When the button and the reset switch are turned on at the same time, the control signal is transmitted to the encoding chip.

[0022] In some embodiments of the present invention, Figure 3 As shown, the input module is a key array module, and the key array module includes a key array and an encoding module; The key array is used to receive a control signal input by a user; The encoding module is used to encode the control signal to match the corresponding input port.

[0023] According to the unit support control system provided by the present invention, the input module is an address selection module, and the address selection module is used to receive a control signal from a user and match a corresponding input port according to the control signal.

[0024] In the embodiment of the present invention, Figure 4 As shown, the controller also includes: The decoding module is used to decode the received control signal according to the encoding rule of the encoding module to obtain the corresponding output port when the input module is a key array module.

[0025] In an embodiment of the present invention, the encoding module includes a 4-state encoding mode, an 8-state encoding mode, and a 16-state encoding mode; Correspondingly, the decoding module includes a 4-state decoding mode, an 8-state decoding mode and a 16-state decoding mode.

[0026] In the embodiment of the present invention, by configuring a plurality of state modes through the encoding module and the decoding module, the control port expansion can be realized to meet the requirements of controlling the scene of multiple unit brackets at the same time.

[0027] Based on any of the above embodiments, Figure 5 As shown, the controller also includes a battery and a self-locking switch, the battery is used to power the decoding chip, the self-locking switch is arranged on the connection line between the battery and the decoding chip, and the self-locking switch is used to control whether the connection line between the battery and the decoding chip is conductive.

[0028] In an embodiment of the present invention, the controller further comprises a DC / DC converter; The DC / DC converter is connected to the battery and the decoding chip respectively, and is used for converting the direct current provided by the battery into a voltage suitable for the operation of the decoding chip.

[0029] Based on any of the above embodiments, the control signal of the input port corresponding to the encoding chip is a complete codeword consisting of an address code, a data code, and a synchronization code. The address code is used to identify the identity of different ports to ensure that only the receiving antenna with the same address code as the transmitting antenna receives the control signal. After receiving the control signal, the decoding chip checks the parsed address code multiple times. After the check result is passed, the corresponding output port is controlled to output a high level. The data code is used to represent the actual control command or information, and the decoding chip reads the control command or information and controls the corresponding bracket to perform the corresponding action; The synchronization code is used to assist the receiving antenna in capturing the starting point of the incoming signal and to keep the control signal synchronized between the transmitting antenna and the receiving antenna.

[0030] The unit bracket is, for example, a single bracket such as a stack bracket, a shield bracket, a withdrawal bracket, and a slag blocking bracket. In the embodiment of the present invention, the encoding chip and the decoding chip take the PT2262 / 2272 chip as an example. The PT2262 / 2272 chip can have up to 12 bits (A0-A11) of three-state address terminal pins (suspended, connected to a high level, connected to a low level), and any combination can provide 531441 address codes. The encoding chip PT2262 can have up to 6 bits (D0-D5) of data terminal pins. The set address code and data code are serially output from pin 17, which can be used for wireless remote control transmission circuits. The encoding signal sent by the encoding chip PT2262 consists of: address code, data code, and synchronization code to form a complete code word. After the decoding chip PT2272 receives the signal, its address code is compared and checked twice, and the VT pin outputs a high level. At the same time, the corresponding data pin also outputs a high level. If the sending end keeps pressing the button, the encoding chip will also transmit continuously. When no button is pressed on the transmitter, PT2262 is not powered on, its pin 17 is at a low level, and the 315MHz high-frequency transmitting circuit does not work. When a button is pressed, PT2262 is powered on and its pin 17 outputs a modulated serial data signal. When pin 17 is at a high level, the 315MHz high-frequency transmitting circuit starts to oscillate and transmits a high-frequency signal of equal amplitude. When pin 17 is at a low level, the 315MHz high-frequency transmitting circuit stops oscillating. The high-frequency transmitting circuit is completely controlled by the digital signal output from pin 17 of PT2262, thereby completing amplitude keying (ASK modulation) for the high-frequency circuit, which is equivalent to amplitude modulation with a modulation index of 100%.

[0031] The unit bracket control system provided in the embodiment of the present invention realizes a unit bracket remote control system without MCU and programming, so as to simplify the system, reduce cost and difficulty in using technology, and improve stability, so as to solve the problems of complex control, high technical requirements and high cost of existing unit brackets, and the wireless transmission has strong anti-interference ability, thereby improving the control stability of the unit bracket.

[0032] The embodiment of the present invention also provides a unit hydraulic support control system, such as Figure 6 As shown, it includes the unit bracket control system, the electromagnetic pilot valve and the hydraulically controlled reversing valve as described in any one of the above embodiments; The switch array in the unit bracket control system is connected to the electromagnetic pilot valve, and the electromagnetic pilot valve is connected to the hydraulically controlled reversing valve; After the corresponding switch of the switch array is turned on, the electromagnetic pilot valve is powered on to drive the hydraulically controlled reversing valve to turn on the hydraulic circuit, so that the hydraulic support arranged in the hydraulic circuit is activated.

[0033] In the embodiment of the present invention, the remote controller is a handheld device for the remote operator, and the controller is an electromagnetic pilot valve driving device installed on the bracket. The encoding and decoding chips with wireless functions are respectively integrated in the remote controller and the controller. In addition to the corresponding ports with the same address setting, the number of input ports of the encoding chip corresponds to the number of output ports of the decoding chip. When a key signal is input to a port of the encoding chip, a high level will be output on the corresponding port of the decoding chip. The high level can drive the MOS or relay to turn on, and the battery power supply supplies power to the corresponding electromagnetic pilot valve port, the hydraulic circuit of the hydraulic control reversing valve is turned on, and the hydraulic bracket is actuated. Since the number of control ports of the encoding and decoding chips is limited, in order to control the number of electromagnetic pilot valves greater than the number of ports, the expansion of the control port can be achieved by adding encoding modules and decoding modules.
