BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a functional architecture block diagram of a data collection and control terminal device provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0010] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the following Figure 1 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0011] Figure 1 The data set control terminal device provided by the embodiment of the present invention is shown. For the convenience of description, only the part related to the embodiment of the present invention is shown, which is described in detail as follows:

[0012] A data control terminal device for polyurea spraying equipment, the device comprising an MCU module circuit, a 485 bus module, a CAN bus module, an analog quantity acquisition circuit and a switch quantity acquisition circuit respectively electrically connected to the polyurea spraying equipment; the 485 bus module, the CAN bus module, the analog quantity acquisition circuit and the switch quantity acquisition circuit are respectively electrically connected to the MCU module circuit;

[0013] The device also includes:

[0014] The equipment on / off detection circuit is electrically connected to the MCU module circuit and the main circuit of the polyurea spraying equipment respectively; it is used to detect the power-on status of the main circuit of the polyurea spraying equipment, and respond the analyzed on / off status of the polyurea spraying equipment to the MCU module circuit;

[0015] The automatic power switching circuit is electrically connected to the MCU module circuit, the battery module and the power supply of the polyurea spraying device respectively; when the polyurea spraying device is turned on, the device is powered by the power supply of the polyurea spraying device; when the polyurea spraying device is turned off, the device is powered by the battery module.

[0016] Specifically, by cooperating with the equipment power on / off detection circuit and the automatic power switching circuit, the power supply form of the data set control terminal device is selected based on the actual state of the polyurea spraying equipment, thereby ensuring that the data set control terminal device can work independently of the polyurea spraying equipment and also control the standby work, thereby saving power and extending the standby time.

[0017] Furthermore, the device also includes:

[0018] The 5G module circuit communicates remotely with the MCU module circuit and the background server; and is used to send the data collected by the device to the background server.

[0019] Furthermore, the device also includes:

[0020] The EEPROM storage module circuit is electrically connected to the MCU module circuit and the 5G module circuit respectively; it is used to store the data that failed to be sent successfully in the EEPROM storage module when the 5G module circuit fails to send data, and send the data in the EEPROM storage module to the background server when the communication returns to normal.

[0021] Specifically, by cooperating with the 5G module circuit and the EEPROM storage module circuit, it is possible to avoid data errors caused by forcibly exchanging data with the background server when the network environment is not good. The data temporary storage function of the EEPROM storage module allows for more and better options for the time to send data and the network environment.

[0022] Furthermore, the device also includes:

[0023] The cabinet door opening and closing detection circuit is electrically connected to the MCU module circuit and the cabinet door sensor of the polyurea spraying equipment respectively; and is used to collect the opening and closing information of the cabinet door of the polyurea spraying equipment.

[0025] The temperature and humidity acquisition circuit is electrically connected to the MCU module circuit and the environmental temperature and humidity sensor respectively; and is used to collect the temperature and humidity information of the environment.

[0026] Furthermore, the MCU module circuit also receives remote control instructions and remote upgrade data packets issued by the background server, which are used to remotely control the polyurea spraying equipment and remotely upgrade the program of the equipment, so that the operating procedures of the polyurea spraying equipment and the data control terminal device are scalable, which is convenient for the improvement of subsequent functions.

[0027] Furthermore, the switch quantity acquisition circuit is used to collect the core data of the polyurea spraying equipment during operation and the lithium battery voltage data of the battery module in real time; the core data are pressure, temperature and number of cycles.

[0028] Furthermore, the device power on / off detection circuit uses optocoupler isolation.

[0029] Furthermore, the cabinet door opening and closing detection circuit adopts optical coupling isolation.

[0030] Furthermore, the switch quantity acquisition circuit uses optocoupler isolation.

[0031] Specifically, the sensor used in the data collection and control terminal device is isolated by optical coupling, which can improve the accuracy and security of data collection.

[0032] The embodiment of the present invention performs remote intelligent monitoring of the polyurea spraying equipment by adding a data collection control terminal device, and at the same time, the data collection control terminal maintains a power-supply standby state regardless of whether the polyurea spraying equipment is turned on or not. Furthermore, the data collection control terminal enters a dormant state after the data reporting is completed, reducing its own power consumption and increasing the standby time. In addition, the data stored by adding an EEPROM storage module can be resent to the server after the network environment is restored to prevent data loss. The sensor adopts optical coupling isolation, and the data collection is accurate and safe.
