The external power supply and IO devices are limited.

[0038] In order to solve the above problems, Figure 1 As shown, the present application provides an expandable universal controller 100, which includes a main controller 110, an expandable wireless module 120, and an expandable digital quantity module 130, including:

UART, USB, I2C, and IO signals are arranged in the second expansion connector to achieve interface cascading with the main controller 110.

[0042] It should be noted that, according to actual needs, an antenna SMA connector 134 can be provided on the upper side of the expandable wireless module 130 , and the antenna connector here can be fixed or detachable, and this document does not impose any specific restrictions on this.

[0043] The main controller 110 is used to receive the wireless signal of the expandable wireless module transmission 120, generate a wireless selection instruction, and send it to the expandable wireless module 120. The expandable wireless module includes Bluetooth, Star Flash, 4G or 5G, integrated GNSS, LoRa, GigBee, and sensors.

[0044] like Figure 3As shown, the expandable universal controller 100 of the present application also includes an expandable analog module 140, which includes a third concave slot 141 set at the upper and lower ends of the left side shell of the expandable analog module, a third expansion connector plug end 142 and a third positioning column pin head 143 set on the left side shell of the expandable analog module 140; the main controller 110 and the expandable analog module 140 are mutually engaged and slid in through the third concave slot 141 and the first convex slot 111, and the third positioning column pin head 143 and the first positioning column pin tail 113 are mutually engaged with each other for installation in place; the first expansion connector socket end 112 and the third expansion connector plug end 142 are mutually plugged in for realizing the expansion of the expandable analog module type, and the main controller 110 is used to receive the analog signal transmitted by the expandable analog module 140, generate control instructions, and send them to the expandable analog module 140. A CAN bus is set inside the third expansion connector, and the expandable analog module 140 and the main controller 110 are cascaded through the CAN bus.

[0045] The main controller 110 is used to receive the analog signal transmitted by the expandable analog module 140, generate a control instruction, and send it to the expandable analog module 140. The expandable analog module includes a current input (AI), a current output (AO), and a voltage output (VO).

[0046] It should be noted that the structure of the concave chute in this application, such as Figure 4 As shown, all are the concave slide groove structures shown in 401, and the convex slide groove structures in this application are all the convex slide groove structures shown in 402.

[0047] The expandable wireless module 110 of the present application is also provided with a wireless module type detection module 150, which is mainly used to identify the type of the expandable wireless module 130. Figure 5 As shown (the main module is the main controller 110 in this application), the wireless module type detection module 150 has 8 channels, each channel can be configured to a high level or a low level through an external level, and the main controller 110 reads the level of each channel of the wireless module type detection module through the I2C bus. There are a total of 16 combinations, that is, 16 types of wireless modules can be connected. Figure 6As shown, the schematic diagram of the device type detection module is as follows, A0, A1, A2 are I2C address configuration pins, VCC and GND are power supply pins, SC0~SC7 are 8 channels, each channel can be configured to high level or low level through external level, and the I2C bus can read the level of each channel as the specific type of the expandable wireless module, which can achieve 16 combinations. In other words, the channel level corresponding to the expandable wireless module 130 is pre-set, and after the wireless expandable module is inserted, the corresponding level channel will change, and then the type of the expandable wireless module 130 is confirmed according to the channel with changed level, and then when the main controller 110 queries and reads, the confirmation result of the expandable wireless module type is returned to the main controller 110 through the I2C bus.

[0048] In addition, the expandable digital quantity module 120 of the present application is also provided with a first automatic slot detection module 160, and the expandable analog quantity module 140 is also provided with a second automatic slot detection module 170. The first automatic slot detection module 160 is used to detect the slot of the expandable digital quantity module, and the second automatic slot detection module 170 is used to detect the slot of the expandable analog quantity module.

[0049] Since the first automatic slot detection module and the second automatic slot detection module have the same principle, a detailed introduction to the first automatic slot detection module is sufficient. Figure 7 As shown, Figure 7 The main module in the embodiment is the main controller 110 of the present application, and the submodule is the expandable analog digital module 120 or the expandable analog module 140 of the present application. Figure 7It can be seen that the detection scheme in the present application only occupies 2 PIN pin resources. When only one sub-module is connected, since the default control signal of the control module 1 on the sub-module 1 is pulled high by default, the controller module 1 is turned on to the ground, and the resistor forms a loop with the ground, so that the ADC power supply on the CPU module and the resistor on the sub-module 1 and the control module 1 form a loop. The sub-module processor collects the voltage on the resistor of the sub-module through the ADC, and transmits the voltage value to the processor on the CPU module through the CAN bus, and judges it as slot 1. Similarly, when two sub-modules are connected, the sub-module 2 pulls down the control module 1 in the previous sub-module through the control signal, so that the control module 1 is cut off, and the resistor on the sub-module 2 is connected in series with the resistor of the previous sub-module 1. At the same time, the control of the sub-module 2 The controller signal 2 of the control module 2 is pulled high by default, and the control module 2 is connected to the ground, forming a loop. Therefore, the ADC voltage on the CPU module is divided by two resistors, and the voltage values ​​collected by the two sub-module ADCs are different. The second sub-module is judged as slot 2, and so on. When N sub-modules are connected, it is equivalent to the ADC power supply on the main module CPU being connected in series with N resistors. The voltage is divided into N equal parts, and the voltage collected by the sub-module ADC on each level of sub-module is different. The farther away from the CPU module, the lower the collected voltage. The processor on the CPU module sorts through the software algorithm to clarify the different sub-modules and the specific slots connected. No human intervention is required. Moreover, the sub-modules can be installed in a certain position at will, thereby achieving the purpose of automatic slot detection.

[0050] It should be noted that in the application of actual scenarios, the present application can determine, based on actual needs, whether the expandable digital module 130 or the expandable analog module 140 is connected to the right side of the main controller 110. This document does not make specific restrictions on this, and the setting of the expandable connector socket and plug in the present application can be set according to actual needs, and is not the fixed setting structure mentioned above in the present application.

[0051] The expandable universal controller of the present application realizes flexible configuration and installation of interface modules by setting different slide grooves and positioning pins on the main controller, connects more abundant peripheral modules, meets the flexible use requirements of multiple scenarios, solves the problems of the large number and variety of devices in the scenarios, supports wired and wireless networking, and is flexible and convenient to use.

[0052] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
