[0004] The technical problem solved by this invention is to overcome the shortcomings of the prior art and propose a highly reliable ignition control system based on a dual-detection and dual-drive mechanism, which has the advantages of preventing accidental ignition, multi-channel ignition control, high safety and high reliability.

[0005] The solution of the present invention is: A highly reliable ignition control system based on a dual-detection and dual-drive mechanism includes a highly reliable ignition control system, a testing system, a PC monitoring system, and a DC power supply. High-reliability ignition control system: Receives response data transmission signals from the test system, and performs power supply identification signal detection and status identification signal detection on the response data transmission signals; when the power supply identification signal is detected as a battery power signal and the status identification signal is a release status signal, ignition control is performed to generate an ignition voltage signal, and the ignition voltage signal is fed back to the test system; otherwise, no action is taken. DC power supply: transmits power signals to the test system; Test system: Receives power signals from DC power supply; identifies the power signals as ground power signals or battery power signals; transmits the ground power signals or battery power signals to the high-reliability ignition control system to supply power to the high-reliability ignition control system; receives data stream signals from the PC monitoring system, parses the data stream signals to obtain response data transmission signals, and sends the response data transmission signals to the high-reliability ignition control system. Receives the ignition voltage signal from the high-reliability ignition control system; when the power signal is the battery power signal, extracts the voltage value of the ignition voltage signal and feeds the voltage value back to the PC monitoring system; otherwise, reception fails. PC monitoring system: generates data stream signals and sends them to the test system; receives and displays the ignition voltage value from the test system.

[0006] In the aforementioned high-reliability ignition control system based on a dual-detection, dual-drive mechanism, the high-reliability ignition control system includes an interface unit, a communication unit, a dual-switch control unit, a main control unit, an identification unit, an ignition feedback unit, and a voltage conversion unit; the dual-switch control unit includes an electromagnetic relay module and a solid-state relay module; the identification unit includes a power supply identification module and a status identification module; Interface unit: Receives the response data transmission signal output by the test system and transmits the response data transmission signal to the communication unit; Communication unit: Receives response data transmission signals from the interface unit and transmits the response data transmission signals to the main control unit; If the power supply identification module detects a battery power supply signal and the status identification module detects a release status signal, then ignition control is initiated. At this time, the dual-switch control unit first receives the first control signal from the main control unit, and uses the high or low level of the first control signal to open and close the electromagnetic relay module. When the electromagnetic relay module is in the open state, the second and third control signals from the main control unit then use the high or low level of the second and third control signals to open and close the solid-state relay module, thus achieving successful ignition control; otherwise, ignition control fails. The identification unit sends the power supply identification signal and the status identification signal to the main control unit; The main control unit receives the battery power signal, ground power signal, release status signal, and presence status signal from the identification unit and makes a judgment. If the power supply identification module detects a battery power signal and the status identification module detects a release status signal, the main control unit enters ignition control and sends a control signal to the dual-switch control unit.

When the second control signal from the main control unit is high and the third control signal is low, the solid-state relay module is in a closed state, ignition is successful, and the ignition voltage signal is transmitted to the ignition feedback unit; otherwise, it is in an open state, and ignition fails. The power supply identification module is used to detect whether the power supply signal output by the test system is a battery power signal or a ground power signal; the status identification module is used to detect whether the status identification signal output by the test system is a release status signal or an in-position status signal.

[0008] In the aforementioned high-reliability ignition control system based on a dual-detection and dual-drive mechanism, the voltage conversion unit includes a power supply input module and a power conversion module. The power input module filters the ground power signal to obtain a filtered signal, which is then transmitted to the power conversion module. In addition, the battery power signal is directly transmitted to the power conversion module. The power conversion module converts the filtered signal into a filtered power signal, and transmits the filtered power signal to the interface unit, the communication unit, the dual-switch control unit, the main control unit, the identification unit, and the ignition feedback unit.

One ignition channel requires the main control unit to send three control signals. The number of ignition control channels is determined by the number of control signals sent by the main control unit, so that each circuit is independent and does not interfere with each other, ensuring precise ignition control.

[0010] In the aforementioned high-reliability ignition control system based on a dual-detection and dual-drive mechanism, the test system includes a test interface unit, a second communication unit, a control unit, a status output unit, and a power supply unit. The test interface unit transmits the power signal to the high-reliability ignition control system through the interface cable; The second communication unit receives the data stream signal sent by the PC monitoring system and transmits it to the control unit; The control unit receives and processes the data stream signal transmitted by the second communication unit, and outputs a response data transmission signal that is transmitted to the communication unit through the communication cable; The status output unit receives the level signal output by the control unit and determines the status of the high-reliability ignition control system based on the high or low level of the signal. If the output level signal is high, the high-reliability ignition control system is in the in-position state; if the output level signal is low, the high-reliability ignition control system is in the released state. The power supply unit receives the DC power supply output signal and outputs the power signal to the high-reliability ignition control system; it also realizes voltage conversion and transmits the signal to the second communication unit, the control unit, and the status output unit.

[0014] The aforementioned high-reliability ignition control system based on a dual-detection and dual-drive mechanism also includes a power cable; the DC power supply is connected to the test system via the power cable.

[0015] The beneficial effects of this invention compared to the prior art are: (1) In the case of no power supply to the high-reliability ignition control system, the electromagnetic relay module short-circuits the positive and negative poles of the ignition signal. If current is introduced into the ignition circuit, the current can be transmitted to the ground to prevent accidental ignition when no power supply is available, thus ensuring the high reliability and high safety of the ignition control system. (2) Under the power supply of the high-reliability ignition control system, the present invention determines whether to enter ignition control through the power supply identification module and the status identification module. Ignition control is only entered when the power supply identification module detects that the signal is battery powered and the status identification module detects that the signal is released. Otherwise, ignition control is not entered to prevent accidental ignition under power supply conditions and to ensure the high reliability and high safety of the ignition control system. (3) Under the power supply of the high-reliability ignition control system, the present invention first receives the first control signal sent by the main control unit through the dual-switch control unit, and realizes the opening and closing of the electromagnetic relay module according to the high and low level of the first control signal.

The voltage value is displayed and monitored in real time through the PC monitoring system, so as to achieve successful ignition and precise control and ensure high reliability of ignition control. (4) The present invention uses a multi-channel dual-switch control unit to realize multi-channel ignition control. One ignition requires the main control unit to send three control signals. The number of ignition control channels is determined by the number of control signals sent by the main control unit, so that each circuit is independent and does not interfere with each other, ensuring high reliability of ignition control.

[0045] Figure 7 This is a structural block diagram of a multi-channel ignition control system based on a dual-detection, dual-drive mechanism, provided by the present invention. (See diagram for example.) Figure 7As shown, the high-reliability ignition control system 11 uses a multi-channel dual-switch control unit 113 to achieve multi-channel ignition control. One ignition requires the main control unit 114 to send three control signals. The number of ignition control channels is determined by the number of control signals sent by the main control unit 114, so that each circuit is independent and does not interfere with each other, ensuring high reliability of ignition.

[0046] like Figure 1 As shown, the high-reliability ignition control system based on a dual-detection and dual-drive mechanism also includes an interface cable 15; wherein the high-reliability ignition control system 12 is connected to the interface unit 111 via the interface cable 15.

[0050] In the absence of power supply to the high-reliability ignition control system 11, the electromagnetic relay module 1131 short-circuits the positive and negative terminals of the ignition signal. If current is introduced into the ignition circuit, it can transmit the current to the ground, preventing accidental ignition in the absence of power supply and ensuring high reliability and high safety of ignition control.

[0051] In the case of a high-reliability ignition control system 11 being powered, the present invention determines whether to enter the ignition process through a power supply identification module 1151 and a status identification module 1152. The ignition process is only entered when both the power supply identification module 1151 detects a battery-powered signal and the status identification module 1152 detects a released state.

[0052] In the case of a high-reliability ignition control system 11, the present invention first receives a first control signal from the main control unit 114 via a dual-switch control unit 113. The electromagnetic relay module 1131 is opened and closed based on the high and low levels of the first control signal. When the electromagnetic relay module 1131 is in the open state, the second and third control signals issued by the main control unit 114 are then used to open and close the solid-state relay module 1132 based on the high and low levels of the second and third control signals. The voltage value is displayed and monitored in real time by a PC monitoring system 13, thereby achieving successful ignition and precise control, and ensuring high reliability of ignition control.

[0053] This invention employs a multi-channel dual-switch control unit 113 to achieve multi-channel ignition control. One ignition channel requires the main control unit 114 to send three control signals. The number of ignition control channels is determined by the number of control signals sent by the main control unit 114, ensuring that each circuit is independent and does not interfere with each other, thus guaranteeing precise ignition control.

[0054] In the absence of power supply to the high-reliability ignition control system, the electromagnetic relay module short-circuits the positive and negative terminals of the ignition signal. If current is introduced into the ignition circuit, it can transmit the current to the ground, preventing accidental ignition in the absence of power supply and ensuring the high reliability and safety of the ignition control system.

[0055] This invention, under the power supply condition of a highly reliable ignition control system, determines whether to enter ignition control through a power supply identification module and a status identification module. Ignition control is only entered when both the power supply identification module detects a battery-powered signal and the status identification module detects a released state; otherwise, ignition control is not entered. This prevents accidental ignition under power supply conditions and ensures high reliability and high safety of the ignition control system.

[0056] In a high-reliability ignition control system, this invention first receives a first control signal from the main control unit via a dual-switch control unit. The electromagnetic relay module is opened and closed based on the level of this first control signal. When the electromagnetic relay module is open, the second and third control signals from the main control unit are used to open and close the solid-state relay module based on their respective levels. The voltage value is then displayed and monitored in real-time via a PC monitoring system, ensuring successful ignition and precise control, thus guaranteeing high reliability of the ignition control.
