Description

Technical Field

[0001] The invention belongs to the technical field of measuring and mapping instruments and equipment, and in particular relates to a modular intelligent total station protective cover control system. Background Art

[0002] At present, the automatic total station, as a precision instrument integrating optical acquisition, mechanical movement, and electronic control, is widely used in the monitoring field of large-scale engineering construction such as building construction, bridges and tunnels, and railways, and has the following characteristics: 1. Unattended outdoor work. The working environment of the total station is relatively complex, ranging from uninhabited wilderness to densely populated towns and villages. It is impossible to send people to supervise the work at any time. 2. Fixed-point and scheduled work. The total station often does not work all the time, but runs at a specified time for a specified length of time to meet the needs of the project. 3. Expensive. As a precision instrument, the price of a total station is usually in the hundreds of thousands and needs to be properly kept.

[0003] Chinese patent application CN202011454121.5 discloses a total station protection device, which uses an MCU controller to realize the lifting and lowering of a foldable soft protective cover; Chinese patent application CN202210159852.X realizes the lifting and lowering of the protective cover body by connecting the motor forward and reversely; Chinese patent application CN202111658278.4 realizes the lifting and lowering of the protective cover by sending information instructions through the server. However, the above-mentioned devices all have the problem of single function, and only have simple opening and closing functions. Engineers can only passively use their existing functions and lack flexibility. Faced with complex urban and rural working environments, it is impossible to make intelligent responses and warnings to the approach of human bodies.

[0004] The traditional total station protective cover can no longer adapt to the complex monitoring environment and functional requirements, so it is necessary to provide a new modular intelligent total station protective cover control system to enhance the function of the protective cover. The present invention aims to provide an intelligent total station protective cover system to overcome the problems of the existing total station protective cover with single function and insufficient intelligence. Summary of the invention

[0005] To achieve the above purpose, the present invention provides a programmable modular intelligent total station protective cover control system, including a total station protective cover switch module, a human body radar sensing module, a speaker alarm module, an infrared remote control module and an industrial computer. The module is connected to the industrial computer via a USB cable, and is organically combined through programming on the industrial computer to achieve rich functions such as customized opening time, customized opening duration, alarm when the human body approaches and closes the protective cover, human body leaves and opens the protective cover, infrared control of the lifting of the protective cover, and email alarm. The modules are all independent.

[0006] The total station protective cover switch module includes an open cylindrical steel protective cover, a circular steel base, a DC motor push rod, a DC motor driver, and an MCU and a DC motor power supply. The cylindrical steel protective cover and the DC motor push rod are fixedly connected by bolts, and the circular steel base and the DC motor push rod are connected by bolts. The above three physical devices form the main body of the protective cover, and the up and down movement of the DC motor push rod realizes the opening and closing of the protective cover. The power cord of the DC motor push rod is connected to the DC motor driver, the DC motor driver is connected to the DC motor power supply, and the MCU is connected to the DC motor driver through a DuPont line. The above three physical devices form the opening and closing control subsystem of the protective cover.

[0007] The human body radar sensing module includes a human body sensing radar and an MCU. The human body sensing radar is connected to the MCU via a DuPont line. The above two physical devices realize the human body proximity distance monitoring subsystem.

[0008] The speaker alarm module includes a speaker power amplifier board, a speaker, and an MCU. The speaker power amplifier board is connected to the speaker through a DuPont line, and the speaker power amplifier board is connected to the MCU through a DuPont line. The above three physical devices realize the speaker alarm subsystem.

[0009] The infrared remote control module includes an infrared remote controller, an infrared receiver, and an MCU. The infrared receiver is connected to the MCU via a DuPont line. The above three physical devices realize the infrared remote control subsystem.

[0010] All the above modules are connected to the industrial computer via a USB cable, and the modules are coordinated through program control to achieve an organic combination of the modules, break through the physical intervals between the modules, and provide the protective cover with more abundant functions.

[0011] To realize the function of opening and closing the protective cover, the following steps are adopted: Step 1.1: Read the protection cover setting options.

[0012] Step 1.2: Determine the state of the protective cover. If it is on, close the protective cover and set the state of the protective cover to off, and proceed to Step 1.1; otherwise, proceed to the next step.

[0013] Step 1.3: Open the protective cover, set the status of the protective cover to on, and go to Step 1.1.

[0014] To implement the above-mentioned functions of opening and closing the custom time and custom duration, use the following steps: Step 2.1: Get the network time setting option and make a judgment. If the option is to turn on the network time, set the local time to the network time and proceed to the next step, otherwise go directly to the next step.

[0015] Step 2.2: Get the local time and determine the error between the current time and the set time. If the error is close enough, it is considered that the set time has been reached and proceed to the next step. Otherwise, continue to get the local time.

[0016] Step 2.3: Set the protection shield setting option to on, and wait for the customized protection shield opening time, then set the protection shield setting option to off and return to Step 2.2.

[0017] To realize the above functions of alarming when a human body approaches and closing the protective cover, and opening the protective cover and email alarming when a human body leaves, the following steps are adopted: Step 3.1: Read the radar setting options. If the radar alarm is turned on, go to the next step, otherwise read the radar setting options in a loop.

[0018] Step 3.2: Read the time and determine whether the current time is the working time when the protective cover is turned on. If it is not the working time, read the radar data to determine whether the sensed human body data is less than the set alarm distance. If it is, the speaker will alarm. After the alarm is completed, read the radar data again; if it is the working time, proceed to the next step.

[0019] Step 3.3: Read radar data and determine whether the sensed human body data is less than the set alarm distance. If so, proceed to Step 3.4. If so, read the email setting option. If the email setting option is turned on, send an alarm email to the given email address and proceed to Step 3.5. Otherwise, proceed directly to Step 3.5.

[0020] Step 3.4: Delay for three minutes and read the protection cover status. If the protection cover status is closed, set the protection cover setting option to open and return to Step 3.2, otherwise return directly to Step 3.2.

[0021] Step 3.5: Read the protection cover status. If the protection cover status is on, set the protection cover setting option to off and sound the speaker alarm; otherwise, sound the speaker alarm directly. Then return to Step 3.3.

[0022] To realize the above-mentioned infrared remote control function of controlling the lifting of the protective cover, the following steps are adopted: Step 4.1: Read infrared information Step 4.2: If the received infrared information is on, turn on the protective cover setting option and return to Step 4.1; otherwise, proceed to the next step.

[0023] Step 4.3: Close the protection cover setting option and enter Step 4.1. BRIEF DESCRIPTION OF THE DRAWINGS
