Description

Technical Field

[0001] The utility model belongs to the technical field of equipment intelligence, and in particular relates to a remote control circuit for simulating a human button-clicking operation. Background Art

[0002] At present, many control systems, such as the up and down movement of museum display cabinet motors, or the opening and closing of cabinet door motors, or the air-conditioning controllers on refrigerated trucks, generally use control panels with physical buttons to realize human-computer interaction functions. This has a relatively large limitation, that is, it requires manual operation. If there is an application site that needs to control the motor to rise a little, and the workers are not on site, then the operation can only be performed after the workers arrive on site. The workers may run a long way to the site just to press a button, which not only wastes time but also greatly affects efficiency. Utility Model Content

[0018] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a remote control circuit of the utility model that simulates a human clicking button operation in conjunction with the accompanying drawings.

[0019] like Figure 1 As shown in the figure, the local control panel buttons of the device are generally configured as input mode by the IO port output by the main control CPU. For example, if there are 7 buttons, there are generally 7 IO lines plus a common line. The common line is usually GND. When there is no button input, the 7 IO ports are all in a high-level state. When a button is pressed, the corresponding IO level is short-circuited with GND, that is, the level is pulled low, and then the main control CPU can detect it and perform the corresponding action output.

[0020] The utility model is a remote control circuit for simulating the operation of a person clicking a button, including a controller, a wireless communication module, a relay and a relay switch. The relay and the relay switch may include one or more, and are set according to the number of buttons. The relay is electrically connected to the relay switch, the relay switch is electrically connected to the controller, the wireless communication module is electrically connected to the controller, and the wireless communication module establishes a communication connection with an external smart device such as a mobile phone, a tablet, etc., for receiving remote control instructions. The controller is used to receive the control signal received by the wireless communication module, and control the relay to be closed or disconnected through the relay switch. The relay is a normally open small signal relay, and the passive contacts of the small signal relay are directly connected to the buttons of the local control panel of the device. In the default state, these signal relays are in a disconnected state. When the controller receives a remote button request signal through the wireless communication module, the corresponding relay is closed, and the closing time can be set. The controller controls the closing time of the relay through the relay switch, from 100ms to 3000ms, so that the short-press and long-press functions of the button can be completed, and the main control CPU can also detect it smoothly and complete the corresponding function output.

[0021] When the remote control circuit of the utility model is connected to the local control panel, the local control panel button detection IO port has a specific level signal such as 5V or 3.3V. The small signal relay cannot carry any electrical signal when connected, otherwise it will affect the original system button detection. Therefore, the passive output contacts of the small signal relay are used, which will not have any impact on the original button detection system. Example

[0022] like Figure 1As shown in the figure, it is a circuit diagram of 3 buttons. The 3 buttons are S1, S2 and S3. S1 realizes the rising function, S2 realizes the falling function and S3 realizes the stopping function. One end of S1, S2 and S3 is connected to GND, and the other end is A, B and C port respectively. The A, B and C ports are respectively connected to the three IO interfaces of the main control CPU of the control panel. The three IO interfaces output high level. When there is no button operation, the signal line level of these 3 buttons is 3.3V high level. This remote control circuit includes three small signal relays K1, K2, K3. One normally open contact of the three relays K1, K2, K3 is connected to the A, B, C ports of S1, S2, S3 respectively. The armature end D of the relay is the common end, which is connected to the GND end of the control panel respectively. The signal input end of the small signal relays K1, K2, K3 is connected to the relay switches Q1, Q2, Q3. The relay switches Q1, Q2, Q3 are connected to the controller through signal lines L1, L2, L3. The output end of the small signal relays K1, K2, K3 does not carry any electrical signal. At this point, the signal access is completed. Preferably, the relay switches Q1, Q2, Q3 are NPN transistors, the bases of the transistors Q1, Q2, Q3 are connected to one end of the resistors R1, R2, R3 respectively, the other ends of the resistors R1, R2, R3 are connected to the signal lines L1, L2, L3, the emitters of the transistors Q1, Q2, Q3 are grounded, and the collectors of the transistors Q1, Q2, Q3 are connected to the relay switches Q1, Q2, Q3 respectively.

[0023] When in use, when the controller of this remote control circuit receives the rising key signal of the remote intelligent device through the wireless communication module, the control signal line L1 outputs a high level. At this time, the transistor Q1 is turned on, and the K1 signal relay is energized. L1 is set to low after 100ms, and K1 is energized and disconnected after 100ms, simulating a short key press. Similarly, for other button operations, you only need to set the corresponding L2 and L3 signal lines high to make K2 and K3 energize. By adjusting the length of the high level, you can achieve short press, long press, and simultaneous press functions, so that the device operation can replace the human operation.

[0024] Preferably, the wireless communication module can be wireless Bluetooth, 4G or Ethernet network to adapt to different application scenarios and perform remote operation.
