3, returning to the step 1 if the power supply module is turned off in the step 2, namely the camera stops working.

Meanwhile, the central processing unit starts to judge whether angle adjustment is needed, if the angle adjustment is not needed, the picture shot by the camera is directly sent to the control module through the transmitting module in real time, if the angle adjustment is needed, the adjusting module is controlled to adjust the angle of the camera, and after the angle adjustment is completed, the picture shot by the camera is sent to the control module through the transmitting module in real time.
